{Abstract}: <B>BACKGROUND: </B>Cardiovascular disease (CVD) is the primary cause of premature morbidity and mortality in the United States and Tennessee ranks among the highest in CVD events. While patient-centered outcomes research (PCOR) evidence-based approaches that reach beyond the traditional doctor-patient visit hold promise to improve CVD care and prevent serious complications, most primary care providers lack time, knowledge, and infrastructure to implement these proven approaches. Statewide primary care quality improvement (QI) collaboratives hold potential to help address primary care needs, however, little is known regarding their effectiveness in improving uptake of PCOR evidence-based population health approaches and improving CVD outcomes. This study describes the design and implementation of a stepped-wedge cluster randomized controlled trial to assess the effectiveness of participation in a statewide quality improvement cooperative (The Tennessee Heart Health Network [TN-HHN]) on cardiovascular outcomes.<BR><B>METHODS: </B>The TN-HHN Effectiveness Study randomized 77 practices to 4 waves (i.e., clusters), with each wave beginning three months after the start of the prior wave and lasting for 18 months. All practice clusters received one of three Network interventions, and outcomes are measured for each three months both in the control phase and the intervention phase. Primary outcomes include Center for Medicare and Medicaid Services measures for aspirin use, blood pressure control, cholesterol control, and smoking cessation (ABCS).<BR><B>CONCLUSIONS: </B>This trial, upon its conclusion, will allow us to assess the effect of participation in a statewide quality improvement cooperative on cardiovascular outcomes as well as key contributors to successful practice transformation.
