| systems analysis | The analysis of an activity, procedure, method, technique, or business to determine what must be accomplished and how the necessary operations may best be accomplished. (12 Dec 1998) |
|---|---|
| systems integration | The procedures involved in combining separately developed modules, components, or subsystems so that they work together as a complete system. (12 Dec 1998) |
| systems theory | Principles, models, and laws that apply to complex interrelationships and interdependencies of sets of linked components which form a functioning whole, a system. Any system may be composed of components which are systems in their own right (sub-systems), such as several organs within an individual organism. (12 Dec 1998) |
| drug delivery systems | Systems of administering drugs through controlled delivery so that an optimum amount reaches the target site. Drug delivery systems encompass the carrier, route, and target. (12 Dec 1998) |
| information systems | Integrated set of files, procedures, and equipment for the storage, manipulation, and retrieval of information. (12 Dec 1998) |
| insulin infusion systems | Portable or implantable devices for infusion of insulin. Includes open-loop systems which may be patient-operated or controlled by a pre-set program and are designed for constant delivery of small quantities of insulin, increased during food ingestion, and closed-loop systems which deliver quantities of insulin automatically based on an electronic glucose sensor. (12 Dec 1998) |
| integrated advanced information management systems | A concept, developed in 1983 under the aegis of and supported by the national library of medicine under the name of integrated academic information management systems, to provide professionals in academic health sciences centres and health sciences institutions with convenient access to an integrated and comprehensive network of knowledge. It addresses a wide cross-section of users from administrators and faculty to students and clinicians and has applications to planning, clinical and managerial decision-making, teaching, and research. It provides access to various types of clinical, management, educational, etc., databases, as well as to research and bibliographic databases. In august 1992 the name was changed from integrated academic information management systems to integrated advanced information management systems to reflect use beyond the academic milieu. (12 Dec 1998) |
| online systems | Systems where the input data enter the computer directly from the point of origin (usually a terminal or workstation) and/or in which output data are transmitted directly to that terminal point of origin. (12 Dec 1998) |
| operating room information systems | Information systems, usually computer-assisted, designed to store, manipulate, and retrieve information for planning, organizing, directing, and controlling administrative activities associated with the provision and utilization of operating room services and facilities. (12 Dec 1998) |
| ecological systems, closed | Systems that provide for the maintenance of life in an isolated living chamber through reutilization of the material available, in particular, by means of a cycle wherein exhaled carbon dioxide, urine, and other waste matter are converted chemically or by photosynthesis into oxygen, water, and food. (12 Dec 1998) |
| emergency medical service communication systems | The use of communication systems, such as telecommunication, to transmit emergency information to appropriate providers of health services. (12 Dec 1998) |
| expert systems | Computer programs based on knowledge developed from consultation with experts on a problem, and the processing and/or formalizing of this knowledge using these programs in such a manner that the problems may be solved. (12 Dec 1998) |
| fire extinguishing systems | Automatic or hand operated equipment used to control and extinguish fires. (12 Dec 1998) |
| life support systems | Systems that provide all or most of the items necessary for maintaining life and health. Provisions are made for the supplying of oxygen, food, water, temperature and pressure control, disposition of carbon dioxide and body waste. The milieu may be a spacecraft, a submarine, or the surface of the moon. In medical care, usually under hospital conditions, life support care is available. (12 Dec 1998) |
