医院管理中,平均病床周转次数、出院者平均住院日和平均病床工作日是评价医疗工作的效率指标。从理论上说,病床周转次数的多少.取决于出院者平均住院日和平均病床工作日的长短。但是,后两个指标对病床周转次数的快慢,影响的程度到底如何?相互之间的关系密切程度如何?本文对我院1980～1983年上述三个指标四十八个月的数据,运用多元回归分析法,计算出平均住院日、平均病床工作日与平均病床周转次数之间定量关系式——回归方程。通过回归方程,可用于计划预测和效率控制。
In hospital management, the average number of hospital bed turnovers, the average length of hospital stay and the average hospital bed workday are the indicators for evaluating the efficiency of medical work. In theory, the number of hospital bed turnovers depends on the average length of hospital discharge and the average length of hospital bed work days. However, what is the extent of the impact of the latter two indicators on the turnover rate of hospital beds and how close they are? This paper applies multiple regression analysis to the data of the above three indicators for 48 months from 1980 to 1983 in our hospital. Method: Calculate the regression equation between the average length of hospital stay, the average bed workday, and the average number of bed turns. Through the regression equation, it can be used for planning and efficiency control.
