Association Between Clubfoot and Neonatal Abstinence Syndrome in the United States, 2018-2022.

The United States has seen an increase in opioid use and misuse over the last 2 decades. Infants have been impacted by the opioid epidemic, with a reported 5-fold increase in the incidence of neonatal abstinence syndrome (NAS) over the last 2 decades. There are many conditions associated with NAS, and thus, the current study sought to examine the association between NAS and clubfoot. The study was retrospective, utilizing patient data from the Pediatric Hospital Information System (PHIS) database. Neonates presenting to any PHIS hospital between 2018 and 2022 were identified and included in the study. Patients with NAS and clubfoot were identified utilizing the International Classification of Diseases (ICD)-9 and 10 codes. Univariable and multivariable analyses were performed to investigate associations between clubfoot, race, ethnicity, insurance type, gestational age, length of stay, NAS, and comorbidity burden. A total of 458,274 patients were identified, of whom 2337 (0.5%) had a clubfoot diagnosis and 5431 (1.2%) had a diagnosis of NAS. Multivariable logistic regression revealed higher independent odds of clubfoot among patients with a diagnosis of NAS [odds ratio (OR): 1.49], patients with a greater number of comorbidities (OR: 4.75 for 1 comorbidity vs. none, and 21.19 for 2+ comorbidities, vs. none), patients with a greater gestational age (OR: 1.01 per week increase), and those with an increased length of stay (OR: 1.00 per day increase). A lower independent odds of clubfoot was observed among patients of Asian race (OR: 0.66), Hispanic/Latino ethnicity (OR: 0.80), non-Hispanic Black (OR: 0.75), and multiracial (OR: 0.80) ethnicity/race relative to non-Hispanic/Latino White patients (P<0.05 for all). Patients with a diagnosis of NAS demonstrated higher odds of clubfoot, in addition to sociodemographic factors, as well as comorbidity burden.

Differences in withdrawal symptoms, microglia activity, and cognitive functioning in rats exposed to continuous low-dose heroin in-utero

IntroductionOpioid use during pregnancy and subsequent neonatal opioid withdrawal syndrome (NOWS) have been associated with poor developmental outcomes including cognitive functioning. Less is known about the underlying molecular effects of prenatal opioid exposure and subsequent withdrawal; however, given the recent increase in NOWS cases, there is a pressing need to better understand these effects, which may partially explain cognitive deficits that have been observed in both preclinical NOWS models and patients with NOWS. This study evaluated the effects of prenatal heroin exposure and subsequent precipitated withdrawal symptoms on microglial reactivity in the nucleus accumbens (NAc), dorsal hippocampus (HC), and ventral tegmental area (VTA) in rat neonates, as well as cognitive functioning at three developmental time points using the Morris Water Maze (MWM) task. MethodsHeroin or saline (2 mg/kg) was randomly assigned and administered to six pregnant Sprague Dawley rat dams via osmotic minipump. A total of 63 rat neonates underwent naloxone-precipitated (5 mg/kg, subcutaneous injection) withdrawal testing at postnatal day 10 (PN10). Following withdrawal testing, neonates were randomly assigned to undergo perfusion and subsequent immunohistochemistry experiments to fluoresce Iba-1 for microglia detection, or to undergo the MWM task at three separate developmental time points (PN21–23; PN37; PN60) for cognitive testing. ResultsResults suggest that in-utero heroin exposure led to an increase in ultrasonic vocalizations during naloxone-precipitated withdrawal; a sensitive index of withdrawal in rat neonates. Additional results suggest increased microglial reactivity in the HC and VTA, but not the NAc, as well as reduced performance during the MWM in the group exposed to heroin in-utero. DiscussionTogether, these data suggest that in-utero opioid exposure is associated with microglial reactivity in brain regions associated with learning and memory, and may be associated with later cognitive deficits. Further research is needed to characterize these findings, which may inform future therapeutic strategies for this vulnerable population.

A Population-Based Study on Women Who Used Alcohol during Pregnancy and Their Neonates in Ontario, Canada.

Data from birth registries can be studied to assess the prevalence of prenatal alcohol use and associated maternal and neonatal outcomes. Linked maternal and neonatal data (2015-2018) for alcohol-exposed pregnancies were obtained from the Better Outcomes Registry and Network (BORN) Ontario. Descriptive statistics were generated for maternal demographics, prenatal substance use, mental health/substance use history, and neonatal outcomes. Logistic regression models were performed to assess the odds of prenatal heavy (binge or weekly) alcohol and other substance use based on mental health/substance use history and other maternal demographics, and the impacts of heavy alcohol use and other prenatal substance exposures on neonatal outcomes. A total of 10,172 (2.4%) women reported alcohol use during pregnancy. One-third had pre-existing or current mental health and/or substance use problems, which was associated with significantly higher odds of heavy alcohol use during pregnancy. Prenatal exposure to heavy alcohol use was associated with increased odds of neonatal abstinence syndrome (2.5 times); respiratory distress syndrome (2.3 times); neonatal intensive care unit (NICU) admission (58%); and hyperbilirubinemia (57%). Prenatal exposure to one or more substances in addition to alcohol was associated with significantly higher odds of fetal/maternal/placental pregnancy complications; preterm birth; NICU admission; low APGAR scores; one or more confirmed congenital anomalies at birth; respiratory distress syndrome; and intrauterine growth restriction. It is crucial to routinely screen childbearing-age and pregnant women for alcohol and other substance use as well as mental health problems in order to prevent adverse maternal and neonatal outcomes.

Comparative Safety of In Utero Exposure to Buprenorphine Combined With Naloxone vs Buprenorphine Alone

Buprenorphine combined with naloxone is commonly used to treat opioid use disorders outside of pregnancy. In pregnancy, buprenorphine alone is generally recommended because of limited perinatal safety data on the combination product. To compare perinatal outcomes following prenatal exposure to buprenorphine with naloxone vs buprenorphine alone. Population-based cohort study using health care utilization data from Medicaid-insured beneficiaries in the US from 2000 to 2018. The cohort was restricted to pregnant individuals linked to their liveborn infants, with maternal Medicaid enrollment from 3 months before pregnancy to 1 month after delivery and infant enrollment for the first 3 months after birth, unless they died sooner. Use of buprenorphine with naloxone vs buprenorphine alone during the first trimester based on outpatient dispensings. Outcomes included major congenital malformations, low birth weight, neonatal abstinence syndrome, neonatal intensive care unit admission, preterm birth, respiratory symptoms, small for gestational age, cesarean delivery, and maternal morbidity. Confounder-adjusted risk ratios were calculated using propensity score overlap weights. This study identified 3369 pregnant individuals exposed to buprenorphine with naloxone during the first trimester (mean [SD] age, 28.8 [4.6] years) and 5326 exposed to buprenorphine alone or who switched from the combination to buprenorphine alone by the end of the first trimester (mean [SD] age, 28.3 [4.5] years). When comparing buprenorphine combined with naloxone with buprenorphine alone, a lower risk for neonatal abstinence syndrome (absolute risk, 37.4% vs 55.8%; weighted relative risk, 0.77 [95% CI, 0.70-0.84]) and a modestly lower risk for neonatal intensive care unit admission (absolute risk, 30.6% vs 34.9%; weighted relative risk, 0.91 [95% CI, 0.85-0.98]) and small for gestational age (absolute risk, 10.0% vs 12.4%; weighted relative risk, 0.86 [95% CI, 0.75-0.98]) was observed. For maternal morbidity, the comparative rates were 2.6% vs 2.9%, respectively, and the weighted relative risk was 0.90 (95% CI, 0.68-1.19). No differences were observed with respect to major congenital malformations overall, low birth weight, preterm birth, respiratory symptoms, or cesarean delivery. Results were consistent across sensitivity analyses. There were similar and, in some instances, more favorable neonatal and maternal outcomes for pregnancies exposed to buprenorphine combined with naloxone compared with buprenorphine alone. For the outcomes assessed, compared with buprenorphine alone, buprenorphine with naloxone during pregnancy appears to be a safe treatment option. This supports the view that both formulations are reasonable options for the treatment of opioid use disorder in pregnancy, affirming flexibility in collaborative treatment decision-making.

Infant Feeding and Weight Trajectories in the Eat, Sleep, Console Trial

Infants with neonatal opioid withdrawal syndrome (NOWS) cared for with the Eat, Sleep, Console (ESC) care approach receive less pharmacologic treatment and have shorter hospital stays compared to usual care with the Finnegan Neonatal Abstinence Scoring Tool, but the effects of these approaches on feeding and weight are unknown. To evaluate feeding practices and weight trajectories in infants cared for with ESC vs usual care. ESC-NOW is a cluster randomized trial of infants with NOWS born at 36 weeks' gestation or later at 26 US hospitals from September 2020 to March 2022. Each site transitioned from usual care to ESC (the study intervention) at a randomized time. Feeding was per site practice and not specified by the intervention. Feeding and weight outcomes were assessed at hospital discharge. ESC vs usual care. Outcomes include prospectively identified secondary end points related to feeding and weight. z Scores were used for growth to account for corrected gestational age at the time of measurement. All analyses were intention to treat and adjusted for study design. Maternal/infant characteristics were included in adjusted models. The analyses included 1305 infants (702 in usual care and 603 in ESC; mean [SD] gestational age, 38.6 [1.3] weeks; 655 [50.2%] male and 650 [49.8%] female). Baseline demographic characteristics were similar between groups. The proportion of breastfed infants was higher in the ESC group (52.7% vs 41.7%; absolute difference, 11%; 95% CI, 1.0-20.9). A higher proportion of infants cared for with ESC received exclusive breast milk (15.1% vs 6.7%; absolute difference, 8.4%; 95% CI, 0.9-5.8) or any breast milk (38.8% vs 27.4%; absolute difference, 11.4%; 95% CI, 0.2-23.1) and were directly breastfeeding at discharge (35.2% vs 19.5%; absolute difference, 15.7%; 95% CI, 4.1-27.3). There was no difference in proportion of infants with weight loss greater than 10% or maximum percentage weight loss, although infants cared for with ESC had a lower weight z score on day of life 3 (-1.08 vs -1.01; absolute difference, 0.07; 95% CI, 0.02-0.12). When pharmacologic treatment was added into the model, no breastfeeding outcomes were statistically significant. In this study, infants cared for with ESC were more likely to initiate and continue breastfeeding and had no difference in percentage weight loss. The improvement in breastfeeding with ESC may be driven by reduction in pharmacologic treatment and provision of effective nonpharmacologic care. ClinicalTrials.gov Identifier: NCT04057820.

Prescription Opioid Exposure During Pregnancy and Risk of Spontaneous Preterm Delivery

(Abstracted from JAMA Network Open 2024;7(2):e2355990 Up to 21% of pregnant people use opioids to treat acute pain at some point in their pregnancies. Several studies have examined the impact of medication-assisted therapy among women with opioid use disorders and their outcomes, including neonatal opioid withdrawal syndrome.

Sex-Related Differences in the Severity of Neonatal Opioid Withdrawal Syndrome: A Single-Center, Retrospective Cohort Study.

Factors associated with the development and expression of Neonatal Opioid Withdrawal Syndrome (NOWS) are poorly understood. There are conflicting data on the role of infant sex in NOWS. Some studies have suggested that infant sex predicts NOWS severity and adverse outcomes, with male infants being more vulnerable. This study aimed to analyze if infant sex is associated with the severity of NOWS among those who require pharmacologic treatment. This is a retrospective cohort study of term and late-preterm infants (≥35 weeks gestation) exposed to in utero opioids, born between September 2006 and August 2022, and required pharmacologic treatment for NOWS. Maternal and infant demographics were collected. Indicators of the severity of NOWS (duration of medical treatment (DOT), duration of hospitalization, maximum dose of opioid treatment, and use of secondary medications) were compared between male and female infants. Standard statistical tests and regression analysis were used to establish the differences in outcomes after accounting for confounders and baseline differences. Out of the 1,074 infants included in the study, 47.9% were female, and 52.1% were male. There was no significant difference in demographic and baseline clinical characteristics between groups except for anthropometry (birth weight, head circumference, and length) and Apgar score at 5 minutes. The median DOT (25 days [14, 39] vs. 23 days [13, 39], p = 0.57), length of hospital stay (31.5 days [20, 44] vs. 28 days [20, 44], p = 0.35), treatment with phenobarbital (24.7 vs. 26.3%, p = 0.56), and clonidine (3.9 vs. 3.8%, p = 0.9) were similar in both groups. The differences remained nonsignificant after adjusting for birth anthropometric measurements, gestational age, 5-minute Apgar score, small for gestational age status, and maternal exposure to benzodiazepines. In this cohort of neonates, sex-related differences were not identified to influence the severity of NOWS among those who required pharmacological treatment. · Vulnerability to NOWS is multifactorial.. · The role of infant sex in the severity of NOWS is not concrete.. · We noted that sex did not impact NOWS severity in those treated..

U.S. State rates of newborns reported to child protection at birth for prenatal substance exposure

BackgroundIn the U.S., the opioid epidemic has revitalized national attention to newborns with prenatal substance exposure (PSE). These newborns and their caregivers have specific health and treatment needs and frequently interact with multiple systems, including child protection systems (CPS). MethodsThis study calculated rates of newborns (less than 15 days old) reported to CPS per 1,000 births due to PSE by state and year using data from the National Child Abuse and Neglect Data System (NCANDS). Given the lack of a clear definition of PSE reports in the data, we calculated rates using three different definitions. To examine the relationship between different state laws regarding the mandated reporting of PSE and PSE reports rates, we used panel data analysis. ResultsRates of newborn reports more than doubled between 2011 and 2019. There was extensive state variability of rates including some states that were consistently more than 100 % greater than and others consistently more than 150 % less than the annual national mean. Reporting rates were not associated with state requirements to report PSE, but were positively associated with rates of diagnosed neonatal abstinence syndrome. ConclusionState-level inconsistencies in identification, reporting, and CPS responses prevent a clear understanding of the scope of the affected population and service needs.

Health Care Needs and Costs for Children Exposed to Prenatal Substance Use to Adulthood.

Children exposed to substance use during pregnancy have increased health needs but whether these are influenced by engagement in out-of-home care is uncertain. To evaluate the association between substance use during pregnancy, out-of-home care and hospitalization utilization, and costs from birth up to age 20 years. This was a retrospective cohort study using individual-linked population birth, hospital, and out-of-home care information of all liveborn infants from New South Wales, Australia, between 2001 and 2020 using longitudinal population-based linkage records from administrative databases. Substance use during pregnancy included newborns with neonatal abstinence syndrome (n = 5946) and intrauterine exposure to drugs of addiction (n = 1260) and other substances (eg, tobacco, alcohol, and illicit drugs or misused prescription drugs; n = 202 098). Children not exposed to substance use during pregnancy were those without known exposure to substance use during pregnancy (n = 1 611 351). Data were analyzed from July 2001 to December 2021. Main outcomes were hospital readmission, length of stay, and cost burden associated with substance use during pregnancy from birth up to age 20 years. Outcomes were investigated using 2-part and Poisson regression models adjusted for sociodemographic characteristics. Mediation analysis was used to evaluate whether the association of substance use during pregnancy with risk of readmission was mediated through engagement with out-of-home care. Of the 1 820 655 live births, 935 807 (51.4%) were male. The mean (SD) age of mothers was 30.8 (5.5) years. Compared with children who were not exposed to substance use during pregnancy, those who were exposed incurred significantly higher birth hospital costs (adjusted mean difference, A$1585 per child [US$1 = A$1.51]; 95% CI, 1585-1586). If discharged alive, more children with exposure to substance use during pregnancy had at least 1 readmission (90 433/209 304 [43.4%] vs 616 425/1 611 351[38.3%]; adjusted relative risk [RR], 1.06; 95% CI, 1.06-1.07), most commonly for respiratory conditions (RR, 1.11; 95% CI, 1.09-1.12) and mental health/behavioral disorders (RR, 1.36; 95% CI, 1.33-1.41). Excess hospital costs associated with substance use during pregnancy were A$129.0 million in 2019 to 2020. Mediation analyses showed that any out-of-home care contact mediated the association between substance use during pregnancy and risk of inpatient readmission and lower health care cost (decreased by A$25.4 million). For children with neonatal abstinence syndrome, any out-of-home care contact mediated readmission risk by approximately 30%, from adjusted RR, 1.28; 95% CI, 1.19-1.35, to RR, 1.01; 95% CI, 0.98-1.02. Children who were exposed to substance use during pregnancy incurred more hospital costs than children who were not exposed up to 20 years of age, but this was reduced in association with any contact with out-of-home care. This provides insights into possible strategies for reducing health and financial burdens associated with exposure to substance use during pregnancy for children.

Increased risk of severe neonatal opioid withdrawal syndrome in pregnancies with low placental ABCB1 DNA methylation.

Neonatal opioid withdrawal syndrome (NOWS) is unpredictable. We assessed relationships between placental DNA methylation with in-utero opioid exposure and NOWS severity. Secondary analysis of a prospective multicenter cohort study of pregnancies on methadone or buprenorphine, ≥34 weeks, singleton, 18 or greater. Placental biopsies were collected. Placental DNA methylation levels of ABCG1, ABCG2, CYP19A1, and HSD11B2 were quantified via pyrosequencing following bisulfite conversion. CYP19A1 mRNA levels and umbilical cord drug levels were determined by RT-qPCR and LC-MS respectively. Severe NOWS was diagnosed through Finnegan scoring. P value < 0.05 was significant. Thirty-eight dyads were included. Promoter region methylation for placental ABCB1 was lower in severe NOWS compared to non-severe NOWS (p = 0.04). Placental CYP19A1 methylation was inversely related to CYP19A1 mRNA levels and associated with umbilical cord norbuprenorphine levels (p < 0.01), but not umbilical cord methadone levels. Lower placental ABCB1 methylation was associated with severe NOWS. Higher placental CYP19A1 methylation correlated with higher umbilical cord norbuprenorphine levels.

Neonatal abstinence syndrome and infant mortality and morbidity: a population-based study.

Infant health among newborns with neonatal abstinence syndrome (NAS) has been understudied. We examined infant mortality and hospitalizations among infants diagnosed with NAS after birth. All live births in British Columbia (BC), Canada, for fiscal years from 2004-2005 to 2019-2020, were included (N = 696,900). NAS was identified based on International Classification of Diseases, version 10, Canadian modification (ICD-10-CA) codes; the outcomes included infant death and hospitalizations during the first year of life, ascertained from BC linked administrative data. Generalized estimating equation models were used to adjust for maternal factors. There were 2,439 infants with NAS (3.50 per 1,000 live births). Unadjusted for other factors, infant mortality was 2.5-fold higher in infants with vs. without NAS (7.79 vs. 3.08 per 1,000 live births, respectively) due to increased post-discharge mortality NAS (5.76 vs. 1.34 per 1,000 surviving infants, respectively). These differences diminished after adjustment: adjusted odds ratio (AOR) for infant death was 0.85 [95% confidence interval (CI): 0.52-1.39]; AOR for post-discharge death was 1.75 (95% CI 1.00-3.06). Overall, 22.3% infants with NAS had at least one hospitalization after post-neonatal discharge, this proportion was 10.7% in those without NAS. During the study period, discharge to foster care declined from 49.5% to 20.3% in infants with NAS. Unadjusted for other factors, infants with NAS had increased post-discharge infant mortality and hospitalizations during the first year of life. This association diminished after adjustment for adverse maternal and socio-medical conditions. Infants with NAS had a disproportionately higher rate of placement in foster care after birth, although this proportion declined dramatically between 2004/2005 and 2019/2020. These results highlight the importance of implementing integrated care services to support infants born with NAS and their mothers during the first year of life and beyond, even though NAS itself is not independently associated with increased infant mortality.

Buprenorphine vs. morphine: impact on neonatal opioid withdrawal syndrome (NOWS) outcomes in a single center retrospective study.

To compare clinical outcomes for infants with neonatal opioid withdrawal syndrome (NOWS) treated with buprenorphine or morphine. Retrospective study of infants born ≥35 weeks' gestation and admitted to the NICU for NOWS treatment between 2011 and 2022. Length of treatment, length of stay in the hospital, and the need for secondary medications were compared between buprenorphine and morphine treated neonates. Multiple regression analysis was performed, adjusting for baseline differences and confounders. 417 neonates were treated with morphine and 232 with buprenorphine. The buprenorphine group had shorter treatment days [-10.8 days; 95% CI: -8.08 to -13.53] and shorter hospital stay [-11.8 days; 95% CI: -8.83 to -14.78]. The buprenorphine group was no more likely to receive phenobarbital or clonidine (26% vs. 29%). In this large single-center study, buprenorphine was associated with shorter lengths of treatment and hospital stay in the treatment of NOWS compared to morphine.

Sleep and circadian rhythm activity alterations during adolescence in a mouse model of neonatal fentanyl withdrawal syndrome.

Fentanyl, a highly potent synthetic opioid, is a major contributor to the ongoing opioid epidemic. During adulthood, fentanyl is known to induce pronounced sleep and circadian disturbances during use and withdrawal. Children exposed to opioids in utero are likely to develop neonatal opioid withdrawal syndrome, and display sleep disturbances after birth. However, it is currently unknown how neonatal opioid withdrawal from fentanyl impacts sleep and circadian rhythms in mice later in life. To model neonatal opioid withdrawal syndrome, mice were treated with fentanyl from postnatal days 1 through 14, analogous to the third trimester of human gestation. After weaning, fentanyl and saline treated mice underwent non-invasive sleep and circadian rhythm monitoring during adolescence postnatal days 23 through 30. Neonatal fentanyl exposure led to reduced duration of wake and a decrease in the number of bouts of non-rapid eye movement sleep. Further, neonatally exposed mice displayed an increase in the average duration of rapid eye movement sleep bouts, reflecting an overall increase in the percent time spent in rapid eye movement sleep across days. Neonatal fentanyl exposure leads to altered sleep-wake states during adolescence in mice.

School performance in children with prenatal drug exposure and out-of-home care in NSW, Australia: a retrospective population-based cohort study.

Prenatal drug exposure (PDE) is a global public health problem that is strongly associated with the need for child protection services, including placement into out-of-home care (OOHC). We aimed to assess school outcomes for children with PDE (both with and without neonatal abstinence syndrome [NAS]) and the association of school performance with OOHC. Using linked population health, OOHC, and school test data, we compared results on the Australian standardised curriculum-based test, the National Assessment Program-Literacy and Numeracy (NAPLAN), for children with PDE who were born in New South Wales (NSW) between 2001 and 2020 and had completed at least one NAPLAN test between Jan 1, 2008, and June 30, 2021, administered in Year 3 (age 8-9 years), Year 5 (age 10-11 years), Year 7 (age 12-13 years), or Year 9 (age 14-15 years). Linked datasets included NSW Perinatal Data Collection (birth data), NSW Admitted Patient Data Collection (hospital diagnoses), NSW Education Standards Authority (NAPLAN scores), NSW Family and Community Services Dataset-KiDS Data Collection (OOHC information), NSW Mental Health Ambulatory Data Collection, and NSW Registry for Births, Deaths, and Marriages. The primary outcome was scoring above or below the National Minimum Standard (NMS) in any test domain (mathematics, language, writing, and spelling) at each year level, comparing the relative risk of scoring below NMS between children with and without PDE (and with or without NAS within the PDE group), and with and without OOHC contact. The association between OOHC on the likelihood of scoring above NMS was also investigated for PDE and non-PDE cohorts. The PDE cohort included 3836 children, and the non-PDE cohort included 897 487 children. Within the PDE cohort, 3192 children had a NAS diagnosis and 644 children had no NAS diagnosis. 1755 (45·8%) children with PDE required OOHC compared with 12 880 (1·4%) of 897 487 children without PDE. Children with PDE were more likely than children without PDE to score below NMS in any domain from Year 3 (risk ratio 2·72 [95% CI 2·58-2·76]) to Year 9 (2·36 [2·22-2·50]). Performance was similar regardless of a NAS diagnosis (Year 3: 0·96 [0·84-1·10]; Year 9: 0·98 [0·84-1·15]). The likelihood of scoring above NMS in Year 9 was reduced for children with PDE and without NAS (0·57 [0·45-0·73]) and NAS (0·58 [0·52-0·64]) compared with those without PDE, and also for children who received OOHC (0·60 [0·57-0·64]) compared with those without OOHC, when adjusted for confounders. Among children with PDE, those receiving OOHC had a similar likelihood of scoring above NMS compared with children who did not receive OOHC, from Year 3 (1·01 [0·92-1·11]) to Year 9 (0·90 [0·73-1·10]), when adjusted for confounding factors. By contrast, among children without PDE, those receiving OOHC were less likely to score above NMS than those who did not receive OOHC, from Year 3 (0·78 [0·76-0·80]) to Year 9 (0·58 [0·54-0·61]). Compared with children without PDE, school performance in children with PDE-regardless of whether they were diagnosed with NAS-is poor, and the gap widens with age. The risk of poor performance persists regardless of OOHC status. This finding underscores the need for all children with PDE to receive long-term, culturally sensitive, and proactive support to improve life success.

Implementing the eat, sleep, console method into a tertiary care delivery center

BackgroundInfants experiencing Neonatal Opioid Withdrawal Syndrome (NOWS) after birth has been a significant public health issue since the opioid crisis began in the U.S. Traditional assessment tools for symptom management have historically resulted in prolonged hospitalization and continued exposure to opioids after birth to treat them. PurposeEat, Sleep, Console (ESC) was implemented to replace a popular NOWS assessment tool in a neonatal intensive care unit at a large urban children's hospital's maternity center. The aim was to determine whether using ESC would decrease length of hospitalization, use of morphine for treatment, as well as increase the number of direct discharges from the postpartum unit. ResultsALOS decreased from 9.2 days to 6.2 days, a 33% reduction. Morphine treatment initiation decreased from 21.7% to 3.8%, an 82.4% reduction. Neither group included infants treated with a second line medication. Finally, the discharge rate improved by 47% directly from the postpartum unit. ConclusionsUsing ESC, all identified outcomes regarding management of infants with NOWS improved. Wide-scale use of ESC could have multiple benefits for this patient population including a reduction in healthcare costs and prolonged exposure to opioids after birth, as well as preservation of the mother-infant dyad in the immediate postpartum period. Further research is needed to study the long-term impact of the ESC method.

Opioid Medical Detoxification Compared to Opioid Agonist Treatment during Pregnancy: A Scoping Review.

Opioid use disorder (OUD) is highly prevalent, affecting up to 1% of pregnancies. The current standard of care for the management of OUD during pregnancy has been maintained with opioid agonist treatment (OAT), using either methadone or buprenorphine. OAT use has been associated with a risk of neonatal abstinence syndrome (NAS), which requires a longer neonatal length of stay for monitoring and possible pharmacological treatment. As a result, opioid medical detoxification (OMD) was proposed as an alternative strategy to reduce the stigma associated with OAT and to eliminate the risk of NAS by detoxifying or tapering pregnant persons during their pregnancy before delivery; however, the safety and effectiveness of OMD during pregnancy have not been established. This scoping review aims to summarize recent evidence related to maternal, obstetrical, and neonatal outcomes of OMD in comparison to OAT maintenance. This review also provides recommendations for future research initiatives to fill gaps in managing this patient population.

State-level factors associated with implementation of prescription drug monitoring program integration and mandatory use policies, United States, 2009-2020.

Prescription drug monitoring programs (PDMPs) have been widely adopted as a tool to address the prescription opioid epidemic in the United States. PDMP integration and mandatory use policies are 2 approaches states have implemented to increase use of PDMPs by prescribers. While the effectiveness of these approaches is mixed, it is unclear what factors motivated states to implement them. This study examines whether opioid dispensing, adverse health outcomes, or other non-health-related factors motivated implementation of these PDMP approaches. Time-to-event analysis was performed using lagged state-year covariates to reflect values from the year prior. Extended Cox regression estimated the association of states' rates of opioid dispensing, prescription opioid overdose deaths, and neonatal opioid withdrawal syndrome with implementation of PDMP integration and mandatory use policies from 2009 to 2020, controlling for demographic and economic factors, state government and political factors, and prior opioid policies. In our main model, prior opioid dispensing (HR 2.31, 95% CI 1.17, 4.57), neonatal opioid withdrawal syndrome hospitalizations (HR 1.55, 95% CI 1.09, 2.19), and number of prior opioid policies (HR 2.13, 95% CI 1.13, 4.00) were associated with mandatory use policies. Prior prescription opioid overdose deaths (HR 1.21, 95% CI 1.08, 1.35) were also associated with mandatory use policies in a model that did not include opioid dispensing or neonatal opioid withdrawal syndrome. No study variables were associated with implementation of PDMP integration. Understanding state-level factors associated with implementing PDMP approaches can provide insights into factors that motivate the adoption of future public health interventions.

Neonatal Opioid Withdrawal Syndrome Treatment Guidelines and Birth Hospital Utilization.

In November 2020, the American Academy of Pediatrics published guidelines for management of neonatal opioid withdrawal syndrome (NOWS), recommending nonpharmacologic treatment as the first-line approach, unless pharmacologic treatment is needed for severe NOWS. Using data from tertiary care pediatric hospitals, we examined the impact of the guidelines on use of pharmacotherapy, length of stay, and NICU admission for infants with NOWS. We extracted birth hospitalization data for newborns diagnosed with NOWS discharged from 2019 to 2022 from the Pediatric Health Information System. We compared hospital utilization and pharmacologic treatment pre- and postguidelines and used interrupted time series regression to examine trends over time. We included N = 824 newborns (n = 434 pre, n = 390 post) with NOWS from 11 hospitals. The use of pharmacologic treatment was significantly lower in the postguidelines period (59.0% pre versus 50.3% post; P = .01). Median length of stay was similar pre and post (P = .55). NICU admission was significantly lower in the postguidelines period (78.6% pre versus 46.7% post; P < .001), with an immediate decrease (β = -23.0%; P < .001) and a decrease over time in the postguidelines period (β = -0.7% per month; P = .03). Most hospitals reduced pharmacologic treatment (8 of 11; 73%) and NICU use (10 of 11; 91%) postguidelines. There was a reduction in the use of pharmacologic treatment and NICU utilization for infants with NOWS after the release of American Academy of Pediatrics guidelines for NOWS management.
