Prognostic Utility and Exploratory Cut-off Threshold of the First 24-Hour APACHE II Score for In-Hospital Mortality After Thoracotomy: A Single-Center Retrospective Cohort Study
By Awan Rochaniawan, Ahmat Umar and Erial Bahar.
Abstract
Background
Open thoracotomy imposes severe physiological stress, so objective early risk stratification is needed at General Intensive Care Unit (GICU) admission.
Objective
To evaluate how well the first 24-hour Acute Physiology and Chronic Health Evaluation II (APACHE II) score predicts in-hospital mortality after thoracotomy, to set an exploratory cut-off, and to examine differences by surgical indication and organ component.
Methods
This retrospective cohort study analyzed 33 consecutive adults admitted directly to the GICU of Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia, after open thoracotomy (January–December 2024). Analyses included Mann-Whitney U, Spearman's ρ, logistic regression, and Receiver Operating Characteristic (ROC) analysis with Youden's J index.
