Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| postoperative pulmonary complications : pneumonia | During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days. | 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. |
| postoperative pulmonary complications : prolonged ventilation | During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days. | 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. |
| postoperative pulmonary complications : reintubation | During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days. | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| postoperative complications : Permanent stroke | During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days. | 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. |
| postoperative complications : Renal failure | During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days. | 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. |
| postoperative complications : Mortality | During the hospitalization in which the operation was performed, even if after 30 days. | 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) |
| postoperative complications : Delirium | During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days. | Indicate whether the patient experienced postoperative delirium from OR Exit to ICU discharge. |
| postoperative complications : Reoperation due to bleeding/tamponade | During the hospitalization for surgery. This includes the entire postoperative period up to discharge, even if over 30 days. | Indicate whether the patient was reexplored for mediastinal bleeding with or without tamponade either in the ICU or returned to the operating room. |
