Medical students' errors in pharmacotherapeutics

Area of Science:

• Medical Education
• Pharmacotherapeutics
• Clinical Reasoning

Background:

• Prescribing errors are a significant concern in medical practice.
• Understanding the root causes of these errors is crucial for improving patient safety.
• Medical students require robust training in pharmacotherapeutics to ensure safe prescribing.

Purpose of the Study:

• To analyze prescribing errors made by final-year medical students.
• To identify the underlying reasons for non-optimal prescribing decisions.
• To inform improvements in pharmacotherapeutics training.

Main Methods:

• A classroom prescribing exercise involving 16 final-year medical students.
• Students adjusted phenytoin sodium dosage for a simulated patient case.
• Process-tracing and think-aloud techniques were employed to observe student performance.

Main Results:

• Lack of an integrated knowledge base (scientific knowledge + clinical know-how) was the primary cause of errors.
• Three clinical reasoning strategies were identified: incremental, gambling, and backward-reasoning.
• Incremental strategy correlated with superior scientific knowledge and less hazardous errors, while gambling and backward-reasoning strategies indicated inferior knowledge and more hazardous errors.

Conclusions:

• Integrating basic medical science with clinical know-how, as in problem-based learning, is supported.
• A strong foundation in medical science is essential for minimizing prescribing errors.
• Enhanced pharmacotherapeutics education is vital for future physicians.
