Cross-national comparison of paediatric antibiotic use in Norway, Portugal and Hungary

Outcomes of antibiotic treatment for respiratory infections in children an observational study in primary care

BACKGROUND

Antibiotic resistance is an increasing global threat, accelerated by both misuse and overuse of antibiotics. Most antibiotics to humans are prescribed in primary care, commonly for respiratory symptoms, and there is a need for research on the usage of and outcomes after antibiotic treatment to counteract antibiotic resistance.

OBJECTIVE

To evaluate symptom duration, treatment length, and adverse events of antibiotic treatment in children.

DESIGN AND SETTING

Observational study at four out-of-hours services and one paediatric emergency clinic in Norwegian emergency primary care.

SUBJECTS

266 children aged 0 to 6 years with fever or respiratory symptoms.

MAIN OUTCOME MEASURES

Duration of symptoms and absenteeism from kindergarten/school, treatment length, and reported adverse events.

RESULTS

There were no differences in duration of symptoms, fever or absenteeism when comparing the groups prescribed (30.8%) and not prescribed (69.2%) antibiotics. This lack of difference remained when analysing the subgroup with otitis media.In the group prescribed antibiotics, 84.5% of parents reported giving antibiotics for 5-7 days, and 50.7% reported no difficulties. Adverse events of antibiotics were reported in 42.3% of the cases, the vast majority being gastrointestinal disturbances.

CONCLUSION

Children with fever or respiratory symptoms experience similar duration of symptoms and absenteeism regardless of antibiotic treatment. A substantial number of parents reported adverse events when the child received antibiotics. Several parents experienced additional difficulties with the treatment, some ending treatment within day 4.

Antibiotic Use in Children Before, During and After Hospitalization

Purpose

To investigate ambulatory antibiotic use in children during 1 year before and 1 year after in‐hospital antibiotic exposure compared to children from the general population that had not received antibiotics in‐hospital.

Methods

Explorative data‐linkage cohort study from Norway of children aged 3 months to 17 years. One group had received antibiotics in‐Hospital (H+), and one group had not received antibiotics in‐hospital (H‐). The H+ group was recruited during admission in 2017. Using the Norwegian Population Registry, 10 children from the H‐ group were matched with one child from the H+ group according to county of residence, age and sex. We used the Norwegian Prescription Database to register antibiotic use 1 year before and 1 year after the month of hospitalisation.

Results

Of 187 children in the H+ group, 83 (44%) received antibiotics before hospitalisation compared to 288/1870 (15%) in the H‐ group, relative risk (RR) 2.88 (95% confidence interval 2.38–3.49). After hospitalisation, 86 (46%) received antibiotics in the H+ group compared to 311 (17%) in the H‐ group, RR 2.77 (2.30–3.33). Comorbidity‐adjusted RR was 2.30 (1.84–2.86) before and 2.25 (1.81–2.79) after hospitalisation. RR after hospitalisation was 2.55 (1.99–3.26) in children 3 months‐2 years, 4.03 (2.84–5.71) in children 3–12 years and 2.07 (1.33–3.20) in children 13–17 years.

Conclusions

Children exposed to antibiotics in‐hospital had two to three times higher risk of receiving antibiotics in ambulatory care both before and after hospitalisation. The link between in‐hospital and ambulatory antibiotic exposure should be emphasised in future antibiotic stewardship programs.

Prescribing Patterns and Variations of Antibiotic Use for Children in Ambulatory Care: A Nationwide Study

The aim of this study was to analyse characteristics of paediatric antibiotic use in ambulatory care in Hungary. Data on antibiotics for systemic use dispensed to children (0–19 years) were retrieved from the National Health Insurance Fund. Prescribers were categorised by age and specialty. Antibiotic use was expressed as the number of prescriptions/100 children/year or month. For quality assessment, the broad per narrow (B/N) ratio was calculated as defined by the European Surveillance of Antimicrobial Consumption (ESAC) network. Paediatric antibiotic exposure was 108.28 antibiotic prescriptions/100 children/year and was the highest in the age group 0–4 years. Sex differences had heterogenous patterns across age groups. The majority of prescriptions were issued by primary care paediatricians (PCP). The use of broad-spectrum agents dominated, co-amoxiclav alone being responsible for almost one-third of paediatric antibiotic use. Elderly physicians tended to prescribe less broad-spectrum agents. Seasonal variation was found to be substantial: antibiotic prescribing peaked in January with 16.6 prescriptions/100 children/month, while it was the lowest in July with 4 prescriptions/100 children/month. Regional variation was prominent with an increasing west to east gradient (max: 175.6, min: 63.8 prescriptions/100 children/year). The identified characteristics of paediatric antibiotic use suggest that prescribing practice should be improved.

Antibiotic prescriptions for children younger than 5 years with acute upper respiratory infections in China: a retrospective nationwide claims database study

Background

In China, there were few studies to estimate antibiotic use for children with upper respiratory infections at the national level. The aim of this study was to describe the antibiotic prescribing practice for children aged < 5 years old with upper respiratory infections (URIs) using a nationwide claims database.

Methods

This was a retrospective cross-sectional study using a sampled database from the China Health Insurance Research Association (CHIRA). Study subjects included children younger than 5 years with outpatient visits in 2015 that resulted in a diagnosis of a upper respiratory infection. We calculated the percentage of visits who received antibiotics, the proportion of injection formulations, the percentage of combined antibiotics and the proportion of each antibiotic class. The patterns of antibiotic prescription were also described by medical institution type, city level and geographical region.

Results

Among the 92,821 visits, 27.1% were prescribed antibiotics, of which 27.0% received injection formulations. The rate of antibiotic prescribing varied by age group (P < 0.001), with the lowest (16.0%) in infants and the highest in patients at age 3 to < 4 years (29.9%) and age 4 to < 5 years (32.5%). The Midwestern region, underdeveloped cities and low-level hospitals represented relatively higher rates of prescribing antibiotics (P < 0.001) and higher proportions of injection dosage forms (P < 0.001). The most 3 common antibiotic classes prescribed of all visits with antibiotic prescriptions were the third-generation cephalosporins (34.9%), macrolides (24.3%), and the second-generation cephalosporins (23.3%).

Conclusions

In mainland China, the overall rate of antibacterial prescribing and the proportion of injection formulations prescribed in children under 5 years with URIs were at a low level, but still higher in underdeveloped regions and cities. Moreover, the overuse of the second and third generation cephalosporins, macrolides, remains a serious issue. Further efforts should be focused on reducing those non-first-line antibiotic prescribing and narrowing the gaps among regions and cities.

Marked reductions in outpatient antibiotic prescriptions for children and adolescents - a population-based study covering 83% of the paediatric population, Germany, 2010 to 2018

BackgroundPrescribing of systemic antibiotics in general and of cephalosporins in particular in German paediatric outpatients has previously been reported to be higher than in other European countries.AimOur objective was to assess recent trends in antibiotic prescribing in German children.MethodsThis study was conducted as consecutive annual cross-sectional analyses and included all children aged 0-14 years (n = 9,389,183 in 2018) covered by statutory health insurance in Germany. Annual antibiotic prescription rates from 2010 to 2018 were calculated for the age groups 0-1, 2-5, 6-9 and 10-14 years. Poisson regression was used to estimate trends of prescription rates by age group and antibiotic subgroup.ResultsOverall, the age-standardised antibiotic prescription rate decreased significantly by 43% from 746 prescriptions per 1,000 persons in 2010 to 428 per 1,000 in 2018 (p < 0.001). Reductions were most pronounced in the age groups 0-1 year (-50%) and 2-5 years (-44%). The age group 2-5 years exhibited the highest prescription rate with 683 per 1,000 in 2018 (0-1 year: 320/1,000; 6-9 years: 417/1,000; 10-14 years: 273/1,000). Cephalosporins (second and third generation) accounted for 32% of prescribed antibiotics.ConclusionsMarked reductions in antibiotic prescribing during the last decade indicate a change towards more judicious paediatric prescribing habits. Compared with other European countries, however, prescribing of second- and third-generation cephalosporins remains high in Germany, suggesting frequent first-line use of these substances for common respiratory infections. Considerable regional variations underline the need for regionally targeted interventions.
