Research on the Construction Method of the Hospital Information System Hourglass Model

The informatization construction of modern health care has gradually shifted from “hospital informatization” around 1993 to “health care intelligentization”. The studies on Hospital Information System (HIS) are carried out from multiple perspectives: research review, theoretical proposal and case application. Based on user experience elements and Actor-Network Theory, the construction method of HIS “hourglass model” is proposed. The hourglass model consists of three parts: the upper structure composed of the hospital ethnographic research and the definition of medical staff’s requirements, the connected pipeline structure composed of HIS architecture design, and the lower structure composed of HIS interaction and visual design and HIS design evaluation. By expounding the complete development process of the nurse station service system, the reproducibility of the hourglass model construction method is proven, and the three structures of the hourglass model are refined, providing reference solutions for the subsequent development and research of agile projects.
