Abstract

Aim: To investigate the effects of a comprehensive medication review intervention on health-related quality of life (HRQoL) and clinical outcomes in geriatric outpatients exposed to polypharmacy. Methods: Pragmatic, nonblinded, randomized clinical trial with follow-up after 4 and 13 months. Participants were geriatric outpatients taking ≥9 medicines. The intervention was an additional consultation with a physician focusing on reviewing medication, informing patients about their medicines and increasing cross-sectoral communication as supplement to and compared with usual care. The primary outcome was change in HRQoL after 4 months measured with the EuroQoL 5-dimension 5-level (EQ-5D-5L) questionnaire. Secondary outcomes were HRQoL after 13 months, mortality, admissions, falls and number of medicines after 4 and 13 months. Results: Of 785 eligible patients, 408 were included (age: mean 80.6 [standard deviation 7.22] years; number of medicines: median 12 [interquartile range 10–14]; females 71%). After 4 months, the adjusted between-group difference in EQ-5D-5L index score was 0.066 in favour of the medication consultation (95% confidence interval 0.01 to 0.12, P =.02). After 4 months, two (1%) participants had died in the medication-consultation group and nine (4%) in the usual-care group (log-rank test, P =.045). The medication consultation reduced the number of medicines by 2.0 (15.8%) after 4 months and 1.3 (10.7%) after 13 months. There were no statistically significant differences in mortality or HRQoL after 13 months, and no differences in falls or admissions. Conclusions: An additional consultation with medication review and increased communication as supplement to usual geriatric outpatient care improved HRQoL and reduced mortality after 4 months.
