Academic literature on the topic 'Ultrasound skill performance'

The thyroid exam is an important clinical skill that is widely practiced by both primary care and specialty physicians. Despite this, there are few teaching models that allow for practice and assessment of proper examination technique. We developed a sensorized thyroid exam model and accompanying survey to capture clinical decision making and hands-on performance. Two endocrinologists performed the thyroid exam on the models. There was verbal consensus on clinical findings; however estimates on thyroid properties and size differed. Additional experiments with an ultrasound provided feedback on use of the model for hands-on and ultrasound-based examinations.

Although the screening of abdominal aortic diameter helps to identify men with abdominal aortic aneurysm and saves lives, there is need to coordinate and synchronize screening personnel's way to work. This article describes the design of a game based skill training application that could give the screening personnel an additional opportunity to refine measuring of abdominal aortic diameter in ultrasound images. The design work follows the steps of the Goal Directed design process. Consequently, the design activities are divided into six phases: the Research, Modelling, Requirements Definition, Framework Definition, Refinement and Development support. The design process described in this paper finishes with usability testing of an interactive prototype. The evaluation of the design was conducted with end users by studying their subjective ratings and performance on given tasks. The overall results of the usability testing show that the interactive prototype of the skill training application is not yet fully usable. Consequently, further improvement of the interface design is needed. The identified usability issues and collected qualitative and quantitative material about the interaction between test participants and the interface can guide the next design iteration and lead to more usable design.

Accurate resuscitation of the critically-ill patient using intravenous fluids and blood products is a challenging, time sensitive task. Ultrasound of the inferior vena cava (IVC) is a non-invasive technique currently used to guide fluid administration, though multiple factors such as variable image quality, time, and operator skill challenge mainstream acceptance. This study represents a first attempt to develop and validate an algorithm capable of automatically tracking and measuring the IVC compared to human operators across a diverse range of image quality. Minimal tracking failures and high levels of agreement between manual and algorithm measurements were demonstrated on good quality videos. Addressing problems such as gaps in the vessel wall and intra-lumen speckle should result in improved performance in average and poor quality videos. Semi-automated measurement of the IVC for the purposes of non-invasive estimation of circulating blood volume poses challenges however is feasible.

This task assesses the following clinical skills: … ● Patient safety ● Communication with patients and their relatives ● Information gathering ● Applied clinical knowledge … Mrs Zari Sardogan has a history of six weeks amenorrhoea, a positive pregnancy test and has presented with spotting PV. You are the registrar in the Early Pregnancy Assessment Unit. Your task is: … ● Take a focused history ● Interpret the data and ● Discuss management option … You have 10 minutes for this task (+ 2mins initial reading time). Please read the instruction to candidate. This clinical assessment task is to assess the skills of the candidate to take a focused history and organize appropriate investigations, reach a diagnosis and discuss the management options. They are expected only to organize transvaginal ultrasound, Beta HCG and progesterone at the outset. Show them the results of the investigations as they request them. Results Sheet A— ask them to interpret and arrange the next test Results Sheet B— Beta HCG Results Sheet C— Progesterone As the patient is asymptomatic, after due counselling, they should organize a repeat beta HCG in 48 hrs. Results Sheet D— Beta HCG (48 hrs after) As the beta HCG rise is suboptimal but more than 33%, the candidate may spontaneously or based on Zari’s wishes organize a repeat beta HCG and a repeat ultrasound. Results Sheet E— Beta HCG (48 hrs after Results Sheet D) Results Sheet F— Ask them to interpret and discuss the management options Record your overall clinical impression of the candidate for each domains (i.e. should this performance be pass, borderline, or a fail).

The performance and interpretation of ultrasound examination are very user-dependent that require significant training and experience. This chapter details the processes that should be adopted within an intensive care unit using point-of-care ultrasound to ensure that practitioners are appropriately trained and are able to maintain and develop their skills. The chapter also outlines recommendations regarding good practice in reporting and image storage, together with guidance regarding equipment management, to ensure patient safety.

This task assesses the following clinical skills: … ● Patient safety ● Communication with patients and their relatives ● Information gathering ● Applied clinical knowledge … You are an ST4 doctor covering Early Pregnancy Assessment Unit (EPAU). You have been asked to see 24- year- old Jaz Pringle in her third pregnancy. Her LMP was six weeks ago and has presented with left iliac fossa pain and light vaginal bleeding. Your task is: … ● To take a focussed history ● Organize the necessary investigations ● Discuss the results and diagnosis with Jaz ● Agree a management plan … You have 10 minutes for this task (+ 2mins initial reading time). This is a communication skills clinical assessment task that tests the candidate’s skills to take a focussed history, interpret and explain results and agree to a management plan having discussed the options. If they ask for the urine pregnancy test, tell them it is positive. If they arrange an ultrasound, provide them with the following result. ‘An empty uterus and a 2.3cm left sided adnexal mass with well- defined gestational sac medial to the left ovary with minimal fluid in pouch of Douglas. Right ovary appeared normal. Findings are highly suggestive of left sided tubal pregnancy’. If they organize beta HCG, tell them the nurse had sent it and the result is back and it is 2900IU/ml. Record your overall clinical impression of the candidate for each domain (e.g. should this performance be pass, borderline, or a fail). You are Ms. Jaz Pringle, a 24- year- old housewife who lives with her partner of four years. You have one child delivered by caesarean section for breech (bottom first) presentation three years ago. You had developed infection post caesarean section and were very unwell. You had needed admission to the hospital for 10 days and needed IV antibiotics. This was followed by an ectopic pregnancy 18 months ago whereby you ended up having key hole surgery and removal of your right fallopian tube with ectopic pregnancy. While you have not been actively trying for another pregnancy, you and your partner are happy with the thought of another pregnancy. However, you attended hospital due to some discomfort on the left side of the tummy and some vaginal bleeding on and off for two days. You are otherwise fit and well with no allergies. The candidate should arrange a urine pregnancy test, which will be positive. They should then organize a scan in the EPAU. The scan will suggest an ectopic pregnancy in your right tube. You are now extremely upset and anxious after the scan at the thought of possibly losing the only remaining tube and being rendered infertile. You want to know all possible options and would like to save the only fallopian tube if possible.

In Obstetrics, Ultrasound is used to access fetus growth which can be measured by Head Circumference. Accurate segmentation of fetal head is important for calculating Head Circumference. As Deep Learning is gaining popularity because of its state of the art performance, the various Deep Learning techniques for the segmentation of fetal skull are discussed in this article.

Helping resident surgeons quickly and accurately develop expertise in clinical skills is crucial for improving patient safety and care. Because most surgical skills require visually aided device manipulations, developing effective eye-hand coordination is a crucial component of most surgical training. While eye-hand coordination has typically been evaluated on the basis of time to complete a task and number of errors, growing evidence suggests that task performance can be distinguished by detecting eye gaze patterns and movement planning. However, few studies have explored methods for collecti

Abstract Human’s motion and its mechanisms had become interesting in the last years, where the medecine’s field search for rehabilitation methods for handicapped persons. Other fields, like sport sciences, professional or military world, search to distinguish profiles and ways to train them with specific purposes. Besides, recent findings in neuroscience try to describe these mechanisms from an organic point of view. Until now, different researchs had given a model about control motor that describes how the union between the senses’s information allows adaptable movements. One of this sense is
