nurses not having it...,

nationalgeographic |  In a poll of 400 National Nurses United members released Wednesday, 60 percent said their hospital is not prepared for the Ebola virus, and more than 80 percent said their hospital had not educated them about Ebola or communicated any policy regarding potential patients infected with the virus.

Nearly one-third of the nurses said their hospitals lacked sufficient supplies of face shields and fluid-resistant gowns needed to protect them against the virus.

The union, which staged a "die-in" Monday on the Las Vegas strip to call attention to their Ebola concerns, blamed a lack of information and proper systems—rather than human error—for the decision last week to let Duncan leave the hospital when he first turned up complaining of fever and abdominal pain and mentioned his recent trip to Liberia. He was sent home but was readmitted on Sunday, much sicker.

It's not clear why the information about his recent travels did not raise a red flag in the emergency department, and why he was not suspected of having Ebola.

In a prepared statement in response to questions about the nurses' concerns, the American Hospital Association released a statement from Ken Anderson, the chief operating officer for the organization's Health Research and Educational Trust.

"We strongly recommend that hospitals follow CDC guidance in identifying potential Ebola patients," the statement said. "While in the Dallas case the hospital has acknowledged that it had a regrettable lapse in communication, the AHA is redoubling our efforts to make sure hospitals are aware of the latest CDC guidance, including checklists and screening criteria."

Frieden described the missed opportunity to catch Duncan's disease earlier as a "teachable moment," and said the CDC is redoubling its efforts to provide clear and useful information to hospitals about the Ebola risk.

"Essentially, any hospital in the country can safely take care of a patient with Ebola," he said, by providing a private room and bathroom, and by "rigorous, meticulous training" of staff. But Frieden acknowledged that the CDC is still working through the challenge of how to safely dispose of medical waste from Ebola patients.
