Good morning health tech readers!

Today, a close look at how a health system tested a sepsis algorithm. Plus a slew of updates from notable companies.

Artificial intelligence

Inside a sepsis algorithm test

In 2021, Ohio-based Summa Health had a problem. A technology tool alerted clinicians that patients were likely to develop sepsis, but the system produced as many as 80,000 flags a month.

Clinicians couldn't figure out which alerts to respond to, so they were often ignored. In a new story, Katie Palmer explores how Summa tested a new algorithm developed at Duke, called Sepsis Watch that would flag people at risk for Sepsis who needed help, without overwhelming clinicians. The case study is emblematic of the challenge of launching clinical decision support technology in hospitals, especially at community health systems.

Microsoft "superintelligence" hype misses the mark

At the end of June, Microsoft's AI team released a study on a new way to structure AI agents for diagnosing disease — one that was able to diagnose difficult cases at a rate four times higher than clinicians could. Those results led the company to claim it is on the path to "medical superintelligence."

The claims, and hyperbolic headlines that followed, have stirred controversy among physicians online. The "superintelligence" buzzword misses the mark, experts told STAT's Brittany Trang, and overlooks the actual innovations Microsoft made in the process.

To amend HIPAA or make something new?

Brittany Trang writes: At a Senate HELP committee hearing on health care cybersecurity yesterday, Sen. Bill Cassidy (R-La.) asked expert witnesses if anyone would object to medical information from wearables becoming covered under HIPAA, the federal law that protects health data privacy. The question follows health secretary Robert F. Kennedy Jr.'s suggestion that everyone in America ought to use a wearable to help manage their health.

One rural health system CIO said she had no objections. But René Quashie, vice president of digital health at the Consumer Technology Association, voiced opposition, saying that HIPAA wasn't the appropriate vehicle to safeguard wearables data.

"HIPAA is a health care law, for health care stakeholders," he said. The CTA instead supports the idea of a federal privacy law with "specific health provisions" that would cover the breadth of entities not currently covered by HIPAA for use cases beyond simply wearable data.

Congress has tried and failed to pass a comprehensive privacy bill multiple times. Whether it's easier to amend HIPAA to cover non-health care companies that handle medical data, or pass a new privacy law, is yet to be seen.

Updates from Samsung, Hims, Google, and more

  • Consumer technology giant Samsung yesterday announced a new Galaxy smartwatch with a bevy of new health and wellness features focused on sleep, stress, and more. An "Antioxidant Index," that hopes to guide people to a healthier lifestyle is honestly not something I thought I would see. 
  • Samsung also announced  it acquired Xealth, a Providence Health spinout that helps health systems manage many digital health products for patients through a single interface. Samsung said the acquisition will further the company's "push to unify fragmented health information." A major problem faced by consumer wearable companies with health care ambitions is efficiently getting data from users in front of clinicians who might be able to use it for care.
  • Hims and Hers Health announced it will in 2026 expand its weight loss program to Canada where it will offer a generic version of semaglutide which is losing its patent protection there.
  • Apple announced that chief operating officer Jeff Williams will retire and many of his responsibilities — including oversight of Apple Watch and the company's work in health — will be passed to Sabih Khan. Williams has long been the architect of Apple's health strategy and was the face of the effort until the company hired VP of health Sumbul Desai.
  • Fresh off its $70 million fundraise, AI-powered clinical documentation platform Nabla has a new arrangement so it works with Navina, an "AI-powered clinical intelligence platform for value-based care." Navina recently raised $55 million.
  • Hippocratic AI, a well-funded developer of AI agents for health care, is working with accounting and professional services firm KPMG. 
  • Google Research announced two new models in its MedGemma family of medical generative artificial intelligence models along with a heap of technical information.
