Clear and efficient patient communication is vital to effective care delivery, yet traditional patient portal messaging often results in inefficiencies, delays, and frustration. This session delves into a transformative use case of large language models (LLMs) to revolutionize patient-provider interactions. Discover how LLMs empower patients to draft precise, comprehensive messages that minimize delays and improve care outcomes. Using innovative lightbox visualization technology, presenters will illustrate the practical application of LLMs, share real-world experiences in implementation, and discuss strategies for building trust in AI through effective piloting and stakeholder engagement.
