Neonatal Abstinence Syndrome and Maternal Opioid-Related Diagnoses in the US, 2010-2017

Prenatal opioid administration induces shared alterations to the maternal and offspring gut microbiome: A preliminary analysis

Background While many studies have described the impact of prenatal opioid exposure on development, possible mechanisms for how opioids exert developmental impairments remain elusive. Emerging evidence indicates disruptions in the maternal gut microbiome can alter offspring development; however, no studies to date have examined the impact of maternal opioid treatment on maternal-offspring microbiome dysbiosis. Methods A mouse model of prenatal methadone exposure (PME) was employed to assess the impact of maternal opioid treatment on the microbiome of methadone-treated dams (MD) and their offspring. Fecal samples were collected from dams (n = 8 per treatment), one male and one female offspring per dam (n = 8 offspring per sex per treatment) for 16S rRNA sequencing. Results Methadone treatment significantly increased the microbial diversity and led to an expansion in family level bacterial abundance. Correlational analysis revealed significant positive associations between dam and offspring measures of diversity indicating methadone-induced shifts in the microbial communities are shared between dam and offspring. Sixteen features in dams and 10 features in offspring were significantly differentially abundant between treatment groups with many features corresponding to the Lachnospiraceae NK4A136 genus. Of the six features identified as differentially abundant in both MD and PME offspring, all were assigned to the Lachnospiraceae NK4A136 group, and the abundances demonstrated strong positive correlations between dam and offspring. Conclusions These preliminary findings indicate that maternal opioid treatment during pregnancy alters the composition of the maternal microbiome, and this opioid-induced shift is similarly observed in offspring which could contribute to the impaired developmental phenotypes previously described.

Nurses' Descriptions of Interactions When Caring for Women With Perinatal Substance Use Disorders and Their Infants

The purpose of this review is to describe health care interactions between nurses and women with perinatal substance use disorders, including interactions with their infants from the perspective of the nurses. Findings from 11 qualitative inclusion articles were synthesized using a metasummary approach. The majority of articles showed that nurses experience problematic interactions when providing care to women with perinatal substance use disorders and their infants, although some results indicated that some nurses engage in interactions that are assuring. Six types of conflictual interactions were identified: inadequate care, distressing, condemning, deficient knowledge, rejecting, and dissatisfying. Two types of therapeutic interactions were identified: compassionate and supportive. The findings underscore the importance of managing stigma, enhancing knowledge of the science of addiction processes, and promoting best practices when caring for this population.

Perinatal insurance coverage and behavioural health-related maternal mortality

Increases in postpartum maternal deaths, including a substantial number associated with behavioural health conditions, are a public health crisis and have contributed to overall increases in maternal mortality. A leading hypothesis to explain this pattern suggests lack of availability or continuity of resources for behavioural health treatment after delivery, often secondary to lapses in insurance coverage. Extending postpartum Medicaid coverage through the first year postpartum could mitigate excess morbidity and mortality among postpartum individuals, particularly those with behavioural health conditions.

Predictors of Length of Stay and Cost of Hospitalization of Neonatal Abstinence Syndrome in the United States

Background

The incidence rate and economic burden of neonatal abstinence syndrome (NAS) are increasing in the United States (US). We explored the link between the length of stay (LOS) and hospitalization cost for neonatal abstinence syndrome in 2018.

Methods

This was a cross-sectional analysis of the 2018 national inpatient sample database. Newborn hospitalizations with neonatal abstinence syndrome and their accompanying comorbid conditions were identified using the International Classification of Diseases, 10th Edition diagnostic codes. Logistic regression was used to determine the impact of length of stay and the co-morbidities on inflation-adjusted hospital costs.

Results

The incidence of neonatal abstinence syndrome was 7.1 per 1000 births (95% CI 6.8-7.3) in 2018. The majority had Medicaid (84.1%), with a neonatal abstinence syndrome incidence of 13.2 (95% CI: 12.8-13.6). In adjusted analysis, every one-day increase in length of stay increased the hospital cost by $1,685 (95% CI: 1,639-1,731). Neonatal abstinence syndrome hospitalizations with Medicaid had a longer length of stay by 1.8 days (95% CI: 0.5-3.1). Co-morbidities further increased the length of stay: seizures: 13.8 days; sepsis: 4.1 days; respiratory complications: 4.4 days; and feeding problems: 5.8 days. Those at urban teaching hospitals had a longer length of stay by 7.3 days (95% CI: 5.8-8.8). Co-morbidities increased hospital cost as follows: seizures: $71,380; sepsis: $12,837; respiratory complications: $8,268; feeding problems: $7,737. The cost of hospitalization at large bed-size hospitals and urban teaching was higher by $5,243 and $12,005, respectively.

Conclusion

The incidence rate of neonatal abstinence syndrome remained high and was resource-intensive in 2018. Co-morbid conditions and hospitalization at urban teaching hospitals were major contributors to increased length of stay and hospital costs.

Implementing Trauma-Informed Strategies for Mothers of Infants with Neonatal Abstinence Syndrome

PURPOSE

To improve outcomes of infants with neonatal abstinence syndrome (NAS) by implementing an evidence-based approach to care.

METHODS

An interdisciplinary team developed and implemented an educational module about the elements and principles of trauma-informed care (TIC) and standardized education on NAS for mothers with substance use disorder (SUD). The team collaborated with community behavioral health professionals to secure the services of a certified recovery specialist. Primary outcome measures of average length of stay (LOS) and admissions to special care nursery (SCN) for NAS infants were analyzed.

RESULTS

Following health care team education on TIC and implementation of the standardized NAS brochure, average LOS decreased significantly from 6.5 to 5.1 days from baseline period (January-December 2019) to the implementation period (February-June 2020; p = 0.03). There was no difference in SCN admission from the baseline period (February-June 2019) to the implementation period (February-June 2020). Referrals to certified recovery specialists did not change.

CLINICAL IMPLICATIONS

Education on the impact of trauma on new mothers with SUD can promote collaboration between them and the neonatal team. Standardizing education for new mothers of infants with NAS can help to engage families of infants with NAS and improve clinical outcomes.
