On March 20, Nuance Communications (a health tech company now part of Microsoft) introduced Dragon Ambient eXperience (DAX) Express, a new AI-powered clinical documentation application.

Here are five key points:

  • The app uses conversational, ambient, and generative AI to generate clinical notes that clinicians can review and complete following each patient visit.
  • It is the first clinical documentation tool to use OpenAI’s newest large language model, GPT-4, in conjunction with conversational and ambient AI.
  • Its main goal is to decrease administrative load and free up professionals’ time to interact with patients.
  • Dax Express is HIPAA-compliant.
  • It will be offered to over 550,000 product subscribers later this year.

Two things come to mind:

1/ I said it before, I’ll say it again (and probably again in the future): This move further confirms Microsoft’s willingness to monetize its significant investment in OpenAI.

2/ It’s another interesting use of generative AI technology in the clinical field following the release of DocsGPT (a tool integrating a GPT model that streamlines administrative tasks, including drafting and faxing pre-authorisation and appeal letters to health insurers).
