Timing of Complications in the First 24 Hours After Admission to a Postoperative

Sponsor: Kanuni Sultan Suleyman Training and Research Hospital

Summary

The optimal duration and intensity of intensive care monitoring after surgery is largely determined by clinical experience rather than by objective, time-based evidence. This prospective observational cohort study aims to determine how frequently clinically significant complications occur in adult patients admitted to a postoperative intensive care unit (ICU), and - more specifically - when they occur during the first 24 hours after ICU admission. Patients will be followed under standard clinical care, with no additional intervention. The time of ICU admission is defined as hour 0. Complications are recorded with their exact time of first onset, and cumulative incidence is calculated for the predefined windows 0-2, 2-6, 6-8, 8-12 and 12-24 hours. The study will assess whether complications cluster in the early postoperative period (first 6-8 hours) and what proportion of the total 24-hour complication burden this early window represents. A separate analysis will determine how often patients who remain complication-free during the first 6 hours subsequently develop a new, clinically significant complication. The findings are intended to inform evidence-based decisions about the required duration of close postoperative ICU monitoring
