Financial toxicity of cancer treatment at a diverse county hospital.

Abstract

76 Background: The rising costs of cancer care increasingly results in financial distress for patients and their families. Low-income patients face a greater burden of financial toxicity, but few studies have characterized what factors contribute to this, and what interventions can relieve toxicity. Methods: From October 2017 to December 2017, we used a validated COST survey tool to understand the extent of financial burden that patients with cancer experience. We surveyed patients who receive their oncology care in a medical system that serves predominantly minority and low-income patients in Santa Clara County. We collected demographic information including sex, education level, ethnicity, income, insurance status, monthly out of pocket costs (OOPC) and employment status prior to diagnosis. We used a multivariable linear regression to study the association between the patient factors and financial burden as demonstrated by the COST score. All data were analyzed using Stata 14. Results: Demographic information is presented in Table 1. A total of 152 patients completed all 11 items of the COST survey. In the multivariate model, there was no significant difference in COST score by sex, education level, or ethnicity. However, income ≤$25,000 was associated with higher COST scores (p = 0.019), as was higher monthly OOPC (p = 0.003). Medicare patients and patients who were employed prior to diagnosis tended to have higher COST scores although not quite statistically significant (p = 0.057, p = 0.083). Conclusions: Patient-reported financial toxicity is an unmet concern among patients in this single institution study with a high proportion of underinsured patients. Higher OOPC and low income was associated with a higher financial burden. These findings suggest that patients would benefit from targeted interventions to mediate out of pocket costs of cancer care.[Table: see text]
