An Overview of Natural Language Processing in Analyzing Clinical Text Data for Patient Health Insights
Main Article Content
Abstract
Natural Language Processing (NLP) has emerged as a transformative technology in the healthcare industry, particularly in the analysis of clinical text data. Healthcare providers generate vast amounts of unstructured data in the form of clinical notes, electronic health records (EHRs), discharge summaries, and radiology reports. This unstructured data holds valuable insights into patient health, but it is often difficult to extract and interpret manually. NLP techniques, powered by machine learning and deep learning algorithms, enable the automated extraction, classification, and interpretation of clinical information. This paper provides an overview of how NLP is being utilized to analyze clinical text data, highlighting key applications such as disease prediction, risk stratification, clinical decision support, and patient outcome forecasting. Additionally, we discuss the challenges in applying NLP to healthcare data, including data privacy concerns, ambiguity in medical language, and the complexity of integrating clinical text data with structured health records. The paper concludes with a discussion on future trends and the potential for NLP to enhance personalized medicine, improve patient care, and streamline healthcare operations.
