Application of Big Data Analytics in Health Care

Big data literally means large collections of datasets containing abundant information. Big Data is now rapidly expanding in all science and engineering domains. The current trend in Big Data analytics and in particular Health Information Technology is towards building sophisticated models, methods and tools for business, operational and clinical intelligence. The healthcare industry has generated large amount of data generated from record keeping, compliance and patient related data. In today’s digital world, it is mandatory that these data should be digitized. To improve the quality of healthcare by minimizing the costs, it’s necessary that large volume of data generated should be analyzed effectively to answer new challenges. It requires a technology that helps to perform a real time analysis on the enormous data set. This paper provides an overview of big data analytics in healthcare systems. It describes about big data generated by these systems, data characteristics and how big data analytics helps to gain a meaningful insight on these data set.
