Prenatal Breastfeeding Education: Impact on Infants With Neonatal Abstinence Syndrome

Academy of Breastfeeding Medicine Clinical Protocol #21: Breastfeeding in the Setting of Substance Use and Substance Use Disorder (Revised 2023)

Background: The Academy of Breastfeeding Medicine (ABM) revised the 2015 version of the substance use disorder (SUD) clinical protocol to review the evidence and provide updated literature-based recommendations related to breastfeeding in the setting of substance use and SUD treatments. Key Information: Decisions around breastfeeding are an important aspect of care during the peripartum period, and there are specific benefits and risks for substance-exposed mother-infant dyads. Recommendations: This protocol provides breastfeeding recommendations in the setting of nonprescribed opioid, stimulant, sedative-hypnotic, alcohol, nicotine, and cannabis use, and SUD treatments. Additionally, we offer guidance on the utility of toxicology testing in breastfeeding recommendations. Individual programs and institutions should establish consistent breastfeeding approaches that mitigate bias, facilitate consistency, and empower mothers with SUD. For specific breastfeeding recommendations, given the complexity of breastfeeding in mothers with SUD, individualized care plans should be created in partnership with the patient and multidisciplinary team with appropriate clinical support and follow-up. In general, breastfeeding is recommended among mothers who stop nonprescribed substance use by the time of delivery, and they should continue to receive ongoing postpartum care, such as lactation support and SUD treatment. Overall, enhancing breastfeeding education regarding substance use in pregnancy and lactation is essential to allow for patient-centered guidance.

Breastfeeding Experiences in Women from Ten States Reporting Opioid Use Before or During Pregnancy: PRAMS, Phase 8

INTRODUCTION

Evidence of opioid use at hospital delivery has increased over the past two decades, increasing risk of neonatal withdrawal. Breastfeeding may improve infant outcomes, but little is known about breastfeeding experiences of women who have a history of opioid use prior to or during pregnancy. This study aimed to determine if self-reported opioid use prior to or during pregnancy impacted breastfeeding, specifically attempt to breastfeed, duration of breastfeeding, assessment of prenatal breastfeeding intention, source of breastfeeding information, and early hospital experiences.

METHODS

Data from ten states (n = 10,550) that evaluated opioid use in the 2016 Pregnancy Risk Assessment Monitoring System survey were included. Weighted univariate and multivariate linear and logistic regression were calculated. The multivariate regression also included adjustment for covariates.

RESULTS

Among the overall sample, 939 participants reported opioid exposure before or during pregnancy. We found no significant difference in breastfeeding attempt. Breastfeeding for at least 6, 10, or 20 weeks was significantly less likely in participants reporting opioid exposure. Exposure correlated with lower odds of skin-to-skin contact, infant being fed in the first hour, exclusive breastfeeding in the hospital, and feeding on demand. Hospital pacifier use was associated with opioid exposure.

CONCLUSION

While we found no difference in breastfeeding attempt, we did observe significant differences in breastfeeding duration and early hospital experiences which may represent modifiable gaps in clinical practice. Future work should focus on optimizing early hospital experiences and support when breastfeeding is clinically indicated.

Increasing usage of mother's own milk in neonates at risk of neonatal abstinence syndrome: MOM-NAS quality improvement initiative

OBJECTIVE

To increase the usage rate of mothers' own milk (MOM) among neonates with prenatal opioid exposure from a baseline average of 47% to an average of 75% over two years.

STUDY DESIGN

Between October 2018 and December 2020, we implemented various Plan-Do-Study-Act cycles that involved engaging providers in postpartum counseling for mothers with opioid dependence, using electronic medical records to track the rate of counseling, providing NAS educational materials to parents, and establishing a rooming-in unit. Our outcome measure was the provision of MOM to eligible neonates, while our process measure was the rate of postpartum counseling.

RESULTS

During this initiative, we witnessed a special cause variation with an increase in the usage rate of MOM from a baseline of 47% to a 27-month average of 85% by December 2020.

CONCLUSION

A series of quality improvement efforts resulted in increased usage of MOM among infants at risk of NAS.

Non-pharmacological care for opioid withdrawal in newborns

BACKGROUND

The prevalence of substance use, both prescribed and non-prescribed, is increasing in many areas of the world. Substance use by women of childbearing age contributes to increasing rates of neonatal abstinence syndrome (NAS). Neonatal opioid withdrawal syndrome (NOWS) is a newer term describing the subset of NAS related to opioid exposure. Non-pharmacological care is the first-line treatment for substance withdrawal in newborns. Despite the widespread use of non-pharmacological care to mitigate symptoms of NAS, there is not an established definition of, and standard for, non-pharmacological care practices in this population. Evaluation of safety and efficacy of non-pharmacological practices could provide clear guidance for clinical practice.

OBJECTIVES

To evaluate the safety and efficacy of non-pharmacological treatment of infants at risk for, or having symptoms consistent with, opioid withdrawal on the length of hospitalization and use of pharmacological treatment for symptom management. Comparison 1: in infants at risk for, or having early symptoms consistent with, opioid withdrawal, does non-pharmacological treatment reduce the length of hospitalization and use of pharmacological treatment? Comparison 2: in infants receiving pharmacological treatment for symptoms consistent with opioid withdrawal, does concurrent non-pharmacological treatment reduce duration of pharmacological treatment, maximum and cumulative doses of opioid medication, and length of hospitalization?

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search CENTRAL (2019, Issue 10); Ovid MEDLINE; and CINAHL on 11 October 2019. We also searched clinical trials databases and the reference lists of retrieved articles for randomized controlled trials (RCTs), quasi-RCTs, and cluster trials.

SELECTION CRITERIA

We included trials comparing single or bundled non-pharmacological interventions to no non-pharmacological treatment or different single or bundled non-pharmacological interventions. We assessed non-pharmacological interventions independently and in combination based on sufficient similarity in population, intervention, and comparison groups studied. We categorized non-pharmacological interventions as: modifying environmental stimulation, feeding practices, and support of the mother-infant dyad. We presented non-randomized studies identified in the search process narratively.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence. Primary outcomes in infants at risk for, or having early symptoms consistent with, opioid withdrawal included length of hospitalization and pharmacological treatment with one or more doses of opioid or sedative medication. Primary outcomes in infants receiving opioid treatment for symptoms consistent with opioid withdrawal included length of hospitalization, length of pharmacological treatment with opioid or sedative medication, and maximum and cumulative doses of opioid medication.

MAIN RESULTS

We identified six RCTs (353 infants) in which infants at risk for, or having symptoms consistent with, opioid withdrawal participated between 1975 and 2018. We identified no RCTs in which infants receiving opioid treatment for symptoms consistent with opioid withdrawal participated. The certainty of evidence for all outcomes was very low to low. We also identified and excluded 34 non-randomized studies published between 2005 and 2018, including 29 in which infants at risk for, or having symptoms consistent with, opioid withdrawal participated and five in which infants receiving opioid treatment for symptoms consistent with opioid withdrawal participated. We identified seven preregistered interventional clinical trials that may qualify for inclusion at review update when complete. Of the six RCTs, four studies assessed modifying environmental stimulation in the form of a mechanical rocking bed, prone positioning, non-oscillating waterbed, or a low-stimulation nursery; one study assessed feeding practices (comparing 24 kcal/oz to 20 kcal/oz formula); and one study assessed support of the maternal-infant dyad (tailored breastfeeding support). There was no evidence of a difference in length of hospitalization in the one study that assessed modifying environmental stimulation (mean difference [MD) -1 day, 95% confidence interval [CI) -2.82 to 0.82; 30 infants; very low-certainty evidence) and the one study of support of the maternal-infant dyad (MD -8.9 days, 95% CI -19.84 to 2.04; 14 infants; very low-certainty evidence). No studies of feeding practices evaluated the length of hospitalization. There was no evidence of a difference in use of pharmacological treatment in three studies of modifying environmental stimulation (typical risk ratio [RR) 1.00, 95% CI 0.86 to 1.16; 92 infants; low-certainty evidence), one study of feeding practices (RR 0.92, 95% CI 0.63 to 1.33; 49 infants; very low-certainty evidence), and one study of support of the maternal-infant dyad (RR 0.50, 95% CI 0.13 to 1.90; 14 infants; very low-certainty evidence). Reported secondary outcomes included neonatal intensive care unit (NICU) admission, days to regain birth weight, and weight nadir. One study of support of the maternal-infant dyad reported NICU admission (RR 0.50, 95% CI 0.13 to 1.90; 14 infants; very low-certainty evidence). One study of feeding practices reported days to regain birth weight (MD 1.10 days, 95% CI 2.76 to 0.56; 46 infants; very low-certainty evidence). One study that assessed modifying environmental stimulation reported weight nadir (MD -0.28, 95% CI -1.15 to 0.59; 194 infants; very low-certainty evidence) and one study of feeding practices reported weight nadir (MD -0.8, 95% CI -2.24 to 0.64; 46 infants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

We are uncertain whether non-pharmacological care for opioid withdrawal in newborns affects important clinical outcomes including length of hospitalization and use of pharmacological treatment based on the six included studies. The outcomes identified for this review were of very low- to low-certainty evidence. Combined analysis was limited by heterogeneity in study design and intervention definitions as well as the number of studies. Many prespecified outcomes were not reported. Although caregivers are encouraged by experts to optimize non-pharmacological care for opioid withdrawal in newborns prior to initiating pharmacological care, we do not have sufficient evidence to inform specific clinical practices. Larger well-designed studies are needed to determine the effect of non-pharmacological care for opioid withdrawal in newborns.

Breastfeeding in Women on Opioid Maintenance Therapy: A Review of Policy and Practice

INTRODUCTION

Opioid use is epidemic in the United States. Opioid use disorder (OUD) in pregnancy, as well as neonatal abstinence syndrome, has quadrupled in the last decade, and opioid maintenance therapy is recommended for pregnant women with OUD. Breastfeeding is an important means of improving outcomes for these vulnerable women and newborns. The purpose of this study was to review current policy on breastfeeding and opioid maintenance therapy, the rates of breastfeeding among women in this population, and facilitators and barriers to implementing policy recommendations.

METHODS

CINAHL, PubMed, the Cochrane Database of Systematic Reviews, Embase, and Web of Science were searched. Inclusion criteria included publication between 2013 and 2018, English language, human only, and original data (except for policy statements). Studies were excluded if they did not report original data and did not examine breastfeeding for women on opioid maintenance therapy.

RESULTS

Eight policy statements and 17 original research studies were identified that met the search criteria. All the policy statements support breastfeeding for women who are stable on opioid maintenance therapy and do not have HIV. Despite this, rates of breastfeeding among women receiving opioid maintenance therapy remain low compared with women in the general population. Results of qualitative research indicates that women on opioid maintenance therapy face numerous barriers to breastfeeding, including misinformation from health care professionals. Quantitative research has only begun to identify interventions to improve breastfeeding outcomes in this population. Research was conducted primarily with white women receiving care at urban health care centers.

DISCUSSION

Practice lags behind policy in terms of supporting breastfeeding in women receiving opioid maintenance therapy. There is a need for more research that includes African American and rural women on opioid maintenance therapy, as well as quantitative research that uses findings from qualitative research to identify the best possible interventions for improving breastfeeding outcomes for women on opioid maintenance therapy and their newborns. One significant need is for health care provider education regarding these policies as well as best practices for providing breastfeeding education and support to this population.

Maternal breast milk feeding and length of treatment in infants with neonatal abstinence syndrome

OBJECTIVE

The objective of this study is to assess whether infants with neonatal abstinence syndrome (NAS), who receive maternal breast milk (BM), have shorter pharmacological treatment durations and lengths of stay compared with formula-fed infants.

STUDY DESIGN

Retrospective data analysis from Optum Neonatal Database for infants born between 1 January 2010 and 21 November 2016, who received treatment for NAS. Clinical characteristics and outcomes were compared between infants who received any amount of BM and those exclusively formula-fed.

RESULT

Infants (1738) were analyzed. Median length of pharmacological treatment was significantly lower in infants who received any BM (14 days) compared with "no BM" group (17 days, p = 0.04). Similarly, median length of hospitalization was significantly reduced in "any BM" group (19 days vs. 20 days), which remained significant after adjustment for confounders (p = 0.01). There was no difference in hospital re-admission rates.

CONCLUSION

Feeding any BM to infants with NAS was associated with both decreased lengths of pharmacological treatment and hospital stay compared with exclusively formula-fed infants.

Breastfeeding Intention Compared With Breastfeeding Postpartum Among Women Receiving Medication-Assisted Treatment

BACKGROUND:

Women taking methadone or buprenorphine are encouraged to breastfeed if stable without polysubstance use.

RESEARCH AIM:

We aimed to determine the difference between stated intention to breastfeed prenatally in women taking methadone or buprenorphine compared with breastfeeding at discharge and 2 months postpartum. Secondary outcomes were determining whether breastfeeding was more common in women taking buprenorphine, in women without hepatitis C infection, and in women without a history of heroin use, and whether breastfeeding reduced the need for pharmacological treatment of neonatal opioid withdrawal syndrome.

METHODS:

This was a retrospective cohort study of 228 women enrolled in a perinatal substance abuse treatment program. Electronic medical records were reviewed to abstract data on mother-infant dyads. Chi-square tests were used to analyze our outcomes.

RESULTS:

Women taking buprenorphine had a higher prevalence of breastfeeding compared with women taking methadone (83% [ n = 100] vs. 71% [ n = 76]; χ² = 4.35, p = .03), despite no difference in their prenatal intention to breastfeed (87% vs. 81%; χ² = 1.28, p = .25). Only 31% ( n = 38) of women taking buprenorphine and 19.6% ( n = 21) of women taking methadone exclusively breastfed at discharge (χ² = 5.43, p = .06). Exclusively breastfed infants required less pharmacological treatment for neonatal opioid withdrawal syndrome compared with formula-fed infants (15.8% [ n = 21] vs. 47.4% [ n = 38]; χ² = 19.72, p < .05).

CONCLUSION:

Despite most women reporting a high prenatal intention to breastfeed, exclusive breastfeeding at hospital discharge postpartum was low. Breastfeeding was associated with a decreased likelihood of pharmacological treatment for neonatal opioid withdrawal syndrome.

Examination of Hospital, Maternal, and Infant Characteristics Associated with Breastfeeding Initiation and Continuation Among Opioid-Exposed Mother-Infant Dyads

OBJECTIVES

Among opioid-exposed newborns, breastfeeding is associated with less severe withdrawal signs, yet breastfeeding rates remain low. We determined the extent to which hospital, maternal, and infant characteristics are associated with breastfeeding initiation and continuation among opioid-exposed dyads.

MATERIALS AND METHODS

We examined breastfeeding initiation and continuation until infants' discharge among opioid-exposed dyads from 2006 to 2016. Among dyads meeting hospital breastfeeding guidelines, we assessed hospital (changes in breastfeeding guidelines and improvement initiatives [using delivery year as a proxy]), maternal (demographics, comorbid conditions, methadone versus buprenorphine treatment, and delivery mode), and infant (gestational age and birth weight) characteristics. We used multivariable logistic regression to examine independent associations of characteristics with breastfeeding initiation and continuation.

RESULTS

Among 924 opioid-exposed dyads, 61% (564) met breastfeeding criteria. Overall, 50% (283/564) of dyads initiated and 33% (187/564) continued breastfeeding until discharge. Breastfeeding initiation and continuation rates increased from 38% and 8% in 2006, to 56% and 34% in 2016, respectively. In adjusted models, infants born after reducing restrictions in hospital breastfeeding guidelines and prenatal breastfeeding education (adjusted odds ratio, aOR 2.6 [95% confidence interval, CI 1.5-4.5]) had increased odds of receiving any maternal breast milk versus infants born with earlier hospital policies. Cesarean versus vaginal delivery (aOR 0.3 [95% CI 0.2-0.6]) and length of infant hospitalization (aOR 0.94 [95% CI 0.92-0.97]) were negatively associated with breastfeeding continuation.

CONCLUSIONS

Despite increasing breastfeeding rates among opioid-exposed dyads, rates remain suboptimal. Hospital-level factors were the greatest predictor of breastfeeding initiation. The findings suggest that changes in hospital guidelines and initiatives can impact breastfeeding initiation among this vulnerable population.
