Racial differences within subsets of Sudden Unexpected Infant Death (SUID) with an emphasis on asphyxia

Community-based approaches to infant safe sleep and breastfeeding promotion: a qualitative study

BACKGROUND

In the U.S., sudden unexpected infant deaths (SUID) due to accidental suffocation and strangulation in bed (ASSB) are increasing, with disparities by race/ethnicity. While breastfeeding is a protective factor against infant mortality, racial/ethnic disparities are present in its uptake, and motivations to breastfeed are also often coupled with non-recommended infant sleep practices that are associated with infant sleep deaths. Combining infant safe sleep (ISS) and breastfeeding promotion on the community level presents opportunities to address racial/ethnic disparities and associated socioeconomic, cultural, and psychosocial influences.

METHODS

We completed a descriptive qualitative hermeneutical phenomenology using thematic analysis of focus group data. We examined the phenomenon of community-level providers promoting ISS and breastfeeding in communities vulnerable to ISS and breastfeeding disparities. We asked eighteen informants participating in a national quality improvement collaborative about i.) areas requiring additional support to meet community needs around ISS and breastfeeding, and ii.) recommendations on tools to improve their work promoting ISS and breastfeeding.

RESULTS

We identified four themes: i.) education and dissemination, ii.) relationship building and social support, iii.) working with clients' personal circumstances and considerations, and iv.) tools and systems.

CONCLUSIONS

Our findings support embedding risk-mitigation approaches in ISS education; relationship building between providers, clients, and peers; and the provision of ISS and breastfeeding supportive material resources with educational opportunities. These findings may be used to inform community-level provider approaches to ISS and breastfeeding promotion.

Maternity Care Clinicians' Experiences Promoting Infant Safe Sleep and Breastfeeding During the COVID-19 Pandemic

OBJECTIVE

To explore the phenomenon of clinicians' perceptions and experiences of promoting infant safe sleep (ISS) and breastfeeding during the COVID-19 pandemic.

DESIGN

Descriptive qualitative hermeneutical phenomenology of key informant interviews conducted as part of a quality improvement initiative.

SETTING

Maternity care services of 10 U.S. hospitals from April through September 2020.

PARTICIPANTS

Ten hospital teams, including 29 clinicians.

INTERVENTION

Participants were part of a national quality improvement intervention focused on promoting ISS and breastfeeding. Participants were asked about challenges and opportunities promoting ISS and breastfeeding during the pandemic.

RESULTS

We identified four themes summarizing the experiences and perceptions of clinicians promoting ISS and breastfeeding in the COVID-19 pandemic: Strain on Clinicians Related to Hospital Policies, Coordination, and Capacity; Effects of Isolation for Parentsin Labor and Delivery; ReevaluatingOutpatient Follow-Up Care andSupport; and AdoptingShared Decision-Makingaround ISS andBreastfeeding.

CONCLUSIONS

Our results support the need for physical and psychosocial care to reduce crisis-related burnout for clinicians to encourage the continued provision of ISS and breastfeeding education, particularly while navigating capacity constraints. Our findings also suggest that clinicians perceived that parents may require additional support to enhance potentially limited ISS and breastfeeding education. These findings may be used to inform approaches to parental and clinician maternity care support in future public health crises.

Risk Factors for Suffocation and Unexplained Causes of Infant Deaths

BACKGROUND

Observational studies have improved our understanding of the risk factors for sudden infant death syndrome, but separate examination of risk for sleep-related suffocation and unexplained infant deaths has been limited. We examined the association between unsafe infant sleep practices and sudden infant deaths (sleep-related suffocation and unexplained causes including sudden infant death syndrome).

METHODS

We conducted a population-based case-control study using 2016 to 2017 Centers for Disease Control and Prevention data. Controls were liveborn infants from the Pregnancy Risk Assessment Monitoring System; cases were from the Sudden Unexpected Infant Death Case Registry. We calculated risk factor prevalence among cases and controls and crude and adjusted odds ratios.

RESULTS

We included 112 sleep-related suffocation cases with 448 age-matched controls and 300 unexplained infant death cases with 1200 age-matched controls. Adjusted odds for sleep-related suffocation ranged from 18.7 (95% confidence interval [CI]: 6.8-51.3) among infants not sharing a room with their mother or caregiver to 1.9 (95% CI: 0.9-4.1) among infants with nonsupine sleep positioning. Adjusted odds for unexplained death ranged from 7.6 (95% CI: 4.7-12.2) among infants not sharing a room with their mother or caregiver to 1.6 (95% CI: 1.1-2.4) among nonsupine positioned infants.

COCLUSIONS

We confirmed previously identified risk factors for unexplained infant death and independently estimated risk factors for sleep-related suffocation. Significance of associations for suffocation followed similar patterns but was of larger magnitude. This information can be used to improve messaging about safe infant sleep.

Half Century Since SIDS: A Reappraisal of Terminology

After a sudden infant death, parents and caregivers need accurate and open communication about why their infant died. Communicating tragic news about a child's death to families and caregivers is difficult. Shared and consistent terminology is essential for pediatricians, other physicians, and nonphysician clinicians to improve communication with families and among themselves. When families do not have complete information about why their child died, pediatricians will not be able to support them through the process and make appropriate referrals for pediatric specialty and mental health care. Families can only speculate about the cause and may blame themselves or others for the infant's death. The terminology used to describe infant deaths that occur suddenly and unexpectedly includes an assortment of terms that vary across and among pediatrician, other physician, or nonphysician clinician disciplines. Having consistent terminology is critical to improve the understanding of the etiology, pathophysiology, and epidemiology of these deaths and communicate with families. A lack of consistent terminology also makes it difficult to reliably monitor trends in mortality and hampers the ability to develop effective interventions. This report describes the history of sudden infant death terminology and summarizes the debate over the terminology and the resulting diagnostic shift of these deaths. This information is to assist pediatricians, other physicians, and nonphysician clinicians in caring for families during this difficult time. The importance of consistent terminology is outlined, followed by a summary of progress toward consensus. Recommendations for pediatricians, other physicians, and nonphysician clinicians are proposed.

Supporting African American Mothers during Nurse Home Visits in Adopting Safe Sleep Practices

BACKGROUND

Nurses providing home visits were concerned that some mothers were not routinely using safe sleep practices for their newborns and infants.

PURPOSE

The purpose of this study was to listen to how home visit nurses offer education to their African American clients about the safe to sleep guidelines during the prenatal and postpartum periods and discuss ways nurses could support mothers to be more successful in using safe sleep practices.

STUDY DESIGN AND METHODS

A focus group was conducted with home visit nurses who partner with pregnant mothers and follow them through the first 2 years of their child's life. We asked the nurses to discuss how they offer information and education to their African American clients about safe sleep practices and what could be done to support adoption of the guidelines. A qualitative narrative approach was used for data analysis.

RESULTS

Seventeen home visit nurses participated in the focus group. We identified two overall themes with eight subthemes. The first theme focused on nurses' perceptions about challenges some mothers have in following the recommendations. The second theme included nurses' perspectives on how to better promote the safe sleep message and educating mothers within their cultural context.

CLINICAL IMPLICATIONS

Expectant and new mothers need advice and knowledge about the Safe to Sleep guidelines that provide ways to decrease risk of infant death. Nurses must be aware of their clients' culture and beliefs so they can offer support and information on infant safety within that context.

T-Wave Alternans in Nonpathological Preterm Infants

BACKGROUND

Sudden infant death syndrome is more frequent in preterm infants (PTI) than term infants and may be due to cardiac repolarization instability, which may manifest as T-wave alternans (TWA) on the electrocardiogram (ECG). Therefore, the aim of the present work was to analyze TWA in nonpathological PTI and to open an issue on its physiological interpretation.

METHODS

Clinical population consisted of ten nonpathological PTI (gestational age ranging from 29 3 7 to 34 2 7  weeks; birth weight ranging from 0.84 to 2.10 kg) from whom ECG recordings were obtained ("Preterm infant cardio-respiratory signals database" by Physionet). TWA was identified through the heart-rate adapting match filter method and characterized in terms of mean amplitude values (TWAA). TWA correlation with several other clinical and ECG features, among which gestational age-birth weight ratio, RR interval, heart-rate variability, and QT interval, was also performed.

RESULTS

TWA was variable among infants (TWAA = 26 ± 11 µV). Significant correlations were found between TWAA versus birth weight (ρ = -0.72, p = .02), TWAA versus gestational age-birth weight ratio (ρ = 0.76, p = .02) and TWAA versus heart-rate variability (ρ = -0.71, p = .02).

CONCLUSIONS

Our preliminary retrospective study suggests that nonpathological PTI show TWA of few tens of µV, the interpretation of which is still an open issue but could indicate a condition of cardiac risk possibly related to the low development status of the infant. Further investigations are needed to solve this issue.
