Comparison of mean death rates for elective open abdominal aortic aneurysm (AAA) and endovascular AAA repair (EVAR) in California hospitals meeting Leapfrog standards for the 3-year periods during ear

Comparison of mean death rates for elective open abdominal aortic aneurysm (AAA) and endovascular AAA repair (EVAR) in California hospitals meeting Leapfrog standards for the 3-year periods during early (2000-2002) and later (2003-2005) phases of initiative. A significant decrease in mean death rates after open AAA repair was observed in the later time period for hospitals that implemented a policy for routine perioperative β-blocker use. In comparison, mortality rates after open AAA repair for control hospitals and those meeting Leapfrog case volume standards trended higher over consecutive time periods. Average in-hospital death rates after EVAR cases trended lower for all hospital groups over time, although the greatest reduction in mortality was observed among hospitals that met AAA case volume. Error bars represent the standard error of the mean.

Comparison of mean hospital length of stay for abdominal aortic aneurysms (AAA) repaired electively by open and endovascular (EVAR) techniques in California hospitals meeting Leapfrog standards for early (2000-2002) and later (2003-2005) phases of the initiative. No decrease in hospital length of stay over time after open AAA repair was observed among control hospitals and those meeting β-blocker and case volume standards. In comparison, hospital length of stay after EVAR cases decreased over consecutive time periods to a similar extent among both control hospitals and those meeting Leapfrog standards. Error bars represent the standard error of the mean.
