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 AHRQ, Effectiveness, NCQA, NQF

HHA   -   Home Health Agency.   See Long Term Care, SNF

HHS   -   United States Department of Health and Human Services is the cabinet level agency assigned to protect the health of all Americans and to provide human services. Major operating units within HHS with regard to health informatics include: AHRQ, CDC, CMS, FDA, HRSA, IHS, and NIH.   See AHRQ, CDC, CMS, FDA, HRSA, IHS, NCVHS, NIH, OIG, ONC

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 CHeQ, HIO, HRE, LHII, NAHIT, ONC, RHIO, Supply Chain

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 Ancestor, Child, Concept, Descendant, Parent, Relationship, Taxonomy, Terminology

HIMSS   -   Healthcare Information and Management Systems Society   See AHIMA, CCR, CHIME, EHRA

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 HIE, HRE, LHII, RHIO

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 Consent, Data Element, NCVHS, PHI, PII, Unsecured PHI

HIPPP   -   Health Informatics Public Private Partnership.   See OpenHIE

HIS   -   Hospital Information System, typically used for patient registration, admission, transfer and discharge, as well as billing and sometimes also laboratory, imaging, and pharmacy functions.   See EHR, RPMS, VistA

HISB   -   The Health Informatics Standards Board was formed by ANSI in 1996 and was replaced by HITSP in 2005.   See ANSI, HITSP, SDO

HISP   -   Health Information Service Provider.   See NHIN Direct

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.   See CalPSAB

HIT   -   Health IT.   See IT

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 ARRA, CEHRT, EH, EP, Meaningful Use, REC

HITPC   -   The Healthcare Information Technology Policy Committee, established by the HITECH Act, is charged with making recommendations to the National Coordinator for Health IT on standards, implementation specifications, and certification criteria for the electronic exchange and use of health information.   See FACA, HHS, HITECH, HITSC, ONC

HITSC   -   The Healthcare Information Technology Standards Committee, established by the HITECH Act, is charged with making recommendations to the National Coordinator for Health IT on a policy framework for the development and adoption of a nationwide health information infrastructure, including standards for the exchange of patient medical information.   See FACA, HHS, HITECH, HITPC, ONC

HITSP   -   ("hits-pea")   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 ANSI, HHS, HISB, ONC

HL7   -   Health Level 7, an accredited Standards Developing Organization (SDO) operating in the healthcare arena.   See ADT, ANSI, CCD, CDA, CVX, DEEDS, FHIR, ISO, MDM, MFN, MSH, MVX, NTE, OBR, OBX, OMG, ORM, ORU, PID, PV1, QBP, RIM, RXA, SDO, VXU, Z Segment

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 CSD, DSML, HITECH, HWR, IHE, IWG, LDAP, ModSpec, MU, PWP

HTML   -   HyperText Markup Language is a text and image formatting computer language designed for the creation of content containing hypertext links in an Internet environment. HTML was defined by Sir Tim Berners-Lee at CERN in 1990, giving rise to browsers and the World Wide Web.   See CERN, DHTML, DOM, Hypertext, W3C, WWW

HTTP   -   HyperText Transfer Protocol, an application layer method to transfer information on the World Wide Web, is defined by RFC 2616. HTTP is a stateless protocol   See CRUD, HTTPS, Protocol, REST, RFC, Stateless Protocol

HTTPS   -   Not a formal protocol itself, HTTPS refers to a normal HTTP interaction conducted via an encrypted and secure transport layer, such as SSL.   See SSL

Hyperlink   -   A clickable link (typically a word, or a phrase, or an image) that a user selects (e.g., with a mouse) to access an alternate web page or document.   See HTML, Linkrot

Hypertext   -   A term coined by Ted Nelson in 1965, referring to earlier work by Vannevar Bush. Hypertext links infuse information with an intuitive but nonlinear branching structure.
