| Abstract: | A study was made on the causes of unsatisfactory progress in immunization coverage in an area of Tamil Nadu, southern India. The findings led to the appointment of additional community health workers (CHW), improvement in supervision, the enhancement of accessibility to services through an increase in the number of peripheral clinics and the organizing of temporary clinics, and the concentration of effort on underprivileged groups. As a result, immunization coverage was more than doubled. The Community Health and Development Project, a primary health care program serving 68 villages since 1981 with a population of about 80,000 was the site of the study which was conducted by discussions with staff and various members of the community. Issues explored were nonacceptance or dropout reasons, and specific factors affecting immunization coverage. A special effort was made to obtain the views of staff working at the periphery, particularly CHWS. The service area was divided into 4 sectors and the CHWS, auxiliary nurse midwives, community health nurses and other development staff in each were brought together for discussions. Views were also solicited from mothers' clubs and youth groups and in meetings with village leaders. Issues raised were further considered by supervisory staff. Statistical studies and other studies were done to clarify doubtful issues and test hypotheses emerging from the discussion. Poor immunization coverage was linked to inadequate supervision of CHWs, scattered communities (village with houses clustered together had better acceptance rates), difficulty of access to health services (distance factors), and low economic and educational status. In light of the study findings, community health workers were increased from 42 in 1984 to 57 in 1987 to cover all the villages, with modifications in selection method to make the worker acceptable to all sections of the villages; abolishment of the auxiliary nurse midwife and addition of a new category, health aide, to link the CHW and the community health nurse, increase of peripheral clinics from 37 to 75 and holding of more temporary clinics, more efforts to reach all socioeconomic groups and increased health education through film shows, drama, and work with village groups. |
