The future of AI in healthcare research and practices is sure to bring forth even more potential uses. The possibilities are limitless, yet a few questions remain.
Ethical Considerations
The big question in AI research is how ethical it is. Any AI development is burdened with answering concerns about the potential unethical use that this new technology could bring.
Data privacy is one of the primary concerns. Healthcare AI needs an extensive amount of patient data to function effectively. This makes AI a prime target for malicious attacks from hackers or other nefarious parties.
Given these concerns, the secure safekeeping and ethical handling of patient data becomes imperative. Healthcare centres ought to prevent the mishandling of protected health information in any way possible. Failing to do so may result in grave breaches of patient privacy, which erodes public confidence in healthcare institutions.
Another issue would be the potential for bias in AI systems. Any previous biases in data may be preserved because AI applications in healthcare utilize algorithms that have been trained on past clinical data. This may lead to unequal treatment among different patient populations.
AI systems may, for instance, be more successful in treating or detecting illnesses in some demographic groups while providing less precise or efficient care in others. The unfortunate result of bias would be a spike in health inequities.
The perpetual use of AI in healthcare raises concerns about the role of human intelligence in clinical decision-making. A risk exists that over-reliance on AI could lead to a diminished role for healthcare workers, potentially eroding the vital human element in healthcare.
Regulatory Landscape In Europe and the USA
The ethical concerns that AI brings can only be addressed through robust legislation. Some states and regulations have been proactive in doing just that.

AI Regulations in the European Union
The European Union is already handling the implications of AI and the potential issues that may arise from it. The way the situation is being handled is by applying pre-existing legal frameworks and creating new regulations like the proposed AI Act, for example.
The EU General Data Protection Regulation (GDPR) is a means through which Artificial Intelligence is partly regulated and monitored, but not completely. The regulations have to deal with personal data pertaining to patients who are being treated by medical professionals. When it comes to AI, however, in the health systems, it is more focused on innovation.
Healthcare innovation is usually conducted a lot more through clinical trials than directly into patient treatment. Although GDPR protects patient data, it does not fully cover the information of research participants.
What the proposed AI Act introduced was a risk-based way to handle the consequences of medical AI based on the key principles of ethical AI. GDPR and the AI Act have to be combined and synchronized so that all the goals each puts forward can be achieved together.
GDPR places restrictions on automated decision-making (ADM) and the processing of health data, except in cases where patient consent is obtained or for public interest purposes.
The proposed AI Act aims to provide a technology-neutral definition of AI systems within EU law and introduce a classification system that assigns different requirements and obligations based on a risk-based approach.
AI Regulations in the United States
The FDA has not taken the same steps as the European Union to set up comprehensive regulation for medical artificial intelligence, but The Center for Devices and Radiological Health (CDRH) of the FDA is therefore considering a complete product lifecycle-based regulatory framework.
Such a framework would allow for real-time modifications and adaptability for these medical devices without limiting their effectiveness or risking their safety.
The FDA usually chooses an appropriate premarket pathway through which they are able to safely analyze medical devices and review them. Such pathways include the De Novo classification, premarket clearance (510(k)), and premarket approval.
The FDA has the authority to evaluate and approve modifications to medical devices, including software as a medical device, if the modification carries a significant risk to patients. This means that any changes made to medical devices or their software that could potentially impact patient safety must undergo review and clearance by the FDA.
The traditional manner in which the FDA regulates medical devices is not meant for adaptive artificial intelligence and machine learning technologies. The need for full-proof medical devices that have been changed and improved through AI and ML may actually require more devices to go through the FDA’s premarket review.
