Abstract:
Currently, the US Department of Veterans Affairs provides medical care to more than four million veterans across the nation. Given the limited resources and increasing demand, the US Department of Veterans Affairs Health Administration (VA) is required by law to ensure that veterans with similar economic status and eligibility priority have similar access to VA health care, regardless of where they reside. This study, using descriptive statistics and logistic regression techniques, examines the factors that affect veterans' eligibility-status changes. This study found that veterans' demographics are correlated with the likelihood of eligibility-status conversion. More importantly, this study concludes that eligibility-status changes have a geographic pattern. These findings are important and useful in planning workload, as well as improving equal access of health care.
