Enterprise Health Information Systems
Health care institutions generate massive volumes of information that must be collected, transmitted, recorded, retrieved, and summarized. The problem of managing all these activities for clinical information has become monumental. As a result, computer based hospital information systems (HISs) were designed, tested, and installed in hospitals of all sizes. The original purpose of HISs was to provide a computer-based framework to facilitate the communication of information within a hospital setting. Essentially, an HIS is a communication network linking terminals and output devices in key patient care or service areas to a central processing unit that coordinates all essential patient care activities. Thus, the HIS provides a communication system between departments (e.g., dietary, nursing units, pharmacy, laboratory, etc.); a central information system for receipt, sorting, transmission, storage, and retrieval of information; and a high speed, data processing system for fast and economic processing of data to provide information in its most useful form.
