Determinants of Family Planning and Child Immunization Services Integration in Urban Areas of Nigeria: A Longitudinal Analysis

Abstract

Background: Unmet need for contraception is high in the postpartum period. Research has identified the role that integration of family planning into child immunization services can have in addressing this need. However, evidence about the effects of family planning and immunization integration has been inconsistent and more evidence is required to determine whether and how to invest in integration. This study applies continuous facility-level family planning and child immunization integration index scores to: (1) determine whether facility-level integration changes over time, (2) assess the impact of the Nigerian Urban Reproductive Health Initiative (NURHI) - a program that aimed to increase modern contraceptive use - on integration, and (3) identify determinants of integration across facilities in urban areas of Nigeria. Methods: Longitudinal data from health facilities in six urban areas of Nigeria are available from 400 facilities at baseline and 385 facilities at endline. Difference-in-differences models are used to assess the impact of NURHI on Provider Integration and Facility Integration Index scores, and to identify facility-level determinants of integration. The two outcome measures, Provider and Facility Integration Index scores, measure attributes that support integrated service delivery. The independent variables are (1) time period (2) whether the facility received the NURHI intervention, and (3) facility-level characteristics. Results: Our results show that the Provider Integration Index scores increased significantly only among non-intervention facilities while Facility Integration Index scores did not increase significantly in either group. We find that NURHI did not have a significant effect on integration index scores. Results also pinpoint facility characteristics that influence integration, including public ownership and the proportion of providers who have received family planning training. Conclusion: Programs aiming to increase integration of family planning and immunization services should monitor and provide targeted support for the implementation of a well-defined integration strategy that considers the influence of facility characteristics and concurrent initiatives.
