CABG Post-operative Stroke
California also is the only state in the nation to report on rates of post-operative stroke in CABG, a known rate of complication. And this report represents the third year of data in this category.
Of the 27,217 patients who underwent CABG surgery in 2008 and 2009 (for this category two years were combined), 1.41% experienced a post-operative stroke. There was wide variation among hospitals in this category as well, ranging from 0% to 8.87%.
In this category, Alta Bates Summit Medical Center in Oakland, St. Bernardine Medical Center in San Bernardino and St. Joseph's Medical Center of Stockton had better performance ratings. For Alta Bates, this is the third year it has performed statistically better than the state average.
But Bakersfield Memorial Hospital, Good Samaritan Hospital of San Jose, Providence Tarzana Medical Center, and Scripps Memorial Hospital in La Jolla had worse performance in stroke rates after heart bypass surgery.
CABG Use of Mammary Artery as Graft
California is the only state in the nation to report the use of the mammary artery instead of the leg vein in the re-grafting procedure. According to the report, " Evidence shows that the IMA, when grafted to a coronary artery, is less susceptible to obstruction over time and remains fully open longer than vein grafts."
The state found no hospitals used the IMA frequently enough to rate a higher performance rate. Five hospitals were listed has having low IMA usage rate.
