The 2012 mHealth Summit near Washington, D.C., was all about the role of mobile technology in health care. Fool analyst Rex Moore was able to speak with Dr. Harry Greenspun, the senior advisor for health care transformation and technology at the Deloitte Center for Health Solutions. His new whitepaper, "mHealth in an mWorld: How mobile technology is transforming health care," looks at whether mobile technology really can help organizations do more with less. The key, says Greenspun, is "disruptive innovation."
