Description of the addition or change
78667006 | Dysthymia (disorder) | active descriptions include Dysthymia Depressive neurosis Neurasthenic neurosis Neurasthenia Nervous debility Neurotic depression Nervous breakdown UMLS identifies five distinct concepts here... C0011581 Depressive disorder C0013415 Dysthymic Disorder C0027804 Neurasthenia C0221508 Nervous breakdown C0282126 Depression, Neurotic See http://www.diseasesdatabase.com/snomed/78667006 Likewise CTV3 antecedents of 78667006 | Dysthymia (disorder) | are several distinct concepts http://www.diseasesdatabase.com/snomed/snomed_maps.asp?id=78667006 While several (even all) of these descriptions are outmoded the conflations are nonetheless major. These groups of terms are not (were not) even closely related! These terms are in use in medical records and this conflated concept is causing issues for reporting and decision support in the application I am working on. I suggest this concept be inactivated as ambiguous. Perhaps consider reversing the SNOMED historical changes http://www.diseasesdatabase.com/snomed/historical_associations.asp?id=78667006 Thank you for taking a look at this.
