1. Study identification
EU PAS Register NumberEUPAS4085
Official titleCost-Effectiveness Analysis of Treatment with Statins in Primary Prevention of Vascular Events.
Study title acronymEPREV project
Study typeObservational study
Brief description of the studyObjectives: 1. To Analyze the cost-effectiveness of statins treatment by different baseline cardiovascular risk strata. 2. To analyze the cost-effectiveness of statins therapy according to baseline cholesterol and total cholesterol reduction. 3. Set breakpoints based on the baseline cardiovascular risk, cholesterol and basal absolute reduction of cholesterol on the basis of the cost-effectiveness.
Subjects: People without a history of vascular events receiving treatment in any public Primary Care Centre (Institut CatalĂ de la Salut). Data will be obtained from the Information System for the Development of Primary Care Research (SIDIAP) whose primary source of data are electronic medical records (e-CAP) and other data sources, such as CATSALUT's invoice offices pharmacy and the Minimum Basic Data Set (CMBD).
Methodology: The design consists of two parts: firstly, from a matched cohort on the basis of propensity score, we will estimate the following parameters : 1. incidence density of cardio and cerebrovascular events, 2. population risk factors prevalence for baseline cardiovascular risk calculations, 3. Markov model utilities. The study will include approximately 83,500 new users of statins in the period of the study and a ratio of at least 3 controls per case (250,000 persons in the unexposed group). The follow-up period will be four years.
Subsequently, we will build a Markov model for cost-utility analysis from cohort data and data on costs from the perspective of the NHS. The analysis will be performed based on the ratio of incremental cost-effectiveness (ICER).
