研究目的: |
依据抗生素联合用药回顾性病例研究队列,结合关键临床结局指标对抗生素联合用药的临床疗效展开判定,提取临床常用抗生素用药组合,针对其中的抗生素用药组合和有效性情况展开机器学习,构建抗生素联合用药人工智能预测评价模型,以其为感染相关病例的临床抗生素联合用药提供临床用药依据支撑。 |

Objectives of Study: |
According to the retrospective case study cohort of antibiotic combination, the clinical efficacy of antibiotic combination was judged based on key clinical outcome indicators, the combination of antibiotics commonly used in clinical practice was extracted, machine learning was carried out according to the combination and effectiveness of antibiotics, and an artificial intelligence prediction and evaluation model of antibiotic combination was constructed, so as to provide clinical basis support for clinical antibiotic combination in infection-related cases. |

药物成份或治疗方案详述: |
1. 临床抗生素联合用药信息收集与疗效判定 收集临床细菌感染病例抗生素用药信息,患者主诊断、感染部位等临床信息和临床关键结局炎症相关指标:降钙素原、C-反应蛋白、白细胞计数;关键体征指标:体温;关键影像学指标和微生物学检测结果,通过关键结局指标的变化情况判断临床抗生素联合用药的有效性。 2. 抗生素联合用药组合的临床证据等级判定 提取抗生素联合用药组合;去除重复组合。结合出现频次和有效例数计算联合用药有效率,对抗生素用药组合的临床医学证据水平进行分级。 3. 临床联合用药组合深度学习模型的建立 将获得的临床多中心抗生素联合用药数据分为模型学习训练组和验证组,基于抗生素组合的有效性证据级别和公共数据库药物信息提取,采用eXtreme gradient boosting (XGBoost),logistic regression (LR),support vectormachine (SVM)算法整合多指标信息药物组合合理性人工智能辨识模型。以学习训练组的临床抗生素联合用药组合信息作为学习集进行模型训练。 4. 深度学习模型的临床回归验证 以前期临床多中心抗生素联合用药验证组数据,导入建立的模型进行结果预测,通过对比预测结果和实际结果,对预测模型的准确性进行验证,并通过拟合参数的调整,对模型进行修正。 |

Description for medicine or protocol of treatment in detail: |
1. Collection of clinical antibiotic combination information and judgment of efficacy Antibiotic medication information of clinical bacterial infection cases was collected, clinical information such as the main diagnosis of patients, site of infection and inflammation-related indicators of key clinical outcomes: PCT, C-reactive protein, WBC; Key signs: body temperature; Key imaging indexes and microbiological test results, and the effectiveness of clinical antibiotic combination was judged by the change of key outcome indicators. 2. Determination of clinical evidence level of antibiotic combination Extraction of antibiotic combinations and remove duplicate combinations. The effective rate of combination medication was calculated by combining the frequency of occurrence and the number of effective cases, and the level of clinical evidence for antibiotic combination was graded. 3. Establishment of deep learning model for clinical antibiotics combination The obtained clinical multicenter antibiotic combination data were divided into model learning training group and validation group, based on the effectiveness evidence level of antibiotic combination and public database drug information extraction, using eXtreme gradient boosting (XGBoost), logistic regression (LR), support vectormachine (SVM) The algorithm integrates multi-index information and rationality of drug combination artificial intelligence identification model. The model training was carried out by using the clinical antibiotic combination information of the learning training group as the learning set. 4. Clinical regression validation of deep learning models The data of the multicenter antibiotic combination validation group in the previous phase clinical trial were imported into the established model for result prediction, and the accuracy of the prediction model was verified by comparing the prediction results and the actual results, and the model was modified through the adjustment of fitting parameters. |
