Association of co-morbidities with financial hardship in survivors of adult cancer

Purpose To evaluate the impact of co-morbidities on financial hardship in adult cancer survivors and the role of health insurance and a usual source of care (i.e., a particular doctor's office/health center/other place that the person usually goes if he/she is sick or needs advice) in relieving this impact. Methods Using the Medical Expenditure Panel Survey, we estimated prevalence of two financial hardships, out-of-pocket (OOP) burden and financial worry, among 1196 adult cancer survivors. A modified Charlson co-morbidity index (CCI) assessed co-morbidities, which represent a medical event (e.g., a doctor's appointment) associated with co-morbid conditions within the past 1 year. Multivariable logistic regression tested the influence of health insurance and a usual source of care on associations of co-morbidities with financial hardship by middle/high vs. low-income families and by working vs. retirement-age individuals. Results Years since cancer diagnosis ranged from 0 to 76 years (mean: 10.3, SD: 9.8), 10 and 25% of survivors experienced OOP burden and financial worry. For OOP burden, increased CCI was a risk factor among survivors of low-income families, ORs: 1.91 (95% CI: 1.06, 3.46) for a CCI 1-2 and 3.37 (95% CI: 1.72, 6.61) for a CCI >= 3 vs. CCI of 0. For financial worry, increased CCI was a risk factor among working-age survivors, ORs: 1.58 (95% CI: 1.02, 2.47) for a CCI 1-2 and 2.15 (95% CI: 1.19, 3.87) for a CCI >= 3 vs. CCI of 0. However, having health insurance and a usual source of care did not mitigate impact of co-morbidities on financial hardship (P values > 0.05). Conclusions Impact of co-morbidities on OOP and financial worry burden was greatest in survivors of low-income families and working-age, respectively. Health insurance and a usual source of care did not relieve the impact of co-morbidities on financial hardship. Implications Effective strategies are warranted to mitigate financial hardship for survivors.

Automated summary

The study evaluated the impact of co-morbidities on financial hardship in adult cancer survivors and found that financial worry was more pronounced among survivors from low-income families, while survivors of working age were more likely to face out-of-pocket burden. Health insurance and a usual source of care did not alleviate the impact of co-morbidities on financial hardship.
