Abstract

Objective: We analyzed the association between ethnicity and outcomes among prostate cancer patients across hospital and surgeon volume groups.

Methods: In this retrospective cohort study using SEER-Medicare databases for the period between 1995 and 2003, prostate cancer cases were identified and retrospectively followed for one year pre- and up to eight years post-diagnosis. Based on volume, hospitals and surgeons were divided into three groups each. For each group, we fitted separate models to analyze the association between ethnicity and outcomes such as complications, eight-year mortality and cost, adjusting for covariates. Poisson (zero inflation), generalized linear model (log-link), and Cox regression models were used.

Results: African American ethnicity was associated with 30-day complications among medium volume hospital group. African American patients receiving care at medium volume hospitals and from medium volume surgeons had higher costs. Hispanic patients receiving care at low and medium volume hospitals had lower cost compared to white patients. Hispanic patients receiving care from a high-volume surgeon experienced increased hazard of long-term mortality.

Conclusions: Association between ethnicity and outcomes varies across hospital and surgeon volume groups. Thus, volume based policy measures may need further exploration for understanding the interaction between structure, process, volume and outcomes.
