Group prenatal care and perinatal outcomes: a randomized controlled trial

The Role of Race in Pregnancy, Hypertension, and Long-Term Outcomes

PURPOSE OF REVIEW

This review aims to discuss racial and ethnic differences in the prevalence of hypertensive disorders of pregnancy (HDP), disparities in peripartum and postpartum outcomes, and strategies to improve health equity.

RECENT FINDINGS

Racial disparities in HDP are significant contributors to maternal morbidity and mortality. The prevalence of preeclampsia has increased over the last 20 years, with the highest prevalence among non-Hispanic Black, non-Hispanic American Indian and Alaska Native individuals. Black birthing individuals are at increased risk for cardiovascular-related morbidity and mortality, particularly from complications of HDP. Factors such as social determinants of health and systemic racism have a significant impact on disparities in maternal and fetal outcomes related to HDP. System changes and provider implicit bias training can help address systemic racism. Interventions aimed at improving access to care, such as telehealth and home blood pressure monitoring, as well as incorporating health system navigators that provide peripartum and postpartum support can improve outcomes and promote health equity.

Reproductive Justice Interventions in Pregnancy: Moving Toward Improving Black Maternal Perinatal and Intergenerational Mental Health Outcomes

LEARNING OBJECTIVE

After participating in this CME activity, the psychiatrist should be better able to:• Discuss the effects of structural racism on pregnancy and obstetric care and their contributions to maternal mental health challenges and inequitable outcomes.• Outline the current understanding of interventions initiated during pregnancy or childbirth that use reproductive justice principles to improve Black maternal perinatal and intergenerational mental health outcomes.

BACKGROUND

There are significant racial disparities in maternal outcomes for Black compared to White birthing people in the United States (US). Maternal mental health problems negatively affect mothers and their infants. Effects of structural racism during pregnancy and obstetric care may contribute to inequitable maternal mental health challenges and negative offspring outcomes. A reproductive justice framework provides a path for addressing these inequities. This systematic review examines whether pregnancy care interventions driven by reproductive justice principles have successfully improved Black maternal perinatal and intergenerational mental health outcomes.

METHODS

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for studies identified in November 2024 in PubMed, PsycInfo, and CINAHL. The studies included randomized clinical trials of Black birthing parents in the US and their offspring. Interventions incorporating reproductive justice principles were defined as those explicitly designed to increase autonomy, community input, racial equity, and/or cultural relevance.

RESULTS

The search revealed 619 unique records. After screening and full-text review, 12 studies were included. Of these, 7 studies reported statistically significant effects on mental health outcomes. The interventions included interpersonal therapy, culturally tailored cognitive behavioral therapy, group prenatal care, community health worker home visits, and an educational online platform. Six studies reported positive effects on maternal mental health outcomes (e.g., depressive symptoms or anxiety). One study reported positive infant mental health or developmental effects.

CONCLUSIONS

The effects of reproductive justice-driven interventions on Black maternal and offspring mental health outcomes are promising, but studies are limited. Future studies should further identify active intervention components and assess mental health-related outcomes in both generations to improve the mental health of Black mothers and prevent negative intergenerational effects.

Innovating Diabetes Care in Pregnancy: Do Group Care Models Improve Outcomes and Equity? A Report on Research Supported by Pathway to Stop Diabetes

Shared medical appointments (SMAs) for diabetes and group prenatal care (GPC) for pregnant patients have emerged as innovative care delivery models. They have the potential to transform diabetes care by overcoming many of the time limitations of traditional one-on-one clinical visits. There is compelling evidence that SMAs improve glycemic control for nonpregnant patients with diabetes, GPC reduces Black and White health disparities in preterm birth, and diabetes GPC increases postpartum glucose tolerance test uptake among patients with gestational diabetes mellitus. GPC models stand out as one of few interventions that reduce racial health disparities, which we hypothesize occurs because their effect is inadvertently exerted on both the patient and clinician through an over 20-h meaningful shared experience. In this article I explore the evidence for SMAs and GPC in diabetes and pregnancy, theoretical underpinnings of the models, their potential to promote more equitable care, and future directions from my perspective as a physician in high-risk obstetrics and 2019 American Diabetes Association Pathway Accelerator Award recipient. This article is part of a series of perspectives that report on research funded by the American Diabetes Association Pathway to Stop Diabetes program.

Identifying anticipated challenges when implementing group care: Context-analyses across seven countries to develop an anticipated challenges framework

PROBLEM

Despite increasing interest in Group Care worldwide, implementation is challenging.

BACKGROUND

Group Care is an evidence-based perinatal care model including three core components: health assessment, interactive learning, and community building. It has several advantages for service users and providers compared to individual perinatal care.

AIM

We aimed to identify anticipated challenges when implementing Group Care, and to develop a supporting tool based on these challenges.

METHODS

Context analyses through Rapid Qualitative Inquiries were conducted in 26 sites in seven countries to gain insight into the anticipated challenges when implementing Group Care. Data triangulation and investigator triangulation were applied. The context analyses generated 330 semi-structured interviews with service users and other stakeholders, 10 focus group discussions, and 56 review meetings with the research teams.

FINDINGS

We identified six surface structure anticipated challenges categories (content, materials, facilitators, timing, location, group composition), and five deep structure anticipated challenges categories (health assessment, scheduling Group Care into regular care, enrolment, (possible) partner organisations, financials) occurring in all participating sites, leading to the development of the Anticipated Challenges Framework.

CONCLUSION

Completing the Anticipated Challenges Framework raises awareness of anticipated challenges if sustainable Group Care implementation is to succeed and encourages the initiation of a concrete action plan to tackle these challenges. Application of the framework may offer important insights to health systems administrators and other key stakeholders before implementing Group Care. In the medium- and long-term, insights gained may lead to greater possibilities for sustainability and to the most cost-effective approaches for implementing Group Care.

Adherence to recommended prenatal visit schedules and risk for stillbirth, according to probable cause of death

OBJECTIVE

Suboptimal prenatal care is linked to increased risk of stillbirth, but this association is not well-understood. The study objective was to evaluate the relationship between prenatal visit adherence and cause of death in stillbirths.

STUDY DESIGN

This is a secondary analysis from the Stillbirth Collaborative Research Network of data with complete cause of death evaluation. Appropriateness of prenatal visit frequency was determined per American College of Obstetricians and Gynecologists/American Academy of Pediatrics (ACOG/AAP) recommendations and the novel Michigan Plan for Appropriately Tailored Healthcare in Pregnancy (MiPATH) guidelines. Multivariate regression controlled for differences between groups.

RESULTS

Among 451 stillbirths included, 63.6% and 55.9% were non-adherent to ACOG/AAP and MiPATH recommendations, respectively. Non-adherent parturients according to the Michigan plan were more likely to have a stillbirth due to hypertensive disorders of pregnancy.

CONCLUSION

Non-adherence to prenatal visit guidelines is associated with higher risk of stillbirth due to hypertensive disorders of pregnancy.

Enhancing Prenatal Group Medical Visits with Mindfulness Skills: A Pragmatic Trial with Latina and BIPOC Pregnant Women Experiencing Multiple Forms of Structural Inequity

Objectives

Prenatal mindfulness programs can improve mental health, yet access to and cultural and linguistic relevance of existing programs in the United States are limited for people who do not speak English and/or face major life stressors such as migration, housing instability, limited income, and racism. In response, mindfulness skills training drawn from Mindfulness-Based Childbirth and Parenting (MBCP) was integrated into Medicaid-covered CenteringPregnancy (CP) group prenatal healthcare, delivered in Spanish and English by certified nurse-midwives and community co-leaders, and tested in a pragmatic pilot trial.

Method

A provider survey of 17 CP clinics informed development of the enhanced program. Next, it was tested with 49 pregnant people who chose CP prenatal care. All of the sample identified as women; 4% as LGBTQ +; 90% as Black, Indigenous, and People of Color (65% as Latina/e/x); 10% as White; and 63% as Spanish-speaking. Groups were allocated 1:1 to CenteringPregnancy or CenteringPregnancy with Mindfulness Skills (CP +).

Results

Intent-to-treat analysis of self-report interview data indicated CP + yielded lower postpartum depression (the a priori primary study outcome) with a large effect size (Cohen's d = 0.80) and a trend toward lower postpartum anxiety (Cohen's d = 0.59) compared to CP. Hypothesized effects on mindfulness, positive/negative affect, and perceived stress were only partially supported at post-birth follow-up. Satisfaction with care was high across conditions.

Conclusions

Augmenting group prenatal healthcare with mindfulness training in Spanish and English appears feasible, did not reduce satisfaction with care, and may have additional mental health benefits. Key questions remain about structural supports for perinatal well-being.

Reflections on resilience

Resilience research has long sought to understand how factors at the child, family, school, community, and societal levels shape adaptation in the face of adversities such as poverty and war. In this article we reflect on three themes that may prove to be useful for future resilience research. First is the idea that mental and physical health can sometimes diverge, even in response to the same social process. A better understanding of explanations for this divergence will have both theoretical and public health implications when it comes to efforts to promote resilience. Second is that more recent models of stress suggest that stress can accelerate aging. Thus, we suggest that research on resilience may need to also consider how resilience strategies may need to be developed in an accelerated fashion to be effective. Third, we suggest that if psychological resilience interventions can be conducted in conjunction with efforts to enact system-level changes targeted at adversities, this may synergize the impact that any single intervention can have, creating a more coordinated and effective set of approaches for promoting resilience in young people who confront adversity in life.

The impact of group antenatal care on newborns: Results of a cluster randomized control trial in Eastern Region, Ghana

BACKGROUND

Maternal recognition of neonatal danger signs following birth is a strong predictor of care-seeking for newborn illness, which increases the odds of newborn survival. However, research suggests that maternal knowledge of newborn danger signs is low. Similarly, maternal knowledge of optimal newborn care practices has also been shown to be low. Since both issues are typically addressed during antenatal care, this study sought to determine whether group antenatal care (G-ANC) could lead to improvements in maternal recognition of danger signs and knowledge of healthy newborn practices, as well as boosting postnatal care utilization.

METHODS

This cluster randomized controlled trial of G-ANC compared to routine individual antenatal care (I-ANC) was conducted at 14 health facilities in Ghana, West Africa, from July 2019 to July 2023. Facilities were randomized to intervention or control, and pregnant participants at each facility were recruited into groups and followed for the duration of their pregnancies. 1761 participants were recruited: 877 into G-ANC; 884 into I-ANC. Data collection occurred at enrollment (T0), 34 weeks' gestation to 3 weeks postdelivery (T1) and 6-12 weeks postpartum (T2). Comparisons were made across groups and over time using logistic regression adjusted for clustering.

RESULTS

Overall, knowledge of newborn danger signs was significantly higher for women in G-ANC, both in aggregate (13-point scale) and for many of the individual items over time. Likewise, knowledge of what is needed to keep a newborn healthy was higher among women in G-ANC compared to I-ANC over time for the aggregate (7-point scale) and for many of the individual items. Women in G-ANC were less likely to report postnatal visits for themselves and their babies within 2 days of delivery than women in I-ANC, and there was no difference between groups regarding postnatal visits at one week or 6 weeks after birth.

CONCLUSION

This study illustrates that group ANC significantly improves knowledge of newborn danger signs and healthy newborn practices when compared to routine care, suggesting that the impact of G-ANC extends beyond impacts on maternal health. Further research elucidating care pathways for ill newborns and maternal behaviors around healthy newborn practices is warranted.

Diabetes Group Prenatal Care: A Systematic Review and Meta-analysis

OBJECTIVE

To estimate the effect of diabetes group prenatal care on rates of preterm birth and large for gestational age (LGA) among patients with diabetes in pregnancy compared with individual diabetes prenatal care.

DATA SOURCES

We searched Ovid Medline (1946-), Embase.com (1947-), Scopus (1823-), Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov .

METHODS OF STUDY SELECTION

We searched electronic databases for randomized controlled trials (RCTs) and observational studies comparing diabetes group prenatal care with individual care among patients with type 2 diabetes mellitus or gestational diabetes mellitus (GDM). The primary outcomes were preterm birth before 37 weeks of gestation and LGA (birth weight at or above the 90th percentile). Secondary outcomes were small for gestational age, cesarean delivery, neonatal hypoglycemia, neonatal intensive care unit admission, breastfeeding at hospital discharge, long-acting reversible contraception (LARC) uptake, and 6-week postpartum visit attendance. Secondary outcomes, limited to the subgroup of patients with GDM, included rates of GDM requiring diabetes medication (A2GDM) and completion of postpartum oral glucose tolerance testing (OGTT). Heterogeneity was assessed with the Cochran Q test and I2 statistic. Random-effects models were used to calculate pooled relative risks (RRs) and weighted mean differences.

TABULATION, INTEGRATION, AND RESULTS

Eight studies met study criteria and were included in the final analysis: three RCTs and five observational studies. A total of 1,701 patients were included in the pooled studies: 770 (45.3%) in diabetes group prenatal care and 931 (54.7%) in individual care. Patients in diabetes group prenatal care had similar rates of preterm birth compared with patients in individual care (seven studies: pooled rates 9.5% diabetes group prenatal care vs 11.5% individual care, pooled RR 0.77, 95% CI, 0.59-1.01), which held for RCTs and observational studies. There was no difference between diabetes group prenatal care and individual care in rates of LGA overall (four studies: pooled rate 16.7% diabetes group prenatal care vs 20.2% individual care, pooled RR 0.93, 95% CI, 0.59-1.45) or by study type. Rates of other secondary outcomes were similar between diabetes group prenatal care and individual care, except patients in diabetes group prenatal care were more likely to receive postpartum LARC (three studies: pooled rates 46.1% diabetes group prenatal care vs 34.1% individual care, pooled RR 1.44, 95% CI, 1.09-1.91). When analysis was limited to patients with GDM, there were no differences in rates of A2GDM or postpartum visit attendance, but patients in diabetes group prenatal care were significantly more likely to complete postpartum OGTT (five studies: pooled rate 74.0% diabetes group prenatal care vs 49.4% individual care, pooled RR 1.58, 95% CI, 1.19-2.09).

CONCLUSION

Patients with type 2 diabetes and GDM who participate in diabetes group prenatal care have similar rates of preterm birth, LGA, and other pregnancy outcomes compared with those who participate in individual care; however, they are significantly more likely to receive postpartum LARC, and those with GDM are more likely to return for postpartum OGTT.

Interventions to mitigate pregnancy-related mortality and morbidity in Black birthing people: a systematic review

OBJECTIVE

To conduct a systematic review of interventions to improve perinatal outcomes to mitigate pregnancy-related mortality and morbidity in Black birthing people.

DATA SOURCES

We searched 5 databases from 2000 through the final search date of April 5, 2023: Cumulative Index of Nursing and Allied Health Literature Plus with Full Text (EBSCOhost), Embase (Elsevier), PubMed, and Scopus (Elsevier) and ClinicalTrials.gov.

STUDY ELIGIBILITY CRITERIA

Only quantitative studies were eligible including observational and randomized controlled trials. All participants in selected studies must identify as Black or study results must be stratified by race that includes Black birthing people. The study must (1) measure a perinatal outcome of interest (2) occur in the United States and (3) be written in the English language. Studies were excluded if they were published prior to 2000, not published in the English language, or did not meet the criteria above.

STUDY APPRAISAL AND SYNTHESIS METHODS

A data extraction template identified intervention type and perinatal outcome. Perinatal outcomes included but were not limited to: cardiovascular disorders, mortality, or preterm delivery. Interventions included: community programs, educational enhancement, individual counseling, medical intervention, or policy. Risk of bias was assessed using the Mixed Method Appraisal Tool. Three investigators assessed studies individually and group consensus was used for a final decision.

RESULTS

From 4,302 unique studies, 41 studies met inclusion criteria. Community programs such as the Supplemental Program for Women, Infants, and Children (WIC) and Healthy Start (n=17, 41.5%) were the most common interventions studied. Individual counseling closely followed (n=15, 36.6%). Medical interventions were not among the more commonly used intervention types (n=9, 21.9%). Most articles focused on preterm delivery (n=28, 68.3%). Few articles studied cardiovascular disorders (n=4, 9.8%) or hemorrhage (n=3, 7.3%). No articles studied pregnancy-related morbidity.

CONCLUSIONS

Despite current conversations on Black maternal mortality, there is currently limited literature examining interventions addressing perinatal morbidity and mortality in Black birthing people in the United States. These interventions do not address how to mitigate perinatal outcomes of interest. Patient-centered outcomes research is warranted to better understand as well as to resolve inequities related to Black maternal health. El resumen está disponible en Español al final del artículo.

What are the mechanisms of effect of group antenatal care? A systematic realist review and synthesis of the literature

BACKGROUND

There is growing interest in the benefits of group models of antenatal care. Although clinical reviews exist, there have been few reviews that focus on the mechanisms of effect of this model.

METHODS

We conducted a realist review using a systematic approach incorporating all data types (including non-research and audiovisual media), with synthesis along Context-Intervention-Mechanism-Outcome (CIMO) configurations.

RESULTS

A wide range of sources were identified, yielding 100 relevant sources in total (89 written and 11 audiovisual). Overall, there was no clear pattern of 'what works for whom, in what circumstances' although some studies have identified clinical benefits for those with more vulnerability or who are typically underserved by standard care. Findings revealed six interlinking mechanisms, including: social support, peer learning, active participation in health, health education and satisfaction or engagement with care. A further, relatively under-developed theory related to impact on professional practice. An overarching mechanism of empowerment featured across most studies but there was variation in how this was collectively or individually conceptualised and applied.

CONCLUSIONS

Mechanisms of effect are amplified in contexts where inequalities in access and delivery of care exist, but poor reporting of populations and contexts limited fuller exploration. We recommend future studies provide detailed descriptions of the population groups involved and that they give full consideration to theoretical underpinnings and contextual factors.

REGISTRATION

The protocol for this realist review was registered in the International Prospective Register of Systematic Reviews (PROSPERO CRD42016036768).

Comparing Group Versus Individual Prenatal Care on Breastfeeding Practice and Motivational Factors

OBJECTIVE

Although breastfeeding in the first 6 months postpartum benefits both infants and mothers, breastfeeding rates remain low. This study examined whether group prenatal care was associated with an increased breastfeeding initiation and duration compared with those receiving usual, individual prenatal care. A secondary aim was to investigate whether sociodemographic and motivational factors were associated with breastfeeding initiation and duration across prenatal care groups.

METHODS

Pregnant women in their third trimester ( n = 211) from an innercity university medical center participated. Prenatal care type was identified from the medical chart, and data on breastfeeding duration at 1, 3, and 6 months postpartum were collected. Breastfeeding motivational factors were assessed with a survey. Logistic regressions and independent-samples t tests were used for data analyses.

RESULTS

After controlling for demographic factors, group prenatal care was associated with increased breastfeeding at 6 months postpartum (odds ratio = 2.66; P = .045) compared with individual care. Breastfeeding intention ( P < .001), competence ( P = .003), and autonomous motivation ( P < .001) were significantly higher, while amotivation ( P = .034) was significantly lower in group compared with individual prenatal care.

CONCLUSIONS

Breastfeeding persistence was higher among women receiving group prenatal care, potentially due to motivational factors. Future studies should investigate how breastfeeding motivational factors could be effectively targeted in prenatal care to increase breastfeeding persistence.

A group prenatal care intervention reduces gestational weight gain and gestational diabetes in American Samoan women

OBJECTIVE

The objective of this study was to determine the preliminary effectiveness of an intervention to mitigate adverse pregnancy outcomes associated with pre-pregnancy obesity in American Samoa.

METHODS

We enrolled n = 80 low-risk pregnant women at <14 weeks' gestation. A complete case analysis was conducted with randomized group assignment (group prenatal care-delivered intervention vs. one-on-one usual care) as the independent variable. Primary outcomes were gestational weight gain and postpartum weight change. Secondary outcomes included gestational diabetes screening and exclusive breastfeeding at 6 weeks post partum. Other outcomes reported include gestational diabetes incidence, preterm birth, mode of birth, infant birth weight, and macrosomia.

RESULTS

Gestational weight gain was lower among group versus usual care participants (mean [SD], 9.46 [7.24] kg vs. 14.40 [8.23] kg; p = 0.10); postpartum weight change did not differ between groups. Although the proportion of women who received adequate gestational diabetes screening (78.4% group; 65.6% usual care) was similar, there were clinically important between-group differences in exclusive breastfeeding (44.4% group; 25% usual care), incidence of gestational diabetes (27.3% group; 40.0% usual care), and macrosomia (8.3% group; 29.0% usual care).

CONCLUSIONS

It may be possible to address multiple risk factors related to intergenerational transmission of obesity in this high-risk setting using a group care-delivered intervention.

Examining Black Birthing People's Experiences with Racism, Discrimination, and Contextualized Stress and Their Perspectives on Racial Concordance with Prenatal Providers

Introduction

We examine Black birthing people's experiences with racism, discrimination, and contextualized stress and whether those experiences are associated with preference for racially concordant prenatal care providers.

Methods

This cross-sectional study is the quantitative component of a larger, mixed-methods study. Data were from initial (August-October 2021) and follow-up (December 2022-January 2023) surveys among self-identified Black and/or African American birthing people who delivered a baby at a university system between 2019 and 2021 and were at least 18 years old. Respondents were 3-32 months postdelivery at the initial survey, which collected data on demographics and the Perceived Racism (ranges 0-430), Perceived Discrimination (ranges 0-36), and Jackson, Hogue, Phillips Contextualized Stress Measure (ranges 0-355) scales. The follow-up survey assessed views on racial and gender concordance and continuity with prenatal providers. Pearson correlation coefficients assessed relationships between scale scores and agreement that racial concordance is important and preferable. Poisson regression assessed whether a top quartile score on scales was related to importance of and preference for racial concordance with providers.

Results

Participants (n = 200) scored medians of 99.5 on the racism scale, 33 on the discrimination scale, and 177 on the contextualized stress scale. Of follow-up survey participants (n = 69), 78.3% agreed they would choose a racially concordant prenatal provider if possible (n = 54) and 42.0% agreed that racial concordance with their provider was important (n = 29). Scoring higher on discrimination and contextualized stress scales was positively correlated with agreeing that racial concordance was important. Regression analyses showed no significant associations between scale scores and agreeing that racial concordance with one's prenatal provider is important or preferable.

Conclusion

Black birthing people experience high levels of racism, discrimination, and contextualized stress. The overwhelming majority would choose racial concordance with their prenatal provider if possible.

Patient-Provider Satisfaction and Communication in U.S. Prenatal Care: A Systematic Review

INTRODUCTION

This is a systematic review on patient-provider satisfaction in U.S. prenatal care by addressing the following research question: What factors influence patient-provider satisfaction during prenatal care?

METHODS

Thirty six online databases were searched for peer-reviewed research from February to September of 2018 using 10 key terms published in English on U.S. populations between the years 1993-2018 on the topic of provider communication skills and patient satisfaction in the prenatal context. Searches yielded 2563 articles. After duplicates were reviewed and eligibility determined, 32 articles met criteria and were included in the final content analysis. All reported study variables were entered into EXCEL, data reported in each study were analyzed by two people for inter-rater reliability and included in the qualitative content analysis. Two researchers also utilized assessment tools to assess the quality of the articles.

RESULTS

Results indicate the importance of good patient-provider communication, that patients have a need for more information on a plethora of topics, and that Hispanic and African American women reported less satisfaction.

DISCUSSION

We recommend that future studies measure potentially significant themes not adequately present in the reviewed studies such as practitioner demographics (e.g. gender, years of experience, or race/ethnicity), mothers under 18 years of age, inclusion of religious minorities, patients with differing immigration statuses, and patients with disabilities.

FIGO good practice recommendations on optimizing models of care for the prevention and mitigation of preterm birth

The global challenge of preterm birth persists with little or no progress being made to reduce its prevalence or mitigate its consequences, especially in low-resource settings where health systems are less well developed. Improved delivery of respectful person-centered care employing effective care models delivered by skilled healthcare professionals is essential for addressing these needs. These FIGO good practice recommendations provide an overview of the evidence regarding the effectiveness of the various care models for preventing and managing preterm birth across global contexts. We also highlight that continuity of care within existing, context-appropriate care models (such as midwifery-led care and group care), in primary as well as secondary care, is pivotal to delivering high quality care across the pregnancy continuum-prior to conception, through pregnancy and birth, and preparation for a subsequent pregnancy-to improve care to prevent and manage preterm birth.

Implementing group care in Dutch and Surinamese maternity and child care services: the vital importance of addressing outer context barriers

BACKGROUND

By addressing physical and psychosocial needs, group care (GC) improves health-related behaviours, peer support, parent-provider interactions and may improve birth outcomes. Hence, global implementation of GC is encouraged. Context analyses prior to implementation are vital to elucidate which local factors may support or hinder implementation.

METHODS

Contextual analyses conducted in the Netherlands and Suriname were compared to identify the factors relevant to the implementability of GC as perceived by healthcare professionals (HCPs). 32 semi-structured interviews were conducted with Dutch and Surinamese healthcare professionals. Audio recordings were transcribed verbatim and coded using the Framework approach. The Consolidated Framework for Implementation Research guided the development of the interview guide and of the coding tree.

RESULTS

Outer setting: Concerns regarding funding surfaced in both countries. Due to limited health insurance coverage, additional fees would limit accessibility in Suriname. In the Netherlands, midwives dreaded lower revenue due to reimbursement policies that favour one-on-one care. Inner setting: Appropriate space for GC was absent in one Dutch and three Surinamese facilities. Role division regarding GC implementation was clearer in the Netherlands than in Suriname.

INNOVATION

HCPs from both countries expected increased social support, health knowledge among women, and continuity of care(r). Individuals/innovation deliverers: Self-efficacy and motivation emerged as intertwined determinants to GC implementation in both countries. Individuals/innovation recipients: Competing demands can potentially lower acceptability of GC in both countries. While Dutch HCPs prioritised an open dialogue with mothers, Surinamese HCPs encouraged the inclusion of partners.

PROCESS

Campaigns to raise awareness of GC were proposed. Language barriers were a concern for Dutch but not for Surinamese HCPs.

CONCLUSIONS

While the most striking differences between both countries were found in the outer setting, they trickle down and affect all layers of context. Ultimately, at a later stage, the process evaluation will show if those outer setting barriers we identified prior to implementation actually hindered GC implementation. Changes to the health care systems would ensure sustained implementation in both countries, and this conclusion feeds into a more general discussion: how to proceed when contextual analyses reveal barriers that cannot be addressed with the time and resources available.

Integrated group antenatal and pediatric care in Haiti: A comprehensive care accompaniment model

INTRODUCTION

The J9 Plus (J9) maternal-child accompaniment program is based on four pillars: group antenatal care (GANC), group pediatric care, psychosocial support, and community-based care. We aimed to evaluate the impact of the J9 model of care on perinatal outcomes.

METHODOLOGY

We conducted a convergent mixed methods study of maternal-newborn dyads born in 2019 at Hôpital Universitaire de Mirebalais. Quantitative data was collected retrospectively to compare dyads receiving J9 care to usual care. A secondary analysis of qualitative data described patient perspectives of J9 care.

RESULTS

Antenatal care attendance was significantly higher among women in J9 (n = 524) compared to usual care (n = 523), with 490(93%) and 189(36%) having >4 visits, respectively; p <0.001, as was post-partum visit attendance [271(52%) compared to 84(16%), p<0.001] and use of post-partum family planning methods [98(19%) compared to 47(9%), p = 0.003]. Incidence of pre-eclampsia with severe features was significantly lower in the J9 group [44(9%)] compared to the usual care group [73(14%)], p <0.001. Maternal and neonatal mortality and low birth weight did not differ across groups. Cesarean delivery [103(20%) and 82(16%), p<0.001] and preterm birth [118 (24%)] and 80 (17%), p <0.001] were higher in the J9 group compared to usual care, respectively. In the qualitative analysis, ease of access to high-quality care, meaningful social support, and maternal empowerment through education were identified as key contributors to these outcomes.

CONCLUSION

Compared to usual care, the J9 Plus maternal-child accompaniment model of care is associated with increased engagement in antenatal and postpartum care, increased utilization of post-partum family planning, and lower incidence of pre-eclampsia with severe features, which remains a leading cause of maternal mortality in Haiti. The J9 accompaniment approach to care is an empowering model that has the potential to be replicated in similar settings to improve quality of care and outcomes globally.

Codesign and refinement of an optimised antenatal education session to better inform women and prepare them for labour and birth

OBJECTIVE

Our objective was to codesign, implement, evaluate acceptability and refine an optimised antenatal education session to improve birth preparedness.

DESIGN

There were four distinct phases: codesign (focus groups and codesign workshops with parents and staff); implementation of intervention; evaluation (interviews, questionnaires, structured feedback forms) and systematic refinement.

SETTING

The study was set in a single maternity unit with approximately 5500 births annually.

PARTICIPANTS

Postnatal and antenatal women/birthing people and birth partners were invited to participate in the intervention, and midwives were invited to deliver it. Both groups participated in feedback.

OUTCOME MEASURES

We report on whether the optimised session is deliverable, acceptable, meets the needs of women/birthing people and partners, and explain how the intervention was refined with input from parents, clinicians and researchers.

RESULTS

The codesign was undertaken by 35 women, partners and clinicians. Five midwives were trained and delivered 19 antenatal education (ACE) sessions to 142 women and 94 partners. 121 women and 33 birth partners completed the feedback questionnaire. Women/birthing people (79%) and birth partners (82%) felt more prepared after the class with most participants finding the content very helpful or helpful. Women/birthing people perceived classes were more useful and engaging than their partners. Interviews with 21 parents, a midwife focus group and a structured feedback form resulted in 38 recommended changes: 22 by parents, 5 by midwives and 11 by both. Suggested changes have been incorporated in the training resources to achieve an optimised intervention.

CONCLUSIONS

Engaging stakeholders (women and staff) in codesigning an evidence-informed curriculum resulted in an antenatal class designed to improve preparedness for birth, including assisted birth, that is acceptable to women and their birthing partners, and has been refined to address feedback and is deliverable within National Health Service resource constraints. A nationally mandated antenatal education curriculum is needed to ensure parents receive high-quality antenatal education that targets birth preparedness.

Effects of Two Group Prenatal Care Interventions on Mental Health: An RCT

INTRODUCTION

Perinatal depression and anxiety cost the U.S. health system $102 million annually and result in adverse health outcomes. Research supports that cognitive behavioral therapy improves these conditions, but barriers to obtaining cognitive behavioral therapy have prevented its success in pregnant individuals. In this study, the impact of a cognitive behavioral therapy-based intervention on anxiety, depression, stress, healthy lifestyle beliefs, and behaviors in pregnant people was examined.

STUDY DESIGN

This study used a 2-arm RCT design, embedded in group prenatal care, with one arm receiving a cognitive behavioral therapy-based Creating Opportunities for Personal Empowerment program and the other receiving health promotion content.

SETTING/PARTICIPANTS

Black and Hispanic participants (n=299) receiving prenatal care from 2018 to 2022 in New York and Ohio who screened high on 1 of 3 mental health measures were eligible to participate.

INTERVENTION

Participants were randomized into the manualized Creating Opportunities for Personal Empowerment cognitive behavioral therapy-based program, with cognitive behavioral skill-building activities delivered by advanced practice nurses in the obstetrical setting.

MAIN OUTCOME MEASURES

Outcomes included anxiety, depression, and stress symptoms using valid and reliable tools (Generalized Anxiety Disorder scale, Edinburgh Postnatal Depression Scale, and Perceived Stress Scale). The Healthy Lifestyle Beliefs and Behaviors Scales examined beliefs about maintaining a healthy lifestyle and reported healthy behaviors.

RESULTS

There were no statistically significant differences between groups in anxiety, depression, stress, healthy beliefs, and behaviors. There were significant improvements in all measures over time. There were statistically significant decreases in anxiety, depression, and stress from baseline to intervention end, whereas healthy beliefs and behaviors significantly increased.

CONCLUSIONS

Both cognitive behavioral therapy and health promotion content embedded in group prenatal care with advanced practice nurse delivery improved mental health and healthy lifestyle beliefs and behaviors at a time when perinatal mood generally worsens.

Group Multimodal Prenatal Care and Postpartum Outcomes

Importance

An increasing body of evidence suggests equivalent if not improved postpartum outcomes of in-person group prenatal care compared with individual prenatal care. However, research is needed to evaluate outcomes of group multimodal prenatal care (GMPC), with groups delivered virtually in combination with individual in-person office appointments to collect vital signs and conduct other tests compared with individual multimodal prenatal care (IMPC) delivered through a combination of remotely delivered and in-person visits.

Objective

To compare postpartum outcomes between GMPC and IMPC.

Design, Setting, and Participants

A frequency-matched longitudinal cohort study was conducted at Kaiser Permanente Northern California, an integrated health care delivery system. Participants included 424 individuals who were pregnant (212 GMPC and 212 frequency-matched IMPC controls (matched on gestational age, race and ethnicity, insurance status, and maternal age) receiving prenatal care between August 17, 2020, and April 1, 2021. Participants completed a baseline survey before 14 weeks' gestation and a follow-up survey between 4 and 8 weeks post partum. Data analysis was performed from January 3, 2022, to March 4, 2024.

Exposure

GMPC vs IMPC.

Main Outcome Measures

Validated instruments were used to ascertain postpartum psychosocial outcomes (stress, depression, anxiety) and perceived quality of prenatal care. Self-reported outcomes included behavioral outcomes (breastfeeding initiation, use of long-acting reversible contraception), satisfaction with prenatal care, and preparation for self and baby care after delivery. Primary analyses included all study participants in the final cohort. Three secondary dose-stratified analyses included individuals who attended at least 1 visit, 5 visits, and 70% of visits. Log-binomial regression and linear regression analyses were conducted.

Results

The final analytic cohort of 390 participants (95.6% follow-up rate of 408 singleton live births) was racially and ethnically diverse: 98 (25.1%) Asian/Pacific Islander, 88 (22.6%) Hispanic, 17 (4.4%) non-Hispanic Black, 161 (41.3%) non-Hispanic White, and 26 (6.7%) multiracial participants; median age was 32 (IQR, 30-35) years. In the primary analysis, after adjustment, GMPC was associated with a 21% decreased risk of perceived stress (adjusted risk ratio [ARR], 0.79; 95% CI, 0.67-0.94) compared with IMPC. Findings were consistent in the dose-stratified analyses. There were no significant differences between GMPC and IMPC for other psychosocial outcomes. While in the primary analyses there was no significant group differences in perceived quality of prenatal care (mean difference [MD], 0.01; 95% CI, -0.12 to 0.15) and feeling prepared to take care of baby at home (ARR, 1.09; 95% CI, 0.96-1.23), the dose-stratified analyses documented higher perceived quality of prenatal care (MD, 0.16; 95% CI, 0.01-0.31) and preparation for taking care of baby at home (ARR, 1.27; 95% CI, 1.13-1.43) for GMPC among those attending 70% of visits. No significant differences were noted in patient overall satisfaction with prenatal care and feeling prepared for taking care of themselves after delivery.

Conclusions

In this cohort study, equivalent and, in some cases, better outcomes were observed for GMPC compared with IMPC. Health care systems implementing multimodal models of care may consider incorporating virtual group prenatal care as a prenatal care option for patients.

Association between mindful and practical eating skills and eating behaviors among racially diverse pregnant women in four selected clinical sites in the United States

Background: Mindful eating is a promising strategy to address problematic eating behaviors; however, little is known about its applicability during pregnancy. No studies have examined the combined effects of mindful and practical eating skills on eating behaviors. Aim: We examined associations between mindful and practical eating skills and eating behaviors (nutritional intake and emotional eating) among pregnant women who received psychoeducation on healthy eating and pregnancies. Methods: Participants were racially-diverse pregnant women (14-42 years) from four clinical sites in Detroit, Michigan, and Nashville, Tennessee (N = 741). We conducted multiple linear regression to examine associations between mindful (hunger cues, satiety cues, mindful check-ins) and practical (food diary/journal, MyPlate method) eating skills and nutritional intake. We calculated residualized change scores to represent changes in the quality of nutritional intake from second to third trimester. We performed multiple logistic regression to examine associations between mindful and practical eating skills and emotional eating. Results: Women improved over time in eating behaviors (better nutrition, less emotional eating). Regular use of MyPlate was associated with better nutritional intake (unstandardized coefficient [B] = -0.61), but food diaries were not. We found a significant interaction in predicting emotional eating: For those regularly paying attention to hunger cues, some use of MyPlate (Adjusted Odds Ratio [AOR] = 0.39) and especially regular use of MyPlate (AOR = 0.13) reduced the likelihood of emotional eating during pregnancy. Conclusion: Enhancing both mindful and practical eating skills, such as paying attention to hunger cues, and using the MyPlate method, may facilitate pregnant women's ability to improve their eating behaviors.

Barriers to implementing good nutrition in pregnancy and early childhood: Creating equitable national solutions

Exposure to deleterious stressors in early life, such as poor nutrition, underlies most adult-onset chronic diseases. As rates of chronic disease continue to climb in the United States, a focus on good nutrition before and during pregnancy, lactation, and early childhood provides a potential opportunity to reverse this trend. This report provides an overview of nutrition investigations in pregnancy and early childhood and addresses racial disparities and health outcomes, current national guidelines, and barriers to achieving adequate nutrition in pregnant individuals and children. Current national policies and community interventions to improve nutrition, as well as the current state of nutrition education among healthcare professionals and students, are discussed. Major gaps in knowledge and implementation of nutrition practices during pregnancy and early childhood were identified and action goals were constructed. The action goals are intended to guide the development and implementation of critical nutritional strategies that bridge these gaps. Such goals create a national blueprint for improving the health of mothers and children by promoting long-term developmental outcomes that improve the overall health of the US population.

Evaluating the relationship between conditional cash transfer programme on preterm births: a retrospective longitudinal study using the 100 million Brazilian cohort

BACKGROUND

Preterm births increase mortality and morbidity during childhood and later life, which is closely associated with poverty and the quality of prenatal care. Therefore, income redistribution and poverty reduction initiatives may be valuable in preventing this outcome. We assessed whether receipt of the Brazilian conditional cash transfer programme - Bolsa Familia Programme, the largest in the world - reduces the occurrence of preterm births, including their severity categories, and explored how this association differs according to prenatal care and the quality of Bolsa Familia Programme management.

METHODS

A retrospective cohort study was performed involving the first live singleton births to mothersenrolled in the 100 Million Brazilian Cohort from 2004 to 2015, who had at least one child before cohort enrollment. Only the first birth during the cohort period was included, but born from 2012 onward. A deterministic linkage with the Bolsa Familia Programme payroll dataset and a similarity linkage with the Brazilian Live Birth Information System were performed. The exposed group consisted of newborns to mothers who received Bolsa Familia from conception to delivery. Our outcomes were infants born with a gestational age < 37 weeks: (i) all preterm births, (ii) moderate-to-late (32-36), (iii) severe (28-31), and (iv) extreme (< 28) preterm births compared to at-term newborns. We combined propensity score-based methods and weighted logistic regressions to compare newborns to mothers who did and did not receive Bolsa Familia, controlling for socioeconomic conditions. We also estimated these effects separately, according to the adequacy of prenatal care and the index of quality of Bolsa Familia Programme management.

RESULTS

1,031,053 infants were analyzed; 65.9% of the mothers were beneficiaries. Bolsa Familia Programme was not associated with all sets of preterm births, moderate-to-late, and severe preterm births, but was associated with a reduction in extreme preterm births (weighted OR: 0.69; 95%CI: 0.63-0.76). This reduction can also be observed among mothers receiving adequate prenatal care (weighted OR: 0.66; 95%CI: 0.59-0.74) and living in better Bolsa Familia management municipalities (weighted OR: 0.56; 95%CI: 0.43-0.74).

CONCLUSIONS

An income transfer programme for pregnant women of low-socioeconomic status, conditional to attending prenatal care appointments, has been associated with a reduction in extremely preterm births. These programmes could be essential in achieving Sustainable Development Goals.

Group prenatal care successes, challenges, and frameworks for scaling up: a case study in adopting health care innovations

BACKGROUND

Group prenatal care enhances quality of care, improves outcomes, and lowers costs. However, this healthcare innovation is not widely available. Using a case-study approach, our objectives were to (1) examine organizational characteristics that support implementation of Expect With Me group prenatal care and (2) identify key factors influencing adoption and sustainability.

METHODS

We studied five clinical sites implementing group prenatal care, collecting qualitative data including focus group discussions with clinicians (n = 4 focus groups, 41 clinicians), key informant interviews (n = 9), and administrative data. We utilized a comparative qualitative case-study approach to characterize clinical sites and explain organizational traits that fostered implementation success. We characterized adopting and non-adopting (unable to sustain group prenatal care) sites in terms of fit for five criteria specified in the Framework for Transformational Change: (1) impetus to transform, (2) leadership commitment to quality, (3) improvement initiatives that engage staff, (4) alignment to achieve organization-wide goals, and (5) integration.

RESULTS

Two sites were classified as adopters and three as non-adopters based on duration, frequency, and consistency of group prenatal care implementation. Adopters had better fit with the five criteria for transformational change. Adopting organizations were more successful implementing group prenatal care due to alignment between organizational goals and resources, dedicated healthcare providers coordinating group care, space for group prenatal care sessions, and strong commitment from organization leadership.

CONCLUSIONS

Adopting sites were more likely to integrate group prenatal care when stakeholders achieved alignment across staff on organizational change goals, leadership buy-in, and committed institutional support and dedicated resources to sustain it.

Birth Outcomes for Medically High-Risk Pregnancies: Comparing Group to Individual Prenatal Care

OBJECTIVES

Group prenatal care models were initially designed for women with medically low-risk pregnancies, and early outcome data focused on these patient populations. Pregnancy outcome data for women with medically high-risk pregnancies participating in group prenatal care is needed to guide clinical practice. This study compares rates of preterm birth, low birth weight, and neonatal intensive care unit admissions among women with medical risk for poor birth outcomes who receive group versus individual prenatal care.

STUDY DESIGN

This retrospective cohort study uses vital statistics data to compare pregnancy outcomes for women from 21 obstetric practices participating in a statewide expansion project of group prenatal care. The study population for this paper included women with pregestational or gestational hypertension, pregestational or gestational diabetes, and high body mass index (BMI > 45 kg/m2). Patients were matched using propensity scoring, and outcomes were compared using logistic regression. Two levels of treatment exposure based on group visit attendance were evaluated for women in group care: any exposure (one or more groups) or minimum threshold (five or more groups).

RESULTS

Participation in group prenatal care at either treatment exposure level was associated with a lower risk of neonatal intensive care unit (NICU) admissions (10.2 group vs. 13.8% individual care, odds ratio [OR] = 0.708, p < 0.001). Participating in the minimum threshold of groups (five or more sessions) was associated with reduced risk of preterm birth (11.4% group vs. 18.4% individual care, OR = 0.569, p < 0.001) and NICU admissions (8.4% group vs. 15.9% individual care, OR = 0.483, p < 0.001). No differences in birth weight were observed.

CONCLUSION

This study provides preliminary evidence that women who have or develop common medical conditions during pregnancy are not at greater risk for preterm birth, low birth weight, or NICU admissions if they participate in group prenatal care. Practices who routinely exclude patients with these conditions from group participation should reconsider increasing inclusivity of their groups.

KEY POINTS

· This study compares outcomes for women who receive group versus individual prenatal care. · The study population was limited to women with diabetes, hypertension, and/or high BMI.. · Group participants did not have higher rates of preterm birth, low birth weight, or NICU admissions..

Group prenatal care for pregnant women with opioid use disorder: Preliminary evidence for acceptability and benefits compared with individual prenatal care

INTRODUCTION

The effectiveness of group prenatal care (G-PNC) compared with individual prenatal care (I-PNC) for women with opioid use disorder (OUD) is unknown. The objectives of this study were to (1) assess the acceptability of co-locating G-PNC at an opioid treatment program and (2) describe the maternal and infant characteristics and outcomes of pregnant women in treatment for OUD who participated in G-PNC and those who did not.

METHODS

This was a retrospective cohort study of 71 women (G-PNC n = 15; I-PNC n = 56) who were receiving treatment for OUD from one center and who delivered in 2019. Acceptability was determined by assessing the representativeness of the G-PNC cohorts, examining attendance at sessions, and using responses to a survey completed by G-PNC participants. The receipt of health services and healthcare use, behaviors, and infant health between those who participated in G-PNC and those who received I-PNC were described.

RESULTS

G-PNC was successfully implemented among women with varying backgrounds (e.g., racial, ethnic, marital status) who self-selected into the group. All G-PNC participants reported that they were satisfied to very satisfied with the program. Increased rates of breastfeeding initiation, breastfeeding at hospital discharge, receipt of the Tdap vaccine, and postpartum visit attendance at 1-2 weeks and 4-8 weeks were observed in the G-PNC group compared with the I-PNC group. Fewer G-PNC reported postpartum depression symptomatology.

CONCLUSION

Findings suggest that co-located G-PNC at an opioid treatment program is an acceptable model for pregnant women in treatment for OUD and may result in improved outcomes.

Evaluating the Impact of CenteringPregnancy Program Versus Individual Prenatal Care on Gestational Weight Gain

Introduction: The CenteringPregnancy (CP) program-proven to reduce preterm births-was modified to achieve more optimal gestational weight gain (GWG) by an intentional incorporation of nutrition education. We compared the effect of the modified CP program versus individual prenatal care (IPNC) on GWG. Methods: This observational study used linked birth certificate data and hospital discharge records of women who received prenatal care (PNC) in South Carolina Midlands' obstetric clinics between 2015 and 2019. Linear and multinomial logistic regressions were used to compare participants in CP (n = 568) versus IPNC on weight gain, measured by total GWG (delivery weight minus prepregnancy weight), weekly rate of weight gain, and meeting the Institute of Medicine's recommendations (inadequate, adequate, and excessive GWG). Nonrandom assignment to program was controlled by propensity scoring. Results: CP participants differed from IPNC participants in race, nulliparous, education, and type of health insurance, but not in parity or month PNC began (p-Value <0.05). CP and IPNC participants had a similar GWG experience: total GWG (coef(β) = -0.054; 95% confidence interval [CI] -0.78 to 0.6), total weekly weight gain (coef(β) = -0.004; 95% CI -0.03 to 0.03), total GWG category (inadequate GWG: RRR = 0.85, 95% CI 0.64-1.21, and excessive GWG: relative risk ratio (RRR) = 0.92, 95% CI 0.71-1.20 vs. adequate), and weekly weight gain category (inadequate GWG: RRR = 0.73, 95% CI 0.53-1.01, and excessive GWG: RRR = 0.83, 95% CI 0.61-1.13 vs. adequate). Conclusion: The CP program with an enhanced nutritional knowledge component was not associated with achieving recommended GWG. Further investigation is needed to explain the lack of impact.

The Effect of CenteringPregnancy Group Antenatal Care on Maternal, Birth, and Neonatal Outcomes Among Low-Risk Women in the Netherlands: A Stepped-Wedge Cluster Randomized Trial

INTRODUCTION

This study was carried out to assess the effects of participating in CenteringPregnancy (CP) on maternal, birth, and neonatal outcomes among low-risk pregnant women in the Netherlands.

METHODS

A total of 2124 pregnant women in primary care were included in the study. Data were derived from the Dutch national database, Perined, complemented with data from questionnaires completed by pregnant women. A stepwise-wedge design was employed; multilevel intention-to-treat analyses and propensity score matching were the main analytic approaches. Propensity score matching resulted in sample sizes of 305 nulliparous women in both the individual care (IC) and the matched control group (control-IC) and 267 in the CP and control-CP groups. For multiparous women, 354 matches were found for IC and control-IC groups and 152 for CP and control-CP groups. Main outcome measures were maternal, birth, and neonatal outcomes.

RESULTS

Compared with the control-CP group receiving standard antenatal care, nulliparous women participating in CP had a lower risk of maternal hypertensive disorders (odds ratio [OR], 0.53; 95% CI, 0.30-0.93) and for the composite adverse maternal outcome (OR, 0.52; 95% CI, 0.33-0.82). Breastfeeding initiation rates were higher amongst nulliparous (OR, 2.23; 95% CI, 134-3.69) and multiparous women (OR, 1.62; 95% CI, 1.00-2.62) participating in CP compared with women in the control-CP group.

CONCLUSION

Nulliparous women in CP were at lower risk of developing hypertensive disorders during pregnancy and, consequently, at lower risk of having adverse maternal outcomes. The results confirmed our hypothesis that both nulliparous and multiparous women who participated in CP would have higher breastfeeding rates compared with women receiving standard antenatal care.

Promoting informed decision making about maternal pertussis vaccination: the systematic development of an online tailored decision aid and a centering-based group antenatal care intervention

Introduction

Maintaining and enhancing vaccine confidence continues to be a challenge. Making an informed decision not only helps to avoid potential future regret but also reduces susceptibility to misinformation. There is an urgent need for interventions that facilitate informed decision-making about vaccines. This paper describes the systematic development of two interventions designed to promote informed decision making and indirectly, acceptance of maternal pertussis vaccination (MPV) in the Netherlands.

Materials and methods

The 6-step Intervention Mapping (IM) protocol was used for the development of an online tailored decision aid and Centering Pregnancy-based Group Antenatal Care (CP) intervention. A needs assessment was done using empirical literature and conducting a survey and focus groups (1), intervention objectives were formulated at the behavior and determinants levels (2), theoretical methods of behavior change were selected and translated into practical applications (3), which were further developed into the two interventions using user-centered design (4). Finally, plans were developed for implementation (5), and evaluation (6) of the interventions.

Results

The needs assessment showed that pregnant women often based their decision about MPV on information sourced online and conversations with their partners, obstetric care providers, and peers. Responding to these findings, we systematically developed two interactive, theory-based interventions. We created an online tailored decision aid, subjecting it to four iterations of testing among pregnant women, including those with low literacy levels. Participants evaluated prototypes of the intervention positively on relevance and usability. In addition, a CP intervention was developed with midwives.

Conclusion

Using IM resulted in the creation of an online decision aid and CP intervention to promote informed decision making regarding MPV. This description of the systematic development of the interventions not only serves to illustrate design rationales, it will also aid the interpretation of the evaluation of the interventions, the development of future interventions promoting informed decision and acceptance of vaccines, and comparisons with other interventions.

Maternal satisfaction with group care: a systematic review

OBJECTIVE

This review examined the quantitative relationship between group care and overall maternal satisfaction compared with standard individual care.

DATA SOURCES

We searched CINAHL, Clinical Trials, The Cochrane Library, PubMed, Scopus, and Web of Science databases from the beginning of 2003 through June 2023.

STUDY ELIGIBILITY CRITERIA

We included studies that reported the association between overall maternal satisfaction and centering-based perinatal care where the control group was standard individual care. We included randomized and observational designs.

METHODS

Screening and independent data extraction were carried out by 4 researchers. We extracted data on study characteristics, population, design, intervention characteristics, satisfaction measurement, and outcome. Quality assessment was performed using the Cochrane tools for Clinical Trials (RoB2) and observational studies (ROBINS-I). We summarized the study, intervention, and satisfaction measurement characteristics. We presented the effect estimates of each study descriptively using a forest plot without performing an overall meta-analysis. Meta-analysis could not be performed because of variations in study designs and methods used to measure satisfaction. We presented studies reporting mean values and odds ratios in 2 separate plots. The presentation of studies in forest plots was organized by type of study design.

RESULTS

A total of 7685 women participated in the studies included in the review. We found that most studies (ie, 17/20) report higher satisfaction with group care than standard individual care. Some of the noted results are lower satisfaction with group care in both studies in Sweden and 1 of the 2 studies from Canada. Higher satisfaction was present in 14 of 15 studies reporting CenteringPregnancy, Group Antenatal Care (1 study), and Adapted CenteringPregnancy (1 study). Although indicative of higher maternal satisfaction, the results are often based on statistically insignificant effect estimates with wide confidence intervals derived from small sample sizes.

CONCLUSION

The evidence confirms higher maternal satisfaction with group care than with standard care. This likely reflects group care methodology, which combines clinical assessment, facilitated health promotion discussion, and community-building opportunities. This evidence will be helpful for the implementation of group care globally.

The effect of home nurse visits on infant weight and breastfeeding: Systematic review and meta-analysis

AIMS

The primary aim of this systematic review and meta-analysis is to evaluate the effects of home nurse visiting on infant weight and breastfeeding; the secondary aim is to determine the duration, frequency and content of home visits.

METHODS

A systematic search of the PubMed, CINAHL, Embase (Ovid), Web of Science, Google Scholar and DergiPark databases for publications between September 2000 and January 2019 was conducted using established methods in compliance with the PRISMA-P declaration guideline. Two authors independently evaluated the studies for inclusion and bias, extracted the data and checked their accuracy.

RESULTS

This meta-analysis includes a total of 34 studies, 28 on breastfeeding and nine on infant weight. The average effect size of the 28 studies investigating the effect on breastfeeding was found to be OR: 2.24; 95% CI: 1.73-2.90; p < 0.001. The average effect size of the nine studies investigating the effect on infant weight was found to be ES: 0.197; 95% CI: 0.027-0.368; p < 0.05.

CONCLUSION

There is an association between nurse home visits and breastfeeding and infant weight. Home visits by nurses should continue to remain within the nursing role and be analysed appropriately for mother and baby health.

Promoting informed decision-making about maternal pertussis vaccination in Centering Pregnancy group-antenatal care: A feasibility study

PROBLEM

Effective interventions are needed to promote informed decision making about vaccination.

BACKGROUND

We developed a group-antenatal care (CP; Centering Pregnancy) intervention, i.e., a session about MPV within existing group-care settings, to promote informed decision making about Maternal Pertussis Vaccination in the Netherlands.

AIM

This study aimed to assess (1) to what extent the intervention was implemented as intended, (2) to what extent the intervention met the needs and wishes of pregnant individuals and midwives facilitating CP.

METHODS

We conducted exploratory interviews with 6 CP facilitators and 10 CP participants to assess the implementation of the intervention, and how the intervention and its different components were perceived. Interviews were analysed using thematic analysis. In addition, we conducted a pre- and post-intervention survey amongst 35 participants, measuring knowledge about MPV, and MPV attitude and intention.

RESULTS

The CP intervention was implemented as intended in 6 out of 7 groups. Participants were positive about the interactive CP-methods used to discuss MPV. Participants and facilitators evaluated the intervention as positive and relevant, although the intervention was time-consuming, and some participants had already made the de decision about MPV. Those who had not yet decided indicated that the session was helpful for their decision.

DISCUSSION AND CONCLUSION

Discussing MPV in CP care settings is a feasible strategy to support decision making about MPV during pregnancy. The intervention could be improved by discussing the MPV sooner than 16-18 weeks of pregnancy. A larger-scale study is needed to assess effects on MPV uptake and informed decision making.

Broadening the Environmental Lens to Include Social and Structural Determinants of Women's Health Disparities

BACKGROUND

Due to the physical, metabolic, and hormonal changes before, during, and after pregnancy, women-defined here as people assigned female at birth-are particularly susceptible to environmental insults. Racism, a driving force of social determinants of health, exacerbates this susceptibility by affecting exposure to both chemical and nonchemical stressors to create women's health disparities.

OBJECTIVES

To better understand and address social and structural determinants of women's health disparities, the National Institute of Environmental Health Sciences (NIEHS) hosted a workshop focused on the environmental impacts on women's health disparities and reproductive health in April 2022. This commentary summarizes foundational research and unique insights shared by workshop participants, who emphasized the need to broaden the definition of the environment to include upstream social and structural determinants of health. We also summarize current challenges and recommendations, as discussed by workshop participants, to address women's environmental and reproductive health disparities.

DISCUSSION

The challenges related to women's health equity, as identified by workshop attendees, included developing research approaches to better capture the social and structural environment in both human and animal studies, integrating environmental health principles into clinical care, and implementing more inclusive publishing and funding approaches. Workshop participants discussed recommendations in each of these areas that encourage interdisciplinary collaboration among researchers, clinicians, funders, publishers, and community members. https://doi.org/10.1289/EHP12996.

California's Comprehensive Perinatal Services Program and birth outcomes

Introduction

California's Medicaid (Medi-Cal) sponsors Comprehensive Perinatal Services Program (CPSP), a program with enhanced perinatal care for women (more education, nutritional supplements, and psychosocial counseling/support). Past evaluations of CPSP's effectiveness in birth outcomes were limited to pilot programs and yielded mixed results.

Methods

We used 2012-2016 California's statewide data about singleton live births with any receipt of prenatal care (N = 2,385,811) to examine whether Medi-Cal with CPSP enrollment was associated with lower odds of preterm birth (PTB), spontaneous PTB, and low birthweight (LBW) than non-CPSP births. With three binary variables of PTB, spontaneous PTB, and LBW as the response variables, three multilevel logistic models were used to compare the outcomes of participants enrolled in Medi-Cal with CPSP against those with private insurance, adjusting for maternal factors and county-level covariates.

Results

Logistic models showed that participants enrolled to Medi-Cal with CPSP [n (%) = 89,009 (3.7)] had lower odds of PTB, spontaneous PTB and LBW, respectively, as compared with those with private insurance [n (%) = 1,133,140 (47.2)]. Within the Medi-Cal sub-population, the CPSP enrollment was associated with lower odds of PTB, SPTB and LBW than Medicaid beneficiaries without CPSP [n (%) = 967,094 (40.3)].

Discussion

With statewide data, these findings revealed a robust link between CPSP enrollment and better birth outcomes. Expanding access to comprehensive prenatal services could be an important strategy to improve birth outcomes.

Inflammatory markers in serum and placenta in a randomized controlled trial of group prenatal care

BACKGROUND

Racial and socioeconomic disparities in preterm birth and small for gestational age births are growing in the United States, increasing the burden of morbidity and mortality particularly among Black women and birthing persons and their infants. Group prenatal care is one of the only interventions to show potential to reduce the disparity, but the mechanism is unclear.

OBJECTIVE

The goal of this project was to identify if group prenatal care, when compared with individual prenatal care, was associated with a reduction in systemic inflammation during pregnancy and a lower prevalence of inflammatory lesions in the placenta at delivery.

STUDY DESIGN

The Psychosocial Intervention and Inflammation in Centering Study was a prospective cohort study that exclusively enrolled participants from a large randomized controlled trial of group prenatal care (the Cradle study, R01HD082311, ClinicalTrials.gov: NCT02640638) that was performed at a single site in Greenville, South Carolina, from 2016 to 2020. In the Cradle study, patients were randomized to either group prenatal care or individual prenatal care, and survey data were collected during the second and third trimesters. The Psychosocial Intervention and Inflammation in Centering Study cohort additionally provided serum samples at these 2 survey time points and permitted collection of placental biopsies for inflammatory and histologic analysis, respectively. We examined associations between group prenatal care treatment and a composite of z scored serum inflammatory biomarkers (C-reactive protein, interleukin-6, interleukin-1 receptor antagonist, interleukin-10, and tumor necrosis factor α) in both the second and third trimesters and the association with the prevalence of acute and chronic maternal placental inflammatory lesions. Analyses were conducted using the intent to treat principle, and the results were also examined by attendance of visits in the assigned treatment group (modified intent to treat and median or more number of visits) and were stratified by race and ethnicity.

RESULTS

A total of 1256 of 1375 (92%) Cradle participants who were approached enrolled in the Psychosocial Intervention and Inflammation in Centering Study, which included 54% of all the Cradle participants. The Psychosocial Intervention and Inflammation in Centering Study cohort did not differ from the Cradle cohort by demographic or clinical characteristics. Among the 1256 Psychosocial Intervention and Inflammation in Centering Study participants, 1133 (89.6%) had placental data available for analysis. Among those, 549 were assigned to group prenatal care and 584 of 1133 were assigned to individual prenatal care. In the intent to treat and modified intent to treat cohorts, participation in group prenatal care was associated with a higher serum inflammatory score, but it was not associated with an increased prevalence of placental inflammatory lesions. In the stratified analyses, group prenatal care was associated with a higher second trimester inflammatory biomarker composite (modified intent to treat: B=1.17; P=.02; and median or more visits: B=1.24; P=.05) among Hispanic or Latine participants.

CONCLUSION

Unexpectedly, group prenatal care was associated with higher maternal serum inflammation during pregnancy, especially among Hispanic or Latine participants.

The effects of CenteringPregnancy on maternal and infant health outcomes: a moderation analysis

BACKGROUND

CenteringPregnancy (CP) has been expected to produce beneficial outcomes for women and their infants. However, previous studies paid little attention to testing variations in CP's effects across women from different demographic groups. This study aimed to test how multiple demographic factors (obesity, race, ethnicity, marital status and socioeconomic status) moderate CP's effects on health outcomes.

METHODS

This study employed a quasi-experimental design. De-identified hospital birth data were collected from 216 CP participants and 1159 non-CP participants. We estimated the average treatment effect of CP on outcome variables as a baseline. Then we estimated the average marginal effect of CP by adding each of the moderating variables in regression adjustment models.

RESULTS

CP produced salutary effects among those who were obese or overweight and unmarried as well as women with lower socioeconomic status. These salutary effects were also strengthened as maternal age increased. However, CP was ineffective for Hispanic/Latinx women.

CONCLUSIONS

CP produced more beneficial health outcomes for high-risk women such as obese, unmarried women and those with lower socioeconomic status. These are meaningful findings from a public health perspective.

National assessment of obstetrics and gynecology and family medicine residents' experiences with CenteringPregnancy group prenatal care

OBJECTIVE

To examine family medicine (FM) and obstetrician-gynecologist (OB/GYN) residents' experiences with CenteringPregnancy (CP) group prenatal care (GPNC) as a correlate to perceived likelihood of implementing CP in future practice, as well as knowledge, level of support, and perceived barriers to implementation.

METHODS

We conducted a repeated cross-sectional study annually from 2017 to 2019 with FM and OB/GYN residents from residency programs in the United States licensed to operate CP. We applied adjusted logistic regression models to identify predictors of intentions to engage with CP in future practice.

RESULTS

Of 212 FM and 176 OB/GYN residents included in analysis, 67.01% of respondents intended to participate as a facilitator in CP in future practice and 51.80% of respondents were willing to talk to decision makers about establishing CP. Both FM and OB/GYN residents who spent more than 15 h engaged with CP and who expressed support towards CP were more likely to participate as a facilitator. FM residents who received residency-based training on CP and who were more familiar with CP reported higher intention to participate as a facilitator, while OB/GYN residents who had higher levels of engagement with CP were more likely to report an intention to participate as a facilitator.

CONCLUSION

Engagement with and support towards CP during residency are key factors in residents' intention to practice CP in the future. To encourage future adoption of CP among residents, consider maximizing resident engagement with the model in hours of exposure and level of engagement, including hosting residency-based trainings on CP for FM residents.

Long-term cost savings with Centering-based group antenatal care

INTRODUCTION

Group antenatal care (gANC) is a group-based care-model combining routine antenatal care, with health assessment, education, and community building. GANC has shown positive results on perinatal outcomes. However, midwives in Dutch primary care have reported higher costs when providing gANC. The purpose of this study was to assess the effect of replacing individual prenatal care (IC) by gANC on (expected future) health care costs and health outcomes.

METHODS

We performed an exploratory cost-benefit analysis comparing costs and consequences of gANC with those of IC, using a hypothetical cohort of 12,894 women in gANC. Primary input data were derived from a stepped wedge cluster randomized controlled trial carried out in the Netherlands, assessing both health and psychosocial effects of gANC comparing them with IC. Other data was retrieved from available literature and an online questionnaire among midwifery practices. The main outcome measure was differential cost of gANC and lifetime direct healthcare costs related to the effects of gANC compared to IC (price level 2019).

RESULTS

Results showed that gANC comes at a differential cost of €45 extra per person when compared to IC. However, projected healthcare cost-savings related to increased breastfeeding rates, reduced prevalence of pregnancy induced hypertension and less postpartum smoking, lead to an average net cost-savings of €67 per gANC participant.

DISCUSSION

Although gANC shows better health- and psychosocial outcomes when compared to IC, it is more costly to provide. However, findings indicate that the differential costs of gANC are off-set by long-term healthcare cost-savings.

Randomized Controlled Trial on the Effect of Group Versus Individual Prenatal Care on Psychosocial Outcomes

OBJECTIVE

To assess the effect of group prenatal care (GPNC) compared with individual prenatal care (IPNC) on psychosocial outcomes in late pregnancy, including potential differences in outcomes by subgroups.

DESIGN

Randomized controlled trial.

SETTING

An academic medical center in the southeastern United States.

PARTICIPANTS

A total of 2,348 women with low-risk pregnancies who entered prenatal care before 20 6/7 weeks gestation were randomized to GPNC (n = 1,175) or IPNC (n = 1,173) and stratified by self-reported race and ethnicity.

METHODS

We surveyed participants during enrollment (M = 12.21 weeks gestation) and in late pregnancy (M = 32.51 weeks gestation). We used standard measures related to stress, anxiety, coping strategies, empowerment, depression symptoms, and stress management practices in an intent-to-treat regression analysis. To account for nonadherence to GPNC treatment, we used an instrumental variable approach.

RESULTS

The response rates were high, with 78.69% of participants in the GPNC group and 83.89% of participants in the IPNC group completing the surveys. We found similar patterns for both groups, including decrease in distress and increase in anxiety between surveys and comparable levels of pregnancy empowerment and stress management at the second survey. We identified greater use of coping strategies for participants in the GPNC group, particularly those who identified as Black or had low levels of partner support.

CONCLUSION

Group prenatal care did not affect stress and anxiety in late pregnancy; however, the increased use of coping strategies may suggest a benefit of GPNC for some participants.

Contributions of CenteringPregnancy to women's health behaviours, health literacy, and health care use in the Netherlands

The objective of this study was to assess the effects of CenteringPregnancy (CP) in the Netherlands on different health outcomes. A stepped wedged cluster randomized trial was used, including 2132 women of approximately 12 weeks of gestation, from thirteen primary care midwifery centres in and around Leiden, Netherlands. Data collection was done through self-administered questionnaires. Multilevel intention-to-treat analysis and propensity score matching for the entire group and separately for nulliparous- and multiparous women were employed. The main outcomes were: health behaviour, health literacy, psychological outcomes, health care use, and satisfaction with care. Women's participation in CP is associated with lower alcohol consumption after birth (OR = 0.59, 95 %CI 0.42-0.84), greater consistency with norms for healthy eating and physical activity (β = 0.19, 95 %CI 0.02-0.37), and higher knowledge about pregnancy (β = 0.05, 95 %CI 0.01-0.08). Compared to the control group, nulliparous women who participating in CP reported better compliance to the norm for healthy eating and physical activity (β = 0.28, 95 %CI0.06-0.51)) and multiparous CP participants consumed less alcohol after giving birth (OR = 0.42, 95 %CI 0.23-0.78). Health care use and satisfaction rates were significantly higher among CP participants. A non-significant trend toward lower smoking rates was documented among CP participants. Overall, the results of this study reveal a positive (postpartum) impact on fostering healthy behaviours among participants.

Deep representation learning identifies associations between physical activity and sleep patterns during pregnancy and prematurity

Preterm birth (PTB) is the leading cause of infant mortality globally. Research has focused on developing predictive models for PTB without prioritizing cost-effective interventions. Physical activity and sleep present unique opportunities for interventions in low- and middle-income populations (LMICs). However, objective measurement of physical activity and sleep remains challenging and self-reported metrics suffer from low-resolution and accuracy. In this study, we use physical activity data collected using a wearable device comprising over 181,944 h of data across N = 1083 patients. Using a new state-of-the art deep learning time-series classification architecture, we develop a 'clock' of healthy dynamics during pregnancy by using gestational age (GA) as a surrogate for progression of pregnancy. We also develop novel interpretability algorithms that integrate unsupervised clustering, model error analysis, feature attribution, and automated actigraphy analysis, allowing for model interpretation with respect to sleep, activity, and clinical variables. Our model performs significantly better than 7 other machine learning and AI methods for modeling the progression of pregnancy. We found that deviations from a normal 'clock' of physical activity and sleep changes during pregnancy are strongly associated with pregnancy outcomes. When our model underestimates GA, there are 0.52 fewer preterm births than expected (P = 1.01e - 67, permutation test) and when our model overestimates GA, there are 1.44 times (P = 2.82e - 39, permutation test) more preterm births than expected. Model error is negatively correlated with interdaily stability (P = 0.043, Spearman's), indicating that our model assigns a more advanced GA when an individual's daily rhythms are less precise. Supporting this, our model attributes higher importance to sleep periods in predicting higher-than-actual GA, relative to lower-than-actual GA (P = 1.01e - 21, Mann-Whitney U). Combining prediction and interpretability allows us to signal when activity behaviors alter the likelihood of preterm birth and advocates for the development of clinical decision support through passive monitoring and exercise habit and sleep recommendations, which can be easily implemented in LMICs.

Participation in the CenteringPregnancy Program and Pregnancy-Induced Hypertension

INTRODUCTION

CenteringPregnancy emphasizes nutrition, learning, and peer support through a group meeting format in contrast to the standard of prenatal care that maximizes a pregnant patient's time with their provider. It was hypothesized that the program may yield a reduced risk of pregnancy-induced hypertension. In this observational study, authors examined the impacts of the CenteringPregnancy program versus those of standard of prenatal care on pregnancy-induced hypertension.

METHODS

In 2021, birth certificate data were linked to hospital discharge records of women who delivered in obstetric clinics in the Midlands of South Carolina between 2015 and 2019. Logistic regression models were used to estimate the association between CenteringPregnancy participation (n=547) and any pregnancy-induced hypertension and specific pregnancy-induced hypertension diagnoses (gestational hypertension/unspecified hypertension, mild pre-eclampsia, and severe pre-eclampsia/eclampsia). Propensity score techniques (e.g., inverse probability of treatment weighting) were used to adjust for self-selection into the program versus into standard of prenatal care.

RESULTS

CenteringPregnancy participants had higher odds of developing any pregnancy-induced hypertension under all specifications (OR=1.48, 95% CI=1.15, 1.92) and specifically gestational hypertension/unspecified hypertension (OR=1.76, 95% CI=1.28, 2.42) than those in standard of prenatal care. However, CenteringPregnancy participants did not experience significantly higher odds of mild pre-eclampsia (OR=1.06, 95% CI=0.65, 1.78) and severe pre-eclampsia/eclampsia (OR=1.21, 95% CI=0.78, 1.89) compared with standard of prenatal care participants.

CONCLUSIONS

Participation in CenteringPregnancy was associated with higher odds of pregnancy-induced hypertension, particularly gestational hypertension, than participation in standard of prenatal care. Additional research is warranted to definitely rule out selection bias and identify contributing factor(s) that increased pregnancy-induced hypertension despite efforts to improve pregnancy-related health outcomes among CenteringPregnancy participants.

Group Prenatal Care

Group prenatal care (GPC) is a novel model of health care delivery for pregnant patients. In GPC, a small group of patients of similar gestational age meet at scheduled intervals for both medical care and facilitated educational discussions. This care model encourages better communication and engages patients and providers in a supportive community. There is evidence that GPC leads to improved patient and provider satisfaction, health equity, and maternal and neonatal outcomes. Delivery of prenatal care in a group setting is a significant change from the traditional model and takes willingness, planning, and commitment for implementation and continued success.

Anticipated benefits and challenges of implementing group care in Suriname's maternity and child care sector: a contextual analysis

BACKGROUND

Suriname is a uppermiddle-income country with a relatively high prevalence of preventable pregnancy complications. Access to and usage of high-quality maternity care services are lacking. The implementation of group care (GC) may yield maternal and child health improvements. However, before introducing a complex intervention it is pivotal to develop an understanding of the local context to inform the implementation process.

METHODS

A context analysis was conducted to identify local needs toward maternity and postnatal care services, and to assess contextual factor relevant to implementability of GC. During a Rapid Qualitative Inquiry, 63 online and face-to-face semi-structured interviews were held with parents, community members, on-and off-site healthcare professionals, policy makers, and one focus group with parents was conducted. Audio recordings were transcribed in verbatim and analysed using thematic analysis and Framework Method. The Consolidated Framework for Implementation Research served as a base for the coding tree, which was complemented with inductively derived codes.

RESULTS

Ten themes related to implementability, one theme related to sustainability, and seven themes related to reaching and participation of the target population in GC were identified. Factors related to health care professionals (e.g., workload, compatibility, ownership, role clarity), to GC, to recipients and to planning impact the implementability of GC, while sustainability is in particular hampered by sparse financial and human resources. Reach affects both implementability and sustainability. Yet, outer setting and attitudinal barriers of health professionals will likely affect reach.

CONCLUSIONS

Multi-layered contextual factors impact not only implementability and sustainability of GC, but also reach of parents. We advise future researchers and implementors of GC to investigate not only determinants for implementability and sustainability, but also those factors that may hamper, or facilitate up-take. Practical, attitudinal and cultural barriers to GC participation need to be examined. Themes identified in this study will inspire the development of adaptations and implementation strategies at a later stage.

Group vs Individual Prenatal Care and Gestational Diabetes Outcomes: A Secondary Analysis of a Randomized Clinical Trial

Importance

The impact of group-based prenatal care (GPNC) model in the US on the risk of gestational diabetes (GD) and related adverse obstetric outcomes is unknown.

Objective

To determine the effects of the GPNC model on risk of GD, its progression, and related adverse obstetric outcomes.

Design, Setting, and Participants

This is a single-site, parallel-group, randomized clinical trial conducted between February 2016 and March 2020 at a large health care system in Greenville, South Carolina. Participants were individuals aged 14 to 45 years with pregnancies earlier than 21 weeks' gestational age; follow-up continued to 8 weeks post partum. This study used an intention-to-treat analysis, and data were analyzed from March 2021 to July 2022.

Interventions

Eligible participants were randomized to receive either CenteringPregnancy, a widely used GPNC model, with 10 group-based sessions or traditional individual prenatal care (IPNC).

Main Outcomes and Measures

The primary outcome was the incidence of GD diagnosed between 24 and 30 weeks of gestation. The secondary outcomes included progression to A2 GD (ie, GD treated with medications) and GD-related adverse obstetric outcomes (ie, preeclampsia, cesarean delivery, and large for gestational age). Log binomial models were performed to estimate risk differences (RDs), 95% CIs, and P values between GPNC and IPNC groups, adjusting for all baseline covariates.

Results

Of all 2348 participants (mean [SD] age, 25.1 [5.4] years; 952 Black participants [40.5%]; 502 Hispanic participants [21.4%]; 863 White participants [36.8%]), 1176 participants were randomized to the GPNC group and 1174 were randomized to the IPNC group. Among all participants, 2144 (91.3%) completed a GD screening (1072 participants [91.3%] in GPNC vs 1071 [91.2%] in IPNC). Overall, 157 participants (6.7%) developed GD, and there was no difference in GD incidence between the GPNC (83 participants [7.1%]) and IPNC (74 participants [6.3%]) groups, with an adjusted RD of 0.7% (95% CI, -1.2% to 2.7%). Among participants with GD, GPNC did not reduce the risk of progression to A2 GD (adjusted RD, -6.1%; 95% CI, -21.3% to 9.1%), preeclampsia (adjusted RD, -7.9%; 95% CI, -17.8% to 1.9%), cesarean delivery (adjusted RD, -8.2%; 95% CI, -12.2% to 13.9%), and large for gestational age (adjusted RD, -1.2%; 95% CI, -6.1% to 3.8%) compared with IPNC.

Conclusions and Relevance

In this secondary analysis of a randomized clinical trial among medically low-risk pregnant individuals, the risk of GD was similar between participants who received GPNC intervention and traditional IPNC, indicating that GPNC may be a feasible treatment option for some patients.

A scoping review of interventions seeking to improve aspects of patient-provider relationships involving Black pregnant and post-partum people

AIMS

To provide a map of the evidence related to interventions targeting patient-provider relationships among Black perinatal people.

DESIGN

A scoping review of the literature was conducted.

DATA SOURCES

The database search included English language articles within three databases: PubMed, the Cumulative Index for Nursing and Allied Health Literature, and Medline without date restriction on June 15 and16 2022.

REVIEW METHODS

This scoping review used the six-stage process first described by Arksey and O'Malley and recommended by the Joanna Briggs Institute: (1) specify the research question, (2) identify relevant literature, (3) select studies, (4) map out the data, (5) synthesize, and report the results and (6) consult experts. Studies were included if they (1) reported results of intervention studies related to patient-provider interaction, (2) were written in English and (3) were original research. The articles were reviewed with content analysis methodology to categorize and interpret the findings.

RESULTS

Studies included randomized controlled trials (n = 5) and qualitative studies (n = 3) published between 2001 and 2018. Black pregnant people made up more than half of the participants in five of the eight studies (63%). Interventions were divided into three categories: delivery models (n = 4), mHealth risk assessment tools (n = 2) and patient-provider communication tools (n = 2).

CONCLUSION

This study addressed the unknown role of patient-provider relationship interventions in improving the quality of care received by Black perinatal people. Findings suggest that structural and interpersonal components may have the potential to improve outcomes for Black pregnant people but could be further improved if culturally tailored. Further research is urgently needed to address discrimination and stigma in patient-provider relationships. The findings of this study could inform novel intervention development and should drive research.

IMPACT

A scoping review determined that there are no interventions with Black pregnant people which targeted discrimination and bias in patient-provider relationships.

NO PATIENT OR PUBLIC CONTRIBUTION

The authors did not include stakeholders such as patients, service users, caregivers or members of the public in the development of this scoping review, as it is a work that serves to set the stage for further community-based work. The results will however be communicated to community members at a planned advisory board in the future.

Group Prenatal Care vs. Traditional Prenatal Care: A Parity-Matched Comparison of Perinatal Outcomes in a Rural Community

PURPOSE

Prenatal care is important for positive outcomes for both mother and infant. The traditional one-on-one method remains the most common. This study aimed to compare perinatal outcomes of patients attending group prenatal care with traditional prenatal care. Most previously published comparisons did not match for parity, a key predictor of perinatal outcome.

DESCRIPTION

We collected perinatal outcome data for 137 group prenatal care patients and 137 traditional prenatal care patients, matched for contemporaneous delivery and parity, who delivered at our small rural hospital during 2015-2016. We included key public health variables, including the initiation of breastfeeding, and smoking at the time of delivery.

ASSESSMENT

There was no difference between the two groups for maternal age or infant ethnicity, induced or augmented labor, preterm deliveries, APGAR scores less than 7, low birth weight, NICU admissions, or cesarean deliveries. Group care patients had more prenatal visits and were more likely to initiate breastfeeding and were less likely to report smoking at the time of delivery.

CONCLUSION

In our rural population matched for contemporaneous delivery and parity, we found no difference in traditional perinatal outcome measures and that group care was positively associated with the key public health variables of not smoking and initiating breastfeeding. If future studies in other populations have similar findings, it may be wise to provide group care more widely to rural populations.

Group antenatal care: findings from a pilot randomised controlled trial of REACH Pregnancy Circles

BACKGROUND

Antenatal care has the potential to impact positively on maternal and child outcomes, but traditional models of care in the UK have been shown to have limitations and particularly for those from deprived populations. Group antenatal care is an alternative model to traditional individual care. It combines conventional aspects of antenatal assessment with group discussion and support. Delivery of group antenatal care has been shown to be successful in various countries; there is now a need for a formal trial in the UK.

METHOD

An individual randomised controlled trial (RCT) of a model of group care (Pregnancy Circles) delivered in NHS settings serving populations with high levels of deprivation and diversity was conducted in an inner London NHS trust. This was an external pilot study for a potential fully powered RCT with integral economic evaluation. The pilot aimed to explore the feasibility of methods for the full trial. Inclusion criteria included pregnant with a due date in a certain range, 16 + years and living within specified geographic areas. Data were analysed for completeness and usability in a full trial; no hypothesis testing for between-group differences in outcome measures was undertaken. Pre-specified progression criteria corresponding to five feasibility measures were set. Additional aims were to assess the utility of our proposed outcome measures and different data collection routes. A process evaluation utilising interviews and observations was conducted.

RESULTS

Seventy-four participants were randomised, two more than the a priori target. Three Pregnancy Circles of eight sessions each were run. Interviews were undertaken with ten pregnant participants, seven midwives and four other stakeholders; two observations of intervention sessions were conducted. Progression criteria were met at sufficient levels for all five measures: available recruitment numbers, recruitment rate, intervention uptake and retention and questionnaire completion rates. Outcome measure assessments showed feasibility and sufficient completion rates; the development of an economic evaluation composite measure of a 'positive healthy birth' was initiated.

CONCLUSION

Our pilot findings indicate that a full RCT would be feasible to conduct with a few adjustments related to recruitment processes, language support, accessibility of intervention premises and outcome assessment.
