Problems and Analysis of Medical Terms Coding Using MedDRA Dictionary-based Medical TermsAutomatic Coding System
采用基于MedDRA词典的《医学术语自动编码系统》进行医学术语编码的问题和分析

摘要

目的 总结MedDRA编码的实践经验以提高药物临床试验数据编码的准确性。方法 通过回顾性分析20000个词汇的编码实践，以具体示例总结应用MedDRA在药物临床试验编码过程中遇到的各种情况及策略，包括词汇拆分、自动编码的审核和编码质疑。结果 自动编码系统的使用大大提高了编码的效率，同时也有一定的局限性。一词多义、多词一义、需要拆分和澄清的词汇都需要进行人工判断和编码，目前还不能由系统来替代。结论 当前，虽然自动编码系统的使用显著提高了工作效率，但是人工编码和医学审核的流程仍然是不可或缺的。

Abstract

Objective To summarize the practical experience of MedDRA coding to improve the accuracy of drug clinical trial data coding.
Methods Through a retrospective analysis of the coding practice of 20,000 words, various situations and strategies encountered during the coding of drug clinical trials using MedDRA were summarized with specific examples, including word splitting, automatic coding review and coding challenge.
Results The use of automatic coding system greatly improved the coding efficiency, but also had some limitations. Words with multiple meanings, multiple words with one meaning, and words that need to be split and clarified all require manual judgment and coding, and cannot be replaced by the system at present.
Conclusion   Currently, although the use of automatic coding systems has significantly improved work efficiency, the process of manual coding and medical review is still indispensable.
