ABSTRACT

Objective By investigating the influencing factors and the tendency of devel-opment of 6-year hospitalization costs in our hospital,our hospital explores an appropriate way of analysis on the influencing factors of medical costs,in order to offer some quantifiable evidence of evaluating and meaningful references to controlling medical costs. Methods to use the new method of gray correlation analysis to make the quantitative analysis of the composing of the hospital fees from 2002 to 2007.Results the new method of gray correlation analysis is able to overcome the influence of non-dimensional treatment which affects the role of factors and simplifies the calculation steps. Conclusion It is a statistical analysis method whose result is reasonable and reliable,whose application is flexible and simple. It can also offer a quantifiable index of the tendency of the system of development and changes. It is suitable for measuring the interrelated degree among the factors and the dynamic process of analysis.
