LLM on FHIR in the Medical Sector

Large language models (LLMs) support clinicians with decision-making, documentation, and medical education. In addition to assisting healthcare providers, models like GPT have shown promise in improving patient understanding by answering health-related questions. 

Integrating these AI tools into mHealth solutions can make complex medical information more accessible, addressing challenges like language barriers and limited health literacy. Patients can benefit from more transparent, usable health data by adapting LLMs to work with FHIR within mobile apps. As healthcare organizations develop FHIR LLM apps, they set the stage for the next generation of digital health tools that make medical data accessible and understandable. 

Creating patient-facing LLM tools and evaluating their effectiveness through expert reviews is essential. These AI tools help present health records clearly and accurately, enabling patients to understand their health data better and empowering more informed decision-making.

SPsoft’s experience in implementing LLMs on FHIR has produced meaningful results:

Finding the Right Balance Between Art and Science

Modern RAG on FHIR and FHIR LLM applications demonstrate their versatility and efficiency in healthcare. They prove that quick, cost-effective methods like fine-tuning generic LLMs and using Prompt Engineering with tools such as OpenAI’s GPT-4 can effectively convert natural language into FHIR standards. 

However, because FHIR is such a broad standard, fine-tuning LLMs for every possible scenario would be time-consuming. Instead, developers can focus on refining models for specific use cases to achieve optimal results, emphasizing the need for precision in healthcare applications.

Conversational Queries vs. Structured Information Requests

While fine-tuning models through prompt engineering, SPsoft discovered that vague or imprecise prompts often led to incomplete responses. Thus, creating a user-friendly interface for non-technical users unfamiliar with FHIR standards is crucial. Crafting such a UI requires a deep understanding of prompt engineering techniques tailored to various scenarios.

Though this approach works well for general users, it raises the question of how results differ for advanced users like clinicians who understand the data structure. Advanced users can more effectively navigate the system, producing more precise outputs. Besides, character restrictions present a limitation, mainly for complex queries. Breaking down larger queries and intelligently merging responses provides a more complete answer.

Making Data More Accessible and Actionable

Extracting raw data from FHIR platforms is valuable, but often, the information could be more dense and more accessible to interpret. Health informatics has a growing opportunity to present data in more relevant and engaging formats. FHIR LLM applications now support various data presentation formats, including tables, graphs, and interactive charts, enabling users to visualize key insights more effectively. These visual formats improve data clarity and usability, helping medical professionals make data-driven decisions and understand vital takeaways.
