dc.description.abstract | OBJECTIVES: To describe an outbreak of carbapenemase-producing Enterobacterales CPE) in a COVID-19 intensive care unit and discuss key infection control measures enabling prompt termination of the cluster. METHODS: CPE were isolated from clinical specimens and screening swabs from intensive care patients with COVID-19 disease and from environmental screening. Whole genome sequencing analysis was instrumental in informing phylogenetic relationships. RESULTS: Seven clinical isolates and one environmental carbapenemase-producing Klebsiella pneumoniae isolate - all carrying OXA-48, CTX-M-15 and outer membrane porin mutations in ompK35/ompK36 - were identified with ≤1 single nucleotide polymorphism difference, indicative of clonality. A bundle of infection control interventions including careful adherence with contact precautions and hand hygiene, twice weekly screening for multidrug-resistant organisms, strict antimicrobial stewardship and enhanced cleaning protocols promptly terminated the outbreak. DISCUSSION: Wards caring for COVID-19 patients, including intensive care units, have an important focus on preventing transmission of SARS-CoV-2 to other patients and health care workers. Prolonged use of personal protective equipment is common with donning and doffing stations at the ward entrance, leaving health care workers prone to reduced hand hygiene practices between patients. Minimising transmission of other pathogens by careful adherence to normal contact precautions including hand hygiene, even during high patient contact manoeuvres, is critical to prevent outbreaks of multi-drug resistant organisms. Appropriate antimicrobial stewardship and screening for multi-drug resistant organisms must also be maintained throughout surge periods to prevent medium-term escalation in antimicrobial resistance rates. Whole genome sequencing is highly informative for multidrug-resistant Enterobacterales surveillance strategies. | en_AU |
