ARCHETYPE Sade Classification (openEHR-EHR-CLUSTER.sade.v0)

ARCHETYPE IDopenEHR-EHR-CLUSTER.sade.v0
ConceptSade Classification
DescriptionGrading of the degree of tympanic membrane pars tensa retraction / atelectasis.
UseUse to record the grading of tympanic membrane retraction, particularly by specialist physicians. Designed to be optionally nested within the CLUSTER.exam_tympanic_membrane archetype to provide additional detail on tympanic membrane retraction, if it is useful within a given clinical scenario. This archetype extends the Sade Classification to allow recording of 'No visible retraction' where applicable. Sade Stage 5 (spontaneous perforation) is described in some documentation but is not described in the original paper and appears not to be in common usage.
PurposeTo record the grading of tympanic membrane pars tensa retraction based on the classification by Sade.
