Veterans' care preference for coronary artery bypass grafting in a rural setting

We wanted to determine what factors were associated with rural veterans' use of Department of Veterans Affairs (VA) facilities over the private sector for coronary artery bypass grafting (CABG) surgery. We reviewed the charts of 137 veterans who were referred for CABG by their VA cardiologists. Most veterans (69%) obtained CABG through the VA system. Although patients who had to drive fewer additional miles to obtain VA care were somewhat more likely to use the VA system, patients who lacked insurance or faced high out-of-pocket cost estimates for care in the private sector obtained care through the VA at dramatically higher rates. Although patients using the VA system were younger and more likely to have significant coronary artery disease, clinical outcomes did not significantly differ across systems of care. As the VA begins to understand veterans' use of multiple systems of care, it will be important to understand what influences veterans' choice of VA or private sector care.
