动机：肺炎是一种由肺部感染引起的下呼吸道常见感染。住院时间 (LOS) 是医院活动中最简单、最重要的指标之一，具有不同的用途。本研究的目的是探讨影响医院肺炎患者LOS的重要因素。方法：研究的临床数据集是从2009年至2015年间伊朗一家专科医院的387名患者收集的。患者出院总结包括他们的人口统计信息、入院原因、患者处方药物、实验室检查结果和治疗时间。结果和结论：研究中提出的模型展示了数据处理的各种场景对规模效率模型的影响，该模型指出数据挖掘中预处理的重要性。在这篇文章中，使用了一些方法；值得注意的是，贝叶斯增强方法在识别影响LOS的因素方面取得了更好的结果（准确率95.17%）。此外，研究发现，58%的15岁以下患者和74%的74-88岁老年人更容易患肺炎。此外，研究发现，与大多数年龄组用于治疗肺炎的其他抗生素相比，美罗培南是一种相对更有效的药物。无论各种实验室检查结果（包括 CRP、ESR、WBC、NA、K）的影响如何，美罗培南均导致患者 LOS 降低。 (C) 2017 Elsevier B.V. 保留所有权利。
Motivation: Pneumonia is a prevalent infection of lower respiratory tract caused by infected lungs. Length of stay (LOS) in hospital is one of the simplest and most important indicators in hospital activity that is used for different purposes. The aim of this study is to explore the important factors affecting the LOS of patients with pneumonia in hospitals.Methods: The clinical data set for the study were collected from 387 patients in a specialized hospital in Iran between 2009 and 2015. Patients discharge summary includes their demographic details, reasons for admission, prescribed medications for the patient, the result of laboratory tests, and length of treatment.Results and conclusions: The proposed model in the study demonstrates the way various scenarios of data processing impact on the scale efficiency model, which points to the significance of the pre-processing in data mining. In this article, some methods were utilized; it is noteworthy that Bayesian boosting method led to better results in identifying the factors affecting LOS (accuracy 95.17%). In addition, it was found that 58% of patients younger than 15 years old and 74% of the elderly within the age range of 74-88 were more vulnerable to pneumonia disease. Also, it was found that the Meropenem is a relatively more effective medicine compared to other antibiotics which are used to treat pneumonia in the majority of age groups. Regardless of the impact of various laboratory findings (including CRP, ESR, WBC, NA, K), the patients LOS decreased as a result of Meropenem. (C) 2017 Elsevier B.V. All rights reserved.
