Abstract Background The Karamoja subregion in north-eastern Uganda has very high Tuberculosis (TB)case notification rates and, until recently, had suboptimal treatment completion rates among patients diagnosed with TB. We evaluated community knowledge, attitudes and practices towards Tuberculosis in order to identify barriers to TB control in this region. Methods From September to October 2022, we conducted a community-based survey in four districts in the Karamoja subregion. We collected data on TB knowledge, attitudes, and practices using a structured electronic questionnaire. We generated knowledge, attitude and practice scores. We used a survey-weighted zero-truncated modified Poisson model to assess the association between knowledge/attitude scores and respondents’ characteristics and a complementary log-log model to assess the association between practice scores and respondents’ characteristics. Data analysis was carried out using STATA version 14. Results A total of 1927 respondents were interviewed. Of these, 55.5% were female, and 1320 (68.6%) had no formal education. Overall, 68.5% 95% CI (59.6–76.7%) had knowledge scores of ≥ 60%. Higher TB knowledge scores were associated with being employed (adjusted prevalence ratio, aPR = 1.22, 95% CI 1.04–1.42, p = 0.01) while being a wife in a household was associated with lower TB knowledge (aPR = 0.90, 95% CI 0.82–0.99, p = 0.03). Being 25–34 years old was associated with a positive attitude towards TB (PR = 1.06, 1.01–1.11, p = 0.01). Over 85% of respondents would go to the health facility immediately if they had TB signs and symptoms. Almost all respondents (98.6%) would start TB treatment immediately if diagnosed with the disease. Conclusion More than two thirds of patients had good knowledge and practices towards TB which can be leveraged to improve uptake of TB control interventions in the region. Additional interventions to improve TB knowledge and practice should focus on specific segments within the communities e.g., older women in the households.

BACKGROUND: Tuberculosis(TB) is among the leading causes of infectious death worldwide. Contact investigation is an evidence-based, World Health Organisation-endorsed intervention for timely TB diagnosis, treatment, and prevention but has not been widely and effectively implemented. METHODS: We are conducting a stepped-wedge, cluster-randomised, hybrid Type III implementation-effectiveness trial comparing a user-centred to a standard strategy for implementing TB contact investigation in 12 healthcare facilities in Uganda. The user-centred strategy consists of several client-focused components including (1) a TB-education booklet, (2) a contact-identification algorithm, (3) an instructional sputum-collection video, and (4) a community-health-rider service to transport clients, CHWs, and sputum samples, along with several healthcare-worker-focused components, including (1) collaborative improvement meetings, (2) regular audit-and-feedback reports, and (3) a digital group-chat application designed to develop a community of practice. Sites will cross-over from the standard to the user-centred strategy in six, eight-week transition steps following a randomly determined site-pairing scheme and timeline. The primary implementation outcome is the proportion of symptomatic close contacts completing TB evaluation within 60 days of TB treatment initiation by the index person with TB. The primary clinical effectiveness outcomes are the proportion of contacts diagnosed with and initiating active TB disease treatment and the proportion initiating TB preventative therapy within 60 days. We will assess outcomes from routine source documents using intention-to-treat analyses. We will also conduct nested mixed-methods studies of implementation fidelity and context and perform cost-effectiveness and impact modelling. The Makerere School of Public Health IRB(#554), the Uganda National Council for Science and Technology(#HS1720ES), and the Yale Institutional Review Board(#2000023199) approved the study and waived informed consent for the main trial implementation-effectiveness outcomes. We will submit results for publication in peer-reviewed journals and disseminate findings to local policymakers and representatives of affected communities. DISCUSSION: This pragmatic, quasi-experimental implementation trial will inform efforts to find and prevent undiagnosed persons with TB in high-burden settings using contact investigation. It will also help assess the suitability of human-centred design and communities of practice for tailoring implementation strategies and sustaining evidence-based interventions in low-and-middle-income countries. TRIAL REGISTRATION: The trial was registered(ClinicalTrials.gov Identifier NCT05640648) on 16 November 2022, after the trial launch on 7 March 2022.
