Abstract
BACKGROUND: Childhood cancer survivors often face high healthcare costs to monitor and manage new or lasting effects of their treatment. Enhancing survivors' health insurance literacy (HIL) - the knowledge, ability, and confidence in enrolling in and navigating health plans - is vital for minimizing financial burden. Few studies have assessed the effect of a health insurance navigation program on improving HIL among survivors. We present the protocol for an ongoing randomized controlled trial (RCT) assessing the effectiveness of two health insurance navigation programs (HINT-S and HINT-A) on improving HIL, financial burden, out-of-pocket costs, and healthcare utilization for adult survivors of childhood cancer. METHODS: This three-arm RCT assesses the effectiveness of two digitally delivered health insurance navigation interventions and enhanced usual care (EUC) on improving HIL at six and 12 months in a national cohort of childhood cancer survivors. While HINT-S is composed of five synchronous, navigator-led sessions, HINT-A is an asynchronous, prerecorded set of five videos. EUC participants receive only a health insurance informational booklet. Financial burden, medical out-of-pocket costs, and healthcare utilization (receipt of preventive care, recommended screenings/vaccinations, and acute care) are assessed at 12 months. Moderators to the interventions' effectiveness will be investigated, as well as implementation outcomes (feasibility, acceptability, appropriateness, fidelity, and cost-effectiveness). CONCLUSIONS: There is a strong need for interventions to improve cancer survivors' HIL, helping them navigate the complexity of the U.S. healthcare system. This trial will elucidate the potential effectiveness and implementation of health insurance navigation programs that may benefit many cancer survivors. TRIAL REGISTRATION: NCT05527392.
