Abstract
Background Maternal and Child Health (MCH) is global priority. Access and utilization of facility MCH services remain challenges in low and middle-income countries (LMICs). Evidence on barriers to providing and accessing services omits information on role of security within facilities. This paper explores the role of security in provision and use of MCH services in primary healthcare (PHC) facilities in Nigeria. Methods Study was carried out in Anambra state, Nigeria. Qualitative data was collected from 35 in-depth interviews (IDIs) and 16 focus group discussions (FGDs) with purposively identified key informants. Information gathered was used to build a program theory that was tested with another round of IDIs and FGDs and the literature. Data analysis and reporting were based on the Context-Mechanism-Outcome heuristic of Realist Evaluation methodology.Results Security elements (presence or lack of security guards, fencing, lighting and staff accommodation) facilitated or constrained provision and uptake of services respectively, by impacting behaviour of staff and patients. Security concerns of facility staff who did not feel safe to let in people into unguarded facilities, mirrored those of pregnant women who did not utilize health facilities because of fear of not being let in and attended to by facility staff.Conclusion Health facility security needs to be key consideration in program planning, to avert staff and women’s fear of crime which currently constrains provision and use of MCH care at health facilities. This, in turn, should contribute to improved MCH outcomes and facilitate achievement of Universal Health Coverage.
