Examining potentially inappropriate medication use among elderly individuals in palliative care: A comprehensive study

This study aimed to evaluate the prevalence of polypharmacy, the presence of potentially inappropriate medications and related factors in older adults receiving palliative care. This cross-sectional descriptive study was performed in 213 patients who were served from palliative care services. Mini Nutritional Assessment-Short Form, Katz Activities of Daily Living Scale and Charlson Comorbidity Index were applied. Polypharmacy was defined as the use of 5 or more medicines while the use of 10 or more medicines was considered as hyper-polypharmacy. PIM was assessed according to the TIME-to START and TIME-to STOP criteria. A total of 213 patients were included, mean age was 78.00 ± 9.08 years. Polypharmacy was present in 59.2 % of the patients and hyper-polypharmacy was present in 10.8 %. There was a statistically significant correlation between polypharmacy and marital status, history of falls, mid-upper arm, and calf circumference (p = 0.017, p = 0.022, p = 0.010, p = 0.003, respectively). The rate of inappropriate medication use of the cardiovascular system, gastrointestinal system, analgesics, musculoskeletal system, and nervous system drugs was high. There was at least one inappropriate medication use in 56.3 % of older adults. PIMs use was 18.3 % according to TIME-to-START criteria and was 48.4 % according to TIME-to-STOP criteria. There was a higher rate of PIMs use according to TIME criteria in the group with polypharmacy than non-polypharmacy (p
