Popis: Background With increasing numbers of older multi-morbid people being exposed to polypharmacy, research needs to focus on medication-related outcomes affecting quality-of-life (QoL). This study examines older-patients’ medication-related QoL (MRQoL), its relationship to medication burden/complexity, frailty, health-related QoL (HRQoL) and potentially inappropriate medications (PIMs. Methods A cross-sectional-study was conducted in older-patients attending out-patients and day-hospital services of a tertiary-teaching-hospital. Participants were aged ≥65 years, first-time attendees, taking ≥5 chronic-medications for ≥3 chronic-conditions and mini-mental state examination score ≥26/30. Demographic, medication, comorbidity, frailty status, PIMs(STOPP/STARTv.2 criteria), MRQoL (MRQoL-LS v1.0) HRQoL (Short-form-12; SF-12) and medication burden (Living with Medicines Questionnaire v.2; LMQv2) data were collected. Drg compliance was measured using the Medication Adherence Rating Scale (MARS). Lower MRQoL-LS v1.0 scores indicate better MRQoL (range 0-84). Higher LMQv2 scores indicate higher medication burden (range from 60-300). A negative age-specific mean-difference score in SF-12 physical and mental health composite scale scores (SF12-PCS, SF12-MCS) indicates poorer health. Results Over 12 months, 234 patients (attending 78 clinics) were screened, 59 met inclusion criteria and 30 were recruited; 3 patients were subsequently identified as ineligible. Eighteen patients were female (66%), mean age was 79.4 years (SD±6.2), median number of daily medications was 10 (IQR 8-13), median number of comorbidities was 11 (IQR 9-14). Participants were generally drug-compliant, median MARS score of 9 (IQR 6.5-10). Patients’ median MRQoL score was 14 (IQR 14-22.5); mean LMQ v2 score was 115.64 (SD± 25.18). Mean age specific mean-difference SF12-PCS and SF12-MCS scores were -22.61 (SD±11.7) and -22.1 (SD±17.5) respectively. There was no significant correlation between MRQoL and number of daily medications, number of comorbidities, LMQ, HRQoL, or PIMs(Pearson’s 2-tailed test). Conclusion This study demonstrates that MRQoL-LS v.1 is not applicable to most patients attending geriatric ambulatory services. Furthermore, polypharmacy, multimorbidity, presence of PIMs poorer HRQoL do not correlate significantly with MRQoL.
