Physician associations play a significant role in shaping health policy at national and subnational levels. However, the influence of such associations in low- and middle-income countries has not been synthesized or assessed. The Indian Medical Association (IMA), one of the largest physician associations in the world, has a long history of policy engagement at national and state levels across multiple issues. This review aims to assess—for the first time—the empirical literature available on the IMA as a political actor. Adopting a scoping review methodology, the paper sought to identify the policy stances, strategies, and influence of the IMA over India’s health policy. Nine health, social science, and policy research databases were searched for English-language studies published between 1974 and 2024. Reviewing 37 papers, it finds that the IMA has been active in seven main policy domains: violence against doctors; regulation of the private healthcare sector; restriction of traditional medicine; professional authority or autonomy for physicians; publicly funded health insurance; medical ethics; and partnership in public health programmes. It has been reactive against new legislation, reform or regulation in all domains except for violence against doctors. Through interrelated interior and exterior strategies, the organization has been successful in influencing, stalling or limiting legislation. While the IMA holds influence through the size of its membership and its embeddedness in health administration and corporate interests, the tactics of the organization often lack coherence and consistency. Situating these findings in the broader landscape of health governance, our review contributes further evidence for the need to develop more inclusive and transparent pathways for participation in decision-making.
