This article provides a thorough interpretation of the recommendations for implementation research in healthcare-associated infection (HAI) prevention and control, jointly issued by the Society for Healthcare Epidemiology of America, the Infectious Diseases Society of America, and the Association of Professionals in Infection Control and Epidemiology. The recommendations elaborate on the concepts, strategies, determinants, and evaluation methods of implementation research, as well as the commonly used theories, models, and frameworks (TMF) in the field of HAI prevention and control. By expounding on these TMF, this article aims to guide readers in deeply considering the scientific issues related to the implementation of hospital infection prevention and control, and to provide guidance on selecting and applying appropriate resources in specific environments and situations. The release of these recommendations aims to promote the implementation of evidence-based guidelines in medical institutions and ultimately achieve the goal of reducing the incidence of hospital infections by promoting and guiding the conduct of implementation research in the field of HAI prevention and control.
