摘要

本文介绍了一个表示患者生存和费用的模型。贝叶斯网络(BN)理论的扩展被开发来表示这样一个模型,即病人在医院的连续生存时间是相对于病人的临床变量之间的相互关系的图形和概率表示建模。与以前定义的BN技术不同,这个扩展模型可以适应本质上倾斜的连续时间。本文介绍了这种方法背后的理论,并通过将成本变量附加到生存时间来扩展它,使医院患者群体的成本和有效管理成为可能。该模型应用于1994年至1997年间英国一家医院老年病房的4722名患者,对于医院管理者来说,作为一种调查未来决策和政策变化对医院支出影响的方法是有益的。

A Bayesian approach to modelling inpatient expenditure
This paper introduces a model for representing patient survival and cost. An extension of Bayesian network (BN) theory is developed to represent such a model whereby patient's continuous survival time in hospital is modelled with respect to the graphical and probabilistic representation of the interrelationships between the patient's clinical variables. Unlike previously defined BN techniques, this extended model can accommodate continuous times that are skewed in nature. This paper presents the theory behind such an approach and extends it by attaching a cost variable to the survival times, enabling the costing and efficient management of groups of patients in hospital The model, applied to 4722 patients admitted into a geriatric ward of a U.K. hospital between 1994 and 1997, could be beneficial to hospital managers as a method for investigating the influence of future decisions and policy changes on the hospital expenditure.
