[Outpatient Antibiotic Prescription Rates and Mastoiditis in Children and Adolescents, Saarland, 2014-2019].

Background: Infections of the respiratory tract are the main indication for outpatient antibiotic therapy in children and adolescents. In recent years the antibiotic prescription rate (APR) in the pediatric population has decreased significantly.
Objectives: The aim of the retrospective mastoiditis audit in the PaedineSaar network is to investigate the incidence of inpatient acute mastoiditis (AM) in Saarland (2014-2019) regarding to the decreasing APRs in children, as well as to gather data of the clinical course of AM.
Methods: All inpatient AM cases 2014-2019 were analyzed retrospectively from 6 hospitals for pediatrics and/or otorhinolaryngology in Saarland and Trier. Children and adolescents aged 0-17 years and residing in Saarland were included in the study.
Results: 2014-2019 53 inpatient treated AM cases have been recorded. During the study period there was no significant increase of AM incidence (mean incidence 2014-2019: 6.1/100,000). 34% (18/53) of the patients received prehospital antibiotic treatment (main indication: acute otitis media (AOM) 15/18, 83%). At least one complication occurred in 30% of the patients (16/53). There was a slight trend to more complications in children without oral antibiotic treatment before admission (14/35 (40%) vs. 2/18 (11%) p=0.056).
Conclusions: The incidence of AM leading to inpatient treatment in children in Saarland did not increase 2014-2019 despite a significant and sustained decline in the outpatient APRs. The results of this audit should be used for the development of a more standardized approach concerning the diagnostics and treatment of children with AM.
