So the 71-year-old, a retired executive assistant who loved cooking casseroles, watching “Judge Judy” and listening to The Pointer Sisters, waited one hour for a nurse-ordered ambulance, according to call recordings and court documents. Two hours. Three hours. Four hours, phoning 911 back several times and telling the Fire Department about a heart condition. Ten hours. By the time an ambulance arrived at Hogan’s building, it was the middle of the night and she wasn’t answering her phone. The ambulance left without her. Weeks later, her body was found decomposing on the floor of her bedroom. It’s not clear Hogan’s wait is what killed her, but her estate has sued and her experience raises questions about Seattle’s relationship with its for-profit ambulance contractor, American Medical Response, which also provides the city’s 911 nurse line. “More checks and balances and accountability need to happen,” said Josephine Ensign, a professor emeritus at the University of Washington School of Nursing who called Hogan’s case concerning and upsetting. “Seattle can do better.”
