Autonomous Care Pathway to Patient Opioid Abstinence: Should All Programs Offer this Approach?

Abstract

Introduction: The opioid epidemic resulted in vast increase in neonatal opioid withdrawal syndrome (NOWS). To mitigate NOWS and opioid dependency among women, staff established a gender specific, patient driven, autonomy based, outpatient therapeutic substitution program.

Methods: Prospective observational study of obstetric patients receiving prenatal care 7/1/2016-12/31/2019. Patients underwent universal urine drug screens to identify illicit drug use with dependency and offered addiction counseling with voluntary outpatient therapeutic substitution in an obstetrical-addictions combined clinic to achieve abstinence with oral Buprenorphine tapering protocol. Urine substance screening and cord blood testing were obtained at delivery. Birth outcomes compared among groups who achieved abstinence at birth, were successful at tapering, or continued opioid use.

Results: Of 783 births, 165 (20.9%) demonstrated opioid use with 91 (55.2%) participating at some point in pregnancy in therapeutic substitution program. At birth, 14/94 (14.9%) patients completed the program and achieved opioid abstinence, 22/94 (23.4%) still enrolled and actively tapering. 57/94 (34.5%) patients were lost to follow-up, relapsed, or terminated due to non-compliance. Seventy-four of 67 (44.3%) opioid positive mothers chose not to enroll. Of 14 women who completed the program, 0 babies born with NOWS, compared to 11/22 (50%) still enrolled in program and actively tapering, 29/57 (50.9%) lost to follow-up, relapsed, or terminated due to non-compliance, and 28/74 (37.8%) never enrolled in program.

Conclusion/implications: Outpatient therapeutic substitution with oral Buprenorphine with abstinence is possible in pregnant patients and results zero NOWS. More data are needed to confirm findings and explore methods for enhanced success in obtaining abstinence.
