5 The English Miracle 1 Introduction of targets Financial penalties Substantial changes in antibiotic use Cephalosporins and Quinolones β-lactam/β-lactamase inhibitors Cooke J, et al. Longitudinal trends and cross-sectional analysis of English national hospital antibacterial use over 5 years ( ): working towards hospital prescribing quality measures JAC 2015

6 % Isolates resistant The challenge of antibiotic resistant GNRs in the UK >3x increase in E. coli bacteraemia since 2004 Currently 36,000 cases / year Rates of resistance to key agents Gentamicin Ciprofloxacin Co-amoxiclav Piperacillin tazobactam.climbing alarmingly 46% of E. coli bacteraemia isolates now reported as co-amoxiclav resistant English surveillance programme for antimicrobial utilisation and resistance (ESPAUR) report E. coli - Co-amox K. pneumoniae - Pip-tazo

7 Some typical local data Some key rates of antibiotic resistance at this trust in 2016 E. coli cultured from urine Enterobacteriaceae cultured from blood Co-amoxiclav 27% 39% Ciprofloxacin 12% 19% Piperacillin-tazobactam 14% 16% Gentamicin 10% 14% At what rate of resistance would these drugs cease to be reliable clinically selected treatments? If you don t believe predictions of a world without antibiotics by 2050 Imagine working in your hospital without these antibiotics by 2020

8 Antibiotics also place individual patients at risk of resistant infection Explored relationship between prior antibiotic use and antibiotic resistance Reviewed 24 studies 19 Observational 5 RCTs >27,000 participants Urinary Infections Respiratory Tract infections

9 Forest plots of included studies Substantial Lasting Urinary Infection Respiratory Tract Infection 9

10 Option 1 - Don t start! Always begin broadspectrum intravenous antibiotics within the first hour! 10

11 Option 2

12 In reality focus rarely means stop >95% of Review and Revise Decisions are to continue antibiotic treatment With thanks to Dr Kieran Hand, Southampton

13 A time-line of stewardship in the UK

14 Why do we find stopping antibiotics so hard to do? Lack of knowledge of risks of prolonging treatment Prescriber etiquette Patient beliefs Complete the course

15 Do we know how long a course should be? Recommended course durations have fallen There is a lack of evidence that recommended durations are superior to antibiotic-sparing approaches* *w/exception of otitis media, Hoberman A et al New Eng J Med. 2016;375:

16 Complete the course to avoid resistance? Two paradigms of resistance selection 1940 s Fear Professional Pathogens Transmitted during disease M. tuberculosis Malaria HIV Resistance selected during treatment Resistance selected by inadequate treatment 21 st Century Reality Commensal Opportunist pathogens Transmitted in carrier state S. aureus E. coli K. pneumoniae Resistance selected as bystanders Resistance selected any antibiotic use. More use = more resistance

19 What is ARK-hospital? A 5-year applied research programme funded by NIHR The overarching aim of ARK is to reduce the incidence of serious infections caused by antibiotic-resistant bacteria in the future, through substantially and safely reducing antibiotic use in hospitals now Underlying hypotheses: In hospitals, most antibiotics are started appropriately; but there is reluctance to stop them once started Short durations of antibiotic treatment are sufficient to treat most genuine bacterial infections in hospitals Clinical review will identify those whose condition has not improved who need to continue taking them
