Vignettes are a valid tool for measuring the quality of clinical practice. They can be used for diverse clinical settings, diseases, physician types, and situations in which case-mix variation is a concern. They are inexpensive and easy to use. Vignettes are particularly useful for comparing quality among and within sites and may be useful for longitudinal evaluations of interventions intended to change clinical practice.

Although more research is needed to evaluate the cause of inaccuracies and the relative contributions of patient, provider, and system level effects, it appears that significant inaccuracies in administrative data are common. Interventions aimed at correcting these errors appear feasible.

Vignettes can measure and predict prevention performance. Vignettes may be a less costly way to assess prevention performance that also controls for patient case-mix.

Collaborative care models for depression in primary care are effective and cost-effective, but difficult to spread to new sites. Translating Initiatives for Depression into Effective Solutions (TIDES) is an initiative to promote evidence-based collaborative care in the U.S. Veterans Health Administration (VHA). Social marketing applies marketing techniques to promote positive behavior change. Described in this paper, TIDES used a social marketing approach to foster national spread of collaborative care models.TIDES social marketing approachThe approach relied on a sequential model of behavior change and explicit attention to audience segmentation. Segments included VHA national leadership, Veterans Integrated Service Network (VISN) regional leadership, facility managers, frontline providers, and veterans. TIDES communications, materials and messages targeted each segment, guided by an overall marketing plan.ResultsDepression collaborative care based on the TIDES model was adopted by VHA as part of the new Primary Care Mental Health Initiative and associated policies. It is currently in use in more than 50 primary care practices across the United States, and continues to spread, suggesting success for its social marketing-based dissemination strategy.Discussion and conclusionDevelopment, execution and evaluation of the TIDES marketing effort shows that social marketing is a promising approach for promoting implementation of evidence-based interventions in integrated healthcare systems.

When providers in 6 different countries were asked how they would care for the same patient, there was wide variation within and between countries. Nevertheless, 11% of the physicians scored over 80%, suggesting good quality of care is possible even with resource constraints. Use of validated clinical vignettes, which can be applied affordably at scale, could help improve quality of services in low- and middle-income countries.

Vignettes are a useful method for making cross-national comparisons of the quality of care provided in very different settings. The vignette measurements revealed that some physicians in Macedonia performed at a standard comparable to that of their counterparts in the United States, despite the disparity of the two health systems. We infer that in poorer countries, policy that promotes improvements in the quality of clinical practice-not just structural inputs-could lead to rapid improvements in health.
