The primary goal of this project is to create a framework to extract Real-World Evidence to support Health Technology Assessment, Health Technology Management, Evidence-Based Maintenance, and Post Market Surveillance (as outlined in the EU Medical Device Regulation 2017/745) of medical devices using Natural Language Processing (NLP) and Artificial Intelligence. An initial literature review on Spontaneous Reporting System databases, Health Information Technologies (HIT) fault classification, and Natural Language Processing has been conducted, from which it clearly emerges that adverse events related to HIT are increasing over time. The proposed framework uses NLP techniques and Explainable Artificial Intelligence models to automatically identify HIT-related adverse event reports. The designed model employs a pre-trained version of ClinicalBERT that has been fine-tuned and tested on 3,075 adverse event reports extracted from the FDA MAUDE database and manually labelled by experts.
该项目的主要目标是创建一个框架,利用自然语言处理(NLP)和人工智能来提取真实世界证据,以支持医疗设备的卫生技术评估、卫生技术管理、循证维护和上市后监测(如欧盟2017/745号医疗器械法规所述)。已对自发报告系统数据库、健康信息技术(HIT)故障分类和自然语言处理进行了初步文献综述,从中可以清楚地看出,与HIT相关的不良事件随着时间的推移而增加。所提出的框架使用NLP技术和可解释人工智能模型来自动识别与HIT相关的不良事件报告。所设计的模型采用了ClinicalBERT的预训练版本,该版本已在从FDA MAUDE数据库中提取并由专家手动标注的3075份不良事件报告上进行了微调与测试。
