Background: No recognized standards exist for teaching patients and their caregivers ventricular assist device (VAD) self-care skills. We compared the effectiveness of a VAD simulation-based mastery learning (SBML) self-care training curriculum with usual VAD self-care training.
Methods and results: VAD patients and their caregivers were randomized to SBML or usual training during their implant hospitalization. The SBML group completed a pretest on 3 VAD self-care skills (controller, power source, and dressing change), then viewed videos and participated in deliberate practice on a simulator. SBML participants took a posttest and were required to meet or exceed a minimum passing standard for each of the skills. The usual training group completed the existing institutional VAD self-care teaching protocol. Before hospital discharge, the SBML and usual training groups took the same 3 VAD self-care skills tests. We compared demographic and clinical information, self-confidence, total participant training time, and skills performance between groups. Forty participants completed the study in each group. There were no differences in demographic and clinical information, self-confidence, or training time between groups. More participants in the SBML group met the minimum passing standard compared with the usual training group for controller (37/40 [93%] versus 25/40 [63%]; P=0.001), power source (36/40 [90%] versus 9/40 [23%]; P<0.001), and dressing change skills (19/20 [95%] versus 0/20; P<0.001).
Conclusions: SBML provided superior VAD self-care skills learning outcomes compared with usual training. This study has important implications for patients due to the morbidity and mortality associated with improper VAD self-care.
