The Judgment Method and Example of Hospital Return to Scale Based on Data Envelopment Analysis / 中国卫生经济

ABSTRACT

Objective: To judge the return to scale of inefficient decision-making unit(DMU)on data envelopment analysis(DEA). Methods: On the basis of return to scale method of classical DEA decision-making unit. Through comparing the same input of efficient and inefficient DMU, increase the quantities of output of inefficient DMU(the inverse of efficiency value), taking this point as the area of inefficient technique unit return to scale. Results: Taking the county-level hospitals of Chinese Medicine as examples, it is found that there are no clear judgment on the return of scale of inefficient hospitals, after adjustment, there are 4 inefficient hospitals are classified into increasing return to scale stage and decreasing return to scale stage, which embody obvious characteristics of insufficient output. Conclusion: The return to scale is important information to evaluate the efficiency of medical institutions which is the reason leading to inefficiency medical institutions.
