📈 Big Data in Healthcare
Big Data in Healthcare refers to the massive volume, high velocity, and great variety of health information generated from sources like Electronic Health Records (EHRs), medical imaging, genomic sequencing, and wearable devices. The analysis of this data drives insights to transform care delivery.
The "Four Vs" of Big Data in Healthcare
Volume: The sheer amount of data (EHRs for millions of patients).
Velocity: The speed at which data is generated (real-time data from ICU monitors or wearables).
Variety: The different formats of data (structured text, unstructured images, genomics).
Veracity: The accuracy and trustworthiness of the data.
