The Role of Data Science and Data Analytics in Healthcare
One of the complexity dimensions for healthcare is the massiveness of the data generated. In 2012, the estimated size of the data generated by worldwide digital healthcare was 500 petabytes (a petabyte is 1015 bytes or 1 million gigabytes). The growth of healthcare data size is projected to continue exponentially. By 2020, healthcare data is expected to reach the size of 25,000 petabytes (Sun & Reddy, 2013). Thus, healthcare sector indeed has the “Big Data” challenge. The ever-rising growth of healthcare data will serve no purpose unless it helps the sector. The essential question is “Can Big Data and data analytics used by healthcare help it learn from the past to become ‘smart’ in the future?” There is already a thought on moving from “treatment-based” practices to “outcome-based” practices. If people do not get the cure in spite of the large expenditures on IT in healthcare, then it is a losing battle for the sector.
