Quality of postpartum care (PPC) efforts to improve service delivery through additional training and supervision in 9 Health Centers (HCs) in Morogoro Region, Tanzania was evaluated by comparing with 9 none-intervention HCs for structural inputs; provider and client profiles; processes (PNC counselling) and outcomes (patient knowledge) through direct observations of equipment, supplies and infrastructure. Program training and supervision activities had a modest effect on the quality of PPC. Client perceptions about the value of PPC need to be changed; the content of recommended PPC messages reviewed along with the location for PPC services; gaps in the availability of human resources addressed; and increased provider-client contact encouraged.
