The Association between Medicare Advantage Market Penetration and Diabetes in the United States.

The objective of this study is to explore the extent to which managed care market penetration in the United States is associated with the presence of chronic disease. Diabetes was selected as the chronic disease of interest due to its increasing prevalence as well as the disease management protocols that can lessen disease complications. We hypothesized that greater managed care market penetration would be associated with (1) lower prevalence of diabetes and (2) lower prevalence of diabetes-related comorbidities (DRCs) among diabetics.

Chronic Disease Prevalence and Medicare Advantage Market Penetration: Findings From the Medical Expenditure Panel Survey.

By March 2015, 30% of all Medicare beneficiaries were enrolled in Medicare Advantage (MA) plans. Research to date has not explored the impacts of MA market penetration on individual or population health outcomes. The primary objective of this study is to examine the relationships between MA market penetration and the beneficiary's portfolio of cardiometabolic diagnoses.

The relationship between HAART use and employment for HIV-positive individuals: an empirical analysis and policy outlook.
