The first year after cancer treatment ends is a critical time to establish survivorship care for young adult (YA) cancer survivors ages 26 to 39. Receipt of evidence-based survivorship care, including surveillance for cancer recurrence based on national guidelines, remain low among YA survivors. At the same time, YAs ages 26 to 39 have the highest rate of both uninsurance and underinsurance among adults in the United States. Our team's prior work demonstrated that YA cancer survivors report low understanding of their health insurance and the services it covers, which affects their ability to navigate care. Together, these issues can lead to significant access to care barriers and severe medical cost consequences for this population. This proposal addresses the urgent need to improve YA cancer survivors' health insurance literacy and decrease financial toxicity, thus improving their ability to receive recommended survivorship care. Guided by Andersen and Aday's Behavioral Model of Health Services Use, we developed and pilot-tested a 4-session virtual patient navigation intervention for YA cancer survivors that was adapted from a pilot program for childhood cancer survivors. Initial results support feasibility, acceptability, and preliminary efficacy of both of these pilot trials with YA survivors ages 26 to 39. We now propose a randomized controlled trial to test the efficacy of this program ("CHAT-S," Cancer Health insurAnce Tools with Survivors) to improve health insurance literacy, financial toxicity due to medical costs, and post-treatment surveillance for recurrence among YA cancer survivors ages 26 to 39 (up to age 45). We plan to randomize N=300 (N=200 intervention; N=100 usual care) YAs with breast, testicular, lymphoma, sarcoma, and colorectal cancer who have completed initial treatment within the past year from 14 locations in the University of Utah Healthcare (UUHC) and Intermountain Healthcare (IH) systems. UUHC and IH have many rural (20%) and Hispanic/Latinx (18%) YA cancer survivors; we will oversample these important subgroups. We will determine whether CHAT-S improves health insurance literacy and financial toxicity at 6-month follow-up (primary outcomes). Further, UUHC and IH have an integrated data infrastructure which allows us to capture electronic health records and claims data to investigate whether CHAT-S improves surveillance care for recurrence at 18-month follow-up (secondary outcome). We will explore moderators (e.g., rurality, ethnicity) of the intervention effects. Finally, to inform future dissemination, we will conduct a budget impact analysis and a short-term and long-term time horizon cost-effectiveness analysis of CHAT-S. This proposal addresses the National Cancer Institute's goal of improving the care of cancer survivors and mitigating financial toxicity. We will demonstrate that a virtual health insurance literacy intervention can improve insurance literacy, financial toxicity, and surveillance care among YA cancer survivors, and provide guidance to improving survivorship care across the United States.
