Blackwelder also thinks a team approach would be more productive in health care practices -- something many hospitals are already trying to adopt.
"In Kingsport, Tennessee, where I work, I'm happy to see patients, but we also have a health department or retail clinics that people could go to for their flu shots or other treatments," Blackwelder said. "And if we maintained good communication with those other providers we could also avoid duplication of services and increase our overall effectiveness."
Qualified nurse practitioners might also be able to lighten some of the primary care physicians' load, as would physician assistants if such practices are allowed. But in some states that are already desperate for doctors, such as Mississippi, nurse practitioners must legally practice under the guidance of a physician.
Other solutions could include opening more residency slots for doctors. Blackwelder said he'd also love to see universities discount tuition for students who studied primary care.
"I'd love for them to say to a student, 'I hear you are interested in primary care,' and present them with a bill with only zeros on it," he said. "And then say to people who were going into a specialty, 'Here's your tuition bill,' with a number in front of all those zeros."
People were worried the health care system would be overwhelmed when Medicare and Medicaid started in the 1960s too, Kentucky Gov. Steve Beshear told CNN chief medical correspondent Dr. Sanjay Gupta, but the system adapted.
"I understand there is a sense of worry, and change can be scary, but our present system is broken," Blackwelder said. "We pay twice as much for our health in this country and have worse outcomes than other countries.
"We will have to start coming up with creative solutions to this problem -- ones that won't have to wait for an act from Congress."
