Big Data Analytics: Health Care Industry

Big data has influenced many industries. One area that has been greatly influenced is the health care industry. This post describes how big data is influencing personal genomics in the health care industry. This post also evaluates how analyzing an individual’s genomes can aid in the foundation of predictive and preventive medicine.


Since its inception 25 years ago, the human genome project has been trying to sequence its first 3B base pair of the human genome over a 13 year period (Green, Watson, & Collins, 2015).  This 3B base pair is about 100 GB uncompressed and by 2011, 13 quadrillion bases were sequenced (O’Driscoll, Daugelaite, & Sleator, 2013).  With the advancement in technology and software as a service, the cost of sequencing a human genome has been drastically cut from $1M to $1K in 2012 (Green et al., 2015 and O’Driscoll et al., 2013).  It is so cheap now that 23andMe and others were formed as a consumer drove genetic testing industry that has been developed (McEwen, Boyer, & Sun, 2013).  At the beginning of this project, the researcher was wondering what insights the sequencing could bring to understanding decease, to the now explosion of research dealing with studying millions of other genomes from biological pathways, cancerous tumors, microbiomes, etc. (Green et al., 2015 and O’Driscoll et al., 2013).  Storing 1M genomes will exceed 1 Exabyte (O’Driscoll et al., 2013).  Based on the definition of Volume (size like 1 EB), Variety (different types of genomes), and Velocity (processing huge amounts of genomic data), we can classify that the whole genomic project in the health care industry as big data.

This project has paved the way for other projects like sharing MRI data from 511 participants, (exceeding 18 TB) to be shared and analyzed (Poldrak & Gorgolewski, 2014).  Green et al. (2015) have stated that the genome project has led to huge innovation in tangent fields, not directly related to biology, like chemistry, physics, robotics, computer science, etc.  It was due to this type of research that a capillary-based DNA sequencing instruments were invented to be used for sequencing genomes (Green et al., 2015).  The Ethical, legal and Social Implication project, got 5% of the National Institute of Health Budget, to study ethical implications of this data, opening up a new field of study (Green et al., 2015 & O’Driscoll et al., 2013).  O’Driscoll et al. (2013), suggested that solutions like Hadoop’s MapReduce would greatly advance this field.  However, he argues that current java intensive knowledge is needed, which can be a bottleneck on the biologist.   Luckily, this field is helping to provide a need to create a Guided User Interface, which will allow scientist to conduct research and not learn to program.  O’Driscoll et al. (2013), also state that the biggest drawback of using Hadoop MapReduce function is that it reduces data line by line, whereas genomic data needs to be reduced in groups.  This project, should, with time improve the service offering of Hadoop to other fields outside of biomedical research.

In the medical field, cancer diagnosis and treatments will now be possible due to this project (Green et al., 2015).  Green et al. (2015) also predict that a maturation of the microbiome science, routine use of stem-cell therapies could result from this.  These predictions are not far from becoming reality and are the foundation of predictive and preventative medicine.  This is not so far into the future that McEwen et al. (2013) have stated what are the ethical issues, for people who have submitted their genomic data 25 years ago, and they found data that could help the participants take preventative measures for adverse health conditions.  Mostly because clinical versions of this data are starting to become available like from companies like 23andMe. This information so far has yield genealogy data, a few predictive medical measures (to a certain confidence interval).  Predictive and preventative medical advances are still primary and currently in the research phase (McEwen et al., 2013).  Finally, genomics research will pave the way for metagenomics, which is the study of microbiome data of as many of the ~4-6* 10^30 bacterial cells (O’Driscoll et al., 2013).

From this discussion, there is no doubt that genomic data can fall under the classification of big data.  The analysis of this data has yielded advances in the medical fields and other tangential fields.  Future work, to expanding the predictive and preventative medicine is still needed; it is only in research studies, where the participants can learn about their genomic indicators that may lead them to certain types of adverse health conditions.
