Healthcare big data streams from multiple information sources at an alarming volume, velocity, and variety. The challenge that faces the healthcare industry is extracting meaningful value from such sources. This chapter investigates the diversity and forms of data in the healthcare sector, reviews the methods used to search and analyze these data throughout the past years, and the use of machine learning and data mining techniques to mine useful knowledge from such data. The chapter will also highlight innovations of particular systems and tools which spot the fine approaches for different healthcare data, raise the standard of care and recap the tools and data collection methods. The authors emphasize some of ethical issues regarding processing these records and some data privacy issues.
Chapter Preview


Medical data are at once the most rewarding and challenging of all biological data. For decades everyone was infatuated by the liability of keeping every record and collecting any possible information about everything in their life. The healthcare industry has also experienced these practices about generating and keeping large amounts of data driven by record keeping at physicians’ clinics, which is referred to as patient records. This includes forms filled by the patient regarding his/her personal information and oral examination recorded by physicians during visits. Other forms of checkups, different laboratory examinations, and CT scan as well as X-ray images are also kept in hospital’s emergency room when examining patients. Moreover, data about compliance & regulatory requirements, and patient care is also evolving from national and international organizations that monitor and administer the healthcare industry.

Electronic health records have experienced several studies. Drug safety study (Trifirò et al., 2009) investigated adverse drug reactions with other diseases, in (Jensen, Jensen, & Brunak, 2012), they combined the HER with the genetic data to reveal gene-disease association, (Almodaifer, Hafez, & Mathkour, 2011) discovered the interesting and concise medical rules for prediction purpose to assist the medical decision makers.

Medical diagnosis researches have proven a great success, because the data about the disease and the patient under examination is always available. In fact the medical diagnostic knowledge can be automatically derived from the description of cases solved in the past. (Kumar, Sathyadevi, & Sivanesh, 2011) proposed using an intelligent clinical decision support system to assist physicians in diagnosing. An automatic diagnosis system was presented in (Karabatak & Ince, 2009b). Soni & Ansari, 2011; Kharya, 2012; Huang, Chen, & Lee, 2007; (Ha, 2011) (Kononenko, 2001) summarized several machine learning techniques used for classifying diseases such as naïve Bayesian and neural networks, his work also highlighted the specific requirements for good performing machine learning algorithms in solving medical diagnostic tasks.
