The National Primary Health Care Development Agency (NPHCDA) is a parastatal of Nigeria’s Federal Ministry of Health. The agency was established in 1992 and merged with the National Programme on Immunization (NPI) in 2007. The NPHCDA was established following the recommendation of a high level WHO review team through Decree 29 of 1992 to capitalize on major achievements in primary health care delivery in Nigeria beginning from 1986 to 1992 which has resulted in the country being ranked amongst the top in the world in terms of primary healthcare, relative to other countries.
