Paid Sick Leave, Care Delays, and Mortality Risk in Working Cancer Survivors

PURPOSE – Cancer survivors endure costly and time-intensive care throughout treatment and survivorship. Paid sick leave provides employment and financial stability while supporting time off for medical needs. We investigated whether paid sick leave is associated with financial hardship and overall and cancer-specific mortality risk in working adult cancer survivors. METHODS – Working adults age 18-64 years with a cancer history were identified from the National Health Interview Survey (NHIS) between 2011 and 2023. Associations of paid sick leave and financial hardship (medical care delays, problems paying medical bills, worry about paying medical bills, and cost-related medication underuse) were examined with 2011-2018 and 2019-2023 data using separate multivariable logistic regressions because of survey redesign in 2019. Linked mortality files from the National Death Index were available for 2011-2018 respondents. The association of paid sick leave and mortality risk was examined with multivariable Cox proportional hazards models. RESULTS – A total of 8, 091 and 3, 919 working cancer survivors were identified from the 2011-2018 and 2019-2023 NHIS, respectively. Paid sick leave was associated with decreased medical care delays because of cost (2011-2018 odds ratio [OR], 0.74 [95% CI, 0.60 to 0.93]; P =.008; 2019-2023 OR, 0.51 [95% CI, 0.35 to 0.74]; P <.001) but not consistently with other forms of financial hardship. In adjusted analyses, paid sick leave was associated with significant reductions in risk of overall mortality (hazard ratio [HR], 0.74 [95% CI, 0.61 to 0.9]; P =.003) and cancer mortality (HR, 0.74 [95% CI, 0.61 to 0.91]; P =.003). CONCLUSION – In working cancer survivors, paid sick leave is associated with decreased care delays and lower overall and cancer-specific mortality risk, which may be due to maintained employment, household income, and health insurance coverage leading to improvements in treatment access, affordability, and overall survivorship care.
