Insights
Physicians are more likely to prescribe antibiotics for children with upper respiratory tract infections (URI) if the child appears unwell, has a high fever, or is over two years old. These clinical factors influence antibiotic prescribing for pediatric URI.
Area of Science:
- Pediatrics
- Infectious Diseases
- Clinical Practice
Background:
- Antibiotic misuse for viral upper respiratory tract infections (URI) in children is a significant global health concern.
- Over-prescription contributes to antibiotic resistance and adverse effects.
Purpose of the Study:
- To determine the influence of specific clinical features on antibiotic prescribing for pediatric URI.
- To investigate factors that may increase physician concern about bacterial infection in children with URI.
Main Methods:
- A mail survey with 16 clinical scenarios of children with URI was distributed to 540 pediatricians and family practitioners in Ontario, Canada.
- Logistic regression analysis was used to assess the association between clinical features, parental pressure, and physician characteristics with antibiotic prescribing.
Main Results:
- Poor appearance (OR, 6.50), fever >38.5°C (OR, 1.48), and age >2 years (OR, 2.27) were significantly associated with antibiotic prescribing.
- Parental pressure was not associated with antibiotic prescribing.
- Physician factors like being a family practitioner (OR, 1.54), seeing more patients weekly, and older physician age were linked to higher antibiotic use.
Conclusions:
- Clinical indicators of potential bacterial infection in children with URI are associated with increased antibiotic prescribing.
- Understanding these physician decision-making factors is crucial for developing targeted interventions to reduce antibiotic misuse.
Objectives:
Antibiotic misuse for viral upper respiratory tract infections (URI) in children is a significant problem. We determined the influence on antibiotic prescribing of clinical features that may increase concern about possible bacterial infection (age, appearance, fever) in children with URI.
Study Design:
We created 16 scenarios of children with URI and distributed them by mail survey to 540 pediatricians and family practitioners in Ontario, Canada. The association of patient clinical features, parental pressure, and physician characteristics with antibiotic prescribing was determined through the use of logistic regression analysis.
Results:
A total of 257 physicians responded (48%). Poor appearance (OR, 6.50; 95% CI, 5.06 to 3.84), fever above 38.5 degrees C (OR, 1.48; 95% CI, 1.21 to 1.82), and age older than 2 years (OR, 2.27; 95% CI, 1.85 to 2.78) were associated with prescribing, whereas parental pressure was not. Physician characteristics associated with antibiotic use were family practitioner (OR, 1.54; 95% CI, 1.22 to 1.96), increasing number of patients seen per week (OR, 1.05; 95% CI, 1.01 to 1.08 for every 20-patient increase), and increasing physician age (OR, 1.17; 95% CI, 1.11 to 1.24, 5-year increments).
Conclusions:
Clinical factors, which may lead physicians to be concerned about possible bacterial infection in children, are associated with antibiotic use for pediatric URI.
