Background: Clinical handover between emergency medical services (EMS) and the hospital trauma team can be subject to errors that may negatively affect patient care. Thus far, there has been limited evaluation of the quality of EMS handover. As such, we sought to characterize handover practices from EMS to the trauma team, identify areas for improvement, and determine if there is a need for standardization of current handover practices. Aim Statement: Identify areas for improvement in handover from EMS to the trauma team, specifically examining handover content, structure, and discordances between different team members regarding handover expectations. Measures & Design: Data were prospectively collected over a nine week period by a trained observer at Canada's largest level one trauma centre. A randomized scheduled was used to capture a representative breadth of handovers. Data collected included outcome measures such as duration of handover, structure of the handover, and information shared, process measures such as questions and interruptions from the trauma team, and perceptions of the handover from nurses, trauma team leaders (TTLs) and EMS according to a bidirectional Likert scale. Evaluation/Results: Of 410 trauma team activations, 79 verbal handovers were observed. Information was often missing regarding airway (present 22%), breathing (54%), medications (59%), and allergies (54%). Handover structure lacked consistency beyond the order of identification and mechanism of injury. Only 28% of handovers had a dedicated question and answer period. Of all questions asked, 35% were questioning previously given information. EMS returned to categories of information unprompted in 84% of handovers. The majority of handovers (61%) involved parallel conversations between team members while EMS was speaking, which was associated with a greater number of interrupting questions from the trauma team (3.15 vs. 1.82, p =.001). There was a statistically significant disparity between the self-evaluation of EMS handovers and the perceived quality determined by nurses and trauma team leaders. Discussion/Impact: At our trauma centre, we have identified the need for handover standardization due to poor information content, a lack of structure and active listening, significant information repetition, and discordant expectations between EMS, nurses, and TTLs. We intend to use our results to guide the development of a co-constructed framework integrating the perspectives of all team members on the trauma team.

A handover strategy is required to ensure connection continuity for cellular network users due to user mobility. Handovers on the same frequency (intra-frequency) and handovers on other frequencies (inter-frequencies) are conceivable in the Intra Radio Access Technology network. The network must be able to give the best quality and optimal bandwidth so that consumers can keep their connection. Most cells have more than one bandwidth channel. A test was performed in this study to determine the influence of priority handover on intra-frequency LTE handover on signal strength and throughput. This study is based on actual measurement findings from the deployed 4G LTE network transceiver device, which contains several carriers for each eNodeB. TEMS Pocket, a mobile gadget, was used to collect data for measurements. For analysis purposes, the parameters RSRP, throughput, frequency band, serving cell identification or PCI (Physical Cell Identity), and event handover are employed. In the inter-frequency LTE handover, there are two priority handovers: handovers from lower bands to higher bands (high priority) and handovers from higher bands to lower bands (low priority). When a low-priority handover happens, the RSRP value and throughput increase, while a high-priority handover causes the RSRP value to decrease.

BackgroundStructured handover can reduce communication breakdowns and potential medical errors. In our emergency department (ED) we identified a safety risk due to variation in quality and content of overnight handovers between physicians.AimOur goal was to develop and implement a standardised ED-specific handover tool using quality improvement (QI) methodology. We aimed to increase the proportion of patients having adequate handover information conveyed at overnight shift change from a baseline of 50%–75% in 4 months.MethodsWe used published best practices, stakeholder input and local data to develop a tool customised for intershift ED handovers. Implementation methods included education, cognitive aids, policy change and plan-do-study-act cycles informed by end-user feedback. We monitored progress using direct observation convenience sampling.MeasuresOur outcome measure was proportion of adequate patient handovers (defined as >50% of handover components communicated per patient) per overnight handover session. Tool utilisation characteristics were used for process measurement, and time metrics for balancing measures. We report changes using statistical process control charts and descriptive statistics.ResultsWe observed 49 overnight handover sessions from 2017 to 2019, evaluating handovers of 850 patients. Our improvement target was met in 10 months (median=76.1%) and proportion of adequate handovers continued to improve to median=83.0% at the postimprovement audit. Written communication of handover information increased from a median of 19.2% to 68.7%. Handover time increased by median=31 s per patient. End-users subjectively reported improved communication quality and value for resident education.ConclusionsWe achieved sustained improvements in the amount of information communicated during physician ED handovers using established QI methodologies. Engaging stakeholders in handover tool customisation for local context was an important success factor. We believe this approach can be easily adopted by any ED.

This study aims to analyze the application of the SBAR method of handover management innovation in improving effective communication. The method used is a case study that starts from the process of identification, analysis, problem priority setting, plan of action (POA), implementation and evaluation. Data collection was done by interview, observation and survey methods. The results of the priority problems were analyzed using fishbone analysis. The results showed that the SBAR method of handover management innovation influenced the team leader's ability to carry out handovers. The evaluation results show that 75% of the team leaders can properly fill out handover forms and submit handovers using the SBAR method. In conclusion, the SBAR method of handover management innovation can be used to improve handover capabilities to improve effective communication.

Communication failures in information transfer during intraoperative handover can pose a risk to patient safety incidents. One of the factors influencing the success of intraoperative handover is the existence of a structured handover checklist. This study aimed to explain the implementation of a structured intraoperative handover checklist to improve information transfer during intraoperative handovers. The design employed was a literature review. Articles were selected from databases including ScienceDirect, Scopus, PubMed, and Springer Link. The criteria for article selection included publication between 2017 and 2022, full text in English, and the use of keywords such as 'intraoperative handover,' 'handover checklist,' and 'information transfer.' The PRISMA flowchart stages were utilized to filter appropriate articles. The critical assessment of article quality employed The Joanna Briggs Critical Appraisal Tools 2020 and Mix Methods Appraisal Tool 2018. The results of the review of 8 articles indicated that a lack of good coordination during intraoperative handovers often occurs due to the absence of structured guidelines regarding handover content. The application of an intraoperative handover checklist has been shown to increase the completeness of data transfers and reduce the percentage of information omission during the handover process. The implementation of structured intraoperative handovers has a positive influence on improving the quality of communication between surgical teams and reducing incomplete information conveyed. A structured intraoperative handover checklist is needed as a guide to reduce the number of errors in information transfer, thus enhancing patient safety.

ObjectivesTo investigate residents’ and relatives’ views and experiences of handovers in care homes. This paper reports residents’ and relatives’ awareness of handovers, knowledge of and views on handover practices and purpose, and views on handover effectiveness. Outcomes, safety and satisfaction in clinical settings are influenced by shift handovers. Despite this link with quality, residents’ increasing support needs and the provision of 24 hours care in care homes for older people, little is known about handovers in these settings from a resident and visiting relative perspective.SettingFive purposively sampled care homes for older people in South East England.ParticipantsHome managers (n=5), residents (n=16) relatives of residents (n=10) were interviewed; residents (n=15) and their interactions with staff were observed during handover periods. Participation was voluntary and subject to consent. Residents were identified by managers as having mental capacity to take a decision about participation which was then assessed. An ethnographic approach to data collection was taken, preceded by an evidence review.ResultsShift handovers were largely invisible processes to participating residents and relatives, many of whom had given little thought to handover practice, logistics or effectiveness prior to study participation. Their awareness and understanding of handovers, handover practices, and handover purpose and effectiveness varied. There appeared to be an underlying assumption that administrative procedures in care homes would operate without input from residents or relatives. A small number of residents, however, were highly aware of the routine of handovers and the implications of this for the timing of and response to their requests for care or support.ConclusionsThe care home setting and perspectives of the effectiveness of handovers may influence awareness of, knowledge of and levels of interest in involvement in handovers.

AimsThis project was undertaken in the Tyrone and Fermanagh Hospital, an inpatient Psychiatric Unit in Omagh, Northern Ireland. It was recognised that the previous method of medical handover via anonymised WhatsApp messages had several issues including patient data on personal phones, over-reliance on phone apps which have the potential to crash and short messages with limited details were included. The aim of our project was to improve patient safety by improving communication between medical staff members.MethodsThe previous method of medical handover was via text message on messaging platform WhatsApp. A message was sent the morning of handover, to the WhatsApp group.We continued to use a digital platform, but used Microsoft word, and Western Trust email addresses to record and send the handover. At the start of this project, we allowed free space recording, resulting in variation in the handovers.We agreed a minimum number of details to be included to ensure quality of handover, and audited the word documents, to assess the adherence to this.This change, still does not require face to face handover. There have been pros and cons to the change, which will be discussed in this presentation.We reviewed four months’ worth of handovers. They were reviewed for specific elements of essential handover criteria. The areas included Patient Name, H&C, detained or voluntary, admission or review, presenting complaint, patient's history, risks, physical issues, and handover to specific person.It should be noted that the doctors involved were aware of the changes made, and standards being introduced, and therefore were aware that they would be auditing their own handovers. This might have created bias in the subsequent handovers.We then analysed each month to see what percentage of handovers had been concordant with the standards. These data were then represented in graphs, as we will show.ResultsWe identified areas which were performed well when completing handover. The areas which were consistently 100% included the date of handover and patient name or initials. Outstanding jobs were performed in 97.5% of handovers.Areas for improvement identified when collecting results were the status of admission (i.e. voluntary or detained), the main patient risks and use of the document password.100% of the shifts used the new digitalised format for handover using Microsoft word and trust email system.ConclusionWe reviewed the results of the data, which highlighted areas for improvementWe hope to implement a standard performa for handovers, reducing the chance of key information being missed, thereby improving patient safety. We aim to collect data following this 2nd intervention in the next rotation and continue to examine handover processes using PDSA cycles.

Abstract Background High-quality, shift-to-shift handovers by residents are critical to ensuring to patient safety. The 2011 Accreditation Council for Graduate Medical Education duty hour requirements have increased the number of handovers occurring daily, necessitating new approaches to this challenge. Research suggests standardized approaches, electronic systems, and education programs can improve the handover process. Methods We conducted a 2-phase, observational study comparing an electronic handover system (experimental) in one clinical setting to a standard card-based system (control) at a second site. Outcome data included an objective assessment of the completeness and accuracy of handovers, and resident assessment of the handover systems. In phase 1, data were recorded at both sites and not shared with residents. In phase 2, data from the experimental system were used to provide standardized feedback to residents on the quality of their handovers. Results A total of 3184 individual patient sign-outs were evaluated during the 11-month period. Following introduction of a feedback intervention in the experimental arm, errors were present in only 5.2% of handovers, compared with 16.1% of controls (P < .001), and 67% of the 38 residents responding reported they perceived the experimental system as facilitating better patient care. Conclusion Regular, real-time feedback through an electronic handover system can improve the accuracy and completeness of handovers in patient care.

(1) Background: we compare a new SBAR based electronic handover tool versus a paper-based checklist for handover in a pediatric intensive care unit (PICU). (2) Methods: this is a randomized, observational study of 40 electronic vs. 40 paper checklist handovers after pediatric cardiac surgery, with a 48 items checklist for comparison of reporting frequencies and notification of disturbances and noise. PICU staff satisfaction was evaluated by a 12-item questionnaire. (3) Results: in 14 out of 40 cases, there were problems with data processing (incomplete or no data processing). Some item groups (e.g., hemodynamics) were consistently reported at higher frequencies than other groups. Items not specifically asked for did not get reported. Some items, automatically processed in the SBAR handover page, did not get reported. Many handovers suffered a noisy and distracting atmosphere. There was no difference in staff satisfaction between the two handover approaches. Nurses were highly unsatisfied with the general approach by which the handover was performed. (4) Conclusions: human error appears to be a main factor for unreliable data processing. Software is still too complicated, and multitasking is a stressful and error prone event. Handover is a complex task with many factors required for a successful completion.

Introduction: There is a high risk for communication breakdown, discontinuity of clinical care, and medical errors during ED physician handover. Locally, there is no standardized handover process to ensure adequate communication of critical information. Our aim was to use a locally developed handover tool to increase frequency of adequate physician handover during overnight shift change by 50% in 4 months. Methods: Using published best practices, local observational data, and stakeholder input, we determined critical components of ED handovers. We developed a structured communication tool for two unique populations in our ED: ED-VITAL for patients receiving active ED care; ED-VSA for patients who are admitted/referred. Strategies used to implement the tool included: engagement of staff physicians to introduce & modify the tool; formal education and training to ED residents; and provision of cognitive aids. A QI coordinator conducted direct observations of handovers using convenience sampling. We provided feedback to staff and resident physicians, and used their input to continuously modify the tool. The main outcome measure was adequate patient handover, defined as verbal communication of 50% of critical handover components, or documentation of key information on an electronic note. Process measures included tool utilization characteristics. Balance measures included time metrics such as handover duration. We present run charts and qualitative statistics. Results: We assessed 368 individual patient handovers (93 pre- & 275 post-implementation). The median proportion of patients in active ED care who were verbally handed over increased from 75% to 100%. The median proportion of adequate handovers improved from 50% to 72%. The time to deliver handover increased by 13 seconds per patient. Qualitative feedback from end users was positive overall, particularly for communication quality and resident educational value. Conclusion: Use of a standardized handover tool improved both verbal and documented communication during shift change. A customized approach, sensitive to local context, was important to successful implementation. Residents play a large role in handovers; strategies to improve handover processes that emphasize medical education appear to enhance success. Future PDSA cycles will focus on interventions to further enhance the utilization of the tool, and to measure direct impact on clinical outcomes.

Background/Aims To observe and compare existing nursing handover practice with national recommendations and establish a local model to facilitate the implementation, monitoring and maintenance of best practice. Methods Nursing handover practice was observed using a defined format, collecting qualitative data on structure, safety issues, communication, transfer of information, relevance, and record accuracy and timeliness. Focus groups employed structured interviews regarding effective nursing handover practices based on open-ended questions. These sessions were audio-recorded using transcription conventions that indicate basic conversational turn taking. Results The observed handovers revealed several deficiencies including an inadequate location for the handover, a lack of a structured model and failures in communication. However, in 80% of cases, time was set aside for a handover and this was well attended. Conclusion Current handover practice is inadequate and needs improvement. Nursing culture is shaped by many internal factors, including barriers such as poor communication and leadership. Additionally, a shared mental model among the nursing team offers effective information transfer by concise, factual communication. Structuring a handover using the situation, background, assessment, and recommendations can provide a standard communication framework for patient care handovers.

BackgroundIrregular patient volumes, high patient transit and limitless presentations means that Emergency Department (ED) handovers differ from other specialities. Therefore, a degree of handover unfamiliarity results for junior doctors.There is a high prevalence of stress and burnout in both junior doctors and doctors working in Emergency Medicine. Despite this, no literature was identified exploring if handover can be a source of stress. The aim of this study was to explore junior doctors’ perceptions of ED handover and to investigate if it is considered a stressful experience.Non-probabilistic sampling methods were used to recruit doctors working at or below the grade of Speciality Trainee year 2 (ST2) or equivalent in the ED of a major acute teaching hospital. Qualitative, semi-structured interviews were undertaken between March and April 2019 exploring participants’ experiences of ED handover. Interviews were recorded and transcribed verbatim. Using NVivo 12 software, data were analysed thematically using an inductive-deductive approach.10 interviews were undertaken and four themes were identified from the data: ‘stress decreases as familiarity increases’ which included familiarising with handover structure, content and purpose; ‘time pressure is an ongoing stressor’ representing the perceived need to efficiently handover during busy periods and at shift end; ‘handover as a solace’ relating to opportunities to both learn and socialise and ‘it’s nice to be nice’ reflecting the importance of civility.Junior doctors find aspects of ED handover stressful. These include: wanting to make a good impression; unfamiliarity; time pressures and the negative effects of hierarchy. However, handover can also help to ameliorate stress by facilitating opportunities for socialisation, education and morale boosting. Important recommendations for future practice regarding departmental handover can be made, most notably, the need to create a civil and pleasant working environment where doctors can flourish.Abstract 038 Figure 1Four themes explainedAbstract 038 Figure 2Recommendations for future handovers

Introduction Beyond the provision of services, quality of care and patient safety measures such as optimal clinical handover at shift changes determine maternity outcomes. We aimed to establish the proportion of women handed over and the content of clinical handovers and communication between shifts within 3 diverse obstetrics units in Kerala, India, and to describe the handover environment. Methods A cross sectional study was conducted for six weeks during February and March 2015at three hospitals in Kerala, India, during nurses obstetric handover in one tertiary private, one tertiary government and one secondary government hospital. Nursing handovers in obstetric post-operative, in-patient and labour wards were sampled. An SBAR-based (situation, background, assessment and recommendation) data schedule was completed whilst observing handover at nursing shift changes. Since obstetricians had no scheduled handover, qualitative interviews were conducted with obstetricians in two hospitals to establish how they acquire information when beginning a shift. Results Data was obtained on 258 patients handed over, within 67 shift changes. The median percentage of women handed over was 100% in two of the hospitals and 27.6% in the other. The median number of information items included out of a possible 25 was 11, 5 and 4,and did not change significantly for women with high-risk status. Important items regarding assessment and recommendation for care were often missed, including high-risk status. The median number of environment items achieved was good at 7 out of 10 in all hospitals. Obstetricians sought information in various ways when required. All supported the development of structured tools, face-to-face and team handovers. Conclusions Maternity unit handovers for doctors and nurses were inadequate. Ensuring handover of all women and including critical information, between shifts as well as between doctors, needs to be improved to increase patient safety.

As much as 80% of the issues that result in medical errors are related to handover. One endeavor to increase patient safety at the hospital is the use of SBAR communication during handovers. The management duties of the head of the room, such as checking, directing, and evaluating the implementation of the handover, are directly tied to the effectiveness of implementing efficient communication during a handover. SBAR communication during handovers is a problem that happens in Pringsewu Hospital. The objective of this study is to determine the correlation between head management function and the implementation of handovers using SBAR communication at Pringsewu Regional Hospital.
This research type is quantitative. The research design used a descriptive correlation using a cross-sectional approach. This research was conducted at the Pringsewu Regional Hospital in May 2023. The total population was 70 nurses in 5 inpatient rooms. The sampling technique uses total sampling. The data collection instrument used a questionnaire and data analysis used the Fisher's exact test.
The results showed that there is a correlation between the room head management function and the implementation of handover using SBAR communication, with a p-value = 0.007. It is expected that the head of the room will improve the 5 management functions of the head of the room, especially the supervisory function so that handovers using SBAR communication can be carried out optimally.

The Handover process is an essential aspect of patient care in daily clinical practice to ensure continuity of patient care. Standardization of clinical handover may reduce sentinel events due to inaccurate and ineffective communication. Single arm experimental trial was conducted to assess the effect of standard Situation, Background, Assessment, Recommendation (SBAR) protocol implementation in overall bedside nursing handover process, patient satisfaction, and nurses’ acceptance. As a sample, all nursing staff of specified unit, all handover process performed by them, and patients admitted during study the period were included. Initially, the prevailing handover process and patient satisfaction regarding nursing handover was assessed using a structured observation checklist. During the implementation phase, nurses were trained on an SBAR handover protocol. After implementation, nursing handovers were again assessed and data regarding patient satisfaction and nurses’ acceptance were collected. There was a statistically significant difference ( P < .05) in median scores between the pre and post-intervention group on overall nursing handover and patient satisfaction regarding nursing handover. Standardization of patient’s handover process is effective in terms of improving nursing handover process, patient satisfaction, and health professionals’ acceptance.

Prevailing personal mobile network architectures make use of streamlined mobility control system, where the complete understanding is concentrated on single-end that results in scarce of dynamic mobility support when data volume is found to be large. The present-day networks necessitate seamless connections regardless of node position and connectivity that has to be accomplished between personal are network (PAN). In this work, a novel method called, Markov Renewal Prediction and Radial Kronecker Neural Network (MRP-RKNN) based optimized handover for seamless mobility in PAN is proposed. By employing a Markov Renewal Prediction model for Seamless Mobility along with the two-hop network architecture, in this paper, we propose a transition probabilities (TP) function to mitigate the persistent handover issue in conventional wireless communication systems. The proposed Markov Renewal Prediction model for Seamless Mobility significantly reduces handover execution time and seamless mobility handover accuracy with efficient transition probabilities. In PANs, the unavoidable deployment of low power sink nodes permits the mobile nodes with many issues in terms of Quality of Service (QoS) due to complication of recurrent handovers due to high mobility. Addressing this issue of handover optimization in the deployment of PAN, this work proposes a model called to optimize the handovers in a cost-efficient manner. In this work, Radial Kronecker Delta Neural Network is utilized for handling frequent handovers based on received signal strength and cost metrics. Here, the resultant desired output is obtained using the Radial Kronecker function being a function of two variables with which optimized handover is performed.

Introduction: Ideally, a handover is carried out through three stages: preparation, implementation, and post-handover. However, some handovers only consist of one phase. The aim of the study was to identify and analyze the factors related to the implementation of nurse handover.Methods: This was a correlative analytic research method with a cross-sectional approach. The population in this study was all of the nurses with at least a Diploma III inpatient ward education. The sample totaled 174 nurses in the inpatient ward of Ulin Hospital Banjarmasin, recruited through proportionate stratified random sampling. The data was collected by spreading the questionnaire and the data collection took place from December 2017 to January 2018.Results: There was a correlation between education level (p= 0.036) and role model (p= 0.021) with the implementation of handover. The most dominant factor associated with the implementation of handover was role model (p= 0.031: OR= 6.089).Conclusion: The nurses who had a good role model performed th handover 6.089 times better than the nurses with an inadequate role model. Adversely, a poor role model might result in a poor handover.

Full textAbstract:
Background. Bedside nursing handover is a recognized nursing practice that involves conducting shift change communication at the patient’s bedside to enhance communication safety. Understanding the perceptions of both patients and nurses regarding bedside handover is crucial in identifying the key principles for developing and implementing effective bedside handover protocols. However, there is currently a lack of comprehensive evidence that summarizes and evaluates studies focused on qualitative approaches for gaining insights into the perceptions of both nurses and patients. Purpose. This meta-synthesis review aims to identify, synthesize, and evaluate the quality of primary qualitative studies on the perceptions of patients and nurses about bedside nursing handover. Methods. A meta-synthesis review was conducted to identify qualitative studies that reported patients and nurses’ perceptions about bedside handover using seven electronic databases, including CINAHL, PsycINFO, Embase, Education Database (ProQuest), Web of Science, The Cochrane Library, and PubMed, from January 2013 to November 2023. The authors independently selected reviews, extracted data, and evaluated the quality of included studies using the 10-item JBI Qualitative Assessment and Review Instrument tool. Results. A total of 871 articles were retrieved, of which 13 met the inclusion and exclusion criteria. These studies identified three main themes: (1) facilitators of bedside nursing handover, (2) barriers to bedside nursing handover, and (3) strategies to maintain confidentiality during bedside handover. Conclusion. This study systematically reviewed and integrated the perceptions of patients and nurses about bedside handover. Based on nurses’ perceptions, the combined findings highlight the facilitators of bedside handover, including developing partnership interaction between nurses and patients, promoting professionalism, and enhancing emotional communication among nurses. From the patients’ viewpoint, the synthesized findings emphasize the facilitators of bedside handover, including acknowledging the expertise, professionalism, and humanity of the nursing profession, ensuring a sense of safety, satisfaction, and confidence in the care received, as well as promoting individualized nursing care. In the context of barriers to bedside handover, both nurses and patients perceive breaches of confidentiality and privacy violations as significant barriers. When it comes to maintaining confidentiality during bedside handovers, it is important to consider patients’ preferences. Patients often prefer handovers to take place in a private setting. From the nurses’ perspective, it is important to inquire with patients about their preference for the presence of caregivers, and to conduct private handovers for sensitive issues away from the bedside. Relevance to Clinical Practice. Clinicians should carefully evaluate the barriers and facilitators in this meta-synthesis prior to implementing bedside handover. Study Registration. This study is registered in PROSPERO with Protocol registration ID: CRD42024514615.

Full textAbstract:
The non-terrestrial network (NTN) is a network that uses radio frequency (RF) resources mounted on satellites and includes satellite-based communications networks, high altitude platform systems (HAPS), and air-to-ground networks. The fifth generation (5G) and NTN may be crucial in utilizing communication infrastructure to provide 5G services in the future, anytime and anywhere. Based on the outcome of the Rel-16 study, the 3rd generation partnership project (3GPP) decided to start a work item on an NTN in 5G new radio (NR) Rel-17, and the focus of the study was on mobility management procedures, due to the movements of NTN platforms; especially, low earth orbit (LEO) satellites. Handover enhancements were discussed to tackle the frequent handover due to the fast satellite movement. Therefore, the major problem of handover in LEO satellite systems was the signaling storm created by handing over all user equipment (UE) in a cell to a new cell because when the UE crosses the boundary between the neighboring cell of a satellite, an intra-satellite or cell handover occurs; thus, all users in a cell are expected to experience a change of cell due to handover every few seconds. In addition, UE location is not easy to define due to moving cell/beam situations. In this study, we propose machine learning-based solutions for handover decisions in non-terrestrial networks for cell handovers or intra-satellite handovers to reduce signaling storms during handovers where the handover requests will be executed by clustered users. First, the dataset was generated by the simulator that simulates communication between users and satellites. Second, we preprocessed the data, and also used the feature creation technique to create the distance feature using the Haversine formula, and then applied clustering and classification algorithms. The experimental results show that the distance between a user and its cell center is an important parameter for handover decisions in NTN, and the random forest outperforms all models with a higher accuracy of 99% along with a better F1-score of 0.9961.

AimsEfficient handovers are integral to patient care. Challenges to handover for wards include high patient turnover and varied handover approaches between wards, as well as admissions out of hours. Patients on Old Age Wards often have multiple comorbidities and can deteriorate rapidly without coordinated care. Our focus was on improving handover of patients transferred between the Old Age Admissions Ward and Rehabilitation Ward. We aimed to create a ward handover protocol to improve compliance with documenting a pretransfer plan and ensure there was an 80% compliance with completing this plan within 3 months.MethodAn MDT discussion took place in order to explore change ideas. Questionnaires were filled out post implementation of protocol. A handover proforma was designed to capture important patient data and continuing plans. A PDSA cycle was designed to deliver a structured handover.Per patient measures were collected including: whether a handover took place, recording of current medical and psychiatric issues, documentation of plan and was the plan put into action or reviewed.MDT feedback was collected on satisfaction with the protocol and handover process using open questions and Likert scale.ResultPrior to the establishment of the proforma there was no verbal or written handover between wards. In 28% of cases prior to the intervention, blood results were checked and medication reviews took place within the timeframe written in the patient's notes. A proforma was initiated and used for 93% of patient handovers between wards. Blood results were checked according to the planned timeframe in 86% of cases. Where the handover proforma took place, 100% of patients had a medications review. Qualitative detail revealed that key patient appointments such as MRI Brain scans and important plans such as fluid restriction limits were missed before implementing the protocol. Aftewards complex patient plans were recorded and implemented accordingly.Questionnaire feedback was positive and MDT found the proforma to be helpful and to improve patient safety.ConclusionThe team viewed the new handover pathway as a positive patient safety tool. Compliance with completing the protocol in the longer term and maintaining change is an area for ongoing improvement.

Abstract Background The Accreditation Council for Graduate Medical Education requires residency programs to ensure safe patient handovers and to document resident competency in handover communication, yet there are few evidence-based curricula teaching resident handover skills. Objective We assessed the immediate and sustained impact of a brief educational intervention on pediatrics intern handover skills. Methods Interns at a freestanding children's hospital participated in an intervention that included a 1-hour educational workshop on components of high-quality handovers, as well as implementation of a standardized handover format. The format, SAFETIPS, includes patient information, current diagnosis and assessment, patient acuity, a focused plan, a baseline exam, a to-do list, anticipatory guidance, and potential pointers and pitfalls. Important communication behaviors, such as paraphrasing key information, were addressed. Quality of intern handovers was evaluated using a simulated encounter 2 weeks before, 2 weeks after, and 7 months after the workshop. Two trained, blinded, independent observers scored the videotaped encounters. Results All 27 interns rotating at the Children's Hospital consented to participate in the study, and 20 attended the workshop. We included all participant data in the analysis, regardless of workshop attendance. Following the intervention, intern reporting of patient acuity improved from 13% to 92% (P < .001), and gains were maintained 7 months later. Rates of key communication behaviors, such as paraphrasing critical information, did not improve. Conclusions A brief educational workshop promoting standardized handovers improved the inclusion of essential information during intern handovers, and these improvements were sustained over time. The intervention did not improve key communication behaviors.

Background: As physicians reduce their work hours, transfer of patient care becomes more common; this is a time of heightened risk to patients. Training in patient handover skills may reduce this risk. The objective of this study was to systematically review the literature regarding education models available to teach handovers skills to healthcare professionals. Methods: A systematic review was conducted to identify published educational resources on patient handover skills. Two investigators independently reviewed publications for inclusion/exclusion. A third reviewer resolved any disagreement. Included papers contained an educational resource for teaching handover skills to any health profession in any patient population. Papers were rated on a previously described 4 point scale for quality. Results: 1746 papers were identified, of which twelve met the inclusion criteria These studies presented information on educational curricula, simulation technologies and didactic sessions. The most common educational method was simulation or role-playing, which is better received by learners than didactic sessions. Teaching handover practices makes residents feel more confident in their handover, and residents receiving adequate handover are more comfortable with their duties.Conclusions: Although data are limited, effective training models for handover skills have been described in the literature. Residents and other healthcare practitioners should receive training in handover to improve practitioner comfort and patient care.

Full textAbstract:
Handover Management (HM) is pivotal for providing service continuity, enormous reliability and extreme-low latency, and meeting sky-high data rates, in wireless communications. Current HM approaches based on a single criterion may lead to unnecessary and frequent handovers due to a partial network view that is constrained to information about link quality. In turn, HM approaches based on multicriteria may present a failure of handovers and wrong network selection, decreasing the throughput and increasing the packet loss in the network. This paper proposes SIM-Know, an approach for improving HM. SIM-Know improves HM by including a Semantic Information Model (SIM) that enables context-aware and multicriteria handover decisions. SIM-Know also introduces a SIM-based distributed Knowledge Base Profile (KBP) that provides local and global intelligence to make contextual and proactive handover decisions. We evaluated SIM-Know in an emulated wireless network. When the end-user device moves at low and moderate speeds, the results show that our approach outperforms the Signal Strong First (SSF, single criterion approach) and behaves similarly to the Analytic Hierarchy Process combined with the Technique for Order Preferences by Similarity to the Ideal Solution (AHP-TOPSIS, multicriteria approach) regarding the number of handovers and the number of throughput drops. SSF outperforms SIM-Know and AHP-TOPSIS regarding the handover latency metric because SSF runs a straightforward process for making handover decisions. At high speeds, SIM-Know outperforms SSF and AHP-TOPSIS regarding the number of handovers and the number of throughput drops and, further, improves the throughput, delay, jitter, and packet loss in the network. Considering the obtained results, we conclude that SIM-Know is a practical and attractive solution for cognitive HM.

Full textAbstract:
Femtocells are considered a technology to improve performance of a network by increasing network coverage and communication capacity at a relatively low cost. However, if there are a lot of femtocells in a macrocell, the number of handovers greatly increases, and unnecessary handovers can occur from the mobile station temporarily passing through a femtocell. In this paper, we propose a method that probabilistically estimates the path in a femtocell and makes a handover decision based on the available data capacity of a mobile station on the estimated path. Simulation results show that the proposed method effectively reduces the number of unnecessary handovers while improving the data rate and capacity.

Full textAbstract:
Purpose The purpose of this paper is to investigate the content, purpose and effectiveness of the handover of information between care home staff beginning and completing a shift. Design/methodology/approach This was an exploratory study drawing on ethnographic methods. A total of 27 interviews with a range of care home staff, including managers, registered nurses, senior care workers and care workers were undertaken in five care homes selected to give a good contrast in terms of size, ownership, shift patterns and type of handover. Findings Most handovers were short – lasting 15 min or so – and were held in the office or secluded area in which staff could talk privately. They lasted longer in one home in which the incoming and outgoing shifts physically visited each resident’s room and the communal spaces. Staff felt that handovers were important for the efficient running of the home as well as to alert everyone to changes in a resident’s health or important events, such as a hospital appointment. In one home, handheld devices enabled staff to follow a resident’s care plan and update what was happening in real time. Research limitations/implications This was a small scale study based on data from a limited number of care homes. Practical implications The increasing popularity of 12 h shifts means that many homes only hold two short handovers early in the morning and in the evening when the night staff arrive. There appears to be a trend to reduce the number of staff paid to attend handover. Despite this, handovers remain an important component of the routine of a care home. The information contained in handover relates to the running of the care home, as well as residents’ wellbeing, suggesting that, while their content overlaps with written records in the home, they are not superfluous. Originality/value Although the literature on handovers in hospitals is extensive, this appears to be the first published study of handover practices in care homes.

Currently patient safety continues to be a major concern for nurses. One of the activities that can have an impact on patient safety is handovers carried out by nurses. Data shows that medical and treatment errors can threaten patient safety, 70% of them because of non-optimal handover activities by nurses. However, there are several organizational factors that influence the success of handover activities by nurses. This research is a quantitative study with a correlational design. The population was all nurses in the inpatient room of the Hospital in Banda Aceh, with a total of 175 nurses. The instrument for measuring organizational factors was adopted from the Hospital Survey on Patient Safety from the U.S. Agency for Healthcare Research and Quality (AHRQ), Department of Health and Human Services. Then, the instrument developed by Arianti was used for measuring nurse handover. Data were analyzed by using Chi-Square test and binary logistic regression with stepwise method. The results showed that of the 3 organizational factor variables in patient safety, 2 variables namely enabling factor (P-value: 0.000) and enacting factor (P-value: 0.002) were significant predictors of nurse handover in the inpatient ward. Furthermore, the data analysis indicated enabling factor is the most dominant predictor of nurse handover, with an odds ratio (OR) of 116.999. Meanwhile, the elaborating factor did not significantly affect the handover of nurses in the inpatient ward. Organizational factors that influence the success of the handover of the nurse in the inpatient unit are enabling and enacting factors.

Full textAbstract:
This study addresses the handover management issue for Device-to-Device communication in fifth-generation (5G) networks. The Third Generation Partnership Project (3GPP) drafted a standard for proximity services (ProSe), also named device-to-device (D2D) communication, which is a promising technology in offering higher throughput and lower latency services to end users. Handover is an essential issue in wireless mobile networks due to the mobility of user equipment (UE). Specifically, we need to transfer an ongoing connection from an old E-UTRAN Node B (eNB) to a new one, so that the UE can retain its connectivity. In the data plane, both parties of a D2D pair can communicate directly with each other without the involvement of the base station. However, in the control plane, devices must be connected to the eNB for tasks such as power control and resource allocation. In the current standard of handover scheme, the number of unnecessary handovers would be increased by the effect of shadowing fading on two devices. More important, the handover mechanism for D2D pairs is not standardized yet. LTE-A only considers the handover procedure of a single user. Therefore, when a D2D pair moves across cell boundaries, the control channels of the two UEs may connect to different base stations and result in increased latency due to the exchange of D2D related control messages. Hence, we propose a handover management scheme for D2D communication to let both parties of a D2D pair handover to the same destination eNB at the same time. By doing so, the number of unnecessary handovers, as well as the handover latency, can be reduced. In the proposed method, we predict the destination eNB of D2D users based on their movements and the received signal characteristics. Subsequently, we make a handover decision for each D2D pair by jointly factoring in the signal quality and connection stability. Expected improvement can be attained, as revealed in the simulation. Unnecessary handover can be avoided. Consequently, both UEs of a D2D pair reside in the same cell and, therefore, result in increased throughput and decreased delay.

In the modern era of technology, the high speed internet is the most important part of human life. The current available network is reckoned to be slow in speed and not be up to snuff for data transmission regarding business applications. The objective of handover mechanism is to reassign the current session handle by internet gadget. The globe needs the next generation high mobility and throughput performance based internet model. This research paper explains the proposed method of design and development for handover based 5G cellular network. In comparison to the traditional method, we propose to control the handovers between base-stations using a concentric method. The channel simulator is applied over the range of the frequencies from 500 MHz to 150 GHz and radio frequency for the 700 MHz bandwidth. The performance of the simulation system is calculated on the basis of handover preparation and completion time regarding base station as well as number of users. From this experiment we achieve the 7.08 ms handover preparation time and 9.98 ms handover completion time. The author recommended the minimum handover completion time, perform the high speed for 5G cellular networks.

Full textAbstract:
A Hybrid LiFi and WiFi network (HLWNet) integrates the rapid data transmission capabilities of Light Fidelity (LiFi) with the extensive connectivity provided by Wireless Fidelity (WiFi), resulting in significant benefits for wireless data transmissions in the designated area. However, the challenge of decision-making during the handover process in HLWNet is made more complex due to the specific characteristics of electromagnetic signals’ line-of-sight transmission, resulting in a greater level of intricacy compared to previous heterogeneous networks. This research work addresses the problem of handover decisions in the Hybrid LiFi and WiFi networks and treats it as a binary classification problem. Consequently, it proposes a handover method based on a deep neural network (DNN). The comprehensive handover scheme incorporates two sets of neural networks (ANN and DNN) that utilize input factors such as channel quality and the mobility of users to enable informed decisions during handovers. Following training with labeled datasets, the neural-network-based handover approach achieves an accuracy rate exceeding 95%. A comparative analysis of the proposed scheme against the benchmark reveals that the proposed method considerably increases user throughput by approximately 18.58% to 38.5% while reducing the handover rate by approximately 55.21% to 67.15% compared to the benchmark artificial neural network (ANN); moreover, the proposed method demonstrates robustness in the face of variations in user mobility and channel conditions.

AimsPrimary: To improve the quality of medical handover by increasing trust-wide completion rate for agreed quality standards from baseline to 80% by July 2019To standardise the medical handover across all 5 boroughs within the trust by July 2019Secondary: To separately assess the completion rate for new patient checks in relation to baselineBackgroundNot only is there a recognised variation in the medical handover across Pennine care foundation trust's (PCFT) 5 boroughs (Tameside, Rochdale, Bury, Oldham and Stockport), but there also appears to be diminished adherence to quality standards to a varying extent. This was shown to result from a combination of human factors and process errors consequently leading to near-miss clinical incidents. This project was therefore designed to highlight and address these issues in order to promote patient safety.MethodHaving identified the problems and agreed on quality standards, baseline data were gathered through May 2019 with the primary outcome measure being the percentage completion rate for quality standards across all handovers. Changes were made to the handover document in June 2019 followed by introduction of a new handover document and post-intervention data collection through July 2019. Doctors’ satisfaction with the new handover document using a typical 5-level Likert scale was measured using a trust-wide online survey.ResultOur results showed a considerable Trust-wide improvement in the completion rate for agreed quality standards from 54% at pre-intervention to 77% at post-intervention with all 5 boroughs demonstrating improvement to varying extents. This is noted to be reasonably close to the project aim of improving the completion rate from baseline to 80%. With regards to new patient checks, there was a marginal Trust-wide increase in completion rate from 53% at pre-intervention to 56% at post-intervention. Additionally, the trust-wide online survey measuring doctors’ satisfaction with the new handover revealed a majority (82%), either strongly agreed (27.3%), or agreed (54.6%), that the new handover document has improved the overall quality of handovers.ConclusionTrust-wide standardisation of the handover has now presented the opportunity to benchmark boroughs within PCFT against one another in terms of adherence to quality standards and alignment with best practice relating to patient safety. While substantial improvement may have been made in the overall quality of handovers across the trust, the inter-borough disparity in the extent of improvement identified gaps for future follow-up or related projects.

Interprofessional communication is a process in planning, implementing and evaluating communication programs aimed at health service providers. Handover is the process of transferring the main authority and responsibility for providing clinical care to patients from one nurse to another. The implementation of the SBAR Handover and interprofessional communication was not optimal, decreasing from 98% in January-March to 95% in July-August. This research is to determine the relationship between the implementation of the SBAR handover and the interprofessional communication of nurses at the Tanjungpinang City Hospital in 2023. This research is a quantitative research using an analytical survey. The total population was 150 respondents. The sample in this study was 60 respondents. The sampling technique is non-probability sampling with purposive sampling technique. The data analysis used was the Chi-square test with a significance of 0.05. There is a relationship between SBAR handover and interprofessional communication between nurses at Tanjungpinang City Regional Hospital. Implementing good SBAR handovers and good interprofessional communication between nurses has a big influence in optimizing the provision of nursing care and improving the quality of service in hospitals. It is hoped that nurses will further improve solid collaboration when working through the implementation of SBAR handovers and interprofessional communication in accordance with standards.

Full textAbstract:
The 5G core network adopts a Control and User Plane Separation (CUPS) architecture to meet the challenges of low-latency business requirements. In this architecture, a balance between management costs and User Experience (UE) is achieved by moving User Plane Function (UPF) to the edge of the network. However, cross-UPF handover during communication between the UE and the remote server will cause TCP/IP session interruption and affect continuity of delay-sensitive real-time communication continuity. Information-Centric Networks (ICNs) separate identity and location, and their ability to route based on identity can effectively handle mobility. Therefore, based on the 5G-ICN architecture, we propose a seamless mobility support method based on router buffered data (BDMM), making full use of the ICN’s identity-based routing capabilities to solve the problem of UE cross-UPF handover affecting business continuity. BDMM also uses the ICN router data buffering capabilities to reduce packet loss during handovers. We design a dynamic buffer resource allocation strategy (DBRAS) that can adjust the buffer resource allocation results in time according to network traffic changes and business types to solve the problem of unreasonable buffer resource allocation. Finally, experimental results show that our method outperforms other methods in terms of average packet delay, weighted average packet loss rate, and network overhead. In addition, our method also has good performance in average handover delay.

This study aims to determine the factors associated with proactive behavior in the handover process in the intensive care unit of RSUD Aceh. The method used is a cross-sectional study. Data were analyzed using chi-square and logistic regression analysis with the Backward stepwise test. The results showed that 100 out of 124 respondents were in the category of strong proactive behavior. The results of the chi-square test showed that proactive personality (p-value 0.041), self-efficacy (p-value 0.002) and learning orientation (p-value 0.013) had a relationship with nurses' proactive attitude in carrying out handovers. The results of the logistic regression test showed that the most dominant factor related to the proactive behavior of nurses in carrying out handovers was self-efficacy, with a significance value of 0.020 and an odds ratio of 5.419. In conclusion, self-efficacy is the most significant factor related to the proactive behavior of nurses in the handover process in the intensive care unit of the Aceh General Hospital.

Clinical handovers from out-of-hours activity are essential for relaying information about events such as new admissions, outstanding or complete investigations, physical health reviews, ward jobs and risk. This information enables the day team to effectively prioritise and follow-up any necessary tasks.Junior doctors at a hospital site in the London Borough of Newham were aware that the existing handover system, constituted of a word document circulated via email, was lacking robustness and that the handover was not sent out reliably on a daily basis.Quality improvement (QI) methods including process mapping, PDSA ('Plan, Do, Study, Act') cycles, driver diagrams and run charts were used to understand the issue, create a more robust process and measure the improvements made, all supported by regular QI project meetings. The change ideas included moving from an informal Microsoft (MS) Word document, which was emailed out, to an Excel spreadsheet stored centrally on MS Teams. Column headers were added for admissions, ward jobs, seclusion reviews, matters relating to mental health law and Accident and Emergency (A&E) assessments, as well as defined columns for outstanding jobs and standard tasks that need to be completed for all admissions. Responsibility for circulating the handover list was given to the incoming day duty doctor if the night doctor was too busy, with admin support to chase the circulation of the handover. Results were studied for the following 18 months.The percentage of handovers being appropriately sent out increased from a median of 80% to 100% during the project period, and the availability of handover data where the data were visible to doctors on MS Teams but had not been sent out also increased from a median of 80% to 100%. The system was deemed safe, effective and easy to use, and has already been replicated at neighbouring hospitals.

Abstract Background Communication failures are a key cause of medical errors and are particularly prevalent during handovers of patients between services. Objective To explore current perceptions of effectiveness in communicating critical patient information during admission handovers between emergency medicine (EM) residents and internal medicine (IM) residents. Methods Study design was a survey of IM and EM residents at a large urban hospital. Residents were surveyed about whether critical information was communicated during patient handovers. Measurements included comparisons between IM and EM residents about their perceptions of effective communication of key patient information and the quality of handovers. Results Ninety-three percent of EM residents (50 of 54) and 80% of IM residents (74 of 93) responded to the survey. The EM residents judged their handover performance to be better than how their IM colleagues assessed them on most questions. The IM residents reported that one-half of the time, EM residents provided organized and clear information, whereas EM residents self-reported that they did so most of the time (80%–90%). The IM residents reported that 25% of handovers were suboptimal and resulted in admission to an inappropriate level of care, and 10% led to harm or delay in care. The EM residents reported suboptimal communication was less common (5%). On the global assessment of whether the admission handover provided the information needed for good patient care, IM residents rated the quality of the handover data lower than did responding EM residents. Conclusions There are gaps in communicating critical patient information during admission handovers as perceived by EM and IM residents. This information can form the basis for efforts to improve these handovers.

AimsTo achieve 100% of digital handover records being completed by doctors at end of shifts in Holywell Hospital, Northern Ireland.MethodsTransition to completion of digital handover record began in 2019. This was initially audited during 2020-2021 with slowly worsening results. After this, audit data were no longer recorded.Since becoming trainee representative in February 2022, I investigated, along with my colleagues, reasons as to why this was not being completed nor being achieved. Reasons established included unaware of necessity, chronic culture of not being completed, a lack of access to shared drive and outside locums covering shifts as well as a higher percentage of doctors who were on shorter 4 month rotations. Literature review around junior doctor handovers in other sites was also completed and analysed.A Plan Do Study Act (PDSA) cycle was subsequently established taking these factors into account from August 2022 to January 2023 with a focus on information sharing, training at specific junior doctor changeover points, liaising with administration to ensure adequate access to handover and regular audit and feedback amongst junior doctors.ResultsFrom a new baseline of 5.36% of digital handovers being completed in February 2022 there has initially been a gradual increase noted at April 2022 to (35.00%) remaining relatively static into August 2022 (25.81%). Some of this related to doctors not having requisite access to shared folder.However, percentage completed increased substantially after August 2022 with better administrative support and from September 2022 (70.00%) to December 2022 (88.71%) and into January 2023 (91.94%) handovers were completed.ConclusionThrough a combination of better information sharing amongst junior doctors, signposting to digital handover, improvement of early access to requisite folder and specific teaching regarding handover at induction at all changeovers, stressing importance of completion from clinical governance perspective, there has been a genuine sea-change amongst junior medical staff that has included taking better ownership of the process and shared responsibility for it being completed.This record-keeping improvement has been stark and maintained for a prolonged period, particularly from September 2022 and is now averaging over 90% being completed. There remains some issues regarding access if shift being covered by an outside locum doctor and this would be next targeted area with the goal of achieving 100% record of digital handover occurring.

Full textAbstract:
BackgroundAmbulance handover delays are an important indicator of an emergency care system under pressure. Delayed handovers compromise patient safety in the Emergency Department (ED). As a direct consequence patients wait longer for an emergency ambulance response, and as a result patient safety in the community is also compromised. We explored factors perceived to contribute to ambulance handover delays at EDs in an urban area of England, in order to inform delay reduction strategies.MethodsFifteen EDs were visited as part of a regional improvement programme. Ambulance handover processes were observed, and staff involved in the process were informally interviewed. A data corpus of twenty-nine written reports was generated. These reports were anonymised and thematic analysis was used inductively to explore the phenomenon of ambulance handover delay. Pattern coding was used to identify and cluster common themes, with magnitude coding added to identify the most prevalent themes.ResultsPerceived reasons for ambulance handover delay arose from a number of factors. A mismatch was frequently seen between handover capacity and demand. This occurred alongside, but was also frequently observed to be independent of, ED exit block. Approaches to escalation were often sub-optimal. This was observed both before and after an ambulance queue developed. Processes were often uneconomical by design, and pathways were frequently inefficient. Inter-professional culture was identified as an important, cross-cutting theme, with a lack of urgency to release ambulances frequently observed.ConclusionsOur results suggest several factors influence ambulance handover delays. Programmes which aim to improve overall hospital flow, streamline pathways and processes, and improve escalation are needed. Programmes should also seek to improve the inter-professional culture relating to ambulance handover. Limitations to this enquiry include an opportunistic, retrospective approach and use of a convenience sample. There are few empirical studies which address the causes of ambulance handover delay. More research is needed on this important patient safety issue.

Full textAbstract:
Background Ineffective communication procedures create openings for errors when health care professionals fail to transfer complete, consistent information. Deficient or absent clinical handovers, or failures to transfer information, responsibility, and accountability, can have severe consequences for hospitalized patients. Clinical handovers are practiced every day, in many ways, in all institutional health care settings. Objective This study aimed to design an evidence-based, nursing handover standard for inpatients for use at shift changes or internal transfers between hospital wards. Methods We carried out a modified, multiround, web-based, Delphi data collection survey of an anonymized panel sample of 264 nurse experts working at a multisite public hospital in Switzerland. Each survey round was built on responses from the previous one. The surveys ended with a focus group discussion consisting of a randomly selected panel of participants to explain why items for the evidence-based clinical nursing handover standard were selected or not selected. Items had to achieve a consensus of ≥70% for selection and inclusion. Results The study presents the items selected by consensus for an evidence-based nursing handover standard for inpatients for use at shift changes or internal transfers. It also presents the reasons why survey items were or were not included. Conclusions This modified Delphi survey method enabled us to develop a consensus- and evidence-based nursing handover standard now being trialed at shift changes and the internal transfers of inpatients at our multisite public hospital in Switzerland.

Background: The SBAR (situation, background, assessment, recommendation) method assists nurses in communicating information in nursing shift handover. Inaccurate shift handover can have a serious impact on patients due to poor communication. Optimal resource development can be done by coaching as the best guidance method from manager for directional discussion and guidance activity to learn to solve problem or do better job and build nursing leadership culture in clinical service.Objective: To analyze the effectiveness of coaching method using SBAR communication tool on nursing shift handovers.Methods: This was quasy experimental study with pretest posttest control group design. Fifty-four nurses were selected using consecutive sampling, which 27 assigned in the experiment and control group. An observation checklist was developed by the researchers based on the theory of Lardner to evaluate the effectiveness of the implementation of coaching using SBAR on nursing shift handover. Independent t-test, Mann-Whitney test and Wilcoxon test were used for data analyses. Results: There was an increase in coaching ability of head nurses in the implementation of SBAR in nursing handover after 2-weeks and 4-weeks of coaching. And there was also a significant improvement of the use of SBAR on nursing shift handover in the experiment group (p <0.05) compared to the control group. Conclusion: coaching using SBAR (situation, background, assessment, recommendation) communication tool was effective on nursing shift handovers. There was a significant increase of the capability of head nurse and nursing shift handover after coaching intervention.

Context and objectiveThe negative consequences of inadequate nursing handovers on patient safety are widely acknowledged, both within the literature as in practice. Evidence regarding strategies to improve nursing handover is, however, lacking. This study investigates the effect of a tailored, blended curriculum on nurses’ perception of handover quality.MethodsWe used a pre-test/post-test design within four units of a Belgian general hospital. Our educational intervention consisted of an e-learning module on professional communication and a face-to-face session on the use of a structured method for handovers. All nurses completed this blended curriculum (n=87). We used the Handover Evaluation Scale (HES) to evaluate nurses’ perception of handover quality before and after the intervention. The HES was answered by 87.4% of the nurses (n=76 of 87) before and 50.6% (n=44 of 87) after the intervention. Confirmatory factor analysis was used to assess the validity of the HES.ResultsThe original factor structure did not fit with our data. We identified a new HES structure with acceptable or good fit indices. The overall internal consistency of our HES structure was considered adequate. Perception of nurses on Relevance of information showed a significant improvement (M=53.19±4.33 vs M=61.03±6.01; p=0.04). Nurses also felt that the timely provision of patient information improved significantly (M=4.50±0.34 vs M=5.16±0.40; p=0.01).ConclusionThe applied intervention resulted in an improved awareness on the importance of Relevance of information during handovers. After our intervention, the nurses’ perception of the HES item ‘Patient information is provided in a timely manner’ also improved significantly. We are aware that the educational intervention is only the first step to achieve the long-term implementation of a culture of professional communication based on mutual support.

The poor coverage problem inside the buildings and the existence of disparate wireless technologies have led to the development of integrated macro femtocellular networks. Correct and efficient vertical handover decision is of utmost importance in such integrated macro femtocellular networks. Initially, Received Signal Strength (RSS) used to be the sole criterion for taking a decision for vertical handover. Such decision leads to inaccurate results and therefore unnecessary handovers. In this paper, a multicriteria vertical handover strategy based on received signal strength, user velocity, number of users in a cell and data rate of the cell is proposed. This proposed strategy and the traditional algorithm are simulated and the results are analyzed quantitatively for different QoS parameters namely ping pong rate, packet loss ratio, throughput, packet delay, jitter and signalling cost. The results show significant improvement in the QoS parameters when the proposed strategy is used as compared to traditional algorithm.

Full textAbstract:
With the use of collaborative robots in intelligent manufacturing, human–robot interaction has become more important in human–robot collaborations. Human–robot handover has a huge impact on human–robot interaction. For current research on human–robot handover, special attention is paid to robot path planning and motion control during the handover process; seldom is research focused on human handover intentions. However, enabling robots to predict human handover intentions is important for improving the efficiency of object handover. To enable robots to predict human handover intentions, a novel human handover intention prediction approach was proposed in this study. In the proposed approach, a wearable data glove and fuzzy rules are firstly used to achieve faster and accurate human handover intention sensing (HIS) and human handover intention prediction (HIP). This approach mainly includes human handover intention sensing (HIS) and human handover intention prediction (HIP). For human HIS, we employ wearable data gloves to sense human handover intention information. Compared with vision-based and physical contact-based sensing, wearable data glove-based sensing cannot be affected by visual occlusion and does not pose threats to human safety. For human HIP, we propose a fast handover intention prediction method based on fuzzy rules. Using this method, the robot can efficiently predict human handover intentions based on the sensing data obtained by the data glove. The experimental results demonstrate the advantages and efficacy of the proposed method in human intention prediction during human–robot handover.

Handovers on 4G networks such as Hard Handover when downlink and uplink must run well, if not then ongoing downlinks and uplinks will be hampered and even fail. This is closely related to potential customer satisfaction, thus the possibility of a handover failure resulting in dissatisfaction with operator users. Along with the high customer interest in 4G-LTE technology, this makes Telkomsel cellular operators maintain Quality & Performance where there is a decline in the quality of RSRP & SINR. One effort is to measure data in the field. The method in measuring data in the field is a Test Drive. Test Drive is a measurement method in a mobile communication system that aims to collect data on the measurement of signal quality of a network from the real direction in the field, so that it can know how the performance of the network.

<p>One of the most attractive and challenging areas in the upcoming next-generation 5G wirelessnetworkistheverticalhandover(VHO).Recently,manyoftheheterogeneous wireless communication technologies are introduced to satisfy the demands of users in all situations. Due to the deployment of heterogeneous networks, the users can access the internet anywhere, anytime through different wireless networks. To obtain seamless service and service continuity, the device should be handed over to the best wireless networks. Here, a half handover scheme for Device-to-Device (D2D) communication is implemented for the selection of the best network. The target network selection for vertical handover can be handled using multiple attribute decision making (MADM) methods. An intelligent and fast vertical handover decision is much needed, which should be reliable even for random and uncertain environments. Fuzzy logic is proved to be effective in handling imprecise data.

Constantly faster, mobile terminals are developing, as well as wireless networks, to satisfy the growth of “Always Best Connected” demand. Users nowadays want to access the best available wireless network, either from 3GPP or IEEE group technologies, wherever they are, without losing their sessions. Consequently, mobile terminals must seamlessly transfer the communications to another access technology (vertical handover) if needed, as they often move into heterogeneous wireless environments. This work aims to optimize the network selection step in the vertical handover process. Multiattribute Decision-Making methods naturally fit this context. Nevertheless, they make wrong handover decisions sometimes, due to imprecise data collected from the metrics. This manuscript presents the use of a hybrid method, combining the fuzzy technique for order preference by similarity to the ideal situation and fuzzy analytic network process, in the network selection, to improve the quality of service and avoid, as much as possible, unnecessary handovers. The results demonstrate that this combination is the best, compared to the other methods of the same type in the network selection context.
