Association between hospital competition and quality of prostate cancer care.
The purpose of this retrospective study was to explore the relationship between hospital competition and outcomes in elderly with localized prostate cancer (PCa). The researchers also evaluated whether race moderated the relationship. The researchers applied the Hirschman-Herfindahl index (HHI) to measure hospital competition. The study outcomes were emergency room (ER) visits, hospitalizations, Medicare expenditure and mortality assessed in acute survivorship phase (two years post-PCa diagnosis), and long-term mortality. The study found that among 253,176 patients, percent change in incident rate of ER visit was 17% higher for one unit increase in HHI. Incident rate of ER was 24% higher for whites and 48% higher for African Americans. For one unit increase in HHI, hazard of short-term all-cause mortality was 7% higher for whites and 11% lower for African Americans. The hazard of long-term all-cause mortality was 10% higher for whites and 13% higher for African Americans.

Assessing the quality of surgical care for clinically localized prostate cancer: results from the CEASAR study.
Prior studies suggest that nationally endorsed quality measures for prostate cancer care are not linked closely with outcomes. Using a prospective, population based cohort the investigators measured clinically relevant variation in structure, process and outcome measures in men undergoing radical prostatectomy. The authors did not identify and meaningful variation in quality of care across racial groups, age groups and surgeon volume strata, in this cohort, suggesting that men were receiving comparable quality of care across these strata.
