A review: Big data in healthcare challenges and application

Big data is a term defining collection of large datasets. In this paper, the objective is to discuss the characteristics and challenges of big data in which the process is to extract the information from large sets of big data. Healthcare System is the organization of people, institution and resources that deliver health care services to meet the health needs of target population. The digital transformation of healthcare can help to simplify, unify and streamline existing processes across the patient journey from patient admission, in-house care and post discharge management .Now there are many healthcare systems which help in hospitals for patient’s treatment but they cannot provide the interaction between the doctors. If there is a medical emergency due to some reasons like doctors are not available, so the patient moves from one place to another place. Recent research which targets utilization of large volumes of medical data while combining multimodal data from disparate sources is discussed. Potential areas of research within this field which have the ability to provide meaningful impact on healthcare delivery are also examined.
