Antibiotic resistance – A patient safety issue for all hospitals

• The emergence, selection and spread of resistant bacteria in hospitals is a major patient safety issue. – Infections with antibiotic-resistant bacteria can result in

increased patient morbidity and mortality, as well as increased hospital length of stay.1-2

– Antibiotic resistance frequently leads to a delay in appropriate antibiotic therapy.3

– Inappropriate or delayed antibiotic therapy in patients with severe infections is associated with worse patient outcomes and sometimes death.4-6

• These infections have resulted in [insert data on additional days of hospitalisation, morbidity, mortality, and costs where available].

Why inappropriate use of antibiotics contributes to antibiotic resistance

– the “why”

11

In-patients are at high risk of antibiotic-resistant infections

• Misuse of antibiotics in hospitals is one of the main factors that drive development of antibiotic resistance.7-9

• Patients in hospitals have a high probability of receiving an antibiotic10 and 50% [adapt to national figure where available] of all antibiotic use in hospitals can be inappropriate.11-12

Misuse of antibiotics drives antibiotic resistance

• Studies prove that misuse of antibiotics may cause patients to become colonised or infected with antibiotic-resistant bacteria, such as meticillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE) and highly-resistant Gram-negative bacilli.13-14

• Misuse of antibiotics is also associated with an increased incidence of Clostridium difficile infections.15-17

What is misuse of antibiotics?

14

Misuse of antibiotics can include any of the following18:

• When antibiotics are prescribed unnecessarily; • When antibiotic administration is delayed in critically ill

patients; • When broad-spectrum antibiotics are used too

generously, or when narrow-spectrum antibiotics are used incorrectly;

• When the dose of antibiotics is lower or higher than appropriate for the specific patient;

• When the duration of antibiotic treatment is too short or too long;

• When antibiotic treatment is not streamlined according to microbiological culture data results.

Benefits of prudent use of antibiotics

• Prudent use of antibiotics can prevent the emergence and selection of antibiotic-resistant bacteria.19-23

• Decreasing antibiotic use have also been shown to result in lower incidence of Clostridium difficile infections.24-26

How prudent use of antibiotics can be promoted in hospitals

– the “how”

16

Multifaceted strategies can address and decrease antibiotic resistance in hospitals

• Antibiotic prescribing practices and decreasing antibiotic resistance can be addressed through multifaceted strategies including:29-31

Use of ongoing education Use of evidence-based hospital antibiotic

guidelines and policies Restrictive measures and consultations from

infectious disease physicians, microbiologists and pharmacists

Measures that can decrease antibiotic resistance

18

Measures that guide antibiotic prescribing are likely to decrease antibiotic resistance in hospitals.32-34 Such measures include:

Obtaining culturesTake appropriate and early cultures before initiating empiric antibiotic therapy, and streamline antibiotic treatment based on the culture results35

Monitoring local antibiotic resistance patternsBeing aware of local antibiotic resistance patterns (antibiograms) enables appropriate selection of initial empiric antibiotic therapy36

Consulting specialistsInvolve infectious disease physicians, microbiologists and pharmacists in your decisions about antibiotic therapy during your patient’s stay37-39

Antibiotics – handle with care

• Misuse of antibiotics leads to resistance40-42

• All hospital practitioners can play an active role in reversing the trend of antibiotic-resistant bacteria:– Take cultures before starting antibiotic therapy43

– Consult the hospital antibiotic expert44-46, [local antibiogram, and hospital antibiotic guidelines]

– Streamline antibiotic therapy based on culture results47
