Texas nurses: We had no Ebola protocols

Nurses at the Texas hospital where a Liberian Ebola patient died last week complain they were given few rules and little guidance on how to treat the severely ill man, contrary to assertions by US health authorities.

The head of the US Centers for Disease Control and Prevention (CDC), Thomas Frieden, said earlier this week that a "breach in protocol" by health workers led to a nurse becoming infected with the potentially fatal virus.

But a national union speaking late on Tuesday on behalf of the Texas nurses rejected the assertion that protocols were breached.

They told reporters at a telephone news conference that clear treatment guidelines for Ebola were all but non-existent at the Texas hospital.

"The CDC is saying that protocols were breached, but the nurses are saying there were no protocols," said Roseann DeMoro, head of the group National Nurses United, in a phone conference from California.

The nurses' union shared the revelations from workers at Presbyterian Hospital Dallas without disclosing their names, because many were afraid that their candour could cost them their jobs.

The first time that the patient came to the hospital he was sent back home, despite having told nurses that he had been in Ebola-stricken Liberia - information that authorities now say should have been a clear tip-off that he could be infected with the illness.

When the patient, Thomas Eric Duncan, returned a few days later, feverish and visibly ill, he was made to sit for hours in an emergency room waiting area, exposed to other patients.

The nurses said that after he was admitted, there were no guidelines on how to discard the Liberian patient's soiled towels and linens.

Duncan during much of his hospital stay was overcome with bouts of vomiting and diarrhoea, and the nurses said they had received no clear-cut guidelines about how the toxic mess would be cleaned off the floor, or who would do it.

After Duncan's death, authorities confirmed that Nina Pham, a nurse at the hospital who took care of him after he was admitted to the hospital, has been infected with Ebola.

A newly-minted nurse with just a couple of years' experience under her belt, Pham cared for Duncan for more than a day but is not aware of any problem with her protective gear, DeMoro said.

Still, she somehow became infected and is being treated for the illness at the same hospital where she contracted the disease.
