The Human-Centered Design and Communities of Practice to Improve Delivery of Home-based Tuberculosis Contact Investigation in Uganda Study (HCD CoP Study) aims to improve the quality of contact investigation in Uganda. In a previous trial (mHealth trial), we identified gaps in the tuberculosis contact investigation cascade in terms of implementation. In this study, we will utilize two innovative methodologies to address some of these gaps: Human Centered Design (HCD) and Communities of Practice (CoP). 

In the first phase of this study, we will explore stakeholder preferences for how contact investigation can be best 


delivered with a particular focus on improving the patient experience. At the end of this phase, we will have a well-defined implementation strategy for household contact investigation. We have partnered with a team of HCD design experts from IDEO.org to refine the implementation strategy. As of November 2019, we have completed our initial rounds of stakeholder interviews with plans to prototype implementation strategies in January 2020. 

Upon the completion of the HCD process, we will conduct a large, randomized controlled trial to evaluate the effectiveness of the new implementation strategy as part of phase 2.
