Service provided by CHAG institutions cover the whole range of curative, preventive, promotive and rehabilitative services. Many of the mission hospitals in the rural areas providing primary level curative services also provide one or two specialized services such as eye care or specialist gynecological surgery for which clients would otherwise have had to travel long distances to bigger centers. Some of these hospitals have been designated centers of good practices by government and are sites for training health professionals.

The primary health care services include immunization, family planning, maternal and child health services and health education.
