The Advanced Research Projects Agency for Health (ARPA-H), which operates under the U.S. Department of Health and Human Services, has recently initiated a program focused on enhancing the reliability and performance of medical devices that incorporate artificial intelligence (AI). This initiative arises from concerns that the effectiveness of AI-driven tools may deteriorate over time due to shifts in clinical practices, data collection methods, and patient demographics.
Despite the Food and Drug Administration (FDA) having approved approximately 950 medical devices that integrate AI and machine learning technologies, there are growing signs that the accuracy of these devices can diminish. The ARPA-H acknowledges that currently, these AI models are not subject to ongoing assessments during their clinical applications to guarantee consistent performance. Furthermore, there is no established protocol for updating AI systems that are not performing at their optimal capacity.
Traditionally, the detection of any decline in AI model performance has heavily relied on the clinical judgment of healthcare providers using the technology. However, the ARPA-H pointed out that this method is not only unreliable but also varies significantly, which can result in delayed recognition of AI failures, potentially leading to misdiagnoses.
To combat these issues, the ARPA-H has set up the Performance and Reliability Evaluation for Continuous Modifications and Usability of Artificial Intelligence (PRECISE-AI) program. This new initiative aims to develop tools that will actively monitor the performance of AI models in clinical settings, identify any degradation in performance, and implement corrections automatically without human intervention. This approach is intended to alleviate the burden currently placed on medical professionals and also aims to provide precise, actionable insights into the causes of performance deterioration.
PRECISE-AI is structured as a four-year program, with the first two years dedicated to the development and prototyping of new methodologies, followed by a two-year phase focused on testing these innovations in real-world clinical environments and preparing them for commercial distribution.
This program marks one of the first substantial efforts by the ARPA-H since its establishment by the Biden administration in 2022. The agency, inspired by the Defense Advanced Research Projects Agency model, is designed to propel forward medical and health advancements that are beyond the scope of conventional research and commercial ventures, emphasizing its commitment to tackling critical healthcare challenges through innovation in technology and AI.
