前瞻性临床行动,即决定患者下一步会发生什么的随访、医嘱、转诊和指示,目前以碎片化的形式标注在各种不兼容的语料库中:每个语料库仅记录一个文本片段和一个粗略类别。我们引入了临床意图提取(CIE)任务,即将这些行动恢复为完整的结构化记录,并提出了临床意图表示(CIR),该表示将每个行动分解为其动词、类型、编码目标、时间和条件,并增加了先前数据集未共同表示的两个轴:请求意图,即行动背后的权威(提议、计划、医嘱或选项,与HL7 FHIR对齐),以及模态,即临床强度的七级量表。将五个异构语料库(CLIP、MedDec、ap_parsing、PaniniQA、SIMORD)重新表示为CIR,得到CIRCA:涵盖两种笔记分布的10,011个统一意图,并包含人工验证的子集、源到CIR的交叉映射,以及确定性的FHIR R4映射器。CIRCA通过三模型共识构建,自动接受高一致性意图,并将其余意图交由人工审查;经审计的一致性层级与人工决策的匹配率为88.4%。对五个现有模型进行无任务特定训练的基准测试,揭示了CIRCA所针对的差距:给定片段,它们能很好地标注类型(85%至91%),但四个封闭字段全部正确的概率仅为18%至35%。所有工件均已发布,其中MIMIC衍生的层以独立标注的形式共享,需通过PhysioNet凭证访问。

英文摘要

Prospective clinical actions, the follow-ups, orders, referrals, and instructions that deter-mine what happens to a patient next, are annotated today in thin fragments across incom-patible corpora: each records a text span and one coarse category. We introduce Clinical Intent Extraction (CIE), the task of recovering these actions as complete structured rec-ords, and the Clinical Intent Representation (CIR), which decomposes each action into its verb, type, coded target, timing, and condition, and adds two axes prior datasets do not jointly represent: request-intent, the authority behind the action (proposal, plan, order, or option, aligned to HL7 FHIR), and modality, a seven-valued scale of clinical strength. Re-expressing five heterogeneous corpora (CLIP, MedDec, ap_parsing, PaniniQA, SIMORD) in the CIR yields CIRCA: 10,011 harmonized intents spanning two note distributions, with a human-validated subset, source-to-CIR crosswalks, and a deterministic FHIR R4 mapper. CIRCA is built by three-model consensus that auto-accepts high-agreement in-tents and routes the rest to human review; the audited agreement stratum matches human decisions 88.4% of the time. Benchmarking five existing models without task-specific training exposes the gap CIRCA targets: given the span, they label type well (85 to 91%) but get all four closed fields right only 18 to 35% of the time. All artifacts are released, with MIMIC-derived layers shared as stand-off annotations under PhysioNet credentialed access.
