Drug Therapy Safety in Palliative Care—Pharmaceutical Analysis of Medication Processes in Palliative Care

Pharmacotherapy plays a crucial role in symptom management in palliative care and is associated with risks potentially leading to drug-related problems (DRP). Pharmacists can identify DRPs and advise prescribers on optimizing drug therapy. The aim of this study was to identify DRP in a palliative care unit (PCU) and evaluate corresponding pharmaceutical interventions. A non-randomized before-and-after study in a PCU starts with a control phase, an interphase, and an intervention phase. Primary endpoint: DRP, including pharmaceutical interventions and their acceptance. The medication of all inpatients was recorded at set time points, assessed for potential and manifest DRP, and categorized. In the control phase, the ward pharmacist did not interfere with the clinical team. In the intervention phase, the pharmacist could intervene when a DRP was identified and give recommendations. During the 12-month period, 284 patients were included (control phase n = 138; intervention phase n = 146) and 1079 DRPs were identified (control phase n = 634; intervention phase n = 445). The number of DRPs/patient was significantly reduced by the pharmacist’s interventions between the control and intervention phases (4 vs. 3 DRPs, p = 0.001). Overall acceptance of pharmaceutical interventions by prescribers was very high (227/256; 88%). DRPs are hardly preventable. With a clinical pharmacist as a member of the palliative care team, it is possible to reduce the number of DRPs and identify potential problems earlier.
