ObjectiveTo understand how treatment-related financial burden affects patients with gynecologic cancer and to identify targets for interventions to reduce financial toxicity.MethodsPatients with gynecologic cancer were invited to participate in a qualitative focus group study. Each participant completed an online, secure survey that included questions regarding diagnosis, treatment, employment status, and income. The Comprehensive Score for Financial Toxicity (COST) tool was used to measure economic burden (COST score 0–44), with lower scores indicating worse toxicity. Each participant then took part in a virtual semistructured focus group with a social worker and a study staff member. Three investigators independently analyzed the transcripts for common themes and reconciled disagreements through consensus.ResultsOver 60% of participants had private insurance, and 54% had moderate to high financial toxicity (COST scores <26). The five most commonly discussed themes included extent of insurance coverage, out-of-pocket health expenses, employment status changes, health system inefficiencies, and opportunity costs. Minor themes included issues surrounding delayed care, provider conversations, parking, and transportation. Participants with moderate to high toxicity reported strain associated with employment status changes, opportunity costs, and health system inefficiencies more often than those with mild toxicity.ConclusionsOur findings suggest that patient-centered interventions to optimize insurance coverage and enhance care coordination may reduce financial toxicity. Both targets are potentially immediately actionable and could have downstream effects on health outcomes. Meanwhile, advocacy efforts to improve work leave policies and reduce out-of-pocket health expenditure are system-level interventions that also should be considered to curtail financial toxicity.
