Mayo Clinic is expanding its use of artificial intelligence (AI) to help doctors spend less time reviewing medical records and more time caring for patients, according to a report by CNN.

One of the hospital’s newest AI tools, called Record Time, summarizes patient records, organizes medical documents chronologically, and makes them easier to search. The system is designed to help physicians quickly review years of medical history, particularly for patients seeking second or third opinions.

Dr. Alexander Ryu, an internal medicine physician at Mayo Clinic, told CNN the tool can save doctors between five and 30 minutes of preparation per patient, depending on the complexity of the case.

The hospital has deployed around 150 AI models across different clinical areas, according to Dr. Matthew Callstrom, medical director of Mayo Clinic’s generative AI program.

Beyond reducing administrative work, Mayo Clinic is also testing AI for early disease detection. One ongoing clinical trial is evaluating whether AI can identify pancreatic cancer years before it is typically diagnosed. The hospital has also used AI to analyze heart rhythms to help detect atrial fibrillation, a condition linked to strokes.

Mayo Clinic said all AI tools undergo rigorous testing similar to clinical trials before being introduced into patient care, with continued monitoring after deployment.

The expanded use of AI comes as healthcare providers increasingly explore how the technology can improve diagnosis, streamline documentation, and enhance patient outcomes.

However, the report noted that AI adoption in healthcare continues to raise questions about patient privacy and accuracy. Earlier this month, a former Mayo Clinic executive sued the hospital, alleging retaliation after raising concerns about oversight of certain AI systems. Mayo Clinic said it remains committed to the responsible development of AI and protecting patient privacy.

Experts interviewed by CNN said AI is unlikely to replace healthcare professionals but can reduce repetitive administrative work, allowing doctors and nurses to spend more time with patients.
