This literature review aims to determine the relationship between the compliance of health workers washing hands and the incidence of nosocomial infections in hospitals. Methods: The method used in this article is a literature review using the PRISMA Approach. Journal databases from Science Direct, PubMed, and Google Scholar in the 2019-2023 time frame. Keywords "Handwashing," "Five Moments," and "Healthcare-Associated Infections (HAIS)" from the identification results based on inclusion criteria and eligibility review obtained ten articles for review. Results: The literature review study found that adherence to five moments of hand washing significantly affected the prevention of nosocomial infections.
