Abstract: OBJECTIVE: To examine whether hospitals where patients obtain care explain racial/ethnic differences in treatment delay. DATA SOURCE: Surveillance, Epidemiology, and End Results data linked with Medicare claims. STUDY DESIGN: We examined delays in adjuvant chemotherapy or radiation for women diagnosed with stage I-III breast cancer during 1992-2007. We used multivariable logistic regression to assess the probability of delay by race/ethnicity and included hospital fixed effects to assess whether hospitals explained disparities. PRINCIPAL FINDINGS: Among 54,592 women, black (11.9 percent) and Hispanic (9.9 percent) women had more delays than whites (7.8 percent, p < .0001). After adjustment, black (vs. white) women had higher odds of delay (odds ratio = 1.25, 95 percent confidence interval = 1.10-1.42), attenuated somewhat by including hospital fixed effects (OR = 1.17, 95 percent CI = 1.02-1.33). CONCLUSIONS: Hospitals are the important contributors to racial disparities in treatment delay.
