 The purpose of this study is to evaluate approximately eight different R18 grants that will test practice change interventions to improve cardiovascular disease CVD prevention screening. The investigators will collect and analyze quantitative data context, process, and outcomes to identify the most effective combinations of intervention strategies for various practice types in relation to practice structure, context, and organizational characteristics associated with change in outcomes. The investigators will collect qualitative data observation, interviews, online diaries from grantees and selected practices to understand why and how those combinations are effective. The investigators will also gather documents and de-identified quantitative data from grantees.
