1 The Rise of Carbapenem Resistant Organisms
RUSI/STFC workshop on Antimicrobial Resistance 6th February 2013 Professor Mike Sharland Professor of Paediatric Infectious Diseases St George’s, University of London Chair of the DH advisory committee on Antimicrobial Resistance and Healthcare Associated Infections (ARHAI)

2 Carbapenem Resistant Organisms (CRO’s)
Extremely Resistant Gram Negative Bacteria Complex names – KPC, NDM, VIM, OXA – enzymes and bacteria Rapid global Spread Resistant to last decent antibiotic class – carbapenems (meropenem) With inadequate treatment can become pan-resistant

3 CRO – Serious Adverse Outcomes
Mortality 20-40% - associated with: Extended Hospital Stay Esp ICU Exposure to Invasive Devices E.g. Ventilators, Central Venous Catheters Comorbidities assoc with Advanced Age E.g. immunosupression, cardiac disease, chronic airway disease – also premature

4 Worldwide Distribution of Klebsiella pneumoniae carbapenemase producers

AMCLI-CoSA – Italian National CRE Surveillance 2011

9 AMCLI-CoSA – Italian National CRE Surveillance 2011

10 Israel’s KPC Outbreak and Intensive IPC Intervention

11 Antimicrobial Resistance spread into and within the UK
CRO colonized residents or visitors Hospital treatment or travel overseas Non-human reservoirs: foodstuffs (domestic or imported) Medical Tourism Elective & cosmetic Non-human reservoirs: animals and environment Military and civilian casualties from conflict zones Community Carriage? Inter-hospital transfers (UK)
