Health‐related social needs, medical financial hardship, and mortality risk among cancer survivors

Abstract Background Cancer survivors may face challenges affording food, housing, and other living necessities, which are known as health‐related social needs (HRSNs). However, little is known about the associations of HRSNs and mortality risk among adult cancer survivors. Methods Adult cancer survivors were identified from the 2013–2018 National Health Interview Survey (NHIS) and linked with the NHIS Mortality File with vital status through December 31, 2019. HRSNs, measured by food insecurity, and nonmedical financial worries (e.g., housing costs), was categorized as severe, moderate, and minor/none. Medical financial hardship, including material, psychological, and behavioral domains, was categorized as 2‐3, 1, or 0 domains. Using age as the time scale, the associations of HRSNs and medical financial hardship and mortality risk were assessed with weighted adjusted Cox proportional hazards models. Results Among cancer survivors 18–64 years old ( n = 5855), 25.5% and 18.3% reported moderate and severe levels of HRSNs, respectively; among survivors 65–79 years old ( n = 5918), 15.6% and 6.6% reported moderate and severe levels of HRSNs, respectively. Among cancer survivors 18–64 years old, severe HRSNs was associated with increased mortality risk (hazards ratio [HR], 2.00; 95% confidence interval [CI], 1.36–2.93, p < .001; reference = minor/none) in adjusted analyses. Among cancer survivors 65–79 years old, 2‐3 domains of medical financial hardship was associated with increased mortality risk (HR, 1.58; 95% CI, 1.13–2.20, p = .007; reference = 0 domain). Conclusions HSRNs and financial hardship are associated with increased mortality risk among cancer survivors; comprehensive assessment of HRSN and financial hardship connecting patients with relevant services can inform efforts to mitigate adverse consequences of cancer.
