| Abstract: | ObjectivesTo compare drugs prescribed on hospital admission with the list of drugs taken prior to admission for adult patients admitted to a cardiology unit and to identify the role of a pharmacist in identifying and resolving medication discrepancies.MethodThis study was conducted in a 300 bed university hospital in Brazil. Clinical pharmacists taking medication histories and reconciling medications prescribed on admission with a list of drugs used prior to admission. Discrepancies were classified as justified (e.g., based on the pharmacotherapeutic guidelines of the hospital studied) or unintentional. Treatments were reviewed within 48 hours following hospitalization. Unintentional discrepancies were further classified according to the categorization of medication error severity. Pharmacists verbally contacted the prescriber to recommend actions to resolve the discrepancies.ResultsA total of 181 discrepancies were found in 50 patients (86%). Of these discrepancies, 149 (82.3%) were justified changes to the patient''s home medication regimen; however, 32 (17.7%) discrepancies found in 24 patients were unintentional. Pharmacists made 31 interventions and 23 (74.2%) were accepted. Among unintentional discrepancies, the most common was a different medication dose on admission (42%). Of the unintentional discrepancies 13 (40.6%) were classified as error without harm, 11 (34.4%) were classified as error without harm but which could affect the patient and require monitoring, 3 (9.4%) as errors could have resulted in harm and 5 (15.6%) were classified as circumstances or events that have the capacity to cause harm.ConclusionThe results revealed a high number of unintentional discrepancies and the pharmacist can play an important role by intervening and correcting medication errors at a hospital cardiology unit. |
