ARCHETYPE Tos Classification (openEHR-EHR-CLUSTER.tos.v0)

ARCHETYPE IDopenEHR-EHR-CLUSTER.tos.v0
ConceptTos Classification
DescriptionA classification of the degree of tympanic membrane pars flaccida retraction, related to extent and severity and as described by Tos and Poulsen.
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 Tos Classification to allow recording of Tos Grade 5 which 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 attic retraction of the tympanic membrane, based on the classification by Tos and Poulsen.
