Power outages across New Jersey, New York and Pennsylvania forced some hospitals to evacuate and others to rely on backup generators in the wake of superstorm Sandy.
The powerful and massive storm, which reached the coast in southern New Jersey around 8 p.m. on Monday, is responsible for at least 35 deaths, the Associated Press reported.
One Manhattan hospital was forced to evacuate 300 patients hours after Sandy's landfall when backup power failed. Evacuation of the New York University Langone Medical Center was complete by late Tuesday morning, a statement from the hospital said.
Meanwhile, plans to evacuate about 200 patients from Coney Island Hospital were underway early Tuesday afternoon, said Evelyn Hernandez, a spokeswoman for New York City Health and Hospitals Corp., which owns the hospital. Backup power was restored on Tuesday to Coney Island Hospital after it lost power during the storm. Most patients who depend on ventilators or other devices were evacuated ahead of the storm, but seven critically ill patients remained at Coney Island Hospital and relied on battery-supported ventilators during the power outage. Those patients were transferred elsewhere Tuesday morning.
In New Jersey, Palisades Medical Center, North Bergen, began evacuating 83 patients Tuesday morning, said Donna Leusner, a spokeswoman for the New Jersey Department of Health. Flood damage knocked out power to Palisades Medical Center, said a spokeswoman with Hackensack (N.J.) University Medical Center, where Palisades patients were transferred by National Guard troops after 9 a.m. on Tuesday. Hackensack University Medical Center was expected to accept 51 patients from Palisades Medical Center, Nancy Radwin, an HUMC spokeswoman said.
Approximately 30 New Jersey acute-care hospitals were operating on backup generators after the storm, said Kerry McKean Kelly, a spokeswoman for the New Jersey Hospital Association.
Eight Pennsylvania hospitals experienced power outages and were operating on backup generators on Tuesday, the state Health Department said.
North Shore-Long Island Jewish Health System reported that Glen Cove (N.Y.) Hospital, Huntington (N.Y.) Hospital, Plainview (N.Y.) Hospital, Syosset (N.Y.) Hospital and its Stern Family Center for Rehabilitation, Manhasset, were operating on backup power, as was one campus of the two-campus Staten Island University Hospital in New York City.
Also, Staten Island University Hospital could no longer access electronic health records after flooding on Monday disrupted power to the building where data is stored. Doctors continued to use paper records on Tuesday.
Other hospitals lost access to EHRs during the storm. Doctors at West Penn Allegheny Health System in Pittsburgh reverted to paper and written orders as the storm came ashore and damaged a data center in Mountain Lakes, N.J. Dan Laurent, a spokesman for the system, said Allegheny General and Western Pennsylvania hospitals, both in Pittsburgh, and the emergency room at Forbes Regional Hospital, Monroeville, could not access electronic medical records between 8:30 p.m. on Monday and 4 a.m. on Tuesday.
