Participants of the TREATS TB prevalence survey (TBPS) visited a mobile field site and were guided through a flow of stations (registration, TB-symptom screening, Chest X-ray, sputum collection point, HIV-testing). Those eligible for follow-up were visited at home were questionnaire was administered, then participants were referred to central location for CXR and sputum collection if eligible. All data collected at different stations within the TBPS and at different time points and locations at the follow-up was recorded using a tailor-made electronic Data Management System using a mySQL relational database in a local area network. Data from the mobile field site and from the different time points and locations was daily synchronized to a central location at Zambart. Electronic data capturing of questionnaires, administered by Research Enumerators through interviews were combined with results of HIV rapid test, bacteriological test for TB in sputum and chest Xray- CAD4TB results both from the TBPS and the follow-up.
