Polypharmacy in the elderly: A bibliometric and visualization analysis

Abstract

Background: The incidence of polypharmacy is increasing owing to population aging and the associated presence of multiple comorbidities. This study aimed to provide an extensive overview of the history and development of the scientific literature on polypharmacy. Methods: Data were gathered from the comprehensive Scopus database and assessed using various bibliometric methods, including analyses of citations, growth patterns, and key contributors in the field. Results: A notable upward trend in the publication rate of polypharmacy research was observed throughout the study period (1976-2022). Journal of the American Geriatrics Society emerged as the predominant platform for disseminating polypharmacy-related findings. Hughes CM from Queen’s University Belfast, the United Kingdom (UK), emerged as the most prolific author in this field. Most articles were authored by researchers affiliated with institutions in the United States (n=267), the UK (n=92), and Italy (n=72). Conclusion: This study provides compelling evidence of the escalating interest in polypharmacy and momentum in related research, highlighting the crucial publication-related aspects and indicators in this field. The findings underline the value of bibliometric analyses as a tool for healthcare professionals. The wide dissemination, influence, and visibility of polypharmacy research in reputable scientific journals emphasize the urgent clinical need for addressing polypharmacy concerns and encourage further exploration in this area.
