我国区域平均住院日与医院运行效率相关性研究

目的 测算我国医院运行效率,并研究其与平均住院日的相关性,探讨缩短平均住院日对提高医院运行效率的重要性及相关政策建议。 方法 基于2003年至2012年我国31个省、自治区、直辖市的省级面板数据,采用超效率数据包络分析方法测算医院运行效率;运用Spearman秩相关系数检验全国及各地区医院运行效率与平均住院日的相关性。 结果 2003年至2012年的全国医院运行效率均值上升较为缓慢,多数地区的医院处于运行非效率状态;从全国整体情况看,医院运行效率与平均住院日呈显著负相关;但不同地区间相关性并不一致,中西部地区医院运行效率与平均住院日呈显著负相关,且中部相关性更强,而东部地区医院运行效率与平均住院日的相关性并不显著。 结论 科学合理设置平均住院日,以效率的改进带动社会效益和经济效益的提升;不同区域应因地制宜提升医院运行效率;有效缩短无效住院日。

Study on the correlation between regional average length of stay and hospital operation efficiency of China

Objective To measure the hospital operation efficiency and study the correlation between average length of stay and hospital operation efficiency. To explore the importance of shortening average length of stay to the improvement of the hospital operation efficiency and put forward relevant policy suggestion. Methods Based on China provincial panel data from 2003 to 2012,the hospital operation efficiencies were calculated using Super Efficiency Data Envelopment Analysis model,and the correlation between average length of stay and hospital operation efficiency was tested using Spearman rank correlation coefficient test. Results From 2003 to 2012,the average of national hospital operation efficiency was increasing slowly and the hospital operations were inefficient in most of the regions. The national hospital operation efficiency was negatively correlated with the average length of stay. But the correlations between different regions were not consistent. In middle and western areas,hospital operation efficiencies were negatively correlated to the average lengths of stay. The coefficient in middle area was higher than the coefficient in the western area,whereas the hospital operation efficiency was not correlated with the average length of stay in the eastern area. Conclusion Measures should be taken to set average length of stay in a scientific and reasonable way,and improve social and economic benefits based on the improvement of efficiency.Furthermore,measures should be taken to promote hospital operation efficiency with different measures in different regions,and shorten the inefficient average length of stay.
