Integration of Systematic Screening For Tuberculosis in Outpatient Departments of Urban Primary Health-Care Facilities in Zambia: A Case Study of Kitwe District

Background: Tuberculosis (TB) is the leading cause of death from a single infectious agent globally, yet 3 million cases are missed every year. The World Health Organization recommends systematic screening of suspected active TB patients among those visiting the healthcare facilities. While many countries have scaled-up systematic screening of TB, there has been limited assessment of the extent of its integration into the health system. This study sought to explore factors that shaped the integration of systematic screening of TB in outpatient departments of primary healthcare facilities in Kitwe district, Zambia. Methods: This was a qualitative case study with health providers including district managers, TB focal point persons and laboratory personnel working in six purposively selected primary healthcare facilities. Data was collected through key informant (n=8) and in-depth (n=15) interviews. Data analysis was conducted using QDA Miner software and guided by Atun’s Integration framework.Results: Integration was facilitated by perceptions of the magnitude of the TB burden, alignment of the intervention with national TB aspirations, knowledge of stakeholder interests, power and values, regular performance management and intra-facility collaboration. Constraining factors included external partners’ influence in the TB screening program, unbalanced incentivization mechanisms, donor-driven financing and social determinants of health such as gender and stigma including the COVID-19 pandemic.Conclusion: Systematic screening of TB is not well integrated into the primary healthcare facilities to capture all those suspected with active TB that make contact with the health system. Finding the missing TB cases will, therefore, require contextual adaptation of the systematic screening for TB and strengthening the health system.
