Primary healthcare is the backbone of India’s public health system. It is the first point of contact for individuals, families, and communities—especially in rural and remote areas where access to hospitals and specialists is limited. With more than 1.4 billion people, India faces unique healthcare challenges such as unequal access, high disease burden, and limited infrastructure in certain regions. To address these challenges effectively, the Government of India has launched various National Health Programs (NHPs) under the Ministry of Health & Family Welfare and the National Health Mission (NHM).
This comprehensive guide explains the concept of primary healthcare, its importance, India’s healthcare structure, and detailed coverage of the major national health programs implemented to improve public health outcomes.
🏥 What Is Primary Healthcare?
Primary healthcare (PHC) refers to essential healthcare services accessible at the community level. It includes preventive, promotive, curative, and rehabilitative services.
According to WHO, primary healthcare is based on:
- Universal access
- Public participation
- Health promotion
- Intersectoral coordination
- Use of appropriate technology
In India, primary healthcare operates through:
- Sub-Centers (SCs)
- Primary Health Centers (PHCs)
- Community Health Centers (CHCs)
These facilities ensure that healthcare reaches the grassroots level.
🌟 Objectives of Primary Healthcare in India
The major goals include:
