Impact of 4 Components of Instructional Design Video on Medical Student Medical Decision Making During the Inpatient Rounding Experience.

The Four Components of Instructional Design (4C-ID) Model has been used to teach Medical Decision Making (MDM), a core competency recognized by the Liaison Committee for Medical Education. 4 Components of Instructional Design (4C-ID) has been applied in general medical education, but not the inpatient clerkship setting. A 4C-ID video for inpatient rounding, like postpartum rounding in Ob/Gyn, could help improve MDM on busy services. Students in the third year Ob/Gyn clerkship were randomized by clerkship group to receive a 20-minute postpartum rounding video, based on 4C-ID principles, or usual teaching. MDM and knowledge were assessed pre-/postintervention with the Diagnostic Thinking Inventory and a case-based evaluation. Satisfaction was assessed with Likert style questions. Seventy-eight students were randomized (36 control, 42 intervention). Both groups had equal baseline measures of MDM and knowledge, and similar postclerkship MDM. The intervention group demonstrated higher knowledge postclerkship (17.1, 22.6 p < 0.001). Students in the intervention felt prepared by the video, and would recommend it. Students in the control group reported higher satisfaction with their postpartum rounding experience (3.9, 3.5 p = 0.04). Videos are easy to incorporate teaching platforms for medical students, however, the 4C-ID based video in this study did not increase student MDM. In addition, educators should use caution when integrating video into coursework as use of video may lead to decreased student satisfaction as it did in this study.
