Information System
an automated system that uses computer hardware and software to record,
manipulate, store, recover, and disseminate data (that is, a system that receives and
processes input and provides output)
Financial applications
software applications that handle patient accounts, budgets, and other financial
activities
Mainframe computers
large computers that are used by the government and other organizations that
require speed and the ability to process large amounts of data.
Dumb Terminals
all of the processing is performed at the server or mainframe
Cloud Computing
a system that operates on a computer that is owned and maintained by a vendor.
Intranet
a private information network that uses Internet technologies; however, its servers
are located inside a firewall or security barrier so that the general public cannot gain
access to information housed within the network
Health Information Exchange
,the exchange of health information electronically between providers and others with
the same level of interoperability.
Evidence-based medicine
healthcare services based on clinical methods that have been thoroughly tested
through controlled, peer-reviewed biomedical studies
Clinical pathways
a tool designed to coordinate multidisciplinary care planning for specific diagnoses
and treatments
clinical practice guidelines
provide a detailed, step-by-step guide used by healthcare practitioners to make
knowledge-based decisions related to patient care and issued by an authoritative
organization such as a medical society.
Health Informatics
scientific discipline that is concerned with the cognitive, information-processing, and
communication tasks of healthcare practice, education, and research, including the
information science and technology to support these tasks
Data Analytics
the science of examining raw data with the purpose of drawing conclusions about
that information
Data mining
process of extracting and analyzing large volumes of data from a database for the
purpose of identifying hidden and sometimes subtle relationships or patterns and
using those relationships to predict behaviors.
, dashboards
reports of process measures to help leaders follow progress to assist with strategic
planning
descriptive statistics
set of statistical techniques used to describe data, such as means, frequency
distributions, and standard deviations; describes the characteristics of a specific
group or a population
inferential statistics
set of statistical techniques that allows researchers to make generalizations about a
population's characteristics on the basis of a sample's characteristics,
predictive modeling
process used to identify patterns that can be used to predict the odds of a particular
outcome based on the observed data. Uses historical data in order to predict what is
likely to happen in the future.
certified health data analyst (CHDA)
advanced certification covers data management, data analytics, and data reporting
Clinical Information Systems
collects and stores medical, nursing, clinical ancillary areas (such as radiology and
laboratory), and therapy department information related to patient care
document management system
electronic method of capturing and managing documents.
