Medical clerkships do not reduce common prescription errors among medical students

Prescribing correctly represents one of the most essential skills of a doctor when it comes to patient safety. Unfortunately, prescribing errors still account for a large proportion of avoidable drug-related problems (DRP). Despite this shortcoming, many medical schools do not provide specific prescribing training and assume that students acquire sufficient prescribing skills during regular medical clerkships. We therefore investigated whether there is an association between the individual time spent by students in internal-medicine clerkships and the number of prescription errors committed in a standardized prescribing test for common drug-related problems in a medical inpatient setting. Seventy-four fifth-year medical students (25 ± 3 yrs, 24 m, 50 f) who had completed their formal pharmacology training filled in prescription charts for two standardized patient paper cases. The charts were rated by two blinded consultants from the field of internal medicine using a checklist for common prescription errors. Students were divided into three groups according to the number of weeks previously spent in internal-medicine clerkships. Group differences in the number of prescription errors made were subsequently examined. Students committed 69% ± 12% of all possible prescription mistakes. There was no significant difference between the group without clerkships in internal medicine (G1) (71 ± 9%), the group with one to four weeks (G2) (67 ± 15%), and the group with more than five weeks of clerkships (G3) (71 ± 10%), p = .76. Medical students do not seem to acquire the necessary skills to avoid common prescription errors during regular clerkships in internal medicine. This study provides evidence to suggest that specific prescription training within medical education is warranted in order to prevent DRP.
