Opioids are generally an inappropriate acute pain management strategy in children, particularly because of the risk for diversion and subsequent misuse and abuse. To examine associations between Medicaid plan type [coordinated care organization (CCO), managed care (MC), fee-for-service (FFS)] and whether a child received an opioid prescription. Secondary analysis of Oregon Medicaid data (January 1, 2016 to December 31, 2017). Medicaid-enrolled children ages 0-17 (N=200,169). There were 2 outcomes: whether a child received an opioid prescription from (a) any health provider or (b) from a visit to the dentist. Predictor variables included Medicaid plan type, age, sex, race, and ethnicity. About 6.7% of children received an opioid from any health provider and 1.2% received an opioid from a dentist visit. Children in a CCO were significantly more likely than children in a MC (P<0.01) or FFS (P=0.02) plan to receive an opioid from any health provider. Children in a CCO were also significantly more likely than children in MC or FFS to receive an opioid from a dentist visit (P<0.01). Pediatric opioid prescriptions vary by plan type. Future efforts should identify reasons why Medicaid-enrolled children in a CCO plan are more likely to be prescribed opioids.
