Background
The experience of waiting in outpatient is usually the beginning of interaction between patients and hospitals [Scholars and hospital managers have focused on efforts to lessen the actual waiting time (AWT) by improving the medical treatment process [In addition to focusing on the impact of objective factors such as the AWT and the hospital environment, scholars have paid attention to the psychological feelings of patients [Hence, in order to improve patient’s satisfaction and make the adjustment of the EWT can be more maneuverable, based on research before and around the AWT, this paper investigate how much can the EWT be adjusted to attribute a higher satisfaction. The main innovation is that we designed five different experimental groups with extended EWT around the AWT, and compared them with the control group that without the extended EWT one by one. And this experimental is conducted in the hospital and the experimental subjects are the patients.
