Insights
Drug use in European children varies by class, with anti-infectives and respiratory medications frequently prescribed. This study highlights patterns in paediatric drug use to guide future research.
Area of Science:
- Paediatric Pharmacology
- Drug Utilization Research
- European Public Health
Background:
- Understanding paediatric drug prescription patterns is crucial for optimizing child health outcomes.
- Previous research has not comprehensively analyzed drug use across diverse European paediatric populations.
- Identifying trends in paediatric medication use can inform therapeutic research and clinical guidelines.
Purpose of the Study:
- To present a comprehensive overview of outpatient paediatric drug utilization in the Netherlands, United Kingdom, and Italy.
- To analyze the prevalence of drug use by therapeutic class and identify patterns of recurrent versus acute prescribing.
- To evaluate the off-label use of commonly prescribed medications in children.
Main Methods:
- A retrospective cohort study utilizing primary care research databases from 2000 to 2005.
- Inclusion of 675,868 children across three European countries.
- Analysis of drug prescription data, categorizing use by prevalence, recurrence, and off-label status.
Main Results:
- High drug use prevalence (>10/100 children/year) was observed for anti-infective, dermatological, and respiratory drugs.
- Cardiovascular and antineoplastic drugs showed consistently low use (<1/100 children/year).
- Topical steroids, emollients, and asthma medications exhibited high recurrent use; off-label use was common for steroids and antifungals.
Conclusions:
- Significant variations in paediatric drug prescribing exist across European countries.
- The findings provide valuable insights into current paediatric therapeutic practices.
- This data can help prioritize research efforts and improve evidence-based prescribing for children.
Objective:
To provide an overview of drug use in children in three European countries.
Design:
Retrospective cohort study, 2000-5.
Setting:
Primary care research databases in the Netherlands (IPCI), United Kingdom (IMS-DA), and Italy (Pedianet).
Participants:
675 868 children aged up to 14 (Italy) or 18 (UK and Netherlands).
Main Outcome Measure:
Prevalence of use per year calculated by drug class (anatomical and therapeutic). Prevalence of "recurrent/chronic" use (three or more prescriptions a year) and "non-recurrent" or "acute" use (less than three prescriptions a year) within each therapeutic class. Descriptions of the top five most commonly used drugs evaluated for off label status within each anatomical class.
Results:
Three levels of drug use could be distinguished in the study population: high (>10/100 children per year), moderate (1-10/100 children per year), and low (<1/100 children per year). For all age categories, anti-infective, dermatological, and respiratory drugs were in the high use group, whereas cardiovascular and antineoplastic drugs were always in the low use group. Emollients, topical steroids, and asthma drugs had the highest prevalence of recurrent use, but relative use of low prevalence drugs was more often recurrent than acute. In the top five highest prevalence drugs topical inhaled and systemic steroids, oral contraceptives, and topical or systemic antifungal drugs were most commonly used off label.
Conclusion:
This overview of outpatient paediatric prescription patterns in a large European population could provide information to prioritise paediatric therapeutic research needs.
