Paragraph on background/aims and objectives

In 2006, in Catalonia, a prospective study on postoperative outcome in a representative general surgical population (ARISCAT study) found a 5% incidence of PPC. The 30-day mortality of patients with PPC was 20%. The ARISCAT also identified nine independent risk factors for PPC (age, male sex, low preoperative SpO2, acute respiratory infection during the previous month, preoperative anaemia, positive cough test, upper abdominal or intrathoracic surgery, surgical duration ≥2 hours and emergency surgery). A simplified risk score was derived for each variable. The main objective is to validate a risk index based on nine objective and easily assessed factors, described in the ARISCAT study, in a general unrestricted surgical population across Europe, to predict PPC in any clinical setting accurately. Secondarily, this multinational prospective study will allow knowing the variability of the PPC rate among the different countries in Europe.
