Objective. To determine whether an
educational video could improve parent knowledge, beliefs, and
behaviors about the appropriate use of oral antibiotics.
Study Design. A randomized, controlled trial was conducted
in an urban primary care clinic and a suburban pediatric practice.
Parents were randomly assigned to the intervention or control groups.
Parents in the intervention group were asked to view a 20-minute video, specifically developed for this project, over a 2-month period, and
given a brochure about antibiotics. Parent knowledge, beliefs, and
behaviors were assessed at the time of enrollment and then by telephone
2 months later.
Results. A total of 193 (94%) of 206 parents completed
the study. The groups were equivalent with respect to all important
baseline characteristics. No differences were found for adjusted
posttest means between the intervention and control groups for
knowledge, beliefs, or behavior. For example, the intervention group
scored 8.04 on the knowledge questionnaire (11 true-false questions), compared with 7.82 for the control group. Subgroup analysis, based on
site of enrollment, indicated that families in the intervention group
from the primary care urban clinic improved their knowledge score (6.03 to 6.92) and were more likely to report that there were problems with
children receiving too many antibiotics (intervention 67% vs control
34%).
Conclusion. Overall, this video had only a modest effect
on parent knowledge, beliefs, and self-reported behaviors regarding
oral antibiotics. We believe that any campaign promoting the judicious
use of oral antibiotics must use a multifaceted approach and target
both parents and physicians.
