Abstract:
Objective To explore the value of the ratio of hemoglobin to red blood cell distribution width(HRR)in predicting the hospitalization risk of the patients in emergency internal medicine outpatient.Methods The clinical data of the patients in the emergency internal medicine outpatient of this hospital from May to September 2022 were collected;the univariate and multivariate binary logistic regression analysis was used to identify the risk factors for the patients hospitalization.The receive operating characteristics(ROC)curve was drawn,and the area under the curve(AUC)was calculated.Then the restrictive cubic spline(RCS)chart of HRR and the hospitalization risk was drawn and the relationship between HRR and the hospitaliza-tion risk was analyzed.Finally,the patients were divided into the low HRR group and the high HRR group ac-cording to the optimal cut-off value of HRR,the propensity score matching(PSM)was performed based on HRR grouping,and the hospitalization rates after matching were compared between the two groups by using x2 test.Results A total of 2 320 patients were included in this study,in which 791 cases were hospitalized,with an hospitalization rate of 34.1％;the multivariate logistic regression analysis suggested that HRR was an independent influence factor for hospitalization of the patients in the emergency internal medicine department(OR=0.68,95％CI:0.59-0.78,P＜0.05);when the optimal cutoff value of HRR was 9.43,AUC was 0.65;the RCS chart indicated that when HRR≤10.39,the lower the HRR level,the higher the hospitaliza-tion risk for the patients,and the two basically showed the linearly negative correlation.After PSM,the hospi-talization rate in the low HRR group was significantly higher than that in the high HRR group(P＜0.01).Conclusion HRR could be used to predict the hospitalization risk of adult patients in emergency internal med-icine department.The lower the HRR,the higher the hospitalization risk;HRR may be used as a marker to as-sess the disease severity in clinical work.
