Screening for carbapenem-resistant Enterobacteriaceae: Who, When, and How?

Area of Science:

• Infectious Diseases
• Clinical Microbiology
• Public Health

Background:

• Carbapenem-resistant Enterobacteriaceae (CRE) pose a significant global health threat due to limited treatment options.
• Patient-to-patient transmission of CRE in healthcare facilities is often driven by inadequate screening protocols.
• While some institutions have implemented CRE screening, data on optimal approaches and comparative effectiveness are often lacking.

Purpose of the Study:

• To review the rationale behind various CRE screening policies.
• To discuss the performance characteristics of available laboratory methods for detecting CRE carriage.
• To inform the development of more effective surveillance strategies for CRE.

Main Methods:

• Literature review of existing screening policies for carbapenem-resistant Enterobacteriaceae.
• Analysis of performance characteristics of laboratory diagnostic methods for CRE detection.
• Discussion of factors influencing the implementation of surveillance programs.

Main Results:

• The optimal population, frequency, and methods for CRE screening remain debated.
• Resource limitations and lack of comparative data hinder widespread adoption of active surveillance.
• Various laboratory methods exist for CRE detection, each with distinct performance profiles.

Conclusions:

• Effective screening policies and robust laboratory methods are essential to control the spread of CRE.
• Further research and data are needed to define optimal surveillance strategies.
• Proactive screening can reduce CRE prevalence and prevent outbreaks in healthcare settings.
