AimMedication errors may occur at any stage during the medication process and can lead to preventable adverse drug events and patients' harm. Pharmacists' support for reconcilable medication has been shown to be effective, rectifying errors and inaccuracies of the drug treatment and in the increase of medication safety. However, none of the previous studies focused on vascular patients. We investigated the nature and frequency of drug-related problems (DRPs) including the amount of potentially inappropriate medication (PIM) prescribed for elderly patients suffering from vascular diseases and the influence of pharmacists in the improvement of cardiovascular medication.MethodsAfter the patients' routine admission process, medication reconciliation was performed. Therefore, a pharmacist obtained an accurate medication use history. The patients' drug therapy was critically screened for DRPs and referring to this, intervention was made by the pharmacist and communicated to the physician if necessary. Potentially inappropriate medication in the elderly was reviewed through a retrospective analysis using the Priscus-List. DRPs were documented anonymously and classified.ResultsWe identified 138 DRPs among 105 patients. Sixty-five patients experienced at least 1 DRP, accordingly 1.3 DRPs per patient. In total, 43 unintended discrepancies between current medication and admission medication were detected with an overall rate of 0.41 per patient; 100 interventions were made of which 56 resulted in explicit recommendations for prescription changes. Drug classes frequently affected by DRPs were antihypertensive in 23.9%, antithrombotic agents in 19.3% and lipid lowering agents in 12.1%. In a retrospective analysis of the home medication, 12 definite PIM were identified in 49 elderly patients.ConclusionDRPs are common in the medication of vascular surgery patients and may be improved by pharmacists.
