Does an instructional video as a stand-alone tool promote the acquisition of practical clinical skills? A randomised simulation research trial of skills acquisition and short-term retention.
Trial report in BMC medical education, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundThe effectiveness of instructional videos as a stand-alone tool for the acquisition of practical skills is yet unknown because instructional videos are usually didactically embedded. Therefore, we evaluated the acquisition of the skill of a humeral intraosseous access via video in comparison to that of a self-study with an additional retention test.
methodsAfter ethical approval, we conducted two consecutive studies. Both were designed as randomised controlled two-armed trials with last-year medical students as independent samples at our institutional simulation centre of a tertiary university hospital centre. In Study 1, we randomly assigned 78 participants to two groups: Vid-Self participants watched an instructional video as an intervention, followed by a test, and after seven days did a self-study as a control, followed by a test. Self-Vid ran through the trial in reverse order. In Study 2, we investigated the influence of the sequence of the two teaching methods on learning success in a new sample of 60 participants: Vid-Self watched an instructional video and directly afterward did the self-study followed by a test, whereas Self-Vid ran through that trial in reverse order. In Studies 1 and 2, the primary outcome was the score (worst score = 0, best score = 20) of the test after intervention and control. The secondary outcome in Study 1 was the change in score after seven days.
resultsStudy 1: The Vid-Self (Participants n = 42) was superior to the Self-Vid (n = 36) (mean score 14.8 vs. 7.7, p < 0.001). After seven days, Self-vid outperformed Vid-Self (mean score 15.9 vs. 12.5, p < 0.001). Study 2: The Vid-Self (n = 30) and Self-Vid (n = 30) scores did not significantly differ (mean 16.5 vs. mean 16.5, p = 0.97).
conclusionAn instructional video as a stand-alone tool effectively promotes the acquisition of practical skills. The best results are yielded by a combination of an instructional video and self-study right after each other, irrespective of sequence. TRIAL REGISTRATIONS: ClinicalTrials.gov: NCT05066204 (13/04/2021) (Study 1) and NCT04842357 (04/10/2021) (Study 2).
