Winnie Abbott desperately wanted a knee replacement when she came to Dr. Jeffrey Angel’s office here in the foothills of the Ozark Mountains. Before Angel would operate, though, he had some requests for Abbott. She should take a class about the procedure and designate a family member to be her “coach” to help with recovery. And if she had problems after surgery, she needed to call a 24-hour number at Angel’s office rather than just go to the emergency room. This comprehensive approach to patients – focused not just on what happens in the doctor’s office but on how patients recover at home and how much their care costs – hasn’t always been the rule in American healthcare. But across the country, far from the vitriolic debate over Obamacare, it is driving a quiet revolution that is changing how doctors replace knees, communicate with patients, prescribe drugs, even deliver babies.
