摘要
目的:探讨多水平模型分析纵向研究数据的适用性。方法:应用多水平模型分析山东省和河南省不同级别的45家医院8个年度的业务收入水平。结果:两省间医院业务收入水平及其增长速度和增长加速度的差别无统计学意义,而省内不同级别医院间的差别具有统计学意义。结论:多水平模型可以有效地分析具有层次结构的、含有缺失值的纵向数据资料。
Objective： To explore the applicability of a multilevel model in longitudinal data. Methods： The income of 45 hospitals with different grades for 8 years in Shandong and Henan Provinces was assessed by a multilevel model. Results： The multilevel model showed that differences of the hospital professional income and velocity and acceleration of increase were not significant between the two provinces, but they were significant in various grades. Conclusion： Multilevel models can efficiently analyze longitudinal data with hierarchical structure and missing data.
