Filled Opioid Prescriptions Following Pediatric Dental Procedures Among Medicaid-Insured Children in Ohio

Purpose: To investigate opioid prescription fills following pediatric/adolescent dental procedures in central/southeastern Ohio. Methods: This population-based, retrospective cohort study utilized health insurance claims from a pediatric public accountable care organization (???Medicaid???) in central/southeastern Ohio. Patients aged 18 years and younger who had a dental procedure between January 2012 and February 2019 were identified, and claims were searched for opioid prescription fills within 14 days post-procedure. Trends in prescription fill percentages, types of opioid, procedure classification and patient characteristics were examined. Results: A total of 512,922 encounters among 212,813 patients were included. The overall opioid prescription fill was 4.9 percent. Percentages decreased throughout the study period from 6.1 percent (95 percent confidence interval [95% CI]=5.9 to 6.3) in 2012 to 3.4 percent (95% CI=3.1 to 3.8) in early 2019. When limited to extractions and endodontic procedures, the overall prescription fill percentage fell from 15.7 percent (95% CI=15.2 to 16.1) in 2012 to 9.5 percent (95% CI=8.5 to 10.4) in early 2019. The most common opioids were hydrocodone (68.6 percent) and codeine (24.7 percent), with marked annual reductions in codeine prescription fills among children younger than 14 years. From 2017 to 2018, surgical extractions compared to endodontics-only procedures (risk difference [RD]=40.7; 95% CI=38.6 to 42.9) and older patient age (RD for 18-year-olds versus 13-year-olds=21.9; 95% CI=19.8 to 24.0) were strong risk factors for filling an opioid prescription. Conclusion: Post-procedure opioid prescription fill percentages have decreased since 2012 among pediatric/adolescent Medicaid enrollees undergoing dental procedures in central/southeastern Ohio. Substantial differences in the likelihood of filling a prescription remained by procedural and demographic variables. There were marked trends in the types of opioid for which prescriptions were filled, which varied by patient age.
