#### Access Control Framework (ACF)

Access to NHS Care Records Service data (on Spine) is controlled by the ACF which registers and authenticates all users. It provides a single log-in and a record of each healthcare professional accessing a patient's NHS care record. All information is provided on a need-to-know basis and based on a user's role and legitimate relationship; with the patient. It stores the details of those relationships between healthcare professionals and patients, as well as patient preferences on information sharing (e.g. whether certain sensitive information is restricted from routine sharing).

The NHS is only able to see that a child or foetus has a Child Protection Plan or is in the Looked After system. The information provided is start, end and delete dates; plus a Children's Services contact telephone number where the NHS can get further information. Basic information about NHS accesses is also passed back to Children's Services.

The main difference between this and a Message Implementation Manual (MIM), is that the MIM will contain a variety of domains with their business analysis artefacts included.

#### Electronic Healthcare Record (EHR)

This is the concept of electronic longitudinal collection of patient's health and health care from cradle to grave. It combines information from different care settings held in different systems and in some instances aggregates the data and shows them as a single record. It is a record in digital format that is capable of being shared across different health care settings, by being embedded in network-connected enterprise-wide information systems.

#### Message Implementation Manual (MIM)

The MIM provided information to implementers regarding the use of HL7 v3 messages within the English NHS. Messages and Data Types are based on the HL7 v3 Reference Information Model and realm specific constraints were applied where appropriate and were identified within the documentation. The MIM has been superseded by the Domain Message Specifications (DMS).

#### Participation

The involvement of a HL7 role class in an HL7 act class.

#### Patient Administration System (PAS)

Is a core component of a hospital computer system which records the patient's name, home address, date of birth and each contact with the outpatient department or admission and discharge. The NHS patient's record and appointment tracking system is often called PAS, depending on the NHS Hospital Trust. This computerised administration solution that assists with planning, tracking and recording the patient's contact with the outpatient department or admission and discharge.

#### Patient Demographic Service (PDS)

This is an essential element of the NHS Care Records Service which will underpin the creation of an electronic care record for every registered NHS patient in England. Each person's care record will be comprised of both demographic information, such as name, address, date of birth and NHS Number, and medical information.

#### Personal Spine Information Service (PSIS)

The central database on the Spine containing clinical records for each NHS patient.

#### Portable Network Graphics (PNG)

Is a bitmapped image format and video codec that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license.

#### Primary Care Trust (PCT)

Responsible for primary and community health services within a geographical boundary.

#### Provider

#### Reference Information Model (RIM)

This is the cornerstone of the HL7 Version 3 development process. An object model created as part of the Version 3 methodology, the RIM is a large, pictorial representation of the HL7 clinical data (domains) and identifies the life cycle that a message or groups of related messages will carry. It is a shared model between all domains and, as such, is the model from which all domains create their messages. The RIM is an American National Standards Institute (ANSI) approved standard.

#### Synonym (SY)

A synonym represents a term, other than the FSN or Preferred Term, that can be used to represent a concept in a particular language or dialect.

#### Systematized Nomenclature of Medicine Clinical Terminology (SNOMED CT)

This is a clinical terminology. It is a common computerised language to facilitate communications between healthcare professionals in clear and unambiguous terms. It has greater depth and coverage of healthcare than the versions of Clinical Terms (Read Codes) that it will replace and will enable clinicians, researchers and patients to share and exchange healthcare and clinical knowledge worldwide. SNOMED CT has been chosen to be the common language for gathering and sharing medical knowledge in the NHS Care Records Service. It will cut down the potential for differing interpretation of information and the possibility of errors resulting from traditional paper records.

#### Telecare

Telecare is a service that enables people, especially older and more vulnerable individuals, to live independently and securely in their own home. It includes services that incorporate personal and environmental sensors in the home, and remotely, that enable people to remain safe and independent in their own home for longer. 24 hour monitoring ensures that should an event occur, the information is acted upon immediately and the most appropriate response put in train.

#### Telehealth

Telehealth – often referred to as remote patient monitoring - refers to the use of various point-of-care technologies to monitor a patient’s physiological status and health conditions. When combined with personalised health education within a chronic disease management programme, it can significantly improve an individual’s health and quality of life. Typically, it involves electronic sensors or equipment that monitors vital health signs remotely from home or while on the move. Readings are automatically transmitted to an appropriately trained person who can monitor the health vital signs and make decisions about potential interventions in real time, without the patient needing to attend a clinic.

#### Template

A template is a HL7 Refined Message Information Model which is used to constrain another HL7 model.

#### Templated (instance format)

#### Transaction Messaging Service (TMS)

This is a message transfer service that allows clinical messages from NHS Care Records Service (NHS CRS) users to be securely routed to the service they are requesting and to manage the response to that request. Depending on the type of message (e.g. relating to Choose and Book or the Personal Demographics Service), the Transaction Messaging Service identifies where the message needs to be sent.

#### Transform (XSLT)

A language for transforming eXtensible Markup Language.

#### Unattended Messaging Session (UMS)

An "Unattended Messaging Session" is defined as when a system sends a message with no user intervention, and with no authenticated user session. Examples of this might be a Patient Administration System (PAS) requesting PDS retrievals as part of populating the day's patient list.

#### Uniform Resource Locator (URL)

Is a reference (an address) to a resource on the Internet. For example a URL could be the name of a file on the World Wide Web because most URLs refer to a file on some machine on the network. However, URLs also can point to other resources on the network, such as database queries and command output.

#### x_domain
