A pilot intervention to improve health insurance literacy and financial toxicity among recently diagnosed adolescents and young adults with cancer.

218 Background: Adolescents and young adults (AYAs; ages 18-39) with cancer report worries about costs and feeling uninformed about their insurance, which may impair their ability to navigate the health care system, use their insurance, and manage costs. We conducted a pilot randomized controlled trial (RCT) to assess a virtually delivered health insurance navigation intervention (“CHAT”) to improve health insurance literacy (HIL) and knowledge, increase awareness of insurance protections in the Affordable Care Act (ACA), and reduce financial toxicity and stress. Methods: CHAT is a 4-session program delivered by a patient navigator. Session content included learning about insurance, navigating your plan, insurance-related laws, & managing care costs. Eligible participants had access to a wireless device, were within their first year of cancer diagnosis, and were treated at oncology sites from the University of Utah Healthcare and Intermountain Healthcare systems. We assessed feasibility and preliminary efficacy of CHAT compared to usual navigation care, including HIL (9 items on confidence using insurance), insurance knowledge (13 items on terms such as deductible & copay), ACA protections (8 items), Perceived Stress Scale (PSS; 4 items), and COmprehensive Score for financial Toxicity (COST; 11 items) using t-tests. Results: From November 2020 to January 2022, 86 AYAs enrolled (46.2% approached consented); 68.6% were female, 72.1% white, 18.6% Hispanic, 34.9% age 18-25, 65.1% age 26-39, 83.7% had private insurance, and 10.5% public. Mean baseline HIL scores were 22.6 (range = 9-33, SD = 5.5). At baseline, 65.1% of participants were unaware of the ACA provision allowing appeals for coverage denials. 64.4% of intervention participants completed all 4 sessions; 86.0% completed the 5-month follow-up survey with data collection ongoing (74/86). At follow-up, compared to usual navigation care, CHAT participants had improvements in HIL, knowledge of insurance, and knowledge of ACA provisions (Table). While PSS improved more for CHAT than usual care, COST did not differ. Conclusions: Results support the feasibility and preliminary efficacy of CHAT with related improvements in HIL and knowledge of the ACA. Clinical trial information: NCT04448678. [Table: see text]
