Insights
Antibiotic prescribing and consultations for respiratory infections decreased most in school-aged children. Reductions varied by age group, with the greatest declines seen in younger populations for both consultations and antibiotic prescriptions.
Area of Science:
- General Practice Research
- Pediatric Infectious Diseases
- Antimicrobial Stewardship
Background:
- Global data show declining acute respiratory infection (ARI) consultations and antibiotic prescriptions.
- Age-specific trends in ARI consultations and antibiotic prescribing are not well understood.
Purpose of the Study:
- To analyze age-specific changes in consultation rates for ARIs.
- To determine how antibiotic prescribing reductions varied by age for different respiratory infections.
Main Methods:
- Utilized data from the UK General Practice Research Database (108 practices).
- Estimated age-specific changes between 1995-2000 in consultation rates and antibiotic prescription proportions.
- Analyzed data for 'all respiratory infections', 'sore throat', 'ear infection', 'bronchitis', and 'chest infection'.
Main Results:
- Consultation rates for ARIs decreased across all age groups, with the largest drops in children (1-16 years).
- Antibiotic prescribing reductions were most significant in children (1-16 years), especially for sore throats.
- The greatest relative reduction in antibiotic prescribing was observed in 5-10 year olds for sore throats (32%).
Conclusions:
- School-aged children showed the largest decrease in ARI consultations.
- Preschool and school-aged children experienced the greatest reductions in antibiotic prescribing.
- The reasons for these rapid changes in consultation rates remain unexplained.
Background:
International studies using data aggregated for all ages have shown decreasing rates of general practice consultations for acute respiratory infections with fewer antibiotic prescriptions issued per consultation. The occurrence of different respiratory infections varies widely at different ages but we do not know whether prescribing has reduced equally in all age groups.
Objective:
We aimed to determine how reductions in consultation rates and antibiotic prescribing varied with age for different respiratory infections.
Methods:
Data were abstracted from the General Practice Research Database for 108 general practices in the UK (mean registered population 642 685). We estimated age-specific changes between 1995 and 2000 in consultation rates, and the proportion of consultations resulting in an antibiotic prescription for 'all respiratory infections' and for 'sore throat', 'ear infection', 'bronchitis' and 'chest infection'.
Results:
Consultation rates for 'all respiratory infections' declined in all age groups with the greatest decreases in children aged 1-4 years (41%), 5-10 year olds (53%) and 11-16 year olds (54%), whereas at 75-84 years the reduction was 28%. The pattern of greater reductions in children held for each separate condition even though the age of peak incidence varied. The relative reduction in antibiotic prescribing was greatest at 1-4 years (18%), 5-10 years (17%) and 11-16 years (17%), compared with 5% at 75-84 years. Antibiotic prescribing decreased most for sore throat and this was observed at all ages particularly in 5-10 year olds (relative reduction, 32%).
Conclusions:
School age children account for the greatest reduction in consultations for acute respiratory infection. School age and preschool children account for the greatest reductions in antibiotic prescribing during the consultation. The rapid changes in consultation rates are unexplained.

Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
