Social determinants of health in pulmonary embolism management and outcome in hospitals: Insights from the United States nationwide inpatient sample

International Clinical Practice Guideline Recommendations for Acute Pulmonary Embolism: Harmony, Dissonance, and Silence

Despite abundant clinical innovation and burgeoning scientific investigation, pulmonary embolism (PE) has continued to pose a diagnostic and management challenge worldwide. Aging populations, patients living with a mounting number of chronic medical conditions, particularly cancer, and increasingly prevalent health care disparities herald a growing burden of PE. In the meantime, navigating expanding strategies for immediate and long-term anticoagulation, as well as advanced therapies, including catheter-based interventions for patients with more severe PE, has become progressively daunting. Accordingly, clinicians frequently turn to evidence-based clinical practice guidelines for diagnostic and management recommendations. However, numerous international guidelines, heterogeneity in recommendations, as well as areas of uncertainty or omission may leave the readers and clinicians without a clear management pathway. In this review of international PE guidelines, we highlight key areas of consistency, difference, and lack of recommendations (silence) with an emphasis on critical clinical and research needs.

Pulmonary hypertension-related deaths in patients with acute pulmonary embolism in the United States, 2003 to 2020

BACKGROUND

Data regarding the mortality trends in pulmonary embolism (PE)-related mortality in patients with concomitant pulmonary hypertension (PH) are lacking. We assessed the trends in PE-related mortality in patients with concomitant PH in the United States (US) over the past 2 decades and during the first year of the COVID-19 pandemic using data from the Centers for Disease Control and Prevention's (CDC) Wide-ranging ONline Data for Epidemiologic Research (WONDER) dataset.

METHODS

Mortality data were retrieved from the publicly available CDC WONDER mortality dataset from 2003 to 2020. Age-adjusted mortality rates (AAMRs), per 100,000 population, were assessed using Joinpoint regression modelling and expressed as estimated average annual percentage change (AAPC) with relative 95% CIs and stratified by urbanicity, sex, age, and race/ethnicity.

RESULTS

Over the study period, the AAMR for PE/PH-related mortality linearly increased (AAPC: +4.3% [95% CI: 3.7 to 4.9], p < 0.001) without sex differences. The AAMR increase was more pronounced in White individuals (AAPC: +4.8% [95% CI: 4.1 to 5.5], p < 0.001) and in subjects living in rural areas (AAPC: +5.1% [95% CI: 3.8 to 6.4], p < 0.001) compared to those living in urban areas. During the first year of the COVID-19 pandemic there was a significant excess in PE/PH-related mortality among women, older than 65 years and living in rural areas.

CONCLUSIONS

The rate of PE/PH-related mortality in the US is increasing. Although the early diagnosis of PH in patients with acute PE has become easier with improved diagnostic modalities, the mortality rate of these patients remains high.

Racial differences in adoption and outcomes of transcarotid artery revascularization among high-risk adults with carotid artery stenosis

INTRODUCTION

Differential access to new technologies may contribute to racial disparities in surgical outcomes but has not been well-studied in the treatment of carotid artery stenosis. We examined race-based differences in adoption and outcomes of transcarotid artery revascularization (TCAR) among high-risk non-Hispanic (NH) NH Black and NH white adults undergoing carotid revascularization.

METHODS

We conducted a retrospective analysis of TCAR, transfemoral carotid artery stenting (TF-CAS), and carotid endarterectomy (CEA) procedures performed for carotid artery stenosis from 1/2015 to 7/2023 in the Vascular Quality Initiative. NH Black and NH white adults were included if they met Centers for Medicare & Medicaid Services high-risk criteria. Hospitals and physicians were categorized as TCAR-capable if they had previously performed at least one TCAR prior to the time of a given procedure. We fit logistic and linear regressions, adjusted a priori for common demographic, clinical, and disease characteristics, to estimate associations of race with receipt of TCAR (versus CEA or TF-CAS), and to explore associations between race, hospital and physician characteristics, and perioperative composite stroke/death/myocardial infarction.

RESULTS

Of 159,471 high-risk patients undergoing revascularization for carotid artery stenosis (mean age 72 years, 38.5% female, 5.3% NH Black), 28,722 (18.0%) received TCAR, including 16.9% of NH Black adults and 18.1% of NH white adults (P<0.001). After controlling for patient and disease characteristics, NH Black patients were less likely than NH white patients to receive TCAR (aOR 0.92, 95% CI 0.87 to 0.99). The use of TCAR did not vary by race among patients treated at TCAR-capable hospitals (aOR 0.98, 95% CI 0.91 to 1.05) or by TCAR-capable physicians (aOR 1.01, 95% CI 0.93 to 1.10); however, NH Black race was associated with lower odds of receiving treatment in these settings (TCAR-capable hospital: aOR 0.93 [0.88 to 0.98]; TCAR-capable physician: aOR 0.92 [0.87 to 0.98]). NH Black race was associated with higher odds of stroke/death/MI in the full cohort (aOR 1.18, 95% CI 1.03 to 1.36), but not in the subgroup of patients who received TCAR (aOR 0.87, 95% CI 0.56 to 1.34).

CONCLUSIONS

TCAR attenuated racial disparities in perioperative morbidity and mortality associated with carotid revascularization, but NH Black adults were less likely than NH white adults to receive TCAR. Relatively worse access for NH Black adults to technologically-advanced treatment settings may partially explain the broader persistence of race-based differences in carotid revascularization treatment patterns and outcomes.

Mitigating health disparities by improving access to catheter-based therapies for vulnerable patients with acute pulmonary embolism

INTRODUCTION

This study explores the implementation and outcomes of catheter-based thrombectomy (CBT) for acute pulmonary embolism (PE) within a safety-net hospital (SNH), addressing a critical gap in the literature concerning CBT in underserved and vulnerable populations.

METHODS

This is a retrospective study of patients undergoing CBT between October 2020 and January 2024 at a SNH. The primary outcome was 30-day all-cause mortality.

RESULTS

A total of 107 patients (47.6 % female, mean age 58.4 years) underwent CBT for acute PE, with 23 (21.5 %) high-risk and 84 (78.5 %) intermediate-risk PE. Demographically, 64 % identified as Black, 10 % White, 19 % Hispanic or Latino, and 5 % Asian. In terms of insurance coverage, 50 % had private insurance or Medicare, 36 % had Medicaid, and 14 % were uninsured. Notably, 67 % of the patients resided in high poverty rate zip codes and 11 % were non-citizen non-residents. Over a median follow up period of 30 days, 6 (5.6 %) patients expired (all high-risk PE), 3 of whom presented with cardiac arrest. No patients who presented with intermediate-risk PE died at 30 days. There was no difference in 30-day mortality based on race, insurance type, poverty level or citizenship status.

CONCLUSION

Our study findings reveal no disparities in access or outcomes to CBT at our SNH, emphasizing the feasibility and success of implementing PERT and CBT at a SNH, offering a potential model to address healthcare disparities in acute PE on a broader scale.

Racial Disparities and Other Socioeconomic Predictors of Mortality in Acute Pulmonary Embolism Treatment from the National Inpatient Sample

PURPOSE

To explore the significance of socioeconomic factors such as race and ethnicity as predictors of mortality in submassive and massive acute pulmonary embolism (PE).

MATERIALS AND METHODS

Hospitalizations of patients aged >18 years with acute, nonseptic PE from 2016 to 2019 were identified from the National Inpatient Sample and divided into interventional radiology (IR) (catheter-directed thrombolysis and thrombectomy) and non-IR (tissue plasminogen activator) treatments. Statistical analyses calculated significant odds ratios (ORs) via 95% confidence intervals (CIs). The primary outcome of interest was mortality rate. Comorbidities affecting mortality were examined secondarily.

RESULTS

Non-Hispanic (NH) Black, Hispanic, and Asian/Pacific Islander patients were significantly less likely to undergo an IR procedure for acute, nonseptic PE compared with White patients (NH Black, OR, 0.83 [95% CI, 0.76-0.90], P < .05; Hispanic, 0.78 [0.68-0.89], P = .06; Asian/Pacific Islander, 0.71 [0.51-0.98], P = .72); however, these differences were eliminated when propensity score matching was performed for age, biological sex, and primary insurance type or for primary insurance type alone. NH Black patients were significantly more likely to die than White patients, regardless of undergoing non-IR or IR treatment. Overall risk of death was 41% higher for NH Black patients than for White patients (relative risk, 1.41 [95% CI, 1.24-1.60]; P < .001).

CONCLUSIONS

NH Black patients have a higher risk of mortality from acute, nonseptic PE than White patients. Independent of race, undergoing IR management for acute, nonseptic PEs was associated with a lower mortality rate. Matching for primary insurance type eliminates differences in mortality between races, suggesting that socioeconomic status may determine outcomes in acute PE.

Acute Pulmonary Embolism: Evidence, Innovation, and Horizons

PURPOSE OF REVIEW

Pulmonary embolism (PE) is the third most common cause of cardiovascular morbidity and mortality. The goal of this review is to discuss the most up-to-date literature on epidemiology, diagnosis, risk stratification, and management of acute PE.

RECENT FINDINGS

Despite an increase in annual incidence rate of PE in the United States and development of multiple advanced therapies for treatment of acute PE, PE-related mortality is not consistently decreasing across populations. Although multiple risk stratification schemes have been developed, it is still unclear which advanced therapy should be used for the individual patient and optimal timing. Fortunately, multiple randomized clinical trials are underway to answer these questions. Nevertheless, up to 50% of patients have persistent reduced quality of life 6 months after acute PE, termed post-PE syndrome. Despite advances in therapeutic options for management of acute PE, many questions remain unanswered, including optimal risk stratification and management of acute PE.

Social disparities in pulmonary embolism and deep vein thrombosis during the coronavirus disease 2019 pandemic from the Nationwide inpatient Sample

OBJECTIVES

Studies have shown that coronavirus disease 2019 (COVID-19) is associated with a hypercoagulable state. Studies have yet to examine the interconnectedness between COVID-19, hypercoagulability, and socioeconomics. The aim of this work was to investigate socioeconomic factors that may be associated with pulmonary embolism (PE), deep vein thrombosis (DVT), and COVID-19 in the United States.

METHODS

We performed a 1-year (2020) analysis of the National Inpatient Sample database. We identified all adult patients diagnosed with COVID-19, acute PE, or acute DVT using unweighted samples. We calculated the correlation and odds ratio (OR) between COVID-19 and (1) PE and (2) DVT. We executed a univariate analysis followed by a multivariate analysis to examine the effect of different factors on PE and DVT during the COVID-19 pandemic.

RESULTS

We identified 322,319 patients with COVID-19; 78,101 and 67,826 patients were identified with PE and DVT, respectively. PE and DVT, as well as inpatient mortality associated with both conditions, are significantly correlated with COVID-19. The OR between COVID-19 and PE was 2.04, while the OR between COVID-19 and DVT was 1.44. Using multivariate analysis, COVID-19 was associated with a higher incidence of PE (coefficient, 2.05) and DVT (coefficient, 1.42). Other factors that were significantly associated (P < .001) with increased incidence of PE and DVT along with their coefficients, respectively, include Black race (95% confidence interval [CI], 1.23-1.14), top quartile income (95% CI, 1.08-1.16), west region (95% CI, 1.10-1.04), urban teaching facilities (95% CI, 1.09-1.63), large bed size hospitals (95% CI, 1.08-1.29), insufficient insurance (95% CI, 1.88-2.19), hypertension (95% CI, 1.24-1.32), and obesity (95% CI, 1.41-1.25). Factors that were significantly associated (P < .001) with decreased incidence of PE and DVT along with their coefficients, respectively, include Asians/Pacific Islanders (95% CI, 0.52-0.53), female sex (95% CI, 0.79-0.74), homelessness (95% CI, 0.62-0.61), and diabetes mellitus (0.77-0.90).

CONCLUSIONS

In the Nationwide Inpatient Sample, COVID-19 is correlated positively with venous thromboembolism, including its subtypes, PE and DVT. Using a multivariate analysis, Black race, male sex, top quartile income, west region, urban teaching facilities, large bed size hospitals, and insufficient social insurance were associated significantly with an increased incidence of PE and DVT. Asians/Pacific Islanders, female sex, homelessness, and diabetes mellitus were significantly associated decreased incidence of PE and DVT.

Disparities in access to and timing of interventional therapies for pulmonary embolism across the United States

BACKGROUND

Interventional therapies (ITs) are an emerging treatment modality for pulmonary embolism (PE); however, the degree of racial, sex-based, and sociodemographic disparities in access and timing is unknown.

OBJECTIVES

To investigate barriers to access and timing of ITs for PE across the United States.

METHODS

A retrospective cohort study utilizing the Nationwide Inpatient Sample from 2016-2020 included adult patients with PE. The use of ITs (mechanical thrombectomy and catheter-directed thrombolysis) was identified via International Classification of Diseases 10th revision codes. Early IT was defined as procedure performed within the first 2 days after admission.

RESULTS

A total of 27 805 273 records from the 2016-2020 Nationwide Inpatient Sample database were examined. There were 387 514 (1.4%) patients with PE, with 14 249 (3.6%) of them having undergone IT procedures (11 115 catheter-directed thrombolysis, 2314 thrombectomy, and 780 both procedures). After multivariate adjustment, factors associated with less use of IT included Black race (odds ratio [OR], 0.90; 95% CI, 0.86-0.94; P < .01), Hispanic race (OR, 0.73; 95% CI, 0.68-0.79; P < .01), female sex (OR, 0.88; 95% CI, 0.85-0.91; P < .01), treatment in a rural hospital (OR, 0.49; 95% CI, 0.44-0.54; P < .01), and lack of private insurance (Medicare OR, 0.77; 95% CI, 0.73-0.80; P < .01; Medicaid OR, 0.65; 95% CI, 0.61-0.69; P < .01; no coverage OR, 0.87; 95% CI, 0.82-0.93; P < .01). Among the patients who received IT, 11 315 (79%) procedures were conducted within 2 days of admission and 2934 (21%) were delayed. Factors associated with delayed procedures included Black race (OR, 1.12; 95% CI, 1.01-1.26; P = .04), Hispanic race (OR, 1.52; 95% CI, 1.28-1.80; P < .01), weekend admission (OR, 1.37; 95% CI, 1.25-1.51; P < .01), Medicare coverage (OR, 1.24; 95% CI, 1.10-1.40; P < .01), and Medicaid coverage (OR, 1.29; 95% CI, 1.12-1.49; P < .01).

CONCLUSION

Significant racial, sex-based, and geographic barriers exist in overall access to IT for PE in the United States.

Association of race, ethnicity and insurance status with outcomes for patients with acute pulmonary embolism treated by PERT: a retrospective observational study

BACKGROUND

Management of PE has become streamlined with the implementation of PE Response Teams (PERT). Race, ethnicity and insurance status are known to influence the outcomes of patients with acute PE. However, whether the implementation of PERT-based care mitigates these racial and ethnic disparities remains unknown. Our aim was to assess the association of race, ethnicity and insurance with outcomes for patients with acute PE managed by PERT.

METHODS

We performed a retrospective chart review of 290 patients with acute PE, who were admitted to one of three urban teaching hospitals in the Mount Sinai Health System (New York, NY) from January 2021 to October 2023. A propensity score-weighted analysis was performed to explore the association of race, ethnicity and insurance status with overall outcomes.

RESULTS

Median age of included patients was 65.5 years and 149 (51.4%) were female. White, Black and Asian patients constituted 56.2% (163), 39.6% (115) and 3.5% [10] of the cohort respectively. Patients of Hispanic or Latino ethnicity accounted for 8.3% [24] of the sample. The 30-day rates of mortality, major bleeding and 30-day re-admission were 10.3%, 2.1% and 12.8% respectively. Black patients had higher odds of major bleeding (odds ratio [OR]: 1.445; p < 0.0001) when compared to White patients. Patients of Hispanic or Latino ethnicity had lower odds of receiving catheter-directed thrombolysis (OR: 0.966; p = 0.0003) and catheter-directed or surgical embolectomy (OR: 0.906; p < 0.0001) when compared to non-Hispanic/Latino patients. Uninsured patients had higher odds of receiving systemic thrombolysis (OR: 1.034; p = 0.0008) and catheter-directed thrombolysis (OR: 1.059; p < 0.0001), and lower odds of receiving catheter-directed or surgical embolectomy (OR: 0.956; p = 0.015) when compared to insured patients, although the odds of 30-day mortality and 30-day major bleeding were not significantly different.

CONCLUSION

Within a cohort of PE patients managed by PERT, there were significant associations between race, ethnicity and overall outcomes. Hispanic or Latino ethnicity and uninsured status were associated with lower odds of receiving catheter-directed or surgical embolectomy. These results suggest that disparities related to ethnicity and insurance status persist despite PERT-based care of patients with acute PE.

Venous thromboembolism in Black COVID-19 patients in a minority context compared to White, Asian and other racialized patients: A systematic review and meta-analysis

IMPORTANCE

COVID-19 has disproportionately affected racialized populations, with particular impact among individuals of Black individuals. However, it is unclear whether disparities in venous thromboembolic (VTE) complications exist between Black individuals and those belonging to other racial groups with confirmed SARS-CoV2 infections.

OBJECTIVE

To summarize the prevalence and moderators associated with VTE among Black COVID-19 patients in minoritized settings, and to compare this to White and Asian COVID-19 patients according to sex, age, and comorbid health conditions (heart failure, cancer, obesity, hypertension).

DESIGN SETTING, AND PARTICIPANTS

A systematic search of MEDLINE, Embase, CINAHL and CENTRAL for articles or reports published from inception to February 15, 2023.

STUDY SELECTION

Reports on VTE among Black individuals infected with SARS-CoV2, in countries where Black people are considered a minority population group.

DATA EXTRACTION AND SYNTHESIS

Study characteristics and results of eligible studies were independently extracted by 2 pairs of reviewers. VTE prevalence was extracted, and risk of bias was assessed. Prevalence estimates of VTE prevalence among Black individuals with COVID19 in each study were pooled. Where studies provided race-stratified VTE prevalence among COVID19 patients, odds ratios were generated using a random-effects model.

MAIN OUTCOMES AND MEASURES

Prevalence of VTE, comprising of deep vein thrombosis and pulmonary embolism.

RESULTS

Ten studies with 66,185 Black individuals reporting the prevalence of COVID-19 associated VTE were included. Weighted median age of included studies was 47.60. Pooled prevalence of COVID-19 associated VTE was 7.2 % (95 % CI, 3.8 % - 11.5 %) among Black individuals. Among individuals with SARS-CoV2 infections, Black population had higher risks of VTE compared to their White (OR = 1.79, [95 % CI 1.28-2.53], p < .001) or Asian (OR = 2.01, [95 % CI, 1.14-3.60], p = .017) counterparts, or patients with other racial identities (OR = 2.01, [95 % CI, 1.39, 2.92]; p < .001).

CONCLUSIONS AND RELEVANCE

Black individuals with COVID-19 had substantially higher risk of VTE compared to White or Asian individuals. Given racial disparities in thrombotic disease burden related to COVID-19, medical education, research, and health policy interventions are direly needed to ensure adequate disease awareness among Black individuals, to facilitate appropriate diagnosis and treatment among Black patients with suspected and confirmed VTE, and to advocate for culturally safe VTE prevention strategies, including pre-existing inequalities to the COVID-19 pandemic that persist after the crisis.

Trends of Pulmonary Embolism-Related Sudden Cardiac Death in the United States, 1999-2019

OBJECTIVES

Up-to-date population-based data on pulmonary embolism (PE)-related sudden cardiac death (SCD) mortality trends in the United States (US) are scant. We assess the current trends in PE-related SCD mortality in US over the past two decades and determine differences by sex, race, ethnicity, age, and census region.

METHODS

We extracted PE-related SCD mortality rates from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database from 1999 to 2019, in patients aged ≥ 15 years old. Age-adjusted mortality rates (AAMRs) were assessed using the Joinpoint regression modeling and expressed as estimated average annual percentage change (AAPC) with relative 95% confidence intervals (CIs).

RESULTS

Between 1999 and 2019, the AAMR from acute PE-related SCD mortality in the US linearly increased [AAPC: +2.4% (95% CI: 2.2 to 2.6), p < 0.001)]. The AAMR increase was more pronounced in men [AAPC: +2.8% (95% CI: 2.6 to 2.9), p < 0.001], Whites [AAPC: +2.7% (95% CI: 2.3 to 3.1), p < 0.001], Latinx/Hispanic patients [AAPC:+2.0% (95% CI: 1.2 to 2.8), p < 0.001], subjects younger than 65 years [AAPC: +2.4% (95% CI: 2.1 to 2.6), p < 0.001] and in residents of rural areas [AAPC: +3.6% (95% CI: 3.3 to 3.9), p < 0.001]. Moreover, higher percentages of PE-related SCD and the relative absolute number of deaths were observed in the South compared with other geographical regions.

CONCLUSIONS

PE-related SCD mortality in the US has increased over the last two decades. Stratification by race, ethnicity, urbanization, and census region demonstrates ethnoracial and regional disparities that require further investigation and remedy.

Addressing the rising trend of high-risk pulmonary embolism mortality: Clinical and research priorities

BACKGROUND

Deaths from high-risk pulmonary embolism (PE) appear to have increased in the US over the last decade. Modifiable risks contributing to this worrisome trend present opportunities for physicians, researchers, and healthcare policymakers to improve care.

METHODS

We sought to contextualize contemporary, high-risk PE epidemiology and examine clinical trials, quality improvement opportunities, and healthcare policy initiatives directed at reducing mortality.

RESULTS

We observed significant and modifiable excess mortality due to high-risk PE. We identified several opportunities to improve care including: (1) rapid translation of forthcoming data on reperfusion strategies into clinical practice; (2) improved risk stratification tools; (3) quality improvement initiatives to address presumptive anticoagulation practice gaps; and (3) adoption of health policy initiatives to establish pulmonary embolism response teams and address the social determinants of health.

CONCLUSION

Addressing knowledge and practice gaps in intermediate and high-risk PE management must be prioritized and informed by forthcoming high-quality data. Implementation efforts are needed to improve acute PE management and resolve treatment disparities.

Rural-urban differences in pulmonary embolism mortality by race-ethnicity and sex in the United States, 1999-2020

INTRODUCTION

Racial and ethnic differences in pulmonary embolism (PE) mortality within rural and urban regions in the U.S. have not previously been described. PE mortality may vary across regions and urbanization given disparities in social and structural determinants and comorbid disease.

METHODS

Using surveillance data from the Centers for Disease Control and Prevention, age-adjusted mortality rates (AAMR) related to PE were calculated for rural and urban regions in the U.S., in non-Hispanic Black and White women and men, between 1999 and 2020.

RESULTS

Among 137,946 deaths in urban regions and 41,333 deaths in rural regions due to PE during this period, AAMR decreased 1.8% per year in urban regions from 3.1 to 100,000 in 1999 to 2.2 per 100,000 in 2020, and decreased 1% per year in rural regions from 4.3 to 100,000 in 1999 to 3.3 per 100,000 in 2020. Since 2008, AAMR from PE increased in non-Hispanic White males in rural and urban regions, decreased in non-Hispanic Black females in rural regions, and otherwise remained stagnant in all other race-sex groups.

CONCLUSIONS

AAMR from PE was higher in rural compared with urban individuals, with differences by race and sex. Mortality rates remained stagnant over the last decade in non-Hispanic Black adults and non-Hispanic White females and increased in non-Hispanic White males.

Trends in Pulmonary Embolism Deaths Among Young Adults Aged 25 to 44 Years in the United States, 1999 to 2019

A concerning increase in mortality from acute pulmonary embolism (PE) in young adults in the United States has been reported. We extracted PE-related mortality rates (number of deaths per US population) from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database from 1999 to 2019, focusing on subjects aged 25 to 44 years. Age-adjusted mortality rates (AAMRs) were assessed using the Joinpoint regression modeling and expressed as the estimated average annual percentage change (AAPC) with relative 95% confidence intervals (95% CIs) and stratified by urbanization, gender, age, and race. Between 1999 and 2019, the AAMR from acute PE in US adults aged 25 to 44 years linearly increased without any difference between genders (AAPC +1.5%, 95% CI 1.2 to 1.8, p <0.001). AAMR increase was more pronounced in American-Indians/Alaska Natives and in Asian/Pacific Islanders (AAPC +2.5%, 95% CI 1.6 to 3.4, p <0.001), Whites (AAPC +1.7%, 95% CI 1.4 to 2.0, p <0.001), Latinx/Hispanic patients (AAPC +1.7%, 95% CI 0.6 to 3.0, p = 0.003), and residents of rural areas (AAPC +2.4%, 95% CI 1.9 to 2.8, p <0.001). A higher AAMR (4.02 per 100,000 residents, 95% CI 3.90 to 4.15) and absolute number of PE-related deaths were observed in the South. PE-related mortality in adults aged 25 to 44 years has increased over the last 2 decades in the United States. Stratification by race, ethnicity, urbanization, and census region showed ethnoracial and regional disparities that will require further evaluation and remedy.
