6. Background-Aims
• Purpose of Antibiotic Guardian (AG) campaign:
• Increase engagement with the rising threat of Antimicrobial Resistance (AMR)
• Concrete personal and collective action to help keep antibiotics active
• Provide a system to measure behaviour change
• First example of online pledge system to improve AMR related knowledge
and behaviour amongst healthcare professionals and the general public
• Aim of current evaluation: assess whether the AG achieved its goals

7. Methods - Questionnaire
• Online questionnaire: Evaluation of the Antibiotic Guardian campaign
2014
• Sent via e-mail to 9016 out of all 11833 Antibiotic Guardians who consented
for follow up (3rd of February 2015)
• Survey included questions on:
• Type of pledge & Motivation
• Change in behaviour (acting according to pledge)
• Knowledge acquired
• Clarity of promotion materials
• Demographics (age, sex, health-related profession, use of social media)

8. Methods – Statistical Analysis
• Distribution of demographic variables
• Questions analysed as the outcomes of interest:
• Change in behaviour: “Since you became an Antibiotic Guardian, have you acted
in line with your pledge?” (categorical)
• Change in knowledge: “After becoming an Antibiotic Guardian, do you feel that
you have acquired more knowledge on what antibiotic resistance is?” (binary)
• Promotion of the AG campaign: “Indicate your agreement with the statement: “I
think the AG campaign is well promoted” (categorical)
• Logistic and Ordinal Logistic regression models, adjusted for age, sex
and pledge group used to estimate associations

9. Results - Respondents
• 2478 AGs responded: 27.5% response rate
• 1696 pledged as healthcare professionals (68%)
• 782 pledged as members of public (32%)
↓
similar to proportions at total population of 11,833 AGs
• 76.9% were connected to the healthcare system
• 96.3% had prior knowledge of AMR

11. Results - Behaviour
• 43.9% remembered completely the meaning of their pledge
• 63.4% reported always acting according to their pledge
• Members of public more likely to act according to their pledge than
healthcare professionals (OR=3.60, CI: 2.88-4.51)
• Respondents without positive pre-campaign pledge behaviour less likely to
have positive post campaign pledge behaviour (OR=0.23, CI: 0.16-0.34)
• AGs that remembered the pledge more likely to have positive post
campaign behaviour (OR=1.96, CI: 1.63-2.36)

12. Results - Knowledge
• 44.5% acquired more knowledge about AMR post campaign
• Sense of personal responsibility towards tackling AMR increased by
12.2% post campaign
• People confused about AMR prior to the AG campaign acquired more
knowledge after the campaign (OR =3.10, CI: 1.36 – 7.09)
• Respondents without pre-campaign knowledge more likely to acquire
knowledge on AMR post campaign (OR=4.21, CI: 2.04 – 8.67)
• Members of the public less likely to have acquired more knowledge post
campaign than healthcare professionals (OR= 0.79, CI: 0.66 – 0.96)

13. Results - Promotion
• 61.7% agreed to different extents that the AG campaign was well
promoted
• 56.7% seemed to think that the website itself was the best source of
information
but
more than half of AGs have not seen most promotion materials
Combating AMR (CPC Conference) Dr Diane Ashiru-Oredope
14. Conclusion
• Good response of an overall representative sample in terms of proportions
of different pledge groups
• Effective in achieving positive changes in behaviour and an increase in
knowledge amongst people with prior awareness of the topic
• Less successful in engaging people without previous professional or
personal experience of AMR
• Majority thought the campaign was well promoted but most materials were
not seen

15. Recommendations
• Regular communication with pledgees via e-mails or newsletters to
remind their pledge and provide information
• Engage wider members of public → initiatives for alternative promotion
methods to get the public aware and engaged with the campaign
• Evaluations should be built into the design of future campaigns → capture
pre and post campaign effects

16. Next steps
• Qualitative methods applied to explore the results from the quantitative
analysis
Qualitative interview study will seek to identify how the AG campaign was engaged
with and the mechanisms of impact from the perspective of those who became AG
