The wide adoption of electronic health record systems in health care generates big real-world data that open new venues to conduct clinical research. As a large amount of valuable clinical information is locked in clinical narratives, natural language processing techniques as an artificial intelligence approach have been leveraged to extract information from clinical narratives in electronic health records. This capability of natural language processing potentially enables automated chart review for identifying patients with distinctive clinical characteristics in clinical care and reduces methodological heterogeneity in defining phenotype, obscuring biological heterogeneity in research concerning allergy, asthma, and immunology. This brief review discusses the current literature on the secondary use of electronic health record data for clinical research concerning allergy, asthma, and immunology and highlights the potential, challenges, and implications of natural language processing techniques.

人工智能方法使用自然语言处理来推进基于EHR的临床研究。

电子医疗记录系统在医疗保健中的广泛采用产生了大量的现实世界数据，这些数据为开展临床研究提供了新的场所。由于大量有价值的临床信息被锁定在临床叙事中，自然语言处理技术作为一种人工智能方法已被利用来从电子健康记录中的临床叙事中提取信息。这种自然语言处理能力可以自动进行图表审查，从而在临床护理中识别具有独特临床特征的患者，并减少定义表型的方法异质性，从而消除有关过敏，哮喘和免疫学研究的生物异质性。
