Observational study on postoperative ICU care

Observational Study for Perioperative Care of Patients Requiring ICU (OPICU)

Observational Koç University · NCT05995925

This study looks at how patients who have major surgeries are cared for in the ICU to see if some could be treated in less intensive settings and to understand what factors might predict their need for ICU care.

What this trial studies

This observational cohort study will be conducted across multiple centers in Turkey to evaluate the utilization of ICU beds for postoperative patients. The research aims to compare the treatment outcomes of patients requiring planned versus unplanned ICU admissions, assessing whether some patients could be monitored in less intensive care settings. The study will also identify preoperative characteristics that predict ICU needs and evaluate postoperative complications using the Clavien-Dindo classification. By focusing on patients over 18 years undergoing major surgeries, the study seeks to optimize ICU resource allocation.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years undergoing major elective or emergency surgical procedures requiring postoperative care.

Not a fit: Patients undergoing day-case surgery, cardiac surgery, or pediatric surgery will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more efficient use of ICU resources, improving patient care and outcomes.

How similar studies have performed: While similar studies have explored ICU utilization, this specific approach focusing on postoperative triage is relatively novel.
