Presentation Transcript

  1. Overview • Antibiotics – miracle medicines • Antibiotic resistance – a critical global problem • The link between antibiotic use and resistance • Addressing antibiotic resistance • The role of antimicrobial stewardship • Prescribing and using antibiotics with care Whenever they are used, antibiotics must be used with care.

  2. The “miracle” of antibiotics • Discovery of penicillin revolutionised treatment of infectious disease • Increased life expectancy due to ability to prevent and treat infection Crude mortality rates for all causes, non infectious causes and infectious diseases over the period 1900-1996. 1. Armstrong GL et al, JAMA 1999;281(1):61-66

  3. Antibiotics continue to save lives,every day… • Ability to control infection is critical to other advances in medicine • Neonatal care • Transplantation • Chemotherapy • Immunosuppression • Complex and routine surgery • Obstetric care • Intensive care interventions

  4. But…antibiotics are a limited resource 2. Spellberg, B. et al. Clinical Infectious Diseases 2008; 46 (2):155-64 3. Gottlieb, T and Nimmo, G. Medical Journal of Australia 2011; 194 (6): 281-3 • Increasing antibiotic resistance • Increased use of antibiotics • Decreasing pipeline of new antibiotics Urgent call to action

  5. Emergence of antibiotic resistance “It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them, and the same thing has occasionally happened in the body.” Sir Alexander Fleming, 1945 The issue of antibiotic resistance was recognised early in the ‘antibiotic era’. It threatens our ability to control infection. 4. Sir Alexander Fleming, Nobel Lecture, December 1945

  6. Emergence of antibiotic resistance Antibiotic resistance threatens ability to control infection 5. Pray LA Insight Pharma Reports 2008, in Looke D ‘The Real Threat of Antibiotic Resistance’ 2012

  7. Resistance spreads rapidly 6. Centers for Disease Control and Prevention http://www.cdc.gov/hai/

  8. Impact of resistance: real people are affected • Increased morbidity/mortality • Evidence across many pathogens • Pan drug resistant infections • Now being encountered • Increased costs • $18-29,000 US/patient • Excess length of stay 6.4 – 12.7 days/patient Glen’s story 7.

  9. Antibiotic resistance: a global problem… Key findings: • Very high rates of resistance observed for common bacteria that cause health care associated and community acquired infections (for example urinary tract, pneumonia) in all WHO regions. • Significant gaps in surveillance. • Urgent need to strengthen collaboration on global surveillance as the foundation of global strategies to address antimicrobial resistance (AMR). 10.

  10. ...a problem in our region High prevalence of drug resistance reported in clinically important pathogens including serious hospital acquired skin infections. For example • prevalence rates of 77.6% and 74.1% of methicillin-resistant S. aureus reported in Republic of Korea and Vietnam respectively. • prevalence rates of 68–90% of gonorrhoea infections with reduced susceptibility and resistance to quinolones reported in Japan, Malaysia and Singapore. 11.

  13. Antibiotic resistance locallyWhat is happening in our health service • Which infections are we seeing? • What are our susceptibility and resistance patterns ? • [Insert hospital data] • [Numbers of cases] • [Examples of cases]

  14. The link between use and resistance Countries with high penicillin consumption also have high rates of penicillin resistance in pneumococci Occurrence of penicillin-nonsusceptible Streptococcus pneumoniae (PNSP) versus outpatient use of penicillins in 17 European countries. 17. van de Sande-Bruinsma N et al. Emerging Infectious Diseases 2008; 14(11):1722-1730

  15. Antibiotic usage varies Overall antimicrobial usage rates (N=129) NAUSP 2014 * Antimicrobial use in Australian hospitals: 2014 annual report of the National Antimicrobial Utilisation Surveillance Program http://www.safetyandquality.gov.au/publications/antimicrobial-use-in-australian-hospitals-2014-report-of-the-national-antimicrobial-utilisation-surveillance-program/ Within the country there is variation in consumption of antibiotics, not easily accounted for by case-mix. .

  16. Antibiotic usage varies Between hospitals consumption also varies. Annual carbapenem usage by AIHW* peer group (FY2014-15) *Australian Institute of Health and Welfare 19. Data source: National Antimicrobial Utilisation Surveillance Program (NAUSP) – unpublished data

  17. Antibiotic use in Australian Hospitals 30-40% of hospitalised patients are prescribed antibiotics20,21 The 2014 NAPS* Report indicates that around one quarter of antibiotics prescribed in Australian hospitals are prescribed inappropriately21 Australian hospitals dispense higher volumes of antibiotics than some other countries22 *Hospitals that participate in NAPS are provided with data on the appropriateness of their own prescribing patterns for local quality improvement. 20.

  18. What is inappropriate use ? Inappropriate use includes: • Using broad-spectrum antibiotics (such as third generation cephalosporins, carbapenems) when narrow-spectrum antibiotics are effective • Prescribing too low or too high a dose of antibiotic • Not prescribing according to microbiology results • Continuing treatment for longer than necessary • Omitting doses or delayed administration. Top reasons for inappropriate use – NAPS 2014

  19. Adding to the problem …Antibiotics are a limited resource The dwindling development of antibiotics… number of US FDA Antibiotic approvals23 Few new antibiotics • majority developed pre 1970 • 3 new classes in 20 years Global recognition that: • new antibiotics are urgently required • need to conserve what we have now 24 23: Adapted from Spellberg B et al.

  20. Antibiotic usage in our health service • Insert local usage data if available • Include information about • Contributions to National Antimicrobial Usage Surveillance Program (NAUSP)

  21. What about antibiotic appropriateness in ourhealth service? • Insert local prescribing data including • Participation in the National Antimicrobial Prescribing Survey, results and trends over time if relevant.

  22. The National Antimicrobial Resistance (AMR) Strategy25Responding to the threat of AMR Seven objectives focused on • Awareness, education • Antimicrobial stewardship • Surveillance • Infection prevention and control • International management • Research and development • Governance 25. Commonwealth of Australia. National Antimicrobial Resistance Strategy. 2015. Access at: www.health.gov.au/amr

  23. Addressing antibiotic resistance: a multidisciplinary, comprehensive approach Prevent and manage infections Infection prevention and control Includes hand hygiene, standard and transmission-based precautions, environmental cleaning. Prolong effectiveness of existing antibiotics Antimicrobial stewardship Addressing antibiotic resistance is everybody’s business.

  24. Antimicrobial stewardship (AMS) Principles: promote best clinical outcome for the treatment or prevention of infection minimal toxicity to the patient minimal impact on resistance and other adverse events timely and optimal selection, dose and duration of an antimicrobial. Requires team work at all levels: “everybody's business" executive and clinical leadership clinical team (doctors, nurses, pharmacists, allied health) consumers.

  28. Antimicrobial Use and Resistance in Australia • The AURA Project will establish a national antimicrobial usage and resistance surveillance system by June 2016. • Working with existing programs, such as NAPS and NAUSP, will enhance capacity for surveillance and build new systems such as the National Alert System for Critical Antimicrobial Resistances (NASCAR). • The key objective is to increase access to data for action against AMR. • Funded by the Australian Government Department of Health. • http://www.safetyandquality.gov.au/national-priorities/amr-and-au-surveillance-project/

  29. Antimicrobial stewardship in our hospital • Multidisciplinary, team approach • Local roles and responsibilities • Medicine, nursing, pharmacy • Consumer participation • Executive and clinical leaders • Local processes for stewardship • Include local processes for • seeking ID/micro consults • guideline and formulary information • pharmacy advice • contacts • other relevant information.

They are important movers, shakers, and front-line players, especially in this age of social media.” Dr Margaret Chan30 30. Dr Margaret Chan, Keynote address at the conference on Combating antimicrobial resistance: time for action Copenhagen, Denmark 14 March 2012 . http://www.who.int/dg/speeches/2012/amr_20120314/en/ last accessed 22/9/14

  39. Remember… Antibiotics are a limited, precious resource Antibiotics are a precious resource that could be lost. Antibiotic resistance is happening now – it is a worldwide problem that affects human and animal health. Antibiotic resistance happens when bacteria stops an antibiotic from working effectively – meaning some infections may be impossible to treat. Misuse of antibiotics contributes to antibiotic resistance. Few new antibiotics are being developed to help solve this problem. To preserve the miracle of antibiotics, whenever they are used, antibiotics must be used with care.
