Hospital Volume & Mortality: Trends in High-Risk Surgery

A growing number of studies have reported inverse relationships between hospital volume and surgical mortality, with lower mortality seen in higher-volume institutions. There have been numerous efforts to concentrate selected operations at high-volume hospitals. The Leapfrog Group, a consortium of large corporations and public agencies that purchase healthcare for their employees, has been among the most prominent advocates of volume-based referrals. Private payers and professional organizations have also established minimum-volume standards as part of Centers of Excellence accreditation programs for a variety of operations. “Despite these efforts, little is known if they have altered referral patterns for high-risk surgery,” says Jonathan F. Finks, MD. Throughout the country, more and more surgical patients are being treated at high-volume hospitals, but the net effects on operative mortality can be difficult to predict. Dr. Finks says, “for example, hospital volume of a few high-risk cancer procedures, such as pancreatectomy, appears to be a strong predictor of operative risk. At the same time, relationships between surgical volume and outcome are much weaker for most operations.” “Some strategies that appear to be of particular benefit include use of operating-room checklists, outcomes measurement and feedback programs, and national and regional collaborative quality-improvement initiatives.” In a study published in the June 2, 2011 New England Journal of Medicine, Dr. Finks and colleagues at the University of Michigan used data from national Medicare claims to evaluate trends in the use of high-volume hospitals for major cancer resections and cardiovascular surgery. The investigators identified patients (aged 65 to 99) who underwent one of the following cancer and cardiovascular operations from 1999 through 2008: 1) esophagectomy, 2) pancreatectomy, 3) lung...
