Study Arms:
- Standard Implementation Strategy Period (Type: ACTIVE_COMPARATOR): During the standard implementation strategy period, CHWs at all sites will receive the standard TB program training on TB contact investigation and supportive supervision from the on-site National TB Program focal person.
- Enhanced Contact Investigation Intervention Period (Type: EXPERIMENTAL): The enhanced contact investigation strategy includes 4 implementation facilitation tools and 3 continuous quality improvement techniques and will be delivered as a branded package named for an inspirational Luganda phrase that is translated as We are together with you. Implementation facilitation tools include 1) a TB education pamphlet, 2) a contact identification algorithm, 3) an instructional video on sputum collection, and 4) community health riders who transport clients, community health workers, and sputum samples by motorcycle. The continuous quality improvement techniques delivered as the community of practice package include 1) community of practice meetings, 2) audit and feedback reports and 3) a group chat application.
