The universal health system (UHS) was considered a utopian idea in emerging markets until countries like India initiated its implementation. The UHS is not a new phenomenon with countries, such as Canada, Ireland and the UK, having implemented it many decades ago in their respective countries. This study revisits the entire literature on UHS till date. The extant literature analysis has resulted in five research themes and has highlighted the challenges faced during the implementation of UHS in India. The future research directions for academia and a conceptual framework of UHS implementation is also proposed. This study suggests that there is a need for more studies on policy paradigms, improving accessibility, funding models, healthcare grid, manpower mapping and audit metrics for achieving the goal of equitable UHS implementation in India.
