Introducing the SEER-Medicare-Housing and Urban Development data linkage: A novel resource for examining the association of housing assistance and cancer care and outcomes.

Abstract

200 Background: Lack of stable and affordable housing is an important social determinant of health. Federal housing assistance—through housing choice vouchers, public housing, and other programs—may buffer against housing vulnerabilities among low-income households, but research examining the association of housing assistance and cancer care has been limited. We introduce a new linkage of SEER-Medicare and Housing and Urban Development (HUD) administrative data that can be used to examine housing assistance and cancer care and patient outcomes to inform efforts to reduce inequities. Methods: Individuals enrolled in HUD programs 2006-2021 were linked with cancer diagnoses 2006-2019 identified in the SEER-Medicare data from 16 states using Match*Pro probabilistic linkage software. HUD administrative data include timing and type of housing assistance and verified household income. Medicare administrative data are available through 2020. We describe the cohort aged ≥66 years with continuous Medicare fee-for-service Parts A/B coverage surrounding diagnosis who had episodes of housing assistance: 1) at diagnosis or 2) starting within 3 years after diagnosis. Because supply of housing assistance is limited, eligible, low-income families are frequently wait-listed; individuals who receive housing assistance after diagnosis can serve as controls for individuals with housing assistance at diagnosis. Results: Among 42,197 individuals aged ≥66 years diagnosed with cancer and with housing assistance, the most common diagnoses were female breast (n=8,108), lung (n=5,400), colorectal (n=5,197), and prostate (4,548) cancers. Sociodemographic characteristics were similar among the 35,873 individuals with HUD assistance at diagnosis and 6,334 who received it later (Table). Both groups were majority female and non-Hispanic white and with median household income <$14,000. Private multifamily housing programs were the most common form of assistance, followed by housing choice vouchers, and public housing. Conclusions: This novel data linkage will be available through the National Cancer Institute and can be used to explore the ways in which housing assistance is associated with cancer diagnosis and outcomes, including the role of housing assistance in potentially reducing or contributing to inequities across racialized and ethnic groups.[Table: see text]
