Enhanced detection of Candidozyma auris colonization with universal screening on admission

Area of Science:

• Infectious Diseases
• Public Health
• Medical Microbiology

Background:

• Candida auris (C. auris) is an emerging multidrug-resistant fungal pathogen causing significant healthcare-associated infections.
• Effective screening strategies are crucial for controlling C. auris transmission in healthcare settings.
• Current public health screening criteria may not capture all colonized individuals.

Purpose of the Study:

• To evaluate the prevalence of C. auris colonization in a hospital setting through universal admission screening.
• To assess the proportion of colonized patients who meet existing public health screening criteria.
• To inform the development of more inclusive C. auris screening protocols.

Main Methods:

• Prospective study involving universal admission screening for C. auris.
• Data collection on patient demographics, clinical history, and screening results.
• Analysis of colonization rates and comparison with public health screening criteria.

Main Results:

• C. auris colonization was identified in 25 out of 22,742 screened patients (0.1% prevalence).
• A significant majority (80%) of colonized patients did not meet established public health screening criteria.
• This suggests limitations in current risk-based approaches for C. auris detection.

Conclusions:

• Universal admission screening can detect C. auris colonization missed by standard criteria.
• Existing risk factors are insufficient to identify the full spectrum of patients colonized with C. auris.
• Revised screening strategies are needed to improve early detection and containment of C. auris.
