This study examined the integration of Community Health Residency Programmes into Primary Health Care (PHC) settings in Ondo City, Nigeria. The study focused on the level of integration, the contributions of residency programmes to PHC service delivery, and the challenges affecting effective implementation. A descriptive survey research design was adopted, and data were collected using structured questionnaires administered to 115 respondents comprising resident doctors, community health workers, caregivers, and health trainees. Data were analyzed using descriptive statistics of frequency counts, percentages, mean, and standard deviation. Findings revealed that Community Health Residency Programmes are moderately integrated into PHC settings, with resident doctors actively involved in routine PHC activities such as immunization, antenatal care, disease prevention, and health promotion. Specifically, the level of integration recorded mean scores ranging from 2.97 to 3.16, while contributions to PHC service delivery ranged from 3.15 to 3.30, indicating a strong positive impact. However, effective integration is hindered by inadequate funding (= 3.34), shortage of trained supervisors ( =3.20), poor infrastructural facilities (=3.23), and weak policy support (= 3.16). The study concludes that while Community Health Residency Programmes play a vital role in strengthening PHC service delivery, their full potential is limited by systemic and institutional challenges. It recommends improved funding, strengthened supervision, infrastructure development, and stronger policy coordination to enhance integration and sustainability.
