1. The interchangeable use of ‘awareness’ and ‘behaviour change’ is harming progress
Awareness of an issue is not enough to change people’s behaviour. Yet, when it comes to antibiotic stewardship interventions, the lines between the two are often blurred.
Campaigns that rely on awareness alone fail to support responsible drug-seeking and prescribing practices in a sustainable way. This undermines the potential of behavioural science.
The partnership between the Behavioural Insights Team and Public Health England is a great example of truly looking at antibiotic stewardship through a behavioural lens. Their 2015 review of resistance-driving behaviours led to the trial of social norm feedback to improve antibiotic prescription practices by GPs in the UK – this showed potential for sustained impact.
2. Human-focused research is vital to create effective and accepted tools
Behavioural research should not only be tested with people but co-created with them. By embracing a human-focused perspective from development to implementation, we can more accurately identify key behaviours and levers for change, all while gaining validation and support from target communities.
Our human-centred design project showed first-hand how understanding prescribers and patients – the decision-makers and end-users – can pinpoint opportunities for change in antibiotic use. For example, by mapping patient care journeys we noticed key moments at which a behavioural intervention could improve prescribing practices while also supporting good care.
But we didn’t spend enough time understanding the context. The project focused on digital interventions that, while helpful, were not scalable in those countries. Aligning with new technology is a good tactic, but only by understanding people in their communities can we develop appropriate, accepted and effective behavioural approaches.
3. Start with ‘gatekeepers’ to understand the big picture
Antimicrobial ‘gatekeepers’ include all those who provide antibiotics: doctors, pharmacists, community healthcare workers and alternative caregivers. Their names and responsibilities vary across countries and health systems.
Starting with everyone in this group provides a holistic understanding of how antibiotics are prescribed and sold in the community. These big picture insights help to hone in on the most suitable targets and approaches for intervention.
Heading into our project we hoped to develop interventions focused on retail pharmacists. We scoped some interesting concepts that tried to sidestep financial drivers to provide antibiotics through encouraging customer loyalty based on good care, not prescriptions.
But we struggled to tap into this sector successfully. Looking at the wider ‘gatekeeper’ base we saw that GPs were most ready and willing to change, given the right tools – so this group became our target.
4. Generalising can help us create rapid, widespread change
As behaviours are context-specific, the most effective behaviour change approaches are tailored to audiences and their setting. But we must be prepared to generalise to some extent, given the infinite number of contexts globally where antibiotic stewardship initiatives would be useful.
Identifying similarities and differences between settings allows us to share and repurpose existing evidence, rather than starting from scratch.
For example, by talking to ‘gatekeepers’ in India and Kenya (pictured below) we found common characteristics that drove prescription practices: level of training and whether they perceived antibiotic consumers as patients or customers.
Recognising common characteristics across different contexts helps scale ideas. This is vital to create change more widely. Critical to this is deciding what is ‘good enough’ and appreciating that waiting for a perfect or permanent solution will not help us advance antibiotic stewardship quickly.
