SEATTLE — Two more workers at Washington state’s largest psychiatric hospital have tested positive for the new coronavirus, bringing to five the number of people in the 850-bed facility who have acquired the disease, officials said Wednesday.

In the last week, another Western State Hospital employee and two patients were positive for COVID-19 and workers fear it will get worse due to conditions at the sprawling facility and the administration’s policies.

“I’ve been talking to workers at WSH about the situation there, and I’m afraid this could become another tragedy similar to what happened at Life Care Center of Kirkland,” said Justin Lee, a spokesman for the union that represents hospital employees, referring to the nursing home linked to 37 people COVID-19 deaths.

Like the Life Care Center, the psychiatric hospital is home to a vulnerable population that lives in close quarters; staff don’t have personal protective equipment like face masks; the administration was late to screen workers; and workers who were exposed to the disease are not being tested, Lee said.

“Staff continue to report to work because they care deeply about the patients, but they are also greatly concerned about management’s failure to be proactive with public health guidance,” Lee said.

At least 123 people have died from coronavirus in Washington state and almost 2,500 have tested positive. For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, or death.

Last week, the Department of Social and Health Services announced that two patients and one staff member tested positive for the virus. The employee had not worked during the incubation period, they said. .

One patient and the employee have both recovered, said DSHS spokesperson Kelly Von Holtz. The other patient remains in a Pierce County hospital. Anyone who visited the hospital between March 19 and 21 should monitor for symptoms, she said.

The hospital started screening workers on Friday. They closed most entrances to the buildings so workers file though a screening area in three entrances before starting their sifts. Tents were set up outside the doors to protect workers in inclement weather.

The hospital follows protocols for infectious diseases and has restricted patient and staff movement between wards, Von Holtz said.

But workers say the protocols fail to protect workers and patients.

One nurse found out from watching the news that she was exposed to COVID-10, Lee said. She had treated the first patient who tested positive.

“Thankfully, she went against management suggestions that she should return to work,” Lee said. “Some staff who have become ill after exposure to COVID-19 have been asked to return to work within 72 hours. Again, thankfully the worker I spoke to refused.”

Patients are sneezing and coughing throughout the wards, but staff are not provided the protective gear they need, Lee said.

The hospital screening process forces workers to congregate at the limited entrances, making social distancing difficult, said Nursing Supervisor Paul Vilja. The nurses who have been told to conduct the screenings are not provided protective gear and have not been trained on how to conduct a proper screening, he said.

The Lakewood facility has been the target of state and federal investigations for safety violations in recent years. It lost its accreditation and federal funding from the Centers of Medicare and Medicaid Services after it continually failed health and safety inspections.
