Improving Immunization Coverage in Rural Areas of Ecuador: A Cost-Effectiveness Analysis

Abstract

This study describes the costs and outcomes of two different immunization strategies used by the district level of the Ministry of Health carried out between 1993 and 1995 in Low-Napo area, Napo, Ecuador. One was centrally planned and managed by the District Hospital (DH) and the other planned and implemented together with community health workers (CHW). Immunization costs were estimated directly from survey records and communication of the Ministry of Health. Outcomes information was abstracted from the vaccination statistics of the Napo Province Health Department for 1993/1995. Community health workers strategy immunized 113 children with an average cost of US $32 per child. District Hospital strategy had an average cost of US $777.6 per immunized child.Thus, CHWs strategy is more effective and less costly than the DH strategy. This study shows that in order to maximize the cost-effectiveness of immunization, it is important to involve community participation in both planning and implementation. Continuous follow-up and evaluation of the immunization programme and further research on vaccine efficacy are necessary in order to maintain these results.
