Abstract

Introduction: In Mexico, there are a limited number of studies on medication errors in rural communities or settings. Therefore, this study aimed to describe prescription errors detected during the dispensing process for outpatients of a second-level public hospital in a rural area of southeastern Mexico.

Method: A retrospective, cross-sectional study was conducted to analyze prescriptions made in four months. The detection of medication errors was through direct observation by the pharmacist after receiving the prescription of five services: General Medicine, Family Medicine, Internal Medicine, Pediatrics, and Dentistry. The errors were classified based on the updated document by the Ruiz-Jarabo 2000 working group.

Results: 2 024 prescriptions were made during the study period, and 94 (4,6%) errors were detected. Among the five departments, Pediatrics had the highest percentage of medication errors (8,3%), followed by Dentistry (4,4%), Internal Medicine (3,9%), Family Medicine (3,9%), and finally, General Medicine (1,4%). The most common types of medication errors included inappropriate medication, incorrect dosage, and incomplete/ambiguous written communication, followed by other types.

Conclusions: Medication errors are preventable, and more pharmacists are needed to manage drug dispensing processes and validate prescriptions in health care institutions to avoid unfavorable outcomes for patients’ health.
