Making Sense of Interim CDC Guidance on N95 vs. Surgical Masks for COVID-19

Surprising new CDC guidance.

By Betsy Todd, MPH, RN, nurse epidemiologist and AJN clinical editor. Published: March 13, 2020. New posts will appear on this blog about aspects of the pandemic as the situation and our knowledge about the virus continue to evolve.

For nurses, the biggest news this week wasn’t the declaration of the COVID-19 epidemic as an official pandemic. It was the CDC’s release on March 10 of new interim infection prevention and control recommendations for COVID-19.

Many of us were taken aback to read the new document, which recommends the use of regular surgical face masks instead of N95s and the routine placement of patients suspected or confirmed of having COVID-19 infection in private rooms with the door closed instead of housing them in a negative pressure isolation room (which are always in short supply).

Unfortunately, without first acknowledging the concerns such a change from longstanding infection control practice might occasion among nurses and others, the CDC presented it as necessary due to an N95 shortage, stating, “When the supply chain is restored, facilities . . . should return to use of respirators for patients with known or suspected COVID-19.”

While it’s clear the CDC could have crafted this message more carefully, are caregivers being thrown […]

Is Your Facility’s Computer System a Patient Safety Risk?

Discussed in this post: “How Often Do EHRs Result in Patient Harm?” (AJN, News, March).

When we first had computers in the hospital—that is, while we still charted on paper but had quick online access to lab, radiology, and pathology results and could easily look up a patient’s prior admission history—it was wonderful. No more little lab slips floating all over the nurses’ station. No more unit-to-unit searches trying to figure out who last had custody of the patient’s X-ray films. (How could objects so large be so easily lost?)

A rocky transition to EHRs.

electronic health recordsThe transition to almost fully digital charting, on the other hand, has been pretty much a nightmare from the beginning. Nursing was rarely included in initial needs assessments. Many rollouts were chaotic, without additional staffing for the inevitable glitches that are bound to occur. Training of frontline clinical staff has been routinely minimal; we seem to be expected to pick up the many fine points of new software by some kind of digital osmosis.

That elusive clinician friendly EHR.

It’s very clear at this point that electronic health records (EHRs) were designed primarily for data collection and billing purposes. I have yet to see a system that could in any way be called […]

If I Want to Wear a Face Mask to Prevent COVID-19, Why Shouldn’t I?

By Betsy Todd, MPH, RN, nurse epidemiologist and AJN clinical editor. Published. March 6; updated March 12.

Times are uncertain. We don’t know how the spread of the new coronavirus will play out, or what parts of the country will be affected next. Many people continue to insist that wearing a mask in public places is “added insurance” against infection. But the reasons for NOT wearing a face mask far outweigh the purported benefit of keeping your nose and mouth covered when you’re out and about.

First, some background.

Health care workers use two main kinds of mouth and nose protection: either a regular surgical face mask, or an N95 respirator.

The purpose of a surgical mask is to prevent the wearer’s respiratory secretions from contaminating other people or surfaces. This is an example of “source control” in preventing infections. It is the reason the surgical team wears masks during operations and other invasive procedures.

N95 respirators look very much like face masks. They are designed to protect the wearer from inhaling hazardous particles (infectious agents, dust, etc.). Health care workers wear these when caring for people with COVID-19 or other serious respiratory infections.

But at least a face mask provides a physical barrier. Why shouldn’t I wear […]

Defining Death

My first encounter with brain death was back in the early 1970s. I was a new RN in a shock-trauma unit. We admitted a 17-year-old young woman who had attempted suicide by jumping out of a fifth-floor window. If it wasn’t awful enough, I remember it was Thanksgiving weekend and she had been home from college.

As one might imagine, she sustained massive injuries, including severe head trauma. She had been intubated at the scene and was on a mechanical ventilator. Her pupils were fixed and dilated, and she had no spontaneous respirations and virtually no brain activity, according to electroencephalography (EEG) studies.

A gradual refinement of criteria.

I recall that there had to be three consecutive EEGs done before we could remove the ventilator. There was no ethics committee or formal meetings with hospital attorneys or administrators—just the physician, the family, and the pastor. And then the patient’s siblings and grandparents came to say goodbye. It was heart-wrenching.

Things have gotten more defined and […]

COVID-19 for Nurses: Skip the Rumors and Stick to the Basics

(Published: February 28. Editor’s note: much information in this post is now dated and the post should be read only as a response to a particular moment in time. COVID-19 is now officially a pandemic and has rapidly spread worldwide. While rumors and misinformation were, sadly, already very much in play when this was written, and the overall tone of this post was neutral and descriptive according to our knowledge at that current moment, the post only remains live for archiving purposes. Our most recent posts on the crisis can be found here.)

In the U.S. at the time of this writing, the major risk presented by the current novel coronavirus (COVID-19) is not from the disease itself but from misinformation. Rumors, misinterpretations, and conspiracy theories are being transmitted at a rate far greater than that of the coronavirus itself. While the situation is evolving rapidly and things can change quickly, our understanding of the illness has also grown in a remarkably  short period of time.

So, is this a pandemic?

In an NPR interview this week, WHO director-general Tedros Adhanom Ghebreyesus said the term is used to suggest that the spread of a new infection is out of control and doing significant damage worldwide. We are not quite there yet. COVID-19 transmission in China appears to have plateaued, and, while the virus has been detected in numerous other countries this week, several countries have also been successful in controlling the spread of COVID-19 within […]
