基于GIS和改进DEA模型的医疗资源便利性评价

Evaluating Convenience of Medical Resource Based on GIS and Improved Data Envelopment Analysis Model

科学评价医疗资源的便利性,对于合理配置有限的医疗资源有着重要的现实意义。该文分析了社区医疗资源便利性的评价对象、服务内容、时空维度的特点,分别从医疗机构提供服务的便利性和社区获得服务的便利性两个方面建立评价指标体系。基于数据包络分析(DEA)模型并做无输入改进,提出了医疗资源便利性评价方法。在此基础上,借助GIS的网络分析、叠加分析等功能,考虑道路交通、人口分布及医疗机构分布等空间信息,计算医疗资源便利性评价的指标值。将该方法应用于北京郊区某镇,验证了该方法的有效性。

For allocating the limited medical resource rationally, evaluating the convenience of the medical resource scientifically is important. Firstly, the characters of evaluating objects, service contents, and spatial and temporal dimensions of community medical facility are analyzed. Then the convenience evaluating index system is then built up from the convenience of service which the medical facilities provide and the community acquires respectively. According to the data envelopment analysis （DEA） model, the evaluation index is improved with no-input and the methods of evaluating the convenience of community and medical facility are presented. On the basis of this, taking into account of the road traffic, the distribution of population, and medical facilities, the convenience value of medical resource in town is calculated using the network analysis and overlay functions of GIS. The above method applied in the convenience evaluation of medical resource in Beijing suburbs is validated well
