这项研究提出了一种新的自动方法,用于绘制临床分类系统,如国际疾病分类 (ICD). 该方法有效地解决了语言变异和细分问题,提高了绘图准确性.
科学领域:
- 医疗信息学 医疗信息学
- 自然语言处理自然语言处理.
- 计算语言学 计算语言学
背景情况:
- 绘制临床分类系统的地图,例如国际疾病分类 (ICD),至关重要但具有挑战性.
- 手动绘图是劳动密集型的,并且不可扩展.
- 现有的自动化方法在临床条件下与语言变化和不同的细粒度作斗争.
研究的目的:
- 引入一种自动映射方法,将预训练的编码器和大型语言模型 (LLM) 结合起来.
- 解决临床分类映射中的语言变异和细粒度不匹配问题.
主要方法:
- 为ICD代码生成的等级增强 (HA) 和LLM生成 (LG) 描述.
- 使用提示框架 (PR) 与LLM推理进行细分处理.
- 在ICD版本之间进行了各章节的映射 (ICD-9-CMICD-10-CM,ICD-10-AMICD-11).
主要成果:
- 建议的方法在所有ICD对和章节中始终优于基线方法.
- 将HA描述与LLM生成的描述相结合,最高-1准确度平均提高了6.5%.
- 在一项试点研究中,HA+LG方法在挑战一对多映射方面被证明是有效的.
结论:
- 将预训练的编码器与LLM推理集成,为自动ICD映射提供了强大的和可扩展的解决方案.
- 这种混合方法提高了临床分类系统映射的准确性和效率.
