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 […]

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 […]

October Issue: Infections in Acute Care, Understanding ‘Omics’ Sciences, Countering Vaccine Misinformation, More

“What we . . . may consider a passing moment in the course of our day—a short exchange with a family member, a few words of encouragement to a patient—might very well be a pivotal life event. . . . we must choose our words and actions carefully.”—editor-in-chief Shawn Kennedy, in her editorial, “It’s the Moments That Matter“

The October issue of AJN is now live. Here’s what’s new:

CE: Infection in Acute Care: Evidence for Practice

The author reviews the evidence on preventing and treating common infections in acute care settings, focusing on community- and hospital-acquired pneumonia, surgical site infections, and Clostridioides difficile infection.

CE: Knowledge of Precision Medicine and Health Care: An Essential Nursing Competency

This article provides a background in precision health care and the “omics” sciences—those that use genomic technologies to investigate the molecules in an organism’s cells—and discusses the implications for nursing practice, research, and education. […]

Multi-Drug-Resistant Organisms and Contact Precautions

When MRSA was new on the scene, strict isolation precautions were the norm.

Years ago, when we first started to see patients with methicillin-resistant Staphylococcus aureus (MRSA) infections at the hospital where I worked, we kept them in what was then called “strict isolation.” These patients were kept on one unit and cohorted in two rooms at the end of the hall. Staff wore gowns, gloves, masks, and hair covering. How we hated having to put on all that gear!

The current challenge of MDROs.

Today, we understand more about transmission, and isolation precautions are better tailored to the epidemiology of each drug-resistant organism. Unfortunately, though, since that time antibiotic resistance has rapidly increased, and we now find ourselves not only with a lot more MRSA to contend with, but with patients whose infections are susceptible to only one or two antibiotics (and occasionally, to none).

Some of these multi-drug-resistant organisms (MDROs) seem to be persistent colonizers—that is, the organism “takes up residence” on or in the body without causing infection, and can still be transmitted to others. In some cases these patients will need to be on isolation precautions every time they are admitted […]

What if Our Antibiotic Prescribing Practices are Wrong?

How often have you emphasized to patients, family, and friends that they must finish their prescribed antibiotics, even if they feel better? A provocative new analysis in BMJ takes a close look at why standard antibiotic protocols may promote, rather than prevent, antibiotic resistance.

The authors’ arguments center around two key points:

  • The length of a course of antibiotic therapy is not evidence based, but rather “set by precedent [and] driven by fear of undertreatment.”
  • Typical, prolonged courses of these drugs cause endogenous or colonizing bacteria to become antibiotic resistant. It is these “collateral” organisms, they argue, and not the organism that has actually caused the infection, that drive the spread of antibiotic resistance.

Individualized antibiotic courses.

The BMJ authors present a strong argument for more individualized courses of antibiotic treatment. Unfortunately, when the news media picked up this story, much of what was written and broadcast erroneously suggested that everyone should simply stop their antibiotics when they feel better. […]
