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.

Factors associated with adoption of robotic surgical technology in US hospitals and relationship to radical prostatectomy procedure volume.
The authors aimed to identify the factors associated with hospitals' decisions to adopt robotic technology and the consequences of these decisions. They found that hospitals in areas where a higher proportion of other hospitals had already acquired a robot were more likely to acquire one, as were those with more than 300 beds and teaching hospitals. They also found a significant association between years with a robot and the change in the number of radical prostatectomies. They concluded that local area robot competition was associated with the rapid spread of robot technology in the United States.
