UKHSA’s Innovative Use of AI in Public Health

The UK Health Security Agency showcases innovative AI applications in public health, including improving patient experience analysis, detecting food-borne illness outbreaks, and ensuring consistency in health guidance. These projects highlight AI’s potential in enhancing public health measures while maintaining a focus on human expertise and validation.

The UK Health Security Agency (UKHSA) is pioneering the use of artificial intelligence (AI) to tackle public health challenges, showcasing innovative projects aimed at enhancing health security. Here are three notable applications utilizing cutting-edge AI technology to improve and safeguard public health.

Firstly, the agency is leveraging AI to better understand patient experiences, which is essential for enhancing healthcare services. Traditionally a labor-intensive task, analyzing qualitative survey data is now expedited through Large Language Models (LLMs). In a recent analysis of the Positive Voices 2022 survey regarding HIV, the AI system efficiently highlighted core themes from over 1,600 responses about the concept of U=U (Undetectable = Untransmissible). While still undergoing human validation, this technology illustrates the transformative potential of AI in qualitative public health research.

In another project, UKHSA employs AI to identify food-borne illness outbreaks. With millions affected each year, traditional surveillance often misses many cases. By analyzing thousands of online reviews with various LLMs, the team searches for terms associated with gastrointestinal symptoms, like diarrhea and vomiting, as well as specific food types. Although similar studies exist, UKHSA’s comprehensive approach, focused on diverse language patterns, offers deeper insights into outbreaks. Addressing challenges related to data access and quality will be crucial before this method can be widely adopted.

The focus also extends to making public health guidance more consistent through AI technology. During health emergencies, clear guidance becomes paramount for both the public and professionals. UKHSA is currently testing an AI-powered tool using secure LLMs to automatically detect conflicts within guidance documents. Users can upload new guidance pieces, and the system flags any inconsistencies against existing UKHSA recommendations, showing promising results with over 90% accuracy in retrieving relevant text.

Looking to the future, AI’s potential in public health applications continues to grow. Dr. Nick Watkins from UKHSA pointed out that these projects exemplify how AI, in conjunction with human expertise, can significantly enhance public health protection. The agency remains committed to balancing innovation with robust validation of AI outputs to uphold its high standards.

The UKHSA is at the forefront of integrating AI into public health, with projects focusing on understanding patient experiences, detecting food-borne illnesses, and ensuring consistent guidance. Each initiative embodies the transformative potential of AI while emphasizing the importance of human oversight and rigorous validation. As these technologies evolve, public health strategies will likely become more efficient and effective, promoting better health outcomes for all.
