Regional Practice Patterns and Racial/Ethnic Differences in Intensity of End-of-Life Care

Abstract

Objective: To examine whether regional practice patterns impact racial/ethnic differences in intensity of end-of-life care for cancer decedents. Data Sources: The linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Study Design: We classified hospital referral regions (HRRs) based on mean 6-month end-of-life care expenditures, which represented regional practice patterns. Using hierarchical generalized linear models, we examined racial/ethnic differences in the intensity of end-of-life care across levels of HRR expenditures. Principal Findings: There was greater variation in intensity of end-of-life care among Hispanics, Asians, and whites in high-expenditure HRRs than in low-expenditure HRRs. Conclusions: Local practice patterns may influence racial/ethnic differences in end-of-life care.
