Big Data in Healthcare: Transforming Patient Care and Operational Efficiency

Introduction

Big data in healthcare refers to the vast volumes of structured and unstructured health-related information generated from various sources like electronic health records (EHRs), medical imaging, genomic sequencing, wearable devices, patient surveys, and clinical trials. The integration and analysis of this data enable healthcare providers, researchers, and policymakers to make more accurate, timely, and personalized decisions.

Importance of Big Data in Healthcare

Big data has the power to significantly improve patient care, streamline hospital operations, and advance medical research. By analyzing massive datasets, healthcare organizations can predict disease outbreaks, optimize treatments, and reduce operational costs.

Key Applications of Big Data in Healthcare
