Not that this website is at all reputable but here is an excerpt from the very website you provided:
"How do Hospital CEOs get to where they are?
In studying this list of 20 New Hospital CEOs to Know, it seems that most of the CEOs have a couple things in common:
They served as COOs of hospitals before. COO, the Chief Operating Officer, delegates day to day operations and reports to the CEO, who is usually too busy to review production quotas and operations daily.
They held a Masters in Healthcare Administration, Business Administration or Nursing from an accredited university.
They held previous positions in strategic management, business and executive leadership. (Meaning medical expertise isnt all CEOs need to have!)
They had about 15 or more years of experience in healthcare before they became the CEOs of major hospitals. (Patience is a must.)
for goodness sake wired- please stop talking out of your arse about things you know nothing about."
as a side note, i think sublimazing's post makes the most sense (but im no expert).
