QURE works with clients to design a prospectively designed study. If an intervention is included in the design, participants are randomized so that causality can be determined. The effect of the policy system level change are specified before hand and included in the CPV™ vignettes. CPV™ vignettes are given to providers and, like a typical clinical visit, take 10-15 minutes to finish. CPV™ vignettes are administered online at the providers convenience. Data collection is fast and accurate. Studies using CPV™ vignettes involve only 1-2 months to complete data collection and produce timely and detailed results, making them a highly favorable alternative to a traditional randomized prospective control trial.
