To evaluate the clinical completeness of the National Library of Medicine Metathesaurus(META), we coded the conceptual information found in 2000 problem oriented (SOAP) notes for hypertension from one COSTAR site. To minimize the effects of practice idiosyncracy, we analyzed an additional 500 notes from a second, geographically remote site. Concepts occurring at either site numbered 1337. We classified concepts occurring at both sites as core concepts and these numbered 121. We attempted to find a matching concept of the proper semantic type in META for each of the items. All matching was done by program with a manual review by a physician. The overall success rate for matching was: [table: see text] We observed the greatest frequency of unmatched concepts in physical examination, medications, symptoms, personal behavior, non-medical therapies and counselling. We conclude that the current release of META is not sufficiently rich to describe the process of care in the ambulatory management of hypertension. However, the construction and breadth of the current scheme holds promise for medical knowledge representation and translation.
为评估美国国立医学图书馆叙词表（META）的临床完整性，我们对来自一个COSTAR站点的2000份高血压问题导向型（SOAP）病历中的概念信息进行了编码。为尽量减少实践特殊性的影响，我们又分析了来自另一个地理位置较远站点的500份病历。两个站点出现的概念共有1337个。我们将在两个站点都出现的概念归类为核心概念，共有121个。我们试图为每个条目在META中找到语义类型合适的匹配概念。所有匹配均通过程序完成，并由一名医生进行人工审核。匹配的总体成功率为：[表格：见正文]我们观察到，在体格检查、药物治疗、症状、个人行为、非药物治疗和咨询方面，未匹配概念的出现频率最高。我们得出结论，当前版本的META不够丰富，无法描述高血压门诊管理中的护理过程。然而，当前方案的构建和广度为医学知识表示和转换带来了希望。
