PCR Screening at a British Hospital Enables Timely Infection Control

At Royal Liverpool and Broadgreen University Hospitals NHS, the turnaround time for carbapenemase-producing enterobacterales (CPE) testing using culture and phenotypic confirmation was up to 72 hours. 

 

Because there was a lack of rooms to isolate the patients at the hospital, patients could be released before their test results were available. 

 

This delay increased the risk of the spread of CPE, resulting in the loss of beds and ward closures to prevent further spread of CPE. The cost of losing a single bed was £200 a day, amounting to £150,000 if a ward with 25 beds was forced to shut down for a month.

 

There was a critical need for a faster CPE screening method to eliminate the possibility of patients spreading CPE or being discharged before they received their test results.

 

In order to avoid delays and prevent the spread of CPE, the Royal Liverpool and Broadgreen University Hospitals NHS Trust implemented PCR-based CPE testing using the Xpert® Carba-R test on a GeneXpert® Infinity system to enable faster screening. The Xpert Carba-R test provides results in 50 minutes, significantly reducing the total turnaround time (TAT) from 72 hours to 4 hours. 

 

The expedited TAT allowed room bays to be decanted and decontaminated quickly, reducing the number of beds lost to CPE due to contamination measures by 50%.

 

"The introduction of rapid molecular testing for carbapenemase-producing enterobacterales allowed us to shorten the time to result to a matter of hours instead of days, identify patients quickly and take the necessary precautions quickly."
