What term describes the analysis of large, complex health data sets to improve patient care, support personalized medicine, and reduce costs using AI and machine learning?

• A. Neural Implants
• B. Blockchain
• C. Interoperability
• D. Big Data Analytics

Answer: (D)

Big Data Analytics is the practice of analyzing large, complex health data sets to improve patient care, support personalized medicine, and reduce costs by using AI and machine learning. It brings together diverse data sources—electronic health records, imaging, genomics, claims, and wearable sensor data—and applies advanced computational methods to uncover patterns, predict outcomes, and guide decision-making. This enables targeted interventions, risk stratification, and more efficient resource use, which can lead to better outcomes and lower costs. The other terms don’t fit this description: neural implants refer to hardware devices inside the body, blockchain is about secure ledgers for transactions, and interoperability is about systems being able to exchange data, not the analytics process itself.
