Financial toxicity and its impact on health outcomes and caregiver burden among adult cancer survivors in the USA.

To examine the association between cancer-related financial toxicity on cancer survivors' physical and mental health outcomes and caregiver burden. 2016-2017 Medical Expenditure Panel Survey data were used to identify adult cancer survivors with cancer-related financial toxicity. Multivariable regression analyses were employed to examine the association between cancer-related financial toxicity and cancer survivors' self-reported physical and mental health outcomes and caregiver burden. A total of 53.7% of adult cancer survivors reported experiencing financial toxicity. Those who experienced financial toxicity reported 14% greater pain, and poorer physical and mental health outcomes as compared to those who did not experience financial toxicity, ranging from 38% greater odds for activity limitations to 427% greater odds for mental task limitation. Moreover, cancer survivors with financial toxicity reported 206% greater odds for caregiver burden. Intervention programs for reducing financial toxicity among adult cancer survivors and their caregivers should be developed.
