Decline in the nationwide in-hospital mortality of patients undergoing coronary bypass surgery in the United States




Background


Significant advances in surgical techniques and postsurgical care have been made in the last 10 years. The goal of this study was to evaluate any decline in the age-adjusted in-hospital mortality rate of patients undergoing coronary artery bypass grafting (CABG) using a very large database from 1989 to 2004 in the United States.




Method


Using the Nationwide Inpatient Sample (NIS) database, we obtained specific ICD-9-CM codes for CABG to compile the data. In order to exclude the nonatherosclerotic cause of coronary disease, we used patients over the age of 40 years. We calculated total and age-adjusted mortality rate per 100,000 for this period.
