Rural-Urban Disparities in Adverse Maternal Outcomes in the United States, 2016-2019

Cardio-obstetrics de novo: a state-level, evidence-based approach for addressing maternal mortality and severe maternal morbidity in Georgia

Georgia has a higher rate of severe maternal morbidity and mortality when compared with the rest of the United States. Evidence gained from the Georgia Maternal Mortality Review Committee identified areas of focus for high-yield clinical initiatives for improvement in maternal health outcomes. Cardiovascular disease, including cardiomyopathy, coronary conditions, and preeclampsia with or without eclampsia, is the most common cause of pregnancy-related death in non-Hispanic Black women in Georgia. The development of a cardio-obstetrics program is an initiative to advance health equity by decreasing cardiovascular morbidity and mortality. This report describes the following: (1) state-level advocacy for improving maternal health outcomes with funding gained through the legislative process and partnership with a governmental agency; (2) cardio-obstetrics program development based on evidence gained from the maternal mortality review process; and (3) implementation of a cardio-obstetrics service, beginning with a focused approach for capacity building and understanding barriers to care.

A Qualitative Study of Systems-Level Factors That Affect Rural Obstetric Nurses' Work During Clinical Emergencies

BACKGROUND

Maternal morbidity and mortality is rising in the United States. Previous studies focus on patient attributes, and most of the national data are based on research performed at urban tertiary care centers. Although it is well understood that nurses affect patient outcomes, there is scant evidence to understand the nurse work system, and no studies have specifically studied rural nurses. The authors sought to understand the systems-level factors affecting rural obstetric nurses when their patients experience clinical deterioration.

METHODS

The research team used a qualitative descriptive approach, including a modified critical incident technique, in interviews with bedside nurses (n = 7) and physicians (n = 4) to understand what happens when patients experience clinical deterioration. Physicians were included to better understand the systems in which nurses work. Clinicians were interviewed at three rural hospitals in New England, with a mean births per year of 190.

FINDINGS

Six systems-level factors/themes were identified: (1) shortages of resources; (2) need for teamwork; (3) physicians' multiple conflicting and simultaneous responsibilities, such as seeing patients in the office while women labor on the hospital floor; (4) need for all team members to be at the top of their game; (5) process issues during high-acuity patient transfer, including difficulty finding available beds at tertiary care centers; and (6) insufficient policies that take low-resource contexts into account, such as requiring two registered nurses to remove emergency medications from the medication cabinet.

CONCLUSION

Rural nurses need policies and protocols that are written with their hospital context in mind. Hospitals may need outside support for content expertise, but policies should be co-created with clinicians with rural practice experience.

Global maternal mortality projections by urban/rural location and education level: a simulation-based analysis

Background

Maternal mortality remains a challenge in global health, with well-known disparities across countries. However, less is known about disparities in maternal health by subgroups within countries. The aim of this study is to estimate maternal health indicators for subgroups of women within each country.

Methods

In this simulation-based analysis, we used the empirically calibrated Global Maternal Health (GMatH) microsimulation model to estimate a range of maternal health indicators by subgroup (urban/rural location and level of education) for 200 countries/territories from 1990 to 2050. Education levels were defined as low (less than primary), middle (less than secondary), and high (completed secondary or higher). The model simulates the reproductive lifecycle of each woman, accounting for individual-level factors such as family planning preferences, biological factors (e.g., anemia), and history of maternal complications, and how these factors vary by subgroup. We also estimated the impact of scaling up women's education on projected maternal health outcomes compared to clinical and health system-focused interventions.

Findings

We find large subgroup differences in maternal health outcomes, with an estimated global maternal mortality ratio (MMR) in 2022 of 292 (95% UI 250-341) for rural women and 100 (95% UI 84-116) for urban women, and 536 (95% UI 450-594), 143 (95% UI 117-174), and 85 (95% UI 67-108) for low, middle, and high education levels, respectively. Ensuring all women complete secondary school is associated with a large impact on the projected global MMR in 2030 (97 [95% UI 76-120]) compared to current trends (167 [95% UI 142-188]), with especially large improvements in countries such as Afghanistan, Chad, Madagascar, Niger, and Yemen.

Interpretation

Substantial subgroup disparities present a challenge for global maternal health and health equity. Outcomes are especially poor for rural women with low education, highlighting the need to ensure that policy interventions adequately address barriers to care in rural areas, and the importance of investing in social determinants of health, such as women's education, in addition to health system interventions to improve maternal health for all women.

Virtual Obstetric Hospitalist Support for Obstetric Emergencies and Deliveries: The Mayo Clinic Experience

Objective: To implement use of obstetric (OB) hospitalist telemedicine services (TeleOB) to support clinicians facing OB emergencies in low-resource hospital settings. Methods: TeleOB was staffed by OB hospitalists working at a tertiary maternity center. The service was available via real-time high-definition audio/video technology for providers at 17 outlying hospitals across a health system spanning two states. The initial 25 service activations are described. Results: TeleOB supported 17 deliveries, two postpartum emergency department (ED) consultations, and four antenatal ED consultations. In 10 of 17 (59%) deliveries, teleneonatology was jointly activated to support neonatal resuscitation. Sixteen (94%) deliveries occurred in multiparas, and five (29%) resulted from spontaneous preterm labor. Eighty percent (20/25) of activations occurred in facilities without maternity services. Conclusions: A TeleOB service staffed by OB hospitalists successfully supports hospitals in an integrated health care system. TeleOB is feasible for support of hospitals with no delivery facilities or with limited maternity care resources.

Rural/urban disparities in the trends and outcomes of peripartum cardiomyopathy in delivery hospitalizations

BACKGROUND

Rural-urban disparities in peripartum cardiomyopathy (PPCM) are not well known. We examined rural-urban differences in maternal, fetal, and cardiovascular outcomes in PPCM during delivery hospitalizations.

METHODS

We used 2003-2020 data from the National Inpatient Sample for delivery hospitalizations in individuals with PPCM. The 9th and 10th editions of the International Classification of Diseases were used to identify PPCM and cardiovascular, maternal, and fetal outcomes. Rural and urban hospitalizations for PPCM were 1:1 propensity score-matched using relevant clinical and sociodemographic variables. Odds of in-hospital mortality were assessed using logistic regression.

RESULTS

Among 72,880 delivery hospitalizations with PPCM, 4,571 occurred in rural locations, while 68,309 occurred in urban locations. After propensity matching, there were a total of 4,571 rural-urban pairs. There was significantly higher in-hospital mortality in urban compared to rural hospitalizations (adjusted OR 1.54, 95% CI 1.10-1.89). Urban PPCM hospitalizations had significantly higher cardiogenic shock (2.9% vs. 1.3%), mechanical circulatory support (1.0% vs. 0.6%), cardiac arrest (2.3% vs. 0.9%), and VT/VF (4.5% vs. 2.1%, all p <.05). Additionally, urban PPCM hospitalizations had worse maternal and fetal outcomes as compared to rural hospitalizations, including higher preterm delivery, gestational diabetes, and fetal death (all p<.05). Notably, significantly more rural individuals were transferred to a short-term hospital (including tertiary care centers) compared to urban individuals (13.5% vs. 3.2%, p<.0001).

CONCLUSIONS

There are significant rural-urban disparities in delivery hospitalizations with PPCM. Worse outcomes were associated with urban hospitalizations, while rural PPCM hospitalizations were associated with increased transfers, suggesting inadequate resources and advanced sickness.

2024 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Nationwide study of in-hospital maternal mortality in Ecuador, 2015-2022

Objective

This study aimed to analyze estimates of in-hospital delivery-related maternal mortality and sociodemographic factors influencing this mortality in Ecuador during 2015 to 2022.

Methods

Data from publicly accessible registries from the Ecuadorian National Institute of Statistics and Censuses were analyzed. Maternal mortality ratios (MMRs) were calculated, and bivariate and multivariate logistic regression models were used to obtain unadjusted and adjusted odds ratios.

Results

There was an increase in in-hospital delivery-related maternal deaths in Ecuador from 2015 to 2022: MMRs increased from 3.70 maternal deaths/100 000 live births in 2015 to 32.22 in 2020 and 18.94 in 2022. Manabí province had the highest rate, at 84.85 maternal deaths/100 000 live births between 2015 and 2022. Women from ethnic minorities had a higher probability of in-hospital delivery-related mortality, with an adjusted odds ratio (AOR) of 9.59 (95% confidence interval [95% CI]: 6.98 to 13.18). More maternal deaths were also observed in private health care facilities (AOR: 1.99, 95% CI: 1.4 to 2.84).

Conclusions

Efforts to reduce maternal mortality have stagnated in recent years. During the COVID-19 pandemic in 2020, an increase in maternal deaths in hospital settings was observed in Ecuador. Although the pandemic might have contributed to the stagnation of maternal mortality estimates, socioeconomic, demographic and clinical factors play key roles in the complexity of trends in maternal mortality. The results from this study emphasize the importance of addressing not only the medical aspects of care but also the social determinants of health and disparities in the health care system.

The evolution of health system planning and implementation of maternal telehealth services during the COVID-19 Pandemic

Background

Differential access to healthcare is associated with disparities in maternal outcomes. Telehealth is one approach for improving access to maternal services. However, little is known regarding how health systems leverage telehealth to close the access gap.

Objective

This study examines how health systems have approached decisions about using telehealth for maternal services before and during the COVID-19 public health emergency and what factors were considered.

Methods

We conducted semi-structured interviews with 15 health system leaders between July and October 2021 and June and August 2022. We used a rapid analysis followed by a content analysis approach.

Results

Five health systems did not provide maternal telehealth services before the PHE due to a lack of reimbursement. Two health systems provided limited services as research endeavors, and one had integrated telehealth into routine maternity care. During the PHE, all transitioned to telehealth, with the primary consideration being patient and staff safety. At the time of the interview, key considerations shifted to patient access, patient preferences, patient complexity, return on investment, and staff burnout. However, several barriers impacted telehealth use, including coverage of portable devices and connectivity. These issues were reported to be common among underinsured, low-income, and rural patients. Health systems with particularly advanced capabilities worked on approaches to fill access gaps for these patients.

Conclusion

Some health systems prioritized telehealth to improve access to high-quality maternal services for patients at the highest risk of adverse outcomes. However, policy and patient-level barriers to equitable implementation of these services persist.
