Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
2. Non-MDRO patients were selected by random sampling in a ratio of 1:1 to the final MDRO group during the same period , and select the risk factors of infection with multi-drug resistant bacteria by comparing the two groups.
3. Randomly select 30% of the sample size as the validation set, and the remaining 70% for the training set to establish a model. Using multi-factor Logistic regression, decision tree classification, artificial neural network, support vector machine, Bayesian network Method to establish risk assessment system for multidrug-resistant organisms infection respectively.Using validation set data to calculate the area under the ROC curve (AUC) and sensitivity, specificity of models and comparing the prediction accuracy of several models. Finally, choose a more suitable risk assessment system for multidrug-resistant organisms infection.
4. Predict the patient's infection risk level according to the best risk assessment system and develop a low-to-high intervention plan.

MDRO
risk factors of infection with multidrug-resistant organisms
1. General information: age, gender, length of stay in ICU, method of admission, tubes taken at the time of admission, APACHEⅡ score, surgery, laboratory tests (PCT, CRP, WBC), pressure sores, etc.
2. Iatrogenic factors: days of using ventilator, days of using antibacterial drugs, types of antibacterial drugs, use of glucocorticoids, use of immunosuppressants, days of central venous intubation, days of indwelling catheters, days of arterial catheterization, and other indwelling catheters.
3. The patient's own related factors: diagnosis, whether complicated with hypertension or diabetes; whether exist malignant tumor, primary lung infection, hypoproteinemia; whether antibiotic treatment before admission; fever and fever days, whether diarrhea occurs
