The amount of bullshit I've seen in the hospital gives me little faith that any policy change will solve the problem.
The real solution lies in producing safe consumer usable technology that moves all diagnostics out of the hospital. When we can get our comp, CBC, liver enzymes all with a drop of blood on a 1$ chip, when everyone and their neighbors own low cost portable MRI machines, when we can all read our EKG right on our cellphones and have it be interpreted for us 24/7 holter monitor style. Then it would only takes a team of engineers to produce software to quickly crunch all the data to produce a picture of our health... and save everyone from that expensive trip to the hospital.
