Simulation-based mastery learning for intrathecal baclofen pump management in physical medicine and rehabilitation: A pilot study.

Abstract

Background: Simulation-based mastery learning (SBML) has demonstrated superiority as a procedural learning method. Implementation of SBML in Physical Medicine and Rehabilitation (PM&R) education has not been described and there is a paucity of literature regarding standardized procedural learning in this specialty.

Objective: To evaluate if implementation of intrathecal baclofen pump management SBML affects knowledge, attitudes, and skills in PM&R residents.

Design: Pretest-posttest design.

Setting: Academic rehabilitation hospital.

Participants: Twenty-two PM&R residents.

Interventions: Participants engaged in SBML steps: pre-test, demonstration of proper technique, deliberate practice, and a post-test.

Main outcome measures: Ability to achieve minimum passing score, quiz scores, and survey scores. Pre- and post-test results were compared using Wilcoxon signed-rank tests. Post graduate year (PGY)-3 and PGY-4 resident results were compared using Mann-Whitney U tests.

Results: Based on institutional expert consensus, a simulation procedural checklist was created with a minimum passing score set at correctly performing 30 of 31 items. On pre-test, no learners achieved the minimum passing score (22.5, interquartile range [IQR] 17.0-23.0). Initial post-test score for all learners was 30 (IQR 29.8-31.0). Six learners required additional attempts to reach mastery as defined by reaching the minimum passing score. Quiz scores significantly improved from 9 to 11 (pre-test IQR 9-10; post-test IQR 10-11; p < .05). Confidence in procedure significantly improved (pre-test 2.7/5.9, IQR 2.2-3.8; post-test 4.1/5.0, IQR 3.7-4.5; p < .01). Likelihood to perform procedure in future practice did not change (pre-test 2.2, IQR 1.0-3.8; post-test 3.0, IQR 1.0-4.0; p = .89).

Conclusion: SBML is an effective tool to improve multiple domains of learning in PM&R residents.
