VHA enrollees' health care coverage and use of care.

The authors examined health care coverage for Veterans' Health Administration (VHA) enrollees and how their reliance on VHA care varies by coverage, using the largest and most detailed survey of veterans using VHA services ever conducted. The results showed that a majority of veterans who use VHA services have alternative health care coverage and that most of them use both VHA and non-VHA health care. The findings have important implications for quality of care and coordination of care.
