BACKGROUND AND OBJECTIVES: Updated guidelines continue to support watchful waiting as an option for uncomplicated acute otitis media (AOM) and provide explicit diagnostic criteria. To determine treatment prevalence and associated determinants of watchful waiting for AOM in commercially insured pediatric patients. METHODS: This was a retrospective cohort study using IBM Marketscan Commercial Claims Databases (2005 to 2019) of patients 1 to 12 years old with AOM, without otitis-related complications within 6 months prior, with no tympanostomy tubes, and no other infections around index diagnosis of AOM. We examined monthly antibiotic treatment prevalence (defined as pharmacy dispensing within 3 days of AOM diagnosis) and used multivariable logistic regression models to examine determinants of watchful waiting. RESULTS: Among 2 176 617 AOM episodes, 77.8% were treated within 3 days. Whereas some clinical characteristics were moderate determinants for watchful waiting, clinician antibiotic prescribing volume and specialty were strong determinants. Low-volume antibiotic prescribers (≥80% of AOM episodes managed with watchful waiting) had 11.61 (95% confidence interval 10.66-12.64) higher odds of using watchful waiting for the index AOM episode than high-volume antibiotic prescribers ($80% treated). Otolaryngologists were more likely to adopt watchful waiting (odds ratio 5.45, 95% CI 5.21-5.70) than pediatricians, whereas other specialties deferred more commonly to antibiotics. CONCLUSIONS: Adoption of watchful waiting for management of uncomplicated, nonrecurrent AOM was limited and stagnant across the study period and driven by clinician rather than patient factors. Future work should assess motivators for prescribing and evaluate patient outcomes among clinicians who generally prefer versus reject watchful waiting approaches to guide clinical decision-making.
