Retail healthcare clinics are popping up everywhere, from strip malls, to grocery stores, to big-box retailers. In fact there are now over 1,400 stand-alone clinics across the country, or twice as many as five years ago. The number of urgent care facilities that treat more serious ailments and injuries has also blossomed to over 9,300 – that’s up from 8,000 in 2008 according to a report from the Washington Post.
