Background: To describe the utilisation of antibiotics in children and adolescents across 5 European countries based on the same drug utilisation measures and age groups. Special attention was given to age-group-specific distributions of antibiotic subgroups, since comparison in this regard between countries is lacking so far.Methods: Outpatient paediatric prescriptions of systemic antibiotics during the years 2005-2008 were analysed using health care databases from the UK, the Netherlands, Denmark, Italy and Germany. Annual antibiotic prescription rates per 1,000 person years were estimated for each database and stratified by age (≤4, 5-9, 10-14, 15-18 years). Age-group-specific distributions of antibiotic subgroups were calculated for 2008.Results: With 957 prescriptions per 1000 person years, the highest annual prescription rate in the year 2008 was found in the Italian region Emilia Romagna followed by Germany (561), the UK (555), Denmark (481) and the Netherlands (294). Seasonal peaks during winter months were most pronounced in countries with high utilisation. Age-group-specific use varied substantially between countries with regard to total prescribing and distributions of antibiotic subgroups. However, prescription rates were highest among children in the age group ≤4 years in all countries, predominantly due to high use of broad spectrum penicillins.Conclusions: Strong increases of antibiotic prescriptions in winter months in high utilising countries most likely result from frequent antibiotic treatment of mostly viral infections. This and strong variations of overall and age-group-specific distributions of antibiotic subgroups across countries, suggests that antibiotics are inappropriately used to a large extent.

PURPOSE: To examine patterns of outpatient and community antibiotic use among adults in five European countries.METHODS: We used healthcare data of 28.8 million adults from six population-based ARITMO project databases to ascertain information on systemic antibiotic use in Denmark (2000-2008), the Netherlands (1999-2010), Italy (2000-2010), the UK (1996-2009), and Germany (2004-2008). We estimated overall, and age-group and sex specific antibiotic use as defined daily doses (DDD) per 1000 inhabitants per day. We computed annual age- and sex-standardized population prevalence of antibiotic use per 1000 persons-years (p-y) and the mean duration (in days) of antibiotic use.RESULTS: The overall antibiotic use varied from 8.7 DDD per 1000 inhabitants per day in the UK to 18.1 DDD in Denmark, representing a 2.1-fold geographical variation. In all countries, prescribing was relatively high among individuals aged 15-19 years; lower in those aged 20-50 years; and then increased steadily reaching 41.8 DDD per 1000 inhabitants per day in individuals ≥85 years in Denmark. After age- and sex-standardization, prevalence of antibiotic use varied threefold from 160.2/1000 p-y in the UK to 421.1/1000 p-y in Italy. The ratio of broad- to narrow-spectrum penicillin, cephalosporin, and macrolide use varied from 0.6 in Denmark to 120.2 in Italy. Women used more antibiotics than men did in all countries. Across countries, the mean duration of antibiotic use varied 1.3 to 21.1-fold for different antibiotics.CONCLUSIONS: Antibiotic use is high in women and the elderly. Prescribing patterns vary substantially across European countries, both according to overall consumption, user prevalence, duration, and narrow- versus broad-spectrum antibiotics.

Purpose The study aims to analyse overall as well as subgroup-specific outpatient paediatric macrolide use in five European countries, including time trends of macrolide prescription rates, and to provide potential targets for future interventions aiming to promote judicious macrolide use. Methods Macrolide prescription rates per 1000 person years to paediatric outpatients (a parts per thousand currency sign18 years) were calculated using healthcare databases from Denmark, Germany, Italy, The Netherlands and the UK. Poisson regression analysis was used to estimate the influence of increasing calendar year on total macrolide and subgroup-specific prescription rates based on monthly data, adjusted for seasonal variations. Time periods for which data were available varied between 4 (Italy 2007-10, Germany 2005-8) and 10 years (UK 2000-9). Results Paediatric macrolide use in 2008 varied between 199 (Italy) and 47 (Netherlands) prescriptions per 1000 person years. Prescription rates of short-acting macrolides declined significantly in all countries but the UK. The use of intermediate-acting macrolides significantly rose with increasing calendar year in Denmark (rate ratio (RR) = 1.12) and the UK (RR = 1.06), but decreased in Germany (RR = 0.84) and The Netherlands (RR = 0.97). Prescription rates of long-acting agents increased in Denmark (RR = 1.05), The Netherlands (RR = 1.05) and the UK (RR = 1.11) (all trends p < 0.05). The greatest seasonal variations of macrolide use between summer and winter months were observed in Italy and Germany. Conclusions The observed trend toward increased prescribing of intermediate- and/or long-acting agents might further increase resistance pressure on bacterial pathogens due to their prolonged plasma half-life and broader antibacterial activity. Marked seasonality of prescription rates in the high-utilising countries, Italy and Germany, suggests frequent prescription of macrolides to treat respiratory infections which may be of viral origin.
