**See comments added to previous meeting agenda page for more information* "Diastolic arterial pressure - please can you review current content regarding diastolic arterial pressure and add a new concept for Diastolic arterial pressure. There is a concept that is inactive. This would match 72313002|Systolic arterial pressure (observable entity)|, and thus provide the required Observable targets for all GP composite BP readings. There are currently two observable entity concepts for the recording of 271649006 | Systolic blood pressure (observable entity) and 72313002 | Systolic arterial pressure (observable entity) but the diastolic observable entity concept (271650006 | Diastolic blood pressure (observable entity)) has the synonym of 2620223019 | Diastolic arterial pressure. Please can you review this concept and add a new concept for Diastolic arterial pressure? Primary care composite BP readings (of which there are a few billion to be migrated...) are generally recorded against two READ2/CTV3 codes, one for the systolic and one for the diastolic element. These need mapping to SCT observables. The 'obvious' targets of 271649006|Systolic blood pressure (observable entity)| and 271650006|Diastolic blood pressure (observable entity)| are IMHO in fact inappropriate because they're groupers: they subsume, for example, the notions of target BP. This is potentially a problem in querying contexts; I'd rather move the 'random' BP readings further down the taxonomy. A suitable concept already exists under 271649006|Systolic blood pressure (observable entity)|, but the proposed solution requires the other half instating under 271650006|Diastolic blood pressure (observable entity)|. http://www.scielo.br/scielo.php?script=sci_arttext&pid=S2358-04292017000600005 https://www.ncbi.nlm.nih.gov/pubmed/18469640" I reviewed the Vital signs I/E document again ( https://confluence.ihtsdotools.org/x/bJW2AQ) and didn’t find this specifically addressed except the mention of the above description. Some questions I have: - Do we need a concept which is “Systolic arterial blood pressure at single point in time?” or “Random systolic arterial blood pressure?” (and equivalent diastolic arterial pressure)?
- Do we need to reactivate 67726005 |Diastolic arterial pressure (observable entity)|?
- Do we need to remove description “SAP - Systolic arterial pressure” from 271649006 |Systolic blood pressure (observable entity)|?
- What is intended relationship and difference between 271649006 |Systolic blood pressure (observable entity)| and 72313002 |Systolic arterial pressure (observable entity)|? Currently they are supertype-subtype.
