7 Factors Limiting Benefits of Big Data
Many experts have touted the use of Big Data in healthcare as one of the major hopes to improve care delivery and reduce costs. However, challenges remain, and a variety of them need to be resolved before Big Data can make an impact.

Even with de-identified data, there is the potential to identify patients, especially when data is associated with a narrowly defined population.
