Regard extends its diagnosis suggestion tool from hospital medicine into cardiology and surgery

Regard's software reads the whole chart and suggests a diagnosis before the doctor walks into the room. Until now it mostly covered hospital medicine, about half of admitted patients. The company says cardiology and surgery are next, and one health system is testing it.

What Regard Announced About Its Cardiology and Surgical Expansion

Regard said on 24 March 2026 that it expanded its platform into cardiology and surgical service lines, having previously focused on hospital medicine, which it says covers roughly 50 to 55 percent of patients admitted to hospitals. The company describes the platform as reviewing all the data in the electronic health record to recommend a diagnosis and generate draft documentation in the physician's workflow at the point of care, with evidence attached, before the physician enters the patient's room. It names The Guthrie Clinic as piloting the expanded platform across additional service lines, and says its technology is used by thousands of clinicians across more than 150 hospitals and has recommended millions of diagnoses that would otherwise have been missed.

Why the Regard Specialty Expansion Matters to Hospital Medicine Leaders

Moving from hospital medicine into cardiology and surgery roughly doubles the patients a tool like this touches, and that changes the review burden rather than just the licence count, because a surgical chart raises different questions than a general medical one. The claim that millions of diagnoses would otherwise have been missed is the company's own and is not independently verified; a suggested diagnosis is a prompt for a physician, not a finding, and that distinction is the whole safety argument for this category. The Guthrie Clinic is described as piloting, so treat the expansion as in testing rather than proven in the new specialties.

How We Would Research the Regard Specialty Expansion

The source gives us the starting point. This is how we would build the next layer of research around it.

We would ask Regard how the missed diagnosis count is calculated and who adjudicated that each one was genuinely missed.
Then we would ask The Guthrie Clinic what the acceptance rate of suggestions is in cardiology compared with hospital medicine.
We would ask which population the cardiology and surgical models were validated on, since a model tuned on general medical admissions may behave differently on a surgical ward.
