Primary Health Care

Primary health care is the accessible, community-based foundation of a health system and usually provides people's first contact with organised health services. It combines health promotion, disease prevention, basic treatment, rehabilitation and palliative support, while coordinating care across higher levels. It is broader than merely treating minor illness at a primary-level facility.

Functions at the primary level

Primary health care addresses most common health needs near where people live, thereby making care timely, continuous and affordable.

• It provides health promotion and disease prevention through health education, immunisation, screening, nutrition support and sanitation-related action.
• It offers basic diagnosis, treatment, maternal and child health services, essential medicines and follow-up for communicable and non-communicable diseases.
• It maintains continuity of care across the life course and supports rehabilitation, geriatric care and palliative care.
• Its community orientation enables early detection of outbreaks, local health planning and action on social and environmental determinants of health.

Link with secondary and tertiary care

Within a tiered system, primary care manages common and uncomplicated conditions, while secondary care provides specialist and hospital services and tertiary care handles highly specialised or complex cases.

• Primary facilities identify cases requiring advanced investigation or treatment and send them through an appropriate referral system.
• Counter-referral and follow-up allow patients returning from hospitals to receive medicines, monitoring and rehabilitation near their homes.
• Effective referral reduces avoidable congestion and costs at higher facilities, but requires reliable transport, records, diagnostics and adequately staffed hospitals.

Place in India's public health architecture

In rural India, Sub-Centres and Primary Health Centres form the principal primary-level network, while Community Health Centres function as referral institutions with specialist services. The National Health Policy, 2017 gives priority to comprehensive primary care and proposes allocating at least two-thirds of government health expenditure to primary care.

• A strong primary tier advances equity because remote, poor and vulnerable populations are least able to bear travel and hospital costs.
• By preventing disease and treating it early, primary care improves population health and reduces unnecessary demand for expensive hospital care.
