BIG DATA for Healthcare: A Survey

Abstract

Recently, the massification of new technologies, which has been adopted by a large majority of the world population, has accumulated a tremendous amount of data, including clinical data. This clinical data have been gathered up and interpreted by medical organizations in order to gain insights and knowledge useful for clinical decisions, drug recommendations, and better diagnoses, among many other uses. This paper highlights the enormous impacts of big data on medical stakeholders, patients, physicians, pharmaceutical and medical operators, and healthcare insurers, and also reviews the different challenges that must be taken into account to get the best benefits from all this big data and the available applications. INDEX TERMS Big data, big data analytics, healthcare.

Big data analytics in healthcare: a systematic literature review

“…The concept of BDA overarches several data-intensive approaches to the analysis and synthesis of large-scale data (Galetsi, Katsaliaki, and Kumar 2020;Mergel, Rethemeyer, and Isett 2016). Such large-scale data derived from information exchange among different systems is often termed 'big data' (Bahri et al 2018;Khanra, Dhir, and Mäntymäki 2020). Although it is referred to as 'big' data, its importance is associated with its ability to capture small details about the subject being studied (George, Haas, and Pentland 2014;McAfee et al 2012).…”

“…The second approach to reviewing this body of literature has focused on summarising broad topics related to the use of BDA in healthcare. For instance, studies often attempt to summarise the sources of big data (Galetsi and Katsaliaki 2019;Kaur, Sharma, and Mittal 2018), the technologies used in the analysis of big data (Bahri et al 2018;Harerimana et al 2018), the benefits offered by BDA (Galetsi, Katsaliaki, and Kumar 2020;Kamble et al 2019), and the challenges involved in harnessing those benefits in healthcare (Amalina et al 2019;Mehta and Pandit 2018). We appreciate the valuable knowledge about the use of BDA in healthcare offered by these studies.…”

A Systematic Review of Healthcare Big Data

“…Healthcare BDA also helps the clinicians and policy makers to develop public policy and service delivery based on open health prescribed data, disease prevalence data, and economic deprivation data [102]. As per the authors in [100,101,103,104], the major areas for the applications of BDA in healthcare are as follows:…”
