Insights
A state-mandated opioid consent law significantly reduced opioid prescriptions for pediatric genitourinary surgeries. Pain management and emergency visits remained stable, indicating safe opioid use reduction.
Area of Science:
- Pediatric Surgery
- Pain Management
- Public Health Policy
Background:
- Opioid utilization in pediatric surgery is a significant concern.
- Multimodal pain management strategies are crucial for post-operative care.
- State-mandated opioid consent policies aim to curb opioid use.
Purpose of the Study:
- To evaluate the impact of a state-mandated opioid consent policy on opioid utilization.
- To assess changes in multimodal pain management after policy implementation.
- To determine the effect on delayed prescriptions and emergency department visits.
Main Methods:
- Retrospective review of 462 pediatric genitourinary surgeries (August 2015-February 2020).
- Assessed inpatient and outpatient multimodal pain control utilization.
- Analyzed delayed prescriptions and emergency department visits within 30 days post-surgery.
Main Results:
- Opioid prescriptions decreased from 68.4% to 10.7% (p<0.001) post-policy.
- Morphine milligram equivalents per prescription reduced significantly (p<0.001).
- Delayed non-opioid prescriptions, delayed opioid prescriptions, and ED visits remained unchanged.
Conclusions:
- State-mandated opioid consent effectively reduced opioid prescribing for pediatric genitourinary procedures.
- The policy did not negatively impact pain management or lead to increased emergency visits.
- This approach demonstrates a safe method for decreasing opioid utilization in pediatric surgical settings.
Introduction:
We describe the effect of a state mandated opioid consent on opioid utilization and multimodal pain use for major pediatric genitourinary surgeries.
Methods:
All patients who underwent an inpatient pediatric genitourinary surgery at the Children's Hospital of Pittsburgh between August 2015 and February 2020 were identified. Inpatient and outpatient multimodal pain control utilization were assessed. Delayed prescriptions or emergency department visits within 30 days were identified and when applicable referenced against National Surgical Quality Improvement Program data.
Results:
After accounting for a 6-month transition period following policy implementation, 462 major pediatric genitourinary procedures were identified. The frequency of discharge opiate prescriptions decreased from 68.4% prior to the transition period to 10.7% afterward(p<0.001). Morphine milligram equivalents per prescription decreased from 75(IQR 45-150) to 45(IQR 22.5-75)(p<0.001). The rate of delayed non-opioid analgesic prescriptions (6.6% vs 7.4%), delayed opioid prescriptions (1.5% vs 0.3%), or emergency department visits (11.8% vs 12.6%)(p = 0.809) remained unchanged. Data agreed with National Surgical Quality Improvement Program data in 98.5% of cases. After excluding one surgeon who departed after the transition period, regional block utilization did not change from 61/115(53%) to 147/320(45.9%)(p = 0.425).
Conclusions:
A state mandated opioid consent safely reduced opioid utilization for most major pediatric genitourinary surgeries.
Level Of Evidence:
