OBJECTIVE: Developing, implementing, and evaluating the effectiveness of outpatient pediatric antimicrobial stewardship interventions via tele-stewardship.
DESIGN: Baseline data collected between January and December 2022. Intervention data collected from February 2023 to December 2024. Interrupted time series with regression discontinuity analysis used to compare rates of antibiotic prescription between the periods.
SETTING: Three pediatric primary care clinics and three emergency departments associated with Vanderbilt University Medical Center that served rural and suburban communities.
PARTICIPANTS: All encounters with patients less than 18 years of age at participating sites.
INTERVENTIONS: Intervention bundle included patient/caregiver educational materials, antibiotic use commitment posters, prescriber education through quarterly teaching sessions on common pediatric infections, communication skills training, app-based microlearning modules, access to local guidelines using the Firstline app, and quarterly audit and feedback with peer comparison on guideline-concordant antibiotic use.
RESULTS: Among a total of 147,357 encounters (43,157 baseline, 100,200 intervention), overall percent of encounters with one or more antibiotics prescribed decreased from 12.4% to 11.9% (P = .01). Percent change varied by site and patient demographics. Overall guideline-concordant prescribing increased significantly for acute otitis media (77.7% baseline vs 85.7% intervention, P < .001), streptococcal pharyngitis (73.8% baseline vs 81.7% intervention, P < .001), and urinary tract infections (41.9% baseline vs 57.1% intervention P < .001). Five-day antibiotic courses increased significantly (6.3% baseline vs 19.7% intervention, P < .001). There was a significant decrease in rapid streptococcal testing (10.9% baseline vs 7.6% intervention, P < .001).
CONCLUSIONS AND RELEVANCE: Tele-stewardship interventions were effective in outpatient pediatric primary care and emergency department settings, but effectiveness varied by site.
