Evidence¶

Wang L‐W 2025¶

Wang L‐W, Liu C‐H, Li W‐Y, Chiang W‐C, Chiu Y‐L, Ma M H‐M, Chen H‐L, Yang C‐W. (2025). Is ultrasound training sustainable? A systematic review of competency retention in healthcare trainees. Medical Education. https://doi.org/10.1111/medu.15751

q2 · i? · quant-synthesis · r2

Stratified analysis of 43 courses across the included studies, categorized using a 4-h threshold. The review reports "significantly greater competency decline with short courses" than long courses, with short courses also assessed at shorter median follow-up (2 vs 6 months).

"Participants demonstrated significantly greater competency decline with short courses, showing a median percentage change of −11.8% (IQR: −16.9% to −4.4%), compared with long courses at −2.6% (IQR: −6.8% to 1.3%)"
