“Networks and system development is my sweet spot,” said Dr. Klein, a pediatric cardiologist.
Dr. Klein said he was approached about the job last month by Mount Sinai Medical Center CEO Kenneth Davis.
“I've had a longstanding friendship with Ken Davis and have tremendous respect for his turnaround of Mount Sinai,” said Dr. Klein. “Ken realizes that the future will be very different from the past. We will have to respond with new metrics of care. It's almost a perfect storm.”
Mount Sinai's reach extends past New York City to Long Island and Westchester County through a network of physicians, 18 affiliated hospitals, five nursing homes and 12 physician group practices. Mount Sinai recently announced a clinical affiliation with Richmond University Medical Center on Staten Island and opened a large multi-specialty physician practice in Brooklyn Heights for outpatient services.
Dr. Klein is a former executive at two large hospital systems: the New York Presbyterian Healthcare System and the North Shore-LIJ Health System.
Most recently, Dr. Klein was dispatched by North Shore-LIJ to stop the flow of red ink at Lenox Hill Hospital, a recent North Shore acquisition. He was involved in administrative oversight of Lenox Hill as well as the Manhattan Eye Ear and Throat Institute, Staten Island University Hospital, and the Center for Comprehensive Care in lower Manhattan, which the system built after the closure of St. Vincent's Hospital. Dr. Klein had been North Shore-LIJ's Western regional executive director since 2011, but he joined the system in 2009 as senior vice president of children's services. He also was executive director of North Shore-LIJ's Steven and Alexander Cohen Children's Medical Center.
Aside from a period in Rhode Island when Dr. Klein was an associate dean at Brown University's medical school and a top executive at the Lifespan Corp. hospital system, he had spent most of his career and medical training—some 34 years—at New York-Presbyterian. He was chief operating officer of the system when he left in 2006.
"Dr. Klein is known as an innovator in the evolving health care landscape," Dr. Davis said in a statement. “With Dr. Klein's leadership, we will invigorate and integrate our growing network of hospitals, clinical practices and polyclinics."
Correction: Dr. Arthur Klein is not succeeding Wayne Keathley as president of Mount Sinai Hospital. Those facts were misstated in an earlier version of this article.
