Using Exponential Factor Analysis to Evaluate the Impact Factors of Hospitalization Income

Objective To use the index factor analysis method to analyze income changes in hospital departments, and to evaluate the impact and approach of different factors in hospital revenue of in - patients. Method We used basic data of a department, took 2007 as base period and 2008 as reporting period, and analyzed the impact of hospital visits, the average length of stay and average daily cost per person on hospital revenue and their interactions. Result The in income changes of the departments in 2008 depended primarily on changes in daily cost per person, followed by in - patients number.
