Caribbean and South America Team-based Strategy to Control Hypertension

The CATCH Study includes a two-year UG3 Planning Phase and a four-year UH3 Implementation Phase. In the UH3 Implementation Phase, we will first conduct a cluster randomized implementation trial to test the effectiveness and implementation of a team-based care strategy to implement a single-pill combination strategy for hypertension control among patients with hypertension in 40 clinics from Colombia and Jamaica (20 in each country). Twenty clinics will be randomized to the team-based care intervention and 20 to provider training intervention. A total of 1,680 patients (42 per clinic) with uncontrolled hypertension will be recruited into the study and followed for 18 months for effectiveness and implementation outcomes. A post-intervention study visit will take place 6 months after the end of the 18-month intervention to evaluate the sustainability of the implementation strategies. We will subsequently conduct a pre- and post- scale-up comparison study to implement the team-based care strategy in all remaining public primary care clinics that provide chronic disease management in Jamaica and primary care clinics in the seven participating departments in Colombia. A pre- and post- scale-up comparison design will be used to assess barriers and implementation outcomes before and 12 months after the scale-up intervention at the clinic, primary care physician, nurse/pharmacist, and community health worker (CHW) levels.
