The U.S. is entering a "perfect storm" of rising demand for nurses, says Supplemental Health Care President and CEO Janet Elkin. The contributing factors are an aging nursing workforce, the addition of millions of newly insured patients and an aging baby boomer population. "Given that you'll have more patients and you don't want to increase (nursing) ratios, the only way you're going to do that is with more personnel. But finding them is not easy. With an average age of a nurse being 48 years old, it's going to be much more difficult," she said.
