Table of Contents
ChatEHR is a set of capabilities developed at Stanford Medicine, for using a set of Large Language Models (LLMs) with a single patient's longitudinal medical chart in context. There are two ways to use the ChatEHR capability:
- via a fixed prompt automation, which applies an existing set of criteria to a patient's record and returns a response based on that patient's record. Examples include decisions about transfer eligibility, referrals to certain services, and creating summaries of a hospital course of stay. About 60% of our usage is via automations.
- via a user interface, which is available as a tab inside of Epic Hyperspace to allow care providers (clinicians, nurses, pharmacists) to ask questions of a given patient's medical record. About 40% of usage is via the UI.
This ArXiv submission describes 7 automations and 1075 users have trained to become routine users of the UI, engaging in 23,000 sessions in the first 3 months of launch. Below is what users say …
