The census-based, impact-oriented approach: Its effectiveness in promoting child health in Bolivia

Abstract

This paper describes the effectiveness for child health of a primary health care approach developed in Bolivia by Andean Rural Health Care and its colleagues, the census-based, impact-oriented (CBIO) approach. Here, we describe selected achievements, including child survival service coverage, mortality impact, and the level of resources required to attain these results. As a result of first identifying the entire programme population through visits at least biannually to all homes and then targeting selected high-impact services to those at highest risk of death, the mortality levels of children under five years of age in the established programme areas was one-third to one-half of mortality levels in comparison areas. Card-documented coverage for the complete series of all the standard six childhood immunizations among children 12-23 months of age was 78%, and card-documented coverage for three nutritional monitorings during the previous 12 months among the same group of children was 80%. Coverage rates in comparison areas for similar services was less than 21%. The local annual recurring cost of this approach was US $8.57 for each person (of all ages) in the programme population. This cost includes the provision of primary care services for all age groups as well as targeted child survival services. This cost is well within the affordable range for many, if not most, developing countries. Manpower costs for field staff in Bolivia are relatively high, so in countries with lower salary scales, the overall recurring cost could be substantially less. An Expert Review Panel reviewed the CBIO approach and found it to be worthy of replication, particularly if stronger community involvement and greater reliance on volunteer or minimally paid staff could be attained. The results of this approach are sufficiently promising to merit implementation and evaluation in other sites, including sites beyond Bolivia.
