Doctors and local media: a synergy for public health information?: a controlled trial to evaluate the effects of a multifaceted campaign on antibiotic prescribing (protocol).
BACKGROUND
Use of information campaigns and educational interventions directed to citizens and supported by physicians, aimed at promoting the appropriate use of medicines, have been evaluated by several studies with conflicting results. These interventions are potentially relevant, favouring the reduction of unnecessary use of medicines and related risks. Several studies have specifically evaluated the promotion of the appropriate use of antibiotics in adults and children, with variable results. A controlled study is proposed to evaluate the feasibility and effectiveness of a multifaceted intervention aimed at reducing antibiotic prescription by increasing awareness on risks of their unnecessary use.


METHODS
Information will be provided to citizens through several media (posters, local TV, radio and newspapers, video terminals, websites of Local Health Authorities). Brochures with information on expected benefits and risks of antibiotics will be also available, either with direct access in waiting rooms and pharmacies or handed out and mediated by doctors. Physicians and pharmacists will get specific data on local antibiotic resistance. A small group of representative doctors have also actively participated in defining the campaign key messages. A sample of general practitioners and paediatricians will be trained in patient counselling strategies.The information campaign will be implemented in two Provinces of Emilia-Romagna during the fall-winter season (November 2011-February 2012). Change in the overall prescribing rate of antibiotics (expressed as DDD per 1000 inhabitants/day) in the intervention area will be compared versus other areas in the same Region. Knowledge and attitudes of the general population will be evaluated through a phone and internet survey on a representative sample.


CONCLUSIONS
While the campaign messages will be mainly directed to the general population, doctors' prescribing will be assessed. The main rationale for this apparent discrepancy lies in the influence patients may have on physicians' prescribing behaviour (directly or indirectly) and in physicians' endorsement of the campaign goals, considering their participation in its design.This study could observe a reduction lower than 5% in the prescribing rate of antibiotics. Such a reduction would be of public health relevance and would determine average savings of almost twice as much as the campaign costs.
