Big Data in Healthcare: Revolutionizing Patient Care
Introduction In the rapidly evolving landscape of healthcare, big data has emerged as a transformative force, enabling unprecedented insights into patient care, disease management, and operational efficiency. Defined by its volume, variety, velocity, and veracity, big data encompasses vast datasets from electronic health records (EHRs), wearables, genomic sequencing, and more, generating over 2,314 exabytes daily by 2025. This chapter explores how big data is revolutionizing patient care, from predictive analytics to personalized medicine, while addressing benefits, challenges, and future trends. As of 2025, integrations of artificial intelligence (AI) and big data analytics are not only improving outcomes but also bridging gaps in access, with AI expected to accelerate markets like traditional, complementary, and integrative medicine (TCIM) to nearly $600 billion.
