Abstract:

Similar to the manufacturing sector, process improvement gains much attention in health care sector. Measuring process quality is one of the most important components of process improvement and numerous healthcare quality indicator models are developed to achieve this aim. Existing quality models focus on some specific diseases, clinics or clinical areas. Although they contain structure, process, or output type measures, there is no model which measures the quality of health care processes comprehensively. As a result, hospitals cannot compare quality of processes internally and externally. To bring a solution to the above problems, we developed Health Care Process Quality Measurement Model (HPQMM), and it is applied in three public hospital&rsquo
s laboratory and assessment processes. We observed that, the developed model determines weak and strong aspects of the processes, gives a detailed picture for the process quality, extends the quality aspects of existing models, and provides quantifiable information to hospitals to compare their processes with multiple organizations.

Abstract:

Presently, self-tracking applications are used to help patients with chronic illness management. For example, applications ask users to track mood through online diaries or snap photos of their food content in order to analyze patterns correlated to their chronic disease. Although these health care applications are on the market today, there still exists a fundamental challenge in motivating participants to consistently update and enter information. Therefore, the focus of this thesis is on reducing the fatigue from using these applications. Pulling from user social media data will almost completely eliminate the capture burden placed on participants, since users will only have to continue to use social media as they regularly do. Instead of analyzing manually inputted data, patterns can be found between social media data and chronic diseases. A Microsoft Research team found indicators in public user Twitter data associated with the onset of a depressive episode. They were able to create a predictor tool, predicting the onset of a depressive episode, with 70 percent accuracy. Using this research alongside expert feedback, our aim is to design an interface used by both clinician and patient that will provide them with a timeline marking spikes in Twitter indicators correlated to a patient’s depressive episode.

Abstract:

Technology plays an increasingly important role in modern health care. This thesis presents an approach to usability evaluation of mobile information and communications technologies designed for diabetes patients&rsquo
use in their daily lives. According to our study conducted on 60 diabetes patients, several important findings were obtained. Fifty nine (98.3%) diabetes patients were highly satisfied with the mobile health technology and expressed that they would use it, and found the measured values reliable. For 57 (95%) diabetes patients
measuring, checking and accessing the blood glucose level easily anytime and anywhere were very important. Fifty six (93.3%) said that they would wish to send their blood glucose levels to their physicians via e-mail. When participants were asked to provide a decision on future health care, predominate number of participants said they would change their lifestyle rather than visit a doctor regardless of their blood glucose level. In conclusion, little is known about such effects of mobile information and communications technologies in self-management care situations. It is clear that usability studies in the field are more difficult to conduct than laboratory evaluations. Further studies with larger sample sizes are needed to further evaluate these initial findings.

Abstract:

The healthcare application domain has potential for research in the computer science field and Android domain. The built-in sensors and interfaces for virtual reality plugged in to the Android platform makes it a viable option for developers and end users. The B-Activ Android application builds a platform, which unlike other healthcare applications, ensures that the user is provided with essential input to indulge in an active life. External factors such as climate, pollution levels in the vicinity, and the user’s Body Mass Index (BMI) affect a person’s involvement in exercise and are central to the B-Activ application. B-Activ allows users to interact through traffic and pollution updates with people in the same city. The scope of B-Activ is to ensure that the user is active enough through simple exercises in order to control the cholesterol level and obesity thereby reducing the chances of deadly diseases.

Brownbridge, Garry. "Doctor-patient communication and the consulting room use of computers in general practice." Thesis, University of Sheffield, 1988. http://etheses.whiterose.ac.uk/3532/.

Abstract:

This thesis examines the effects of general practitioners' use of a computer during consultations, on doctor-patlent communication and the delivery of care. The IBM Sheffield Primary Care System was used by GPs during routine consultations for the review and update of patients' records. The system also provided an interactive protocol for the management of patients with chronic hypertension. Video recordings were made of over 800 consultations with and without use of the computer. These were used to identify a comprehensive and reliable set of measures of doctor-patient communication. With medical collaboration measures of the standard of delivery of care were also developed. The measures were then used to investigate the effects of computer use. When used for the review and update of records the computer had little effect on doctor-patient communication. Doctors showed more solidarity with patients (e. g. by offering supportive comments), but there was no effect on the amount of information and advice offered or questions asked by either doctor or patient. However, overall, there was a slight impairment of the doctor's interpersonal manner and delivery of care. When the computer was used in direct support of clinical decision-making (i. e. through the hypertension management protocol) there was a marked improvement in the doctors’ clinical performance in terms of the number of relevant verbal and physical examinations conducted and recorded. The findings suggest ways in which future systems should be designed and used to avoid possible adverse consequences for doctor-patient communications. A research framework, including new methodologies, is also offered for the evaluation of future consulting room systems. Similar evaluative studies need to be performed on the more sophisticated systems now available, especially the clinically oriented ones which offer most potential.

Abstract:

Not much has changed for the migrant farmworker in the last thirty years. In one of the wealthiest countries on earth, migrant farmworker health status remains comparable to that found in Third World countries because of poor sanitation, poor nutrition and exposure. Current estimates show that migrant clinics are serving less than 20% of this population, leaving about 2,000,000 farmworkers without medical care. The barriers to health care for this population are numerous. This study will focus on the barrier to care resulting from lack of continuity in care due to poor inter-clinic communication. In this study it has been shown that computer disks and a standard word-processing program can be used to create a portable medical health history for the migrant to improve inter-clinic communication. In the process of carrying out this study, it was also shown how other barriers to care for this vulnerable population might be removed as well.

Abstract:

This report describes the development process of the mobile application HealthyWay. The application is developed as a Bachelor thesis project together with KTH Royal Institute of Technology. The applications' main function is to be the interface to a number of wearable medical electronic appliances such as bandages and pill boxes. The communication is done through Bluetooth Low Energy. The application was mainly written in 3 di erent languages, QML, C++ and Java. The most stressed point throughout this project was the importance of platform independence. The exibility had to be done on a scalable as well as on a modular level. With this in mind, QT was used to address the requirement of scalability. The modularity was achieved through an organized structure to the program accompanied by easy directives to introduce new devices. The purpose of the application is to increase the quality of life for the user. This intent could however not be concluded due to the lack of testing among users. In its current state, the application is not yet ready for deployment but instead acts as a framework for future prospects.
Den här rapporten beskriver utvecklingsprocessen för en mobilapplikation vid namn Healthy- Way. Applikationen är utvecklad som ett kandidatexamensarbete tillsammans med KTH. Applikationens huvudsakliga uppgift är att vara ett gränssnitt till medicinskt relaterad utrustning såsom plaster och pilleraskar. Kommunikationen mellan dessa sker via Bluetooth Low Energy. Applikationen skrevs huvudsakligen i 3 olika språk, QML, C++ och Java. Den viktigaste punkten genom projektets gång var att applikationen skulle vara oberoende av plattform. Flexibiliteten var tvungen att göras på både en skalbar och modulär nivå. Med detta i åtanke valdes QT för att behandla skalbarheten. Modulariteten uppnåddes genom en välplanerad struktur på programmet tillsammans med instruktioner på hur ny utrustning kan introduceras. Syftet med programmet är att öka livskvaliteten för användaren. Detta syfte kunde däremot inte slutföras på grund av bristande testning hos användare. I dagens läge är applikationen inte redo för att släppas kommersiellt, men tjänar som ett bra ramverk för framtida utveckling.

Abstract:

Treatment of elderly people and citizens in need of professional care is one of the most important aspects of any society to consider that aims at support for quality of life. Support for such qualitative aspects of a modern society often manifests itself by means of value-chains. However, all activities that a business or organization uses are not included in the value-chain, it is only the activities and information that generate any kind of value for the users in a particular organization that are included in the value-chains. To that end, the locality of health care related information primarily exists at the hospital and, therefore, the care of patients is most efficiently carried out at the hospital. However, if the involved information can be accessed anywhere throughout the value-chain, a possible situation would be to keep the patients in their homes without disrupting already established work practice and related value-chains. In principle, introducing new technology must not disrupt a value-chain; it must preserve or, even better, improve it. Health care is becoming more mobile and needs support for such behavior. The quantitative value to the user is quantified by means of value-chains, so it is important that they remain non-disrupted. Consequently, the fundamental concepts dealt with in this thesis are; value-chains, health care and mobile technology. The problem domain is distributed health care and we have chosen to focus on sustainability of the involved value-chains. In essence, we want to add new technology to the domain without disrupting already existing value-chains. This in order to make the distributed health care apparatus more efficient and cost effective. The main problem we have identified is regarding how medical doctors and nurses could access the same information in patients' homes as they can at the hospital.

Zhang, Peng. "Multi-agent Systems in Diabetic Health Care." Licentiate thesis, Karlskrona : Blekinge Institute of Technology, 2005. http://urn.kb.se/resolve?urn=urn:nbn:se:bth-00263.

Full text

Abstract:

This thesis discusses how Multi-agent Systems (MAS) should be designed in the context of diabetic health care. Three fields are touched: computer science, socio-psychology and systems science. Agent Technology is the core technology in the research. Theories from socio-psychology and systems science are applied to facilitate the discussion about computer agents. As the integration of socio-psychology and systems science, Activity Systems Theory is introduced to give a synthesized description of MAS. Laws and models are introduced with benefits on both individual agent and agent communities. Cybernetics from systems science and knowledge engineering from computer science are introduced to approach the design and implementation of the individual agent architecture. A computer agent is considered intelligent if it is capable of reactivity, proactivity and social activity. Reactivity and proactivity can be realized through a cybernetic approach. Social activity is much more complex, since it considers MAS coordination. In this thesis, I discuss it from the perspectives of socio-psychology. The hierarchy and motivation thinking from Activity Systems Theory is introduced to the MAS coordination. To behave intelligent, computer agents should work with knowledge. Knowledge is considered as a run-time property of a group of agents (MAS). During the MAS coordination, agents generate new information through exchanging the information they have. A knowledge component is needed in agent’s architecture for the knowledge related tasks. In my research, I adopt CommonKADS methodology for the design and implementation of agent’s knowledge component. The contribution of this research is twofold: first, MAS coordination is described with perspectives from socio-psychology. According to Activity Systems Theory, MAS is hierarchically organized and driven by the motivation. This thesis introduces a motivation-driven mechanism for the MAS coordination. Second, the research project Integrated Mobile Information Systems for health care (IMIS) indicates that the diabetic health care can be improved by introducing agent-based services to the care-providers and care-receivers. IMIS agents are designed with capabilities of information sharing, organization coordination and task delegation. To perform these tasks, the IMIS agents interact with each other based on the coordination mechanism that is discussed above.

Abstract:

This dissertation deals with three problems in health care. In the first, we consider the incentives to change prices and capital levels at hospitals, using optimal control under the assumption that private payers charge higher prices if patients consume more hospital services. The main results are that even with fixed technology, investment and prices exhibit explosive growth, and that prices and capital stock grow in proportion to one another. In the second chapter, we study the flow of nosocomial infections in an intensive care unit. We use data from Cook County Hospital, along with numerous results from the literature, to construct a discrete event simulation. This model highlights emergent properties from treating the flow of patients and pathogens in one interconnected system, and sheds light on how nosocomial infections relate to hospital costs. We find that the system is not decomposable to individual systems, exhibiting behavior that would be difficult to explain in isolation. In the third chapter, we analyze a proposed change in diversion policies at hospitals, in order to increase the number of patients served, without an increase in resources. Overcrowding in hospital emergency departments is caused in part by the inability to send patients to main hospital wards, due to limited capacity. When a hospital is completely full, the hospital often goes on ambulance diversion, until some spare capacity has opened up. Diversion is costly, and often leads to waves of diversions in systems of hospitals, a situation that is regarded as highly problematic in public health. We construct and analyze a continuous-time Markov chain model for one hospital. The intuition behind the model is that load-balancing between various hospitals in a metro area may hinder full congestion. We find that a more flexible contract may benefit all parties, through the partial diversion of federally insured patients, when a hospital is very close to full. Discrete event simulation models are run to assess the effect, using data from DeKalb Medical Center, and also to show that in a two-hospital system, more federally insured patients are served using this mechanism.

Abstract:

There is a growing interest within organisations today to focus on the core processes, i.e. the processes that create value for the intended customer, in order to stay compatible within the ever-fiercer competition. To have full control of the key processes may be a great step forward towards a more lean and effective organisation, not only for profit seeking companies but also for public welfare institutions like health care. Software aimed at supporting a process focus is continuously being developed and one such family of programs is commonly referred to as process managers.

A process manager lets the people in an organisation who have complete knowledge of the processes model these without requiring them to have expert knowledge of computers and programming. Once a process has been defined graphically according to a predefined modelling language, it can be deployed and monitored. The process manager software takes care of the routing of messages between actors, both human as well as non-human (e.g. other applications), and it drives the individual errand forward according to how the process flow has been defined in the model. However, applying a process manager approach in health care processes requires a certain amount of caution. Messages sent between actors in health care organisations are often of a delicate nature since they may contain sensitive information, such as illness, mental state, family situation and similar, that is related to an identifiable individual. There are also other aspects of security that need to be addressed besides the confidentiality aspect. For example, it must be guaranteed that the information is correct and not altered during transfer, the information must be available when needed and it should be possible to trace a message to its sender, among other things.

This work identifies a set of security requirements from the literature that need to be fulfilled in health care organisations when applying a process manager approach. With these requirements as a basis, a process manager system is evaluated with regards to security and the conclusion is that future versions need improvement on some points. Future work is also suggested that could help to explore the area further.

Full text

Abstract:

Patient data in health care have traditionally been used to support direct patient care. Although there is great potential in combining such data with genetic information from patients to improve diagnosis and therapy decisions (i.e. personalized medicine) and in secondary uses such as data mining, this is complex to realize due to technical, commercial and legal issues related with combining and refining patient data. Clinical decision support systems (CDSS) are great catalysts for enabling evidence-based medicine in clinical practice. Although patient data can be the base for CDSS logic, it is often scattered among heterogenous data sources (even in different health care centers). Data integration and subsequent data mining must consider codification of patient data with terminology systems in addition to legal and ethical aspects of using such data. Although computerization of the patient record systems has been underway for a long time, some data is still unstructured. Investigation regarding the feasibility of using electronic patient records (EPR) as data sources for data mining is therefore important. Association rules can be used as a base for CDSS development. Logic representation affect the usability of the systems and the possibility of providing explanations of the generated advice. Several properties of these rules are relatively easy to explain (such as support and confidence), which in itself can improve end-user confidence in advice from CDSS. Information from information sources other than the EPR can also be important for diagnosis and/or treatment decisions. Drug prescription is a process that is particularly dependent on reliable information regarding, among other things, drug-drug interactions which can have serious effects. CDSS and other information systems are not useful unless they are available at the time and location of patient care. This motivates using mobile devices for CDSS. Information structures of interactions affect representation in informatics systems. These structures can be represented using a category theory based implementation of rough sets (rough monads). Development of guidelines and CDSS can be based on existing guidelines with connections to external information systems that validate advice given the particular patient situation (for example, previously prescribed drugs may interact with recommended drugs by CDSS). Rules for CDSS can also be generated directly from patient data but this assumes that such data is structured and representative. Although there is great potential in CDSS to improve the quality and efficiency of health care, these systems must be properly integrated with existing processes in health care (workflows) and with other information systems. Health care workflows manage physical resources such as patients and doctors and can help to standardize care processes and support management decisions through workflow simulation. Such simulations allow information bottle-necks or insufficient resources (equipment, personnel) to be identified. As personalized medicine using genetic information of patients become economically feasible, computational requirements increase. In this sense, distributing computations through web services and system-oriented workflows can complement human-oriented workflows. Issues related to dynamic service discovery, semantic annotations of data, service inputs/outputs affect the feasibility of system-oriented workflow construction and sharing. Additionally, sharing of system-oriented workflows increase the possibilities of peer-review and workflow re-usage.

Abstract:

Primary health care is facing extensive changes due to digitalization, while the field of application for machine learning is expanding. The merging of these two fields could result in a range of outcomes, one of them being an improved and more rigorous adoption of clinical decision support systems. Clinical decision support systems have been around for a long time but are still not fully adopted in primary health care due to insufficient performance and interpretation. Clinical decision support systems have a range of supportive functions to assist the clinician during decision making, where one of the most researched topics is diagnostic support. This thesis investigates how the use of self-described anamnesis in the form of free text and multiple-choice questions performs in prediction of diagnostic outcome. The chosen approach is to compare text to different subsets of multiple-choice questions for diagnostic prediction on a range of classification methods. The results indicate that text data holds a substantial amount of information, and that the multiple-choice questions used in this study are of varying quality, yet suboptimal compared to text data. The over-all tendency is that Support Vector Machines perform well on text classification and that Random Forests and Naive Bayes have equal performance to Support Vector Machines on multiple-choice questions.
Primärvården förväntas genomgå en utbredd digitalisering under de kommande åren, samtidigt som maskininlärning får utökade tillämpningsområden. Sammanslagningen av dessa två fält möjliggör en mängd förbättrade tekniker, varav en vore ett förbättrat och mer rigoröst anammande av kliniska beslutsstödsystem. Det har länge funnits varianter av kliniska beslutsstödsystem, men de har ännu inte lyckats blivit fullständigt inkorporerade i primärvården, framför allt på̊ grund av bristfällig prestanda och förmåga till tolkning. Kliniskt beslutstöd erbjuder en mängd funktioner för läkare vid beslutsfattning, där ett av de mest uppmärksammade fälten inom forskningen är support vid diagnosticering. Denna uppsats ämnar att undersöka hur självbeskriven anamnes i form av fritext och flervalsfrågor presterar för förutsägning av diagnos. Det valda tillvägagångssättet har varit att jämföra text med olika delmängder av flervalsfrågor med hjälp av en mängd metoder för klassificering. Resultaten indikerar att textdatan innehåller en avsevärt större mängd information än flervalsfrågorna, samt att flervalsfrågorna som har använts i denna studie är av varierande kvalité, men generellt sett suboptimala vad gäller prestanda i jämförelse med textdatan. Den generella tendensen är att Support Vector Machines presterar bra för klassificering med text data medan Random Forests och Naive Bayes är likvärdiga alternativ till Support Vector Machines för predicering vid användning av flervalsfrågor.

Abstract:

This report is aimed at those who are interested in data analysis and data blending. Decision making is crucial for an organization to succeed in today’s market. Data analysis is an important support activity in decision making and is applied in many industries, for example healthcare. For many years data analysts have worked on structured data in small volumes, with traditional methods such as spreadsheet. As new data sources emerged, such as social media, data is generated in higher volume, velocity and variety [1]. The traditional methods data analysts apply are no longer capable of handling this situation. Hence scientists and engineers have developed a new technology called data blending. Data blending is the process of merging, sorting, joining and combining all the useful data into a functional dataset [2]. Some of the well-known data blending platforms include Datawatch, Microsoft Power Query for Excel, IBM DataWorks and Alteryx [3]. Synergus AB is a consulting company engaged in health economics, market access and Health Technology Assessment (HTA) [4]. The company does analysis for their clients. Unfortunately the way they work is not efficient. New tools and methods need to be applied in the company. The company has decided to apply data blending in their daily work. My task in this project was to build datasets for analysis and create workflows for future use with a data blending platform. For my interest, I did a research on data blending to understand how this new technology works. During the project I have worked with four data sources. These were Microsoft Excel worksheet, CSV file, MS Access database and JSON file. I built datasets the company needs. I also preceded a case study on data blending process. I focused on the three steps of data handling, namely input, process and output. After the project, I reached a conclusion that data blending offers better performance and functionality. It is easy to learn and use, too.
Denna rapport vänder sig till de som är intresserad av data analys och datahantering. Belsut fattande är avgörande för en organisation att lyckas i dagens marknad. Data analys är en viktig stöd inom beslutfattande och tillämpas i många industrier, till exempel hälsovård. I många år har data analyster arbetat med strukturerad data i små volymer, med traditionella arbetsmetoder såsom kalkyblad. Med nya data källor uppstått, såsom sociala media, data är genererad i högre volym, högre hastighet och högre variation. De traditionella metoder data analyster använder är inte längre kapabla av att hantera denna situation. Därför har vetenskapsmän och ingenjörer utvecklat ett ny teknologi kallad datahantering. Datahantering är en process för att sammanfoga, sortera och kombinera all värdeful data till en funktionell dataset. Några av de välkända datahanteringsplatformer inkluderar Datawatch, Microsoft Power Query for Excel, IBM DataWorks and Alteryx. Synergus AB är ett konsultföretag engagerad inom hälsoekonomi, marknad tillträde, och Health Technology Assessment (HTA). Företaget gör analys för deras kunder. Tyvärr är de arbetsmetoder inom företaget inte effektiv. Nya verktyg och metoder måste tillämpas inom företaget. Synergus AB har beslutat att tillämpa datahantering i deras dagliga arbete. Mitt uppdrag i detta projekt var att bygga dataset för analys och skapa arbetsflöde för framtida användning med en datahanteringsplatform. För mitt eget intresse, jag utförde en studie av datahantering för att förstå hur denna nya teknologi fungerar. Under projektet har jag arbetat med fyra data källor. De var Microsft Excel kalkylblad, CSV fil, MS Access databas och JSON fil. Jag byggde dataset företaget behöver. Jag också utförde ett fall studie om datahanteringsprocess. Jag fokuserade mig på de tre steg inom datahantering, nämligen inmatning, bearbetning och utmatning. Efter projektet kom jag till en slutsats att datahantering erjuder bättre prestanda och funktionelitet. Det är också lätt att lära sig och använda.

Abstract:

The rapid growth of medical sciences and technologies created the need to manage data generated by sophisticated medical equipment (e.g. lab results, vital signs, etc.). This class of equipment, especially in the modern Intensive Care Unit (ICU), emits large quantities of latient data which medical staff usually records on log sheets.
This thesis presents a database design that allows abstract definition of data types, and offers a unified view of data during the development phase, distinct levels of data management and a higher degree of system flexibility. This database model is an implementation of a database for a Patient Data Management System (PDMS) developed for use in the ICU of the Montreal Children's Hospital. The PDMS has a variety of application modules that handle and process various types of data according to functionality requirements.

Abstract:

Since the HITECH (Health Information Technology for Economic and Clinical Health) Act was enacted, healthcare providers are required to achieve “Meaningful Use.” CPOE (Clinical Provider Order Entry), is one such requirement. Many providers prefer to dictate their orders rather than typing them. Medical vocabulary is wrought with its own terminology and department-specific acronyms, and many ASR (Automated Speech Recognition) systems are not trained to interpret this language. The purpose of this thesis research was to investigate the use and effectiveness of ASR in the healthcare industry. Multiple hospitals and multiple clinicians agreed to be followed through their use of an ASR system to enter patient data into the record. As a result of this research, the effectiveness and use of the ASR was examined, and multiple issues with the use and accuracy of the system were uncovered.

Abstract:

Accurate predictions of patient volume are an essential tool to improve resource allocation and doctor utilization in the traditional, as well as the digital health care domain. Varying methods for patient volume prediction within the traditional health care domain has been studied in contemporary research, while the concept remains underexplored within the digital health care domain. In this paper, an evaluation of how two different non-linear state-of-the-art time series prediction models compare when predicting patient volume within the digital health care domain is presented. The models compared are the feed forward Multi-layer Percepron (MLP) and the recursive Long Short-Term Memory (LSTM) network. The results imply that the prediction problem itself is straightforward, while also indicating that there are significant differences in prediction accuracy between the evaluated models. The conclusions presented state that that the LSTM model offers substantial prediction advantages that outweigh the complexity overhead for the given problem.
En korrekt förutsägelse av patientvolym är essentiell för att förbättra resursallokering av läkare inom traditionell liksom digital vård. Olika metoder för förutsägelse av patientvolym har undersökts inom den traditionella vården medan liknande studier inom den digitala sektorn saknas. I denna uppsats undersöks två icke-linjära moderna metoder för tidsserieanalys av patientvolym inom den digitala sjukvården. Modellerna som undersöks är multi-lagersperceptronen (MLP) samt Long Short-Term Memory (LSTM) nätverket. Resultaten som presenteras indikerar att problemet i sig är okomplicerat samtidigt som det visar sig finnas signifikanta skillnader i korrektheten av förutsägelser mellan de olika modellerna. Slutsatserna som presenteras pekar på att LSTM-modellen erbjuder signifikanta fördelar som överväger komplexitets- och prestandakostnaden.

Abstract:

This thesis is about two different theoretical interpretations of objects and object-orientation in design of health care information systems – the interpretations of Activity Theory/Developmental Work Research and Computer Science respectively. One motive to my interest in objects of work and software, is to better understand the problems and possibilities in an inter¬dis¬ciplinary research project. With an origin in 2001, a Wound Care Project began as a joint R & D endeavour with the initial idea of utili¬zing digital photos. Soon, an information system (“Hedvig”) was developed for the purpose of managing digital photos and related treatment records on wounds. Later, this work expanded in creation of a distributed information system (“Helar”), a digital prototype for support of wound care treatment. Eventually, the thesis is summing up reflections related to the object concepts. AT/DWR has its strength in analysis and design of required change in a work practice but is still weak in method and techniques for support of making specific computa¬tional systems. In a way this shortcoming is thought of to be balanced by the technological CS discipline of which one of its main forces is to develop theory and practice for construction of computational information systems. This thesis suggest, in the inter¬dis¬ciplinary field of Health Care Information Systems Design, a further developed object con¬cept, and related scenarios and use cases, as a way of taking advantage of a combination of those two different strengths.
Avhandlingen handlar om två olika teoretiska tolkningar av objekt och objektorientering i design av informationssystem för hälso- och omvårdnadsarbete - tolkningar utifrån verksamhetsteori/utvecklande arbetsforskning (activity theory/developmental work research: AT/DWR) å ena sidan och datavetenskap (computer science: CS) å den andra. Ett motiv för mitt intresse för objekt i arbete och i programvara, är att bättre förstå problem och möjligheter i ett tvärvetenskapligt forskningsprojekt. Med en början i 2001, startade ett sårvårdsprojekt som ett forsknings- och utvecklingsarbete med den initiala idén att nyttja digitala foton, och snart utvecklades ett informationssystem ("Hedvig") för syftet att hantera digitala foton och annan relaterad behandlingsdokumentation för sårvård. Senare expanderade detta arbetet i skapandet av ett distribuerat informationssystem ("Helar"), en digital prototyp för stöd av sårbehandlingsarbete. Denna avhandling summerar reflektioner relaterade till objektbegreppen. AT/DWR har sin styrka i analys och design av efterfrågad förändring av en arbetspraktik, men är fortfarande svag i metod och tekniker för att stödja skapandet av specifika datorsystem. På ett sätt är det här tillkortakommandet tänkt att balanseras av den teknologiskt datavetenskapliga disciplinen, där en av dess främsta drivkrafter är att utveckla teori och praktik för konstruktion av datoriserade informationssystem. I det tvärvetenskapliga fältet av design av informationssystem för hälso- och omvårdnadsarbete, föreslår denna avhandling fortsatt utveckling av objektkoncepten, och utveckling av de relaterade "scenarios" och "use cases", som ett sätt att dra fördel av en kombination av dessa två olika förtjänster, som de olika disciplinerna står för. objekt, objektorientering, sårvård, digitala foton, verksamhetsteori, datavetenskap, informationssystem

Abstract:

Objectives: First, to identify the core Electronic Health Records (EHR) functionalities available to physicians who work in private and public health care facilities in Trinidad and Tobago and the extent to which physicians are using each function. Second, to understand the rate of adoption of Electronic Health Records in private and public hospitals/clinics, and finally, to identify the barriers to adoption of Electronic Health Records in private and public hospitals/clinics in Trinidad and Tobago. Background: The two largest public hospitals in Trinidad and Tobago, Port of Spain General Hospital and San Fernando General Hospital, utilized paper medical records. In Trinidad and Tobago, there is little known about the EHR functions available and being used, adoption rates, and barriers to adoption of EHR in the private and public sectors. Method: Electronic Health Records (n = 130) questionnaires were sent to number of health care practices in the private and public facilities in the five regions of Trinidad and Tobago, in order to understand availability and use of EHR, adoption rates, and barriers to the use of EHR. Results: The most commonly available function for the private and public physicians was Health Information and Data with respective scores of 58% and 29%. Sixty-three percent of the private physicians who adopted EHR reported using the Result Management and Order Management functions. The public physicians who had adopted EHR reported they were not utilizing the Decision Support, Result Management, and Order Management functions. There was no statistical difference between private and public physicians for the available and used functions. A total of 53 private and 19 public physicians responded to the survey (55% response rate). Thirteen (25%) private physicians reported adopting EHR and 2(11%) public physician reported adoption of EHR. Private and public physicians cited start-up cost and technical limitations of systems as the barriers to their practices' adoption of EHR. Conclusion: Findings showed the same availability and use of core functionalities, as well as adoption rate among the private and public facilities, and slightly fewer barriers in the private practices. A larger sample is merited to understand if there is any statistically significant difference between the two groups.

Abstract:

This thesis explores change and resistance to change of IT systems in organisations from a sociotechnical perspective. The work is drawing on empirical data gathered during two Action Research projects in Swedish Health Care: one regarding the deployment of electronic patient record systems within health care organisations, and the other regarding the deployment of eHealth services geared towards patients and citizens. Resistance to change is classified as an indicator of social inertia, and the concept of counter-implementation, comprising three general strategies to obstruct change initiatives, is used to highlight the political aspects of social inertia. For the analysis, the concept of social inertia is used as a point of departure towards inertia in sociotechnical systems by applying values and principles from sociotechnical systems research, most prominently the interdependence-characteristic. This extended concept is used to show and discuss how IT systems can either enforce change or be a source of inertia preventing change in organisations, and such planned or inadvertent effects of implementing IT systems are discussed as a significant source of user resistance.

Abstract:

Computerization has had a large impact on hospital intensive care units, allowing continuous monitoring and display of physiological patient data. Treatment of the critically ill patient, however, now requires assimilating large amounts of patient data.
Computers can help by processing the data and displaying the information in easy to understand formats. Also, knowledge-based systems can provide advice in diagnosis and treatment of patients. If these systems are to be effective, they must be integrated into the total hospital information system and the separate computer data must be jointly integrated into a new database which will become the primary medical record.
This thesis presents the design and implementation of a computerized database for an intensive care unit patient data management system being developed for the Montreal Children's Hospital. The database integrates data from the various PDMS components into one logical information store. The patient data currently managed includes physiological parameter data, patient administrative data and fluid balance data.
A simulator design is also described, which allows for thorough validation and verification of the Patient Data Management System. This simulator can easily be extended for use as a teaching and training tool for PDMS users.
The database and simulator were developed in C and implemented under the OS/2 operating system environment. The database is based on the OS/2 Extended Edition relational Database Manager.

Abstract:

IMIS (Integrated Mobile Information System for Diabetic Healthcare) aims at providing healthcare on both stationary and mobile platform, which is based on Engström’s triangle model in Activity Theory. It focuses on the need for communication and information accessibility between care-providers and their shared patients. Based on the identified need in the target area, IMIS has decided to construct a network-based communication system to support communication and accessibility to patients’ journal. Since the system integrates various roles from the heath care organization, it is a challenge to provide a useful software program to the group members. In order to facilitate the application and enhance the Human-Computer interaction of the system, agent technology is applied to increase the flexibility factor so that the system could be self-adapted to a wider range group of users.

Besides, this thesis also introduces the approach of using social-psychology — Activity theory in HCI, and discuss the integration of these different disciplines. The Multi-agents System is applied with Gaia methodology from micro perspectives. From the macro perspective Activity theory constructs the coordination mechanism of the different agents. A prototype is applied based on the different model of our research.

Abstract:

The healthcare service is under pressure to do more with less, and changing the way the service is modelled could be the key to saving resources and increasing efficacy. This change could be possible using patient-centric care models. This model would include straightforward and easy-to-use telemonitoring devices and a flexible data management structure. The structure would maintain its state by ingesting many sources of data, then tracking this data through cleaning and processing into models and estimates to obtaining values from data which could be used by the patient. The system can become less disease-focused and more health-focused by being preventative in nature and allowing patients to be more proactive and involved in their care by automating the data management. This work presents the development of a new device and a data management and analysis system to utilise the data from this device and support data processing along with two examples of its use. These are signal quality and blood pressure estimation. This system could aid in the creation of patient-centric telecare systems.

Abstract:

The objective of this project was to study the area of generic transfer of comprehensive medical data.The work presented in this thesis had as its main premise the belief that generic transfer of comprehensive medical data will help towards the goal of better healthcare particularly in an environment of shared care. It studied the main methods of data transfer available at present, and as a result carried out an in depth review of one such method adopted by the National Health Service (NHS). Criticism of this method was made. These criticisms lead on to the development of an alternative method of generic data transfer based on an emerging European standard for the storage of medical data. This in turn led on to the consideration of data in legacy systems. Finally, an evaluation of the developed method was undertaken.

Full text

Abstract:

Providing advanced health care at home rather than in a hospital creates a greater quality of life for patients and their families. It also lowers the risk of hospital-acquired infections and accelerates recovery. The overall cost of care per patient is decreased. Manual scheduling of patient visits by health care professionals (HCPs) has become a bottleneck for increased patient capacity at SABH, a ward providing advanced pediatric health care at home (“Sjukhusansluten Avancerad Barnsjukvård i Hemmet” in Swedish), since many parameters need to be taken into account during scheduling. This thesis aims to increase the efficiency of SABH’s daily scheduling of personnel and resources by designing an automated scheduler that constructs a daily schedule and incorporates changes in it when needed in order to remove scheduling as a limitation for increased patient capacity. Requirements on a feasible schedule are identified in cooperation with SABH and literature is investigated about similar areas where the scheduling process has been automated. The scheduling is formulated as a computerized problem and investigated from the perspective of theoretical computer science. We show that the scheduling problem is NP-hard and can therefore not be expected to be solved optimally. The algorithm for scheduling the visits minimizes violations of time windows and travel times, and maximizes person continuity and workload balancing. The algorithm constructs an initial solution that fulfills time constraints using a greedy approach and then uses local search, simulated annealing, and tabu search to iteratively improve the solution. We present an exact rescheduling algorithm that incorporates additional visits after the original schedule has been set. The scheduling algorithm was implemented and tested on real data from SABH. Although we found the algorithm to be efficient, automatic transfer of data from the patient journal system is an imperative for the scheduler to be adopted.
Barn som får avancerad sjukvård hemma istället för på sjukhus tillfrisknar ofta snabbare och risken för vårdrelaterade infektioner minskar. Barnen och deras familjer blir mer välmående av att få vistas i sin hemmiljö. På Astrid Lingrens barnsjukhus i Stockholm erbjuds avancerad hemsjukvård av avdelningen Sjukhusansluten Avancerad Barnsjukvård i Hemmet (SABH). För att schemalägga när patienterna ska besökas av sjukvårdspersonalen behöver många olika faktorer beaktas, detta sker idag helt manuellt. Den manuella schemaläggningen utgör en naturlig begränsning av SABHs patientkapacitet. Denna uppsats syftar till att effektivisera schemaläggningsprocessen hos SABH genom att föreslå en automatiserad lösning som hanterar koordinering av personal och resurser och dem förändringar som behöver göras i schemat under dagen, för att få bort schemaläggningsprocessen som ett hinder mot ökad patientkapacitet. Krav på schemaläggningen identifieras i diskussion med SABH och genom att studera litteratur kring liknande områden där schemaläggning lösts automatiserat. Vi formulerar schemaläggningen som ett datologiskt problem och analyserar det med utgångspunkt i teoretisk datalogi. Vi visar att problemet är NP-svårt och därför inte kan förväntas lösas optimalt inom rimlig tid. Vår lösning approximerar istället fram ett rimligt svar, där fokus hos algoritmen är att patienterna ska besökas de tider de behöver, personalens restider ska vara så korta som möjligt samtidigt som arbetsbördan hos personalen ska vara så lika fördelad som möjligt och patienterna ska, i den mån det är möjligt, få vård av samma personal. Med en girig algoritm konstrueras ett initialt schema som uppfyller de grundläggande kraven, detta schema förbättras med lokalsökning, simulated annealing och tabusökning. En exakt lösning framställs för uppdatering av schemat. Algoritmen för att lägga ett dagligt schema (utan uppdateringar) implementerades och testades med riktigt data från SABH. Vår algoritm visade sig vara effektiv, men för att kunna göra hela schemaläggningsprocessen effektiv behöver den integreras med journalsystemet.

Abstract:

In the field of medicine, decisions are often difficult to make in the absence of clear symptoms, decisive test results and adequate patient involvement. Medicine in most cases is still an art, using science for its basic foundation. Everyday practice relies on the case-study method, trial and error, and intuitive judgement. In some medical specialties there is heavy reliance on intangibles. For example, human motivation plays a significant role in complex medical decisions affected by many variables which remain unquantifiable and intangible; indeed most variables that determine outcome are hidden, including human motivation. The complexity of medical information systems demands that new ways be investigated that emphasize timeliness and efficiency. Medical information systems are no longer centralized; they are distributed over networks and the Internet. Interoperability has become a requirement in order for these heterogeneous systems be able to exchange information and work together in a cooperative manner. For this reason the design of decision processes within the general domains of medicine require further analyzation and establishing a methodology for developing a flexible agent architecture for the creation of intelligent agent systems in medicine. Thus, this research provided the underlying theoretical framework for the design of interactive intelligent agents in the medical domain examining the design of open and flexible architectures. In the last decade rapid development of agent technologies has occurred. Research of multi-agent systems sprung from earlier works in artificial intelligence and decision sciences. Complementing the study of agent technologies is the discipline of mathematical modeling. Adapted Markov models were applied to facilitate the methodology of the study emphasizing the process by which real decisions are formalized rather than the solution to already formalized problems. Another important element of this dissertation was the use of clinical pathways; fundamental guidelines that are components of managed health care. Clinical pathways were at the core of the architecture and formed the basis of a suitable expandable and adaptive Markov model. The results of the model are a derivation of intelligent agent architecture for the medical domain. The methodology exploited the generality, flexibility and normative power of Markov models, particularly, fully observable Markov decision processes (FOMDP) and partially observable Markov decision processes (POMDP). Based on both the FOMDP and POMDP, an expandable observable Markov decision process (EOMDP) model was formulated. The formulated model was further revised and reformulated based on the phenomenological observation and measure of clinical pathways. This approach is mathematically sound, computationally efficient, and intuitively appealing.

Abstract:

Hearing loss is considered a global health concern with 466 million people affected worldwide. Current hearing health care delivery models are based on several consecutive face-to-face consultations that occur in-person. Information and communications technology, and especially mobile technology, can be used to support or enhance health care delivery. This can be employed in addition, or as an alternative to, current patient treatment pathways. This project developed a hybrid hearing health care approach by combining online and face-to-face services. The services were offered using a five-step approach: (1) online hearing screening, (2) motivational engagement by voice/video calling, messaging, or emailing, (3) diagnostic hearing testing in a face-to-face appointment, (4) counseling, hearing aid trial and fitting using face-to-face and online methods, and (5) online aural rehabilitation, counseling and ongoing coaching using face-to-face and online methods. Three studies were conducted. Study I investigated the readiness, characteristics and behaviors of patients who sought hybrid hearing health care. Over three months (June–September 2017), 462 individuals completed the online hearing screening test: 59% (271/462) of those failed (age M = 60; SD = 12), indicating that further assessment and treatment might be required. These patients had been aware of their hearing loss for a period of between 5 to 16 years. A significant positive correlation was observed between age and speech reception threshold (r = 0.21; p < .001), where older participants presented with poorer scores. Five participants completed readiness measurement scales and attended a face-to-face diagnostic hearing evaluation during this time. Study II investigated patient uptake, experience and satisfaction with hybrid hearing health care using a process evaluation. The process evaluation study was conducted over a three-month period for patients who sought services from the clinic over a period of 19 months (June 2017–January 2019). A total of 46 patients seen at the clinic were invited to complete an online questionnaire regarding their experiences and satisfaction with the steps completed and services provided. Of those, 31 (67%) patients responded (age M = 66; SD = 16). Of the 61% of patients who had previously sought hearing services, 95% reported the hybrid clinic services as superior. Two main themes emerged from the patient’s comparison of their experience with the hybrid clinic versus previous experiences: clinician engagement (personal attention, patience, dedication, thorough explanations, professional behavior, exceeding expectations, friendliness and trust) and technology (latest technology, advanced equipment and hearing aid trial). Patients who completed all five steps, including acquiring hearing aids and taking part in an online aural rehabilitation program (continued with hearing health care), were significantly older and had significantly poorer speech reception thresholds compared to those who did not acquire hearing aids after the diagnostic hearing test and hearing aid trial (discontinued hearing health care). A significant positive correlation was found between age and the number of face-to-face appointments attended per patient (r = 0.37; p = .007). Study III investigated whether digital proficiency (proficiency with mobile devices and computers) was a predictor of the uptake of hybrid hearing health care. A total of 931 individuals failed the online hearing screening test and had submitted their details to the clinic for further care over a 24-month period (June 2017–June 2019). Of the 931 online test takers, 53 persons (age M = 64; SD = 15) who attended a face-to-face diagnostic hearing testing completed a mobile device and computer proficiency questionnaire. An exact regression model identified age as the factor associated with patients completing all five steps, including acquiring hearing aids and taking part in an online aural rehabilitation program (continued with hearing health care) from a hybrid model (β = .07; p = .018). Older patients were more likely to continue to seek hearing health care. Digital proficiency was not significantly associated with adults with hearing loss taking up services through a hybrid hearing health care model. The results from these three studies demonstrate that asynchronous internet-based services such as an online hearing screening test can be used to create awareness of hearing health care. It is possible to provide online support to patients during the initial stages of seeking hearing health care online prior to the first face-to-face visit. Patient uptake, satisfaction and experience of using hybrid hearing health care services are positive when compared to traditional methods of service delivery. Hearing health care models that combine face-to-face and online methods hold promise for audiologists willing to incorporate online modalities into current treatment pathways. This research project highlights the opportunity for audiologists to provide services and personalized support to patients using a combination of face-to-face and online modalities.

Full text

Abstract:

In this thesis, new computer vision based techniques are proposed to detect falls of an elderly person living alone. This is an important problem in assisted living. Different types of information extracted from video recordings are exploited for fall detection using both analytical and machine learning techniques. Initially, a particle filter is used to extract a 2D cue, head velocity, to determine a likely fall event. The human body region is then extracted with a modern background subtraction algorithm. Ellipse fitting is used to represent this shape and its orientation angle is employed for fall detection. An analytical method is used by setting proper thresholds against which the head velocity and orientation angle are compared for fall discrimination. Movement amplitude is then integrated into the fall detector to reduce false alarms. Since 2D features can generate false alarms and are not invariant to different directions, more robust 3D features are next extracted from a 3D person representation formed from video measurements from multiple calibrated cameras. Instead of using thresholds, different data fitting methods are applied to construct models corresponding to fall activities. These are then used to distinguish falls and non-falls. In the final works, two practical fall detection schemes which use only one un-calibrated camera are tested in a real home environment. These approaches are based on 2D features which describe human body posture. These extracted features are then applied to construct either a supervised method for posture classification or an unsupervised method for abnormal posture detection. Certain rules which are set according to the characteristics of fall activities are lastly used to build robust fall detection methods. Extensive evaluation studies are included to confirm the efficiency of the schemes.

Through a mixed method approach, results show that the overall information quality provided in Chinese group is relatively poorer than those of English. About 40% of questioners form both groups are not capable of judging the best answer among choices. In terms of structural patterns, questioners from both language groups are less capable of asking questions with clear focuses. 4 structural patterns, including Chinese and English answers with good and poor quality, are identified. Furthermore, cultural differences are found to have a significant impact on the level of information quality in social Q&A site. Finally, recommendations to corresponding social sectors are made for improving the current information quality of social Q&A sites in future.

Abstract:

If you ask different kinds of care givers if they work in the same way or if they have the same needs of information when they meet a patient they would say no. In my usability study at Tierp’s health centre I have made contextual interviews with different types of care givers to identify their needs and requirements on the medical record systems. The aim is to make a conceptual design solution for a health issue-orientated medical record system. The different types of care giver think they have different needs. But after analyzing their needs I found out that before they meet a patient they all look into the medical records for patient information. They all want information about earlier diseases, referrals, test results and drugs. Their work is not so different from each others. How they work depends on what kind of health issue the patient has and their individual experience and practice. Some wants to look at many old medical records and other just want to look at their own. I have made a concept that allows the user to make personal settings for some parts in the design. My concept is two different kinds of overviews; one that is a patient overview thats how all present and earlier health issues, drugs and planned contact with the care.The other overview is called health issue overview and shows information about the health issue that the care giver is going to treat.

Abstract:

Health care education is developing and simulations, in different guises, are gaining increasing attention as a means of overcoming tensions between instructional models and educational objectives. The role of simulations is, however, yet to be fully defined and will be dependent on the actual impact simulations on educational practice. Research need to better understand this impact and contribute to developing simulation practices. There is, therefore, a strong need for research that can balance scientific stringency and practical utility. This presents a challenge in a field that is biased in favor of laboratory experiments where theoretical accounts are also rare. This thesis explores a new theoretical and methodological approach, as a means of meeting this challenge. It draws upon Rose Luckin's Ecology of Resources framework for redesigning learning contexts (2010) and it attempts to explore relations between learning context, learner interactions, and learning outcomes, in order to identify opportunities for the development of educational simulation practice. In researching different types of health care simulations in their own right, arguments have been made that it is necessary to strive for smaller and more useful generalizations. In response to this challenge, this thesis delineates one type of simulation context: collaborative educational computer-assisted simulation (ECAS) in health care education. After reviewing previous research on related topics, a model of this type of context has been developed. Based on this general model, the particular subfield of collaborative radiology in ECAS has been analyzed and researched. Four articles on this topic present empirical contributions that address different relations between context, learner interactions, and learning outcomes in collaborative radiology in ECAS. The first one explores how moving from a static tool to an ECAS changes what learners talk about, how they talk about it, and how they develop during training. The second one explores in more detail relations between the features of ECAS, the content of learner interactions, and the impact on learning. The third one explores how context design impacts peer interaction, and the fourth compares more and less successful groups in order to identify needs and opportunities for development of the learning context. The empirical data are used to discuss relations between learning context, learner interactions, and learning outcomes, and how collaborative scripts may be potentially useful in the development of collaborative ECAS in health care education. Such scripts could support for instance explicit dialogue about relations between context-dependent doing and subject-specific principles, thorough engagement with simulation feedback and inclusion of all simulations participants. A new path for health care simulation research is suggested, including a move beyond laboratory experiments towards dealing with the messiness of actual educational practice, a move beyond universal generalizations towards smaller-scale context considerate and more practically useful generalizations.

Abstract:

Organisations are increasingly deploying and using computer technology in various ways, involving the allocation of large amounts of capital and human resources. However, in many cases, computer deployment has been accompanied by failure, particularly in health care services. Therefore, information technology has raised grave questions, misunderstanding, fears, and hostility. This study emphasises the importance of computer deployment and development in developed and developing countries' health care services with examples from advanced and less advanced nations. It describes strategy development for IT/ISs using information system methodologies and explores the development of ISs strategy in the NHS in the light of fundholding and the internal market. A number of problems that commonly influence the success or failure of computer deployment and development are identified. These issues are explained through two case studies: the Omani health system and General Practices (GPRs) in the UK, which have introduced computers. The research focuses on five main sets of issues related to computer deployment and utilisation in health care: strategic planning; computer utilisation; computer fears; computer impact; and computer technical problems and performance. Users' overall satisfaction with systems in use is also considered. Data collection was carried out using two surveys. One survey was conducted in GPRs in Humberside and the other conducted in Royal Hospital and Sultan Qaboos University Hospital in Oman. Data sources included observations, review of relevant documents, such as reports, research papers and manuals, structured and non-structured interviews with selected users and a questionnaire. A number of conclusions can been drawn from this study: firstly, computer deployment, utilisation and development still faces problems in both the systems studied, more especially the Omani system. Secondly, GPRs have carried out strategic planning for computer deployment and utilisation and are prepared to use information system methodology for IT/IS strategy and there is a plan to use this for competitive advantage but Omani hospitals did not set a constructive strategic plan for their systems. Thirdly, the main problems of computer failure are related to human issues rather technical issues. The most important of these human issues are the style of the leadership planning, poor utilisation of computer applications, lack of skills and poor training. Finally, the results of the survey suggested that though the respondents were aware of the potential of computer technology, the problems of computer fears, training and lack of skills were experienced, and often, few individuals possessed computing knowledge. The author suggests several points to be considered: 1) that any thinking about computer deployment and development should employ appropriate information system development methodologies; 2) the decisions on computer deployment, use and development should be made by a special committee that has expertise in IT matters; 3) good strategic planning for computer deployment, use and development; should be connected to the organisation's overall strategy and 4) there is a need of mandate review for such development and planning. With these points in mind the researcher presents a diagram to help improving strategic planning and development of IT/IS methods with particular emphasis on the Omani environment.

Abstract:

Medical area has been benefited by the use of ICT (Information and Communication Technology) in recent days. CMIS (Combined Mobile Information System), our proposed model system, is such a system targeted for health care system. IMIS (Integrated Mobile Information System), a system for diabetic healthcare, which is being developed in Blekinge Institute of Technology will be taken as a case study for our proposed system. CMIS is a multi-role system with core service being medical-care related and others like self-monitoring, journal-writing, communicating with fellow patients, relatives, etc. The main reason for not using CMIS could be the security and privacy of the users' information. Any system connected to Internet is always prone to attack, and we think CMIS is no exception. The security and privacy is even more important considering the legal and ethical issues of the sensitive medical data. The CMIS system can be accessed through PDA (Personal Digital Assistant), smart phones or computer via Internet using GPRS (General Packet Radio Service)/UMTS (Universal Mobile Telecommunication System) and wired-communication respectively. On the other hand, it also increases the burden for security and privacy, related to the use of such communications. This thesis discusses various security and privacy issues arising from the use of mobile communication and wired communication in context of CMIS i.e., issues related to GPRS (mobile) and web application (using wired communication). Along with the threats and vulnerabilities, possible countermeasures are also discussed. This thesis also discusses the prospect of using MP2P (Mobile Peer-to-Peer) as a service for some services (for example, instant messaging system between patients) in CMIS. However, our main concern is to study MP2P feasibility with prospect to privacy. In this thesis, we have tried to identify various security and privacy threats and vulnerabilities CMIS could face, security services required to be achieved and countermeasure against those threats and vulnerabilities. In order to accomplish the goal, a literature survey was carried out to find potential vulnerabilities and threats and their solution for our proposed system. We found out that XSS (cross-site scripting), SQL injection and DoS attack being common for a web application. We also found that attack against mobile communication is relatively complex thus difficult to materialize. In short, we think that an overall planned security approach (routinely testing system for vulnerabilities, applying patches, etc) should be used to keep threats and attacks at bay.
