Running head: BIG DATA ANALYTICS 1 BIG DATA ANALYTICS 8 Big Data Analytics in Healthcare Name of the Student Instructor Institution Course Date The health care system is increasingly adopting the use of electronic health records. This has led to an increase in the quantity of clinical data that is available. As a result, big data has been adopted as a way of analyzing these large quantities of data. The main reason why big data technology has gained popularity is because it can be able to handle large volumes of data compared to the traditional methods(Wang et al., 2018). It also supports all kinds of data including the structured, semi-structured and unstructured. It also provides predictive model design and data mining tools and this makes the decision making process to be better. Big data framework allows for batch processing as well as stream processing of information. Batch processing makes the analysis of data within a specific period of time possible (Wang et al., 2018). On the other hand, stream processing is used for applications which need real-time feedback. Applications of big data analytics in health care leads to an improvement in the patient-based services as well as detection and control of spread of diseases. It also leads to new knowledge and intelligence as a result of the integration and analysis of data with different nature. Therefore, the use of big data analytics in the health sector has increased due to the need for improved medical services, faster analysis of information and accuracy, and cost reduction. The main role of the health care sector is to ensure that the population remains healthy. Therefore, there is need for better service delivery at all times. Big data analytics have enhanced the ability to provide the services to the patients in a number of ways. First of all, it has positively resulted to better image processing (Wang &Hajli, 2017). This has enhanced the processes of diagnosis, therapy assessment and planning. Medical images present the data that is used in all these processes. As such, big data analytics provides for an efficient way of storing the information because it requires large storage capacities in the long run. The demand for accuracy also makes big data analytics an efficient tool to use in the analysis of information related to image processing. Signal processing is another area in medicine that requires the use of big data analytics. This is because it results to production of large volumes of data which require being stored in high speeds from several monitors and different patients(Wang &Hajli, 2017). On the other hand, physiological signals also have a problem because of the spatiotemporal nature. This makes the analysis of such signals to be more meaningful when they are analyzed alongside the situat.
