ASSOCIATION BETWEEN POLYPHARMACY USE AND THE OCCURRENCE OF FALLS IN NON-INSTITUTIONALISED ELDERLY PEOPLE
Polypharmacy; Health of the elderly; Prevalence; Primary health care.
Introduction: The elderly population faces a triple burden of disease, predominantly chronic non-communicable diseases that require continuous treatment. Polypharmacy, characterized by the simultaneous use of five or more drugs, is increasingly common in this age group. Objective: To estimate the occurrence of falls and their association with polypharmacy use in the elderly. Method: This is divided into two studies: 1) an integrative literature review and 2) a cross-sectional study with multiple analyses of the factors associated with the occurrence of falls in the elderly, carried out from September to November 2023, in a municipality in the northeast of Brazil. Results: Article 1 - Brazil contributed with three publications and China, Thailand, Spain, and Italy, each with one publication respectively, in which 468,880 people using polypharmacy participated. Polypharmacy was more frequent in elderly people being treated for chronic diseases, especially systemic arterial hypertension (SAH) and diabetes mellitus, which were described in 71.4% of the studies. The frequency of polymedication in elderly people being monitored in primary health care ranged from 18.8% to 100.0%. The most commonly used drugs were for the cardiovascular and metabolic systems. Article 2 - The study involved 100 elderly people aged between 60 and 93, 68% female. The prevalence of falls was 42% and the factors associated with falls were polypharmacy, poor handgrip strength, and age 75. 61% of participants had one or more chronic diseases. Conclusion: Elderly people in polypharmacy require greater attention and care to prevent adverse events such as falls. The research data revealed that the prevalence of falls in the elderly was positively associated with polypharmacy, poor handgrip strength, and being 75 years old.
