But, in a data-rich environment, there is no excuse for anything but thoughtful decision making, grounded in data.

Chapter 2 uncovered how this change in approach is transforming medicine. With the advent of the Data era, physicians are forced to rethink their opinion-based approach and adopt a data-based approach. This will likely lead to one of two outcomes:

  1. Doctors will make the adjustment, fully incorporating new sources of data in their decision-making. This will improve the quality and cost of medical care, while requiring physicians to expand their skills beyond just the practice of medicine.
