Telehealth ÇÇA broad term having to do with providing health care services from a
distance. A direct service provided from a distance to clients/patients, consultations to other
health care professionals, education related to health care to clients or other health care
professionals, and coordination of care (helping integrated physical and behavioral health
concerns to improve the outcomes for both, reducing unnecessary readmissions, reducing
medication errors, treatment errors, wrong diagnosis).
Telemental health ÇÇProviding psychotherapy directly to a client when the clinician and the
client are not in the same location. Telemental health and mental health services are not
separate services. It is the same service, provided by different means.
Accountable Care Organization (ACO) ÇÇA healthcare organization characterized by a
payment and care delivery model that seeks to tie provider reimbursements to quality metrics
and reductions in the total cost of care for an assigned population of patients. (Wikipedia)
Analog ÇÇA continuous signal where the time varying variable is represented by another
time varying quantity. It differs from a digital signal where a continuous quantity is represented
by a discrete function that only takes on one of a finite number of values.
Application Service Provider (ASP) ÇÇAn ASP hosts a variety of applications on a central
server. For a fee, customers can access the applications over secure Internet connections or a
private network. This means that they do not need to purchase, install or maintain the software
themselves; instead they rent the applications they need from the ASP. New releases, such as
software upgrades, are generally included in the price.
,Asynchronous ÇÇTerm describing store and forward transmission of medical images and/or
data because the data transfer takes place over a period of time, and typically in separate time
frames. The transmission typically does not take place simultaneously. This is the opposite of
synchronous (see below).
Asynchronous Transfer Mode (ATM) ÇÇA telecommunications standard to support voice,
video and data communications. The mode uses asynchronous time-division multiplexing and
encodes data into small, fixed-sized cells rather than packets or frames.
Authentication ÇÇA method of verifying the identity of a person sending or receiving
information using passwords, keys and other automated identifiers.
Bandwidth ÇÇA measure of the information carrying capacity of a communications channel;
a practical limit to the size, cost, and capability of a telemedicine service.
Basic Rate Interface ÇÇAn ISDN (see below) configuration that provides two bearer (B)
channels at 64 kilobits/second (kbit/s) each and one data (D) channel at 16 kbit/s. B channels
are for voice data and D channels for any combination of data, control/signaling, and X.25
packet networking. B channels can be aggregated to provide128 kbit/s.
Bits Per Second (bps) ÇÇNumber of electronic data bits conveyed or processed per unit of
time.
,Bluetooth Wireless ÇÇAn industrial specification for wireless personal area networks (PANs)
that provides the means to connect and exchange information between devices such as mobile
phones, laptops, PCs, printers, digital cameras and video game consoles over a secure, globally
unlicensed short-range radio frequency. The specifications are developed and licensed by the
Bluetooth Special Interest Group (http://www.bluetooth.com/Pages/about-bluetooth-sig.aspx).
Bridge ÇÇDevice for linking multiple videoconferencing sites in a single videoconference
session. It is also often referred to as a multipoint control unit (MCU).
Broadband ÇÇCommunications (e.g., broadcast television, microwave, and satellite)
capable of carrying a wide range of frequencies; refers to transmission of signals in a frequency-
modulated fashion over a segment of the total bandwidth available, thereby permitting
simultaneous transmission of several messages.
Cascading ÇÇMeans to accommodate more videoconference participants than using one
MCU by joining another MCU into a session hosted by the primary MCU.
Certification Commission for Health Information Technology (CCHIT) ÇÇFounded in 2004
with the public mission of accelerating the adoption of health IT, it certifies electronic health
records (EHRs) using comprehensive, practical definitions of what capabilities were needed in
these systems. (http://www.cchit.org/)
Centers for Medicare & Medicaid Services (CMS) ÇÇA federal agency within the United
States Department of Health and Human Services (DHHS) that administers the Medicare
program and works in partnership with state governments to administer Medicaid, the State
, Children's Health Insurance Program (SCHIP), and Health Insurance Portability and
Accountability Act (HIPAA) standards. (Wikipedia)
Channel Service Unit/Data Service Unit (CSU/DSU) ÇÇA digital-interface device for
connecting Data Terminal Equipment devices (DTE) (e.g., router) to a digital circuit (e.g., T1
line). CSU connects to the network and the DSU handles the DTE interface.
Circuit Switched Network ÇÇA method for implementing a telecommunications network
where two nodes have a dedicated communications channel through the network for
communication, guaranteeing full bandwidth for the session.
Class of Service (CoS) ÇÇUsed in data and voice protocols to differentiate payloads in the
transmitted packets to help assign priorities to the data payload.
Clinical Decision Support System (CCDS) ÇÇSystems (usually electronically based and
interactive) that provide clinicians, staff, patients, and other individuals with knowledge and
person-specific information, intelligently filtered and presented at appropriate times, to
enhance health and health care.

Clinical Information System ÇÇHospital-based information system designed to collect and
organize data relating exclusively to information regarding the care of a patient rather than
administrative data. .
