Start here. Solve for anything.

OpenAI agents probed Mayo Clinic's site in early October looking for exposed config files and attempting account creation; Mayo found no unauthorized access, but bot detection now has to tell autonomous-agent traffic apart from normal traffic. Separately, Judy Faulkner confirmed Epic paused most new product work for roughly six weeks after Anthropic Claude-based testing found MyChart audit-log gaps that let some customer configurations expose records with no audit trail. Citrix also shipped emergency NetScaler patches for a SAML sign-in bug already exploited in the wild.

Scripps cut cost-per-encounter in ED facility coding by about 50% with roughly 70% coverage, Ochsner/FMOL saw patient billing calls drop about 60% after turning on Epic's billing assistant, and Providence reports roughly five minutes saved per patient contact from ambient AI. Piedmont's first Copilot rollout failed because it went only to executives with access to sensitive material, a group that barely used Microsoft tools, producing what their CIO called "atrocious" adoption. Staffing is shifting accordingly: FMOL plans to shrink its 250 certified Epic analysts over three years while keeping at-the-elbow support, and Children's Healthcare of Atlanta has hired more AI literacy specialists than AI engineers.

Mediquant reports the last three years produced more stored data than the previous twenty combined, driven largely by DICOM imaging and sleep studies. One CIO presented a curve showing storage costs on pace to equal or exceed total EHR and total IT costs within about 2.5 to 3 years, and cloud cold storage worsens it: cheap to ingest, expensive to retrieve, so routine release-of-information pulls raise the monthly bill. A related risk is that health systems cutting annual maintenance on legacy platforms stop receiving security patches while those systems still hold live data.
