Current trends and statistics show that technologies like Big Data and Machine Learning algorithms together used can change the way we process and analyze data. Both technologies can be said to be booming in a variety of industries. There are many aspects of Big Data and predictive algorithms based on Machine Learning that are recognized and being considered by researchers and technology consultants around the globe. Inspection of Big Data in healthcare shows a high level of opportunities that can be used to determine causal relationships between different healthcare components. This analysis can provide valuable relationships that can be used in IT transformation, practices and business value. In this paper we attempt to get an insight on different research that have been conducted by collaborating technologies like big data, machine learning and electronic health records. This collaboration can be used to bring many benefits in the field of healthcare. We breakdown the discussion into four sections beginning with the introduction, methodology, results and conclusion Index Terms-Big Data; HealthCare; EHR;.
