Abstract

INTRODUCTION: Medication errors cause adverse events in health care. OBJECTIVES: To characterize the medication process errors at Hospital Materno Infantil of Salta. METHODS: Errors were identified by pharmaceutical validation of prescriptions. Error rates were calculated, and associations between error and patient factors, drug treatment and human resource were determined. RESULTS: From November 1, 2012 to January 31, 2013 a total of 18 203 prescriptions were validated, identifying 2 989 (96.7%) errors of prescription, 79 (2.5%) of administration, 6 (0.2%) of transcription and 18 (0.6%) of dispensing. The error rate was 13.06 per 100 patient days for the Perinatology Area, with 30% of omission of doses and 23% of incorrect dose prescription. In the Pediatric Area, the rate was 8.6 per 100 patient days, with 55% of wrong doses, associated with child age. The pharmacotherapeutic groups involved were: non-steroidal anti-inflammatory drugs, digestive and circulatory system drugs, and anti-infectives. Most errors occurred with commonly used drugs, with potentially significant consequences for patients. The error rate was similar to doctors in training and permanent staff. CONCLUSIONS: Intensive pharmacovigilance allowed the identification of a large number of errors. Their characterization will permit to establish prevention strategies.
