Optimizing post anesthesia care unit admission after elective craniotomy for brain tumors: a cohort study

Area of Science:

• Neurosurgery
• Anesthesiology
• Critical Care Medicine

Background:

• Postoperative intensive care unit (ICU) admission following craniotomy for brain tumors was historically standard practice.
• Evidence supporting routine ICU admission is limited, prompting reevaluation of this approach.
• The study aims to identify risk factors for ICU admission to enable individualized patient care.

Purpose of the Study:

• To identify and validate risk factors for intensive care unit (ICU) admission after elective brain tumor surgery.
• To develop a predictive scoring system for tailored ICU admission decisions.

Main Methods:

• Retrospective cohort study of 420 patients undergoing elective brain tumor surgery over six years.
• Patients were divided into training (2/3) and validation (1/3) cohorts for risk factor identification and testing.
• Univariate and multivariate logistic regression were used to develop and validate a scoring system.

Main Results:

• American Society of Anesthesiologists physical status (ASA-PS), tumor volume, and surgery length were identified as key factors.
• The developed scoring system demonstrated an Area Under the Curve (AUC) of 0.774 in sensitivity analysis.
• The optimal threshold for ICU admission based on the scoring system was determined to be 12.5.

Conclusions:

• A novel tool incorporating ASA-PS, surgery length, and tumor volume can assess ICU admission risk after supratentorial tumor resection.
• This tool facilitates individualized ICU admission decisions, moving away from routine practice.
• Further prospective studies are recommended to validate the developed scoring system.
