Big data enables personalized treatment by which means?

• A. Standardizing care for all without variation.
• B. Reducing patient consent requirements.
• C. Eliminating trials.
• D. Analyzing diverse data to tailor treatment.

Answer: (D)

Big data enables personalized treatment by analyzing diverse data to tailor treatment. When we bring together information from many sources—electronic health records, genomic data, medical imaging, wearable sensors, claims data, and even social determinants of health—we can see how different patients may respond to a therapy, what risks they carry, and who is most likely to benefit. Advanced analytics and machine learning can identify patterns that point to the most effective option, the right dose, and the best monitoring plan for an individual, rather than applying a one-size-fits-all approach. This helps clinicians move toward precision medicine, where care is customized to the person’s unique biological and social context. The other ideas don’t fit personalization: standardizing care for everyone ignores individual differences; reducing consent requirements and eliminating trials misrepresent how data use and evidence generation actually work in practice.
