Little information exists concerning SNOMED CT (systematized nomenclature of medicine-clinical terms) users. This report describes current impressions and preferences of direct SNOMED CT users regarding coverage, quality, and concept details, and the change request mechanism.
A 43-question anonymous survey distributed electronically to relevant online communities.
Data on user demographic characteristics, modes and purposes of use, means and frequencies of access, satisfaction with SNOMED CT content coverage and quality and with the change request mechanism were recorded.
The survey was conducted in January 2010 and elicited 215 responses. Details regarding users' profiles, modes of use and access were reported elsewhere. The coverage of SNOMED CT was perceived to be at least 85% complete by 42% of responders, and 60% were at least satisfied with its quality. Various deficiencies were encountered at least 'somewhat often' by 28-61% of responders. Incorrect data were more bothersome than missing data. Users indicated that significant resources should be allocated to more consistent and complete conceptual representations and to further enhance content coverage. Enhanced synonym coverage and the introduction of textual definitions were important to users (54% and 63%, respectively).
A survey format with limited control over recruitment and selection bias. Lack of information regarding the SNOMED CT version used by responders.
Despite overall satisfaction, direct users indicated a strong desire to improve consistency, quality, and completeness of conceptual representations and concept details, as well as a continued desire to expand coverage. The survey provides much needed data for informed decisions regarding the use and development goals of SNOMED CT. Focused periodical surveys are warranted.
有关 SNOMED CT（医学术语系统命名法）用户的信息很少。本报告描述了直接 SNOMED CT 用户对覆盖范围、质量和概念细节以及变更请求机制的当前印象和偏好。
通过电子邮件向相关在线社区分发了一份 43 个问题的匿名调查。
记录了用户人口统计学特征、使用模式和目的、访问方式和频率、对 SNOMED CT 内容覆盖范围和质量以及变更请求机制的满意度的数据。
该调查于 2010 年 1 月进行，共收到 215 份回复。用户个人资料、使用模式和访问方式的详细信息已在其他地方报告。42%的受访者认为 SNOMED CT 的覆盖范围至少达到 85%，60%的受访者对其质量至少感到满意。28-61%的受访者至少遇到过一些不足之处。错误的数据比缺失的数据更令人烦恼。用户表示，应该投入大量资源来提高概念表示和进一步增强内容覆盖范围的一致性和完整性。增强同义词覆盖范围和引入文本定义对用户很重要（分别为 54%和 63%）。
调查格式对招募和选择偏差的控制有限。缺乏关于回复者使用的 SNOMED CT 版本的信息。
尽管总体满意度很高，但直接用户表示强烈希望提高概念表示和概念细节的一致性、质量和完整性，并继续希望扩大覆盖范围。该调查为有关 SNOMED CT 的使用和开发目标的决策提供了急需的数据。有必要进行定期调查。
