Is this trial a fit for you?
✓Likely a good fit
Adults (18+) admitted to the ICU for postoperative monitoring after elective or emergency surgery with at least 24 hours of ICU data or adequate first-24-hour records.
✕Probably not a fit
Patients with incomplete data for the first 24 hours or those not undergoing new postoperative monitoring in the ICU may not benefit from the findings.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a single-center, prospective observational study in a postoperative ICU. It will track all clinically significant complications from hour 0 (ICU admission) through 24 hours, recording the exact time of first onset and grouping events into 0–2, 2–6, 6–8, 8–12, and 12–24 hour windows. No interventions are performed; data come from routine clinical care and standard records. The goal is to determine whether complications cluster early and what portion of the 24-hour burden they represent. Analyses will include cumulative incidence by time window and associations with preoperative and intraoperative factors.
Why it matters
Potential benefit: If successful, the findings could help tailor the intensity and duration of early postoperative monitoring.
How similar studies have gone: Previous observational work has explored timing of complications in critical care, but this study provides prospectively captured, hour-by-hour timing in the immediate postoperative ICU period.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Age 18 years or older * Underwent elective or emergency surgery * Admitted to the intensive care unit for postoperative monitoring after surgery * Monitored in the ICU for at least 24 hours, or sufficient clinical data available for the first 24 hours of monitoring * Time of ICU admission and course of monitoring reliably documented Exclusion Criteria: * Age under 18 years * Pre-existing active organ failure before surgery (for example preoperative acute kidney injury, sustained arrhythmia, requirement for invasive mechanical ventilation) * Admitted to the ICU because of continuing critical illness rather than for monitoring of new postoperative complications * Already an ICU inpatient before surgery and readmitted to the ICU postoperatively * Time of complication onset cannot be reliably determined, or records are inadequate * Incomplete data for the first 24 hours of ICU monitoring * Terminal illness managed with a palliative approach
