HEDIS - The Healthcare Effectiveness
Data and Information Set (HEDIS) is a proxy for quality measures
designed by health insurance plans to provide health insurance purchasers
(i.e., primarily employers) with the ability to reliably compare the
cost effective performance of health plans. Based on billing data, and
formerly known as the Health Plan and Employer Data and Information Set,
the HEDIS measures are not to be confused with quality and effectiveness
measures derived from actual clinical data. See

the health of all Americans and to provide human services. Major
operating units within HHS with regard to health informatics
include: AHRQ,

HIE - Health
Information Exchange. Recently ONC sought to limit the use of HIE as
a verb-only term by adopting the cumbersome variant "HIO" as the
noun-only counterpart term. To date this effort seems to have insufficient
traction for broad field use, leading to terminology ambiguity (similar
to EMR vs. EHR). Based on current usage HIE is likely to survive as a
single multipurpose (noun + verb) term, and HIO having gained limited
use is likely to join "RHIO" and "LHII" as a deprecated terminology fork.
One confound is the launch of Health Insurance Exchanges (also HIE) in
2013. See

Hierarchy - A tree-like structure or layout that
groups concepts according to relationships. Hierarchies are found in Taxonomies
and Terminologies. Hierarchies are generally thought of as "growing" down, so
that Parents or Ancestors are spoken of as being "above" their corresponding
Children or Descendants. See

HIO - Health Information Organization. Introduced
by ONC as a formal noun-only counterpart term to HIE (which is, officially,
the "verb-only" term). Field adoption of the distinction between HIO vs. HIE
(i.e., noun vs. verb) is likely insufficient to displace general use of HIE as
both noun and verb. See

HIPAA - The Health Insurance Portability and
Accountability Act (HIPAA) was enacted by the U.S. Congress in 1996. HIPAA
protects health insurance coverage for workers and their families when they
change or lose their jobs. HIPAA requires the establishment of national
standards for electronic health care transactions and national identifiers
for providers, health insurance plans, and employers. HIPAA also addresses
the security and privacy of health data and defines Protected Health
Information (PHI). See

as billing and sometimes also laboratory, imaging, and pharmacy
functions. See

HISPC - ("hiss-pick") The
Healthcare
Information Security and Privacy Collaboration was a multi-disciplinary
partnership of government and private sector participants formed to assess
and develop plans to address variations in organization-level business
policies and state laws that affect privacy and security practices which
may pose challenges to interoperable health information exchange.

HITECH - A U.S. law passed in 2009,
whose full title is the Health
Information Technology for Economic and Clinical Health Act. The HITECH
Act is the health IT component of the larger ARRA legislation. HITECH
appropriated billions of dollars of economic recovery funds to be dispersed to
Eligible Hospitals and Eligible Providers who qualify for the funds based on
new rules invented to document the Meaningful Use of CEHRT. See

The
Healthcare Information Technology
Standards Panel, organized under ANSI, was created in 2005 under a
contract with the Office
of the National Coordinator (ONC). HITSP operated as a cooperative
partnership between the public and private sectors. The Panel was formed
for the purpose of harmonizing and integrating standards to meet clinical
and business needs for sharing information among organizations and
systems in healthcare. HITSP's contract with HHS
concluded
on April 30, 2010. See

HPD -
Healthcare Provider Directory (HPD) is an IHE specification that supports
management of healthcare provider information, both individual and
organizational, in a directory structure. HPD is the provider directory
service promoted by the HITECH Meaningful Use process, and is currently both
in live use in many regions and also undergoing evolution (HPD+,
IWG extensions, ModSpec revisions, etc.). HPD+ is based on LDAP with DSML. In
2011 - 2012 Redwood MedNet tested HPD services. Currently Redwood MedNet is
testing CSD as a successor to HPD. See

content containing hypertext links in an Internet environment. HTML was

Hypertext -
A term coined by Ted Nelson in 1965, referring to earlier work by Vannevar Bush.
