Natural Language Processing (NLP) is revolutionizing the utilization of Electronic Health Records (EHR) by automating clinical summarization and patient risk stratification, thereby enhancing healthcare delivery. This chapter explores the integration of NLP technologies into EHR systems, highlighting their capacity to transform vast amounts of unstructured clinical data into actionable insights. Clinical summarization, a critical application of NLP, improves communication among healthcare providers and ensures continuity of care by generating concise, relevant summaries from comprehensive patient records. Through both extractive and abstractive summarization techniques, NLP facilitates efficient information retrieval, allowing clinicians to focus on key patient data.
