Tuberculosis: Nurses Play Critical Role in Prevention, Diagnosis, Treatment

Mantoux skin test/CDC PHIL

In the U.S., the chances are that tuberculosis isn’t on your mind a lot. Most of us focus on TB only when we have a patient on airborne precautions—or when we’ve been exposed to TB at work.

Globally, TB was one of the top 10 causes of death in 2015. In the U.S., after a spike in cases early in the HIV epidemic, the incidence of TB has fallen to about three cases per 100,000 people. In TB-endemic countries, incidence rates run into hundreds per 100,000. But with TB elimination defined as a rate of less than one case per million people, we are far from eradicating this disease in the U.S. In fact, the number of TB cases in the U.S. rose slightly from 2014 to 2015.

Also, of course, nurses often work with people who are at high risk of acquiring TB—transplant recipients, others who are immunocompromised, people with HIV or certain cancers, those who are refugees or homeless—increasing our own risk for the disease as well. Therefore, the low overall U.S. incidence rate doesn’t reflect the experience (or risk) of most nurses.

August Issue Highlights: TB Screening, The Baby-Friendly Hospital Initiative, Antibiotic Stewardship, More

The August issue of AJN is now live. Here are some articles we’d like to bring to your attention.

CE Feature: Tuberculosis: A New Screening Recommendation and an Expanded Approach to Elimination in the United States

The U.S. Preventive Services Task Force (USPSTF) recently issued a new recommendation statement on latent tuberculosis infection testing that expands nurses’ opportunities to identify at-risk populations for tuberculosis prevention. This article provides a general overview of tuberculosis transmission, pathogenesis, and epidemiology; presents pre­ventive care recommendations for targeted testing among high-risk groups; and discusses the USPSTF rec­ommendation’s applicability to public health and primary care practice in the United States.

CE Feature: Beyond Maternity Nursing: The Baby-Friendly Hospital Initiative

The Baby-Friendly Hospital Initiative (BFHI) is a program developed by the World Health Organization and the United Nations Children’s Fund to promote breastfeeding in hospitals and birthing facilities worldwide. Since the program was launched in 1991, breastfeeding initiation, duration, and exclusivity have increased globally, a trend largely attributed to changes in hospital policies and practices brought about by the BFHI. This article provides an overview of these practices and policies, the insti­tutional benefits of achieving BFHI certification, and the process through which health care facilities can do so.

Nurses and Latent TB Infection

Are you “PPD positive”?

In December, a California maternity nurse was diagnosed with active tuberculosis. More than 1,000 people, including 350 infants, may have been exposed. In infants, tuberculosis can be hard to diagnose and is more likely than in newly infected adults to progress to active disease and to disseminate to extrapulmonary sites. Therefore, a course of isoniazid was recommended for each of these exposed infants, as well as for any parents, visitors, or staff who tested positive after the exposure.

Some of the details of this incident weren’t released to the media. In my experience, active infection in a health care worker who has not recently traveled to a TB-endemic area is almost always the result of reactivated latent infection. That was the case in a similar exposure more than 10 years ago, when a New York City maternity nurse exposed more than 1,500 infants and adults to active tuberculosis.

And in three of the largest TB exposure investigations on which I’ve worked, the index cases were nurses in oncology, transplant, and the ED whose latent tuberculosis infection progressed to active infection. In these three cases, neither the RNs nor their own primary care providers connected their persistent febrile respiratory infections with […]
