Mixed-methods education of mechanical ventilation for residents in the era of the COVID-19 pandemic: Preliminary interventional study

Abstract

Introduction In the current era of the severe acute respiratory syndrome-coronavirus-2 epidemic, the need for respiratory care, including mechanical ventilatory (MV) management, has increased. However, there are no well-developed educational strategies for training medical personnel dealing with respiratory care in MV management. Methods A novel mixed-methods hands-on seminar for learning MV management was conducted for the residents at Chiba University Hospital in March 2022. The seminar lasted approximately 2 hours. The learning goal for the residents was to develop skills and knowledge in performing basic respiratory care, including MV, during an outbreak of a respiratory infection. The seminar with a flipped classroom consisted of e-learning, including modules on respiratory physiology and MV management, hands-on training with a low-fidelity simulator (a lung simulator), and hands-on training with a high-fidelity simulator (a human patient simulator). The effectiveness of the seminar was evaluated using closed questions (scored on a five-point Likert scale: 1 [minimum] to 5 [maximum]) and multiple-choice questions (maximum score: 6) at the pre- and post-seminar evaluations. Results Fourteen residents at Chiba University Hospital participated in the program. The questionnaire responses revealed that the participants’ motivation for learning about MV was relatively high in the pre-seminar period (seven participants [50%] selected level 5 [very strong]), and it increased in the post-seminar period (all participants selected level 5) (p = 0.016). The responses to the multiple-choice questions revealed that the participants did not have enough knowledge to operate a mechanical ventilator, while the total score significantly improved from the pre- to post-seminar period (pre-seminar: 3.3 ± 1.1, post-seminar: 4.6 ± 1.0, p = 0.003). Conclusions The seminar implemented in this study helped increase the residents’ motivation to learn about respiratory care and improved knowledge of MV management in a short time. In particular, the flipped classroom may promote the efficiency of education on MV management.
