Physicians require extensive training to achieve proficiency in mechanical ventilator (MV) management of the critically ill patients. Guided self-directed learning (GSDL) is usually the method used to learn. However, it is unclear if this is the most proficient approach to teaching mechanical ventilation to critical care fellows. We, therefore, investigated whether critical care fellows achieve higher scores on standardized testing and report higher satisfaction after participating in a hands-on tutorial combined with GSDL compared to self-directed learning alone.
First-year Pulmonary and Critical Care Medicine (PCCM) fellows (=6) and Critical Care Internal Medicine (CCIM) (=8) fellows participated. Satisfaction was assessed using the Likert scale. MV knowledge assessment was performed by administering a standardized 25-question multiple choice pre- and posttest. For 2 weeks the CCIM fellows were exposed to GSDL, while the PCCM fellows received hands-on tutoring combined with GSDL.
Ninety-three percentage (6 PCCM and 7 CCIM fellows, total of 13 fellows) completed all evaluations and were included in the final analysis. CCIM and PCCM fellows scored similarly in the pretest (64% vs. 52%, =0.13). Following interventions, the posttest scores increased in both groups. However, no significant difference was observed based on the interventions (74% vs. 77%, =0.39). The absolute improvement with the hands-on-tutoring and GSDL group was higher than GSDL alone (25% vs. 10%, =0.07). Improved satisfaction scores were noted with hands-on tutoring.
Hands-on tutoring combined with GSDL and GSDL alone were both associated with an improvement in posttest scores. Absolute improvement in test and satisfaction scores both trended higher in the hands-on tutorial group combined with GSDL group.
医生需要经过广泛培训才能熟练掌握危重症患者的机械通气(MV)管理。指导性自主学习(GSDL)通常是学习所采用的方法。然而,目前尚不清楚这是否是向重症医学专科住院医师教授机械通气的最有效方法。因此,我们调查了与单纯的自主学习相比,重症医学专科住院医师在参加实践教程并结合GSDL后,在标准化测试中是否能取得更高分数,以及是否报告更高的满意度。
第一年的肺与重症医学(PCCM)专科住院医师(n = 6)和重症医学内科(CCIM)专科住院医师(n = 8)参与了研究。使用李克特量表评估满意度。通过进行一次标准化的25道选择题的前后测试来评估MV知识。CCIM专科住院医师接受了两周的GSDL,而PCCM专科住院医师接受了实践辅导并结合GSDL。
93%(6名PCCM专科住院医师和7名CCIM专科住院医师,共13名专科住院医师)完成了所有评估并纳入最终分析。CCIM和PCCM专科住院医师在预测试中的得分相似(64%对52%,P = 0.13)。干预后,两组的后测试得分均有所提高。然而,基于干预措施未观察到显著差异(74%对77%,P = 0.39)。实践辅导与GSDL组的绝对提高高于单纯GSDL组(25%对10%,P = 0.07)。实践辅导的满意度得分有所提高。
实践辅导结合GSDL和单纯的GSDL都与后测试得分的提高相关。实践教程结合GSDL组在测试和满意度得分上的绝对提高趋势更高。
