Financial toxicity among patients with lung cancer in a publicly funded health care system.

192Background: Financial distress has been established as a clinically relevant patient-reported outcome (PRO) associated with worse mortality and quality of life, but remains under-recognized by health care providers. Our goal was to define factors associated with financial toxicity (FT) in a public healthcare system. Methods: Patients with advanced lung cancer were recruited from outpatient clinics at the Princess Margaret Cancer Centre (Toronto, Canada). FT was measured with the validated Comprehensive Score for Financial Toxicity (COST) instrument, a 12-item survey scored from 0-44 with lower scores reflecting worse financial well-being. Data on patient and treatment characteristics, total out-of-pocket costs (OOP) and extended insurance coverage (EIC) were collected. Multivariable logistic regression models were fit for COST score and each variable, to determine factors associated with greater FT (COST < 21). Results: Of 251 patients approached, 200 (80%) participated. Median age of the cohort was 65...
