| ChatEHR, is a system that enables the use of LLMs with the entire patient timeline spanning several years. ChatEHR enables automations - which are static combinations of prompts and data that perform a fixed task - and interactive use in the electronic health record (EHR) via a user interface (UI). The resulting ability to sift through patient medical records for diverse use-cases such as pre-visit chart review, screening for transfer eligibility, monitoring for surgical site infections, and chart abstraction, redefines LLM use as an institutional capability. This system, accessible after user-training, enables continuous monitoring and evaluation of LLM use. | 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: |

| {{ :chatehr.png?nolink& }} | - 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. |

| ArXiv submission: https://arxiv.org/abs/2602.00074 | This [[https://arxiv.org/abs/2602.00074 | 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 ... |
