Polypharmacy-related polypathology in the elderly: A case study at Ibn Sina Hospital, Morocco

Abstract

Purpose: To determine the polypathological and therapeutic profiles of a population of elderly subjects at the Ibn Sina Hospital, Rabat, Morocco. 
 Methods: This was a prospective cross-sectional observational study on a population made up of 356 patients aged ≥ 65 years. Data were collected from different departments during the study period, regarding age, sex, educational level, socio-cultural and economic status, self-care ability, polypathologies, polymedication, effectiveness of treatments, adverse effects, and knowledge of the concept of generic medication. The results, which are presented in percentages and simple averages, were processed with Excel 2016 software. 
 Results: Patients aged 66 - 75 years comprised 60.4 % of the studied population. The most common pathologies were diabetes, asthma, and cardiovascular disease. A total of 237 patients (66.6 %) took < 6 drugs, while 119 patients (33.4 %) were on polypharmacy, i.e., > 6 drugs. The elderly were more vulnerable to polypathology and polypharmacy due to age-related reduction in physiological functions and their impact on pharmacological parameters. Polypathology led to polypharmacy which increased the risk of side effects and problems with adherence to medications. 
 Conclusion: This study provides information on the pathological profiles of a population of elderly subjects in a Moroccan hospital, and details of the therapeutic strategies used in managing these patients.
