Toward a national strategy on infant mortality

Participant Perspectives on a Community Health Worker Intervention to Reduce Infant Mortality: A Mixed Methods Assessment of the Bronx Healthy Start Partnership

INTRODUCTION

Healthy Start is an initiative to reduce infant mortality and improve birth equity throughout the US, in large part by deploying community health workers (CHWs) to conduct home visits and provide educational and emotional support to new and expectant parents.

METHODS

A mixed-methods assessment of the Bronx Healthy Start Partnership (BxHSP) was conducted as part of a quality improvement initiative to understand client perspectives regarding the impact of BxHSP on short- and intermediate-term outcomes that affect long-term well-being. Phone interviews (n = 16) and online surveys (n = 62) were conducted in English and Spanish with BxHSP participants in 2020 and 2022. The interview sample was selected purposefully; interview participants were eligible if they gave birth prior to mid-March 2020 and had received at least one CHW home visit. All individuals with open BxHSP cases (n = 379) were invited to complete the survey.

RESULTS

Findings suggest that BxHSP CHWs can provide vital psychosocial, material, and educational resources that help engaged participants feel supported as new parents and develop knowledge and skills related to infant care. Results further suggest that these short-term outcomes contribute to lower stress, increased self-efficacy, and health-promoting infant care practices, enabling participants to feel more confident and capable as new parents.

DISCUSSION

Findings underscore how programs like BxHSP can help address gaps in resources and improve health and well-being for pregnant and postpartum participants. Limitations include possible selection, recall, and/or social desirability biases as response rates were low and data were self-reported and retrospective. Limitations were addressed in part through triangulation of qualitative and quantitative data.

Structural Bias in the Completeness of Death Investigations for Sudden Unexpected Infant Deaths (SUIDs)

OBJECTIVE

To assess sudden unexpected infant death (SUID) investigations for structural inequities by race/ethnicity and geography.

METHODS

The SUID Case Registry compiles data on death investigations. We analyzed cases from 2015 to 2018 (N = 3847) to examine likelihood of an incomplete death investigation, defined as missing autopsy, missing scene investigation, or missing detailed information about where and how the body was found. We also analyzed which specific components of death investigations led to the greatest number of incomplete investigations.

RESULTS

Twenty-four percent of SUIDs had incomplete death investigations. Death scenes in rural places had 1.51 times the odds of incomplete death investigations (95% confidence interval [CI], 1.19-1.92) compared with urban areas. Scene investigations led by law enforcement were more likely to result in incomplete death investigations (odds ratio [OR] = 1.49; 95% CI, 1.18-1.88) than those led by medical examiners. American Indian/Alaska Native SUIDs were more likely than other racial groups to have an incomplete investigation (OR = 1.49; 95% CI, 0.92-2.42), more likely to occur in rural places ( P = .055), and more likely to be investigated by law enforcement ( P < .001). If doll reenactments had been performed, 358 additional cases would have had complete investigations, and if SUID investigation forms had been performed, 243 additional cases would have had complete investigations. American Indian/Alaska Native SUIDs were also more likely to be missing specific components of death investigations.

CONCLUSION

To produce equitable public health surveillance data used in prevention efforts, it is crucial to improve SUID investigations, especially in rural areas and among American Indian/Alaska Native babies.

Using Collective Impact to Develop a Community-Led Initiative for Improving Black Infant Mortality

The United States has one of the highest infant mortality rates among developed countries. When stratified by race, disparities are more evident: Black infant mortality rates are 2.5 times higher than non-Hispanic white infants. Structural, systemic racism is a contributing cause for these racial disparities. Multisector collaborations focused on a common agenda, often referred to as collective impact, have been used for infant mortality reduction interventions. In addition, community-based participatory approaches have been applied to incorporate those with lived experience related to adverse pregnancy outcomes. This article critically describes the transition of an infant mortality collective impact initiative from being led by a multisector organizational group to being community led over a 5-year period, 2015-2020. A 34-member community leaders group was developed and determined four priorities and corresponding strategies for the initiative. Findings show that community participatory approaches are a way to address racial equity for public health initiatives.

Breastfeeding Initiation Trends by Special Supplemental Nutrition Program for Women, Infants, and Children Participation and Race/Ethnicity Among Medicaid Births

OBJECTIVE

Describe long-term breastfeeding initiation trends by prenatal Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation and race/ethnicity.

DESIGN

Cross-sectional study of birth certificate data from 2009 to 2017 in 24 states that adopted the 2003 birth certificate revision by 2009.

PARTICIPANTS

Term births with hospital costs covered by Medicaid (N = 6,402,704).

MAIN OUTCOME MEASURES

Breastfeeding initiation.

ANALYSIS

The descriptive characteristics of WIC participants and WIC-eligible nonparticipants were compared by year and race/ethnicity using the chi-square test of independence or t tests. Adjusted breastfeeding initiation prevalence was estimated using linear regression models with county fixed effects, controlling for sociodemographic and obstetric/health factors. Trends were compared by WIC status overall and within racial/ethnic groups. Differences and P values were assessed using interaction terms between WIC and year.

RESULTS

Breastfeeding initiation increased for WIC participants and nonparticipants. Special Supplemental Nutrition Program for Women, Infants, and Children participants had lower adjusted breastfeeding initiation (2009: 69.0%; 2017: 78.5%) than nonparticipants (2009: 70.8%; 2017: 80.1%) (P < 0.001 per year). Breastfeeding initiation increased more rapidly in WIC participants than in nonparticipants for non-Hispanic Asian/Pacific Islander (21.4% and 8.6%, respectively; P < 0.001) and American Indian/Alaskan Native (13.6% and 8.1%, respectively; P = 0.02)-narrowing the gap between WIC participants and nonparticipants over time.

CONCLUSIONS AND IMPLICATIONS

Annual birth certificate data provide detailed information for monitoring trends and disparities in breastfeeding initiation by prenatal WIC status. These findings can inform WIC and maternal child health program efforts to improve breastfeeding promotion for populations with low-income and racial/ethnic groups.

Pregnancy health and perinatal outcomes among Pacific Islander women in the United States and US Affiliated Pacific Islands: Protocol for a scoping review

This scoping review examines the literature on pregnancy and perinatal outcomes among Pacific Islander women in the United States (U.S.) and U.S.-affiliated Pacific Islands. Our aim was to identify research that disaggregated Pacific Islanders from other population groups. We conducted a systematic search of MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCO), and PsycINFO (Ovid) databases and a hand-search of grey literature. Forty-eight articles published between January 2010 and June 2020 were included. The majority of studies were conducted in Hawaii and utilized clinical record data. Infant outcomes were more commonly reported than maternal outcomes. We highlighted several limitations of the existing literature that included aggregation of Pacific Islanders with Asian American and other ethnic groups; limited comparison between Pacific Islander sub-groups; inadequate definitions of the nationality and ethnic composition of Pacific Islander groups; a lack of hypothesis-driven primary data collection and clinical trials; and underrepresentation of Pacific Islanders in population-based studies. Researchers should address these limitations to improve pregnancy and perinatal outcomes among Pacific Islanders, who comprise the second fastest growing ethnic minority in the U.S.

State and Local Government Expenditures and Infant Mortality in the United States

BACKGROUND AND OBJECTIVES

Evidence suggests that government expenditures on non-health care services can reduce infant mortality, but it is unclear what types of spending have the greatest impact among groups at highest risk. Thus, we sought to quantify how US state government spending on various services impacted infant mortality rates (IMRs) over time and whether spending differentially reduced mortality in some subpopulations.

METHODS

A longitudinal, repeated-measures study of US state-level infant mortality and state and local government spending for the years 2000-2016, the most recent data available. Expenditures included spending on education, social services, and environment and housing. Using generalized linear regression models, we assessed how changes in spending impacted infant mortality over time, overall and stratified by race and ethnicity and maternal age group.

RESULTS

State and local governments spend, on average, $9 per person. A $0.30 per-person increase in environmental spending was associated with a decrease of 0.03 deaths per 1000 live births, and a $0.73 per-person increase in social services spending was associated with a decrease of 0.02 deaths per 1000 live births. Infants born to mothers aged <20 years had the single greatest benefit from an increase in expenditures compared with all other groups. Increased expenditures in public health, housing, parks and recreation, and solid waste management were associated with the greatest reduction in overall IMR.

CONCLUSIONS

Investment in non-health care services was associated with lower IMRs among certain high-risk populations. Continued investments into improved social and environmental services hold promise for further reducing IMR disparities.

Families as a Cornerstone in 21st Century Public Health: Recommendations for Research, Education, Policy, and Practice

Families are vastly overlooked in US initiatives to promote population health and health equity despite being the most proximal context for health across the life course. We urge the public health sector to take the lead in recognizing families as essential for promoting 21st century population health. We highlight ways families influence health by providing context, care, continuity, and connections. The dual private and public aspect of families has contributed to how they have been overlooked in the public health sector. We provide recommendations for better integrating families into population health initiatives through national health goals, research, education, policy, and practice.

Moving Toward Paying for Outcomes in Medicaid

Medicaid can improve beneficiary health and help sustain its own future by embracing payment for outcomes. Good precedents exist from states such as Florida, Maryland, Minnesota, New York, Ohio, Pennsylvania, and Texas. Medicaid outcome measures include preventable admissions, readmissions, emergency department visits, and inpatient complications; early elective deliveries; infant and child mortality; patient-reported outcomes, satisfaction, and confidence; and reduction in low-value care. Criteria to prioritize initiatives include potential savings, availability of established models, impact on health status, and Medicaid's ability to effect change. We offer 5 principles for success, emphasizing clinically credible initiatives that generate actionable information for clinicians.

Joinpoint Trend Analysis of Infant Mortality Disparities in Wisconsin, 1999-2016

OBJECTIVES

To address shortcomings of previous research exploring trends in racial, educational, and race by educational disparities in infant mortality rates (IMRs) by using nonlinear methods to compare improvement within and between disparity domains.

METHODS

We used joinpoint regression modeling to perform a cross-sectional analysis of IMR trends from linked birth and death certificates in Wisconsin between 1999 and 2016.

RESULTS

In the race and education domains, IMR decreased by 1.9% per year for infants of White mothers and 1.1% per year for infants of less-educated mothers. Further analysis showed these IMR reductions to be among infants of White mothers with more education (-0.6%/year) and Black mothers with less education (-2.0%/year).

CONCLUSIONS

As previously reported, gaps in IMR by race and education in Wisconsin appear to be closing; however, only the change by education is statistically significant. Evidence suggests the racial divide in IMR might soon widen after years of progress in reducing IMR among infants of Black mothers. Public Health Implications. Those advancing strategies to address IMR disparities should pursue data and methods that provide the most accurate and refined information about the challenges that persist and progress that has been realized.

The Use of a Community-Based Preconception Peer Health Educator Training Intervention to Improve Preconception Health Knowledge

This paper highlights the use of an adapted Office of Minority Health (OMH) Preconception Health Peer Educator program to address persistent infant mortality health disparities. The community-based Attack Infant Mortality (AIM Escambia) initiative was established to increase preconception health knowledge among African American women at risk for adverse birth outcomes. Participants (N = 122) attended a 6-h AIM peer educator training, completed pretest and posttest questionnaires about their health knowledge, health attitudes, and planned engagement in health behaviors. Study results support the use of preconception health education training to inform health knowledge, health attitudes, and planned health sharing behaviors. Multidisciplinary collaborations and targeted interventions should be considered when seeking to improve community health conditions and increase health knowledge and health literacy for minority populations.

Medicaid Accountable Care Organizations and Childbirth Outcomes

Some states have adopted Accountable Care Organization (ACO) models to transform their Medicaid programs, but little is known about their impact on health care outcomes and costs. Medicaid ACOs are uniquely positioned to improve childbirth outcomes because of the number of births covered by Medicaid. Using Healthcare Cost and Utilization Project hospital data, we examined the relationship between ACO adoption and (a) neonatal and maternal outcomes, and (b) cost per birth. We compared outcomes in states that have adopted ACO models in their Medicaid programs with adjacent states without ACO models. Implementation of Medicaid ACOs was associated with a moderate reduction in hospital costs per birth and decreased cesarean section rates. Results varied by state. We found no association between Medicaid ACOs and several birth outcomes, including infant inpatient mortality, low birthweight, neonatal intensive care unit utilization, and severe maternal morbidity. Improving these outcomes may require more time or targeted interventions.

State Medicaid Expansions for Parents Led to Increased Coverage and Prenatal Care Utilization among Pregnant Mothers

OBJECTIVE

To evaluate impacts of state Medicaid expansions for low-income parents on the health insurance coverage, pregnancy intention, and use of prenatal care among mothers who became pregnant.

DATA SOURCES/STUDY SETTING

Person-level data for women with a live birth from the 1997-2012 Pregnancy Risk Assessment Monitoring System.

DATA COLLECTION/EXTRACTION METHODS

The sample was restricted to women who were already parents using information on previous live births and combined with information on state Medicaid policies for low-income parents.

STUDY DESIGN

I used a measure of expanded generosity of state Medicaid eligibility for low-income parents to estimate changes in health insurance, pregnancy intention, and prenatal care for pregnant mothers associated with Medicaid expansion.

PRINCIPAL FINDINGS

I found an increase in prepregnancy health insurance coverage and coverage during pregnancy among pregnant mothers, as well as earlier initiation of prenatal care, associated with the expansions. Among pregnant mothers with less education, I found an increase in the adequacy of prenatal care utilization.

CONCLUSIONS

Expanded Medicaid coverage for low-income adults has the potential to increase a woman's health insurance coverage prior to pregnancy, as well as her insurance coverage and medical care receipt during pregnancy.

Applying Collaborative Learning and Quality Improvement to Public Health: Lessons from the Collaborative Improvement and Innovation Network (CoIIN) to Reduce Infant Mortality

OBJECTIVES

Infant mortality remains a significant public health problem in the U.S. The Collaborative Improvement & Innovation Network (CoIIN) model is an innovative approach, using the science of quality improvement and collaborative learning, which was applied across 13 Southern states in Public Health Regions IV and VI to reduce infant mortality and improve birth outcomes. We provide an in-depth discussion of the history, development, implementation, and adaptation of the model based on the experience of the original CoIIN organizers and participants. In addition to the political genesis and functional components of the initiative, 8 key lessons related to staffing, planning, and implementing future CoIINs are described in detail.

METHODS

This paper reports the findings from a process evaluation of the model. Data on the states' progress toward reducing infant mortality and improving birth outcomes were collected through a survey in the final months of a 24-month implementation period, as well as through ongoing team communications.

RESULTS

The peer-to-peer exchange and platform for collaborative learning, as well as the sharing of data across the states, were major strengths and form the foundation for future CoIIN efforts. A lasting legacy of the initiative is the unique application and sharing of provisional "real time" data to inform "real time" decision-making.

CONCLUSION

The CoIIN model of collaborative learning, QI, and innovation offers a promising approach to strengthening partnerships within and across states, bolstering data systems to inform and track progress more rapidly, and ultimately accelerating improvement toward healthier communities, States, and the Nation as a whole.

Political gender inequality and infant mortality in the United States, 1990-2012

Although gender inequality has been recognized as a crucial factor influencing population health in the developing world, research has not yet thoroughly documented the role it may play in shaping U.S. infant mortality rates (IMRs). This study uses administrative data with fixed-effects and random-effects models to (1) investigate the relationship between political gender inequality in state legislatures and state infant mortality rates in the United States from 1990 to 2012, and (2) project the population level costs associated with women's underrepresentation in 2012. Results indicate that higher percentages of women in state legislatures are associated with reduced IMRs, both between states and within-states over time. According to model predictions, if women were at parity with men in state legislatures, the expected number of infant deaths in the U.S. in 2012 would have been lower by approximately 14.6% (3,478 infant deaths). These findings underscore the importance of women's political representation for population health.

Preconception Maternal Bereavement and Infant and Childhood Mortality: A Danish Population-Based Study

OBJECTIVES

Preconception maternal bereavement may be associated with an increased risk for infant mortality, although these previously reported findings have not been replicated. We sought to examine if the association could be replicated and explore if risk extended into childhood.

METHODS

Using a Danish population-based sample of offspring born 1979 to 2009 (N = 1,865,454), we analyzed neonatal (0-28 days), postneonatal infant (29-364 days), and early childhood (1-5 years) mortality after maternal bereavement in the preconception (6-0 months before pregnancy) and prenatal (between conception and birth) periods. Maternal bereavement was defined as death of a first-degree relative of the mother. Analyses were conducted using logistic and log-linear Poisson regressions that were adjusted for offspring, mother, and father sociodemographic and health factors.

RESULTS

We identified 6541 (0.004%) neonates, 3538 (0.002%) postneonates, and 2132 (0.001%) children between the ages of 1 and 5 years who died. After adjusting for covariates, bereavement during the preconception period was associated with increased odds of neonatal (adjusted odds ratio = 1.87, 95% confidence interval = 1.53-2.30) and postneonatal infant mortality (adjusted odds ratio = 1.52, 95% confidence interval = 1.15-2.02). Associations were timing specific (6 months before pregnancy only) and consistent across sensitivity analyses. Bereavement during the prenatal period was not consistently associated with increased risk of offspring mortality; however, this may reflect relatively low statistical power.

CONCLUSIONS

Results support and extend previous findings linking bereavement during the preconception period with increased odds of early offspring mortality. The period immediately before pregnancy may be a sensitive period with potential etiological implications and ramifications for offspring mortality.

Interpregnancy care

The aim of interconception care is to provide women who have had a prior adverse pregnancy outcome with optimal care in order to reduce risks that may affect the woman׳s health and any future birth she may choose to have. National recommendations call for action, and evidence supports specific clinical interventions. The need for interconception care is documented in national and state survey and surveillance data. Chronic diseases and behavioral risks affect the health of millions of U.S. women of childbearing age. Interconception care demonstration projects have used a "disease management" approach that includes medical care and case management. The increasing use of postpartum visits, as a gateway to interconception interventions, is essential. The Affordable Care Act emphasis on preventive services and expanded health coverage for women offers new opportunities to finance interconception care. Improved and enhanced clinical practices, along with the engagement of women, in interconception care have the potential to improve birth outcomes and reduce disparities.
