论文摘要
皮肤和软组织感染(SSTI)是卧床和医院环境中最常观察到的疾病之一。各种细菌病原体对抗生素的耐药性是严重SSTI的重要原因,治疗失败导致发病率,死亡率和住院成本增加。因此,抗菌监测对于预测抗生素耐药性趋势和监测医疗干预措施至关重要。为了解决这个问题,我们开发了机器学习(ML)模型(深层和常规算法),以使用抗生素易感性测试(ABST)数据在一年内从临床诊断为临床诊断为肾上腺皮肤病的患者中收集的抗生素耐药性(ABST)数据。我们在每个抗菌家族上训练了单独的ML算法,以确定革兰氏阳性球菌(GPC)或革兰氏阴性杆菌(GNB)细菌是否会抵抗相应的抗生素。为此,患者的临床和人口特征以及ABST的数据用于培训。我们在GPC的曲线(AUC)下达到了一个面积,在GNB细菌中达到了0.56-0.93,具体取决于抗微生物家族。我们还进行了相关分析,以确定不同细菌中每个特征和抗菌家族之间的线性关系。 ML技术表明,患者的临床人口统计学特征和抗生素耐药性之间存在可预测的非线性关系。但是,该预测的准确性取决于抗菌家族的类型。
Skin and soft tissue infections (SSTIs) are among the most frequently observed diseases in ambulatory and hospital settings. Resistance of diverse bacterial pathogens to antibiotics is a significant cause of severe SSTIs, and treatment failure results in morbidity, mortality, and increased cost of hospitalization. Therefore, antimicrobial surveillance is essential to predict antibiotic resistance trends and monitor the results of medical interventions. To address this, we developed machine learning (ML) models (deep and conventional algorithms) to predict antimicrobial resistance using antibiotic susceptibility testing (ABST) data collected from patients clinically diagnosed with primary and secondary pyoderma over a period of one year. We trained an individual ML algorithm on each antimicrobial family to determine whether a Gram-Positive Cocci (GPC) or Gram-Negative Bacilli (GNB) bacteria will resist the corresponding antibiotic. For this purpose, clinical and demographic features from the patient and data from ABST were employed in training. We achieved an Area Under the Curve (AUC) of 0.68-0.98 in GPC and 0.56-0.93 in GNB bacteria, depending on the antimicrobial family. We also conducted a correlation analysis to determine the linear relationship between each feature and antimicrobial families in different bacteria. ML techniques suggest that a predictable nonlinear relationship exists between patients' clinical-demographic characteristics and antibiotic resistance; however, the accuracy of this prediction depends on the type of the antimicrobial family.
