Financial toxicity among veterans with cancer

103 Background: Financial toxicity of cancer care has not previously been studied within the Veterans Health Administration (VHA). The VHA provides health care for veterans in VA hospitals across the United States (US). It is a single-payer system and the largest integrated health system in the US and in this study we sought to assess financial toxicity experienced by veterans at a VA hospital. Methods: We asked veterans with oncology clinic visits at the VA Palo Alto to complete a survey that included an 11-item validated questionnaire called the COST tool. The COST tool calculates a score 0-44 with higher scores suggestive of higher financial toxicity. We also assessed demographic factors including gender, education, race, income, and insurance status as well as monthly out of pocket costs (OOPC) and suggested resources to reduce burden. We coded responses and calculated descriptive statistics with proportions. Results: A total of 84 veterans completed the survey and demographic factors are depicted in Table. Veterans were predominantly male (96%), high school or less educated (46%), white (61%), with annual income less than $50,000 (81%), and VA insurance (95%). The mean COST score was 21. The majority of veterans (63%) reported less than $100 of monthly OOPC and many (56%) reported transportation as a major expense and requested transportation resources. Conclusions: Financial toxicity is an unmet concern among veterans. Despite low monthly OOPC in the VHA single-payer system, financial toxicity as measured by the COST score at a VA hospital was as high as a nearby academic center. Transportation was the most significant expense and future studies should evaluate interventions to reduce the financial burden of transportation for veterans. [Table: see text]
