Insights
This study found that the duration of an initial opioid prescription for children did not affect their likelihood of receiving a repeat prescription. Nearly 10% of pediatric patients refilled their opioid medication after acute pain treatment.
Area of Science:
- Pediatric pharmacology
- Pain management
- Public health
Background:
- Opioid prescriptions for children are common for acute pain.
- Understanding factors influencing repeat opioid prescriptions is crucial for managing pediatric opioid use and potential misuse.
Purpose of the Study:
- To evaluate the association between the duration of an initial opioid prescription and the likelihood of a child receiving a subsequent (repeat) opioid prescription.
- To inform clinical guidelines and public health strategies regarding pediatric opioid prescribing.
Main Methods:
- A retrospective cohort study analyzed Medicaid Managed Care data from 2013-2018.
- Included were 17,086 children (ages 1-17) with an incident opioid prescription (no opioid use in the prior 12 months).
- Logistic regression modeled the association between initial opioid prescription duration (1-3, 4-7, 8-10, >10 days) and repeat prescriptions within 30 days.
Main Results:
- 10.4% of children (1780/17086) received a repeat opioid prescription.
- Initial opioid prescription durations of 4-7 days, 8-10 days, and >10 days were not significantly associated with an increased likelihood of receiving a repeat prescription compared to 1-3 days' supply.
- Adjusted odds ratios (aOR) for repeat prescriptions were comparable across all initial supply durations.
Conclusions:
- Initial opioid prescription duration does not appear to be a significant predictor of receiving a repeat opioid prescription in children treated for acute pain.
- These findings suggest that focusing on initial opioid prescription length alone may not be sufficient to prevent repeat opioid use in pediatric populations.
- Further research should explore other factors contributing to repeat opioid prescriptions in children.
Objective:
Our study evaluated the association between initial opioid prescription duration and receipt of a repeat opioid prescription in children.
Methods:
Eligible individuals were children between 1 and 17 years of age who enrolled in a Medicaid Managed Care plan and filled an incident opioid prescription during 2013 to 2018. An incident prescription was defined as receipt of an opioid analgesic without a prior use for 12 months. A repeat opioid prescription was defined as receipt of a subsequent opioid prescription within 30 days since the end of incident opioid prescription. A hierarchical multivariable logistic regression model was fitted to test the association between incident opioid prescription duration and the likelihood of receiving a repeat prescription.
Results:
The cohort consisted of 17,086 children receiving an incident opioid prescription in which 6272 (36.7%) received 1 to 3 days' supply, 8442 (49.4%) received 4 to 7 days' supply, 1434 (8.4%) received 8 to 10 days' supply, and 938 (5.5%) received >10 days' supply. Of these incident opioid recipients, 1780 (10.4%) filled a repeat opioid prescription. The multilevel model results indicated that, children receiving 4 to 7 days' supply (adjusted odds ratio [aOR]: 0.98 {0.9-1.1}), 8 to 10 days' supply (aOR: 1.03 [0.8-1.3]), and >10 days' supply (aOR: 0.85 [0.7-1.1]) had comparable likelihoods of receiving a repeat prescription as those receiving 1 to 3 days' supply.
Discussion:
Nearly 10% of children who filled an opioid prescription for acute pain received a repeat prescription. Initial prescription duration was not associated with the risk of receiving a repeat prescription.
