The session will provide an overview for a research project which used behavioural science to develop an intervention to reduce prescribing of liquid Amoxicillin. This is important and liquid Amoxicillin releases approximatley three times the amount of carbon as capsules, is much more expensive and has worse treatment adherence compared to Amoxicillin capsules. Attendees will gain an understanding of simple and effective techniques to change prescribing behaviours.
