Thank you for the question.
One area we've been focusing on, in which research is starting to show quite dramatic results, is the efficacy of certain tests. Tests are widely used in this system. There's evidence that they're overused and that they're frequently not effective and are very costly. So understanding which tests are required and under what circumstances is extremely important. Personalized medicine, which is really about tailoring the application of medical interventions to the individual's particular circumstances—their genetics as an example—again is a way of making sure that the interventions are targeted, effective, and not wasteful.
