Table 1 Definition of failure-to-rescue variables
Variable | Definition |
|---|---|
Operative mortality | All deaths, occurring during the hospitalization in which the operation was performed, even if after 30 days (including patients transferred to other acute care facilities); and all deaths, occurring after discharge from the hospital until the thirtieth postoperative day |
Prolonged ventilation time | Patients who had prolonged postoperative pulmonary ventilation > 24.0 h. The hours of postoperative ventilation time include OR exit until extubation, plus any additional hours following reintubation |
Stroke | Neurological deficit of abrupt onset caused by a disturbance in blood supply to the brain that did not resolve within 24 h |
Reoperation | Reoperation for any cardiac reason, reexplored for mediastinal bleeding with or without tamponade either in the ICU or returned to the operating room, prosthetic or native valve dysfunction, intervention of coronary graft occlusion due to acute closure, thrombosis, technical or embolic origin, reintervention for Myocardial Ischemia, postoperative aortic reintervention, or other cardiac reasons |
Acute kidney injury | Indicate whether the patient had acute renal failure or worsening renal function resulting in one or both of the following: Increase in serum creatinine level 3.0 × greater than baseline, or serum creatinine level ≥ 4 mg/dL. Acute rise must be at least 0.5 mg/dL, and/or a new requirement for dialysis postoperatively |
