自杀是一个重要的公共卫生问题,也是全球主要的死亡原因之一。自杀行为,包括自杀企图(SA)和自杀意念(SI),是自杀死亡的主要危险因素。与患者先前和当前SA和SI相关的信息经常记录在电子健康记录(EHR)笔记中。准确检测这些文件可能有助于改善对患者自杀行为的监测和预测,并提醒医疗专业人员采取预防自杀的措施。在这项研究中,我们首先构建了自杀企图和意念事件(ScAN)数据集,这是公开可用的MIMIC III数据集的一个子集,涵盖了12k+ EHR笔记,其中包含19k+注释的SA和SI事件信息。注释还包含诸如自杀企图的方法等属性。我们还提供了一个强大的基线模型ScANER(自杀企图和意念事件检索器),一个多任务的基于Roberta的模型,检索模块从住院期间的EHR记录中提取所有相关的自杀行为证据,并预测模块识别患者住院期间得出的自杀行为类型(SA和SI)。ScANER识别自杀行为证据的宏观加权F1评分为0.83,患者住院期间SA和SI分类的宏观F1评分分别为0.78和0.60。ScAN和ScANER是公开的1。
Suicide is an important public health concern and one of the leading causes of death worldwide. Suicidal behaviors, including suicide attempts (SA) and suicide ideations (SI), are leading risk factors for death by suicide. Information related to patients’ previous and current SA and SI are frequently documented in the electronic health record (EHR) notes. Accurate detection of such documentation may help improve surveillance and predictions of patients’ suicidal behaviors and alert medical professionals for suicide prevention efforts. In this study, we first built Suicide Attempt and Ideation Events (ScAN) dataset, a subset of the publicly available MIMIC III dataset spanning over 12k+ EHR notes with 19k+ annotated SA and SI events information. The annotations also contain attributes such as method of suicide attempt. We also provide a strong baseline model ScANER (Suicide Attempt and Ideation Events Retreiver), a multi-task RoBERTa-based model with a retrieval module to extract all the relevant suicidal behavioral evidences from EHR notes of an hospital-stay and, and a prediction module to identify the type of suicidal behavior (SA and SI) concluded during the patient’s stay at the hospital. ScANER achieved a macro-weighted F1-score of 0.83 for identifying suicidal behavioral evidences and a macro F1-score of 0.78 and 0.60 for classification of SA and SI for the patient’s hospital-stay, respectively. ScAN and ScANER are publicly available1.
