Discrepancies in patients' medication lists from pharmacies in Sweden: an interview study before the implementation of the Swedish National Medication List

Abstract

BackgroundDiscrepancies in medication lists are common and can contribute to drug-related problems. This study was performed before the implementation of the National Medication List in Sweden, an intervention expected to improve the accuracy of medication lists.AimThe aim of the study was to examine the number and type of discrepancies in the medication list from pharmacies in Sweden. The secondary aim was to describe the information sources Swedish patients used as their medication lists and how confident they were with the information.MethodStructured interviews were conducted with patients at 13 community pharmacies in Sweden during the period October 5, 2020, to April 16, 2021. The printed medication list was reviewed together with the patient to identify any discrepancies and missing information.ResultsA total of 327 patients were included in the study (response rate 51%). The printed medication list from pharmacies was the most common information source for patients to know which medications to use. Two thirds (n = 215) of the patients had at least one discrepancy among their prescriptions and 32% (n = 106) were missing at least one prescription medication. Among all prescriptions (n = 2567) 10% (n = 264) were non-current prescriptions, 9% (n = 238) were duplicates and 3% (n = 88) had the wrong dose. The proportion of prescriptions with discrepancies differed between drug-groups.ConclusionThe discrepancies described in this study can have serious consequences, and results provide a baseline for studies after the implementation of the National Medication List.
