Secondary
| Measure | Time frame |
|---|---|
| Composite outcome of in-hospital postoperative atrial fibrillation (POAF) or all-cause in-hospital mortality. The event is defined as the occurrence of either component; each component (POAF and mortality) is also analyzed individually to assess the validity of the interpretation.;Cumulative opioid consumption within 12 hours after surgery, expressed as Morphine Milligram Equivalents (MME). All intravenous and oral opioids documented in the medical records are converted to MME using standard conversion factors and summed.;Performance of direct current cardioversion (DCCV) for in-hospital postoperative atrial fibrillation, ascertained by medical record review.;Time from the end of surgery to tracheal extubation in the intensive care unit or recovery room (in hours), assessed by medical record review.;Occurrence of postoperative delirium during the in-hospital period, defined as a delirium diagnosis documented by the clinical team or a positive assessment using a standardized tool (e.g., Confusion Assessment Method for the Intensive Care Unit, CAM-ICU) recorded in the medical records.;Length of stay in the intensive care unit (ICU), measured from ICU admission after surgery to transfer to the general ward, ascertained by medical record review.;Total hospital length of stay (HLOS) measured in days, from the date of surgery to the date of hospital discharge. | — |
