The purpose of this study was to evaluate the clinical usefulness of the Critical Patient Severity Classification System (CPSCS) and Glasgow Coma Scale (GCS) for critically ill neurological patients and to determine the applicability of CPSCS and GCS in predicting their mortality.
Data were collected from the medical records of 187 neurological patients who were admitted to the intensive care unit of C university hospital. The datawere analyzed through chi-square test, t test,Mann-Whitney, Kruskal-Wallis, goodness-of-fit test, and receiver operating characteristic curve.
In accordance with patients' general and clinical characteristics, patient mortality turned out to be significantly different depending on intensive care unit stay, endotracheal intubation, central venous catheter, and severity by CPSCS. Hosmer-Lemeshow goodness-of-fit tests were applied to CPSCS and GCS. The results of the discrimination test using the receiver operating characteristic curve were CPSCS0, .743, GCS0 .583, CPSCS24, .734, GCS24 .612, CPSCS48, .591, GCS48 .646, CPSCS72, .622, and GCS72 .623. Logistic regression analysis showed that each point on the CPSCS score signifies a 1.034 higher likelihood of dying.
Applied to neurologically ill patients, early CPSCS scores can be regarded as a useful tool.
