Accuracy of focused cardiac ultrasound interpretation among emergency and critical care medicine residents in Ethiopia: A multi-center cross-sectional study
Introduction
Focused cardiac ultrasound (FoCUS) has emerged as a valuable tool in emergency and critical care medicine, allowing for rapid assessment of cardiac function and structure at the bedside. This rapid diagnostic technique holds particular promise in resource-limited settings like Ethiopia, where access to standard echocardiography may be limited and delayed. However, the accuracy of FoCUS interpretation is highly dependent on the operator's skills and expertise. To inform the design of effective interventions, the study aimed to assess the accuracy of FoCUS interpretation and associated factors among senior Emergency Medicine residents at two large referral teaching hospitals in Ethiopia.
Methods
A cross-sectional study was conducted from October to December 2023 among 80 residents at Tikur Anbessa Specialized Hospital and St. Paul's Hospital Millennium Medical College. To assess diagnostic accuracy, 15 pre-selected cardiac ultrasound videos (normal and pathological cases) were selected from American College of Emergency Physicians website and the PoCUS Atlas, and accurate interpretation was defined as correctly answering at least 12 out of 15 readings. A binary logistic regression model was fitted to identify significant factors at the 5% level of significance, where significant results were interpreted using adjusted odds ratio (AOR) with 95% confidence interval (CI).
Result
The overall accuracy in interpreting FoCUS findings was 47.5% (95% CI: 38.8–60.0%), with highest for collapsing Inferior Vena Cava (91.3%) and standstill (90.0%), and lowest for Regional Wall Motion Abnormality of Left Ventricle (46.3%). Residents who received training (AOR=4.14, 95%CI:1.32–13.04, p = 0.015), perceived themselves as skilled (AOR=4.81, 95%CI=1.06–21.82, p = 0.042), and felt confident in acquiring and interpretation (AOR=3.16, 95%CI=1.01–9.82, p = 0.047) demonstrated significantly higher accuracy.
Conclusion
The study identified a low overall accuracy in FoCUS interpretation, with accuracy improving with training and better perceived skill and confidence. Training programs with simulation, continuous education, and mentorship are crucial to enhance these critical skills.
