EARS   -   Early Aberration Reporting System.   See Biosurveillance, CDC

ECG   -   Electrocardiography (ECG or EKG) is a noninvasive transthoracic interpretation of the electrical activity of the heart over time captured and externally recorded by skin electrodes. Not to be confused with an Echocardiogram.   See Echocardiogram

Echocardiogram   -   An echocardiogram, often referred to as a cardiac ECHO or simply an ECHO, is a sonogram of the heart. It is not abbreviated as ECG, which usually refers to an electrocardiogram. Also known as a cardiac ultrasound.   See Cardiac ECHO, ECG, Sonogram

ED   -   Emergency Department.   See DEEDS

EDI   -   Electronic Data Interchange (EDI) is computer to computer exchange of strictly formatted electronic data. EDI emerged from concepts and methods developed by military logistics to manage vast quantities of data about supplies in transport to support the Berlin Airlift. The first generation of commercial EDI standards were developed in the 1970s in the automotive industry to support procurement and supply chain logistics between trading partners. Content and transport standards were adopted or developed by ad hoc EDI specifications among high volume trading partners in various industries. The emergence of the Internet enabled further optimization of EDI standards (e.g., RFC 3335, RFC 4130, etc.).   See MRP, RFC, Supply Chain

EFF   -   Electronic Frontier Foundation.   See DRM

Effectiveness   -   How well a health care treatment works in practice.   See AHRQ, Efficacy, HEDIS, NCQA, NQF

Efficacy   -   How well a health care treatment works in clinical trials.   See Effectiveness

e-Health Initiative   -   See eHI

EH   -   Eligible Hospital, referring specifically to eligibility for access to incentive funds appropriated by HITECH and dispersed by State and Federal agencies pursuant to the rules promulgated for the Meaningful Use of CEHRT.   See CEHRT, EP, HITECH, MU

eHealth Exchange   -   See Healtheway

eHI   -   The e-Health Initiative is a neutral, multi-stakeholder organization that helps connect the dots in healthcare and technology. eHealth Initiative's mission is to drive improvement in the quality, safety, and efficiency of healthcare through information and technology.   See CCBH

EHR   -   Electronic Health Record, a generic term for computerized records in health care. There is terminology ambiguity of EHR with the similar term Electronic Medical Records. In general, Redwood MedNet uses EHR as the more inclusive term.   See CEHRT, CPOE, EMR, RPMS, Template, VistA

EHRA   -   The Electronic Health Record Association is a trade association of EHR vendors sponsored by HIMSS. EHRA addresses national efforts to create interoperable EHRs in hospital and ambulatory care settings.   See HIMSS

eICU   -   ICU with clinical staffing augmented by remote presence telehealth services.   See ICU, Remote Presence

EIN   -   Employer Identification Number.

EIS   -   Entity Identification Service, part of the HSSP.   See HSSP, MPI

EKCITA   -   East Kern County Information Technology Association, awarded an HIE Expansion Grant in 2011 by Cal eConnect. Renamed CVCAHIE in 2012.   See Cal eConnect

EKG   -   See ECG

ELINCS   -   The EHR Lab Interoperability and Connectivity Standard is a magnificent multiyear effort by California HealthCare Foundation to reduce optionality, and therefore to increase interoperability and utility, in HL7 messaging formats for the content of laboratory test results. Field adoption of the ELINCS format, an HL7 v.2.5.1 standard, has yet to be sufficiently robust to achieve the desired effect, therefore the original intent of standardizing and commodifying structured laboratory test result data to optimize interoperability remains an urgent informatics challenge.   See CHCF, HL7

ELR   -   Electronic Laboratory Reporting, a specialized term from the public health sector.   See CMR

Email   -   Short for electronic mail, a method of exchanging digital messages, generally via the Internet.   See SMTP

EMAR   -   Electronic Medication Administration Record, sometimes written eMAR. Inpatient medication record keeping system designed to support the five rights of medication (right patient, right medication, right dose, right time, right route of administration).   See CPOE, eRx

EMPI   -   Enterprise Master Person Index. Sometimes written as "eMPI".   See MPI

EMR   -   Electronic Medical Record, a generic term for computerized records in health care. Conflicting definitions are associated with this term.   See EHR, CPOE

EMS   -   Emergency Medical Services.

EMT   -   Emergency Medical Technician.

Encryption   -   The process of transforming information to make it unreadable, thereby protecting the data while it is in transport or storage. For later use the information is decrypted (i.e., returned to an unencrypted state).   See Access Control, Authentication, Decryption, PKI, X.509

Enterprise Service Bus   -   See ESB

EO   -   Executive Order. United States Presidents issue executive orders to help officers and agencies of the executive branch manage the operations within the federal government itself. Executive orders have the full force of law when they take authority from a power granted directly to the Executive by the Constitution, or are made in pursuance of Acts of Congress that explicitly delegate to the President some degree of discretionary power (delegated legislation). Like statutes or regulations promulgated by government agencies, executive orders are subject to judicial review, and may be struck down if deemed by the courts to be unsupported by statute or the Constitution. In 2004 an EO by President Bush established the ONC within HHS. Later the HITECH act created an explicit statutory basis from Congress for the ONC.   See HHS, HITECH, ONC

EP   -   Eligible Provider, referring to eligibility for access to incentive funds appropriated by HITECH and dispersed by State and Federal agencies pursuant to the rules promulgated for the Meaningful Use (MU) of CEHRT.   See CEHRT, EH, HITECH, MU

EPA   -   Environmental Protection Agency.

e-Prescribing   -   Electronic prescribing is a health IT solution that allows a provider to review medication history and formulary coverage, and to originate a prescription electronically.   See EMAR

ERP   -   Enterprise Resource Planning (ERP) can be thought of as MRP-III, extending integrated and real-time business process coordination to non-manufacturing services within the enterprise. CRM as a component system is a typical example of the expansive ERP purview.   See CRM, MRP, MRP-II, Supply Chain

eRx   -   See e-Prescribing

Error   -   Generally, a synonym for mistake, with variable meanings in a wide range of settings (e.g., an error in baseball, a typographical error in a printed manuscript, computing the wrong numeric answer in mathematics, etc.). In medicine or in health informatics, when considering a hypothesis as true or false, there are two types of error: Type I (a false positive) or Type II (a false negative).   See Type I Error, Type II Error

ESB   -   Enterprise Service Bus is a software architecture that allows design and implementation of mutually interacting software SOA applications.   See SOA

ESSENCE   -   See Biosurveillance, CDC

Ethernet   -   Common name for the IEEE 802.3 network data standards that specify frame based wiring and signaling protocols combined with a common packet addressing format. Ethernet is the common LAN protocol of the Internet era. Ethernet was invented in 1973 at Xerox PARC as a "multipoint data communication system with collision detection."   See IEEE, LAN, PARC

Evidence Based Medicine   -   The practice of medicine according to clinical guidelines developed to reflect best practices captured from analysis of the peer reviewed clinical literature   See Best Practice, Guideline

Executable   -   In computing an executable file is a program that instructs a computer to perform tasks based on specific instructions, as opposed to a data file that must be parsed by a computer program to be meaningful. Executable instructions are typically machine code instructions for a physical CPU, but other formats exist.   See Compiler, Computer Language, Computer Program, CPU, Source Code

Executive Order   -   See EO

Expert System   -   Software that seeks to answer a question. An expert system is built in a specific problem domain by creating a data base that seeks to capture and formally represent knowledge drawn from subject matter experts (SME) in that problem domain.   See Algorithm, Guideline, Inference Engine, Knowledge Base, Protocol
