The government of Taiwan has promoted the hierarchy of medical care in Taiwan in order to facilitate large-scale hospitals returning to the nature of teaching research, emergency and critical care services. Since 2017, the clinical and service growth of mild cases at medical centers and regional hospitals has been limited. This study adopts a retrospective study and uses the clinic application number of the NHI-insured as research subjects. The subject hospital in 2016 applied about 838,088 cases, and after screening about 158,631 people times were included as the research subjects. With the Chi-square test, a significant difference has been identified in age (p<0.001), gender (p<0.001), diagnosis of diabetes, high blood pressure, and hypercholesterolemia (p<0.001), and divisions visited (p<0.001). 2016 Q1’s primary care services rate was 15.18% with the annual average of 18.93% lower than national rate at the same period, 21.76%. Patients of primary care can be transferred by hospitals to community clinics to reduce financial losses. Relevant adoptive measures also need to be introduced by the government (such as policy promotion and adjustment of co-payment) to smoothly promote and develop primary care services.
