The use of video vignettes to measure health worker knowledge. Evidence from Burkina Faso.

The quality of care is a crucial determinant of good health outcomes, but is difficult to measure. Survey vignettes are a standard approach to measuring medical knowledge among health care providers. Given that written vignettes or knowledge tests may be too removed from clinical practice, particularly where "learning by doing" may be an important form of training, we developed a new type of provider vignette.
