European Surgical Outcomes Study

The European Surgical Outcomes Study (EuSOS) is a multi-centre, international cohort study of peri-operative care and clinical outcomes for patients undergoing non-cardiac surgery. Participating centres throughout Europe will contribute routine clinical data describing all eligible patients who undergo surgery from 4th April 2011 to 11th April 2011. Patients will then be followed until hospital discharge (or for a maximum of 60 days) for duration of hospital stay and hospital mortality. Routine clinical data will also be collected for those patients admitted to critical care at any stage after surgery but during the same hospital admission. Specific objectives are to describe clinical outcomes and standards of peri-operative care for patients undergoing non-cardiac surgery in Europe.
