LLM's in Healthcare AI: does the evidence match the hype?



Exec Summary


There is a growing body of evidence that suggests that large language models (LLMs) can be effective in a variety of healthcare applications. For example, studies have shown that LLMs can be used to:


  • Extract insights from clinical text analysis: LLMs have been shown to be able to extract insights from unstructured clinical texts, such as electronic health records, discharge summaries, and clinical notes, with high accuracy. This can help clinicians identify trends and patterns, make more informed decisions, and improve patient care.

  • Answer patient queries: LLMs have been shown to be able to answer patient questions about their health, medications, and treatments with high accuracy. This can help patients get the information they need quickly and easily, and it can also free up clinicians' time so they can focus on more complex tasks.

  • Provide clinical decision support: LLMs have been shown to be able to provide clinical decision support to clinicians by helping them make more informed decisions about patient care. For example, LLMs can be used to identify potential drug interactions, suggest treatment options, and predict patient outcomes.

  • Accelerate medical research: LLMs have been shown to be able to analyze large datasets of medical research literature to identify new insights and trends. This can help accelerate the pace of medical discovery and lead to new and better treatments for patients.

However, it is important to note that LLMs are still a relatively new technology, and more research is needed to fully validate their effectiveness in healthcare settings. Additionally, it is important to use LLMs responsibly and to be aware of their potential limitations.


For example, LLMs can be biased, and they can sometimes generate inaccurate or misleading information. Therefore, it is important to carefully review the output of LLMs and to consult with human experts before making any decisions based on their output.

LLMs are still a relatively new technology, but they have the potential to revolutionize healthcare. By automating tasks, improving diagnosis and treatment, and supporting research, LLMs can help to make healthcare more efficient, effective, and accessible.


Here are some specific examples of how LLMs are being used in healthcare:


  • InteliHealth: InteliHealth is a US-based company that uses LLMs to create personalized health plans. Patients can use the InteliHealth website to answer questions about their health and lifestyle. The LLM will then generate a personalised plan that includes recommendations for diet, exercise, and medication.

  • Google Health: Google Health is a personal health record (PHR) that uses LLMs to help patients manage their health. Patients can use Google Health to track their medical history, medications, and symptoms. The LLM can then generate reports and insights that can help patients to better understand their health.

  • Viz.ai: Viz.ai is a company that uses LLMs to develop software that can help doctors to diagnose strokes and other brain injuries more quickly and accurately. Viz.ai's software uses LLMs to analyse medical images, such as CT scans and MRI scans, and to identify potential abnormalities.

  • GNS Healthcare: GNS Healthcare is a company that uses LLMs to develop software that can help clinicians to make better treatment decisions. GNS Healthcare's software uses LLMs to analyse patient data, such as medical records, laboratory results, and imaging data, to identify the best course of treatment for each individual patient.

  • Health Catalyst: Health Catalyst offers a variety of LLM-powered solutions for healthcare organizations. For example, Health Catalyst's LLM-powered platform can be used to identify patients who are at high risk for certain conditions, such as heart disease and diabetes. This information can then be used to develop targeted prevention and intervention programs

These are just a few examples of how LLMs are being used in healthcare. As LLMs continue to develop, we can expect to see even more innovative and effective applications of this technology in the years to come.

Final Thoughts


Large language models (LLMs) are a subset of deep learning. Deep learning is a type of machine learning that uses artificial neural networks to learn from data.


Neural networks are inspired by the structure and function of the human brain, and they are made up of layers of interconnected nodes.


Each node performs a simple mathematical operation, and the nodes are connected in such a way that the output of one node becomes the input to the next node.


LLMs are a type of deep learning model that is specifically designed to learn and process language. LLMs are trained on massive datasets of text and code, and they learn to identify patterns and relationships in language.


This allows LLMs to perform a variety of tasks, such as generating text, translating languages, and answering questions in a comprehensive and informative way.


Some of the most popular LLMs include GPT-3, LaMDA, and PaLM. These models have been shown to be capable of performing a wide range of tasks, including:


  • Generating text that is indistinguishable from human-written text

  • Translating languages with high accuracy

  • Answering questions in a comprehensive and informative way, even when they are open ended, challenging, or strange

  • Writing different kinds of creative text formats of text content, like poems, code, scripts, musical pieces, email, letters, etc.

LLMs are still under development, but they have the potential to revolutionise the way we interact with computers and the world around us.
