North Carolina Healthcare-Associated Infections Prevention Program 2013 Activities to Help Detect and Prevent the Spread of CRE

Carbapenem-resistant Enterobacteriaceae
by Connie Jones, RN, CIC and Megan Sanza, MPH

Carbapenem-resistant Enterobacteriaceae (CRE) has been deemed an urgent public health hazard by the CDC. (Sources: Antibiotic Resistance Threats in the United States, 2013: http://www.cdc.gov/drugresistance/threat-report2013/pdf/ar-threats-2013-508.pdf and the 2012 CRE Toolkit – Guidance for Control of Carbapenem-resistant Enterobacteriaceae (CRE): http://www.cdc.gov/hai/organisms/cre/cre-toolkit/background.html )  With that in mind, the HAI Advisory Group recently formed two Task Forces to concentrate on the prevention and detection of CRE.  Some pertinent information regarding CRE infection is provided below followed by details for ongoing and planned activities to assess and reduce current prevalence in affected healthcare settings. 

Background:
CRE are a group of bacteria found in the gut.  They can cause a variety of diseases including pneumonia, UTIs, and serious bloodstream or wound infections.   CRE are resistant to commonly used antibiotics and occasionally to all available antibiotics, which makes them a serious threat to public health. 

Who is at risk?  
Patients who require devices like ventilators, urinary catheters, or intravenous catheters, and patients who are taking long courses of certain antibiotics are most at risk. CRE have been found among patients in both acute and long term care settings. 

How is it spread?
CRE bacteria are spread by person-to-person transmission, primarily in healthcare settings, through contact with those infected or colonized. Due to the movement of patients throughout the healthcare system, if CRE are a problem in one facility, then typically they are a problem in other facilities in the region as well.

How is it controlled?
Treatment is difficult, and not possible in some cases.  As a result, prevention and control measures are critical.  Standard practices such as hand washing, contact precautions, and communication of CRE status with transferring/receiving facilities can help prevent the spread of disease.

Healthcare Task Force

The Healthcare Task Force is composed of members from acute care, long term acute care, and long term care facilities and is focusing on the prevalence of CRE within the state and what actions can be taken to help educate healthcare providers concerning the importance of CRE prevention.  A webinar by Dr. Katie Passaretti was presented in August and a recording of the webinar may be found on the NCQC and SPICE websites. 

Three CRE prevalence surveys are being developed by the Task Force: one each for Infection Preventionists, acute care laboratories, and long term care facilities. These surveys will be distributed during the first quarter of 2014 and will solicit CRE information for 2013. Awareness and evaluation of CRE is increasing across the United States, and with that other states including Virginia, Oregon, and Michigan have also been implementing CRE surveys.  Some states have shared their questionnaires and/or results with North Carolina, and as such the 2014 NC State CRE surveys are being adapted in the context of successful assessments already completed by other states.  In general, responses seem to indicate a need for ongoing education on appropriate CRE practices and up-to-date prevalence data from both acute and long term care settings, with a focus on CRE-related facility transfer policies.

Laboratory Task Force

The CRE Laboratory Task Force is composed of members are laboratorians from acute care facilities and the NC State Lab of Public Health.  It is tasked with determining the best method(s) for CRE detection and notification. This group is formulating guidelines and algorithms for North Carolina Laboratories on testing for CRE. The guidelines will be general enough that both large and small healthcare laboratories can implement them.  The guidelines will include a definition of CRE as well as procedures for testing, verifying, and reporting the results.  An algorithm which outlines the identification process is also being developed.  The sub-group is reviewing each automated system used for CRE testing and writing the guidelines to accommodate the most commonly used systems.
