摘要:

当我们面对因某种疾病而来到医院的病人时,我们可能遇到的主要问题之一是评估这些病人在不久的将来是否需要重症监护。这种重症监护需要分配宝贵而稀缺的资源,事先了解患者疾病的严重程度可以改善其治疗和资源的组织。我们在第六次流行浪潮中西班牙COVID-19患者的数据集中说明了这个问题,我们将患者标记为危重患者,当他们不得不进入重症监护室或去世时。然后,我们结合使用动态贝叶斯网络,预测生命体征和血液分析结果的患者在未来40小时内,和神经网络,以评估患者疾病的严重程度,在这段时间内。我们的实证结果表明,换位的患者的当前状态,以未来的价值观与DBN为后续使用的分类获得更好的准确性和g-平均得分比直接应用与分类器。

英文摘要:

When we face patients arriving to a hospital suffering from the effects of some illness, one of the main problems we can encounter is evaluating whether or not said patients are going to require intensive care in the near future. This intensive care requires allotting valuable and scarce resources, and knowing beforehand the severity of a patients illness can improve both its treatment and the organization of resources. We illustrate this issue in a dataset consistent of Spanish COVID-19 patients from the sixth epidemic wave where we label patients as critical when they either had to enter the intensive care unit or passed away. We then combine the use of dynamic Bayesian networks, to forecast the vital signs and the blood analysis results of patients over the next 40 hours, and neural networks, to evaluate the severity of a patients disease in that interval of time. Our empirical results show that the transposition of the current state of a patient to future values with the DBN for its subsequent use in classification obtains better the accuracy and g-mean score than a direct application with a classifier.
