Impact of hospital volume on racial disparities in cardiovascular procedure mortality.

Black and Hispanic patients were more likely to receive cardiovascular procedures in low-volume hospitals, but hospital volume did not explain a large proportion of racial differences in post-procedure mortality. Additional research is needed to determine why black patients have increased mortality after cardiovascular procedures and how these mortality rates can be reduced.http://www.sciencedirect.com/science/article/pii/S073510970502570
