Perinatal OUD Continuity & Retention

Drug overdose is now a leading cause of pregnancy-associated death, with rates rising from 6.9 to 12.2 per 100,000 mothers between 2018 and 2021. More than 60% of these deaths occur outside healthcare settings, peaking at 7–12 months postpartum.

  • 64.1% of women maintained MOUD for the full 12 months postpartum in Massachusetts cohort
  • Only 34% continuation if MOUD initiated in final month before delivery vs 80% for full pregnancy
  • 12-month Medicaid extension increases MOUD months by 8.55%
  • MOUD is the only factor consistently associated with reduced postpartum overdose

Epidemiology

Opioid use disorder during pregnancy has escalated dramatically:

Critical Window: The postpartum period (especially 7-12 months) represents peak overdose risk. Treatment discontinuation and loss of physiologic tolerance converge to create lethal vulnerability.

Predictors of MOUD Retention

Handoff Failure Points

Transition Failure Mechanism Consequence
Prenatal → L&D MOUD dose not communicated; pain plan absent Undertreated pain → AMA discharge; precipitated withdrawal
L&D → Postpartum Inconsistent MOUD continuation orders Missed doses; early discharge
Hospital → Home (0-14 days) No warm handoff to outpatient MOUD prescriber Highest vulnerability; loss to follow-up
6 Weeks → 6 Months Medicaid ended at 60 days; no OUD-specific follow-up Insurance loss; emerging postpartum depression
6-12 Months → Primary Care Pediatric visits continue but maternal OUD follow-up lapses Peak overdose window without safety net

Care Models Comparison

Model Key Features Retention Evidence
Co-located OB–Addiction Clinic Single site: OB + addiction medicine + mental health + social work 69% at 6 months; fewer missed postpartum appointments
Low-Threshold Bridge Buprenorphine Same-day/next-day buprenorphine start; no service prerequisites "Medication First" doubles treatment entry
OTP Linkage Daily dosing; structure and accountability Methadone ≥60 mg improves retention
Tele-MOUD Video/phone buprenorphine initiation and maintenance 48% vs 44% 90-day retention; 3.8% vs 9.7% 6-mo discontinuation
Peer Recovery Support Certified peer specialists embedded in clinical/community settings Nearly doubles MOUD acceptance at warm handoff

Policy Environment Effects

Punitive policies (criminalization, civil commitment): Associated with 43% higher odds of no planned MOUD; 45% increase in opioid overdoses among pregnant women; significantly greater NAS rates.
Supportive policies (treatment funding, Medicaid extension): Implementation increased MOUD receipt by 11%; decreased opioid overdoses by 45%.
