Meta Analysis Comparative Study
Comparison of peer-assisted learning with expert-led learning in medical school ultrasound education: a systematic review and meta-analysis.
Teaching point-of-care ultrasonography (PoCUS) to medical students is resource intensive. Peer-assisted learning, where the teacher can be a medical student, may be a feasible alternative to expert-led learning. The objective of this systematic review and meta-analysis was to compare the PoCUS performance assessments of medical students receiving peer-assisted vs expert-led learning. ⋯ This meta-analysis found that peer-assisted learning was a reasonable alternative to expert-led learning for teaching PoCUS skills to medical students.

Acetaminophen overdose is a leading cause of acute liver failure in developing countries. N-acetylcysteine (NAC) is a highly effective antidote for acetaminophen hepatotoxicity, typically initiated in the emergency department. Due to a known high rate of errors with the standard three-bag IV NAC protocol, in 2019, the Ontario Poison Center changed to a modified 3% IV NAC one-bag protocol. This study was undertaken to determine the frequency and types of errors associated with the use of this protocol. ⋯ The rate of errors identified with this 3% IV NAC one-bag protocol is lower than reported for the standard three-bag protocol, but remains high due to dosing errors. Previously reported issues with prolonged interruptions in therapy with the standard three-bag protocol were low with the current 3% one-bag protocol. Although severe outcomes are rare, IV NAC overdose can be fatal. Identifying local factors in emergency departments that can contribute to administration errors (i.e., dose calculation, pump programming issues) can enhance the safety of this important antidote.

Approximately five years ago, the Royal College emergency medicine programs in Canada implemented a competency-based paradigm and introduced the use of Entrustable Professional Activities (EPAs) for assessment of units of professional activity to assess trainees. Many competency-based medical education (CBME) based curricula, involve assessing for entrustment through observations of EPAs. While EPAs are frequently assessed in clinical settings, simulation is also used. This study aimed to characterize the use of simulation for EPA assessment. ⋯ Our findings offer insight for other programs and specialties on how simulation for EPA assessment can best be utilized. Programs should use these findings when considering using simulation for EPA assessment.

Emergency Department (ED) renal point-of-care ultrasound (PoCUS) in renal colic by accredited specialists has good prognostic value. This may not be generalizable to under-resourced EDs. We investigated PoCUS in renal colic in our ED with lesser training. ⋯ Renal PoCUS could be performed by non-ED specialist/resident doctors to identify patients without hydronephrosis who rarely required urological intervention. Hydronephrotic patients could benefit from further risk stratification.
