Non-susceptibility of Escherichia coli, Klebsiella spp., Pseudomonas spp., Streptococcus pneumoniae and Staphylococcus aureus in the UK: temporal trends in England, Northern Ireland, Scotland and Wales.

OBJECTIVES: To monitor and compare trends in the non-susceptibility of bloodstream isolates of pathogens to key antibiotics in the constituent countries of the UK between 2010 and 2014. METHODS: Routinely generated antibiotic susceptibility test results for bloodstream isolates of Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Pseudomonas spp., Streptococcus pneumoniae and Staphylococcus aureus were collected from hospital microbiology laboratories in each country. RESULTS: With the exception of a decrease in the proportion of S. aureus that were MRSA, non-susceptibility to key antibiotics among the pathogens studied remained largely unchanged over the 5 year study period, with any increases in non-susceptibility being small. Although some intercountry variation in the proportions of non-susceptible isolates was seen, apart from MRSA, the differences were generally small (<5%) and fluctuated from year to year, with no country showing consistently higher or lower rates of resistance. CONCLUSIONS: Collaboration between the constituent countries of the UK allows an integrated approach to nationwide surveillance of antibiotic resistance.

Using a simple point-prevalence survey to define appropriate antibiotic prescribing in hospitalised children across the UK.

BACKGROUND: The National Health Service England, Commissioning for Quality and Innovation for Antimicrobial Resistance (CQUIN AMR) aims to reduce the total antibiotic consumption and the use of certain broad-spectrum antibiotics in secondary care. However, robust baseline antibiotic use data are lacking for hospitalised children. In this study, we aim to describe, compare and explain the prescription patterns of antibiotics within and between paediatric units in the UK and to provide a baseline for antibiotic prescribing for future improvement using CQUIN AMR guidance. METHODS: We conducted a cross-sectional study using a point prevalence survey (PPS) in 61 paediatric units across the UK. The standardised study protocol from the Antibiotic Resistance and Prescribing in European Children (ARPEC) project was used. All inpatients under 18 years of age present in the participating hospital on the day of the study were included except neonates. RESULTS: A total of 1247 (40.9%) of 3047 children hospitalised on the day of the PPS were on antibiotics. The proportion of children receiving antibiotics showed a wide variation between both district general and tertiary hospitals, with 36.4% ( 95% CI 33.4% to 39.4%) and 43.0% (95% CI 40.9% to 45.1%) of children prescribed antibiotics, respectively. About a quarter of children on antibiotic therapy received either a medical or surgical prophylaxis with parenteral administration being the main prescribed route for antibiotics (>60% of the prescriptions for both types of hospitals). General paediatrics units were surprisingly high prescribers of critical broad-spectrum antibiotics, that is, carbapenems and piperacillin-tazobactam. CONCLUSIONS: We provide a robust baseline for antibiotic prescribing in hospitalised children in relation to current national stewardship efforts in the UK. Repeated PPS with further linkage to resistance data needs to be part of the antibiotic stewardship strategy to tackle the issue of suboptimal antibiotic use in hospitalised children.
