A Systematic Review of Techniques and Sources of Big Data in the Healthcare Sector

Abstract: The main objective of this paper is to present a review of existing researches in the literature, referring to Big Data sources and techniques in health sector and to identify which of these techniques are the most used in the prediction of chronic diseases. Academic databases and systems such as IEEE Xplore, Scopus, PubMed and Science Direct were searched, considering the date of publication from 2006 until the present time. Several search criteria were established as 'techniques' OR 'sources' AND 'Big Data' … Show more

“…In the past decade, the variety and volume of health data sources have both increased dramatically, making traditional data management and analysis tools insufficient. Big data has emerged as a response to the growing need for health organizations to have new tools capable of processing massive amounts and varieties of healthcare data [30]. A major advantage of big data techniques is the use of advanced analysis techniques such as predictive analytics to improve clinical care, quality of care and patient outcomes.…”
