Prior to the Choice Act Elderly Medicare-Enrolled Veterans Increased their Use of VA Healthcare versus Medicare
BACKGROUND:
In an era of increasing community care options, understanding how Medicare-enrolled Veterans choose between VA and Medicare can help policy-makers predict expected use of VA and non-VA care. No research has assessed system-level changes in VA reliance on outpatient care among Medicare-enrolled Veterans over an extended period and across an extensive array of outpatient service types. Thus, this study examined long-term trends in reliance on VA outpatient care at the system level among elderly Medicare-enrolled Veterans from FY2003 to FY2014. Using VA and Medicare data, investigators examined four visit types (primary care, mental health, specialty care, and surgery) and seven high-volume medical subspecialties (cardiology, ophthalmology, critical care/pulmonology, nephrology, dermatology, gastroenterology, and hematology oncology).
FINDINGS:
- The number of elderly Veterans enrolled in VA and Fee-for-Service (FFS) Medicare was 1.7 million in 2003, decreasing to 1.5 million in 2014.
- Medicare-enrolled Veterans, who had a choice of using VA or Medicare providers, steadily increased their reliance on VA outpatient services (all categories) prior to the Choice Act.
- Elderly Medicare-enrolled Veterans received most of their mental healthcare from VA (75% in 2003 to 77% in 2014), while receiving most of their primary care (76% in 2003, 65% in 2014), specialty care (86% in 2003, 78% in 2014), and surgical care (85% in 2003, 78% in 2014) through Medicare.
- The increase in VA reliance was driven by a decrease in Medicare-only users, and an increase in VA-only users. Among users during the study period, the proportion of VA-only users increased in primary care (28% to 40%), mental health (80% to 88%), specialty care (18% to 26%), and surgical care (18% to 28%). Similar trends were seen in seven high-volume medical subspecialties.
IMPLICATIONS:
- Despite the recent controversies of access to VA care, elderly Medicare-enrolled Veterans were increasingly reliant on VA outpatient care across a diverse range of services at the life stage of growing healthcare needs. This may reflect their greater satisfaction with VA care.
- Future research should explore the reasons for the increase in VA reliance to help VA inform policy planning around the provision of outpatient services, including the decision to expand internal VA capacity versus non-VA community care programs.
LIMITATIONS:
- This study did not include Veterans younger than age 65 who used Medicare due to disability.
