RESUMO
OBJECTIVE: To investigate among US infants born at <37 weeks gestation (a) racial and ethnic disparities in sudden unexpected infant death (SUID) and (b) state variation in SUID rates and non-Hispanic Black (NHB)-non-Hispanic White (NHW) SUID disparity ratio. METHODS: In this retrospective cohort analysis of linked birth and death certificates from 50 states from 2005 to 2014, SUID was defined by the following International Classification of Diseases, 9th or 10th edition, codes listed on death certificates: (7980, R95 or Recode 135; ASSB: E913, W75 or Recode 146; Unknown: 7999 R99 or Recode 134). Multivariable models were used to assess the independent association between maternal race and ethnicity and SUID, adjusting for several maternal and infant characteristics. The NHB-NHW SUID disparity ratios were calculated for each state. RESULTS: Among 4â086â504 preterm infants born during the study period, 8096 infants (0.2% or 2.0 per 1000 live births) experienced SUID. State variation in SUID ranged from the lowest rate of 0.82 per 1000 live births in Vermont to the highest rate of 3.87 per 1000 live births in Mississippi. Unadjusted SUID rates across racial and ethnic groups varied from 0.69 (Asian/Pacific Islander) to 3.51 (NHB) per 1000 live births. In the adjusted analysis, compared with NHW infants, NHB and Alaska Native/American Indian preterm infants had greater odds of SUID (aOR, 1.5;[95% CI, 1.42-1.59] and aOR, 1.44 [95% CI, 1.21-1.72]) with varying magnitude of SUID rates and NHB-NHW disparities across states. CONCLUSIONS: Significant racial and ethnic disparities in SUID among preterm infants exist with variation across US states. Additional research to identify the drivers of these disparities within and across states is needed.

OBJECTIVE: Delivery of very preterm and very low birth weight neonates (VPT/VLBW) in a nonlevel III neonatal intensive care unit (NICU) increases risk of morbidity and mortality. Study objectives included the following: (1) Determine incidence of VPT/VLBW delivery (<32 weeks gestational age and/or birth weight <1,500 g), in nonlevel III units in Colorado; (2) Evaluate the independent association between residence and nonlevel III unit delivery; (3) Determine the incidence of and factors associated with postnatal transfer. STUDY DESIGN: This retrospective cohort study used 2007 to 2016 Colorado birth certificate data. Demographic and clinical characteristics by VPT/VLBW delivery in level III NICUs versus nonlevel III units were compared using Chi-square analyses. Multivariable logistic regression was used to estimate the independent association between residence and VPT/VLBW delivery. RESULTS: Among patients, 897 of 10,015 (8.96%) VPT/VLBW births occurred in nonlevel III units. Compared with infants born to pregnant persons in urban counties, infants born to those residing in rural (adjusted odds ratio [AOR] = 1.58, 95% confidence interval [CI]: 1.33, 1.88) or frontier (AOR = 3.19, 95% CI: 2.14, 4.75) counties were more likely to deliver in nonlevel III units and to experience postnatal transfer within 24 hours (rural AOR = 2.24, 95% CI: 1.60, 3.15; frontier AOR = 3.91, 95% CI: 1.76, 8.67). Compared with non-Hispanic Whites, Hispanics were more likely to deliver VPT/VLBW infants in nonlevel III units (AOR = 1.36, 95% CI: 1.15, 1.61). CONCLUSION: A significant number of VPT/VLBW neonates were born in nonlevel III units with associated disparities by race/ethnicity and nonurban residence. KEY POINTS: · Preterm delivery in a nonlevel III NICU increases risk of neonatal morbidity and mortality.. · A significant number of preterm deliveries in Colorado occur in hospitals with nonlevel III NICUs.. · Disparities in preterm delivery by race/ethnicity and nonurban residence exist..

OBJECTIVE: As pediatric COVID-19 vaccine eligibility expands, understanding predictors of vaccine intent is critical to effectively address parental concerns. Objectives included: (1) Evaluate maternal COVID-19 vaccine intent for child(ren) and associated predictors of stated intent; (2) Describe attitudes related to hypothetical vaccination policies; (3) Summarize themes associated with intention to vaccinate child(ren) for COVID-19. STUDY DESIGN: Mothers enrolled in Heath eMoms, a longitudinal survey project, were recruited for this electronic COVID-19 survey. Chi-square analysis was used to compare proportions of respondent characteristics based on vaccination intent. Population survey logistic regression was used for multivariable modeling to assess the independent association between vaccine intent and demographics. RESULTS: The response rate was 65.3% (n = 1884); 44.2% would choose vaccination, 20.3% would not choose vaccination, and 35.5% are unsure whether to have their child(ren) vaccinated for COVID-19. Black mothers (AOR 0.26, 95% CI 0.13, 0.54), respondents with less than high school education (AOR 0.26, 95% 0.12, 0.56) and those in rural areas (AOR 0.28, 95% CI 0.16, 0.48) were less likely to choose vaccination. Commonly cited reasons for vaccine hesitancy include the belief that the vaccine was not tested enough, is not safe, and there are concerns regarding its side effects. CONCLUSION: Over 50% of respondents do not intend or are unsure about their intent to vaccinate their child(ren) for COVID-19 with variability noted by demographics. Opportunities exist for perinatal and pediatric providers to educate pregnant people, parents, and caregivers with a focus on addressing concerns regarding vaccine safety and efficacy. KEY POINTS: · COVID-19 vaccination rates remain suboptimal, especially in the pediatric population, with variation across states.. · We found that the prevalence of vaccine acceptance for young children is low.. · We highlight opportunities for providers to educate parents, focusing on addressing vaccine safety and efficacy..

OBJECTIVE: The study aimed to better understand the perceptions of mothers of preterm infants regarding smoking behaviors and environmental tobacco smoke (ETS) exposure using qualitative methodology. STUDY DESIGN: Using a Grounded Theory approach, we conducted in-depth, semi-structured interviews with mothers of preterm infants, both smokers and nonsmokers. Using the Theory of Planned Behavior (TPB) as a conceptual framework for our questions, we conducted and analyzed interviews until theoretical saturation was reached. Analysis included an iterative coding process resulting in theme development. RESULTS: Our key themes aligned with the TPB domains of attitudes, perceived control, and social norms. Regarding attitudes, mothers expressed that smoking was bad for their infants and that preterm infants were more vulnerable than term infants. Regarding perceived control, mothers commented on their perceived ability to avoid ETS exposure with subthemes including strategies utilized to mitigate ETS exposure risk. Some mothers expressed difficulty avoiding ETS exposure, for example, when residing in high-density housing. Regarding perceived social norms, mothers whose family and friends were nonsmokers expressed ease avoiding ETS, while mothers whose family and friends were smokers expressed more difficulty avoiding ETS. CONCLUSION: Mothers used a variety of behaviors within the domains of the TPB to reduce ETS exposures in their preterm infants which can inform future neonatal intensive care unit-based interventional strategies. KEY POINTS: · Mothers felt ETS is harmful for preterm infants.. · Mothers reported strategies for ETS avoidance.. · Mothers reported barriers to ETS avoidance.. · TPB can frame mothers' ETS-related behaviors..

OBJECTIVE: Investigate whether safe infant sleep prioritization by states through the Title V Maternal and Child Block Grant in 2010 differentially impacted maternal report of supine sleep positioning (SSP) for Non-Hispanic White (NHW) and Non-Hispanic Black (NHB) U.S.-born infants. STUDY DESIGN: We analyzed retrospective cross-sectional data from the Pregnancy Risk Assessment Monitoring System (PRAMS) from 2005 to 2015 from 4 states: WV and OK (Intervention) and AR and UT (Control). PRAMS is a population-based surveillance system of maternal perinatal experiences which is linked to infant birth certificates. Piece-wise survey linear regression models were used to estimate the difference in the change in slopes of SSP percents in the pre- (2005-2009) and post- (2011-2015) periods, controlling for maternal and infant characteristics. Models were also stratified by race/ethnicity. RESULTS: From 2005 to 2015, for NHW infants, SSP improved from 61.5% and 70.2% to 82.8% and 82.3% for intervention and control states, respectively. For NHB infants, SSP improved from 30.6% and 26.5% to 64.5% and 53.1% for intervention and control states, respectively. After adjustment for maternal characteristics, there was no difference in the rate of SSP change from the pre- to post- intervention periods for either NHW or NHB infants in intervention or control groups. CONCLUSION: Compared with control states that did not prioritize safe infant sleep in their 2010 Title V Block Grant needs assessment, intervention states experienced no difference in SSP improvement rates for NHW and NHB infants. While SSP increased for all infants during the study period, there was no causal relationship between states' prioritization of safe infant sleep and SSP improvement. More targeted approaches may be needed to reduce the racial/ethnic disparity in SSP and reduce the risk for sleep-associated infant death. KEY POINTS: · Supine sleep positioning improved for Black and White infants in the U.S.. · State prioritization of safe infant sleep did not directly impact SSP for NHB or NHW infants.. · More targeted approaches may be needed to reduce racial/ethnic disparities in safe sleep practices.

BACKGROUND: Sleep-associated infant death is the leading cause of postneonatal mortality in the United States. Preterm infants are at higher risk for sleep-associated death, but maternal adherence to safe sleep practices is lower than for mothers of full-term infants. Data are lacking on whether maternal neonatal intensive care unit (NICU) visitation time impacts safe sleep compliance after hospital discharge. PURPOSE: For mothers of preterm infants, to investigate the association of time days per week spent in the NICU and adherence to safe sleep practices after discharge. METHODS: A prospective observational study of 109 mothers with infants born at less than 32 weeks from 4 Colorado NICUs who completed a survey at 6 weeks after discharge about infant sleep practices. Maternal time spent in the NICU was defined as the average number of days spent in the NICU per week of infant hospitalization, as documented in the electronic medical record. Multivariable logistic regression models assessed the relationship between time in the NICU and safe sleep adherence. Covariates included maternal/infant characteristics significant at P < .2 level in bivariate analysis. RESULTS: Predictors of compliance with all safe infant sleep practices included public/no insurance compared with private insurance (adjusted odds ratio [AOR] 0.29; 95% confidence interval [CI] 0.09-0.96), some college/associate-level education versus bachelor's degree (AOR 5.88; 95% CI 1.21-28.67), and depression/anxiety symptoms (AOR 0.37; 95% CI 0.14-0.97). NICU visitation days was not associated with adherence to safe sleep practices. IMPLICATIONS FOR PRACTICE AND RESEARCH: Maternal visitation days was not associated with adherence to safe infant sleep practices after discharge, highlighting the need to identify barriers and facilitators to engaging families about SUID risk-reducing behaviors.

In this retrospective cohort analysis of Colorado birth certificate records from April to December 2015-2020, we demonstrate that Colorado birthing individuals experienced lower adjusted odds of preterm birth after issuance of coronavirus-19 "stay-at-home" orders. However, this positive birth outcome was experienced only by non-Hispanic white and Hispanic mothers.

BACKGROUND: Mothers' engagement with their hospitalized preterm infant(s) is recognized as an important aspect of treatment in neonatal intensive care units (NICUs). However, no gold standard exists for measuring maternal engagement, and the various methods used to measure mothers' time have documented limitations. OBJECTIVES: This study sought to compare three measurement methods of maternal engagement (a five-item maternal cross-sectional survey, time use diaries, and electronic health records [EHRs]) to identify whether these methods capture consistent data and patterns in detected differences in measures of engagement. METHODS: Maternal engagement was defined as time spent visiting the infant in the NICU (presence), holding (blanket holding in the mother's arms or by kangaroo care [KC]), and caregiving (e.g., bathing and changing diapers). The survey estimating daily maternal engagement was administered in two Level III NICUs and one Level IV NICU at study enrollment, at least 2 weeks after admission. Mothers then completed the daily time use diaries until infant discharge. Data were also collected from participants' EHRs, charted by nursing staff. Wilcoxon signed-rank tests were used for pairwise analysis of the three measures for maternal engagement activities. RESULTS: A total of 146 participants had data across all three measurement types and were included in the analysis. In the Level III NICUs (n = 101), EHR data showed significantly more time spent with all engagement activities than the diary data. In the Level IV data, only differences in time holding were significant when comparing EHR data with survey data, with mothers reporting more time doing KC and less time blanket holding. Comparison of EHR data with diary data showed more time in all activities except KC. DISCUSSION: In most cases, time spent in engagement activities measured in the EHR was higher than in the surveys or time use diaries. Accuracy of measurements could not be determined because of limitations in data collection, and there is no gold standard for comparison. Nevertheless, findings contribute to ongoing efforts to develop the most valuable and accurate strategies for measuring maternal engagement-a significant predictor of maternal and infant health.

PURPOSE: To investigate assisted reproductive technology (ART) outcomes among adolescent and young-adult female cancer survivors. METHODS: The Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) data were linked to the Massachusetts Cancer Registry for 90,928 ART cycles in Massachusetts to women ≥ 18 years old from 2004 to 2013. To estimate relative risks (RR) and 95% confidence intervals (CI), we used generalized estimating equations with a log link that accounted for multiple cycles per woman and a priori adjusted for maternal age and cycle year. The main outcomes of interest were ART treatment patterns; number of autologous oocytes retrieved, fertilized, and transferred; and rates of implantation, clinical intrauterine gestation (CIG), live birth, and pregnancy loss. RESULTS: We saw no difference in number of oocytes retrieved (aRR: 0.95 (0.89-1.02)) or proportion of autologous oocytes fertilized (aRR: 0.99 (0.95-1.03)) between autologous cycles with and without a history of cancer; however, cancer survivors required a higher total FSH administered (aRR: 1.12 (1.06-1.19)). Among autologous cycle starts, cycles in women with a history of cancer were less likely to result in CIG compared to no history of cancer (aRR: 0.73 (0.65-0.83)); this relationship was absent from donor cycles (aRR: 1.01 (0.85-1.20)). Once achieving CIG, donor cycles for women with a history of cancer were two times more likely to result in pregnancy loss (aRR: 1.99 (1.26-3.16)). CONCLUSIONS: Our analysis suggests that cancer may influence ovarian stimulation response, requiring more FSH and resulting in lower CIG among cycle starts.

PURPOSE: Investigate the relationship between history of cancer and adverse pregnancy outcomes according to subfertility/fertility treatment. METHODS: Deliveries (2004-2013) from Massachusetts (MA) Registry of Vital Records and Statistics were linked to MA assisted reproductive technology data, hospital discharge records, and Cancer Registry. The relative risks (RR) and 95% confidence intervals of adverse outcomes (gestational diabetes (GDM), gestational hypertension (GHTN), cesarean section (CS), low birth weight (LBW), small for gestational age (SGA), preterm birth (PTB), neonatal mortality, and prolonged neonatal hospital stay) were modeled with log-link and Poisson distribution generalized estimating equations. Differences by history of subfertility/fertility treatment were investigated with likelihood ratio tests. RESULTS: Among 662,630 deliveries, 2,983 had a history of cancer. Women with cancer history were not at greater risk of GDM, GHTN, or CS. However, infants born to women with prior cancer had higher risk of LBW (RR: 1.19 [1.07-1.32]), prolonged neonatal hospital stay (RR: 1.16 [1.01-1.34]), and PTB (RR: 1.19 [1.07-1.32]). We found clinically and statistically significant differences in the relationship between cancer history and SGA by subfertility/fertility treatment (p value, test for heterogeneity = 0.02); among deliveries with subfertility or fertility treatment, those with a history of cancer experienced a greater risk of SGA (RRsubfertile: 1.36 [1.02-1.83]). CONCLUSIONS: Women with a history of cancer had greater risk of some adverse pregnancy outcomes; this relationship varied by subfertility and fertility treatment.

OBJECTIVE: To assess trends in racial disparity in supine sleep positioning (SSP) across racial/ethnic groups of infants born early preterm (Early preterm; <34 weeks) and late preterm (Late preterm; 34-36 weeks) from 2000 to 2015. STUDY DESIGN: We analyzed Pregnancy Risk Assessment Monitoring System data (a population-based perinatal surveillance system) from 16 US states from 2000 to 2015 (Weighted N = 1 020 986). Marginal prevalence of SSP by year was estimated for infants who were early preterm and late preterm, adjusting for maternal and infant characteristics. After stratifying infants who were early preterm and late preterm, we compared the aOR of SSP trends across racial/ethnic groups by testing the time-race interaction. RESULTS: From 2000 to 2015, Non-Hispanic Black infants had lower odds of SSP compared with Non-Hispanic White infants for early preterm (aOR 0.61; 95% CI 0.47-0.78) and late preterm (aOR 0.44; 95% CI 0.34-0.56) groups. For Hispanic infants, there was no statistically significant difference for either preterm group when compared with Non-Hispanic White infants. aOR of SSP increased (on average) annually by 10.0%, 7.3%, and 7.7%, respectively, in Non-Hispanic White, Non-Hispanic Black, and Hispanic early preterm infants and by 5.8%, 5.9%, and 4.8% among Non-Hispanic White, Non-Hispanic Black, and Hispanic late preterm infants. However, there were no significant between-group differences in annual changes (Early preterm: P = .11; Late preterm: P = .25). CONCLUSIONS: SSP increased for all racial/ethnic preterm groups from 2000 to 2015. However, the racial/ethnic disparity in SSP among early preterm and late preterm groups persists.

OBJECTIVE: To determine the risk factors for receipt of emergency room (ER) care and rehospitalization among opioid-exposed newborns in Massachusetts. DESIGN/METHODS: We analyzed two linked data sets from 2002 to 2010: (a) Massachusetts Pregnancy to Early Life Longitudinal Data System and (b) Massachusetts Bureau of Substance Abuse Services Management Information System. Generalized estimating equations were used to assess the independent association of maternal and infant characteristics with ER use and rehospitalization in the first year of life. RESULTS: Four thousand and five hundred and twenty-four maternal-infant dyads affected by OUD were included in the analysis. In adjusted analysis, risk factors for receipt of ER care included Hispanic ethnicity (aOR 1.63 [95% CI 1.30-2.05]), lower education levels (aOR 1.54-1.69 [95% CI 1.12-2.31]), nonprivate insurance (aOR 1.44 [95% CI 1.11-1.86]), and presence of maternal chronic conditions (aOR 1.14 [95% CI 1.01-1.29]). Risk factors for rehospitalization included prematurity (aOR 1.44 [95% CI 1.14-1.82]), low birthweight (aOR 2.02 [95% CI 1.63-2.49]), and nonprivate insurance (aOR 1.58 [95% CI 1.13-2.22]). Prolonged infant birth hospitalization was protective against both ER use (aOR 0.84 [95% CI 0.73-0.96]) and rehospitalization (aOR 0.63 [95% CI 0.53-0.75]). CONCLUSIONS: Clinical and sociodemographic characteristics are risk factors for receipt of ER care and rehospitalization among opioid-exposed newborns in Massachusetts.

PURPOSE: Among infants following ART-treated, subfertile, and fertile deliveries to determine (1) the presence and magnitude of sex differences in health outcomes and (2) whether the presence of sex differences varied among maternal fertility groups. METHODS: Retrospective cohort analysis of infants born in Massachusetts (MA) in 2004-2013 who were conceived by ART. The Society for Assisted Reproductive Technology Clinic Outcome Reporting System was linked to the Pregnancy to Early Life Longitudinal data system, which links birth certificates to hospital discharge records for MA mothers and infants. Included were singletons born via ART-treated, subfertile, and fertile deliveries. Multivariable logistic regression was used to model the association between infant sex and health outcomes, controlling for maternal demographic and health characteristics. RESULTS: A total of 16,034 ART-treated, 13,277 subfertile, and 620,375 fertile singleton live births were included. For all three groups, males had greater odds of being preterm (AOR range 1.15-1.2), having birth defects (AOR range 1.31-1.71), experiencing respiratory (AOR range 1.33-1.35) and neurologic (AOR range 1.24-1.3) conditions, and prolonged hospital stay (AOR range 1.19-1.25) compared to females. The interaction between maternal fertility group and infant sex for all infant outcomes was nonsignificant, denoting that the presence of sex differences among fertile, subfertile, and ART groups did not vary. CONCLUSION: Sex differences in birth outcomes of infants following ART-treated, subfertile, and fertile deliveries exist but the magnitude of these differences does not vary among these maternal fertility groups.

PURPOSE: We previously developed a subfertile comparison group with which to compare outcomes of assisted reproductive technology (ART) treatment. In this study, we evaluated whether insurance claims data in the Massachusetts All Payers Claims Database (APCD) defined a more appropriate comparison group. METHODS: We used Massachusetts vital records of women who delivered between 2013 and 2017 on whom APCD data were available. ART deliveries were those linked to a national ART database. Deliveries were subfertile if fertility treatment was marked on the birth certificate, had prior hospitalization with ICD code for infertility, or prior fertility treatment. An infertile group included women with an APCD outpatient or inpatient ICD 9/10 infertility code prior to delivery. Fertile deliveries were none of the above. Demographics, health risks, and obstetric outcomes were compared among groups. Multivariable generalized estimating equations were used to calculate adjusted relative risk (aRR) and 95% confidence intervals (CI). RESULTS: There were 70,726 fertile, 4,763 subfertile, 11,970 infertile, and 7,689 ART-treated deliveries. Only 3,297 deliveries were identified as both subfertile and infertile. Both subfertile and infertile were older, and had more education, chronic hypertension, and diabetes than the fertile group and less than the ART-treated group. Prematurity (aRR = 1.15-1.17) and birthweight (aRR = 1.10-1.21) were increased in all groups compared with the fertile group. CONCLUSION: Although the APCD allowed identification of more women than the previously defined subfertile categorization and allowed us to remove previously unidentified infertile women from the fertile group, it is not clear that it offered a clinically significantly improved comparison group.

OBJECTIVE: To evaluate the association between neonatal intensive care unit (NICU) admission and breastfeeding practices, infant supine sleep positioning, and postnatal smoking among mothers of late preterm infants. STUDY DESIGN: Data from 36 states using the 2000-2013 Pregnancy Risk Assessment Monitoring System were analyzed. χ2 tests and 95% CI assessed infant and maternal characteristics and recommended care practices for late preterm infants based on NICU admission after birth. Adjusted prevalence ratios (APR) for breastfeeding initiation and continuation at 10 weeks, supine sleep position, and postnatal smoking were estimated using multivariable logistic regression models, controlling for infant and maternal characteristics. Analyses were weighted and SEs accounted for the complex survey design. RESULTS: Our sample included 62 494 late preterm infants, representing a weighted population of 1 441 451 late preterm infants. In the adjusted analysis, mothers of late preterm infants admitted to a NICU were more likely to initiate breastfeeding (APR 1.07; 95% CI 1.05-1.09) and place their infants in supine sleep position (1.04; 95% CI 1.01-1.06) than mothers of late preterm infants not admitted to a NICU. There was no significant difference between groups for breastfeeding continuation or postnatal smoking. CONCLUSIONS: Mothers of late preterm infants admitted to a NICU were more likely to initiate breastfeeding and practice supine sleep position than mothers of late preterm infants not admitted to a NICU. Future work should seek to identify the drivers of these differences to develop effective strategies to engage mothers in these health promoting infant care practices.

Differences in preterm birth rates between black and white women are the largest contributor to racial disparities in infant mortality. In today's age of precision medicine, analysis of the genome, epigenome, metabolome, and microbiome has generated interest in determining whether these biomarkers can help explain racial disparities. We propose that there are pitfalls as well as opportunities when using precision medicine analyses to interrogate disparities in health. To conclude that racial disparities in complex conditions are genetic in origin ignores robust evidence that social and environmental factors that track with race are major contributors to disparities. Biomarkers measured in omic assays that may be more environmentally responsive than genomics, such as the epigenome or metabolome, may be on the causal pathway of race and preterm birth, but omic observational studies suffer from the same limitations as traditional cohort studies. Confounding can lead to false conclusions about the causal relationship between omics and preterm birth. Methodological strategies (including stratification and causal mediation analyses) may help to ensure that associations between biomarkers and exposures, as well as between biomarkers and outcomes, are valid signals. These epidemiologic strategies present opportunities to assess whether precision medicine biomarkers can uncover biology underlying perinatal health disparities.

BACKGROUND: Family-centered care (FCC) in neonatal intensive care units (NICUs) was initiated in 1992 to promote a respectful response to individual family needs and support parental participation in care and decision-making for their infants. Although benefits of FCC have been reported, changes in the maternal experience in the NICU are unknown. PURPOSE: The purpose of this study was to compare mothers' experiences in NICUs where FCC is the standard of care and to compare these with the experiences of mothers 2 decades ago. METHODS: In this qualitative descriptive design, mothers of infants born under 32 weeks postconceptional age were asked to describe their experiences with their infant's birth and hospitalization. Open-ended probing questions clarified maternal responses. Saturation was reached after 14 interviews. Iterative coding and thematic grouping was used for analysis. RESULTS: Common themes that emerged were: (1) visiting; (2) general caregiving; (3) holding; (4) feeding; and (5) maternal ideas for improvement. Findings indicated important improvements in privacy, mother-nurse relationship, ease of visiting, and maternal knowledge and participation in infant caregiving. IMPLICATIONS FOR PRACTICE: Mothers suggested improvements such as additional comforts in private rooms, areas in the NICU where they can meet other mothers, and early information on back-transport. Better recognition and response for mothers without adequate social support would provide much needed emotional assistance. IMPLICATIONS FOR RESEARCH: Future research addressing benefits of webcams, wireless monitors, back-transport, maternity leave, and accommodations for extended visiting for siblings would address other needs mentioned by mothers.

Objectives To describe the demographics, clinical characteristics and referral patterns of premature infants to a regional level IV neonatal intensive care unit (NICU); to determine the prevalence and predictors of back-transport of infants ≤ 32 weeks gestational age in a level IV NICU; for infants not back-transported closer to maternal residence, determine the length of stay beyond attainment of clinical stability. Methods Data (2010-2014) from the Children's Hospital Neonatal Database and individual chart review for infants ≤ 32 weeks admitted to a level IV NICU whose maternal residence was outside the metro area were included. Bivariate associations of maternal and infant characteristics with back-transport were estimated using two-sample t tests and Fisher's exact test. Multivariable logistic regression was used to measure independent predictors of back-transport. Clinical stability was defined as the attainment of full volume enteral feedings and low flow nasal cannula. Results A total of 223 infants were eligible for analysis; of whom 26% were back-transported after acute care. In the adjusted analysis, insurance status, distance from maternal residence and gestational age were significantly associated with back-transport. For infants not back-transported closer to maternal residence, median length of stay in the level IV NICU beyond attainment of clinical stability was 28.5 days. Conclusion for Practice Predictors of back-transport include private insurance, greater distance of maternal residence from NICU and younger gestational age. Many preterm infants admitted to a regional NICU for acute care remained hospitalized in a level IV NICU after achieving clinical stability, for which care in a NICU closer to maternal residence may be appropriate.

OBJECTIVE: To determine the association of maternal substance use disorders (SUDs) during pregnancy with adverse neonatal outcomes and infant hospital re-admissions, observational stays, and emergency department utilization in the first year of life. STUDY DESIGN: We analyzed 2 linked statewide datasets from 2002 to 2010: the Massachusetts Pregnancy to Early Life Longitudinal data system and the Massachusetts Bureau of Substance Abuse Services Management Information System. Generalized estimating equations were used to assess the association of maternal SUDs and neonatal outcomes and infant hospital-based care in the first year of life, controlling for maternal and infant characteristics. RESULTS: Maternal SUDs increased from 19.4 per 1000 live births in 2003 to 31.1 per 1000 live births in 2009. In the adjusted analysis, exposed neonates were more likely to be born preterm (aOR 1.85; 95% CI 1.75-1.96) and low birthweight (aOR 1.94; 95% CI 1.80-2.09). After controlling for maternal characteristics and preterm birth, SUD-exposed neonates were more likely to have intrauterine growth restriction, cardiac, respiratory, neurologic, infectious, hematologic, and feeding/nutrition problems, prolonged hospital stay, and higher mortality (aOR range 1.26-3.80). Exposed infants were more likely to be rehospitalized (aOR 1.10; 95% CI 1.04-1.17) but less likely to have an observational stay (aOR 0.90; 95% CI 0.82-0.99) or use the emergency department (aOR 0.87; 95% CI 0.83-0.90) in the first year of life. CONCLUSIONS: Infants born to mothers with SUD are at higher risk for adverse health outcomes in the perinatal period and are also more likely to be rehospitalized in the first year of life.
