Introduction

The recent paper by Ursin et al. () brings up crucial issues about the ethics of healthcare AI and more specifically autonomous AI. These issues include the responsibilities and liabilities of disclosing information to patients. We appreciate the authors illustrating these issues with IDx-DR, which as the first autonomous AI approved by US Food and Drugs Administration (FDA), crystallized so many issues around “a computer making a medical decision,” as the authors carefully point out.

Ethics in Healthcare Ai

During the development, validation, and implementation of IDx-DR (Digital Diagnostics Inc), we started with an ethical framework built on the principles of non-maleficence, autonomy, and justice, which continue to be developed in various publications (). This framework made it possible to track metrics around safety, equity, efficiency, transparency, validability, and accountability, allowing AI to be done the right way. This has led to validation of this biomarker-based AI under FDA oversight, inclusion in standards of care. An important milestone was reimbursement at the $55 level by publicly funded insurance in the United States. This required an understanding of the value of “autonomous AI work” by all stakeholders, and has led to rapid and increasingly widespread implementation (). The ethical framework thus continues to serve all stakeholders well, as we continue to jointly develop considerations and requirements for healthcare AI.

In this context, it is interesting to contrast healthcare autonomous AI, to another type of digital technology, social media. Healthcare autonomous AI was grounded from the start in an ethical framework, and the technology stack was then built according to this framework. Social media, instead, started with the tech, and only now, almost two decades later, are we starting to grapple with its ethical consequences.

Clarifying Several Issues of Note

  • a. IDx-DR is a fully autonomous AI system. While the authors refer to IDx-DR as “AI-aided DR diagnosis,” it is in fact a fully autonomous AI system, as explained above. As a consequence, Digital Diagnostics assumes liability for the performance of the AI, as is now also required by the American Medical Association's AI Policy (). We remain convinced that clarifying this liability issue helps foster acceptance by physicians and other stakeholders.

  • b. AI bias. The authors rightfully bring up the problem of undesirable bias, including racial and ethnic bias. In Digital Diagnostics' ethical framework, including metrics for equity, we recognize that the bias problem applies to the entire AI lifecycle. This includes choice of disease and disease severity to be diagnosed, AI algorithm design, including the use of priors such as biomarkers, instead of prior-less blank slate black box algorithms, the distribution of the training sets, rigorous validation for improved outcome metrics including equity, and the choice of where it is implemented after regulatory approval (, ). As illustrated in these studies, IDx-DR is a biomarker based AI system, and explicitly not a black box system, avoiding the latter's' many risks, including catastrophic failure and risk of bias ().

  • c. Patient informed consent. The authors are correct that informed consent of patients, notifying them that an AI will be used, should be considered. For IDx-DR, both operators of the AI system, as well as the physicians ordering it, are trained in how to discuss the use of IDx-DR with patients. In fact, Digital Diagnostics has developed an AI facts label as part of the diagnostic output, so as to maximize transparency about which AI algorithms are used, their accuracy, and the relevant scientific evidence of their use and benefit.

  • d. CE Certification. Finally, IDx-DR was for autonomous use in the European Economic Area per its CE Certificate () and complies with GDPR Article 22.
