AI Summary

Regulatory data on AI-enabled medical devices (AIMDs) in China are fragmented and inefficiently analyzed, impeding evidence-based oversight. Method: Leveraging over 4 million NMPA registration records, we developed the first reproducible, dynamically updatable, data-driven analytical framework for AIMDs. It integrates natural language processing with rule-enhanced information extraction to construct a structured regulatory text model and a multi-level classification taxonomy, enabling automated identification and categorization of AIMDs. Contribution/Results: The study provides the first systematic characterization of approved AIMDs in China: 43 distinct products comprising 531 standalone software instances and 1,643 embedded modules. Clinical applications are concentrated in respiratory medicine (20.5%) and ophthalmology/endocrinology (12.8%). This framework significantly improves analytical efficiency and cross-temporal comparability of regulatory data, offering both methodological rigor and empirical grounding for AI-in-healthcare regulatory science.

Abstract

Artificial intelligence (AI) in medical device software (MDSW) represents a transformative clinical technology, attracting increasing attention within both the medical community and the regulators. In this study, we leverage a data-driven approach to automatically extract and analyze AI-enabled medical devices (AIMD) from the National Medical Products Administration (NMPA) regulatory database. The continued increase in publicly available regulatory data requires scalable methods for analysis. Automation of regulatory information screening is essential to create reproducible insights that can be quickly updated in an ever changing medical device landscape. More than 4 million entries were assessed, identifying 2,174 MDSW registrations, including 531 standalone applications and 1,643 integrated within medical devices, of which 43 were AI-enabled. It was shown that the leading medical specialties utilizing AIMD include respiratory (20.5%), ophthalmology/endocrinology (12.8%), and orthopedics (10.3%). This approach greatly improves the speed of data extracting providing a greater ability to compare and contrast. This study provides the first extensive, data-driven exploration of AIMD in China, showcasing the potential of automated regulatory data analysis in understanding and advancing the landscape of AI in medical technology.
