Clinical studies are used to determine the effectiveness—real world opportunities for new products, policies or delivery models and payment systems. Unfortunately, without controlling for patient variability, practice differences and the quality of the medical record determining practice change requires a large sample size, a long time horizon and trained nurse abstractors. A typical clinical study is beyond the means of most budgets costing millions of dollars and takes 2-3 years to complete.
CPV vignettes measure clinical practice, practically and accurately in a fraction of the time and costs. A typical QURE study takes 4-6 months, yields peer-review data and costs 85% less than a traditional randomized control study. CPV vignettes have been validated as measures of clinical practice in two large randomized control studies (see Publications).
