CCOW is the primary standard protocol in healthcare to facilitate a process called "context management". Context management is the process of using particular "subjects" of interest (e.g., user, patient, clinical encounter, charge item, etc.) to virtually link disparate applications so that the end-user sees them operate in a unified, cohesive way.
Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
An example from the healthcare industry where Context Management is widely used, multiple applications operating "in context" through use of a context manager would allow a user to select a patient (i.e., the subject) in one application and when the user enters the other application, that patient's information is already pre-fetched and ...
A context model (or context modeling) defines how context data are structured and maintained (It plays a key role in supporting efficient context management). [1] It aims to produce a formal or semi-formal description of the context information that is present in a context-aware system. In other words, the context is the surrounding element for ...
The context diagram serves the purpose of "establish[ing] the information boundary between the system being implemented and the environment in which the system is to operate." [1] Further refinement of the context diagram requires analysis of the system designated by the shaded rectangle through the development of a system functional flow block ...
When problem analysis is incorporated into the software development process, the software development lifecycle starts with the problem analyst, who studies the situation and: creates a context diagram; gathers a list of requirements and adds a requirements oval to the context diagram, creating a grand "all-in-one" problem diagram.
A clinical decision support system (CDSS) is a health information technology that provides clinicians, staff, patients, and other individuals with knowledge and person-specific information to help health and health care. CDSS encompasses a variety of tools to enhance decision-making in the clinical workflow.
Structure describes the context in which care is delivered, including hospital buildings, staff, financing, and equipment. Process denotes the transactions between patients and providers throughout the delivery of healthcare. Finally, outcomes refer to the effects of healthcare on the health status of patients and populations. [2]
