OBJECTIVE To assess reports of medication errors in hospitalized children to establish their frequency, causes, and adverse events(AEs). METHODS Prospective study of medication errors reported at the Neonatal Intensive Care Unit (NICU), Pediatric Clinic (PC), and Pediatric intensive Care Unit (PICU). Ambulatory Pediatrics reports and incomplete data were excluded. Related variables were evaluated. RESULTS Out of 989 errors reported in Department of Pediatrics, 401 (41 %) corresponded to medication errors. Of these, 353 (88 %) reached patients and 48 (12 %) were quasi-errors; 42 % occurred in the morning; 24 %, in the afternoon; 17 %, in the morning and afternoon, and 17 %, in the night; differences were not significant (p = 0.18). Dosing errors were the most common ones, 118 (33.4 %). In total, 160 reports (45 %) corresponded to prescription errors; 149 (42 %), to administration errors; and 44 (2.5 %), to dispensing errors. Dosing errors were more common in prescriptions (p < 0.05). The highest number of errors was reported at the NICU, 179 (50 %); compared to 91 (25.5 %) at the PC and 83 (24.5 %) at the PICU. A total of 91 AEs were reported (22.5 %); most were mild, 53 (58 %), or moderate, 31 (34 %). The NICU reported 53 AEs (58 %); the PICU, 25 (27 %); and the DCP, 18 (19.7 %). No deaths occurred. CONCLUSION The rate of medication errors reported in hospitalized children was 41 %. Dosing errors were the most common ones. A total of 91 AEs were reported; most were mild (58 %); the highest number was reported at the NICU (58 %).
