Understanding this regulatory environment is crucial for the successful development, deployment, and adoption of AI technologies in healthcare settings, as compliance failures can result in significant penalties, liability issues, and barriers to market access.

In the United States, the Food and Drug Administration (FDA) has emerged as the primary regulatory authority for healthcare AI systems, particularly those intended for diagnostic or therapeutic applications. The FDA has developed a risk-based framework for regulating AI/ML-based medical devices, categorizing them based on their intended use and potential risk to patients. This framework distinguishes between AI systems that are locked (static) and those that continuously learn and adapt, with different regulatory pathways for each category.

The FDA's Software as a Medical Device (SaMD) guidance provides a framework for classifying AI software based on the healthcare decision it informs and the healthcare situation or condition it addresses. This classification system helps determine the level of regulatory oversight required, ranging from Class I devices that require minimal oversight to Class III devices that require extensive clinical evidence and premarket approval.

The FDA has also introduced the concept of predetermined change control plans for AI systems that continuously learn and evolve, allowing developers to specify in advance the types of modifications their systems may make and the associated risk mitigation measures. This approach recognizes the unique characteristics of AI systems while maintaining appropriate safety oversight.

European regulation of healthcare AI is governed by the Medical Device Regulation (MDR) and the emerging AI Act, which together create a comprehensive framework for AI oversight in healthcare. The EU AI Act introduces a risk-based classification system for AI applications, with healthcare AI systems typically falling into high-risk categories that require conformity assessments, risk management systems, and ongoing monitoring.

The General Data Protection Regulation (GDPR) significantly impacts healthcare AI development and deployment in Europe by establishing strict requirements for personal data processing, including health data.
