| multi-institutional systems | Institutional systems consisting of more than one health facility which have cooperative administrative arrangements through merger, affiliation, shared services, or other collective ventures. (12 Dec 1998) |
|---|---|
| point-of-care systems | Laboratory and other services provided to patients at the bedside. These include diagnostic and laboratory testing using automated information entry systems. (12 Dec 1998) |
| health systems agencies | Health planning and resources development agencies which function in each health service area of the united states (pl 93-641). (12 Dec 1998) |
| health systems plans | Statements of goals for the delivery of health services pertaining to the health systems agency service area, established under pl 93-641, and consistent with national guidelines for health planning. (12 Dec 1998) |
| hemic and immune systems | The organs involved in the production and functions of the blood and the cellular and molecular components providing defense against foreign organisms or substances. (12 Dec 1998) |
| second messenger systems | Systems in which an intracellular signal is generated in response to an intercellular primary messenger such as a hormone or neurotransmitter. They are intermediate signals in cellular processes such as metabolism, secretion, contraction, phototransduction, and cell growth. Examples of second messenger systems are the adenyl cyclase-cyclic AMP system, the phosphatidylinositol diphosphate-inositol triphosphate system, and the cyclic GMP system. (12 Dec 1998) |
| neurosecretory systems | A system of neurons that has the specialised function to produce and secrete hormones, and that constitutes, in whole or in part, an endocrine organ or system. (12 Dec 1998) |
| database management systems | Software designed to store, manipulate, manage, and control data for specific uses. (12 Dec 1998) |
| decision support systems, clinical | Computer-based information systems used to integrate clinical and patient information and provide support for decision-making in patient care. (12 Dec 1998) |
| decision support systems, management | Computer-based systems that enable management to interrogate the computer on an ad hoc basis for various kinds of information in the organization, which predict the effect of potential decisions. (12 Dec 1998) |
| 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) |
