Primary health care is the best approach to ensure access to equitable health care at a much lower cost. It contributes to substantial reduction in the need for secondary and tertiary care. More importantly, primary health care prepares the health system and health workers as firstline responders for future emergencies. In the past four years (2019-2022), Chhattisgarh state and the WHO Country Office for India have collaborated to conduct research for strengthening health systems in the state. This study covers the health workforce and its organization, mid-level health providers, health services in remote and rural areas, and demand-side assessments as a continuation of the technical assistance provided to the state.
