Tackling the global spread of antibiotic resistance is a high priority for the World Health Organization (WHO).
Evaluation of the impact of antibiotic awareness campaigns is still suboptimal, with 36 of 60 campaigns (60%) reporting no formal evaluation. The most effective messages and interventions remain unclear. The lack of thorough evaluation, the absence of prospectively determined control groups and the multifaceted nature of most campaigns makes any formal conclusions difficult. It seems, however, that some campaigns were associated with a reduction in overall antibiotic use.
