Understanding PrEP and Its Effectiveness
Preexposure prophylaxis (PrEP) represents a groundbreaking advancement in HIV prevention, offering nearly complete protection when used correctly. Clinical studies demonstrate that PrEP reduces the risk of contracting HIV by approximately 99% when taken as prescribed, making it one of the most effective preventive interventions available in modern medicine.
This pharmaceutical breakthrough has transformed the landscape of HIV prevention, providing at-risk individuals with a powerful tool to protect themselves. However, despite its proven efficacy, access to PrEP remains uneven across different populations, with economic factors playing a significant role in determining who can benefit from this life-saving medication.

The Role of Medicaid Expansion in Healthcare Access
Medicaid expansion has emerged as a critical policy mechanism for improving healthcare access among low-income populations. Following the implementation of the Affordable Care Act, states that chose to expand Medicaid coverage created new pathways for vulnerable individuals to access preventive healthcare services, including PrEP.
Breaking Down Economic Barriers
For many low-income individuals, the cost of PrEP and associated medical monitoring represented an insurmountable financial obstacle. Medicaid expansion addressed this barrier by providing comprehensive coverage that includes both the medication and necessary clinical services. This policy intervention created opportunities for populations previously unable to afford HIV prevention medications to access this critical resource.

Research Findings and Data Analysis
A comprehensive study published in Health Affairs in November provides compelling evidence for the effectiveness of Medicaid expansion in increasing PrEP access. Led by Elizabeth Stone, Ph.D., MSPH, from the Rutgers Center for Health Services Research at the Institute for Health, Health Care Policy and Aging Research, the research team conducted an extensive analysis spanning over a decade.
Nationwide Data Collection
Stone and her colleagues analyzed PrEP prescription data across all 50 states between 2012 and 2023, creating one of the most comprehensive datasets examining the relationship between Medicaid expansion and HIV prevention access. This methodological approach allowed researchers to identify patterns and trends that emerged as states implemented expansion policies at different times.
Initial Impact Measurements
The research revealed significant findings regarding immediate policy effects. “In the first year after a state expanded Medicaid, [approximately] one new person was getting PrEP relative to a new HIV diagnosis,” Stone explained in a recent video interview with Managed Healthcare Executive. This initial ratio demonstrated the immediate impact of expanding coverage, showing that policy changes could quickly translate into improved access to preventive care.

Long-Term Impact of Policy Implementation
The study’s most striking findings emerged when examining long-term trends following Medicaid expansion. Stone and her team observed prescription rates up to nine years after expansion implementation, revealing a progressive increase in PrEP utilization over time.
Accelerating Access Over Time
“The longer states had Medicaid expansion in place, the more they saw PrEP prescriptions ramp up,” Stone noted. This finding suggests that policy implementation effects compound over time, as awareness increases, healthcare systems adapt, and barriers gradually diminish.
Dramatic Improvement in Early-Adopting States
States that expanded Medicaid in 2014 experienced particularly impressive results. “For the first states that expanded Medicaid in 2014, right at the beginning, it was closer to 15 people who were getting PrEP for each new HIV diagnosis,” Stone reported. This fifteen-fold increase from the first-year baseline demonstrates the substantial public health impact achievable through sustained policy implementation.

Addressing Persistent Barriers to Access
Despite the clear benefits of Medicaid expansion, significant obstacles continue to limit PrEP access for many populations. The study identified racial, gender, and structural barriers that persist even in states with expanded coverage.
Systemic Challenges
These barriers include healthcare provider awareness and training gaps, stigma associated with HIV prevention, geographic limitations in healthcare access, and administrative complexities in navigating insurance systems. Addressing these multifaceted challenges requires comprehensive strategies that extend beyond insurance coverage expansion alone.

Future Implications for Public Health Policy
The research provides valuable evidence for policymakers considering healthcare expansion initiatives. The data demonstrates that Medicaid expansion functions as an effective tool for increasing access to critical preventive medications, with benefits that amplify over time.
Recommendations for Policy Implementation
States that have not yet expanded Medicaid should consider the compelling evidence demonstrating improved health outcomes and increased preventive care access. Additionally, states with existing expansion programs should focus on addressing persistent barriers through targeted interventions, provider education, and community outreach initiatives to maximize the policy’s potential impact on HIV prevention.
