The active field of each component version indicates whether a component is active or inactive. However, it does not provide any information about why a concept or description has been inactivated. The reason why a concept or description has been inactivated is indicated by a row in a component Inactivation reference set. The reason for inactivation may determine the appropriate way to deal with data in existing records, protocols or queries that use a concept or description after it has been inactivated.
The two component inactivation Reference Sets are shown in Table 5.2.3.1-1.
Table 5.2.3.1-1: Component Inactivation Reference Sets
Reference Set Id and Name | Note |
|---|---|
Indicates the reason that a concept has been made inactive. | |
Indicates the reason that a description has been made inactive. |
The reason for inactivation is specified by a concept enumeration. The permitted values for this enumeration for a concept are shown in Table 5.2.3.1-2 and the permitted values for a description are shown in Table 5.2.3.1-3.
Table 5.2.3.1-2: Concept Inactivation Values
Concept Id and Term | Description | Example |
|---|---|---|
The concept has been made inactive because it has the same meaning as another concept. | The concept 727599004 | Entire thyroglossal tract (body structure)| was inactivated because it is a duplicate of 705323017 | Entire thyroglossal duct (body structure)| . | |
The concept has been made inactive because it is an outdated concept that is no longer used. | The concept 1192004 | Familial amyloid neuropathy, Finnish type (disorder)| had an out of date or inappropriate fully specified name. It was replaced by the concept 3757892013 | Hereditary gelsolin amyloidosis (disorder)| . | |
The concept has been made inactive because it is inherently ambiguous either because of an incomplete fully specified name or because it has several associated terms that are not regarded as synonymous or partial synonymous. | The concept 6835002 | Fetal OR neonatal jaundice from bruising (disorder)| was inactivated because it could mean either 591937013 | Perinatal jaundice from bruising (disorder)| or 1461890018 | Neonatal jaundice (disorder)| . | |
The concept has been made inactive because it contains an error. | The concept 727599004 | Entire thyroglossal tract (body structure)| was inactivated because is an NEC classification category which had previously been stated to be a subtype of 626562014 | Hypoadrenalism (disorder)| . | |
The concept is of limited value as it contains classification categories such as 'Not Elsewhere Classified', which do not have a semantically stable meaning. Until 2010 concepts with this status were regarded as active but since then they have been marked as inactive and should no longer be used. | The concept 42318001 | Other adrenal hypofunction, NEC (disorder)| was inactivated because it is a duplicate of 705323017 | Entire thyroglossal duct (body structure)| . | |
The concept was moved to another namespace or module. | The concept 417293005 | Laryngeal tie-forward (procedure)| was inactivated and moved to namespace 1000009 (the Veterinary Terminology Service Laboratory, USA) as it is procedure applied to horses. | |
The concept is still active but it is in the process of being moved to another namespace or module. When the move is complete it will be marked as inactive. | The concept 727599004 | Entire thyroglossal tract (body structure)| was inactivated because it is a duplicate of 705323017 | Entire thyroglossal duct (body structure)| . |
Table 5.2.3.1-3: Description Inactivation Values
Id | Term | Description | Example |
|---|---|---|
The description does not represent the same meaning as the concept's Fully Specified Name (FSN). This value was introduced in 2017-07-31. | The FSN Removal of device (procedure) has the synonym, Replacement of prosthetic device (procedure). The synonym has a more specific meaning than the FSN, so it should be inactivated (see Synonym in the SNOMED CT Editorial Guide) | |
A description fails to comply with the current editorial guidance. This value was introduced in 2017-07-31. | Prior to 2017-07-31, the concept 167238004 |Turbid urine (finding)| had the fully specified name "Urine: turbid (finding)". This was inactivated and replaced by a new fully specified name "Turbid urine (finding)" because this use of the colon is contrary to editorial guidance (see Punctuation and Symbols in the SNOMED CT Editorial Guide). | |
A description is outdated and is no longer current, useful, appropriate or acceptable. | The synonym "Funny looking kid" was inactivated from 112630007 |Abnormal facies (finding)| as it is not considered an appropriate term to use. | |
The description has been made inactive because it contains an error. | Case significance changes (e.g. "Alpha" where the initial letter should be a lower case "a"). Spelling errors (e.g. a description where "Asthma" is misspelled "Assthma"). | |
The description is still active but the concept it refers to is now inactive. | A concept that has been made inactive, still has active descriptions to allow the inactive concept to be displayed with a valid term. These descriptions are marked with this inactivation value. | |
| The following values used in earlier releases are no longer used in the International Release | ||
The description has been made inactive because it duplicates another description. Do not apply to current or future description inactivations This value has not been used in the International Release since 2017-07-31. | ||
The description refers to a concept that has limited status. Do not apply to current or future description inactivations This value has not been used in the International Release since 2017-07-31. | ||
The description has been made inactive because the associated term is does not describe the associated concept. Do not apply to current or future description inactivations This value has not been used in the International Release since 2017-07-31. | ||
| The following values related to transfer or responsibility for description are no longer used in the International Release | ||
The description was moved to another namespace or module. Do not apply to current or future description Do not apply to International Release description inactivations This value has not been used in the International Release since 2017-07-31. However, it may continue to be used in extensions. | ||
The description is still active but it is in the process of being moved to another namespace or module. When the move is complete it will be marked as Inactive. Do not apply to International Release description inactivations The value has never been using the International Release. However, it may be used in extensions. | ||
