Introduction: Medication errors outside the hospital have been poorly studied despite representing an important threat to patient safety. Objective: To describe the characteristics of medication errors in outpatient dispensing pharmacists reported in a pharmaco-surveillance system between 2005 and 2013 in Colombia. Materials and methods: We conducted a descriptive study by reviewing and categorizing medication error reports from outpatient pharmacy services to a national medication dispensing company between January, 2005 and September, 2013. Variables considered included: process involved (administration, dispensing, prescription and transcription), wrong drug, time delay for the report, error type, cause and severity. The analysis was conducted in the SPSS ® software, version 22.0. Results: A total of 14,873 medication errors were reviewed, of which 67.2% in fact occurred, 15.5% reached the patient and 0.7% caused harm. Administration (OR=93.61, CI 95%: 48.510-180.655, p<0.001), dispensing (OR=21.58, CI 95%: 16.139-28.870, p<0.001), transcription errors (OR=5.64; CI 95%: 3.488-9.142, p<0.001), medicines for sensory organs (OR=2.04, CI 95%: 1.519-2.756, p<0.001), anti-infective drugs for systemic use (OR=1.99, CI 95%: 1.574-2.525, p<0.001), confusion generated with the name of the drug (OR=1.28, CI 95%: 1.051-1.560, p=0.014), and trouble interpreting prescriptions (OR=1.32, CI 95%: 1.037-1.702, p=0.025) increased the risk for error reaching the patient. Conclusions: It is necessary to develop surveillance systems for medication errors in ambulatory care, focusing on the prescription, transcription and dispensation processes. Special strategies are needed for the prevention of medication errors related to anti-infective drugs.
