Hospitals rapidly adopt clinical AI documentation tools

US hospitals utilizing the Epic electronic records platform are rapidly adopting ambient AI documentation tools. A study in the American Journal of Managed Care found that 62.6% of Epic-using hospitals had implemented these tools by mid-2025. Physician use of voice-based documentation rose from 20% to 29% in less than a year. Major products driving this trend include DAX Copilot, Abridge, and ThinkAndor.

Adoption rates vary significantly by facility type and geography. Nonprofit hospitals showed a 70.2% adoption probability compared to 28.8% for for-profit facilities, with higher uptake in the South than in the Midwest. This uneven diffusion raises concerns regarding potential disparities for resource-constrained hospitals.

As these ambient AI scribes are currently classified as administrative tools rather than medical devices, they fall outside FDA oversight. This rapid deployment has outpaced the development of governance frameworks and accountability rules.

To manage these complex digital environments, healthcare enterprises are increasingly adopting a dual-system architecture. This strategy uses legacy Electronic Health Record (EHR) platforms, such as Epic or Oracle Cerner, as a ‘system of record’ for clinical truth and billing, while deploying engagement layers like Salesforce Health Cloud to handle patient communication and care coordination.
