Regional Practice Patterns and Racial/Ethnic Differences in Intensity of EndofLife Care
Objective: To examine whether regional practice patterns impact racial/ethnic differences in intensity of endoflife 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 6month endoflife care expenditures, which represented regional practice patterns. Using hierarchical generalized linear models, we examined racial/ethnic differences in the intensity of endoflife care across levels of HRR expenditures.
Principal Findings: There was greater variation in intensity of endoflife care among Hispanics, Asians, and whites in highexpenditure HRRs than in lowexpenditure HRRs.
Conclusions: Local practice patterns may influence racial/ethnic differences in endoflife care.
