Interoperability
the capability of two or more computer systems to share data and resources, even though they
are made by different manufacturers
AHRQ
Agency for Healthcare Research and Quality
CCC
Clinical Care Classification, classification system of nursing diagnoses and interventions for home
health
Change Theory
The study of change in individuals or social systems such as organizations.
,Channel
A physical element that carries a message between a sender and a receiver. Examples of
channels are radio waves, fiber optic lines, and paper.
Chaos Theory
The qualitative study of unstable aperiodic behavior in deterministic, nonlinear dynamical
systems
Clinical Informatics
The application of informatics and information technology to deliver healthcare services.
Closed System
A system that is enclosed in an impermeable boundary and does not interact with the
environment.
QI
quality improvement
Complex Adaptive Systems (CAS)
, An entity consisting of many diverse and autonomous parts that are interrelated,
interdependent, linked through many interconnections, and behave as a unified whole in
learning from experience and in adjusting to changes in the environment
Complexity Theory
Complexity theory builds on chaos theory using a qualitative approach to the study of dynamic
nonlinear social systems that change with time and demonstrate complex relationships.
Computerized provider order entry (CPOE)
A system that automates the way that orders have traditionally been initiated for patients.
Clinicians place orders within these systems instead of using traditional handwritten
transcription onto paper. These systems provide major safeguards by ensuring that physician
orders are legible and complete, thereby providing a level of patient safety that was historically
missing with paper-based orders. They provide decision support and automated alert
functionality that was previously unavailable with paper-based orders.
Computer science
The "systematic study of algorithmic methods for representing and transforming information,
including their theory, design, implementation, application, and efficiency.... The roots of
computer science extend deeply into mathematics and engineering. Mathematics imparts
analysis to the field; engineering imparts design" (University at Buffalo School of Engineering
and Applied Sciences;
Needs Assessment
An assessment of needs of a department or organization using different methods such as
surveys, interviews and report gathering.
