Nuance Communications, a speech recognition company owned by Microsoft, recently launched Dragon Ambient eXperience (DAX) Express. This clinical notes application leverages the power of artificial intelligence to generate a draft of clinical notes in mere seconds after a patient visit. The goal of DAX Express is to alleviate the administrative burden faced by health-care workers. The technology is powered by a combination of ambient AI that analyzes unstructured data, such as conversations, and OpenAI's latest model, GPT-4.

According to Diana Nole, the executive VP of Nuance’s healthcare division, the newly announced Dragon Ambient eXperience (DAX) Express aims to ease the administrative burden on healthcare workers and allow them to spend more time caring for patients. The clinical notes application, powered by a combination of ambient AI and OpenAI’s GPT-4 model, generates a draft of a clinical note within seconds of a patient visit. Microsoft acquired Nuance for approximately $16 billion in 2021, a company that earns revenue by selling speech recognition and transcription tools for use during medical office visits, customer-service calls, and voicemails.

DAX Express is designed to integrate with Nuance's Dragon Medical One speech recognition application, which is utilized by over 550,000 physicians. Dragon Medical One is a cloud-based platform that enables doctors to operate clinical systems and quickly access patient data using their voices. The clinical notes generated by DAX Express will be accessible on the Dragon Medical One desktop. Furthermore, DAX Express is an extension of Nuance's original DAX application, launched in 2020, which translates spoken patient visits into clinical notes that are then reviewed by humans to ensure accuracy and quality. These notes are typically incorporated into the patient's medical record within four hours of the appointment.

Nole explained that Nuance believes that a combination of all the available tools would be essential as every medical specialty and patient encounter has distinct requirements. Therefore, DAX Express, which generates clinical notes within seconds, would work in conjunction with other services offered by Nuance to provide efficient tools for all types of medical visits.

Nuance Communications has announced the launch of Dragon Ambient eXperience (DAX) Express, a new clinical notes application for health-care workers. Powered by artificial intelligence (AI) and the latest model from OpenAI, GPT-4, the tool is designed to reduce clinicians' administrative burdens by automatically generating a draft of clinical notes within seconds after a patient visit. The technology is expected to be enabled through Nuance's Dragon Medical One speech recognition application, which is currently used by over 550,000 physicians. The company did not disclose the cost of the new application, but said the price varies based on the number of users and the size of a particular health system.

Nole emphasized that while AI will assist physicians and clinicians in performing administrative tasks, healthcare professionals are still involved in the entire process. DAX Express allows physicians to make necessary modifications to the generated notes, and they are responsible for reviewing and approving the final notes before they are added to a patient’s electronic health record.

The ultimate goal of using DAX Express is to improve both the patient and physician experience, according to Nole. With the technology handling administrative tasks, physicians can focus on providing better care for their patients and have more time to do so. The result is a more efficient healthcare system with better patient outcomes.

According to Nole, the use of DAX Express will result in improved patient and physician experiences, as it will enable face-to-face communication between the two parties, allowing patients to feel listened to and have a trusted experience.
