Newborn birth-weight of pregnant women on methadone or buprenorphine maintenance treatment: A national contingency management approach trial

A qualitative exploration of the eight dimensions of wellness in opioid use disorder recovery during the postpartum period

Background

Recovery from opioid use disorder (OUD) during the perinatal period has unique challenges. We examined services for perinatal women with OUD using the Substance Abuse and Mental Health Services Administration (SAMHSA) eight dimensions of wellness (DoW), which reflect whole person recovery.

Methods

We enrolled professionals from the Southwestern United States who work with people with OUD during the perinatal period. Semi-structured in-depth interviews were conducted from April to December 2020. Participants were shown the DoW diagram (emotional, social, environmental, physical, financial, spiritual, occupational, intellectual) and asked to share how their clinic/agency addresses each DoW for perinatal people with OUD. Responses were transcribed and coded by two researchers using Dedoose software.

Results

Thematic analysis revealed ways professionals (n = 11) see how the services they provide fit into the DoW. This included: the need to provide mothers emotional support with a nonjudgmental approach, groups providing social support; guidance on nutrition, self-care, and a focus on the mother/infant dyad; assistance with employment and activities of daily living; parenting education; connecting mothers with resources and grants; providing a variety of spiritual approaches depending on the desire of the mother; and navigating the interpersonal environment as well as the physical space.

Conclusions

There are opportunities to expand the treatment and services provided to women with OUD during the perinatal period within all eight DoWs. Additional research is needed to identify effective strategies to incorporate these components into patient-centered, holistic care approaches.

Trend differences over 20 years between two methadone maintenance clinics, one with and one without cannabis legalization

BACKGROUND

Although methadone maintenance treatment (MMT) guidelines are well established, patients' characteristics and outcome change over time may be affected by the legality of cannabis.

OBJECTIVE

To study trend changes between two clinics over 20 years from Las Vegas (LV) and 27 years from Tel Aviv (TA).

METHODS

Patients' characteristics at admission, including drugs in urine at first and 13th month were obtained from their medical charts. Changes by year of admission and cumulative retention were analyzed.

RESULTS

The LV MMT clinic (1724 patients) had a lower one-year retention rate compared to the TA MMT clinic (1014 patients) (46.4% vs. 74.4%, respectively, p < 0.0005), and a higher rate of opioid stop after one year (75.9% vs. 68.8%, respectively, p = 0.003). The age at MMT admission and the retention rates decreased in LV and increased in TA. The prevalence of cannabis and benzodiazepine misuse on MMT admission increased in LV with no change recorded in TA. Cocaine on MMT admission decreased in LV and increased in TA, while amphetamine use increased in LV and decreased in TA. Cox models multivariate analyses found cannabis on admission to predict shorter retention in LV (as younger age male and amphetamines), and cannabis after one year in TA (as did cocaine and opiates after one year and BDZ on admission).

CONCLUSION

Although cannabis prevalence increased only in LV where it was legalized, it was associated with poor outcomes in both clinics. Younger age, a known poor outcome predictor, may be related to decreased retention in LV.

Opioid Use in Pregnancy

PURPOSE OF REVIEW

Perinatal opioid use is a major public health problem and is associated with a number of deleterious maternal and fetal effects. We review recent evidence of perinatal outcomes and treatment of opioid use disorder (OUD) during pregnancy.

RECENT FINDINGS

Opioid exposure in pregnancy is associated with multiple obstetric and neonatal adverse outcomes, with the most common being neonatal opioid withdrawal syndrome (NOWS). Treatment with buprenorphine or methadone is associated with NOWS, but neither medication appears to have significant adverse effects on early childhood development. Buprenorphine appears to be superior to methadone in terms of incidence and severity of NOWS in exposed infants. The long-term effects of opioid exposure in utero have been inconclusive, but recent longitudinal studies point to potential differences in brain morphology that may increase vulnerability to future stressors. Maintenance therapy with methadone or buprenorphine remains the standard of care for pregnant women with OUD given its consistent superiority to placebo in terms of rates of illicit drug use and pregnancy outcomes. New non-pharmacologic management options for NOWS appear promising. Future research is needed to further evaluate the effects of opioid exposure in utero and determine the optimal delivery model for maintenance therapy.

Neonatal outcomes after fetal exposure to methadone and buprenorphine: national registry studies from the Czech Republic and Norway

BACKGROUND AND AIMS

Opioid maintenance treatment (OMT) is recommended to opioid-dependent females during pregnancy. However, it is not clear which medication should be preferred. We aimed to compare neonatal outcomes after prenatal exposure to methadone (M) and buprenorphine (B) in two European countries.

DESIGN

Nation-wide register-based cohort study using personalized IDs assigned to all citizens for data linkage.

SETTING

The Czech Republic (2000-14) and Norway (2004-13). [Correction added after online publication on 26 April 2018: The Czech Republic (2000-04) corrected to (2000-14).] PARTICIPANTS: Opioid-dependent pregnant Czech (n = 333) and Norwegian (n = 235) women in OMT who received either B or M during pregnancy and their newborns.

MEASUREMENTS

We linked data from health registries to identify the neonatal outcomes: gestational age, preterm birth, birth weight, length and head circumference, small for gestational age, miscarriages and stillbirth, neonatal abstinence syndrome (NAS) and Apgar score. We performed multivariate linear regression and binary logistic regression to explore the associations between M and B exposure and outcomes. Regression coefficient (β) and odds ratio (OR) were computed.

FINDINGS

Most neonatal outcomes were more favourable after exposure to B compared with M, but none of the differences was statistically significant. For instance, in the multivariate analysis, birth weight was β = 111.6 g [95% confidence interval (CI) = -10.5 to 233.6 and β = 83.1 g, 95% CI = -100.8 to 267.0] higher after B exposure in the Czech Republic and Norway, respectively. Adjusted OR of NAS for B compared with M was 0.94 (95% CI = 0.46-1.92) in the Norwegian cohort.

CONCLUSIONS

Two national cohorts of women receiving opioid maintenance treatment during pregnancy showed small but not statistically significant differences in neonatal outcomes in favour of buprenorphine compared with methadone.
