Predicting who will need ICU care after cancer surgery

Comparison of ASA, SORT, CACI, and P-POSSUM Scores for Predicting Postoperative Intensive Care Unit Requirement in Patients Undergoing Oncologic Surgery

Dr Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital · NCT07542925

This study will test common risk scores to see if they can predict which adult cancer surgery patients will need ICU care after their operation.

What this trial studies

This prospective observational cohort will enroll 500 adult patients undergoing elective or emergency oncologic surgery at a single tertiary oncology center. Investigators will record preoperative demographics and clinical data, intraoperative variables, and perioperative factors using a standardized form and capture functional and nutritional measures such as ECOG, NRS-2002, and preoperative serum albumin. Several perioperative risk scores (ASA, SORT, age-adjusted CACI, and P-POSSUM) will be calculated and their performance for predicting planned and unplanned postoperative ICU admission compared using discrimination and calibration metrics. Findings aim to identify which instruments best predict ICU requirement to inform perioperative planning and critical-care resource allocation.

Who should consider this trial

Good fit: Adults (age ≥18) scheduled for elective or emergency oncologic surgery at the enrolling center who can provide written informed consent are the intended participants.

Not a fit: Patients already requiring continuous ICU care before the current surgery, pediatric patients under 18, or those treated outside the enrolling center are unlikely to receive direct benefit from this study's predictions.

Why it matters

Potential benefit: If successful, clinicians could more accurately identify patients who need postoperative ICU care, improving patient safety and helping hospitals allocate critical care beds more efficiently.

How similar studies have performed: While ASA, SORT, Charlson indices and P-POSSUM have been used to predict surgical risk and outcomes, prospective head-to-head comparisons specifically for postoperative ICU requirement in oncologic populations are limited.
