Hospital Admission Screening for CPO and C. auris Colonization
Receipt of health care abroad, and in certain U.S. regions where carbapenemase-producing organisms (CPOs) and Candida auris are more common, are risk factors for patients to be colonized with these organisms. Both CPOs and C. auris can cause asymptomatic colonization in patients that can lead to transmission in health care facilities if the appropriate infection control measures are not taken. Therefore, it is important to initiate hospital admission screening to rapidly identify and immediately implement infection control measures for residents or patients colonized with CPOs or C. auris, which is key to controlling the spread.

MDH Admission Screening Recommendations
MDH strongly recommends that, on admission, all Minnesota hospitals screen patients with the following exposures to detect both CPOs and C. auris:
- Overnight stay in a health care facility outside the United States or Canada in the previous 12 months.
- Ambulatory surgery or hemodialysis outside of the United States or Canada in the previous 12 months.
- Inpatient or skilled nursing facility stay in the previous 12 months in areas with documented transmission according to tracking data from the Centers for Disease Control and Prevention (CDC).
Case counts by state are available from CDC:
- CDC: Tracking Candida auris (updated monthly)
- CDC Antibiotic Resistance and Patient Safety Portal: Carbapenem-Resistant Enterobacteriaceae
On August 18, 2021, MDH sent a letter to Minnesota acute care infection preventionists to inform infection control programs of these recommendations and to increase awareness of the MDH Public Health Laboratory testing capacity.

Laboratory Testing
The MDH Public Health Laboratory (MDH-PHL) is one of seven labs in CDC's Antibiotic Resistance Laboratory Network (AR Lab Network) to receive funding support for enhanced capacity to detect and respond to emerging antimicrobial resistant threats, including CPOs and C. auris. One effort of the AR Lab Network is laboratory testing to detect colonization with CPOs and C. auris. The MDH-PHL supports colonization testing by:
- Providing health care facilities with specimen collection swabs and accompanying instructions
- Laboratory testing of swabs
- Reporting results quickly so that facilities can take action
Specimen Collection and Testing Information
CPO Screening
- Specimen source: Rectal swab using the Copan™ Transystem dual swab
- Testing method: Cepheid® Xpert® Carba-R assay
- This assay is FDA-approved and detects the five most common carbapenemases (KPC, NDM, OXA-48, VIM, and IMP) by PCR
- Turnaround time: Results are generally available in 1-2 business days
Candida auris Screening
- Specimen source: Bilateral axilla/groin skin swab using the eSwab™
- Testing method: Candida auris real-time PCR
- Turnaround time: Results are generally available in 1-2 business days
