Postpartum Persistent Opioid Use After Opioid Exposure for Childbirth

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Pharmacology

Background:

• Opioid use during the childbirth period is common for pain management.
• Understanding the long-term consequences of this exposure is crucial for patient safety.
• Persistent postpartum opioid use poses significant health risks.

Purpose of the Study:

• To examine the association between opioid exposure around childbirth and persistent postpartum opioid use.
• To investigate if specific opioid medications are linked to higher risks of long-term use.
• To identify risk factors for sustained opioid use after delivery.

Main Methods:

• Retrospective cohort study using Pennsylvania Medicaid claims (2015-2021).
• Included women aged 19-50 with vaginal or cesarean delivery and continuous Medicaid enrollment.
• Defined exposure as filled opioid prescriptions during the childbirth period (7 days pre-delivery to 8 weeks postpartum).
• Defined persistent postpartum opioid use as opioid use disorder diagnosis or repeated opioid prescriptions from 8 weeks to 14 months postpartum.

Main Results:

• Childbirth opioid exposure was present in 25% of births; 5.7% experienced persistent postpartum opioid use.
• Patients with childbirth opioid exposure had a 1.88 times higher odds of persistent postpartum use compared to unexposed individuals.
• Among opioid-naïve individuals, childbirth opioid exposure increased the odds of persistent use by 2.66 times.
• Tramadol exposure was associated with the highest risk of persistent use (30.9%) compared to oxycodone (7.3%).

Conclusions:

• Opioid use for childbirth pain management is significantly associated with persistent postpartum opioid use.
• This association holds true for opioid-naïve patients and those without pre-existing pain conditions.
• Findings emphasize the need for careful pain management strategies balancing efficacy with opioid risk minimization and improved postpartum care coordination.
