The possibility of post-coordination of SNOMED CT concepts, especially by clinical users, is both an asset and a challenge for SNOMED CT implementation. To get insight in the applicability of post-coordination, we analyzed scenarios for user-directed coordination that are described in the documentation of SNOMED CT. The analyses were based on experiences from previous and ongoing research and implementation work, including national mapping projects, and investigations on collection of data for multiple uses. These scenarios show various usability and representation problems: high number of relationships for refinement and qualification, improper options for refinement, incorrect formal definitions, and lack of support for applying editorial rules. Improved user-directed coordination in SNOMED CT in real practice requires advanced sanctioning, increased consistency of definitions of concepts in SNOMED CT, and real-time analysis of the post-coordinate expression.
SNOMED CT概念后协调的可能性，尤其是临床用户进行的后协调，对于SNOMED CT的实施而言既是一项资产，也是一项挑战。为了深入了解后协调的适用性，我们分析了SNOMED CT文档中描述的用户导向协调场景。这些分析基于以往和正在进行的研究及实施工作的经验，包括国家映射项目以及对多用途数据收集的调查。这些场景显示出各种可用性和表示问题：用于细化和限定的关系数量众多、细化选项不当、形式定义不正确以及缺乏对应用编辑规则的支持。在实际应用中改进SNOMED CT中的用户导向协调需要先进的审批、提高SNOMED CT中概念定义的一致性以及对后协调表达式进行实时分析。
