Amazon Web Services, Inc. (AWS) announced the release of its new service, AWS HealthScribe, at the AWS Summit New York on July 26, 2023. This latest service leverages speech recognition and generative AI to automatically create preliminary clinical documentation from patient-clinician interactions.

This move from AWS indicates an intensified competition with Microsoft’s Dragon Ambient eXperience (DAX) Express, which also uses AI to automate clinical note creation. As two of the largest tech companies globally, the parallel development of these healthcare AI solutions by AWS and Microsoft is expected to further disrupt the healthcare technology market.

AWS HealthScribe: An Overview

AWS HealthScribe enables healthcare software providers to build applications that convert patient-doctor conversations into structured clinical documentation. It extracts key details from these discussions, such as medical terms and medications, to create robust transcripts and summaries. This automated process not only saves time for clinicians but also enhances the efficiency of electronic health record (EHR) systems.

One of the standout features of AWS HealthScribe is its integration of Amazon Bedrock, which provides generative AI capabilities. This allows AWS HealthScribe to process and generate clinical notes for two medical specialties: general medicine and orthopedics.

AWS HealthScribe also adheres to strict privacy and security standards. It gives customers control over where their data is stored, encrypts data in transit and at rest, and does not use the data generated through the service to train its models.

AWS HealthScribe vs. Microsoft’s DAX Express

In March 2023, Microsoft’s Nuance announced the Dragon Ambient eXperience (DAX) Express, a solution that employs OpenAI‚Äôs GPT-4 to create clinical notes in seconds. Like AWS HealthScribe, DAX Express is designed to alleviate the administrative burden on healthcare professionals by automating the process of clinical documentation.

However, while both AWS HealthScribe and Microsoft’s DAX Express aim to streamline clinical documentation using AI, there are a few distinct differences:

  1. Model Training: While both solutions leverage advanced AI, AWS HealthScribe uses Amazon Bedrock for its generative AI capabilities, whereas DAX Express uses OpenAI’s GPT-4.
  2. Market Availability: AWS HealthScribe is immediately available to healthcare software providers, whereas DAX Express will only be available for private preview in the summer.
  3. Data Use: AWS explicitly states that it does not use the data generated through the service to train its models, whereas the data use policies for DAX Express have not been explicitly stated.

These two platforms reflect the growing trend of AI applications in healthcare, aiming to streamline processes, improve accuracy, and allow medical professionals more time for patient care. The competition between AWS HealthScribe and Microsoft’s DAX Express is set to push the boundaries of AI innovation in healthcare, ultimately leading to better patient outcomes.
