Did you know that the most importantand challenging clinical questions
are more likely to be solved if severalcentres join forces ?
Poor quality of surgical outcome data
• Inaccurate healthcare systems data
• Specialty society data on limited subsets
• Mostly retrospective analyses
• Too much focus on elective surgery
• No comparative data across Europe
International seven day cohort study of
standards of care and clinical outcomes
for non-cardiac surgery

European Surgical Outcomes StudyEuSOS
• Large numbers of patients die following in-patient non-cardiac surgery
• Large variations in mortality between countries suggest the need for national and international strategies to improve care for this patient group
• Patterns of critical care admission suggest process failure in the allocation of these resources

Message to be delivered:
Dear Colleagues funding medical care, ……care.
“We suggest that even use of expensiveresources, such as additional ICU beds, could rapidly become cost effective by reducing complications”.

What factors affect mortality after surgery?

Peri-op Mortality and GDP/inhabitant
R = 0.55P < 0.01
MORTALITY (%)
The definition of ICU beds (recovery room vs post-op ICU vs General ICU) and resources might differ between countries
Other factors are important:- Use of surgical safety checklists- Clinical pathways- Enhanced recovery strategy (fast track surgery)- Volume of cases- Presence of general versus specialised surgeons- Ability to recognise and manage complications- Quality of care and Economic resources

PPCs: are they a problem?
• Variable incidence (2%-40%), depending on definition, kind of surgery and patients
• Prevalence: as cardiac complications
• Leading cause of long hospital stay and mortality
• Etiology: anesthesia and surgery induce changes

study
Geographic scope– ARISCAT: 51 Anesthesiology Departments
(Catalonia, Spain)– PERISCOPE: 63 Anesthesiology Departments
(21 European countries)
Methods 2/5
Data collection– 7 days
• ARISCAT: January 2006 – January 2007

Methods 3/5
• Inclusion criteria– Undergoing a surgical procedure under regional
or general anesthesia (epidural, spinal or saddle block) ...
– ... on the selected days at a participating center
– Informed consent
Methods 4/5
• Exclusion criteria– Age < 18 years– Obstetric/childbirth procedures– Local or peripheral nerve anesthesia with or without
sedation– Diagnostic and therapeutic procedures outside the
operating room– Intubated on arrival at the operating room– Re-operation due to an in-hospital postoperative
complication – Transplantss and brain-dead patients

Conclusions
• Postoperative pulmonary complications are frequent, expensive and associated with increased mortality
• There is increased national focus on the need for higher quality, safer and more appropriate care.
• Readmission of surgical patients with pneumonia is a significant source of increased healthcare costs.
Conclusions
• Strongest risk factors for PPCs are age, preoperative SpO2, previous respiratory infection, anemia, kind of surgery and surgical aggressiveness
• More than 50% of the risk is related to patient factors
• A risk index based on 7 objective factors discriminates well across a wide range of patients, surgeries and geographic areas.
• Stratifying risk for PPCs can be calculated preoperatively and, in case, recalibrated.
