Assessing Health Care Utilization and Spending Among Older Medicare Beneficiaries With and Without HIV.

Improvements in treatment have made HIV a manageable chronic condition, leading to increased life expectancy and a growing share of people with HIV who are older. Older people with HIV have higher rates of many chronic conditions, yet little is known about differences in health care utilization and spending. This study compared health care utilization and spending for Medicare beneficiaries with and without HIV, accounting for differential mortality. The data included demographic characteristics and claims-based information. Estimated cumulative spending for beneficiaries with HIV aged 67 to 77 years was 26% higher for Medicare Part A and 39% higher for Medicare Part B compared with beneficiaries without HIV; most of these differences would be larger if not for greater mortality risk among people with HIV (and therefore fewer years to receive care). Future research should disentangle underlying causes for this increased need and describe potential responses by policymakers and health care providers.
