This project is funded under the Robert Wood Johnson Foundation’s Research in Transforming Health and Health Care Systems (RTHS) program, which supports policy-relevant, community-engaged research on current or potential policies to transform health and health care systems. The goal of the study is to assess how state-level health insurance benefit mandates impact affordability and access to services for fertility preservation among pediatric, adolescent, and young adult Hispanic/Latino cancer patients in California. The study seeks to assess whether Hispanic/Latino cancer patients experience disparities in access to and affordability of fertility preservation services following implementation of the mandate; understand how the policy and its downstream implementation processes impact disparities; and identify best practices for implementation strategies. The research team plans to use a mixed methods approach, collecting data from newly diagnosed cancer patients about their experiences with insurance benefits and services for fertility preservation; the patient data will be integrated with data on implementation of the mandate collected from the state insurance regulator, a sample of insurance plans, and fertility clinics. The research team is comprised of a partnership between an academic institution, University of California San Diego, and a cancer navigation non-profit organization, Cancer Resource Center of the Desert. Deliverables will include a project work plan and annual and final narrative and financial reports, as well as a range of products to reach policymakers and other audiences for study findings.
