Insights
Opioid prescriptions for young children frequently contain potentially dangerous overdose quantities. This study found 2.7% of outpatient opioid prescriptions for children 0-36 months exceeded safe dosing, particularly in infants.
Area of Science:
- Pediatric pharmacology
- Medication safety
- Public health
Background:
- Opioid medications are frequently prescribed for outpatient use in children.
- Accurate dosing is critical for pediatric patient safety, especially for potent medications like opioids.
Purpose of the Study:
- To determine the prevalence of potential overdose errors in outpatient opioid prescriptions for young children.
- To identify risk factors associated with these potential overdose errors.
Main Methods:
- Analysis of 11 years of outpatient Medicaid prescription data.
- Comparison of dispensed opioid dose against expected dose based on imputed weights.
- Definition of potential overdose as >110% of the expected dose.
Main Results:
- 59,536 opioid prescriptions for children aged 0-36 months were analyzed.
- 2.7% of these prescriptions contained potential overdose quantities, with an average excess of 48%.
- Infants aged 0-2 months had the highest frequency (8.9%) of potential overdoses.
Conclusions:
- Outpatient opioid prescriptions for infants and young children often contain potentially excessive quantities.
- Younger age is a significant risk factor for potential opioid overdoses in this population.
Objective:
To estimate the frequency of potential overdoses among outpatient opioid-containing prescriptions.
Method:
Using 11 years of outpatient Medicaid prescription data, we compared opioid dose dispensed (observed) versus expected dose to estimate overdose error frequencies. A potential overdose was defined as any preparation dispensed that was >110% of expected based on imputed, 97th percentile weights.
Results:
There were 59 536 study drug prescriptions to children 0 to 36 months old. Overall, 2.7% of the prescriptions contained potential overdose quantities, and the average excess amount dispensed was 48% above expected. Younger ages were associated with higher frequencies of potential overdose. For example, 8.9% of opioid prescriptions among infants 0 to 2 months contained potential overdose quantities, compared with 5.7% among infants 3 to 5 months old, 3.6% among infants 6 to 11 months old, and 2.3% among children >12 months (P < .0001).
Conclusions:
Opioid prescriptions for infants and children routinely contained potential overdose quantities.
