The best sign that these innovations are beginning to go viral is that they have caught the attention of some giant businesses. Drugstore chains like Walgreens and CVS are now partnering with hospitals or accountable care organizations to give patients convenient points of access and to coordinate treatment. Companies that spend heavily on employee health care plans are learning the best lessons of the Obamacare laboratory. Walmart, the country’s biggest private employer, will fly workers who need transplants or heart or spinal surgery to premier facilities like the Mayo or Cleveland Clinics to assure that their problems get fixed right the first time, avoiding costly readmissions.

Obamacare has also had some important indirect consequences. According to Catherine Dower of the Center for the Health Professions at the University of California at San Francisco, since the Affordable Care Act states have become more aggressive about challenging some of the protectionist laws that prevent well-qualified medical professionals — pharmacists, nurse practitioners, physician assistants, emergency medical technicians — from offering some kinds of primary care. California just passed a law that will allow pharmacists to check your blood pressure and cholesterol level and to dispense prescription birth control and antismoking drugs. Letting pharmacists perform services that don’t require seven years of medical training makes those services cheaper and more convenient, increasing the chances consumers will take better care of themselves.
