A top emergency room doctor at a Manhattan hospital that treated many coronavirus patients died by suicide Sunday, her father and the police said.

Dr. Lorna M. Breen, medical director of the emergency department at NewYork-Presbyterian Allen Hospital, died in Charlottesville, Virginia, where she was staying with family, her father said in an interview.

Tyler Hawn, a spokesman for the Charlottesville Police Department, said in an email that officers on Sunday responded to a call seeking medical assistance.

“The victim was taken to UVA Hospital for treatment, but later succumbed to self-inflicted injuries,” Hawn said.

Breen’s father, Dr. Philip C. Breen, said she had described devastating scenes of the toll the coronavirus took on patients.

“She tried to do her job, and it killed her,” he said.

Philip Breen said his daughter had contracted the coronavirus but had gone back to work after recuperating for about a week and a half. The hospital sent her home again, before her family intervened to bring her to Charlottesville, he said.

Lorna Breen, 49, did not have a history of mental illness, her father said. But he said that when he last spoke with her, she seemed detached, and he could tell something was wrong. She had described to him an onslaught of patients who were dying before they could even be taken out of ambulances.

“She was truly in the trenches of the front line,” he said.

He added: “Make sure she’s praised as a hero, because she was. She’s a casualty just as much as anyone else who has died.”

In a statement, NewYork-Presbyterian/Columbia used that language to describe her. “Dr. Breen is a hero who brought the highest ideals of medicine to the challenging front lines of the emergency department,” the statement said. “Our focus today is to provide support to her family, friends and colleagues as they cope with this news during what is already an extraordinarily difficult time.”

Dr. Angela Mills, head of emergency medical services for several NewYork-Presbyterian campuses, including Allen, sent an email to hospital staffers Sunday night informing them of Lorna Breen’s death. The email, which was reviewed by The New York Times, did not mention a cause of death. Mills, who could not be reached for comment, said in the email that the hospital was deferring to the family’s request for privacy.

“A death presents us with many questions that we may not be able to answer,” the email read.

Aside from work, Breen filled her time with friends, hobbies and sports, friends said. She was an avid member of a New York ski club and traveled regularly out west to ski and snowboard. She was also a deeply religious Christian who volunteered at a home for older people once a week, friends said. Once a year, she threw a large party on the roof deck of her Manhattan home.

She was very close with her sisters and mother, who lived in Virginia.

One colleague said he had spent dozens of hours talking to Breen not only about medicine but about their lives and the hobbies she enjoyed, which also included salsa dancing. She was a lively presence, outgoing and extroverted, at work events, the colleague said.

NewYork-Presbyterian Allen is a 200-bed hospital at the northern tip of Manhattan that at times had as many as 170 patients with COVID-19, the illness caused by the coronavirus. As of April 7, there had been 59 patient deaths at the hospital, according to an internal document.

Dr. Lawrence A. Melniker, the vice chair for quality care at the NewYork-Presbyterian Brooklyn Methodist Hospital, said Breen was a well-respected and well-liked doctor in the NewYork-Presbyterian system, a network of hospitals that includes the Columbia University Irving Medical Center and the Weill Cornell Medical Center.

“You don’t get to a position like that at Allen without being very talented,” he said.

Melniker said the coronavirus had presented unusual mental health challenges for emergency physicians throughout New York, the epicenter of the crisis in the United States.

Doctors are accustomed to responding to all sorts of grisly tragedies, he said. But rarely do they have to worry about getting sick themselves, or about infecting their colleagues, friends and family members.

And rarely do they have to treat their own co-workers.

Another colleague said that Breen was always looking out for others, making sure her doctors had protective equipment or whatever else they needed. Even when she was home recovering from COVID-19, she texted her co-workers to check in and see how they were doing, the colleague said.
