Summary
Gaining health insurance through Medicaid or Marketplaces significantly increased access to usual care and preventive services. Individuals who remained uninsured experienced fewer healthcare access improvements.
Area of Science:
- Health Services Research
- Public Health Policy
- Healthcare Access
Background:
- Lack of health insurance is a barrier to accessing healthcare services.
- The Affordable Care Act expanded insurance coverage through Medicaid and Health Insurance Marketplaces.
- Understanding the impact of insurance expansion on healthcare utilization is crucial.
Purpose of the Study:
- To examine the association between gaining health insurance and obtaining a usual source of care.
- To assess the impact of new health coverage on the utilization of preventive care services.
- To compare healthcare access for newly insured individuals versus those remaining uninsured.
Main Methods:
- Utilized longitudinal survey data from 2013 and 2014.
- Compared individuals who gained coverage (Medicaid/Marketplace) in 2014 with those who remained uninsured.
- Analyzed changes in usual source of care and preventive service receipt.
Main Results:
- Newly insured individuals were significantly more likely to establish a usual source of care.
- Receipt of preventive care services increased substantially among those gaining coverage.
- Individuals who remained uninsured showed limited improvements in healthcare access.
Conclusions:
- Medicaid and Marketplace coverage expansion improved access to primary and preventive care.
- Health insurance is a key determinant of healthcare utilization.
- Policy interventions aimed at increasing insurance coverage can enhance public health outcomes.
