Structure of India’s Primary Health Care System: From National to Village Level

India runs one of the largest public health systems in the world, stretching from policy desks in Delhi to a single ASHA worker walking through a village in West Bengal. Understanding how this system is structured matters because it explains why a pregnant woman in a remote hamlet can still get an antenatal check-up, and why a national programme on tuberculosis eventually translates into a tablet handed out at a sub-centre. The primary health care system is built as a pyramid with four broad tiers, national, state, district, and community, each with defined roles, staff, and responsibilities.

The national level: Setting the direction 🔗

At the top sits the Union Ministry of Health and Family Welfare (MoHFW), headquartered at Nirman Bhawan in New Delhi. It is headed by a cabinet minister, supported by ministers of state, with the administrative work led by a Secretary to the Government of India. The ministry does not run hospitals directly; instead, it formulates national health policy, designs flagship programmes, allocates funds, sets technical standards, and coordinates with states, international agencies, and research bodies.

Departments within the ministry 🔗

Since the 2014 reorganisation, the MoHFW is composed of two main departments, the Department of Health and Family Welfare and the Department of Health Research. The Department of Health and Family Welfare handles awareness campaigns, immunisation, preventive medicine, public health programmes, and family welfare activities related to reproductive health, maternal health, and rural health services. The Department of Health Research, which oversees the Indian Council of Medical Research (ICMR), supports biomedical research and disease surveillance. A separate Ministry of AYUSH, carved out in 2014, looks after Ayurveda, Yoga, Unani, Siddha, and Homoeopathy systems.

Key technical and regulatory bodies 🔗

Attached to the ministry is the Directorate General of Health Services (DGHS), which provides technical advice on medical and public health matters and helps implement health programmes. The National Health Authority runs Ayushman Bharat – Pradhan Mantri Jan Arogya Yojana and the Ayushman Bharat Digital Mission. Other important bodies include the National Institute of Health and Family Welfare (NIHFW), the National Centre for Disease Control (NCDC), and the Indian Pharmacopoeia Commission, which since 1955 publishes the Indian Pharmacopoeia to set drug standards.

Core functions at the national level 🔗

The ministry’s main jobs include framing the National Health Policy, running centrally sponsored schemes like the National Health Mission, regulating medical education through bodies like the National Medical Commission and the Indian Nursing Council, and coordinating responses to disease outbreaks. It also represents India at the World Health Organization and partners with UNICEF and other global agencies to align with international health commitments.

The state and regional level: Adapting national policy to local realities 🔗

Health is a State subject in the Indian Constitution, with some areas placed on the Concurrent List. This means that while the Centre frames broad policy, each State and Union Territory designs and delivers most of its own health services. The result is real variation: Tamil Nadu and Kerala run mature, well-funded systems, while several northern and north-eastern states are still building basic infrastructure.

The State Department of Health 🔗

Every state has a Department of Health and Family Welfare led politically by a state Health Minister and administratively by a Health Secretary or Principal Secretary. Below the secretariat is the Directorate of Health Services, headed by a Director, which translates policy into action. The directorate plans state-wide schemes, manages district health offices, oversees state-run hospitals and medical colleges, and channels funds from the Centre under schemes like the National Health Mission.

Regional and zonal arrangements 🔗

Many larger states add an intermediate regional or zonal tier between the state headquarters and the districts. This is usually called a Regional Deputy Directorate or zonal office, supervising a group of districts on behalf of the state. The structure differs across states. Maharashtra, for example, organises health services into circles and divisions; Uttar Pradesh uses regional joint directors; some smaller states skip this layer entirely. State governments also independently appoint personnel for sub-centres and primary health centres, with their salaries borne by the state, which is why staffing patterns and pay scales can differ noticeably from one state to another.

The district and taluka level: Where planning meets delivery 🔗

The district is the workhorse of India’s health system. Most actual planning, supervision, procurement, and implementation happens here. A typical district covers a population of one to several million people, and the Chief Medical and Health Officer (CMHO), sometimes called the Chief Medical Officer or District Health Officer, leads the entire district health administration.

The district health team 🔗

The CMHO is supported by Additional or Deputy CMHOs and a set of programme officers responsible for specific national programmes, such as the District Tuberculosis Officer, District Malaria Officer, District Leprosy Officer, District Immunisation Officer, and Reproductive and Child Health Officer. The district hospital sits at the apex of the district’s curative services, providing specialist care, surgery, emergency services, and acting as the final referral point within the district.

Sub-divisional and taluka setups 🔗

Below the district are sub-divisions and talukas (also called tehsils or blocks). A sub-divisional hospital serves several blocks, providing intermediate specialist care. At the block level sits the Community Health Centre (CHC), which is the critical bridge between the highly visible district hospital and the village-level facilities people see every day. As per the Indian Public Health Standards revised in 2022, a CHC typically has 30 beds and is staffed with specialists in medicine, surgery, paediatrics, and obstetrics and gynaecology, plus diagnostic and emergency services. Each CHC functions as a First Referral Unit for around four PHCs and is a key site for institutional deliveries, blood storage, and the implementation of national disease control programmes.

Linking higher and lower tiers 🔗

The district level is where vertical reporting lines and horizontal coordination meet. District officers receive guidelines and funds from the state, transmit them to block-level facilities, and collect data flowing upward from sub-centres and PHCs. A District Health Society, set up under the National Health Mission, brings together health officials, the district administration, and Panchayati Raj representatives to plan and monitor activities. The same body oversees ASHA selection, supervision, and grievance redressal in many states.

The community level: Sub-centres, PHCs, and frontline workers 🔗

The community tier is where the system actually touches the people it is meant to serve. India’s rural health infrastructure follows a three-tier sub-structure under the district: the sub-centre, the primary health centre (PHC), and the community health centre (CHC). Under Ayushman Bharat, sub-centres and PHCs are progressively being upgraded into Ayushman Arogya Mandirs (formerly Health and Wellness Centres) to deliver an expanded package of comprehensive primary care, including non-communicable disease screening, mental health, and elderly care.

Sub-centres: The first contact 🔗

The sub-centre is the most peripheral institution and the first point of contact between the public health system and the community. Current norms place one sub-centre per 5,000 population in the plains and per 3,000 in tribal, hilly, or desert areas. Each sub-centre is staffed by one or two Auxiliary Nurse Midwives (ANMs) and a Male Health Worker, sometimes called a Multi-Purpose Worker. Sub-centres deliver services in maternal and child health, family planning, immunisation, control of communicable diseases, nutrition counselling, and basic curative care. Under the National Health Mission, each sub-centre receives an untied fund for local needs, jointly operated by the ANM and the village panchayat head.

Primary Health Centres (PHCs) 🔗

The PHC is the cornerstone of rural health services and the first port of call to a qualified doctor in the public sector. A PHC typically covers a population of 30,000 in the plains and 20,000 in hilly or tribal areas, and acts as the referral unit for about six sub-centres. It is usually staffed by one or two medical officers, a pharmacist, staff nurses, a lab technician, and support staff, and increasingly with a Community Health Officer for the Health and Wellness Centre component. PHC services cover outpatient care, antenatal and postnatal care, immunisation, family planning, treatment of common illnesses, basic laboratory tests, and referral to higher facilities. Many PHCs now offer 24×7 delivery services and basic emergency care.

Village-level health workers 🔗

The most visible face of the system in any village is the Accredited Social Health Activist (ASHA), introduced in 2005 under the National Rural Health Mission. An ASHA is a local woman, typically with at least eight years of schooling, chosen by the community for every 1,000 people in rural areas and every habitation in tribal regions. She is not a salaried employee but receives performance-linked incentives. Her tasks include mobilising pregnant women for antenatal check-ups and institutional deliveries, accompanying them to facilities, promoting immunisation, distributing oral rehydration salts, iron-folic acid tablets, and contraceptives, supporting tuberculosis treatment under DOTS, and counselling families on hygiene and nutrition.

Working alongside the ASHA are the Anganwadi Worker (AWW), who runs the village Anganwadi centre under the Integrated Child Development Services scheme of the Ministry of Women and Child Development, and the ANM, who visits the village regularly from the sub-centre. Together, ASHAs, ANMs, and AWWs form the trio of frontline workers who deliver the bulk of community-level primary care, supported by traditional birth attendants and Village Health, Sanitation and Nutrition Committees set up under the gram panchayat.

How the tiers connect 🔗

The strength of this pyramid lies in the linkages between its tiers. Information from village registers flows upward to sub-centres, PHCs, district health offices, the state directorate, and finally to the national Health Management Information System. Patients move in the opposite direction through a structured referral chain, from sub-centre to PHC to CHC and on to the district hospital or a medical college as the condition demands. Funds, medicines, and vaccines are procured at the central or state level and pushed down to the point of use, while supervision and training cascade from senior officers to frontline workers. When this chain works smoothly, an ASHA in a small village becomes part of the same system that shapes policy in Nirman Bhawan.

What do you think? Which tier of this system do you think is most under-resourced in your own state, and what would be the single most useful change to make the link between a village ASHA and the district hospital stronger?
