2 Overview Antibiotic resistance a critical patient safety and public health issuethe problem with resistant organismsthe link to antibiotic useAppropriate use of antibiotics in our hospitalAntimicrobial StewardshipAntibiotic Awareness Week 2012– Preserving the miracle – use antibiotics appropriatelyThis presentation will cover:The problem of antibiotic resistance todayThat it is a critical patient safety and public health issueHow extensive the problem isThe link between the antibiotic use and the development of resistance.The role of antimicrobial stewardship in supporting the appropriate use of antibioticsInformation on antibiotic awareness week in Australia and internationally and the focus on preserving the miracle of antibiotics while there is still time
3 Importance of antibiotics Most significant impact on life expectancy in last 100 years (arguably) – ability to prevent and treat infectionMajor factors: public health (sanitation), vaccination, antibioticsCrude mortality rates for all causes, noninfectious causes and infectious diseases over the periodThe most significant impact on increasing life expectancy in the last 100 years has been the ability to prevent infection through improvements in public health, such as sanitation, and vaccinations and to treat infection with antibiotics.Mortality rates from non infectious diseases has remained fairly constant whilst dying from infectious diseases has decreased markedly, although more recently this is starting to increase.1. Armstrong GL et al, JAMA 1999;281(1):61-66
4 Antibiotics and other medical advances Other advances rely on ability to control infectionTransplantationNeonatal careChemotherapy for malignancyImmunosuppressionSafe surgerySafe obstetric careIntensive care interventionsAdvances in modern medicines such as transplantation, neonatal care, cancer treatments, safe surgery and obstetric care and ICU interventions all rely on effective antibiotics to control infection. Without antibiotics these therapies will be endangered.
5 Emergence of antibiotic resistance Antibiotic resistance threatens ability to control infectionThe time it takes for bacteria to develop resistance is decreasing.Start of line = time of antibiotic discovery, End of line = when resistance reportedMore recently the time between discovery and development of resistance has become much shorterNote – why is the line for Vancomycin so long ? In many hospitals the use of Vancomycin has been restricted.2. Pray LA Insight Pharma Reports 2008, in Looke D ‘The Real Threat of Antibiotic Resistance’ 20125
6 Resistance spreads rapidly Once resistance develops it spreads rapidly. This graph from the Center of Disease Control in the US demonstrates how quickly resistant strains of MRSA, VRE and fluoroquinolone resistant Pseudomonas aeruginosa have spread.3. Centers for Disease Control and Prevention
7 Antibiotic resistance in 2012 Worldwide problems with resistant pathogens including MRSA, VRE, Gram negative organisms, HIV, TB and malaria4,5These problems affect us here in Australia tooLast line antibiotics (carbapenems, fluoroquinolones, 3rd-gen cephalosporins) may no longer be effective against some common bacteria e.g. multi-resistant E. coli infections causing cystitis5This slide summarise the state of antibiotic resistance in 2012.Worldwide there are problems with resistant pathogens such as MRSA, VRE, Gram negative organisms as well as HIV , Tb and Malaria.Australia is not isolated from these problems.There are concerns that last line antibiotics such as carbapenems, fluorquinolones and 3rd and 4th generations cephalosporins may no longer be effective against some common infections such as multi-resistant E coli urinary tract infections.Note: the report from the World Health Organisation provides a comprehensive summary of the global state of resistance, including in our region, and outlines some of the options to address the problem not only in human health care but in other areas.4.

8 Resistance in our region Gram negatives (E. coli, Klebsiella spp.)– common infections e.g. UTI in community– high rates resistance in our regionESBL-producing organisms = resistant to cephalosporinsResistance is high in our region with many countries having high levels of resistant Gram negative bacilli such as E Coli and Klebsiella species that cause common infections such as urinary tract infections.This slide shows the emergence of extended spectrum beta lactamase producing Gram negative bacilli in the Asia Pacific region. These organisms are resistant to cephalosporins.Australia – on first look it appears that we are doing quite well, however it is important to remember that:This slide does not give the full picture of resistance in Australia, Australia is still working on the development of a comprehensive surveillance system.This is an emerging and growing problem in AustraliaAs Australians continue to travel overseas it is likely that the rates will follow trends seen in other countries.6.

9 Antibiotic resistance locally Which infections are we seeing ?Insert hospital dataNumbers of casesExample casesNote: Users should insert local hospital data into this slide. If a hospital antibiogram is available, use that. If not, give examples of infections from resistant pathogens that have occurred. Examples might include: central line associated bacteraemia, catheter associated urinary tract infections, surgical site infections. Consider including information about increased length of stay and negative outcomes for patients.
10 Real people are affected No one is immune from the risk of infection with a multi-resistant pathogen as David Ricci found out. David’s case recently featured on the Four Corners Program “Rise of the Superbugs”.How many of you have treated a patient infected with a multi-resistant organism?How many of you know someone who has been infected with a multi-resistant pathogen?7. IDSA ‘Patient stories’ 201210
11 Antibiotic misuse drives antibiotic resistance Impact of resistanceIncreased morbidity/ mortalityEvidence across many pathogensUntreatable infectionsNow being encounteredIncreased costs$18-29,000 US/ patient8Antibiotic misuse drives antibiotic resistancePatients infected with resistant pathogens are more likely to have treatment failures, recurrent infections and delayed recovery. A two fold higher death rate has been reported amongst patients with antimicrobial- resistant infections.There is also a significant cost related to the treatment of resistant infections. And in Australia there are cases reported of infections with multi-resistant organisms that are untreatable with antibiotics.8. Roberts RR et al. Clinical Infectious Diseases 2009; 49:
12 High consumption is associated with increased resistance Countries with high penicillin consumption also have high rates of penicillin resistance in pneumococciOccurrence of penicillin-nonsusceptible Streptococcus pneumoniae (PNSP) versus outpatient use of penicillins in 17 European countries. Here we see the occurrence of penicillin-nonsusceptible Streptococcus pneumoniae (PNSP) plotted against outpatient use of penicillins in 17 European countries. DID = defined daily doses per 1,000 inhabitants. This clearly demonstrates the relationship of usage with development of penicillin resistance – as usage has increased so has resistance .9. van de Sande-Bruinsma N et al. Emerging Infectious Diseases 2008; 14(11):12
13 Consumption varies widely between countries Note: graph represents per capita consumptionThis graph show the difference in per capita consumption of antibiotics in outpatient/community setting in the US and 27 European countries. Australia is positioned in the middle with usage over twice that of the Netherlands.10. Goossens et al .Clin Infect Dis 2007; 44(8):13
14 Consumption varies between hospitals Even within a country – huge inter-hospital variation in antibiotic consumption e.g. meropenem use - 10-fold variation across 37 Australian hospitalsNational Antimicrobial Utilisation Surveillance Program (NAUSP) annual report11Even within a country there is huge inter-hospital variation in consumption of antibiotics (not easily accounted for by case-mix). There is a 10-fold variation in meropenum use across 37 Australian hospitals. Hospitals are mostly large tertiary institutions.Axis label: DDD per 1000 OBDs = Defined Daily Doses per 1000 Occupied Bed DaysNote – in addition to high consumption, there is evidence to suggest that up to 50% of antibiotic prescribing in Australian Hospitals is not in accord with guidelines (see Antimicrobial Stewardship in Australian Hospitals , 2011 )11.

15 Antibiotic usage in our hospital Insert local usage data if availableNote: This information should be available from the Pharmacy Department or local pharmacy contractor/supply service. If comprehensive data is not readily available, consider choosing one broad spectrum agent as an example.
16 Antibiotics are a limited resource Few new antibiotics being developedMost classes developed pre 1970Only 3 novel systemic classes in last 20 yearsGrowing recognition globally that:new antibiotics are urgently requiredwe need to conserve what we haveTo add to the problem of increased resistance and consumption, few new antibiotics are being developed.only three novel antibiotic classes have been developed in the last 20 years.although new antibiotics are urgently needed it is expected that few will be developed in the next 10 years.there is a need to conserve what we have.
17 In summary.... We have a problem ! Growing rates of resistance Inappropriate useDecreasing pipeline of new antibioticsIn summary we have a problem:There are growing rates of resistance to antibiotics in our hospitals and the communityThere are few new antibiotics being developedWhat antibiotics we do have we are not using appropriately12. Turnidge J et al. MJA 2009: 191(7):
18 Preserve the miracle of antibiotics by appropriate use. What can we do?Preserve the miracle of antibiotics by appropriate use.As antibiotic resistance increases and the development of new agents declines it is critical that we use antimicrobials wisely and judiciously. It is our responsibility to preserve the miracle of antibiotics.13. Carlet J et al. Lancet 2011: 378(9788):
19 What is inappropriate antibiotic use? Prescribing unnecessarilye.g. for viral infections, prolonged prophylaxisUsing broad spectrum agents when narrow spectrum agents are more appropriate.Dose too high or too lowDuration of treatment too longNot prescribing according to micro resultsTiming - omitting or delaying doseAntibiotics are used inappropriately when:They are prescribed unnecessarily such as for viral infections (colds), or for prolonged prophylaxisBroad spectrum antibiotics such as third generations cephalosposrins, carbapenems are used when a narrow spectrum antibiotic such as benzyl penicillin is effectiveWhen the dose given is too low (and there is treatment failure) or too highTreatment is continued for longer than necessary because courses are not time limited or no one remembers to cancel them.Antibiotics are not prescribed according to micro results.Doses are not given or administration is delayed.This effects ALL of us who prescribe, dispense or administer antibiotics – we ALL can play a part in making sure they are used appropriately and preserved for use in those infections where choice of therapy is limited.
20 “Appropriate use”?Prescribe according to current endorsed Therapeutic Guidelines: AntibioticCheck microbiology resultsReview empiric antibiotic therapy at hoursSeek infectious diseases/microbiology advice early for complex cases (insert process for ID consult here)Use pharmacy expertise for dosing advice (insert local processes here)Use the MINDME CreedHow can we use antibiotics appropriately?Prescribe in accordance with the latest edition of Therapeutic Guidelines:AntibioticUse microbiology results to improve antibiotic choice, streamline therapy to agent with a narrow spectrumReview empiric therapy at 48 – 72 hours . Convert to targeted therapy when the pathogen and its susceptibilities are known.Seek advice from clinical microbiology or infectious diseases physician early for complex cases.Consult a clinical pharmacist for advice on optimising the antibiotic doses.Follow the MINDME Antimicrobial Prescribing Creed14.

21 Antimicrobial stewardship (AMS) Part of broader system for infection prevention and control to minimise resistanceAim is to optimise use of antibiotics taking into account:Evidence of efficacyToxicityEcologic harm (effect on resistance)Requires team work at all levels:Executive and clinical leadershipPrescribers, clinicians, pharmacistsEssential elements: treatment guidelines, formulary with restrictions, selective susceptibility reporting of isolates, effective audit and feedback to prescribersAntimicrobial management or stewardship programs have been developed in response to the need to reduce unnecessary and inappropriate antibiotic use.They are part of a broader system for infection prevention and control to minimize resistanceAn AMS program alone is not sufficient to control resistance. To be effective a program needs to be established in conjunction with a comprehensive infection prevention and control program that includes hand hygiene, standard and transmission based precautions and cleaning and disinfection.Antimicrobial stewardship (AMS) is a systematic approach to optimising the use of antibiotics taking into account:Evidence of efficacyToxicity of the drugEcological harm – the effect on resistance or development of Clostridium difficile infection.Successful AMS requires executive support and clinical leadership as well as team work between prescribers, pharmacists and nurses.Essential elements of an AMS program include:Use of treatment guidelines that take into account local microbiological susceptibility patternsAn antibiotic formulary that includes restricting board spectrum and later generation antimicrobials to patients in whom use is clinically justified.Selective reporting of susceptibility testing consistent with hospital treatment guidelinesMonitoring and auditing antibiotic usage.Reviewing antibiotic prescribing with intervention and feedback to prescribers
22 National Safety & Quality Health Service Standards Standard 3: Antimicrobial Stewardship Criterion Actions required: An antimicrobial stewardship program is in place The clinical workforce prescribing antimicrobials have access to endorsed Therapeutic Guidelines on antibiotic usage Monitoring of antimicrobial usage and resistance is undertaken Action is taken to improve the effectiveness of antimicrobial stewardshipFrom January 2013 all hospitals and day procedure services undergoing accreditation will be assessed against the National Safety and Quality Health Service Standards.Standard 3 is the Standard for “Preventing and Controlling Healthcare Associated Infections” . There is an Antimicrobial Stewardship Criterion that forms part of the Standard.Hospitals are required to:Have an AMS program in placeProvide access to endorsed Therapeutic Guidelines on antibiotic usageMonitor their antimicrobial usage and resistance; andTake action to improve the effectiveness of their AMS program15.
