Background: Due to limited systematic integration of health equity and implementation science, it is imperative to provide researchers and practitioners tools to guide implementation in settings where there is inequitable implementation of an intervention. Our prior work documented and piloted the first published adaptation of an existing implementation science framework with health equity determinants to create the Health Equity Implementation Framework. We suggested how othersâ might adapt their preferred implementation science frameworks with three health equity domains: 1) cultural factors of recipients, 2) clinical encounter, or patient-provider interaction, and 3) societal influences (including but not limited to social determinants of health). This manuscript is a practical guide to utilize three health equity domains in implementation research and practice.Methods: We describe in greater depth than in our previous publication domains typical in implementation determinants frameworks and three adaptations: domains known to affect health equity. For each domain, we compiled definitions with supporting literature, defined relevant subdomains, showcased an illustrative example, and suggested sample measures, both quantitative and qualitative.Results: We describe how to incorporate the three health equity domains in oneâs preferred implementation science framework, or how to use the Health Equity Implementation Framework specifically. Practical guidelines follow ten published recommendations on how to use frameworks in implementation research and practice. We describe a new case study in which the framework guided evaluation.Conclusions: Incorporating health equity domains within implementation frameworks may optimize the scientific yield and equity of implementation efforts by assessing and ideally, addressing, implementation and equity barriers simultaneously. The practical guidance and tools provided can assist implementation scientists and practitioners to concretely address inequity in implementation across populations to capture and analyze information used to assess health outcomes.Contributions to the LiteratureSpecific definitions of implementation and three health equity domains with examples of how they have been applied in published literature and sample measures.Practical tools, including a qualitative interview guide and codebookCase study of how the Health Equity Implementation Framework guided analysis in an implementation study
