ThinkTwenty (T20) India 2023 - Official Engagement Group of G20(2023)  Universal digital access to inclusive healthcare is a part of the G20’s vision to achieve Sustainable Development Goal-3 (good health and well-being), but the pathways to accomplish this are unspecified. India and other countries are in the process of extensively digitalising healthcare. This policy brief provides a roadmap to integrate the digital healthcare infrastructure for affordable, equitable, and universal access. The roadmap is presented using an ontology of universal digital access to inclusive healthcare. Policies related to universal digital access to inclusive healthcare must be based on the large number of pathways encapsulated in the ontology. The known effective pathways to universal digital access to inclusive healthcare must be reinforced, the known ineffective pathways must be redirected, and the unknown new pathways that must be discovered and explored.
