Solution for Expensive Hospital Cost?

In every country, it cost a lot to get a surgery or to get check up from the hospital. And a reporter from New York Times wrote his solution in his article.

The strategy is to move beyond doctors — to take the work of health care and shift down from doctors and nurses to lay people, peers and family.  In the United States and other wealthy countries, lay people can fill in the gaps in left by doctors’ care.  In poor countries, people with no or little formal medical training are successfully substituting for doctors and nurses.

 I see where he is going, but there is a really big problem with his problem. Those people with no or little formal medical training would not know how to deal with really serious disease, so they would not know how to treat those people, so they are going to end up dying. I think he needs to come up with more realistic solution for that problem.
