"We do our work in the public interest, and really work hard to honor that," Greiner says. "The last few weeks have been very difficult…prompting us to review and assess and make sure that the policies that we currently have in place are very strong and that they help insure the integrity of what we do."
The Leapfrog Group
The Leapfrog Group, which represents employers and other large purchasers of healthcare services and health plans, has tried to improve quality of care through comparative measures. It publishes hospital safety scores that grade hospitals based on their track record for patient safety.
Denham was appointed to Leapfrog's Safe Practices Committee as Chairman in 2006. "The position represented a voluntary commitment with no financial or contractual relationship between Dr. Denham and Leapfrog," says a Leapfrog statement.
On Wednesday, Denham resigned his position from the committee "to make sure the present distraction does not impact you or the work you do." The group accepted his resignation on Thursday.
