Development Of Hospitalization Subsystem Of Information Systems Of The Frist Affiliated Hospital Of Zhengzhou University

The hospital information management system (HIS) is an important branch of modern medical information science. It belongs to the most complicated type of the enterprise scope information system. According to the need of hospital information management system and development, based on studying domestic and international development process and present condition, unifying with the hospital HIS characteristic and system construction, this paper optimizes the database design. After being carried into execution, this system realizes real time dynamic link with ZHENGZHOU HEALTH CARE CENTER on the whole, bases a foundation that many servers compos into a servers group. This system realizes typical 7 days/24 hours running without a breaking, realizes goodly to unify the management with patients' expenses to the hospital medical treatment information. Moreover, since database of the system adopts double hot-backup and redundancy backup technique, insuring that the system runs long-term safely, firmly and stably.By analyzing the problems appeared in the system run-time, this project group find out the bottleneck of the system affecting response speed, gives a concrete measure for system performance optimization. By the root, that project avoids massive data transmissions in the network when multi-tables union-inquiry, makes the processing logic distributing reasonably between the Client end and the Server end. At the same time, this system makes use of optimization configuration to improve the running response speed in data handle, commendably resolves the problem in slowly running response speed.This system has already run successfully at The First Affiliated Hospital of Zhengzhou University, the hospital management has been promoted. Yearly in-patient number increases 30% than before, amounting to 50000 people times. Yearly traffic income increases 35%. The hospital is the biggest modern general hospital of medicine, teaching, research and prevention currently in out province, which result in good social and economic efficiency.
