Brief Summary

Elevation in low density lipoprotein (LDL) cholesterol (LDL-C) is a causal risk factor for atherosclerotic established cardiovascular disease (ASCVD). Reduction of LDL-C with statins has been clearly demonstrated as a robust and cost-effective way of reducing the burden of ASCVD in individuals at risk. ASCVD is the leading cause of death and disability in Brazil and therefore prevention guidelines recommend LDL-C reduction with the aim of reducing disease burden in individuals at risk. Studies have shown a clear hiatus on awareness and treatment of cholesterol in Brazil. Thus, it became imperative to develop knowledge translation projects aiming at bridging the gap between science and clinical practice and ultimately leading to better outcomes. Cluster randomized clinical trials are the highest quality type of clinical research to test educational and active interventions aimed at changing behaviors or clinical practices. Therefore, this study is a pragmatic cluster randomized trial to assess the effect of a digitally enabled quality improvement intervention on LDL-C control in atherosclerotic established cardiovascular disease (ASCVD) patients.

Detailed Description

Elevation in low density lipoprotein (LDL) cholesterol (LDL-C) is a causal risk factor for atherosclerotic established cardiovascular disease (ASCVD). Reduction of LDL-C with statins has been clearly demonstrated as a robust and cost-effective way of reducing the burden of ASCVD in individuals at risk. ASCVD is the leading cause of death and disability in Brazil and therefore prevention guidelines recommend LDL-C reduction with the aim of reducing disease burden in individuals at risk. Studies have shown a clear hiatus on awareness and treatment of cholesterol in Brazil. Thus, it became imperative to develop knowledge translation projects aiming at bridging the gap between science and clinical practice and ultimately leading to better outcomes. Cluster randomized clinical trials are the highest quality type of clinical research to test educational and active interventions aimed at changing behaviors or clinical practices.To our knowledge, data from this study will be crucial to leverage LDL-C treatment in Brazil, considering efforts to improve population health. The present study represents one of the first trials testing a quality improvement (QI) intervention targeted to LDL-C reduction in ASCVD patients conducted in a middle-income country. These results will address whether the proposed QI intervention is feasible and effective in these settings. Therefore, this study is a pragmatic cluster randomized trial to assess the effect of a digitally enabled QI intervention on LDL-C control in ASCVD patients. This study will have 2 phases. Phase 1 will be an observational phase prior to randomization of clusters with the objective to assess the baseline LDL-C levels achieved for target patients. Phase 2 will be an interventional phase, in which clusters will be randomized to the digitally enabled quality improvement intervention or usual care, with the objective to assess the effect of a digitally enabled QI intervention on control of LDL-C levels in ASCVD patients.
