Medication-related factors associated with health-related quality of life in patients older than 65 years with polypharmacy.

Design: Cross-sectional descriptive study. Setting: Primary care. Participants: Patients older than 65 years who use multiple medications (n = 375). Measurements: The main outcome measure was health-related quality of life according to the EuroQol-5D instrument. Sociodemographic, clinical and medication-related variables were recorded during home interviews. Mean age was 74.72 ± 5.59 years, and 65.5% of our participants were women. The global level of health-related quality of life according to the EQ-5D visual analog scale was 59.25 ± 20.92. Of the five EuroQol dimensions, anxiety/depression and pain were the most frequently reported, while mobility and self-care were the dimensions with the greatest impact on self-reported quality of life. Multivariate analysis indicated that functional independence was the factor most strongly associated (β = 14.27 p < 0.001) with better health-related quality of life, while illiteracy (β = -13.58 p < 0.001), depression (β = -10.13 p < 0.001), social risk (β = -7.23 p = 0.004) and using more than 10 medicines (β = -4.85 p = 0.009) were strongly associated with a poorer health-related quality of life. Factors inherent within the patient such as functional incapacity, cognitive impairment and social and emotional problems were the main constraints to quality of life in our study population. The number of medicines taken was negatively related with quality of life.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Quality of lifeMedical risk factorsCognitive impairmentDrug therapyMental health and psychiatryDrug administrationGeriatric careDrug dependenceAgedAged, 80 and overFemaleGeriatric AssessmentHumansMalePolypharmacyQuality of LifeSelf ReportSurveys and Questionnairesresearch article28166266open accessCalidad de vida relacionada con la saludPolimedicaciónAncianosAtención primaria de saludFactores de riesgoMovilidadDepresiónAnsiedadDolorIndependencia funcional10.1371/journal.pone.01713201932-6203PMC5293190https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0171320&type=printablehttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC5293190/pdf
