Coding common clinical language in SNOMED CT and ICD-10-CM_SIADs_Thierry Klein.xlsx

A homogeneous corpus with a focus on systemic inflammatory and autoimmunedisorders (SIADs) . An internist, head of the department of internal medicine in an academic hospital,has encoded on-line medical history elements (MHE) in a self-made software application for thirty years. A total of 13130 clinical MHEs has been collected. This corpus is totally homogeneous, on-line entered by a single user. We have extracted from this corpus the most frequent SIADs mentioned in the MHE.In a first step, a gold standard reference has been built. We manually coded the clinical phrases in SNOMED CT expressions following the postcoordination technique. We extracted then systematically the SNOMED CT precoordinated codes and we finally applied the SNOMED CT to ICD-10-CM mapping. In the second step, a Natural Language Processing software (NLP) annotated the clinical text phrases in SNOMED CT and ICD10-CM. <br><br>
