postoperative pulmonary complications : pneumonia
CXR with at least one of the following: infiltrate, consolidation, cavitation;plus at least one of the following: fever \>38 °C with no other cause, white cell count \<4 or\>12\*109 litre-1, \>70 yr of age with altered mental status with no other cause;-plus at least two of the following: new purulent/ changed sputum, increased secretions/suctioning, new/worse cough/dyspnoea/tachypnoea, rales/ bronchial breath sounds, worsening gas exchange.
Time frame: During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days.
postoperative pulmonary complications : prolonged ventilation
Indicate whether the patient had prolonged post-operative pulmonary ventilation \> 24.0 hours. The hours of postoperative ventilation time include OR exit until extubation, plus any additional hours following reintubation.
Time frame: During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days.
postoperative pulmonary complications : reintubation
Indicate whether the patient was intubated for the first time after leaving the OR from the initial procedure, or re-intubated during the hospital stay after the initial extubation.
Time frame: During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days.
postoperative complications : Renal failure
Indicate whether the patient had acute renal failure or worsening renal function resulting in ONE OR BOTH of the following: 1\. Increase in serum creatinine level 3.0 x greater than baseline, or serum creatinine level ≥4 mg/dL , Acute rise must be at least 0.5 mg/dl 2. A new requirement for dialysis postoperatively.
Time frame: During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days.

postoperative complications : Delirium
Indicate whether the patient experienced postoperative delirium from OR Exit to ICU discharge.
Time frame: During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days.
postoperative complications : Reoperation due to bleeding/tamponade
Indicate whether the patient was reexplored for mediastinal bleeding with or without tamponade either in the ICU or returned to the operating room.
Time frame: During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days.
postoperative complications : Permanent stroke
Indicate whether the patient has a postoperative stroke (i.e., any confirmed neurological deficit of abrupt onset caused by a disturbance in blood supply to the brain) that was confirmed on imaging or did not resolve within 24 hours.
Time frame: During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days.
postoperative complications : Mortality
all deaths, regardless of cause, occurring during the hospitalization in which the operation was performed, even if after 30 days (including patients transferred to other acute care facilities)
Time frame: During the hospitalization in which the operation was performed, even if after 30 days.
postoperative complications : Mortality
all deaths, regardless of cause, occurring after discharge from the hospital, but before the end of the 30th postoperative day.
Time frame: After discharge from the hospital, but before the end of the 30th postoperative day.
