By 2030, the world will face a shortage of almost 14 million health care workers. In the United States alone, we’ll need as many as 35,000 more primary care doctors over the next decade. Without adequately trained health professionals, universal access to health care will remain out of reach and preventable illnesses and deaths will rise.

Fortunately, gloomy predictions are giving way to creative commitments, as countries expand their training programs, build cross-border partnerships to share skills, and deploy workers in new ways. What else should be done to defuse the health workforce crisis?
