Effects of home medication review on drug-related problems and health-related quality of life among community-dwelling older adults in China

Background: There is a lack of research on the nature of drug-related problems (DRPs) in older adult communities in China and the impact of home medication review on DRP reduction and health-related quality-of-life (HRQoL) improvement. Objectives: To identify and categorize DRPs in older adults in China and to assess the impact of home medication review. Methods: The prospective study was conducted in 2 community health service centers in Shanghai, China from December 2018 to December 2019. Eligible patients received a home medication review by a clinical pharmacist to assess for DRPs and adherence, propose pharmaceutical interventions, and measure outcomes of HRQoL. All enrolled patients were followed up for 3 months. Results: Medication use in 412 patients was analyzed. A total of 362 DRPs were identified, an average of 0.88 per patient. Treatment effectiveness was the primary DRP type (249; 68.8%). The most common causes of DRPs were patient-related (35.1%) and drug selection (31.0%). Pharmacists made 733 interventions, an average of 2 per DRP. A total of 82.1% of these interventions were accepted. At a 3-month follow-up, home medication review led to a statistically significant reduction in the mean number of DRPs (0.4 vs. 0.88, P < 0.001) and an increase in medication adherence (1.42 vs. 0.85, P < 0.001). Both HRQoL indicators also improved, EuroQol 5 Dimension scale (0.75 vs. 0.78, P < 0.001) and EuroQol-visual analog scale (70 vs. 77.65, P < 0.001). Conclusion: Home medication review is a practical means to optimize drug therapy and improve patients' HRQoL in community settings. (C) 2022 American Pharmacists Association (R).
