目的:探讨宁夏县级医疗机构床位数的变化对机构规模效率的影响,从而发现宁夏县级综合医院适宜的规模。方法:以医疗机构的实际开放床位数作为衡量医疗机构规模的一个主要指标,将所有宁夏县级综合医院纳入研究,搜集2000—2012年的宁夏县级综合医院的投入和产出数据,以DEA-CCR、DEA-BCC计算决策单元的综合技术效率、纯技术效率、规模效率;利用曲线回归分析(curve estimation)探索宁夏县级综合医院的适宜规模。结果:发现实际开放床位数与医疗机构的规模效率得分呈现三次方关系,当实际开放床位数介于[120,220]时,规模效率得分基本处于最高阶段,因此宁夏县级综合医院目前最适宜的床位规模是120~220张。结论:按照区域卫生规划控制县级医疗机构的规模。
Objective: To explore the impact of the changes of the number of beds in Ningxia county-level medical institutions on the scale efficiency of the institutions, so as to find out the suitable scale of Ningxia county-level general hospitals. Methods: Taking the actual number of open beds in medical institutions as a major index to measure the scale of medical institutions, all county-level general hospitals were included in the study to collect input and output data of Ningxia county-level general hospitals from 2000 to 2012. With DEA -CCR and DEA-BCC to calculate the comprehensive technical efficiency, pure technical efficiency and scale efficiency of decision-making unit; and explore the suitable scale of Ningxia county-level general hospital by means of curve estimation. Results: The results showed that the actual number of open beds and the scale of medical institutions showed a cubic power relations, when the actual number of open beds between [120,220], the scale efficiency score at the highest level, so the most suitable beds in Ningxia County General Hospital The scale is 120 ~ 220 pieces. Conclusion: The scale of county-level medical institutions is controlled according to regional health plans.
