Two decades of interventions in New York State to reduce maternal mortality: a systematic review

United States Doula Programs and Their Outcomes: A Scoping Review to Inform State-Level Policies

BACKGROUND

The field of maternal health has advanced significantly over the past decades. However, the United States continues to have poor outcomes in comparison with other industrialized nations. With emerging evidence on the promise of doula care, states are including doula care under their Medicaid programs.

METHODS

We conducted a scoping review across four academic databases and gray literature published between January 1, 2012, and March 10, 2022, to describe the landscape of literature on U.S. doula programs and their outcomes in order to inform state policy makers considering laws or programs related to doula care.

FINDINGS

Of 740 records identified, 100 met inclusion criteria. Outcomes fell into four areas: birthing people's outcomes, infant outcomes, systems of care and implementation, and cross-cutting issues. Data on outcomes related to doula care in the literature were predominantly clinical, even though doulas are not clinical providers. Although some studies have found associations between doula care and improved clinical outcomes for birthing people and infants, the evidence is limited due to small sample sizes, study methodology, or conflicting conclusions. Doula outcomes are underexplored in the literature, with mainly qualitative data describing low levels of diversity and equity within the doula workforce and ineffective payment models. When cost-effectiveness estimates have been calculated, they largely rely on savings realized from averted cesarean births, preterm births, and neonatal intensive care unit admissions.

CONCLUSIONS

As state Medicaid programs expand to include doula care, policymakers should be aware of the limitations in the evidence as they plan for successful implementation, such as the narrow focus on certain clinical outcomes to quantify cost savings and conflicting conclusions on the impact of doula care. An important consideration is the impact of the reimbursement rate on the adoption of doula care, which is why it is important to engage doulas in compensation determinations, as well as the development of improved metrics to untangle the components that contribute to maternal health outcomes in the United States.

A Qualitative Study of Hospitals and Payers Implementing Community Doula Support

INTRODUCTION

The impact of doula care on birth outcomes is well-established; however, doula support remains underutilized. Identifying barriers and facilitators to implementation is integral as the demand for doula care increases. The primary objective of this study was to examine doula program implementation across hospitals and payers at varying stages of implementation.

METHODS

Representatives from 4 hospitals and 2 payers participated in focus group discussions. The doula programs were categorized as anticipated, initial, and advanced implementation statuses. Coding and thematic analysis were conducted using a deductive application of the Consolidated Framework for Implementation Research.

RESULTS

There were 20 participants across 5 focus group discussions. Participants were mostly female, and nearly all had worked at their organization for at least 2 years. Salient themes shared across participants included valuing internal outcome data or peer-reviewed literature to support doula care as well as anecdotal stories; the reality of the resource-intensive nature of doula care implementation that goes beyond funding for doulas; and both the need for individual champions for change, such as midwives, and a supportive organizational culture that values health equity.

DISCUSSION

The findings of this study highlight 3 contextual aspects that should be considered when implementing doula programs. These recommendations include: (1) use of a combination of research evidence and anecdotes when eliciting stakeholder support; (2) consideration of resources beyond funding such as program implementation support; (3) critical evaluation of organizational culture as a primary driver influencing the implementation of doula care. The future of the doula workforce in United States hospitals rests on the crux of intentional buy-in from hospital administration and clinical providers as well as the availability of requisite resources.

EngagINg the COmmunity to Reduce Preterm birth via Adherence To an Individualized Prematurity Prevention Plan (INCORPorATe IP3): intervention development and future pilot study design

OBJECTIVE

Non-Hispanic Black birthing individuals are at increased risk of preterm birth compared to other racial and ethnic groups. In our clinical setting, we offer a tailored package of recommendations to reduce the risk of preterm birth known as an individualized prematurity prevention plan (IP3). Patient-centered, community engaged interventions that address patient-perceived barriers to preterm birth prevention are urgently needed.

MATERIALS AND METHODS

We engaged a group of stakeholders to develop a mutli-level (patient-centered and community-involved) intervention that will increase adherence to an individualized prematurity prevention plan (IP3) by addressing barriers identified during our prior qualitative studies.

RESULTS

The intervention includes trained doulas from a community-led, Black owned doula group. The doulas will moderate group prenatal social support sessions. In between the group sessions, participants will be encouraged to continue interacting with one another and the doulas using a private Facebook™ group page. We will pilot test the intervention in a cohort of pregnant, self-identified non-Hispanic Black patients with a history of prior preterm birth.

CONCLUSION

We present a novel, patient-centered, community engaged intervention to reduce preterm birth in high-risk non-Hispanic Black birthing individuals. If the intervention is feasible based on the pilot study findings, we anticipate conducting an appropriately powered study to determine whether the intervention achieves our goal of reducing preterm birth.

Air pollution, children's academic achievement and the potential mediating role of preterm birth

INTRODUCTION

Previous research has observed relationships between higher prenatal exposure to air pollutants and neurodevelopmental and academic outcomes later in childhood. Identifying intermediate outcomes mediating this relationship would inform prevention and intervention efforts. We aimed to investigate if previously observed associations between prenatal exposure to common urban air pollutants, diesel and perchloroethylene, and performance on third grade standardized tests were mediated through increased risk of preterm birth.

METHODS

Data from the 1994-1998 birth cohorts within the New York City Longitudinal Study of Early Development were included in this analysis. Exposure was determined by linking the mother's residence at the time of delivery to the U.S. EPA's 1996 National Air Toxic Assessment of estimated ambient concentrations of diesel and perchloroethylene. Children's third grade standardized math and language tests were used as the markers for academic achievement. Missing data on covariates were imputed, while participants with missing information on gestational age and test scores were excluded. Linear regression models and causal mediation analysis were used to examine potential mediation by preterm birth.

RESULTS

In total, 187,723 and 196,122 participants were included in language and math analyses, respectively. Children with exposure to the fourth quartile of diesel or perchloroethylene had approximately 0.03 (95%CI: 0.02, 0.04) lower math z-scores when compared to individuals with exposure in the first quartile, although there was no consistent decreasing trend in math z-scores over increasing quartiles of diesel or perchloroethylene. We did not find evidence of mediation by preterm birth or exposure-mediator interaction in our models.

CONCLUSION

We did not find evidence that observed relationships between exposure to common urban air pollutants and test z-scores in childhood were mediated through an increased risk of preterm birth. This suggests other pathways between early exposure to air pollution and neurodevelopment should be investigated with causal mediation approaches.

A Community Collaborative for the Exploration of Local Factors Affecting Black Mothers' Experiences with Perinatal Care

Objectives

Black women face disparities in maternal morbidity and mortality when compared to White women. Multiple factors contribute to these disparities. This study examines the perspectives of Black women who have given birth in the last 5 years, to understand their pregnancy and birth experiences as a means of ascertaining factors that may be contributing to these disparities.

Methods

The Consortium to End Black Maternal Mortality was established as a collaborative table of cross-sector stakeholders and Black mothers to effectively conduct community-based participatory research focused on Black maternal health. Between January and March 2020, Black mothers who had given birth in the last 5 years facilitated Listening Sessions (LS) with other Black mothers in Rochester, NY. Participants reported on details of their pregnancy and delivery, including interaction with providers, personal relationships and their individual experience. The qualitative data captured during these sessions were coded to draw out key themes which were validated with LS participants and the Consortium.

Results

The key themes that emerged clustered into four groups, including: (1) Mother-Provider Communication; (2) Social Support; (3) Systemic factors and (4) Maternal Emotional & Mental Health. Mother-provider communication was the most salient factor affecting the maternal experience and was found to be influenced primarily by maternal health literacy and provider discriminatory attitudes and behaviors.

Conclusions for Practice

As a result of the Listening Sessions conducted with Black women, we identified mother-provider communication as the most important factor influencing the maternal experience.
