California report: Even fewer bypass-surgery deaths

A state report says California hospitals are reducing the already slim risk of death from coronary artery bypass surgery. The report, which was based on more than 32,000 operations performed in 2005 and 2006, also rated all 284 bypass surgeons in California. This is the fourth in a series of state reports that have charted a general decline in bypass surgery mortality rates from 2.9% in 2003, the first year studied, to 2.2% in 2006, the most recent year under review.
