It is one of health care's ironic — and unfortunate — twists: Women play dominant roles in making health care decisions for loved ones and providing care, but represent a miniscule percentage of top leadership across the industry.

Women make up 76 percent of the hospital workforce, according the Bureau of Labor Statistics. An analysis of BLS data by Rock Health also found that women account for 73 percent of managers in medical and health services, but just 4 percent of health care CEOs; 18 percent of hospital CEOs are women.

The reasons for this executive-level gender gap are varied, and have been pretty well documented over the years. Seven years ago, Piedmont Healthcare in Atlanta set out to close that gap. The organization formed the Women's Leadership Alliance, which aims to provide young women in the workforce with mentoring and leadership training. There's been some movement, but not a full shattering of the glass ceiling.

I caught up with two Piedmont leaders at an ACHE conference a couple of months ago to talk about the alliance and creating a more diverse C-suite.
