Introduction: Carbapenemase-producing Enterobacteriaceae (CPE) are increasingly identified in Australian healthcare facilities. In 2015, guidelines for management were released by the Victorian Department of Health and Human Services, including definition of ‘transmission risk areas’ (TRAs) where local transmission of CPE has occurred, and recommended screening practices. We report program requirements and yield of CPE screening in 2 wards.

Method: TRA classification was applied to 2 wards (ICU, Rehabilitation) following clusters of IMP-4-producing Enterobacter cloacae complex in 2017. Two project nurses (combined 1.0 EFT) were assigned to implement contact-tracing, maintain a CPE database, educate staff/patients, and perform point-prevalence (PPS) and look-back screening. Look-back screening consisted of identifying surviving patients cared for in the defined wards during periods of potential CPE exposure, notifying the patients and placing electronic alerts for isolation/screening.

Results: For the ICU, 980 patient contacts (7-month period) were identified. Of these, 522 were screened and 2 additional CPE cases were identified (0.4% positive). For the Rehabilitation ward, 69 patient contacts (2-month period) were identified. Of these, 55 were screened and 1 additional CPE case was identified (1.8% positive). PPS in affected wards did not identify additional CPE transmission. Additional resources were required to facilitate screening, education and microbiological testing.

Conclusion: In the setting of local CPE transmission, we observed a low prevalence of CPE colonisation in our acute and sub-acute wards. Despite this, screening of high risk patients requires a standardised strategy with dedicated resources, and is fundamental in managing CPE transmission according to current Victorian guidelines.
