Race, ethnicity, and indications for primary cesarean birth: Associations within a national birth center registry

BACKGROUND

Racial and ethnic disparities in cesarean rates in the United States are well documented. This study investigated whether cesarean inequities persist in midwife-led birth center care, including for individuals with the lowest medical risk.

METHODS

National registry records of 174,230 childbearing people enrolled in care in 115 midwifery-led birth center practices between 2007 and 2022 were analyzed for primary cesarean rates and indications by race and ethnicity. The lowest medical risk subsample (n = 70,521) was analyzed for independent drivers of cesarean birth.

RESULTS

Primary cesarean rates among nulliparas (15.5%) and multiparas (5.7%) were low for all enrollees. Among nulliparas in the lowest-risk subsample, non-Latinx Black (aOR = 1.37; 95% CI, 1.15-1.63), Latinx (aOR = 1.51; 95% CI, 1.32-1.73), and Asian participants (aOR = 1.48; 95% CI, 1.19-1.85) remained at higher risk for primary cesarean than White participants. Among multiparas, only Black participants experienced a higher primary cesarean risk (aOR = 1.49; 95% CI, 1.02-2.18). Intrapartum transfers from birth centers were equivalent or lower for Black (14.0%, p = 0.345) and Latinx (12.7%, p < 0.001) enrollees. Black participants experienced a higher proportion of primary cesareans attributed to non-reassuring fetal status, regardless of risk factors. Place of admission was a stronger predictor of primary cesarean than race or ethnicity.

CONCLUSIONS

Place of first admission in labor was the strongest predictor of cesarean. Racism as a chronic stressor and a determinant of clinical decision-making reduces choice in birth settings and may increase cesarean rates. Research on components of birth settings that drive inequitable outcomes is warranted.

Neonatal morbidity and mortality in birth centers in the United States 2018-2021: An observational study of low-risk birthing individuals

BACKGROUND

Many studies reporting neonatal outcomes in birth centers include births with risk factors not acceptable for birth center care using the evidence-based CABC criteria. Accurate comparisons of outcomes by birth setting for low-risk patients are needed.

METHODS

Data from the public Natality Detailed File from 2018 to 2021 were used. Logistic regression, including adjusted and unadjusted odds ratios, compared neonatal outcomes (chorioamnionitis, Apgar scores, resuscitation, intensive care, seizures, and death) between centers and hospitals. Covariates included maternal diabetes, body mass index, age, parity, and demographic characteristics.

RESULTS

The sample included 8,738,711 births (8,698,432 (99.53%) in hospitals and 40,279 (0.46%) in birth centers). There were no significant differences in neonatal deaths (aOR 1.037; 95% CI [0.515, 2.088]; p-value 0.918) or seizures (aOR 0.666; 95% CI [0.315, 1.411]; p-value 0.289). Measures of morbidity either not significantly different or less likely to occur in birth centers compared to hospitals included chorioamnionitis (aOR 0.032; 95% CI [0.020, 0.052]; p-value < 0.001), Apgar score < 4 (aOR 0.814, 95% CI [0.638, 1.039], p-value 0.099), Apgar score < 7 (aOR 1.075, 95% CI [0.979, 1.180], p-value 0.130), ventilation >6 h (aOR 0.349; [0.281,0.433], p-value < 0.001), and intensive care admission (aOR 0.356; 95% CI [0.328, 0.386], p-value < 0.001). Birth centers had higher odds of assisted neonatal ventilation for <6 h as compared to hospitals (aOR 1.373; 95% CI [1.293, 1.457], p-value < 0.001).

CONCLUSION

Neonatal deaths and seizures were not significantly different between freestanding birth centers and hospitals. Chorioamnionitis, Apgar scores < 4, and intensive care admission were less likely to occur in birth centers.

The evolution of Ericaceae flowers and their pollination syndromes at a global scale

PREMISE

Floral evolution in large clades is difficult to study not only because of the number of species involved, but also because they often are geographically widespread and include a diversity of outcrossing pollination systems. The cosmopolitan blueberry family (Ericaceae) is one such example, most notably pollinated by bees and multiple clades of nectarivorous birds.

METHODS

We combined data on floral traits, pollination ecology, and geography with a comprehensive phylogeny to examine the structuring of floral diversity across pollination systems and continents. We focused on ornithophilous systems to test the hypothesis that some Old World Ericaceae were pollinated by now-extinct hummingbirds.

RESULTS

Despite some support for floral differentiation at a continental scale, we found a large amount of variability within and among landmasses, due to both phylogenetic conservatism and parallel evolution. We found support for floral differentiation in anther and corolla traits across pollination systems, including among different ornithophilous systems. Corolla traits show inconclusive evidence that some Old World Ericaceae were pollinated by hummingbirds, while anther traits show stronger evidence. Some major shifts in floral traits are associated with changes in pollination system, but shifts within bee systems are likely also important.

CONCLUSIONS

Studying the floral evolution of large, morphologically diverse, and widespread clades is feasible. We demonstrate that continent-specific radiations have led to widespread parallel evolution of floral morphology. We show that traits outside of the perianth may hold important clues to the ecological history of lineages.

Safe prevention of Clostridium difficile using infectious disease guidelines at an urban hospital in North Carolina

Clostridium difficile causes nearly 500 000 annual infections in the USA. A total of 15 000-30 000 US deaths annually and greater than US$4.8 billion dollars are related to Clostridium difficile infection (CDI). Length of hospital stay is 2.8 -5.5 additional days and inpatient costs are estimated at US$3000-US$15 400 per episode. One major cause of CDI is misuse and overuse of antibiotics. The Centers for Disease Control and Prevention reports that 30%-50% of antibiotics prescribed in hospitals are unnecessary or inappropriate. Patients with unexplained or three or greater unformed stools in 24 hours are candidates for testing of CDI.Prior to implementation, an analysis at the local level was conducted to determine possible causes of CDI influence. Chart auditing at this urban hospital revealed that 1 out of 23 (4%) providers were treating UTIs according to hospital protocol (A. Richmond, personal communication, 6 March 2018). The standardized infection ratio in 2017, which compares the predicted to the actual infection rate, at this hospital was 1.266 for CDI. Having a solid antibiotic stewardship in place is imperative to limit antibiotic related and resistant infections. During an observational study, only one out of nine (11%) staff followed contact precaution policies at this hospital.

Strong Start Innovation: Equitable Outcomes Across Public and Privately Insured Clients Receiving Birth Center Care

INTRODUCTION

The Birth Center model of care is a health care delivery innovation in its fourth decade of demonstration across the United States. The purpose of this research was to evaluate the model's potential for decreasing poverty-related health disparities among childbearing families.

METHODS

Between 2013 and 2017, 26,259 childbearing people received care within the 45 Center for Medicare and Medicaid Innovation Strong Start birth center sites. Secondary analysis of the prospective American Association of Birth Centers Perinatal Data Registry was conducted. Descriptive statistics described sociobehavioral, medical risk factors, and core clinical outcomes to inform the logistic regression model. Privately insured consumers were independently compared with 2 subgroups of Medicaid beneficiaries: Strong Start enrollees (midwifery-led care with peer counselors) and non-Strong Start Medicaid beneficiaries (midwifery-led care without peer counselors).

RESULTS

After controlling for medical risk factors, Strong Start Medicaid beneficiaries achieved similar outcomes to privately insured consumers with no significant differences in maternal or newborn outcomes between groups. Perinatal outcomes included induction of labor (adjusted odds ratio [aOR], 0.86; 95% CI 0.61-1.13), epidural analgesia use (aOR, 1.00; 95% CI, 0.68-1.48), cesarean birth (aOR, 1.16; 95% CI, 0.87-1.53), exclusive breastfeeding on discharge (aOR, 1.11; 95% CI, 0.48-2.56), low Apgar score at 5 minutes (aOR, 1.23; 95% CI, 0.86-1.83), low birth weight (aOR, 1.12; 95% CI, 0.77-1.64), and antepartum transfer of care after the first prenatal appointment (aOR, 1.53; 95% CI, 0.97-2.40). Medicaid beneficiaries who were not enrolled in the Strong Start midwifery-led, peer counselor program demonstrated similar results except for having higher epidural analgesia use (aOR, 1.30; 95% CI, 1.10-1.53) and significantly lower exclusive breastfeeding on discharge (aOR, 0.57; 95% CI, 0.40-0.81) than their privately insured counterparts.

DISCUSSION

The midwifery-led birth center model of care complemented by peer counselors demonstrated a pathway to achieve health equity.

Increasing effective postpartum care in an obstetric clinic using ACOG's postpartum toolkit

BACKGROUND

Approximately 69% of maternal mortality occurs in the postpartum period. Contributing factors include the absence of preparation of pregnant women for the postpartum period during the antenatal period, postpartum follow-up care not being scheduled until 6 weeks after childbirth, and the lack of further care coordination.

AIM

The aim of this project was to increase the frequency of effective postpartum care visits to 80% in 8 weeks at an urban obstetric clinic.

METHODS

A quality improvement project was conducted through four Plan-Do-Study-Act cycles over 8 weeks.

INTERVENTIONS

Postpartum Readiness & Awareness Tools (PRATs) were reviewed with patients during their late third trimester, to review postpartum warning signs that warrant further evaluation. A population health registry was created to manage early follow-up for newly postpartum patients, to ensure their recovery was progressing normally. A note template was created and implemented to guide the completion of comprehensive postpartum visits.

RESULTS

Over 8 weeks, 188 patients received 1 of the 3 standardized interventions. Effective postpartum visits increased to 88%. The PRATs increased patient postpartum warning sign knowledge, with a project mean risk factor knowledge score of 6 (Goal = 5). The population health registry drove right care by ensuring early postpartum patients were recovering as expected, as seen by a project mean right-care score of 16 (Goal = 12). The note template increased the effectiveness of postpartum visits, with a mean effective postpartum care score of 10 (Goal = 10).

CONCLUSIONS

The PRATs, population health registry, and note template collectively increased the quality and effectiveness of postpartum care.

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.

Implementing an Evidence-Based Bundle to Reduce Early Labor Admissions and Increase Adherence to Labor Arrest Guidelines: A Quality Improvement Initiative

BACKGROUND

At many hospitals, the cesarean birth rate among nulliparous term singleton vertex (NTSV) pregnancies is higher than World Health Organization benchmarks. Reducing NTSV cesarean birth is a national quality imperative. The aim of this initiative was to implement an evidence-based bundle at an urban community teaching hospital in at least 50% of labors in 60 days in order to reduce early labor admissions and increase adherence to evidence-based labor management guidelines shown to decrease cesarean birth.

METHODS

Chart audits, root-cause analysis, and staff engagement informed bundle development. An early labor triage guide, labor walking path, partograph, and pre-cesarean checklist were implemented to drive change. Four Rapid Cycle Plan Do Study Act cycles were conducted over 8 weeks.

RESULTS

The bundle was implemented in 58% of births. The bundle reduced early labor admissions labor from 41% to 25%. Team knowledge reflecting current guidelines in labor management increased 35% and 100% of cesareans for labor arrest met criteria. Patient satisfaction scores exceeded 98%.

CONCLUSIONS

Implementing an evidenced-based bundle was effective in reducing early labor admissions and increasing utilization of and adherence to labor management guidelines.

IMPLICATIONS FOR NURSING

Implementation of evidence-based bundles has the potential to achieve meaningful quality improvements in maternity care.

Rural resilience: The role of birth centers in the United States

PURPOSE

To explore the role of the birth center model of care in rural health and maternity care delivery in the United States.

METHODS

All childbearing families enrolled in care at an American Association of Birth Centers Perinatal Data Registry^TM user sites between 2012 and 2020 are included in this descriptive analysis.

FINDINGS

Between 2012 and 2020, 88 574 childbearing families enrolled in care with 82 American Association of Birth Centers Perinatal Data Registry^TM user sites. Quality outcomes exceeded national benchmarks across all geographic regions in both rural and urban settings. A stable and predictable rate of transfer to a higher level of care was demonstrated across geographic regions, with over half of the population remaining appropriate for birth center level of care throughout the perinatal episode of care. Controlling for socio demographic and medical risk factors, outcomes were as favorable for clients in rural areas compared with urban and suburban communities.

CONCLUSIONS

Rural populations cared for within the birth center model of care experienced high-quality outcomes.

HEALTH POLICY IMPLICATIONS

A major focus of the United States maternity care reform should be the expansion of access to birth center models of care, especially in underserved areas such as rural communities.

Right care: Improving timeliness and promoting preventive health in a lower socioeconomic reproductive health clinic

BACKGROUND

Missed prevention opportunities are a financial burden to the US health care system and result in excess consumption of resources, reduced quality of life, increased morbidity, and premature death.

LOCAL PROBLEM

High staff turnover and inefficient practices at a local health department caused long patient wait times and missed opportunities for preventive health care. The project aim was to improve timeliness through Right Care in a lower socioeconomic reproductive health clinic while decreasing patient cycle time by 10% in 90 days.

METHODS

We used four plan-do-study-act cycles incorporating tests of change that focused on team and patient engagement and two process changes. The interventions included a care coordination huddle, an infant feeding decision aid to better understand patient values, a sexual health screening tool to identify prevention opportunities, and a redesigned patient-centered discharge process to improve efficiency.

RESULTS

Over 90 days, the receipt of Right Care increased while patient cycle time decreased by 2.6%. The team improved function with a mean huddle effectiveness score increase from 2 to 4.4 (1-5 Likert scale). Intent to breastfeed increased by 49% (35%-52%), and identification of preventive care needs increased by 320% (15%-63%). Preventive care follow-up remained unchanged at 26% with the new discharge process, identifying weaknesses in the health department referral systems.

CONCLUSIONS

Standardized tools and processes improved primary prevention opportunities at a local health department while reducing patient cycle time. The tools improved documentation of intent to exclusively breastfeed, increased preventive care identification, and streamlined the discharge process; while demonstrating a systems-level gap for long-term follow-up.

Promoting effective care: Reducing primary cesarean births through team engagement and standardization of care at a community hospital

BACKGROUND

The overuse of cesarean births (CBs) in the United States has led to increased rates of maternal and infant morbidity and mortality.

LOCAL PROBLEM

The nulliparous, term, singleton, vertex (NTSV) CB rate at this community hospital was 32.3% in 2017, well above the Healthy People 2020 target of 23.9%. The aim of this project was to decrease the NTSV CB rate by five percentage points in a 7-week period.

METHODS

Four plan-do-study-act cycles focused on team engagement and process changes. Team huddles utilizing the best practices checklist to standardize care for labor dystocia and abnormal fetal tracings, as well as audits of unplanned CB, were implemented. SQUIRE guidelines were used in the preparation of this manuscript.

RESULTS

Over 7 weeks, 13 of 55 NTSV patients gave birth by cesarean, resulting in an NTSV CB rate of 23.6%. Fifty-three huddles were held by 218 staff members for 28 patients. Team engagement scores improved from 85% to 98%. Although the effective care CB scores trended upward, the overall mean was 51%.

CONCLUSIONS

Interdisciplinary team huddles, coupled with the use of a best practices checklist and feedback from audits, achieved a more effective use of CB in the NTSV patient population.

Strong Start in birth centers: Socio-demographic characteristics, care processes, and outcomes for mothers and newborns

BACKGROUND

A recent Center for Medicare and Medicaid Innovation report evaluated the four-year Strong Start for Mothers and Newborns Initiative, which sought to improve maternal and newborn outcomes through exploration of three enhanced, evidence-based care models. This paper reports the socio-demographic characteristics, care processes, and outcomes for mothers and newborns engaged in care with American Association of Birth Centers (AABC) sites.

METHODS

The authors examined data for 6424 Medicaid or Children's Health Insurance Program (CHIP) beneficiaries in birth center care who gave birth between 2013 and 2017. Using data from the AABC Perinatal Data Registry™, descriptive statistics were used to evaluate socio-behavioral and medical risks, and core perinatal quality outcomes. Comparisons are made between outcomes in the AABC sample and national data during the study period.

RESULTS

Childbearing mothers enrolled at AABC sites had diverse socio-behavioral risk factors similar to the national profile. The AABC sites exceeded national quality benchmarks for low birthweight (3.28%), preterm birth (4.42%), and primary cesarean birth (8.56%). Racial disparities in perinatal indicators were present within the Strong Start sample; however, they were at narrower margins than in national data. The enhanced model of care was notable for use of midwifery-led prenatal, labor, and birth care and decreased hospital admission.

CONCLUSIONS

Birth center care improves population health, patient experience, and value. The model demonstrates the potential to decrease racial disparity and improve population health. Reduction of regulatory barriers and implementation of sustainable reimbursement are warranted to move the model to scale for Medicaid beneficiaries nationwide.

Not Missing the Opportunity: Improving Depression Screening and Follow-Up in a Multicultural Community

BACKGROUND

Screening for depression and documenting follow-up is a National Quality Forum-endorsed measure. Yet only seven states report depression screening and follow-up, making it the fourth-least-reported measure on the Medicaid Adult Core Set. In 2016 a multicultural health center found that only 9.1% of clients were screened and followed up for depression. This quality improvement project was conducted to increase the efficacy of Screening, Brief Intervention, and Referral to Treatment (SBIRT) for depression to 75% for screen-positive clients.

METHODS

Four Plan-Do-Study-Act (PDSA) cycles in a 90-day period focused on depression screening, patient engagement, population health management, and team building were used. The package of interventions-use of written standardized Patient Health Questionnaire (PHQ) screening tools in six languages, the Option Grid™ for clients with positive PHQ screens, a "right care" tracking log for those clients, and team meetings and in-services to support capacity building-were operationalized using a point-of-care notebook that created a physical reminder and trigger for the use of the intervention tools. Surveys, charts, and registry data were analyzed to evaluate the population health impact of the interventions.

RESULTS

Provision of evidence-based care increased to 71.4%, and adherence to follow-up increased from 33.3% to 60.0%. Screening in the client's preferred language increased the rate to 85.2%, identifying a positive PHQ incidence of 45.5%.

CONCLUSION

Rapid-cycle improvement with a population health focus demonstrated improved depression screening and follow-up within a multicultural community health center. Outcomes were attributed to team engagement and the use of standardized tools. These processes can be applied to other primary care settings.
