Big Data Analytics for Healthcare Organizations a Case Study of the Iraqi Healthcare Sector

The rapid development of the healthcare industry has yielded a huge output of clinical, medical, and public health data with immense and complex structures that cannot be processed by conventional technologies. Therefore, new technology must be developed to handle such massive data sets, appropriately called "Big Data," for the analysis and discovery of hidden patterns. Big data analytics involves the discovery and the analysis of knowledge derived from the data to support decision making. In this paper, we present an overview the big data definition, characteristics, and the advantages of big data analytics in healthcare. We also examine the current Iraqi healthcare system and highlight the major challenges facing the healthcare sector that cannot be handled by conventional technology. In addition, we provide suggestions on overcoming these challenges via technologies using big data analytics. Consequently, we emphasize the value of employing big data analytics technology in the Iraqi healthcare sector. We address the main benefits and advantages that big data analytics can provide and propose a conceptual healthcare architectural framework based on big data technology to aid Iraqi healthcare organizations in shifting from traditional analysis to big data analytics. The proposed health architectural framework for the Iraqi healthcare sector, includes four components namely, raw data (data collection), data preprocessing, data analysis, and information presentation. The paper concludes with the expected advantages of utilizing the proposed architectural framework for Iraqi healthcare organizations and the recommended solutions to encourage healthcare practitioners in adopting big data technology.
