OBJECTIVE
This study evaluated the impact of a simulation-based mastery learning (SBML) curriculum on central line maintenance and care among a group of ICU nurses.
METHODS
The intervention included 5 tasks: (a) medication administration, (b) injection cap (needleless connector) changes, (c) tubing changes, (d) blood drawing, and (e) dressing changes. All participants underwent a pretest, engaged in deliberate practice with directed feedback, and completed a posttest. We compared pretest and posttest scores and assessed correlations between demographics, self-confidence, and pretest performance.
RESULTS
The number of nurses passing each task at pretest varied from 24 of 49 (49%) for dressing changes to 44 of 49 (90%) for tubing changes. At pretest, scores ranged from a median of 0.0% to 73.1%. At posttest, all scores rose to a median of 100.0%. Total years in nursing and ICU nursing had significant, negative correlations with medication administration pretest performance (r = -0.42, P = .003; r = -0.42, P = .003, respectively).
CONCLUSION
ICU nurses displayed large variability in their ability to perform central line maintenance tasks. After SBML, there was significant improvement, and all nurses reached a predetermined level of competency.
目的
本研究评估了基于模拟的掌握学习（SBML）课程对一组重症监护病房（ICU）护士中心静脉导管维护与护理的影响。
方法
干预包括5项任务：（a）给药，（b）更换注射帽（无针连接器），（c）更换管路，（d）采血，以及（e）更换敷料。所有参与者都进行了预测试，在有针对性的反馈下进行刻意练习，并完成了后测试。我们比较了预测试和后测试的分数，并评估了人口统计学、自信心和预测试表现之间的相关性。
结果
预测试时通过每项任务的护士人数从更换敷料的49人中的24人（49%）到更换管路的49人中的44人（90%）不等。预测试时，分数范围从中位数0.0%到73.1%。后测试时，所有分数均升至中位数100.0%。护理总年限和ICU护理年限与给药预测试表现呈显著负相关（分别为r = -0.42，P = .003；r = -0.42，P = .003）。
结论
ICU护士在执行中心静脉导管维护任务的能力上表现出很大差异。经过SBML后，有显著改善，所有护士都达到了预定的能力水平。
