ABSTRACT
INTRODUCTION: Simulation training that includes deliberate practice is effective for procedural skill training. Delivering feedback remotely and asynchronously has been examined for more cost-efficient training. This prospective randomized study aimed to compare 2 feedback techniques for simulation training: synchronous direct feedback versus asynchronous distance feedback (ASYNC). METHODS: Forty anesthesia and internal medicine residents were recruited after study approval by the institutional ethics committee. Residents reviewed instructional material on an online platform and performed a pretraining assessment (PRE) for peripherally inserted central catheter (PICC) placement. Each resident was then randomly assigned to 1 of 2 training types, practice with synchronous direct feedback (SYNC) or practice with ASYNC. Training consisted of four, 1-hour practice sessions; each was conducted once per week. Both groups underwent posttraining evaluation (POST). The PRE and POST assessments were videotaped and evaluated by 2 independent, blinded reviewers using a global rating scale. RESULTS: Thirty-five residents completed the training program and both evaluations. Both groups had significantly improved global rating scale scores after 4 sessions. The SYNC group improved from 28 to 45 points (P < 0.01); the ASYNC group improved from 26.5 to 46 points (P < 0.01). We found no significant between-group differences for the PRE (P = 0.42) or POST assessments (P = 0.13). CONCLUSION: This simulation-based training program significantly improved residents' peripherally inserted central venous catheter placement skills using either modality. With these results, we are unable to demonstrate the superiority of synchronous feedback over ASYNC. Asynchronous feedback training modality represents a new, innovative approach for health care procedural skills training.
ABSTRACT
Purpose: To date, there are no training programs for basic suturing that allow remote deliberate practice. This study seeks to evaluate the effectiveness of a basic suture skills training program and its 6-month skill retention applying unsupervised practice and remote digital feedback. Methods: Fourth-year medical-student trainees reviewed instructional videos from a digital platform and performed unsupervised practice as needed at their homes. When they felt competent, trainees uploaded a video of themselves practicing the skill. In < 72 h, they received expert asynchronous digital feedback. The course had two theoretical stages and five video-based assessments, where trainees performed different suturing exercises. For the assessment, a global (GRS) and specific rating scale (SRS) were used, with a passing score of 20 points (max:25) and 15 (max:20), respectively. Results were compared to previously published work with in-person expert feedback (EF) and video-guided learning without feedback (VGL). A subgroup of trainees underwent a 6-month skills retention assessment. Results: Two-hundred and forty-three trainees underwent the course between March and December 2021. A median GRS of 24 points was achieved in the final assessment, showing significantly higher scores (p < 0.001) than EF and VGL (20.5 and 15.5, respectively). Thirty-seven trainees underwent a 6-month skills retention assessment, improving in GRS (23.38 vs 24.03, p value = 0.06) and SRS (18.59 vs 19, p value = 0.07). Conclusion: It is feasible to teach basic suture skills to undergraduate medical students using an unsupervised training course with remote and asynchronous feedback through a digital platform. This methodology allows continuous training with the repetition of quality practice, personalized feedback, and skills retention at 6 months.
