Ethical and Bias Considerations in Artificial Intelligence/Machine Learning.

As artificial intelligence (AI) gains prominence in pathology and medicine, the ethical implications and potential biases within such integrated AI models will require careful scrutiny. Ethics and bias are important considerations in our practice settings, especially as an increased number of machine learning (ML) systems are being integrated within our various medical domains. Such ML-based systems have demonstrated remarkable capabilities in specified tasks such as, but not limited to, image recognition, natural language processing, and predictive analytics. However, the potential bias that may exist within such AI-ML models can also inadvertently lead to unfair and potentially detrimental outcomes. The source of bias within such ML models can be due to numerous factors but is typically categorized into 3 main buckets (data bias, development bias, and interaction bias). These could be due to the training data, algorithmic bias, feature engineering and selection issues, clinic and institutional bias (ie, practice variability), reporting bias, and temporal bias (ie, changes in technology, clinical practice, or disease patterns). Therefore, despite the potential of these AI-ML applications, their deployment in our day-to-day practice also raises noteworthy ethical concerns. To address ethics and bias in medicine, a comprehensive evaluation process is required, which will encompass all aspects of such systems, from model development through clinical deployment. Addressing these biases is crucial to ensure that AI-ML systems remain fair, transparent, and beneficial to all. This review will discuss the relevant ethical and bias considerations in AI-ML specifically within the pathology and medical domain.
