The paper elaborates on the design thinking of the outpatient intelligent medicine delivery system under the two parallel Hospital Information Systems (HIS) of the Central Hospital of Wuhan and implements the distribution of medicine delivery windows based on the multi-channel payment methods of the old HIS outpatient system and the preplanned and real-time intelligent medicine delivery based on the new HIS pharmacy system. Using the integrated platform of Ensemble and services of Web Service, it realizes the data interaction among multiple systems. The system operates steadily and the new HIS is well connected with the old. Thus, the efficiency can be enhanced and the quality can be ensured.
