The association between medication use and health-related quality of life in multimorbid older patients with polypharmacy.

Purpose: To explore the association between medication use-related factors and health-related quality of life (HRQoL) in older hospitalised multimorbid patients with polypharmacy.

Methods: This cross-sectional study used the intervention arm data of the OPERAM trial (hospitalised patients ≥ 70 years with polypharmacy). HRQoL was assessed using the visual analogue scale (EQ-VAS) and the EQ-5D index score of the EuroQol questionnaire (EQ-5D-5L).
