Describe structure and function of Primary Health Care (PHC) system in India.

The Primary Health Care (PHC) system in India is a foundational element of the country’s healthcare framework. PHC is critical to the overall health and development of the nation, providing accessible, affordable, and essential health services to all sections of the population, especially those in rural and underserved areas. The concept of Primary Health Care (PHC) was introduced globally in 1978 at the Alma-Ata Declaration by the World Health Organization (WHO), and India embraced this model to address its health challenges. Over the years, the structure and function of the PHC system in India have evolved to meet the needs of the population. This system is designed to be the first point of contact for individuals and communities with the health system, ensuring comprehensive, equitable, and continuous care.

Structure of Primary Health Care in India

The structure of PHC in India is designed to provide a network of healthcare services at various levels, beginning at the grassroots and moving upward. The system is organized into three main tiers: the Sub-Center, Primary Health Center (PHC), and Community Health Center (CHC), each serving distinct purposes.

1. Sub-Center (SC): Sub-centers are the first point of contact between the healthcare system and the rural population. They are the most peripheral units and are typically situated in rural areas. A sub-center serves a population of about 3,000 people in the plain area and 1,500 people in hilly or tribal areas. The main functions of a sub-center include maternal and child health services, immunization, family planning, and basic health education. Each sub-center is typically staffed by one Auxiliary Nurse Midwife (ANM) ___ _____ ______ ________ ______ ___ _____ _______.
