Ebola precautions in U.S. hospitals

Many hospitals, apparently, are going beyond the current evidence based recommendations to meet the Ebola threat.

From a recent Annals of Internal Medicine piece:

The CDC recommends placing patients with suspected or confirmed Ebola in a single-patient room and instituting contact and droplet precautions (1). These entail donning a fluid-impermeable gown, gloves, a surgical mask, and either goggles or a face shield. If the patient has “copious” secretions, the CDC also recommends shoe and leg coverings. If an aerosol-generating procedure is planned (such as intubation or bronchoscopy), the CDC recommends wearing an N95 mask and placing the patient in a negative-pressure room. Despite this guidance, many hospitals are planning to place all patients in negative-pressure rooms at all times, to compel all personnel to wear full-body hazardous material (HazMat) suits, and to require N95 masks or powered air-purifying respirators rather than surgical masks at all times...

Sharing airspace with an infected patient is not a risk factor. Transmission requires direct physical contact and is inefficient...

Exceeding these recommendations may paradoxically increase risk. Introducing new and unfamiliar forms of personal protective equipment could lead to self-contamination during removal of such gear. Requiring HazMat suits and respirators will probably decrease the frequency of provider–patient contacts, inhibit providers' ability to examine patients, and curtail the use of diagnostic tests.
