Reforms crucial for sustainable care, experts say

On a recent work trip to China, Margaret Chan, director-general of the World Health Organization, said she hopes a well-trained family doctor will be available to provide medical services when she retires.

Chan, who is scheduled to leave her post in October 2017, said she will probably return to Hong Kong, where she was born and raised.

"A family doctor would help to take good care of my health and refer me to the right specialists at large hospitals, if necessary," she said.
