      10 Use-Cases of Natural Language Processing (NLP) in Healthcare

      Jun 30, 2023

      4 minute read

      In recent years, advancements in technology have transformed industries, including healthcare. One such breakthrough is Natural Language Processing (NLP).

      A branch of artificial intelligence, NLP focuses on the interaction between computers and human language.

      By understanding and interpreting human language, it enables healthcare organizations to unlock valuable insights from vast amounts of unstructured data.

      In this blog post, we’ll explore the use-cases of NLP in healthcare and how it is transforming the industry.

      The 101 of Natural Language Processing (NLP)

      Natural Language Processing involves the ability of computers to understand, interpret, and respond to human language in a meaningful way. It encompasses several techniques such as:

      • Text Analysis
      • Sentiment Analysis
      • Speech Recognition
      • Machine Translation

      NLP algorithms are trained on large datasets, allowing them to learn patterns and extract valuable information from unstructured text.

      NLP Market Analysis & Recent Developments

      The NLP market in healthcare has experienced significant growth in recent years. For instance, the global NLP in healthcare and life sciences market was valued at USD 1.88 billion in 2021 and is expected to grow in value to $8.18 billion by 2030[i].


      The increasing adoption of electronic health records (EHRs), advancements in machine learning algorithms, and the need for efficient data analysis are some of the factors driving this growth.

      How Does NLP Work in Healthcare?

      NLP leverages machine learning algorithms and linguistic rules to analyze and understand human language.

      It can process vast amounts of unstructured data, such as clinical notes, research papers, social media posts, and patient feedback, and transform it into structured, actionable insight.

      NLP algorithms can extract key information, identify patterns, classify data, and generate summaries, enabling healthcare professionals to make informed decisions.

      Empowering Healthcare Professionals: 10 Ways NLP is Enhancing Patient Care

      From unraveling complex medical records to extracting vital insights from unstructured data, here are 10 use-cases of NLP that are transforming the healthcare industry:

      1. Enhancing Clinical Documentation: NLP can automatically extract relevant information from clinical notes and transcribe it into structured formats, improving accuracy and efficiency in documentation.

      2. Facilitating Clinical Trial Matching: NLP algorithms can analyze patient data and match them with relevant clinical trials, enhancing patient recruitment and participation in research studies.

      3. Supporting Clinical Decision Support (CDS): NLP-powered CDS systems can analyze patient data, medical literature, and guidelines to provide real-time recommendations to healthcare professionals, improving diagnosis and treatment planning.

      4. Improving Patient Health Awareness: NLP can analyze patient-generated data, such as online health forums and social media posts, to gain insights into patient experiences, sentiments, and preferences, enabling personalized care.

      5. Enhancing Care Quality: NLP can analyze structured and unstructured data to identify quality issues, such as medication errors or adverse events, enabling proactive intervention and improving patient safety.

      6. Identifying High-Risk Patients: NLP algorithms can analyze patient data, including clinical notes and diagnostic reports, to identify patients at risk of developing certain conditions, facilitating early intervention and preventive measures.

      7. Enhancing Patient Experience: NLP-powered chatbots and virtual assistants can understand and respond to patient queries and provide personalized healthcare information, improving patient satisfaction and engagement.

      8. Facilitating Medical Billing, and Coding: NLP can automate the coding process by analyzing clinical documentation, reducing errors, and improving billing accuracy and efficiency.

      9. Conducting Predictive Analytics: NLP algorithms can analyze historical patient data and identify patterns to predict disease progression, readmissions, and treatment outcomes, enabling proactive care and resource allocation.

      10. Data Mining Research: NLP techniques can analyze large volumes of research articles, clinical trials, and medical literature to extract relevant information, accelerating medical research and knowledge discovery.

      How Healthcare Organizations Can Leverage NLP

      Healthcare organizations can leverage NLP in several ways:

      • Invest in NLP-enabled EHR Systems: Integrating NLP capabilities with electronic health record (EHR) systems can streamline data entry, improve documentation accuracy, and enhance the efficiency of data retrieval and analysis.
      • Implement NLP-powered Clinical Decision Support Systems (CDSS): CDSSs that utilize NLP algorithms can provide real-time recommendations and evidence-based insight to healthcare professionals, aiding in diagnosis, treatment planning, and medication management.
      • Deploy NLP-based Chatbots and Virtual Assistants: Chatbots and virtual assistants equipped with NLP capabilities can handle patient queries, provide personalized health information, and assist in scheduling appointments, enhancing patient engagement and satisfaction.
      • Collaborate With NLP Technology Providers: Healthcare organizations can partner with NLP technology providers to access advanced NLP tools and expertise. Collaboration can involve developing customized NLP solutions tailored to specific organizational needs.
      • Leverage NLP for Research and Data Mining: NLP techniques can help researchers extract valuable insights from medical literature, research articles, and clinical data. This can accelerate the discovery of new treatments, identify trends, and support evidence-based decision-making.
      • Train and Educate Staff: Organizations can invest in training programs to educate healthcare professionals and staff about NLP and its applications in healthcare. This will help them effectively utilize NLP tools.

      The Future of Healthcare With NLP

      The adoption of NLP in healthcare is poised to grow rapidly as organizations recognize its potential to transform the industry. With the ability to analyze and interpret human language, NLP can unlock valuable insights from unstructured data sources, enabling personalized care, improved decision-making, and enhanced patient outcomes.

      As NLP technology continues to evolve, it holds the promise of revolutionizing healthcare delivery, research, and patient engagement. Healthcare organizations that embrace NLP and leverage its capabilities will stay at the forefront of innovation, driving improvements in care quality, efficiency, and patient satisfaction.

      The Bottom Line

      Natural Language Processing (NLP) is a powerful tool with numerous applications in healthcare. From enhancing clinical documentation to facilitating medical billing, NLP can streamline processes, improve patient care, and enable data-driven decision-making. By harnessing the potential of NLP, healthcare organizations can usher in a new era of efficient, personalized, and patient-centric healthcare.
