Abstract

Named entity recognition is a foundational method in clinical natural language processing that transforms unstructured text into structured, analyzable data by identifying key medical concepts such as medications, diagnoses, procedures, and vital signs. This report explores the role of named entity recognition in enhancing anaesthesia informatics and postoperative outcome prediction, drawing on insights from the Anaesthesia CareNet study by Xu et al. The study implemented a multi-layered framework that applied entity recognition to perioperative clinical narratives, enabling the extraction of rich, context-sensitive variables that were previously inaccessible through structured data fields alone. By integrating these variables into predictive models, the system significantly improved forecasting of patient recovery trajectories. Tables and visualizations—including entity distribution summaries, precision-recall performance metrics, and inter-annotator agreement scores—demonstrate the reliability and interpretability of the approach. The report also outlines essential dataset characteristics for deploying named entity recognition in clinical contexts and highlights both the strengths and limitations of current methods. Looking ahead, the integration of advanced language models, contextual embeddings, and real-time analytics will be pivotal for improving accuracy and clinical utility. Named entity recognition stands as a critical tool for scaling precision medicine and operationalizing narrative health data in anaesthesia care and beyond.
