Bellow, a cardiac surgeon at Montefiore Medical Center, leads a program that aims to keep patients recovering from heart surgery from having to be rehospitalized. A new study shows parts of New York have among the nation's highest readmission rates. To help, Montefiore opened a clinic last fall to check on patients' recovery a week after they go home, and patients wear a bracelet with a 24-hour phone number to call the cardiac unit at the first sign of problems.

In this Thursday, Jan. 17, 2013 photo, Michael Lee talks to a reporter about his recent heart surgery and follow-up care at Montefiore Medical Center in New York. Lee tuned out his care instructions when he left the hospital after emergency heart surgery, but when complications struck he called a new program at Montefiore Medical Center for help, that made it unnecessary for him to be readmitted. Missing out on critical patient education is a big reason that more than a million people a year are rehospitalized in the U.S., and hospitals are hunting innovative ways to fix that hole in health care.
