Primary health care is a whole-of-society approach to health and well-being centred on the needs and preferences of individuals, families and communities. It addresses the broader determinants of health and focuses on the comprehensive and interrelated aspects of physical, mental and social health and wellbeing.Development Committee' was established in 1943 under the chairpersonship of Sir Joseph Bhore. India started setting up primary health centres (PHCs) in 1952, when the first few PHCs were established in Najafgarh (Delhi), Singur (West Bengal) and Poonammalle (Tamilnadu) under Community Development Program. This was part of establishing a three-tier healthcare system in the country, which has evolved since then.
