RESUMO
INTRODUCTION: elderly frequently present a poly-pathology recurring polypharmacy. Therefore, strict medication adherence is essential to avoid poor health outcomes especially during health crises like the current COVID-19 pandemic. The aims of our study were to identify the predictors of medication non-adherence in elderly and to expose the role of the emergency department (ED) to improve the therapeutic adherence during COVID-19 pandemic. METHODS: it was a two steps study. Primary, an observational, prospective survey over one month, including 100 elderly patients consulting to the emergency department. Medication adherence was assessed by Morisky's 4-questions scale; predictors of non-adherence have been identified. Secondary, a report of elderly medication management by the emergency physicians during the COVID-19 pandemic confinement. RESULTS: first step: 100 patients, mean age of 73±8 years. The average number of drugs was 4±2. Medication non-adherence was reported in 39%, predictors of therapeutic non-adherence were: polypharmacy (OR=2.41; CI95% [1.60;3.61]), rural origin (OR=6.72; CI95% [1.47;30.63]) and metabolic diseases history (OR=5.24; CI95% [1.48;18.53]). In the second step, 816 elder lies were enrolled, mean age: 73±7 years. The therapeutic attitude in the emergency department was to prescribe the same treatment (60%) to adjust the doses of the drugs prescribed (14%) to stop one or more drugs (13%) or to indicate new treatments (13%). Thirty-five percent of patients were admitted for short-term hospitalization. CONCLUSION: medication non-adherence is common in elderly, due to several factors. During the COVID-19 pandemic, the emergency services in Tunisia played an important role in the follow-up and therapeutic continuity of these elderly patients.
