Mayor Muriel Bowser is taking Providence Hospital to court, according to a D.C. official familiar with the matter.

The lawsuit, which has not yet been filed, will focus on the hospital’s plans to scale back acute-care services.

Providence plans to do that beginning Friday, but its ER will remain open. The hospital had its license renewed earlier this month. It was set to expire December 14.

The hospital originally planned to shut down both its emergency department and acute-care services this month, but it recently announced it would be delaying the closure of its emergency department until April 2019.

The hospital said on Monday that it will keep services to support the emergency room, like labs and respiratory care, but would shut down other acute-care services as planned. It says it will continue offering primary care and outpatient behavioral health services, as well as continue operating its Carroll Manor nursing facility.

At a rally earlier this week outside of the hospital, nurses said that residents east of the Anacostia River still need a “fully-functional hospital.”

Healthcare advocates say residents living in the eastern part of the District already have limited options for care; several hospitals are clustered on the western side of D.C.

“We are not satisfied with what Ascension is doing here. They are offering a small and I think dangerous hospital, potentially,” said Stephen Frum, a labor representative with National Nurses United, the union which represents nurses at Providence.

The emergency department that will remain open will be able to handle “low complexity cases,” said Johnny Smith, a spokesperson for Ascension, the organization which owns Providence Hospital.

“This includes treatment such as urgent and emergent care, low risk chest pain, sprains and strains, sore throat, cuts that may require stitches, cold and flu symptoms, and those that require no admission or a short stay. Those who cannot be attended to at our emergency department will be transferred to another facility,” he said in an emailed statement to WAMU.

WAMU has reached out to Ascension for comment on the lawsuit.
