Abstract
BACKGROUND: Cardiovascular mortality has worsened among rural adults compared with urban counterparts over recent decades. Medicare Advantage (MA) enrollment is increasing in rural areas, yet its impact on access and affordability for high-risk cardiovascular populations remains unclear. This study evaluated differences in health care access, preventive care, and affordability barriers between rural adults with cardiometabolic conditions enrolled in MA versus traditional Medicare.
METHODS: A cross-sectional analysis was performed using 2021 to 2022 Medicare Current Beneficiary Survey data. Multivariable logistic regression was used to estimate adjusted risk differences (aRD) in access, preventive care, and affordability barriers between rural MA and traditional Medicare enrollees, adjusting for sociodemographic characteristics.
RESULTS: The study included 4274 rural beneficiaries with cardiometabolic conditions (weighted population 16 352 800, 53% women). Compared with traditional Medicare, MA enrollees were significantly less likely to miss an annual wellness visit (40.1% versus 50.1%; aRD, -13.4% [95% CI, -17.0% to -9.8%]) or face barriers to preventive care, such as not having annual cholesterol checks (aRD, -3.2% [95% CI, -5.2% to -1.2%]) and influenza vaccinations (aRD, -4.3% [95% CI, -7.8% to -0.7%]). However, MA beneficiaries were more likely to have problems paying medical bills (12.2% versus 6.9%; aRD, 2.5% [95% CI, 0.4%-4.6%]).
CONCLUSIONS: Rural MA beneficiaries with cardiometabolic conditions experienced fewer barriers to preventive care but reported greater difficulty paying medical bills than those in traditional Medicare. As MA expands in rural America, policies are needed to address affordability challenges while preserving access to preventive services.
