EncompassingEncounter Tabular View

EncompassingEncounter

In most but not all cases the Encompassing Encounter template covers an episode of care.

An episode of care for the purpose of this specification is defined as:-

A continuous period of care (including assessment for care) for a person for an illness or condition involving health and possibly other agencies which has been nationally targeted and prioritised as requiring an organised and cohesive programme or regime of care. Overall management and coordination of the care will be the solely led responsibility of a specific Health Care Provider, or in the case of equally shared responsibility, the jointly led responsibility of two or more Health Care Providers. Actual treatment associated with the programme or regime of care may be delivered by the responsible Health Care Provider or by other Health Care Providers.

This class represents the setting of the clinical encounter during which the documented act(s) or service event occurred. Documents are not necessarily generated during an encounter, such as when a clinician, in response to an abnormal lab result, attempts to contact the patient but can't, and writes a progress note.

In some cases, the setting of the encounter is inherent in the ClinicalDocument.code, such as where ClinicalDocument.code is "Diabetes Clinic Progress Note". The setting of an encounter can also be transmitted in the HealthCareFacility.code attribute. If HealthCareFacility.code is sent, it should be equivalent to or further specialize the value inherent in the ClinicalDocument.code. Such as where the ClinicalDocument.code is simply "Clinic Progress Note" and the value of HealthCareFacility.code is "cardiology clinic"). HealthCareFacility.code shall not conflict with the value inherent in the ClinicalDocument.code, as such a conflict would constitute an ambiguous situation.

The following notes are recommendations for the use of this template:

The same instance of an encompassing encounter can appear in multiple documents, document sets and documents types.

The id (UUID) has to be the same for it to be the same encounter

The information carried in the encounter should not be changed unless the id (UUID) is changed but more information may be added for example:

The start time in all instances must be the same (it may be missing in the early instances and added in later instances)

The end time in all instances must be the same (it may be missing in early instances and added in later instances)

The EncompassingEncounter code must be the same type in all instances but can be further refined ( consultation can be refined to telephone consultation for example)

The location cannot be changed but more information maybe added

Participants can be added but should not be removed, participant time should be used to indicate when the person's/organisations were involved

Responsible party can only be changed when the person or organisation responsible changes. A responsible organisation can be refined to be a named person within that organisation

The XML attribute displayName shall carry the description " NHS111 Encounter "

[1..1] [M] dischargeDispositionCode (CV { CWE:EncounterDispositionSnCT } )

Model Attribute Description

The HL7 attribute dischargeDispositionCode uses a code from any vocabulary to describe how the encompassing encounter ended. In the absence of any local vocabulary then a SNOMED CT code from the EncounterDispositionSnCT vocabulary can be used to describe how the encompassing encounter ended.

Implementation in XML Instance

For NHS 111 this will be the final disposition code reached after the patient triage.

When using a SNOMED CT code then:

The Coded Plain flavour of Coded Value (CV) data type shall be used to carry this information in the XML element code as follows:

The XML attribute code shall contain a code from the subset stated in EncounterDispositionSnCT vocabulary
The XML attribute codeSystem shall contain the OID " 2.16.840.1.113883.2.1.3.2.4.15 "
The XML attribute displayName shall carry a description associated with the code in the subset stated in the EncounterDispositionSnCT vocabulary. It is recommended that the preferred term is used to populate this attribute
The XML attribute originalText may be used if required to carry the text or phrase used as the basis for the coding

The use of the SNOMED CT terms in this subset are for guidance purposes only.Codes outside this subset may be used at clinical discretion.

When using an alternative vocabulary and an OID is available then:

The Coded Plain flavour of Coded Value (CV) data type shall be used to carry this information in the XML element code as follows:

The XML attribute code shall contain a code from the alternative vocabulary
The XML attribute codeSystem shall contain the OID for the alternative vocabulary
The XML attribute displayName shall carry a description associated with the code
The XML attribute originalText may be used if required to carry the text or phrase used as the basis for the coding

The Coded Plain flavour of Coded Value (CV) data type shall be used to carry this information in the XML element code as follows:

The XML attribute code shall contain a code from the alternative vocabulary
The XML attribute codeSystem shall contain the OID " 2.16.840.1.113883.2.1.3.2.4.17.414 "
The XML attribute displayName shall carry a description associated with the code
The XML attribute originalText may be used if required to carry the text or phrase used as the basis for the coding

[1..1] [M] effectiveTime (IVL<TS>)

Model Attribute Description

The HL7 attribute effectiveTime uses low (start), high (end) and center (point in time) to detail time associated with / relevant to the encounter.

Implementation in XML Instance

The XML attribute value of the XML elements low, center and high, shall be populated (when used in the instance) with a time stamp in the format yyyymmddhhmmss[+|-ZZzz] where:

yyyy is the year
mm is the month
dd is the day
hh is the hour
mm is the minute
ss is the seconds
[+|-ZZzz] is the time zone offset in hours and minutes

Sections from the right of this representation may be left off when the sending system does not record to this level of accuracy. When hours are present, the time zone offset must also be present.

For NHS 111

The XML attribute value of the XML element low shall be used to indicate start of the NHS 111 encounter
The XML attribute value of the XML element high shall be used to indicate the end of the NHS 111 encounter, if available. If the end time of the encounter is not known, high should be omitted.
