Abstract
Progress in the development of a hospital information system that utilizes transaction-oriented distributed processing and an intelligent, fiber-optic-based local area communications network is reported in areas of system requirements, system design components and capabilities, and possible extensions of initial capabilities. A patient registration database organization and associated distributed data processing (DDP) transactions are described. The transactions are examined with respect to DDP functions, and process session controls embedded within a supporting communications network.
The separate development of a fiber-optic information exchange network is described in the areas of system architecture and embedded high level protocols. The ability of the communications network to manage processing sessions between hosts is utilized to manage transaction sessions in the hospital information system design. Installation and evaluation of an operational prototype fiber-optic LACN is planned for 1981 as support for networking four ancillary systems in a university hospital.
