Objective

Background BACKGROUND: Neuroanatomical localization (NL) is a key topic in Neurology. However, medical students often find NL intimidating and inadequately taught, with standard textbooks too cumbersome. To help medical students with NL, a concise, portable, one-page Precis for NL was developed. The Precis has been found to be user-friendly and helpful by third and fourth-year undergraduates at the Yong Loo Lin School Of Medicine (YLLSOM), National University of Singapore (NUS). However, the effectiveness of the Precis has not been assessed.

Design/Methods DESIGN/METHODS: We recruited second-year medical students undergoing the Neuroscience module at YLLSOM. They were first taught how to use both the Precis and the control (standard textbook NL algorithms) to perform NL in various clinical scenarios. Students were then randomly assigned into 2 groups - Precis or control. All participants then sat for a previously validated extended-matching questions (EMQ) test on NL, answering questions using only their assigned tool. The primary outcome was the difference in mean test scores in Precis versus control groups, expressed as a percentage of total score. The effect size was estimated using Cohen's d.

Results RESULTS: A total of 195 students were randomized to Precis (n=94) and control (n=101) groups; 194 answer scripts were analyzed as 1 answer script was not returned. Mean percentage scores were significantly higher for the Precis group compared to controls (42.5% vs 37.0%, p=0.014). The mean percentage difference in scores was 5.5% (95% CI 1.1 - 9.8); the effect size was 0.36.

Conclusions CONCLUSIONS: This randomized trial shows that the Precis was superior to standard textbook algorithms in assisting second-year students perform NL; effect size was modest. Our findings suggest that the Precis is effective in assisting NL in medical students.
