The U.S. Veterans Health Administration (VHA) provides comprehensive health care to veterans through VHA-run medical centers. Previously, some have been concerned that the quality of care in VHA centers might not be as high as in other settings. Since the early 1990s, the VHA has worked to improve the quality of the health care it delivers. An important part of that effort has been a program that measures health care quality and holds administrators of VHA medical centers responsible for maintaining high-quality care at their institutions. Recent studies suggest that, in the areas where the VHA measures quality, care in the VHA system is better than it is in other health systems. It is unknown whether quality is better in the many other areas for which the VHA does not follow quality measures.
