Artificial intelligence is becoming increasingly integrated into healthcare, with the technology being explored for tasks ranging from medical research and disease detection to patient support and clinical decision-making.
While AI has the potential to improve healthcare delivery, researchers are raising important questions about how these systems can be made safer, more transparent and easier for healthcare professionals and patients to understand.
A recent review published in August 2026 examined some of the major challenges associated with the use of artificial intelligence in healthcare, including reliability, transparency, fairness, privacy and accountability.
Why Explainable AI Matters
One of the biggest challenges with some AI systems is that they can produce an answer or recommendation without clearly explaining how they reached it.
In healthcare, this can be particularly problematic.
A doctor may need to understand why an AI system has identified a patient as being at risk of a particular condition before deciding whether to rely on the recommendation.
Explainable artificial intelligence, often referred to as XAI, seeks to make AI decisions easier for humans to understand by providing information about the factors that influenced a system’s output.
This could help healthcare professionals evaluate AI recommendations rather than simply accepting them without question.
Accuracy Is Critical
Healthcare decisions can have serious consequences, making accuracy one of the most important requirements for medical AI.
AI systems can sometimes produce inaccurate or misleading information, particularly when they encounter unusual cases, incomplete data or situations outside the information on which they were trained.
A system that performs well under normal circumstances may therefore still require careful evaluation before being used in real-world healthcare settings.
Researchers have stressed the importance of testing AI systems extensively and monitoring their performance after deployment.
Protecting Patient Privacy
The use of AI in healthcare also raises concerns about patient privacy.
Medical records can contain highly sensitive information, including personal details, medical histories, diagnoses and treatment information.
As healthcare organisations increasingly adopt digital and AI-powered systems, protecting such information from unauthorised access and misuse becomes essential.
Strong data-protection measures, clear policies and responsible handling of patient information are therefore important components of trustworthy healthcare AI.
Addressing Bias and Inequality
Another concern is the possibility of bias in AI systems.
Artificial intelligence learns patterns from data, meaning that systems trained using incomplete or unrepresentative datasets may not perform equally well for everyone.
This could create disparities if an AI system is less accurate for certain populations, age groups or communities.
Researchers therefore emphasise the importance of using diverse and representative data when developing and testing healthcare AI.
Who Is Responsible When AI Gets It Wrong?
Accountability is another major issue.
If an AI system provides an incorrect recommendation that contributes to harm, questions may arise over who should be held responsible — the developer, healthcare institution or professional using the system.
Clear regulations and professional guidelines may be needed to establish how responsibility should be shared when AI is incorporated into medical decision-making.
Human oversight remains particularly important in situations where an AI recommendation could directly affect a patient’s health.
AI Should Complement Healthcare Professionals
Despite the concerns, researchers continue to see significant potential in artificial intelligence.
AI could assist healthcare professionals by analysing large amounts of information, identifying patterns and supporting certain administrative or clinical tasks.
However, technology should complement rather than replace professional judgement.
Doctors, nurses and other healthcare professionals bring clinical experience, communication skills and an understanding of individual patient circumstances that cannot always be replicated by an automated system.
Building Public Trust
For patients to confidently accept AI-assisted healthcare, they need to understand how the technology works and what its limitations are.
Healthcare institutions and technology developers may therefore need to provide clear information about when AI is being used, what data it relies on and how decisions are reviewed.
Transparency can help patients and healthcare professionals make informed decisions about whether and how to use AI tools.
The Road Ahead
The growing use of artificial intelligence in healthcare presents both opportunities and challenges.
AI could contribute to faster analysis, improved research and more personalised healthcare. However, these benefits will depend on ensuring that systems are accurate, secure, fair and understandable.
As the technology continues to develop, researchers, healthcare professionals, policymakers and technology companies will need to work together to establish safeguards that protect patients while allowing responsible innovation to continue.
Ultimately, the future of AI in healthcare should not be measured only by how advanced the technology becomes, but also by how safely, transparently and responsibly it can be used to improve patient care.
