Primary health care serves as the bedrock of the Nigerian health system, designed to bring essential services as close as possible to where people live and work. It focuses on preventive, promotive, curative, and rehabilitative services. Rather than waiting for illness to strike, this level emphasizes community participation, health education, and maternal and child health. In the context of Nigeria, the primary health care system operates primarily at the Local Government Area level, bridging the gap between rural populations and higher tiers of healthcare.
The physical structure of primary healthcare in Nigeria is tiered to ensure progressive levels of care and supervision. It forms a pyramid starting from the community-based health posts up to comprehensive health centres. This tiered arrangement allows resources to be distributed efficiently, ensuring minor ailments are managed locally while complicated cases move upward.
The health post is the most basic and peripheral unit in the primary health care system, usually located in remote or rural settlements. Staffed typically by community health workers or trained volunteers, it provides rudimentary care such as treating minor cuts, distributing malaria treatments, and offering basic health education. It serves as the eyes and ears of the health system at the grassroots level.
Moving up the ladder, health clinics and health centres offer broader services than a basic health post. They are usually managed by Community Health Extension Workers (CHEWs) and sometimes staffed by a resident midwife or nurse.
At the apex of primary care delivery stands the Comprehensive Health Centre (CHC) or Model Primary Health Centre. These facilities are designed to provide twenty-four-hour services, including minor surgeries, comprehensive emergency obstetric care, and blood transfusion services. They feature resident doctors, midwives, nurses, and laboratory technicians, acting almost like small community hospitals.
A successful primary health facility relies on a multidisciplinary team. Midwives, nurses, CHEWs, environmental health officers, and pharmacy technicians work together. Midwives play a pivotal role in reducing maternal and neonatal mortality by managing normal pregnancies and recognizing danger signs early. Supervision by primary healthcare coordinators ensures standards are maintained across facilities.
No primary facility can operate in isolation. An effective referral system connects primary health centres to general or secondary hospitals when complications exceed local capabilities—such as obstructed labor requiring a Caesarean section. Proper referral communication, documentation, and transportation prevent delays that often lead to maternal or neonatal deaths.
