A globally optimal understanding would involve far more than biochemistry and medical journals - population analysis, behavioral economics, regular economics, risk analysis, and a crystal ball would all be needed to avoid "doing a lot of things suboptimally". The fact that you haven't even mentioned those fields of study makes it clear you're not familiar with even the scope of the problem, let alone how to solve it. Hell, we could improve patient outcomes enormously by paying for everyone to receive basic dental care, today.
