[Potentially inappropriate medication in older adults with palliative care at home]

Older adults with advanced chronic diseases and palliative care needs are more exposed to polypharmacy and use of potentially inappropriate medication, which generates a high risk of adverse events and impaired quality of life. The objective of this study was to describe the frequency of potentially inappropriate medication use among older adults with palliative care needs receiving home care services after hospital discharge.

Observational cross-sectional study of pharmacy dispensing and electronic health records, of older adults in a home care system and with palliative care needs according to the screening with the NECPAL tool or the PROFUND and/or PALIAR indexes. Dispensed medications during 180 days after admission to home care were analyzed. Medications were classified as potentially inappropriate according to the LESS-CHRON criteria.

We included 176 patients, mean age 87.4 years, 67% were women; 73% were pluripathologic patients and 22% had one chronic progressive disease. Mortality at 6 months was 73%. Median frequency of dispensed medications per patient was 9.1 (IQR = 4-9.7). The frequency of potentially inappropriate medication dispensation among patients was 87%, mainly antihypertensives, benzodiazepines and antipsychotics.

This study observed that dispensation of potentially inappropriate medication among older adults with palliative care needs and home care services is very high. This emphasizes the need for effective patient-centered interventions to prevent inadequate prescription and stimulate de-prescription.
