Case-Based Teaching: Does the Addition of High-Fidelity Simulation Make a Difference in Medical Students’ Clinical Reasoning Skills?
Situativity theory posits that learning and the development of clinical reasoning skills are grounded in context. In case-based teaching, this context comes from recreating the clinical environment, through emulation, as with manikins, or description. In this study, we sought to understand the difference in student clinical reasoning abilities after facilitated patient case scenarios with or without a manikin.
Fourth-year medical students in an internship readiness course were randomized into patient case scenarios without manikin (control group) and with manikin (intervention group) for a chest pain session. The control and intervention groups had identical student-led case progression and faculty debriefing objectives. Clinical reasoning skills were assessed after the session using a 64-question script concordance test (SCT). The test was developed and piloted prior to administration. Hospitalist and emergency medicine faculty responses on the test items served as the expert standard for scoring.
Ninety-six students were randomized to case-based sessions with (n = 48) or without (n = 48) manikin. Ninety students completed the SCT (with manikin n = 45, without manikin n = 45). A statistically significant mean difference on test performance between the two groups was found (t = 3.059, df = 88, p = .003), with the manikin group achieving higher SCT scores.
Use of a manikin in simulated patient case discussion significantly improves students’ clinical reasoning skills, as measured by SCT. These results suggest that using a manikin to simulate a patient scenario situates learning, thereby enhancing skill development.
