Risks and Challenges
AI in healthcare is not without risks and challenges that need to be addressed and managed. Some of the most important ones are:
Errors and injuries: AI systems are prone to errors, which eventually lead to patient injury or other significant problems. Errors can arise from faulty data, algorithms, or implementation. For example, an AI system that misdiagnoses a patient or prescribes a wrong treatment can cause harm or even death. Errors can also affect the quality and safety of care delivery, such as an AI system that fails to alert a provider of a critical condition or malfunctions during surgery.
Privacy issues: Privacy is a serious concern regarding patient data acquisition and AI inference. Data is the fuel for AI, but it also contains sensitive and personal information that needs to be protected from unauthorized access or misuse. Privacy issues can arise from data breaches, hacking, identity theft, or discrimination. For example, an AI system that leaks patient data to third parties or uses it for purposes other than intended can violate patient privacy and trust.
Inequality and discrimination: AI is not immune to bias, which can result in inequality and discrimination among patients or providers. Bias can stem from data, algorithms, or human factors. For example, an AI system that relies on data that is not representative of the population or reflects historical prejudices can produce unfair outcomes or decisions. Bias can also affect access to AI technologies or opportunities for learning and development.
Professional reshuffling: AI can change the roles and responsibilities of healthcare professionals, as well as their skills and competencies. Some tasks may be automated or augmented by AI, while others may require new forms of collaboration or supervision. For example, an AI system that performs diagnosis or treatment may reduce the workload of providers but also challenge their authority or autonomy. Providers may also need to acquire new skills such as data literacy or human-AI interaction.
Negative diagnosis: AI can have negative psychological effects on patients or providers, such as anxiety, stress, or depression. For example, an AI system that predicts a poor prognosis or a high risk of disease may cause fear or despair in patients or their families. Similarly, an AI system that monitors or evaluates the performance of providers may induce pressure or dissatisfaction.

Federated learning can enable data sharing without compromising privacy or security, as well as reduce bandwidth and storage requirements.
Edge computing:
Another challenge in developing effective AI models is processing large amounts of data in real time while minimizing latency and energy consumption. Edge computing is a technique that enables data processing at the edge of the network, closer to the source of data generation or consumption. Edge computing can enhance the performance and scalability of AI applications, especially for those that require low latency or operate in remote or resource-constrained environments.
Synthetic data:
A third challenge in developing effective AI models is ensuring that they are trained on diverse and representative data that reflect real-world scenarios and populations. Synthetic data is a technique that generates artificial data that mimics the characteristics and patterns of real data. Synthetic data can augment existing data sets, address data gaps or imbalances, and improve data quality and privacy.
