基于瓦瑟斯坦距离的分段分析和排队参数恢复：慢性阻塞性肺疾病患者管理数据的研究
Segmentation analysis and the recovery of queuing parameters via the Wasserstein distance: a study of administrative data for patients with chronic obstructive pulmonary disease
摘要：
这项工作使用数据驱动的方法来分析慢性阻塞性肺疾病（COPD）患者的资源需求如何变化，量化这些变化如何影响与患者互动的医院系统。这种方法是由一种新颖的组合，往往不同的分析模式：分割，操作排队论，并从不完整的数据恢复参数。通过结合本文所述的这些方法，这项工作表明可以克服细粒度数据可用性的潜在限制。因此，尽管只使用行政数据，也能找到有用的业务结果。本文首先找到一个有用的聚类的人口从这个粒状数据，饲料到多类M/M/C模型，其参数从数据中恢复通过参数化和瓦瑟斯坦距离。然后，该模型用于通过几个假设情景对潜在的排队系统和研究中的人口需求进行信息分析。用于形成和研究该模型的分析实际上考虑了所有类型的患者到达以及这些类型如何影响系统。因此，这项研究发现，没有快速的解决方案来减少COPD患者对系统的影响，包括增加系统的容量。在这项分析中，减少COPD患者造成的压力的唯一有效干预措施是制定外部政策，在COPD患者到达医院之前直接改善他们的整体健康状况。
英文摘要：
This work uses a data-driven approach to analyse how the resource requirements of patients with chronic obstructive pulmonary disease (COPD) may change, quantifying how those changes impact the hospital system with which the patients interact. This approach is composed of a novel combination of often distinct modes of analysis: segmentation, operational queuing theory, and the recovery of parameters from incomplete data. By combining these methods as presented here, this work demonstrates that potential limitations around the availability of fine-grained data can be overcome. Thus, finding useful operational results despite using only administrative data. The paper begins by finding a useful clustering of the population from this granular data that feeds into a multi-class M/M/c model, whose parameters are recovered from the data via parameterisation and the Wasserstein distance. This model is then used to conduct an informative analysis of the underlying queuing system and the needs of the population under study through several what-if scenarios. The analyses used to form and study this model consider, in effect, all types of patient arrivals and how those types impact the system. With that, this study finds that there are no quick solutions to reduce the impact of COPD patients on the system, including adding capacity to the system. In this analysis, the only effective intervention to reduce the strain caused by those presenting with COPD is to enact external policies which directly improve the overall health of the COPD population before they arrive at the hospital.
