Retrospective study found that outpatient care for infants exposed to drugs during pregnancy was sustainable and safe

SIDS is associated with prenatal drug use: a meta-analysis and systematic review of 4 238 685 infants

OBJECTIVE

To conduct a meta-analysis to determine the association between prenatal drug exposure and risk of sudden infant death syndrome (SIDS).

DESIGN

Studies were searched using PubMed, Medline and Embase and restricted to English, with no publication date limit. Selected studies included published cohort, population or case studies comparing the incidence of SIDS among drug-exposed with drug-free controls. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-Analysis of Observational Studies in Epidemiology guidelines. Data were pooled using a random-effects model to evaluate risk ratios (RR).

SETTING

High-income countries.

PATIENTS

Children with a history of prenatal drug exposure.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

RR of SIDS between drug-exposed and control infants.

RESULTS

Sixteen studies (36 730 infants with any prenatal drug exposure, 21 661 exposed to opioids, 21 571 exposed to cocaine, 5031 exposed to methadone compared with 4 201 955 with no exposure). Any prenatal drug exposure was associated with an increased crude risk of SIDS (RR 7.84, 95% CI 5.21 to 11.81). Prenatal opioid exposure had the highest associative crude risk of SIDS (RR 9.76, 95% CI 5.28 to 18.05), followed by methadone (RR 9.52, 95% CI 4.60 to 19.70) and cocaine (RR 4.40, 95% CI 2.52 to 7.67). Increased crude risk persisted after adjusting for socioeconomic factors (RR 4.24, 95% CI 1.39 to 12.88). The incidence of SIDS for this cohort decreased between 1972 and 2020 but remained significantly higher than controls.

CONCLUSION

Exposure to any drug of dependency during pregnancy is associated with an increased risk of SIDS after controlling for socioeconomic factors. Further study to evaluate mechanisms and contribution of other confounders (eg, smoking) is warranted.

Fostering Hope: Comprehensive Accessible Mother-Infant Dyad Care for Neonatal Abstinence (CAIN)

Hospital and community healthcare providers have expressed concerns around the continuity and quality of care for infants with neonatal abstinence syndrome (NAS) during hospitalization and transition home. This qualitative study explored the experiences of hospital and community-based healthcare providers and identified themes related to the management of NAS for mothers and infants. Healthcare providers that cared for women with substance use disorders and/or cared for newborns with NAS in a large urban setting in Canada met inclusion criteria for this study and were interviewed in groups or as individuals. Interview transcripts were reviewed iteratively using inductive thematic analysis to identify an overarching theme linked with primary themes. In total, 45 healthcare providers were interviewed. Qualitative analysis of their experiences derived the overarching theme of hope with five primary themes being: mother/infant, mental health, system, judgement, and knowledge. The study identified gaps in NAS care including fear, stigma, and language. This research demonstrates that programs and interventions that work with mothers and newborns with NAS must foster hope in mothers, families, and in the extended care provider team and improve communication between hospital and community networks.

Prevalence of positive toxicology analysis from the French national registry for sudden unexpected infant death (Tox-MIN)

BACKGROUND

Sudden unexpected infant death (SUID) remains the leading cause of postnatal mortality in many countries. French and international guidelines recommend a thorough examination with toxicology studies.

OBJECTIVES

The main objective was to determine the prevalence of toxic detection and positive analyses. The secondary objectives were to describe the different toxics and compare children with positive (Tox+) and negative results (Tox-) with other SUID risk factors.

DESIGN AND METHODS

We used the data registered from May 2015 to December 2018 by the French national SUID registry (OMIN). It collects data for all SUID cases admitted to any of the 35 participating French SUID referral centers.

RESULTS

Of the 624 SUID cases registered in the OMIN, a post-mortem toxicological analysis was performed in 398 infants. Thirty-six patients (9%) were positives for expected (Etox+ (n = 19 [53%], e.g., resuscitation drugs, regular treatments) and unexpected (UTox+) (n = 17 [47%]) toxics. The unexpected toxics were opioids (n = 8), cannabis (n = 4), cocaine (n = 3), cotinine (n = 2), carbon monoxide (n = 2), caffeine (n = 2), alcohol (n = 1) and GHB (n = 1). UTox + infants had a different seasonal distribution (p = .03), a higher incidence of inappropriate sleeping position and bedding at the time of death (respectively OR 3.8, p = .037 - OR 5.4, p = .026); inadequate body hygiene (OR 10.6, p = .0005), a younger maternal age (p = .045) and a higher rate of maternal drug abuse (OR 21.9, p = .0008).

CONCLUSION

The high rate of positive results warrants routine toxicology testing. The imputability of identified molecules is complicated by the presence of other known risk factors for SUID.

Pharmacological and non-pharmacological treatments for the Neonatal Abstinence Syndrome (NAS)

Neonatal abstinence syndrome is defined by signs and symptoms of withdrawal that infants develop after intrauterine maternal drug exposure. All infants with documented in utero opioid exposure, or a high pre-test probability of exposure should have monitoring with a standard assessment instrument such as a Finnegan Score. A Finnegan score of >8 is suggestive of opioid exposure, even in the absence of declared use during pregnancy. At least half of infants in most locales can be treated without the use of pharmacologic means. For this reason, symptom scores will drive the decision for pharmacologic therapy. Nevertheless, all infants, regardless of initial manifestations, should be first be managed with non-pharmacologic approaches which in turn, should not be considered as the sole alternative to drug therapy, but rather, as the base upon which all patients are treated. Those who continue to have symptoms despite supportive care should be pharmacologically treated, which in the most severe cases, is life-saving.
