An observational study in Postoperative Intensive Care Unit Admission and Perioperative Risk Assessment, sponsored by Van Training and Research Hospital. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-20.
Sponsored by Van Training and Research Hospital · Observational
This prospective observational pilot study will evaluate how accurately anesthesiologists can predict, before a procedure, whether an adult patient will require admission to an intensive care unit (İCU) after surgery or an endoscopic procedure.
Before each procedure, the anesthesiologist will record whether postoperative intensive care unit (İCU) care is expected and the clinical factors influencing this assessment. No changes will be made to the patient's usual medical care. After the procedure, the researchers will record whether the patient was admitted to the İCU and whether the admission was planned or unplanned. Additional information, including İCU and hospital length of stay, need for organ support, and in-hospital mortality, will also be collected when applicable.
The pilot study will also assess whether the planned data collection process is practical and whether the required study information can be collected completely before conducting the main prospective study.
Van Training and Research Hospital is the lead sponsor of 8 studies on the registry; 5 are open to participants now.
Counted across the registry records on this site, refreshed daily.
The study population will consist of adult patients undergoing eligible surgical or endoscopic procedures in the participating operating rooms and endoscopy units on the predefined study days. Patients with The american society of anesthesiologists (ASA) Physical Status of I-II will be included if they undergo a major procedure, while patients with ASA Physical Status of III-V will be considered for inclusion regardless of procedural magnitude, provided that all other eligibility criteria are met. Preoperative clinical assessment will be completed before the procedure, and postoperative outcomes will be recorded prospectively.

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Adult patients undergoing eligible surgical or endoscopic procedures on the predefined study days will be included in this prospective observational cohort. Before each procedure, the anesthesiologist will record whether postoperative intensive care unit admission is anticipated. Actual intensive care unit (İCU) admission and other postoperative outcomes will subsequently be recorded. No study-specific intervention will be performed.
Other: Preoperative Clinical Prediction of Postoperative ICU Admission
Before the index procedure, the anesthesiologist will record whether postoperative intensive care unit admission is anticipated based on routine preoperative clinical assessment. This assessment is observational and will not alter routine patient care.
Accuracy of Preoperative Prediction of Postoperative Intensive Care Unit Admission
Overall prediction accuracy will be calculated as the proportion of evaluable patients for whom the anesthesiologist's preoperative prediction of postoperative intensive care unit (İCU) need agrees with actual İCU admission status within 24 hours after the index procedure. Patients with mandatory postoperative İCU admission according to institutional protocol will not be included in this primary analysis.
Time frame: Within 24 hours after the index surgical or endoscopic procedure
Unanticipated Postoperative Intensive Care Unit Admission
The proportion of evaluable patients who are admitted to the intensive care unit (İCU) within 24 hours after the index procedure despite postoperative İCU care not being anticipated during the preoperative anesthesiology assessment.
Time frame: Within 24 hours after the index surgical or endoscopic procedure
