Abstract：Objective To explore the early warning signs of infected pancreatic necrosis(IPN)secondary to severe acute pancreatitis(SAP).Methods Clinical data of SAP in Hunan Provincial People's Hospital from 2012 to 2019 were retrospectively analyzed.The demographic characteristics,past medical history,etiology,organ failure,library data in 48 h,and CTSI score at 72 hours after onset were collected.The risk factors of IPN were analyzed by multivariate binary Logistic regression analysis,the ROC curve was used to compare the predictive power of the Logistic regression model,CTSI,BISAP,APACHE Ⅱ,and SOFA scores,and the cutoff value of each score for predicting IPN was analyzed.Results There were 277 SAP patients,74 in the IPN group and 203 in the control group.Logistic regression analysis showed that delirium(OR=4.049,95％CI 1.058～15.500,P=0.041)was a risk factor for IPN,but hematocrit(Het)(OR=0.939,95％CI 0.897～0.983,P=0.007)was a protective factor for IPN.The areas under the ROC curve of the Logistic regression model,CTSI,BISAP,APACHE Ⅱ,and SOFA were 0.719,0.702,0.622,0.593,and 0.561 respectively.The cutoff values of IPN predicted were CTSI ≥ 7 points,BISAP ≥ 3 points,APACHE Ⅱ≥14 points,and SOFA≥5 points respectively.Conclusion Early delirium and decreased Het can predict IPN in the later stage of SAP,and it is recommended to transfer high-risk patients with IPN in time.
