Applications of Cause-Selecting Control Charts in Hospitals

In a hospital, there are many clinical departments. In general, the hospital management often uses the index of cure rate (i.e. the rate of patients recovered by the cure of this hospital) to evaluate the medical quality of each clinical department. But, since the cure rate varies significantly with the rate of patient with severe disease, the evaluation by cure rate is unreasonable and incomplete. This paper proposes a new evaluation method called the cause-selecting evaluation method proposed by Prof. Gongxu Zhang (1990). Besides, this method can also be used to diagnose the abnormality of cure rate. The practical case studies check with the theory very well.
