Mechanical ventilation (MV) management is an essential skill for pulmonary and critical care medicine (PCCM) fellows to master during training. The unprecedented emergence of the coronavirus disease (COVID-19) pandemic highlighted the need for advanced operator competency in MV to improve patients' outcomes.
We aimed to create a standardized case-based curriculum using a blended approach of high-fidelity simulation, rapid-cycle deliberate practice, video didactics, and hands-on small group sessions for rapid accumulation of knowledge and hands-on skills for PCCM fellows before caring for critically ill patients during the COVID-19 pandemic.
The MV curriculum consisted of the following steps: ) baseline written knowledge test with 15 multiple-choice questions covering MV, the latest evidence-based practices, and pathophysiology of COVID-19; ) baseline confidence survey using a 5-point Likert scale; ) a one-on-one session using a high-fidelity simulation manikin, a lung simulator, and a mechanical ventilator to test baseline competencies; ) a structured debriefing tailored per fellow's 50-point competency assessment checklist from the simulation using rapid-cycle deliberate practice; ) video didactics; ) a hands-on session in small groups for basic knobology, waveforms, and modes of MV; ) a one-on-one simulation reassessment session; ) a written knowledge posttest; and ) a post-training confidence survey using a 5-point Likert scale.
Eight PCCM fellows completed the training. The mean multiple-choice question score increased from 7.4 ± 2.9 to 10.4 ± 2.4 ( < 0.05), and the simulation scores increased from 17.1 ± 4.4 to 30.8 ± 3.7 ( < 0.05). Comparing the simulation reassessment to the baseline, fellows showed significant improvement ( < 0.05) in assessing indications for MV; implementing rapid sequence intubation for patients with COVID-19; initiating MV and ventilator bundle per best practices; recognizing and managing mucous plugging, ventilator dyssynchrony, and evidence-based treatments for acute respiratory distress syndrome; and developing a care plan for proning. The post-training survey revealed improved learner confidence in all competencies.
This pilot MV curriculum using a blended approach was feasible and allowed PCCM fellows to significantly improve their knowledge and hands-on skills, allowing for the appropriate use of MV during the pandemic. Self-reported improvement scores further reinforced this. The emergent need for novice learners may again be necessary for future pandemic settings where standard training models requiring extensive training time are limited.
机械通气(MV)管理是肺与重症医学(PCCM)专科培训学员在培训期间必须掌握的一项基本技能。冠状病毒病(COVID-19)大流行的空前出现凸显了提高MV操作技能以改善患者预后的必要性。
我们旨在采用高保真模拟、快速循环刻意练习、视频教学和实践小组讨论相结合的方法,创建一个标准化的基于案例的课程,以便PCCM专科培训学员在COVID-19大流行期间护理重症患者之前快速积累知识和实践技能。
MV课程包括以下步骤:1)进行15道多项选择题的基线书面知识测试,内容涵盖MV、最新的循证实践以及COVID-19的病理生理学;2)使用5点李克特量表进行基线信心调查;3)通过一对一课程,使用高保真模拟人体模型、肺模拟器和机械通气机来测试基线能力;4)根据学员在模拟中的50分能力评估清单,采用快速循环刻意练习进行针对性的结构化总结;5)视频教学;6)小组实践课程,内容涉及MV的基本操作、波形和模式;7)一对一模拟重新评估课程;8)书面知识后测;9)使用5点李克特量表进行培训后信心调查。
8名PCCM专科培训学员完成了培训。多项选择题的平均得分从7.4±2.9提高到10.4±2.4(P<0.05),模拟得分从17.1±4.4提高到30.8±3.7(P<0.05)。将模拟重新评估与基线进行比较,学员在评估MV指征、对COVID-19患者实施快速顺序插管、按照最佳实践启动MV和通气束、识别和处理黏液堵塞、通气不同步以及急性呼吸窘迫综合征的循证治疗,以及制定俯卧位护理计划等方面均有显著改善(P<0.05)。培训后调查显示,学员在所有能力方面的信心均有所提高。
这种采用混合方法的MV试点课程是可行的,使PCCM专科培训学员的知识和实践技能得到显著提高,从而能够在大流行期间合理使用MV。自我报告的改善分数进一步证实了这一点。对于新手学员的迫切需求,在未来标准培训模式所需培训时间有限的大流行环境中可能再次成为必要。
