Human-centered Design and Communities of Practice to Improve Home-based Tuberculosis Contact Investigation in Uganda

In a previous randomized control trial, the investigators identified gaps in the implementation of tuberculosis (TB) contact investigation at multiple levels of the service delivery cascade. Drawing on prior experiences, the investigators have recently developed a novel strategy to enhance the implementation of routine contact investigation procedures. This user-centered implementation strategy was created through serial prototyping guided by human-centered design (HCD) and employs communities of practice (CoP) as an adjunctive adaptation and sustainment strategy. The investigators are now conducting a stepped-wedge, cluster-randomized implementation trial in 12 study sites in Uganda to determine if the resulting user-centered implementation strategy enhances the delivery of TB contact investigation and other implementation outcomes, and also improves health outcomes.
