Accreditation - Voluntary certification conferred by a professional organization, such as NCQA or TJC. See NCQA, TJC

ACK - A response flag in TCP to acknowledge receipt of a packet. The term is also used generically in other data networking contexts to acknowledge receipt of a message or a handshake, including HL7. See TCP

Aggregated Data - A set of data compiled for activities such as Public Health or clinical research. Aggregated data sets are typically intended to be unidentifiable at the level of an individual person, however the recent appearance of massively popular social networking sites on the internet has been shown to enable reidentification of individuals in data sets previously assumed to be de-identified. See De-identified_Data, Re-identified_Data

Ajax - Acronym for a combination of technologies, classic Ajax includes asynchronous JavaScript and XML. See JavaScript, REST, XML

Algorithm - A method of problem solving in which instructions are followed in a (usually) specific sequence. Algorithms may involve numeric calculation. See Care Pathway, Expert System, Guideline, Inference Engine, Protocol

AMA - American Medical Association See CPT

Ambulatory Care - A health care consultation delivered on an outpatient basis. See Acute Care, Inpatient, Patient, Outpatient

AMIA - American Medical Informatics Association, a national member society of IMIA. See IMIA, Informatics

Analytics - See BI

Anonymize - A filtering process intended to transform data into a format which does not allow determination of the specific identity to whom the data refers. See De-identified Data

ANSI - [ ANN-sea ] The American National Standards Institute is the U.S. member body to the ISO. ANSI does not write standards; rather the Institute accredits standards developers that will establish consensus among qualified groups. See HITSP, ISO

Audit Log - Record created by hardware (servers, routers, firewalls, etc.) or software (data bases, network systems, individual applications, etc.) that track when data are created, modified, transmitted or destroyed, including the identity of the user initiating the action.

Authentication - The physical or process method or methods employed to prove that the person or entity seeking access to information has the proper authorization. Generally used to protect confidential information by limiting system access to authorized users. Passwords are an example of a commonly employed authentication process.
