Surgery meets Anesthesiology

Lancet 2012; 380: 1059–65

European Surgical Outcomes Study (EuSOS) group for the Trials groups of the European Society of Intensive Care Medicine and the European Society of Anaesthesiology

Lancet 2012; 380: 1059–65

Methods:• 7 day cohort study• Consecutive patients aged ≥16 years • Inpatient non-cardiac surgery• 498 hospitals• 28 European nations• Patients followed up to 60 days• Primary endpoint in-hospital mortality• Secondary outcome LOS and ICU

admission

Lancet 2012; 380: 1059–65

Results:• 46 539 patients

• 1855 (4%) died before hospital discharge• 3599 (8%) patients were admitted to critical

care• median LOS of 1・ 2 days (IQR 0・ 9–3・

6) • 1358 (73%) patients who died were not

admitted to critical care at any stage after surgery.

• Crude mortality rates between countries (from 1.2% for Iceland to 21.5% for Latvia)

Conclusion:The mortality rate for patients undergoing inpatient non-cardiac surgery was higher than anticipated.

Variations in mortality between countries suggest the need for national and international strategies to improve care for this group of patients.

• 84,730 patients • Inpatient general and vascular surgery• Data from the American College of Surgeons National

Surgical Quality Improvement Program (NSQIP)• Hospitals ranked according to risk-adjusted overall rate of

death• Divided into five groups

Each overall mortality quintile assessed the incidence of overall and major complications and the rate of death among patients with major complications.

CONCLUSION“In addition to efforts aimed at avoiding complications in the first place, reducing mortality associated with inpatient surgery will require greater attention to the timely recognition and management of complications once they occur.”

Preventing CLABSI

“To really make progress, need cooperation of

vendors, clinicians and administrators.”

Implement known patient safety practices.

Get vendors to provide open access to data.

Significant Financial Implications

Over a 12 month period decreased transfers to the ICU from 54 to 28 for one unit.

With an average LOS of 6.3 days, translates into 163 ICU days saved
