The All India Institutes of Medical Sciences (AIIMS) are a group of autonomous government public medical colleges of higher education. These institutes have been declared by an Act of Parliament as Institutes of National Importance.
AIIMS New Delhi, the fore-runner institute, was established in 1956. Since then, 22 more institutes were announced. As of January 2020, fifteen institutes are operating and eight more are expected to become operational until 2025. Proposals were made for six more AIIMS.
The first AIIMS was established in 1956 under the All India Institute of Medical Sciences Act, 1956. Originally proposed by the then Prime Minister of India Jawaharlal Nehru for establishment in Calcutta, it was established in New Delhi following the refusal of Chief Minister of West Bengal Bidhan Chandra Roy. The act established AIIMS New Delhi, which was then known simply as All India Institute of Medical Sciences, and gave it the Institutes of National Importance (INI) status.
