Big analytics in the healthcare industry is emerging as a potential subject for extracting insights from massive data sets and better health outcomes and lowering costs. Its potential is huge, yet there are still challenges to face. The implementation of Big Data Analytics (BDA) in medicine will enable the application of innovations in both medical care and health monitoring. The purpose of this study is to investigate the potential applications of Big Data Analytics in healthcare. The study is founded on a critical review of the literature, as well as the presentation of chosen findings from direct research on the application of Big Data Analytics in medical institutions. It demonstrates that medical facility choices are heavily data-driven. Therefore, this review aims to provide an insight into the challenges that are faced by big data adoption for healthcare.
