The Association of American Medical Colleges defines recognition of the need for urgent or emergent escalation of care as a key Entrustable Professional Activity (EPA) for entering residency (EPA#10). This study pilots the use of an immersive virtual reality (VR) platform for defining objective observable behaviors as standards for evaluation of medical student recognition of impending respiratory failure.
A cross-sectional observational study was conducted from July 2018 to December 2019, evaluating student performance during a VR scenario of an infant in impending respiratory failure using the OculusRift VR platform. Video recordings were rated by 2 pair of physician reviewers blinded to student identity. One pair provided a consensus global assessment of performance (not competent, borderline, or competent) while the other used a checklist of observable behaviors to rate performance. Binary discriminant analysis was used to identify the observable behaviors that predicted the global assessment rating.
Twenty-six fourth year medical students participated. Student performance of 8 observable behaviors was found to be most predictive of a rating of competent, with a 91% probability. Correctly stating that the patient required an escalation of care had the largest contribution toward predicting a rating of competent, followed by commenting on the patient's increased heart rate, low oxygen saturation, increased respiratory rate, and stating that the patient was in respiratory distress.
This study demonstrates that VR can be used to establish objective and observable performance standards for assessment of EPA attainment - a key step in moving towards competency based medical education.
美国医学院协会将认识到需要紧急或加急升级护理定义为进入住院医师阶段的一项关键可托付专业活动(EPA)(EPA#10)。本研究试点使用沉浸式虚拟现实(VR)平台来定义客观可观察行为,作为评估医学生对即将发生的呼吸衰竭的识别能力的标准。
于2018年7月至2019年12月进行了一项横断面观察性研究,使用OculusRift VR平台评估学生在一名即将发生呼吸衰竭的婴儿的VR场景中的表现。录像由2组对学生身份不知情的医师评审员进行评分。一组对表现提供共识性的整体评估(不合格、临界或合格),而另一组使用可观察行为清单对表现进行评分。二元判别分析用于识别预测整体评估等级的可观察行为。
26名四年级医学生参与了研究。发现8种可观察行为的学生表现最能预测合格等级,概率为91%。正确指出患者需要升级护理对预测合格等级的贡献最大,其次是评论患者心率加快、血氧饱和度低、呼吸频率增加,以及指出患者处于呼吸窘迫状态。
本研究表明,VR可用于建立评估EPA达成情况的客观且可观察的表现标准——这是迈向基于能力的医学教育的关键一步。
