Introduction: Cancer survivors increasingly report financial hardship as a consequence of the high cost of cancer care, yet the financial experience of traditionally underserved patients, including racial/ethnic minorities, non-English speakers, and rural residents, remains largely unstudied. The purpose of this study was to investigate potential disparities in the likelihood of financial hardship and nonadherence to surveillance colonoscopy.

Methods: In this cross-sectional study, individuals diagnosed with localized or regional colorectal cancer between 2004-2012 were ascertained by the population-based New Mexico Tumor Registry. Participants completed a mailed questionnaire or telephone survey about their cancer survivorship experience, including treatment-related financial hardship and receipt of surveillance colonoscopy. Participants were considered to have experienced treatment-related financial hardship if they reported any debt accumulation, bankruptcy filing, other financial sacrifices, or inability to pay medical bills as a consequence of their illness, its treatment, or its lasting effects. Multivariable logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI).

Results: In this sample of 277 colorectal cancer survivors, 44% of participants reported financial hardship. Individuals with low health literacy (OR 5.41, 95% CI 1.45-20.1), Spanish-speaking Hispanics (OR 3.09, 95% CI 1.39-6.87), divorced, separated or single survivors (OR 1.94, 95% CI 1.94, 95% CI 1.06-3.54), and rural residents (OR 1.86, 95% CI 1.06-3.28) were more likely to report financial hardship. Nonadherence to surveillance colonoscopy guidelines was two times as likely among participants reporting financial hardship (OR 2.17 95% CI 1.01-4.67) and among rural residents (OR 2.28, 95% CI 1.07-4.48) than those reporting no financial hardship and urban residents, respectively.

Conclusions: Substantial disparities in the likelihood of financial hardship and nonadherence to surveillance colonoscopy exist. Identifying patients at risk of financial hardship and developing interventions to reduce the financial burden of cancer may improve adherence to surveillance recommendations.
