Outcome Measures
Primary Outcomes: Survey
Health Insurance Literacy (Paez et al., 2014)	1. Understanding of terms (e.g., premium, deductible, co-payments, co-insurance, out-ofpocket spending limits, annual limits) 2. Confidence in choosing, comparing, and using insurance plans
Financial Toxicity (de Souza et al., 2014; de Souza et al., 2017)	Perceptions and behaviors regarding costs of cancer care
Secondary Outcomes: EHR/claims/facilities data
Surveillance Care for Recurrence	Determinations about the appropriateness of surveillance for each participant will follow National Comprehensive Cancer Network (NCCN) for each disease type. These guidelines incorporate factors such as cancer histology and stage. We will use procedure and diagnosis codes from the medical records, facilities data, and claims data to identify the types of care received.
Other Medical Care	Types of providers seen (oncologist, primary care, social workers, health educators, etc); Number of visits/types in the past year. We will use procedure and diagnosis codes from the medical records, facilities data, and claims data to identify the types of care received.
