Appropriateness of antibiotic prescribing in paediatrics: retrospective controlled study assessing a multifaceted intervention in Northern Italy in a 7-year period

Abstract

BackgroundAcademic detailing, audit and feedback, and peer comparison have been advocated as effective ways to promote appropriateness of prescribing and antimicrobial stewardship (AMS). This study explored the effectiveness of a multifaceted intervention aimed at supporting the appropriateness of antibiotic prescribing in paediatrics.MethodsOver the course of 7 years, all 89 paediatricians of the Local Health Authority (LHA) of Reggio Emilia (530 000 residents) were provided with scientific literature focused on antimicrobial resistance and the appropriateness of use of specific antibiotics, together with local data on antimicrobial resistance and prescribing reports comparing each paediatrician with colleagues in the same district and with local averages. Prescribing rates of specific target antibiotics/classes of antibiotics were evaluated by comparing Reggio-Emilia with the other seven LHAs of the Emilia-Romagna Region (control area), adjusting for prescriptions during a 2-year baseline period.ResultsA significant increase in the rate of amoxicillin prescriptions (91 more per 1000 children/year) was observed in the intervention area compared with the control area along with a significant reduction in the rate of amoxicillin+clavulanate prescriptions (70 fewer per 1000 children/year) and a significant increase in the ratio of their prescription rates. No differences were observed in cephalosporin and macrolide prescription rates and overall antibiotic prescriptions.ConclusionsImprovements in prescribing appropriateness were observed. This study confirms the importance of an audit and feedback approach through small group meetings supported by scientific literature, local resistance data and prescribing reports. Such approach should always be considered as part of multifaceted interventions to promote AMS.
