Identifying enablers and barriers to the control of multidrug-resistant tuberculosis in Abia State, Nigeria: A qualitative study

Abstract

Drug-resistant tuberculosis (TB) is a significant public health threat in high-burden TB countries, including Nigeria, constraining the achievement of End TB targets. Nonetheless, Nigeria's health system factors shaping the care of patients with multidrug-resistant tuberculosis (MDR-TB) are understudied. The study assessed the enablers and barriers to implementing MDR-TB care and treatment in Abia State, Nigeria. This is a qualitative interview study adopting a phenomenological approach. We interviewed twelve participants comprising health workers and TB policymakers with roles in MDR-TB patient management at the national (n = 2) and state (n = 10) levels in May 2022. We used maximum variation sampling to purposively select participants based on their roles, availability, and consent. The data were analysed thematically. The factors enhancing care for patients with MDR-TB include using a certificate of readiness, community involvement, donor financing, availability of treatment centre, effective facility-community linkage, treatment support, multidisciplinary care team, training service providers, availability of oral drugs, expansion of diagnostic facilities, data tool availability, review meetings, and data-focused supervision. In contrast, the factors constraining MDR-TB management are poor implementation of infection control policy, donor dependence, delayed initiation of treatment, poorly motivated health workers, health worker stigma, shortage of personal protective equipment, and role conflict in data management. The findings highlight critical health systems strengths and weaknesses in MDR-TB control. MDR-TB care policies must build on the enablers and address the barriers to strengthen the care for patients with MDR-TB.
