Opioid Dosing Deviation and Dose Banding Development in Young Hospitalized Children

Area of Science:

• Pediatric pharmacology
• Patient safety
• Medication management

Background:

• Individualized, weight-based opioid dosing in children presents safety concerns and process inefficiencies.
• Dose banding, a patient safety strategy, standardizes doses by weight ranges to minimize dosing errors.

Purpose of the Study:

• To assess the frequency of dosing deviations for common intravenous (IV) and oral opioids in hospitalized children.
• To analyze how dosing deviations differ across pediatric age groups.
• To evaluate the potential reduction in dose variation achievable through dose banding.

Main Methods:

• A cross-sectional analysis of 3361 opioid doses administered to hospitalized children aged 2 months to 24 months.
• Categorization of dosing deviations: within ±5% (no deviation), >5% below (negative), and >5% above (positive) reference ranges.
• Descriptive and bivariate statistical analyses were employed.

Main Results:

• 79.2% of doses were within the reference range, while 6.3% were below and 14.4% were above.
• Dosing deviations varied by age: more frequent in younger children for oral opioids and in older children for IV morphine.
• Dose banding could potentially decrease unique prescribed doses by 75% and eliminate unintended deviations.

Conclusions:

• Approximately 20% of opioid doses for children up to 24 months fall outside recommended therapeutic ranges.
• Dose banding shows promise as a strategy to simplify opioid prescribing and enhance safety in pediatric inpatient settings.
