Abstract:Objective: To study the prognostic value of neutrophil-lymphocyte ratio (NLR) for predicting prognosis in critical ill patients. Methods: Adult patients who admitted our ICU from Jan. 2012 to Sep. 2013 and met inclusion criteria were included. NLR, PCT, APACHEII scores and SOFA scores according to the classification of different outcomes were compared. Univariate and multiple logistic regression analysis were used to identify potential independent risk factors for mortality. The performances of NLR in predicting mortality was assessed by receiver operating curves (ROC) and diagnostic parameters. The survival curves grouped by cut-off value of NLR were compared by using Kapla-Meier method. Results: Two hundred patients were included, among which 144 patients were male and the other 56 patients were female. According to classification of different outcomes, NLR in different groups had significant differences (P<0.05). NLR [1.10(1.04-1.16), p<0.001] and APACHEII scores [1.10(1.01-1.20), P<0.001] were the independent risk factors for mortality. The ROC of NLR for predicting mortality was 76.2% and the cut-off value was 4.92. Patients with NLR more than 4.92 had significantly lower survival rates than those with NLR less than 4.92 (P=0.002). Conclusion: NLR is an effective predictor of clinical outcomes in critical ill patients.
