Point-of-care Ultrasound Diagnosis of Emphysematous Cholecystitis

A 49-year-old male presented to the emergency department with abdominal pain and generalized weakness. The physical examination was positive for right upper quadrant tenderness and positive Murphy’s sign. Point-of-care biliary ultrasound revealed signs of emphysematous cholecystitis. Emphysematous cholecystitis is a rare biliary pathology with a high mortality rate. It differs from acute cholecystitis is many ways. It has unique ultrasound characteristics. This case highlights the use of point-of-care ultrasound to diagnose a rare biliary condition

Point-of-Care Ultrasound in the Emergency Department

Point-of-care ultrasound (POCUS) is a useful diagnostic tool and has become an integral part of the care provided in the Emergency Department. It has evolved over the past two decades to include diagnostic and therapeutic skills. POCUS helps emergency physicians improve their diagnostic accuracy and provide better overall patient care. This chapter will summarize 13 core POCUS applications that are considered within the diagnostic armamentarium of all emergency physicians

Impact of Ramadan on Emergency Department Patients Flow; a Cross-Sectional Study in UAE

Introduction: Ramadan, the ninth month of the Islamic lunar calendar, is, to Muslims, the holiest month of the year. During this month, young, able-bodied Muslims are commanded to abstain from food and drink from dawn to dusk. Objective: The objective of the study is to analyze emergency department (ED) patients flow during the holy month of Ramadan and compare it to non-Ramadan days. We hypothesized that Ramadan would affect ED attendance by altering peak hours, and expected a dip in attendance around evening time (after sunset). Methods: In Abu Dhabi, United Arab Emirates, a retrospective study was conducted at a tertiary hospital (2014-2016). The data was strategically separated and patient presence was analyzed year-wise, weekday basis and based on the hourly presence of the patients in the ED of the chosen hospital. Results: A total of 45,116 ED’s patient visits were analyzed over the mentioned study period. There was a difference in the total volume of Ramadan and non-Ramadan patient between the years 2014-2016. In all of the years, the highest percentage of visits was during the non-Ramadan days and this had a small fluctuation from 53% in 2014 to 52% in 2016 (p=0.001). It was observed from the collected data that 53% of the patients were present in the hospital during the fasting hours whereas 47% were present during the non-fasting hours (p<0.001). Conclusion: We were successfully able to derive a pattern from the data of 3 years in relation to the patient flow in the ED of the hospital. Moreover, we observed the difference in the patient arrival pattern between the Ramadan and non-Ramadan days in the hospital along with the predominant categorization of patient chief complaints.  Our study identified a unique pattern of ED hourly visits during Ramadan

Professionalism-training in undergraduate medical education in a multi-cultural, multi-ethnic setting in the Gulf Region: an exploration of reflective essays

Abstract Background Despite the established need to prioritize professionalism-training in developing future physicians, very few medical programs in the Gulf Region embed in their curricula discrete contextualized courses aimed at developing the corresponding competencies, while fostering self-directed learning. This study aims at exploring the perception of undergraduate medical students in a multi-cultural, multi-ethnic setting regarding their understanding of, and personal experience with professionalism through their engagement with the content of an innovative curriculum-based professionalism course, offered at a Medical School in Dubai, United Arab Emirates. Methods The study used a qualitative phenomenological research design. Out of 33 students, 29 students had submitted reflective essays. The content of these essays was inductively analyzed following a six-step framework for conducting thematic analysis. The framework’s steps include familiarizing oneself with the data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the report. Findings The inductive qualitative analysis generated the Professionalism Learning Journey model. This conceptual model includes four interconnected themes: Awareness, Acknowledgement, Realization, and Application. The generated model depicts the trajectory that the learners appear to experience while they are engaging with the content of the course. Conclusion Integrating a professionalism-training course into an undergraduate medical curriculum is likely to be positively appraised by the learners. It raises their awareness, enables them to value the subject matter and the sophistication of its application, and empowers them to put into practice the taught principles, on an individual basis and collectively. This is especially true when the course is entrenched in constructivism experiential learning theory and designed to foster self-directed learning. The introduced conceptual model, in conjunction with the innovative professionalism-training course curriculum, can serve as a template for other competencies and other schools

Bedside Ultrasound Reduces Diagnostic Uncertainty and Guides Resuscitation in Patients With Undifferentiated Hypotension.

Objectives: Utilization of ultrasound in the evaluation of patients with undifferentiated hypotension has been proposed in several protocols. We sought to assess the impact of an ultrasound hypotension protocol on physicians\u27 diagnostic certainty, diagnostic ability, and treatment and resource utilization. Design: Prospective observational study. Setting: Emergency department in a single, academic tertiary care hospital. Subjects: A convenience sample of patients with a systolic blood pressure less than 90 mm Hg after an initial fluid resuscitation, who lacked an obvious source of hypotension. Interventions: An ultrasound-trained physician performed an ultrasound on each patient using a standardized hypotension protocol. Differential diagnosis and management plan was solicited from the treating physician immediately before and after the ultrasound. Blinded chart review was conducted for management and diagnosis during the emergency department and inpatient hospital stay. Measurements and Main Results: The primary endpoints were the identification of an accurate cause for hypotension and change in physicians\u27 diagnostic uncertainty. The secondary endpoints were changes in treatment plan, use of resources, and changes in disposition after performing the ultrasound. One hundred eighteen patients with a mean age of 62 years were enrolled. There was a significant 27.7% decrease in the mean aggregate complexity of diagnostic uncertainty before and after the ultrasound hypotension protocol (1.85-1.34; -0.51 [95% CI, -0.41 to -0.62]) as well as a significant increase in the absolute proportion of patients with a definitive diagnosis from 0.8% to 12.7%. Overall, the leading diagnosis after the ultrasound hypotension protocol demonstrated excellent concordance with the blinded consensus final diagnosis (Cohen k = 0.80). Twenty-nine patients (24.6%) had a significant change in the use of IV fluids, vasoactive agents, or blood products. There were also significant changes in major diagnostic imaging (30.5%), consultation (13.6%), and emergency department disposition (11.9%). Conclusions: Clinical management involving the early use of ultrasound in patients with hypotension accurately guides diagnosis, significantly reduces physicians\u27 diagnostic uncertainty, and substantially changes management and resource utilization in the emergency department
