Midwifery and Birth Centers Under State Medicaid Programs: Current Limits to Beneficiary Access to a High-Value Model of Care

"It's my Home away from Home:" A hermeneutic phenomenological study exploring decision-making experiences of choosing a freestanding birth centre for perinatal care

PROBLEM

The high-value, midwifery-led birth centre (BC) model of care is underutilized in the United States, a country with high rates of obstetric intervention and maternal morbidity and mortality.

BACKGROUND

Birth setting decision-making is a complex, preference-sensitive, and resource-dependent process. Understanding how people choose BCs for care may help increase the utilization of BCs and generate positive perinatal outcomes.

AIM

This study explores the decision-making experiences of people with Medicaid insurance who chose to give birth in a BC in Massachusetts by gathering interview data to interpret and provide meaning about their selection of birth setting.

METHODS

We employed a hermeneutic phenomenology study to interview people about their decision to give birth in a BC. Interview data were coded using a hybrid deductive-inductive approach and analyzed using reflexive thematic analysis to interpret and provide meaning.

FINDINGS

Twelve women participated in the study. Five themes emerged that described participants' decision-making processes: 1) Stepping Away from "the System," 2) Decision-Making with External Influences, 3) Accessing BC Care, 4) Finding a Home at the BC, and 5) Decision-Making as a Temporal Process.

DISCUSSION

The decision to choose a BC was a dynamic process that occurred over time and was influenced by factors such as the quality of care, accessibility, external influences, and the physical environment.

CONCLUSION

Prioritizing an individual's capacity to choose their birth setting and fostering awareness about options in the context of informed decision-making are pivotal steps toward attaining equity in perinatal health. Securing public insurance coverage and equitable reimbursement for BCs represent essential policies aimed at facilitating universal access to the BC model for all people.

Low birthweight rate differences associated with distinct perinatal staffing mixes at federally funded health centers

Health centers (sometimes referred to as "federally qualified health centers") can play an important role in addressing perinatal inequities. However, there is limited information on how different staffing models in health centers contribute to perinatal outcomes, including the availability of certified nurse midwives (CNMs). Using 2011-2021 Uniform Data System files, we examined 4 staffing models in 1385 health centers: those with no CNMs or obstetricians-gynecologists (OBs) ("non-CNM/OB"), CNM-only, OB-only, and both CNMs and OBs ("CNM/OB"). We predicted adjusted low birthweight (LBW) rates across these staffing types using a generalized linear model approach, adjusting for both time and center fixed effects as well as relevant patient, staffing, organizational, and community characteristics. We found that CNM-only health centers had the lowest LBW rates across all staffing models (7.6%) and non-CNM/OB centers had the highest (10.1%). Among Black births, LBW rates ranged from 10.1% (CNM-only) to 13.5% (non-CNM/OB). Findings indicate the importance of building and supporting the CNM workforce and ensuring adequate staffing at health centers, particularly as part of a comprehensive approach to addressing inequities in perinatal outcomes including addressing the scope of practice of CNMs, as more CNM-staff health centers were in areas with independent scope of practice.

Parity Moderates the Socioeconomic Predictors of Birth Setting Choice

BACKGROUND

The increase in the number of people choosing community birth has raised interest in understanding the factors that influence birth setting choices. This study investigates how parity influences the association between maternal socioeconomic factors and choice of community versus hospital birth.

METHODS

We used 2009-2021 US birth certificate data to identify community births (planned home or birth center births), parity, and maternal characteristics, including Women, Infants, and Children (WIC) program participation, race, ethnicity, educational attainment, marital status, body mass index (BMI), and age. Parity was interacted with each covariate in a multivariable logistic regression model of birth setting.

RESULTS

Among 26,526,010 eligible births, 58% were to multiparous mothers, with 1.9% occurring in a birth center or at home. For most maternal characteristics, associations with community birth were stronger in the multiparous group compared to the nulliparous group. For example, being married was associated with greater odds of community birth in both groups, but the strength of this association was greater within the multiparous group (odds ratio 4.00 vs. 1.94, interaction p < 0.001). The same pattern (stronger association with community birth in the multiparous group than in the primiparous group) was observed for race/ethnicity, educational attainment, and WIC participation, all of which were associated with lower odds of community birth.

CONCLUSION

This study shows that parity significantly moderates associations between maternal socioeconomic characteristics and birth setting, implying studies of decision-making in this context should purposively stratify samples and analyses by parity.

The birth center model of care: Staffing, business characteristics, and core clinical outcomes

OBJECTIVES

Interest in expanding access to the birth center model is growing. The purpose of this research is to describe birth center staffing models and business characteristics and explore relationships to perinatal outcomes.

METHODS

This descriptive analysis includes a convenience sample of all 84 birth center sites that participated in the AABC Site Survey and AABC Perinatal Data Registry between 2012 and 2020. Selected independent variables include staffing model (CNM/CM or CPM/LM), legal entity status, birth volume/year, and hours of midwifery call/week. Perinatal outcomes include rates of induction of labor, cesarean birth, exclusive breastfeeding, birthweight in pounds, low APGAR scores, and neonatal intensive care admission.

RESULTS

The birth center model of care is demonstrated to be safe and effective, across a variety of staffing and business models. Outcomes for both CNM/CM and CPM/LM models of care exceed national benchmarks for perinatal quality with low induction, cesarean, NICU admission, and high rates of breastfeeding. Within the sample of medically low-risk multiparas, variations in clinical outcomes were correlated with business characteristics of the birth center, specifically annual birth volume. Increased induction of labor and cesarean birth, with decreased success breastfeeding, were present within practices characterized as high volume (>200 births/year). The research demonstrates decreased access to the birth center model of care for Black and Hispanic populations.

CONCLUSIONS FOR PRACTICE

Between 2012 and 2020, 84 birth centers across the United States engaged in 90,580 episodes of perinatal care. Continued policy development is necessary to provide risk-appropriate care for populations of healthy, medically low-risk consumers.

Association of prenatal stress with distance to delivery for pregnant women in Western North Carolina

PURPOSE

Rural areas throughout the US continue to see closures of maternity wards and decreasing access to prenatal and intrapartum care. Studies examining closure's impacts have demonstrated both positive and negative effects on maternal and neonatal outcomes of mortality and morbidity. Our study aims to build on growing evidence from Canada and Scandinavia that suggests increased travel time to give birth is associated with increased emotional and financial stress for rural pregnant women.

METHODS

Pregnant patients at 7 clinic sites in western North Carolina were invited to complete the Rural Pregnancy Experience Scale (RPES) while waiting for their prenatal appointments. Results were analyzed using adjusted linear regressions to examine the correlation between RPES scores and self-reported distance to anticipated birth location as well as RPES scores with recent local labor and delivery closure.

FINDINGS

A total of 174 participants completed the survey and met inclusion criteria. For every 10 min increase in travel distance to the patient's anticipated place of delivery, RPES scores increased by an average of 0.72 points. Participants who reported a recent labor and delivery unit closure near them saw average increases of 2.52 on the RPES.

CONCLUSIONS

Our findings are consistent with the growing body of literature internationally that demonstrates the distance required to travel to delivery location is associated with increased stress among rural pregnant women.

Midwifery in the Time of COVID-19: An Exploratory Study from the Perspectives of Community Midwives

INTRODUCTION

An increasing number of people in the United States are choosing to give birth in a community setting. There is anecdotal evidence that interest in community birth further increased during the COVID-19 pandemic. The purpose of this study was to explore the needs, barriers, and successes of community midwifery during COVID-19 and how these experiences can inform future efforts to support and sustain community-based midwifery.

METHODS

This qualitative study used semi-structured interviews conducted online with 11 community midwives from the greater Seattle area who were practicing during the COVID-19 pandemic. Interviews were transcribed verbatim from audio recordings. Transcripts were analyzed using deductive and inductive coding.

RESULTS

Participants all reported challenges navigating COVID-19-related changes, such as implementing personal protective equipment, using telehealth, and limiting support people at births. Although participants saw an increased interest in their services, the increase in uncompensated labor contributed to burnout. Many participants described regularly encountering stigma and misperceptions about community midwifery when their patients transferred to hospitals, which occurred more often among clients who chose midwifery primarily because of COVID-19 concerns. Community midwives expressed a desire to increase interprofessional collaboration with hospitals to sustain the future of community midwifery.

CONCLUSIONS

The experiences of community midwives practicing during the COVID-19 pandemic indicate strategies to reduce burnout and support community midwifery during the pandemic, natural disasters, and beyond. These strategies include improved interprofessional collaboration and higher reimbursement rates.

Midwifery Autonomy and Employment Changes During the Early COVID-19 Pandemic

INTRODUCTION

The COVID-19 pandemic presented the midwifery workforce with challenges for maintaining access to high-quality care and safety for patients and perinatal care providers. This study analyzed associations between different types of professional autonomy and changes in midwives' employment and compensation during the early months of the pandemic.

METHODS

An online survey distributed to midwifery practices in fall 2020 compared midwives' employment and compensation in February 2020 and September 2020. Chi-square analysis determined associations between those data and measures of midwives' autonomy: state practice environment, midwifery practice ownership, intrapartum practice setting, and midwifery participation in practice decision-making.

RESULTS

Participants included lead midwives from 727 practices, representing 50 states and the District of Columbia. Full-time equivalent (FTE) positions and number of full-time midwives were stable for 77% of practices, part-time employment for 83%, and salaries for 72%. Of the remaining practices, more practices lost FTE positions, full-time positions, part-time positions, and salary (18%, 15%, 9%, and 18%, respectively) than gained (11%, 8%, 8%, and 9%, respectively). Early retirements and furloughs were experienced by 9% of practices, and 18% lost benefits. However, midwifery practice ownership was significantly associated with increased salaries (20.3% vs 7.1%; P < .001) and decreased loss of benefits (7.8% vs 19.9%; P = .002) and furloughs (3.8 vs 10.1%; P = .04). Community-based practice was significantly associated with increased FTE positions (19.0% vs 8.8%; P = .005), part-time positions (17.4% vs 5.1%; P < .001), and salary (19.7% vs 7.0%; P < .001), as well as decreased loss of benefits (11.5% vs 21.1%; P = .02) and early retirement (1.4% vs 6.6%; P = .03). State practice environment and participation in practice decision-making were not directly associated with employment and compensation changes.

DISCUSSION

Policies should facilitate midwifery practice ownership and the expansion and integration of community birth settings for greater perinatal care workforce stability, greater flexibility to respond to disasters, and improved patient access to care and health outcomes.

Choosing a Birth Setting: A Shared Decision-Making Approach

Perinatal outcomes vary widely depending on individual birth settings (birth center, home, and hospital). The purpose of this case study is to explore a patient-centered, shared decision-making approach to achieve an informed, values-based choice about birth settings. Engaging in a shared decision-making approach regarding birth setting options would support people to have the information and ability to judge for themselves how benefits and risks across birth center, home, and hospital settings would best fit with their values and personal health. A patient decision aid about birth setting options could facilitate increased equity regarding access to birth settings that offer improved perinatal health outcomes, helping to reduce perinatal health disparities in the United States.

Place of Birth Preferences and Relationship to Maternal and Newborn Outcomes Within the American Association of Birth Centers Perinatal Data Registry, 2007-2020

PURPOSE

The purpose of this study was to describe sociodemographic variations in client preference for birthplace and relationships to perinatal health outcomes.

METHODS

Descriptive data analysis (raw number, percentages, and means) showed that preference for birthplace varied across racial and ethnic categories as well as sociodemographic categories including educational status, body mass index, payer status, marital status, and gravidity. A subsample of medically low-risk childbearing people, qualified for birth center admission in labor, was analyzed to assess variations in maternal and newborn outcomes by site of first admission in labor.

RESULTS

While overall clinical outcomes exceeded national benchmarks across all places of admission in the sample, disparities were noted including higher cesarean birth rates among Black and Hispanic people. This variation was larger within the population of people who preferred to be admitted to the hospital in labor in the absence of medical indication.

CONCLUSION

This study supports that the birth center model provides safe delivery care across the intersections of US sociodemographics. Findings from this study highlight the importance of increased access and choice in place of birth for improving health equity, including decreasing cesarean birth and increasing breastfeeding initiation.

Salary and Workload of Midwives Across Birth Center Practice Types and State Regulatory Structures

INTRODUCTION

Expansion of the midwifery-led birth center model of care is one pathway to improving maternal and newborn health. There are a variety of practice types among birth centers and a range of state regulatory structures of midwifery practice across the United States. This study investigated how those variations relate to pay and workload for midwives at birth centers.

METHODS

Data from the American Association of Birth Centers Practice Survey and the Bureau of Labor Statistics' report on occupational employment and wage statistics were analyzed to explore how midwife salaries and workload at birth centers compare within and beyond the birth center model.

RESULTS

Survey results from 161 birth centers across the United States demonstrate wide variation in nurse-midwife salaries and are inconsistent with nurse-midwife salaries across all settings as reported by the Bureau of Labor Statistics. The reported number of hours worked by midwives within the birth center model is high. Salaries of midwives who work in birth center-only practices were consistently lower than salaries of midwives who worked in blended birth center and hospital practices, independent of the midwife's level of experience, geographic region of the country, and state regulatory structure.

DISCUSSION

Further research is needed to understand how to bring salaries and workload for midwives at birth centers into alignment with national averages.

Early Perinatal Workforce Adaptations to the COVID-19 Pandemic

The objective of this study was to describe the system's initial pandemic response from the perspectives of perinatal health workers and to identify opportunities for improved future preparedness. An exploratory survey was designed to identify perinatal practice changes and workforce challenges during the initial weeks of the COVID-19 pandemic. The survey included baseline data collection and weekly surveys. A total of 181 nurses, midwives, and physicians completed the baseline survey; 84% completed at least 1 weekly survey. Multiple practice changes were reported. About half of respondents (50.8%) felt the changes protected patients, but fewer (33.7%) felt the changes protected themselves. Most respondents providing out-of-hospital birth services (91.4%) reported increased requests for transfer to out-of-hospital birth. Reports of shortages of personnel and supplies occurred as early as the week ending March 23 and were reported by at least 10% of respondents through April 27. Shortages were reported by as many as 38.7% (personal protective equipment), 36.8% (supplies), and 18.5% (personnel) of respondents. This study identified several opportunities to improve the pandemic response. Evaluation of practice changes and timing of supply shortages reported during this emergency can be used to prepare evidence-based recommendations for the next pandemic.
