Over a period of 40 years, SNOMED has developed from a pathology-specific nomenclature (SNOP) into a logic-based health care terminology. In spite of its long existence and continuous evolvement, it is yet unknown to what extent SNOMED is used in clinical practice, and what benefits were achieved. The aim of this paper is to investigate this by providing an overview of published studies in which a version of SNOMED was studied or applied.
This paper analyzes the use of SNOMED over time, as reflected in scientific publications, by means of Medline literature search in PubMed. The search included papers from 1966 until June 2006. For each selected paper the following characteristics were classified: version, medical domain, coding moment (during or after the care process), usage, and type of evaluation (e.g., does SNOMED work, does SNOMED help).
250 papers were included in this research. The number of annual publications has increased, as has the number of domains in which SNOMED is being used. Theoretical studies mainly concern comparison of SNOMED to other terminological systems and SNOMED as an illustration of a terminological systems' theory. Few studies are available on the usage of SNOMED in clinical practice, largely involving coding information and retrieval/aggregation based on SNOMED codes.
The clinical application of SNOMED is broadening beyond pathology. The majority of studies concern proving the value of SNOMED in theory. Fewer studies are available on the usage of SNOMED in clinical practice. Literature gives no indication of the use of SNOMED for direct care purposes such as decision support.
在40年的时间里，系统化医学命名法（SNOMED）已从一种特定于病理学的命名法（SNOP）发展成为一种基于逻辑的医疗保健术语。尽管它存在已久且不断演变，但SNOMED在临床实践中的使用程度以及取得了哪些益处仍不为人知。本文的目的是通过概述已发表的研究来对此进行调查，这些研究对SNOMED的某个版本进行了研究或应用。
本文通过在PubMed中进行Medline文献检索，分析科学出版物中所反映的SNOMED随时间的使用情况。检索范围包括1966年至2006年6月的论文。对于每篇选定的论文，对以下特征进行分类：版本、医学领域、编码时刻（在护理过程中或之后）、用途以及评估类型（例如，SNOMED是否有效，SNOMED是否有帮助）。
本研究纳入了250篇论文。年度出版物数量有所增加，SNOMED的使用领域数量也有所增加。理论研究主要涉及将SNOMED与其他术语系统进行比较以及将SNOMED作为术语系统理论的例证。关于SNOMED在临床实践中的使用的研究很少，主要涉及基于SNOMED代码的编码信息和检索/汇总。
SNOMED的临床应用正在从病理学领域扩展。大多数研究关注在理论上证明SNOMED的价值。关于SNOMED在临床实践中的使用的研究较少。文献中没有表明SNOMED用于诸如决策支持等直接护理目的。
