Authentication - Verifying the identity of a user, process, or device before allowing access to resources in an information system

Computerized Provider Order Entry (CPOE) – A computer application that allows a physician’s orders for diagnostic and treatment services (such as medications, laboratory, and other tests) to be entered electronically instead of being recorded on order sheets or prescription pads. The computer compares the order against standards for dosing, checks for allergies or interactions with other medications, and warns the physician about potential problems.

Decision-Support System (DSS) - Computer tools or applications to assist physicians in clinical decisions by providing evidence-based knowledge in the context of patient specific data. Examples include drug interaction alerts at the time medication is prescribed and reminders for specific guideline-based interventions during the care of patients with chronic disease. Information should be presented in a patient-centric view of individual care and also in a population or aggregate view to support population management and quality improvement.

De-identified Health Information - Removal of name, address, and other personal information when sharing health information so that it cannot be used to determine who a person is.

Electronic Health Record (EHR) – A record of health-related information for an individual that is in electronic format and conforms to nationally recognized standards that can be accessed and updated across one or more health care organizations.

Electronic Medical Record (EMR) - A real-time patient health record with access to evidence-based decision support tools that can be used to aid clinicians in decision-making; the EMR can automate and streamline a clinician’s workflow, ensuring that all clinical information is communicated; it can also prevent delays in response that result in gaps in care; the EMR can also support the collection of data for users other than clinical care, such as billing, quality management, and public health disease surveillance and reporting.

Electronic Prescribing (eRx) – A type of computer technology whereby physicians use handheld or personal computer devices to review drug and formulary coverage and to transmit prescriptions to a printer or to a local pharmacy. E-prescribing software can be integrated into existing clinical information systems to allow physician access to patient specific information to screen for drug interactions and allergies.

Encryption - The translation of information to a code to keep it secret.
Health Information - Any information, whether oral or recorded in any form or medium, that is created or received by a health care provider, health plan, public health authority, employer, life insurer, school, or university and relates to the past, present or future physical or mental health or condition of an individual; the provision of health care to an individual; or the past, present or future payment for the provision of health care to an individual.

Health Information Exchange (HIE) - The electronic movement of health-related information among organizations according to nationally recognized standards.

Health Information Technology (HIT) – The application of information processing involving both computer hardware and software that deals with the storage, retrieval, sharing, and use of health care information, data, and knowledge for communication and decision making.

Health Insurance Portability and Accountability Act (HIPAA) - The law Congress passed in 1996 that requires that health information be kept private.

Interoperability - The ability of systems or components to exchange health information and to use the information that has been exchanged accurately, securely, and verifiably, when and where needed.

Master Patient Index (MPI) - A list of all known patients in an area, activity, or organization.

Meaningful Use (MU) - The American Recovery and Reinvestment Act authorizes the Centers for Medicare and Medicaid services (CMS) to provide a reimbursement incentive for physicians and hospital providers who are successful in becoming “meaningful users” of an electronic health record (EHR).

National Health Information Network (NHIN) - An interoperable, network based on standards that is across the nation and enables the secure exchange of health information.

Personal Health Record (PHR) – An electronic application through which individuals can maintain and manage their health information (and that of others for whom they are authorized) in a private, secure, and confidential environment.

Protected Health Information - Health Information transmitted or maintained in any form that can reasonably be used to identify an individual.
