1) The document discusses how data-driven healthcare can improve medical diagnosis and treatment outcomes.
2) It provides two case studies of patients who received improved diagnoses and treatments once multiple data points were collected and analyzed together, rather than by individual specialists.

how bad it was. Researchers
gave the same data to 40
cardiologists and asked the
same question: “Should this
person have cardiac surgery or
not?” Half said yes and half said
no. Whether you get surgery
depends on which doctor you
happen to pick? That is pretty
bad. And that’s not the worst
part. Two years later they took
the same data to the same
cardiologists, and 40 percent
changed their mind. I could give
you 100 examples like that.”
