More than 200 hospital administrators, doctors, nurses, and others met with national experts at the Union League in Center City to learn about strategies to reduce hospital readmissions in the five-county Philadelphia area. "We have a lot of interesting innovative practices to share . . . and hopefully that can really accelerate the pace of change in addressing this problem," said Kate Flynn, president of the regional Health Care Improvement Foundation, which is leading the effort in partnership with Independence Blue Cross. The initiative is part of a third group: the Partnership for Patient Care, a joint project of Independence, the improvement foundation, and the hospitals.
