Departmental cost functions are constructed for selected hospital departments, using total number of beds in the hospital served as a proxy output measure. Calculation of maxima or minima for the resulting cost functions reveals that, on average, different departments have extremes in their cost functions of different levels of output. A relative cost index is constructed, using parameters of the departmental cost functions, and departmental costs are compared across regions. The significance of departmental differences in optimum output is discussed with regard to sharing of services and modified system design.
使用医院病床总数作为代理产出指标，为选定的医院科室构建部门成本函数。对所得成本函数的最大值或最小值进行计算后发现，平均而言，不同科室在不同产出水平的成本函数中存在极值。利用部门成本函数的参数构建相对成本指数，并对各地区的部门成本进行比较。讨论了部门在最佳产出方面的差异对于服务共享和改进系统设计的意义。
