Predictive value of intracerebral hemorrhage score for stroke-associated pneumonia in patients with primary intracerebral hemorrhage / 中国脑血管病杂志

ABSTRACT

Objective To investigate the predictive value of intracerebral hemorrhage (ICH) score for stroke-associated pneumonia (SAP) in patients with primary intracerebral hemorrhage. Methods From January 2014 to July 2015,209 consecutive patients with ICH at the Emergency Department,Shanghai Jiading District Central Hospital were enrolled retrospectively.The general information of the patients were analyzed. They were divided into either a SAP group (n=73) or a non-SAP group (n=136) according to whether they had SAP or not.Based on the ICH score,the incidence and mortality of SAP were analyzed;the occurrence of SAP was prejudged by ICH score.The ROC curve was plotted,and the sensitivity,specificity and the best cut-off value were calculated. Results (1) The incidence of SAP was 34.9% (73/209) and the mortality was 21.1% (44/209) in patients with ICH.(2) There were significant differences in age (73 ± 12 and 63 ± 14),hematoma volume (23.4 [9.6,51.1] and 6.2 [3.1,16.0],and ICH score (2[1,3] and 1 [0,2]) between the SAP group and the non-SAP group (all P<0.01).Compared with non-SAP group,Glasgow coma scale(GCS) score of the SAP group was significantly decreased(8 [4,11] and 15 [13,15],P<0.01).The area under the ROC curve of the ICH score predicting the occurrence of SAP was 0.775 (95% CI 0.709-0.842,P<0.01).When the maximum Youden index was 0.453,the best cut-off value of the corresponding ICH score was 2,its sensitivity was 74%,specificity was 71%,the positive predictive value was 0.58,and the negative predictive value was 0.84. Conclusions The incidence of SAP in patients with ICH is higher.The ICH score may predict the clinical value of the occurrence of SAP. Clinical attention should be paid to the risk of occurring SAP in patients with ICH whose ICH score≥2.
