With the targets of recognizing the importance of Health in the process of economic and social development and improving the quality of life of our citizens, the Government of India has resolved to launch the National Rural Health Mission to carry out necessary architectural correction in the basic health care delivery system. This District Health Action Plan (DHAP) is one of the key instruments to achieve NRHM goals. This plan is based on the changing healthcare requirements of the population of Samastipur district. This document has been prepared on the basis of a situation analysis. The teams engaged have made an anatomy of the coverage of poor women and children. The barriers and constraints in the service process have been identified. The focus has also been given on current availability of health care infrastructure in public/NGO/private sector, availability of wide range of providers. This DHAP has been evolved through a participatory and consultative process, wherein community and other stakeholders have participated and ascertained their specific health needs in villages, problems in accessing health services, especially poor women and children at local level. The goals of the Mission are to improve the availability of and access to quality health care by people, especially for the segments residing in rural areas e.g. The department of Health and Family Welfare and State Health Society of Bihar deserve appreciation for their dynamic leadership in managing health care sector reform programme.Which virtually may provide to us backup materials for replicating strategies.
