Abstract: Health care is a data-rich industry. Administrative databases hold a tremendous number of transactions for each patient treated. The expansion of the adoption of electronic health records due to the Health Information Technology for Economical and Clinical Health (HITECH) provision of the American Recovery and Reinvestment Act is increasing the amount of data available exponentially. Still, the health care industry has been slow to leverage the vast data to improve care and health care operations. The adoption of value-based purchasing programs by Medicare and commercial payers along with increased demand for accountable care organizations motivated by the Affordable Care Act are moving both providers and payers to use data to improve operations. Health care's big data has the potential to revamp the process of health care delivery in the US and inform providers about the most efficient and effective treatment pathways. Value-based purchasing programs are incenting both health care providers and insurers to investigate new ways to leverage health care data to measure the quality and efficiency of care. The use of analytics in health care data presents of a number of daunting challenges, but also rich opportunities.
