Theory-based interventions to reduce prescription of antibiotics-A randomized controlled trial in Sweden

• Background.: Upper respiratory tract infections (URTIs) are the most common reason for consulting a GP and for receiving an antibiotic prescription, although evidence shows poor benefit but rather increasing antibiotic resistance. Interventions addressing physicians have to take into consideration the complexity of prescribing behaviour. Objective.: To study whether interventions based on behavioural theories can reduce the prescribing of antibiotics against URTIs in primary care. Setting and subjects.: GPs at 19 public primary health care centres in southern Sweden. Methods.: We performed a randomized controlled study using two behavioural theory-based interventions, the persuasive communication intervention (PCI) and the graded task intervention (GTI), which emerged from social cognitive theory and operant learning theory. GPs were randomized to a control group or one of two intervention groups (PCI and GTI). Main outcome measures.: Changes in the rate of prescription of antibiotics against URTIs in primary care patients of all ages and in patients aged 0-6 years. Results.: No significant differences were seen in the prescription rates before and after the interventions when patients of all ages were analysed together. However, for patients aged 0-6 years, there was a significant lower prescription rate in the PCI group (P = 0.037), but not the GTI group, after intervention. Conclusion.: Theory-based interventions have limited impact on reducing the prescription of antibiotics against URTIs in primary care. Future studies are needed to draw firm conclusions about their effects. © The Author 2013. Published by Oxford University Press. All rights reserved.
