"I look at it like a double helix. When the economy is up, the nursing supply goes down. And when the economy tanks, the supply goes back up," said Karen Haller, vice president of nursing at Johns Hopkins Hospital. "What we're seeing right now is an aging of the workforce. Many nurses in their 50s are going to be retiring soon. ... There is a silver tsunami of retirements coming. You can't delay retirement forever."
Ms. Haller of Johns Hopkins said the shortage will have disastrous effects without more trained nurses.
