Immune Thrombocytopenic Purpura, Diagnosed

This concept set contains concept codes for immune thrombocytopenic purpura (itp). This was developed as part of autoimmune/chronic conditions for a RECOVER study manuscript exploring features of children with PASC. The code list was generated by searching for all descendants of the SNOMED code 234490009 (Immune thrombocytopenic purpura) plus all ICD10 or ICD10CM codes mapping to those SNOMED descendants. String matching was also performed looking for the string ("immune" or "idiopathic") and "thrombocytopeni" and "purpura" in the condition domain and excluding the term "family history". The concept set was limited to ICD10, ICD10CM, and SNOMED vocabularies.

本概念集收录免疫性血小板减少性紫癜（immune thrombocytopenic purpura，ITP）的相关概念编码。本概念集作为自身免疫性/慢性疾病类别的组成部分，由一项旨在探究儿童PASC患者临床特征的RECOVER研究手稿开发而成。该编码列表通过检索SNOMED（系统医学命名法）编码234490009（免疫性血小板减少性紫癜）的所有下位概念，以及映射至这些SNOMED下位概念的全部ICD-10（International Classification of Diseases 10th Revision）与ICD-10-CM（International Classification of Diseases 10th Revision Clinical Modification）编码生成。同时通过字符串匹配法，在疾病领域术语中检索同时包含“immune”或“idiopathic”、“thrombocytopeni”与“purpura”的条目，并排除含“family history”字样的内容。本概念集仅限定使用ICD-10、ICD-10-CM及SNOMED三类术语词汇表。
