Efficacy of Various Scoring Systems for Predicting the 28-Day Survival Rate among Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease Requiring Emergency Intensive Care

Table 4

Comparison of the ROC areas of the APACHE II and SAPS II scores and their ability to predict the 28-day survival rate in patients with AECOPD requiring emergency critical care.

	AUC	SE	95% CI		statistics	value
			Lower	Upper
Model I	0.899	0.030	0.856	0.942	−0.706	1.519
Model II	0.862	0.043	0.811	0.912

Model I included APACHE II scores, age, coronary heart disease, and heart failure; Model II included SAPS II, coronary heart disease, and heart failure; CI, confidence interval; SAPS, Simplified Acute Physiology Score; APACHE, Acute Physiology and Chronic Health Evaluation II; SE, standard error, AUC, area under the receiver operating characteristic curve.
