Teaching clinical reasoning among undergraduate medical students: A crossover randomized trial

Many clinical reasoning teaching techniques have been reported in the literature. The authors focused on 2 teaching techniques of clinical reasoning, the technique Summarize, Narrow, Analyze, Probe the preceptor, Plan, Self-selected topic (SNAPPS) and the Clinical Reasoning Technique (CRT), and compared their efficiency to improve the clinical reasoning competencies of third-year undergraduate medical students.

The authors performed a prospective randomized, controlled, non-blinded crossover trial including year-3 undergraduate medical students. Judgment criteria consisted of the scores attributed to a test assessing the cognitive competencies of the participants which was a structured summary performed by the students after each session. Besides, a satisfaction Likert-scale questionnaire was fulfilled by the students. Statistical analysis was performed using SPSS software (version 20.0).

Seventy-two students were included with a mean age of 21.03 (SD:2,30) years. The mean scores of the students allocated to the CRT arm reached 4.62 (SD:2.93)versus 4.99 (SD:2.93) for the SNAPPS arm. No significant statistical difference was observed between the mean scores according to the method used. The analysis of the satisfaction questionnaire revealed that 75% of the students preferred CRT because of the collaborative work performed.

This study highlights the need for varying techniques to improve the critical reasoning skills of medical students. Besides, it pointed out students' preference for collaborative approaches illustrating socio-constructivist theories of learning.
