Investigation of Risk Factors for Pelvic Infection After Hysterectomy and Construction of Risk Assessment Model
Objective:To investigate the risk factors for pelvic infection after hysterectomy and to construct a risk assessment model.Methods:A total of 200 cases of hysterectomy patients admitted to the hospital from January 2019 to June 2021 were selected and the clinical data of the patients were retrospectively analyzed to count the number of cases of patients with postoperative pelvic infections,which were classified into infected and uninfected groups using the convenience sampling method.The risk factors of pelvic infection after hysterectomy were screened using one-way analysis and multifactorial two-class logistic regression analysis,and the risk assessment model of pelvic infection after hysterectomy was constructed by combining the results of the regression analysis to test the effect of the model assessment.Results:The study was diagnosed and statistically obtained that there were 21 patients with pelvic infection after hysterectomy and the incidence rate was 10.50%.Univariate analysis showed that the risk factors for pelvic infection after hysterectomy were age,comorbidity with diabetes mellitus,receipt of chemotherapy,indwelling urinary catheter time,length of hospitalization,duration of antimicrobials,type of antimicrobials,and related nursing education,and the difference was statistically significant(x2=4.461,23.495,19.834,7.515,4.239,6.121,8.498,5.326;P＜0.05).The results of two-class logistic regression analysis showed that the independent risk factors for pelvic infection after hysterectomy were age≥60 years,comorbid diabetes mellitus,receiving chemotherapy,indwelling urinary catheter≥7 d,antimicrobials≥7 d,antimicrobials≥3 types of medications,and not receiving relevant nursing education,and the difference was statistically significant(P＜0.05).The study constructed a pelvic infection risk assessment model after hysterectomy based on the regression analysis prediction method,and analyzed the ROC curve of the assessment model,obtaining an area under the curve(AUC)of 0.888,a 95%CI of 0.849 to 0.927,a maximum Yoden index of 0.621,and a sensitivity and specificity of 0.880 and 0.741,respectively.The H-L goodness-of-fit test was implemented for the model,and the results showed that the model was well fitted in hysterectomy patients,and the difference was not statistically significant(x2=3.635,P=0.057).The results of the external validation of the risk assessment model showed that the accuracy of the model assessment was 95.56%.Conclusion:Post-hysterectomy patients are accompanied by different degrees of pelvic infection risk,and its risk factors are complex,the study based on the regression analysis results of the construction of the risk assessment model can realize the effective identification of the risk of postoperative pelvic infection of the patient,to provide a reference for clinical preventive care.
