Any doctor that deviates from that plan would be penalized by the government. That means, for example, that a local doctor who knows the patient and his family, and who is aware of specific local circumstances affecting that patient will no longer be able to apply any of that knowledge in treating the patient.
And don't forget: The U.S. government is largely controlled by the pharmaceutical companies, and that means these health care dictates are almost certain to emphasize pharmaceutical treatments, disease "screening" and disease mongering provisions designed to sell more drugs.
