Ventricular assist device simulation-based mastery learning (SBML) results in better patient and caregiver self-care skills compared with usual training.
The aim of this study was to evaluate the effect of SBML on driveline exit site infections.
We compared the probability of remaining infection free at 3 and 12 months between patients randomized to SBML or usual training.
The SBML-training group had no infections at 3 months and 2 infections at 12 months, yielding a Kaplan-Meier estimate of the probability of remaining infection free of 0.857 (95% confidence interval [CI], 0.692-1.00) at 12 months. The usual-training group had 6 infections at 3 months with no additional infections by 12 months. Kaplan-Meier estimates of remaining infection free at 3 and 12 months were 0.878 (95% CI, 0.758-1.00) and 0.748 (95% CI, 0.591-0.946), respectively. Time-to-infection distributions for SBML versus usual training showed a difference in 12-month infection rates of 0.109 (P = .07).
Ventricular assist device self-care SBML resulted in fewer 12-month infections.
与常规培训相比，基于心室辅助装置模拟的精通学习（SBML）可使患者和护理人员的自我护理技能得到更好的提升。
本研究旨在评估 SBML 对驱动轴出口部位感染的影响。
我们比较了随机分配到 SBML 或常规培训的患者在 3 个月和 12 个月时保持无感染的概率。
SBML 培训组在 3 个月时无感染，在 12 个月时发生 2 例感染，Kaplan-Meier 估计 12 个月时无感染的概率为 0.857（95%置信区间[CI]，0.692-1.00）。常规培训组在 3 个月时有 6 例感染，在 12 个月时无进一步感染。Kaplan-Meier 估计的 3 个月和 12 个月时无感染的概率分别为 0.878（95% CI，0.758-1.00）和 0.748（95% CI，0.591-0.946）。SBML 与常规培训的感染时间分布显示，12 个月的感染率差异为 0.109（P =.07）。
心室辅助装置自我护理 SBML 可减少 12 个月时的感染。
