Interventions

  • GenAI Chart Summarization — OTHER
    Epic's generative AI chart summarization tool summarizes a subset of a patient's notes. Use of the tool is optional and intended solely to provide a summary for providers and does not provide clinical decision support. The system automatically selects recent notes or a provider can manually select specific notes of interest. The number of notes summarized is limited by the character constraints of the EHR, 24,000 English characters or 30 notes. The system uses AI to generate a short summary of relevant information. The summaries are meant to be used as a tool to aid providers and are not intended to be placed in clinical notes. The summaries created are currently not stored in the patient's chart.

Study Details

This is a RCT of 284 outpatient physicians at a large academic health system, randomized 1:1 to an electronic health record (EHR) produced generative AI outpatient chart summarization tool or a usual-care control group. The 90 day study will observe the effects of the tool prior to system-wide roll out of the tool.
