Why is AI training data from overseas potentially unsuitable for Malaysian patients?

Question

Accepted Answer

Overseas-Trained AI May Not Be Suitable for Malaysian Patients Due to Significant Environmental Differences

Artificial intelligence (AI) tools developed and trained using patient data from regions like Europe or North America may not perform as effectively for Malaysian patients. This potential disparity arises because AI systems are sensitive to the environment in which they are trained, and significant differences exist between healthcare systems and patient populations in these overseas regions compared to Malaysia. Consequently, AI tools may exhibit biases or reduced accuracy when applied to a new, distinct demographic and clinical context.
Differences in Patient Demographics and Disease Patterns

The demographic makeup of patient populations, including age, ethnicity, and genetic predispositions, can vary considerably between continents. Furthermore, the prevalence and patterns of certain diseases also differ. For instance, common conditions in Europe or North America might be less prevalent in Malaysia, or vice versa, with unique local disease variations also existing. An AI system trained on data predominantly reflecting European or North American disease profiles may therefore struggle to accurately diagnose or predict conditions that manifest differently or are more common within the Malaysian population.
Disparities in Healthcare Infrastructure and Clinical Workflows

Healthcare infrastructure and established clinical workflows present another critical point of divergence. The technological capabilities of hospitals, the availability of certain diagnostic tools, and the standard operating procedures for patient care can differ substantially. For example, the types of imaging equipment used, the resolution of scans, or the typical steps a doctor takes when diagnosing a condition in Malaysia might not align with the data and processes used during the AI's original training. This misalignment can lead to the AI misinterpreting data or making recommendations that are not practical or appropriate within the Malaysian healthcare setting.
Potential for Bias and Need for Local Validation

When AI systems are trained on data that does not adequately represent the target population, they can inherit biases. If an AI tool was developed using data from a predominantly Caucasian population, it might perform less accurately for patients of different ethnicities common in Malaysia. This underscores the necessity for rigorous local validation. Medical physicists, with their expertise in quality assurance and performance evaluation, are crucial in assessing whether these AI systems function reliably and equitably within the specific Malaysian context before and during their clinical deployment.
