Clinical pharmacy in hospital palliative medicine: non-randomised clinical trial

To assess the impact of pharmaceutical care on hospital indicators and clinical outcomes of palliative care (PC) patients admitted to a secondary hospital.

A non-randomised clinical trial was carried out in the PC ward of a secondary hospital in São Paulo, Brazil. Pharmaceutical care for all patients aged 18 and above, admitted between October 2021 and March 2022, with stays exceeding 48 hours, was provided. The interventions required were performed in collaboration with healthcare teams, patients and caregivers. Assessments occurred at admission and discharge, using PC performance scales and pharmacotherapy tools, with Research Ethics Committee approval.

Over 6 months, 120 hospitalisations were analysed, primarily involving women (58.9%), averaging 71.0 years, with neoplasm diagnoses (20.5%). A total of 170 drug-related problems were identified in 68.3% of patients. Following assessment, 361 interventions were performed, with a 78.1% acceptance rate, including medication dose adjustments, additions and discontinuations. Addressing unintentional pharmacotherapy discrepancies at admission led to reduced hospital stays (p<0.05). Pharmaceutical interventions also decreased pharmacotherapy complexity (p<0.001), inappropriate medications for the older people (p<0.001) and improved symptom management, such as pain (p<0.05).

Pharmaceutical care services integrated within the multiprofessional health team contributed to reducing drug-related problems associated with polypharmacy as well as improved the management PC symptoms in end-of-life patients, which reduced hospitalisation time.
