Bertalan Meskó, MD, PhD , Director of The Medical Futurist Institute in Hungary, emphasised the importance of technological equity, stating, "Health equity is not something that these digital health trends will be able to improve. Only governments can improve health equity by first improving technological equity". He further cautioned that even with the best digital health interventions, "if the target population, patients have no access to a smartphone, they cannot use our perfect solution".

Data privacy and security also represent a significant challenge. Generative AI relies on vast amounts of patient data, raising concerns about potential misuse or breaches. Dr. Mesko acknowledged this concern, stating, "We keep on asking whether we can retain or keep our privacy intact in the age of precision medicine, while, of course, we cannot because we cannot develop those AI algorithms without our precious data". He suggested reframing the question, asking instead, "How much of our privacy are we willing to give up in exchange for a chance for a long and healthier life?" as long as patients are the ones making the decisions about their data.

Farah Magrabi , Professor at Macquarie University, pointed out that clinicians are responsible for ensuring AI's safe and effective use. She emphasised the importance of clinicians understanding AI systems' limitations and verifying their outputs before making clinical decisions. She also stressed patient transparency, stating that clinicians "need to be transparent with patients that they are using these systems" and obtaining informed consent.

Regulatory frameworks need help keeping pace with the rapid advancements in generative AI. Existing medical device regulations may need to address the unique challenges posed by this technology adequately. Professor Magrabi noted that regulators are actively considering how best to regulate generative AI in healthcare, particularly given the dynamic nature of the models.

keren priyadarshini , General Manager, Healthtech: Data and AI, JAPAC at 微软 , discussed the potential of Azure Open AI services and highlighted the principles guiding Microsoft's AI development, including fairness, reliability, privacy and security, inclusiveness, transparency, and accountability. She also showcased examples of how generative AI can enhance patient experience, improve operational agility, and optimise commercial engagement and R&D in healthcare.

AI in Healthcare: Advancements and Concerns

The conference centres on AI's transformative role in healthcare, referencing Professor McRobbie's findings that current systems deliver only 60% of recommended care. Experts pointed out that while AI can enhance diagnostic accuracy and optimise resources, it is a complex solution and requires careful consideration of its complexities and potential pitfalls:

• The differences between traditional AI models and generative AI models in healthcare.
• Real-world applications of AI in improving diagnostic performance and proper resource allocation.

Addressing Bias in AI Systems

Experts discussed the potential for AI systems to inherit biases from their training data, which can lead to unfair treatment recommendations. A specific example was given about heart disease diagnosis, where a system trained primarily on male data could fail to recognise symptoms in women. Experts pointed out the necessity of diverse data to ensure accurate AI outcomes while they stressed the importance of involving various experts in the development process.

AI in Healthcare: Balancing Technology and Human Interaction

Experts raised concerns about the complexity of AI systems in healthcare, particularly the need for transparency to ensure doctors can trust AI recommendations. The conference also addressed the risk of de-skilling among healthcare professionals if they become overly reliant on AI, underscoring the necessity for ongoing training. Experts agreed that AI should be a supportive tool rather than a replacement for human expertise.

Key concerns surrounding AI in healthcare include bias, transparency, and the doctor-patient relationship.        

Data Privacy and Security in Healthcare AI

The Data Dilemma: Bias, Privacy, and Security

Professor Magrabi from Macquarie University highlighted the rapid advancements in generative AI, noting, "Tech giants are engaged in a race to build ever more powerful AI. We are seeing these developments literally every couple of months". This rapid evolution creates difficulties for regulators, as Professor Magrabi further explained, "The issue here is where the answer that it gives you each time is different. And so, how do you regulate something where you can't lock the model?".

One of the most significant concerns is the potential for bias in AI algorithms, which can lead to disparities in care. This bias can stem from the data used to train the algorithms, reflecting societal inequalities.?

Ensuring Accuracy, Reliability, and Safety

The accuracy and reliability of generative AI systems are crucial, especially in healthcare, where errors can have life-altering consequences.

Professor Magrabi revealed that "most of the safety issues with AI systems in real-world clinical settings are from poor data being fed into AI systems". This "garbage in, garbage out" principle emphasises the critical need for high-quality data for training AI models.

She also emphasised clinicians' responsibility to use AI safely and effectively. Clinicians must understand AI systems' limitations and verify their outputs before making critical decisions.
