Parental knowledge about antibiotic use: results of a cluster-randomized, multicommunity intervention

Area of Science:

• Public Health
• Pediatrics
• Health Education

Background:

• Parental misconceptions contribute to pediatric antibiotic overprescribing.
• Targeted educational interventions are crucial for improving antibiotic stewardship.

Purpose of the Study:

• To assess the impact of a community-wide educational intervention on parental knowledge and attitudes regarding pediatric antibiotic use.
• To determine if the intervention could decrease unnecessary antibiotic prescribing in children under 6 years old.

Main Methods:

• A 3-year cluster-randomized trial was conducted in 16 Massachusetts communities.
• Parents in intervention communities received educational newsletters and materials via pediatric providers, pharmacies, and child care centers.
• Mailed surveys before (2000) and after (2003) the intervention compared knowledge and attitudes between intervention and control groups.

Main Results:

• Parental knowledge scores improved in both intervention and control communities between 2000 and 2003.
• No significant overall intervention effect on knowledge of appropriate antibiotic use was detected.
• A significant intervention effect was observed in parents of Medicaid-insured children, who had lower baseline knowledge.

Conclusions:

• While knowledge on antibiotic use is improving generally, targeted educational interventions are beneficial for specific populations, such as parents of Medicaid-insured children.
• Findings suggest a need for tailored health education campaigns to promote judicious antibiotic use.
• Socially advantaged populations may not require additional targeted interventions for improved antibiotic knowledge.
