RESUMO
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.

BACKGROUND: Venous thromboembolism (VTE) stands as the leading cause of preventable death within hospitals in the United States. Although there have been some studies investigating the incidence rates of VTE, there has yet to be a large-scale study elucidating disparities in sex, race, income, region, and seasons in patients with VTE. The goal of this study was to report the disparities in race, sex, income, region, and seasons in patients with VTE, pulmonary embolism (PE), and deep vein thrombosis (DVT), in hospitalized patients from 2016 to 2019. METHODS: We used the United States National Inpatients Sample database to identify inpatients diagnosed with PE, DVT, and PE and DVT from 2016 to 2019. The inpatient incidence per thousand was calculated for sex and race using the weighted sample model. The regional and monthly incidence of DVT and PE per thousand inpatients and risk of incidence were calculated. Patients' characteristics including hospital type, bed size, median length of stay, median total charges, and mortality were also collected. RESULTS: We examined 455,111 cases of VTE, 177,410 cases of DVT, 189,271 cases of PE, and 88,430 cases of both DVT and PE combined. Over the study period, we observed a statistically significant trend among PE hospitalization incidences. There was a strong and positive correlation between DVT and PE inpatients. Black inpatients had the highest cumulative incidence of hospitalizations in all cohorts with 10.36 per 1000 in PE and 9.1 per 1000 in DVT. Asian and Pacific Islander inpatients had the lowest cumulative incidence with 4.42 per 1000 in PE and 4.28 per 1000 in DVT. Females showed the lowest cumulative incidence with 7.47 per 1000 in PE and 6.53 per 1000 in DVT. The Mountain region was the highest among PE hospitalizations with 9.62 per 1000. For DVT, the Middle Atlantic region was the highest at 8.65 per 1000. The in-hospital mortality rate was the highest among the PE hospitalizations at 7.3%. Also, the trend analysis showed significant increases among all groups. CONCLUSIONS: Over the study period (2016-2019), we report the racial, biological sex, and geographical disparities from the National Inpatient Sample database, highlighting that Black inpatients had the highest incidence of PE and DVT, whereas Asian/Pacific Islander inpatients had the lowest incidences of PE and DVT. Moreover, women had a lower incidence compared with men. The observed regional variations indicated that the incidence of PE was highest in the Mountain region, whereas the incidence of DVT was lowest in the Middle Atlantic region. There was an increase in the mortality of inpatients diagnosed with VTE reflecting the growing burden of this condition in the US health care system.

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.

BACKGROUND: Population-based data on high-risk pulmonary embolism (PE) mortality trends in the United States (US) are scant. OBJECTIVES: To assess current trends in US mortality related to high-risk PE over the past 21 years and determine differences by sex, race, ethnicity, age and census region. METHODS: Data were extracted from the Centers for Disease Control and Prevention (CDC) Wide-ranging ONline Data for Epidemiologic Research (WONDER) to determine trends in age-adjusted mortality rates (AAMR) per 100,000 people, due to high-risk PE. To calculate nationwide annual trends, we assessed the average (AAPC) and annual percent change (APC) with relative 95 % confidence intervals (CIs) using Joinpoint regression. RESULTS: Between 1999 and 2019, high-risk PE was listed as the underlying cause of death in 209,642 patients, corresponding to an AAMR of 3.01 per 100,000 people (95 % CI: 2.99 to 3.02). AAMR from high-risk PE remained stable from 1999 to 2007 [APC: -0.2 %, (95 % CI: -2.0 to 0.5, p = 0.22)] and then significantly increased [APC: 3.1 % (95 % CI: 2.6 to 3.6), p < 0.0001], especially in males [AAPC: 1.9 % (95 % CI: 1.4 to 2.4), p < 0.001 vs AAPC: 1.5 % (95 % CI: 1.1 to 2.2), p < 0.001]. AAMR increase was more pronounced in those <65 years, Black Americans, and residents of rural areas. CONCLUSIONS: In an US population analysis, high-risk PE mortality rate increased, with racial, sex-based, and regional variations. Further studies are needed to understand root causes for these trends and to implement appropriate corrective strategies.

BACKGROUND: A large proportion of pulmonary embolism (PE) heritability remains unexplained, particularly among the East Asian (EAS) population. Our study aims to expand the genetic architecture of PE and reveal more genetic determinants in Han Chinese. METHODS: We conducted the first genome-wide association study (GWAS) of PE in Han Chinese, then performed the GWAS meta-analysis based on the discovery and replication stages. To validate the effect of the risk allele, qPCR and Western blotting experiments were used to investigate possible changes in gene expression. Mendelian randomization (MR) analysis was employed to implicate pathogenic mechanisms, and a polygenic risk score (PRS) for PE risk prediction was generated. RESULTS: After meta-analysis of the discovery dataset (622 cases, 8853 controls) and replication dataset (646 cases, 8810 controls), GWAS identified 3 independent loci associated with PE, including the reported loci FGG rs2066865 (p-value = 3.81 × 10-14), ABO rs582094 (p-value = 1.16 × 10-10) and newly reported locus FABP2 rs1799883 (p-value = 7.59 × 10-17). Previously reported 10 variants were successfully replicated in our cohort. Functional experiments confirmed that FABP2-A163G(rs1799883) promoted the transcription and protein expression of FABP2. Meanwhile, MR analysis revealed that high LDL-C and TC levels were associated with an increased risk of PE. Individuals with the top 10% of PRS had over a fivefold increased risk for PE compared to the general population. CONCLUSIONS: We identified FABP2, related to the transport of long-chain fatty acids, contributing to the risk of PE and provided more evidence for the essential role of metabolic pathways in PE development.

Venous thromboembolism (VTE) comprising deep venous thrombosis and pulmonary embolism is a major cause of morbidity and mortality. Short-term immobility-related conditions are a major risk factor for the development of VTE. Paradoxically, long-term immobilized free-ranging hibernating brown bears and paralyzed spinal cord injury (SCI) patients are protected from VTE. We aimed to identify mechanisms of immobility-associated VTE protection in a cross-species approach. Mass spectrometry-based proteomics revealed an antithrombotic signature in platelets of hibernating brown bears with heat shock protein 47 (HSP47) as the most substantially reduced protein. HSP47 down-regulation or ablation attenuated immune cell activation and neutrophil extracellular trap formation, contributing to thromboprotection in bears, SCI patients, and mice. This cross-species conserved platelet signature may give rise to antithrombotic therapeutics and prognostic markers beyond immobility-associated VTE.

Background Existing evidence indicates Black patients have higher incidence of pulmonary embolism (PE) and PE-related mortality compared with other races/ethnicities, yet disparities in presenting severity and treatment remain incompletely understood. Methods and Results We retrospectively queried a multihospital healthcare system for all hospitalizations for acute PE (2012-2019). Of 10 329 hospitalizations, 8743 met inclusion criteria. Black patients (14.3%) were significantly younger (54.6±17.8 versus 63.1±16.6 years; P<0.001) and more female (56.1% versus 51.6%; P=0.003) compared with White patients. Using ordinal regression, Black race was significantly associated with higher PE severity after matching 1:3 on age and sex (1210:3264; odds ratio [OR], 1.08; 95% CI, 1.03-1.14), adjusting for clinical (OR, 1.13; 95% CI, 1.01-1.27), and socioeconomic (OR, 1.05; 95% CI, 1.05-1.35) characteristics. Among intermediate and high-severity PE, Black race was associated with a decreased risk of intervention controlling for the competing risk of mortality and censoring on hospital discharge. This effect was modified by PE severity (P value <0.001), with a lower and higher risk of intervention for intermediate and high-severity PE, respectively. Race was not associated with in-hospital mortality (OR, 0.84; 95% CI, 0.69-1.02). Conclusions Black patients hospitalized with PE are younger with a higher severity of disease compared with White patients. Although Black patients are less likely to receive an intervention overall, this differed depending on PE severity with higher risk of intervention only for life-threatening PE. This suggests nuanced racial disparities in management of PE and highlights the complexities of healthcare inequalities.

BACKGROUND: There is limited literature identifying racial and ethnic health disparities among surgical modalities and outcomes in the field of urogynecology and specifically pelvic organ prolapse surgery. OBJECTIVE: This study aimed to evaluate the differences in surgical approach for apical vaginal prolapse and postoperative complications by race and ethnicity. STUDY DESIGN: This is a retrospective cohort study of women undergoing surgical repair for apical vaginal prolapse between 2014 and 2017 using data from the American College of Surgeons National Surgical Quality Improvement Program. Patients were eligible for inclusion if they underwent either vaginal colpopexy or abdominal sacrocolpopexy. Abdominal sacrocolpopexy cases were further divided into those performed by laparotomy and those performed by laparoscopy. Multivariable logistic regression models that controlled for age, comorbidities, American Society of Anesthesiologists physical status classification, and concurrent surgery were used to determine whether race and ethnicity are associated with the type of colpopexy (vaginal vs abdominal) or the surgical route of abdominal sacrocolpopexy. Similar models that also controlled for surgical approach were used to assess 30-day complications by race and ethnicity. RESULTS: A total of 22,861 eligible surgical cases were identified, of which 12,337 (54%) were vaginal colpopexy and 10,524 (46%) were abdominal sacrocolpopexy. Among patients who had an abdominal sacrocolpopexy, 2262 (21%) were performed via laparotomy and 8262 (79%) via laparoscopy. The study population was 70% White, 9% Latina, 6% African American, 3% Asian, 0.6% Native Hawaiian or Pacific Islander, 0.4% American Indian or Alaska Native, and 11% unknown. In multivariable analysis, Asian and Native Hawaiian or Pacific Islander women were less likely to undergo abdominal sacrocolpopexy compared with White women (odds ratio, 0.82; 95% confidence interval, 0.68-0.99, and odds ratio, 0.56; 95% confidence interval, 0.39-0.82, respectively). Among women who underwent an abdominal sacrocolpopexy, Latina women and Native Hawaiian or Pacific Islander women were less likely to undergo a laparoscopic approach compared with White women (odds ratio, 0.68; 95% confidence interval, 0.58-0.79, and odds ratio, 0.31; 95% confidence interval, 0.1-0.56, respectively). Complication rates also differed by race and ethnicity. After a colpopexy, African American women were more likely to need a blood transfusion (odds ratio, 3.04; 95% confidence interval, 1.95-4.73; P≤.001) and have a deep vein thrombosis or pulmonary embolus (odds ratio, 2.46; 95% confidence interval, 1.10-5.48; P=.028), but less likely to present with postoperative urinary tract infections (odds ratio, 0.68; 95% confidence interval, 0.49-0.96; P=.028) than White women in multivariable regression models. Using the Clavien-Dindo classification system, Latina women had higher odds of developing grade II complications than White women in multivariable models (odds ratio, 1.25; 95% confidence interval, 1.04-1.51; P=.02). CONCLUSION: There are racial and ethnic differences in the type and route of surgical repair for apical vaginal prolapse. In particular, Latina and Pacific Islander women were less likely to undergo a laparoscopic approach to abdominal sacrocolpopexy compared with White women. Although complications were uncommon, there were several complications including blood transfusions that were higher among African American and Latina women. Additional studies are needed to better understand and describe associated factors for these differences in care and surgical outcomes.

BACKGROUND: Prophylactic inferior vena cava (IVC) filter use in bariatric surgery patients is a physician- and patient-dependent practice pattern with unclear safety and efficacy. Factors that mediate physicians' decisions for IVC filter placement preoperatively remain unclear. The role of race in decision-making also remains unclear. METHODS: From the 2015-2016 MBASQIP database, patient characteristics leading to IVC filter use and outcomes after IVC filter placement were compared between Black and White primary bariatric surgery patients. RESULTS: Prophylactic IVC filter was used in 0.66% of Black and White patients. IVC filter use was three-fold higher in Black patients, despite this cohort having a lower venous thromboembolism (VTE) risk profile than White counterparts. Black race was an independent predictor for IVC filter placement on multivariate analysis. After receiving an IVC filter, Black patients had higher rates of 30-day adverse outcomes. CONCLUSIONS: In this study, Black race was independently associated with the likelihood of receiving a prophylactic IVC filter, despite lower rates of VTE risk factors and lack of recommendations for its use. Further research is needed to explore why this disparity in clinical practice exists.

BACKGROUND: The G202010A prothrombin gene mutation is a documented prothrombotic risk factor in Caucasian patients. Several other mutations have been described within the prothrombin gene, predominantly in non-Caucasians, including the C20209T mutation. The clinical significance of this mutation is uncertain, but it has been associated with thrombotic events and pregnancy complications. METHODS: We describe a 28-year-old black South African woman who presented with pulmonary embolism during pregnancy. She was investigated for underlying prothrombotic biomarkers. RESULTS: Genetic screening for the prothrombin G202010A mutation by real-time polymerase chain reaction and melting curve analysis demonstrated an atypical mutant peak. Sequencing confirmed a variant C20209T prothrombin mutation. CONCLUSIONS: This is the first report of the C20209T mutation in the Southern African population. It remains uncertain whether genetic testing should be offered routinely to non-Caucasian patients in a resource-limited setting.

PURPOSE: Catheter-directed thrombolysis (CDT) is an emerging, minimally invasive treatment for patients with massive and submassive pulmonary embolism (PE). The value of follow-up pulmonary angiography for evaluating improvement after CDT is limited by a paucity of large studies assessing its utility and role for additional intervention. The purpose of our study was to assess the role of next-day pulmonary angiography for CDT in patients with acute massive and submassive PE undergoing continuous pulmonary arterial pressure monitoring, and secondarily, determine factors that are correlated with a need for further therapy. METHODS: Patients who underwent CDT from 2006 to 2016 for massive and submassive PE were reviewed. Patient demographics, comorbidities, preprocedural lab results, noninvasive hemodynamic studies, and technical variables were recorded. Among patients receiving next-day angiography, those requiring further therapy, defined as continued CDT beyond the standard 24 hours (with or without catheter repositioning or exchange) and/or mechanical or suction thrombectomy were contrasted with those not requiring additional therapy to assess for the role of angiography and patient factors that correlate with need for further therapy. RESULTS: Thirty-two patients underwent CDT for massive (n=14) and submassive (n=18) PE. Eighteen (56.3%) were male, 14 (43.7%) were Caucasian, 18 (56.3%) were African-American, with a mean age of 66.2 years (range, 26-87 years). Of the 27 (84.4%) patients that underwent next-day pulmonary angiography, 16 (59.3%) did not require additional therapy and 11 (40.7%) did require additional therapy. Additional therapy included extended CDT beyond 24 hours (n=4), mechanical/suction thrombectomy (n=5), or both extended CDT and mechanical/suction thrombectomy (n=2). Younger age (50.1 vs. 62.2 years, P = 0.039) was correlated with a need for further therapy. Initial (40.7 vs. 34.8 mmHg, P = 0.248), next-day (31.5 vs. 26.3 mmHg, P = 0.259), and interval change (4.6 vs. 8.0 mmHg, P = 0.669) in pulmonary artery pressures were not statistically significant between patient subsets. Preprocedural right ventricular/left ventricular ratio (RV/LV) also did not differ significantly (1.74 vs. 1.75, P = 0.961). Thirty-day mortality was comparable (2 vs. 1, P = 0.332). CONCLUSION: Next-day pulmonary angiography is a useful method to identify patients needing additional therapy including extended CDT and/or mechanical or suction thrombectomy in acute PE management. Pulmonary arterial pressures and preprocedural RV/LV ratios were not found to be predicative of those requiring further intervention.

Protein S (PS) deficiency is associated with a 10-fold increased risk of venous thromboembolism (VTE), but its diagnosis is quite difficult and complicated. In this study, we identified 53 unrelated pedigrees with PS deficiency in China. Data of their clinical characteristics and laboratory examinations were collected. Genetic analysis of PROS1 including direct sequencing, copy number variant detection and messenger ribonucleic acid analysis was performed in probands and related family members. Of these 53 probands, 52.8% (28/53) experienced multi-site and/or recurrent thrombotic episodes, mainly manifested as deep venous thrombosis and/or pulmonary embolism (82.7%). Additional risk factors of VTE were observed in 39.6% (21/53) probands who exhibited a significantly higher rate of recurrent VTE compared with those not, in which 7 probands were complicated by anti-phospholipid syndrome. Most probands and family members exhibited quantitative PS deficiency with impairment of both activated protein C and tissue factor pathway inhibitor cofactor activities. Note that 87.2% (34/39) PROS1 detectable mutation rate was obtained through comprehensive phenotypic and genetic analysis. A total of 36 PROS1 causative mutations including 16 novel mutations were identified in 48 probands, whereas no PROS1 mutations were detected in the other 5 probands. Three hotspot mutations (Glu67Ala, Arg561Trp and Tyr560*) were identified in the Chinese population for the first time. This article provides a framework for correlating the clinical pathogenesis of PS deficiency to genetic backgrounds in the Chinese population.

We performed this meta-analysis to better assess the relationship between methylenetetrahydrofolate reductase gene ( MTHFR) polymorphisms and the risk of venous thromboembolism. Eligible studies were searched in PubMed, Medline, Embase, and Web of Science. Odds ratios with 95% confidence intervals were used to assess associations of MTHFR polymorphisms with venous thromboembolism. A total of 99 genetic association studies were enrolled for analyses. Although no positive results were detected in overall analyses for the rs1801131 polymorphism. Further subgroup analyses according to ethnicity of participants and type of disease revealed that the rs1801131 polymorphism was significantly correlated with the risk of pulmonary embolism. For the rs1801133 polymorphism, significant association with the risk of venous thromboembolism was found in the dominant, recessive, and allele models. Further subgroup analyses according to ethnicity of participants revealed that the rs1801133 polymorphism was significantly associated with the risk of venous thromboembolism in Caucasians, East Asians, and West Asians. When we stratified available data according to type of disease, we found that the rs1801133 polymorphism was also significantly correlated with the risk of deep vein thrombosis and pulmonary embolism. In conclusion, our findings indicate that the MTHFR rs1801133 polymorphism may serve as a potential biological marker for venous thromboembolism in Caucasians, East Asians, and West Asians. Moreover, the MTHFR rs1801133 polymorphism may be implicated in the development of deep vein thrombosis and pulmonary embolism, while the MTHFR rs1801131 polymorphism may contribute to the development of pulmonary embolism.

Although rare in children, pulmonary embolism (PE) can cause significant morbidity and mortality. Overall rates of venous thromboembolism (VTE) are increasing in hospitalized children. By using the Pediatric Health Information System database, we evaluated incidence, treatment, and outcome of PE in children younger than age 18 years from 2001 to 2014. Demographic characteristics for those admitted with VTE alone and those admitted with PE were compared. Rates of PE by year were compared with the number of hospital and VTE admissions. Trends in medication use were analyzed. Over the period of the study, patients with PE made up 15.8% of VTE discharges. The overall rate of PE increased 200% (P < .001). Compared with all other age groups, adolescents (age 13-18 years) had the highest prevalence (55%; P < .001), the rate of which increased from 9.8 to 24.7 per 10 000 hospital discharges (152%; P < .001), and from 17.5 to 34.1 per 100 VTE discharges (95%; P < .001). Individuals with PE had a higher mortality (8.3% vs 6%; P < .001) and were less likely to have a complex chronic condition (58% vs 65%; P < .001) than those with VTE alone. However, PE mortality rates decreased over the time period studied. African American and Hispanic patients were more likely to experience recurrent PE than white patients (12% and 10.7% vs 8%; P = .002). During the study period, the use of unfractionated heparin decreased (P < .001), and the use of low molecular weight heparin increased (P < .001). Further research is required to determine what factors contribute to the higher rate of PE in adolescents and influence recurrence in African American and Hispanic patients.

Introduction Venous thromboembolism (VTE) remains a major public health issue around the world. Ethnicity is known to alter the incidence of VTE. To our knowledge, there are no reports in the literature investigating the incidence of VTE in British Indians. The aim of this study was to investigate the rates of symptomatic VTE in British Indian patients in the UK. Methods Patients referred to our institution between January 2011 and August 2013 with clinically suspected VTE were eligible for inclusion in the study. Those not of British Indian or Caucasian ethnicity were excluded. A retrospective review of these two cohorts was conducted. Results Overall, 15,529 cases were referred to our institution for suspected VTE. This included 1,498 individuals of British Indian ethnicity. Of these, 182 (12%) had confirmed VTE episodes. A further 13,159 of the patients with suspected VTE were coded as Caucasian, including 2,412 (16%) who had confirmed VTE events. VTE rates were a third lower in British Indians with clinically suspected VTE than in the equivalent Caucasian group. The British Indian cohort presented with VTE at a much earlier age than Caucasians (mean 57.0 vs 68.0 years). Conclusions This study suggests that British Indian patients have a lower incidence of VTE and are more likely to present at an earlier age than Caucasians. There was no significant difference in VTE type (deep vein thrombosis vs pulmonary embolism) among the ethnic groups. Clinicians should be aware of variations within ethnicities but should continue to adhere to existing VTE prevention guidance.

Disparities in the incidence of pulmonary embolism (PE) based on racial and socioeconomic factors remain ill-defined. The present study evaluated the impact of race and hospital characteristics on rates of PE for all adult colectomy patients in the 2005 to 2014 Nationwide Inpatient Sample. Hospitals were designated as high-burden hospitals (HBHs) or low-burden hospitals of underinsured payers. Chi-squared tests of trend and multivariable regression adjusting for patient and hospital characteristics were performed. Of the 2,737,977 adult patients who underwent colectomy in the study period, 79 per cent were White, 10 per cent Black, and 7 per cent Hispanic. The annual rate of PE increased from 0.6 per cent in 2005 to 0.95 per cent in 2014 (P < 0.0001). Black patients had significantly higher incidence of PE than Whites (1.5% vs 0.9%, P < 0.001) and Hispanics (1.5% vs 0.8%, P < 0.001). Colectomy at HBHs was also associated with significantly higher rates of PE (1% vs 0.86%, P < 0.001). After adjusting for baseline differences, colectomy at HBHs (odds ratio 1.14, 95% confidence interval 1.02-1.27, P = 0.02) and Black race (odds ratio 1.4, 95% confidence interval 1.26-1.66, P < 0.001) were independent predictors of PE. In this national study of colectomy patients, Black patients experienced a disproportionate burden of postoperative PE. Further investigation into the causes and prevention of PE in vulnerable populations may identify targets for surgical quality improvement.

BACKGROUND/OBJECTIVE: Deep vein thrombosis (DVT) was thought to be uncommon in Asians and routine thromboprophylaxis in the form of anticoagulation for surgical patients was considered to be unnecessary. The current study aims to provide a contemporary epidemiology of venous thromboembolism in a population-based scale. METHODS: Information from January 1, 2010 to December 31, 2011 was retrieved from a centralized computer public healthcare database serving mainly an ethnic Han Chinese population of 7.1 million. The incidence, demographics, and hospital mortality rates of DVT and pulmonary embolism (PE) were obtained, and analyzed for different surgical categories. RESULTS: The overall annual incidences of DVT, PE alone, and PE with DVT were 30.0 per 100,000 population, 8.7 per 100,000 population, and 3.0 per 100,000 population, respectively. Overall male to female ratio was 1:1.24. Venous thromboembolic disease was more common with increasing age in both sexes. Thirty days' mortality rates associated with DVT, PE alone, and PE with DVT were 9.0%, 17.4%, and 13.3% respectively. Among the patients who received 103,023 major and intermediate surgical procedures in the study period, the mean incidence of postoperative DVT, PE alone, and PE with DVT were only 0.20% (203.5 patients), 0.08% (85.5 patients), and 0.04% (40.5 patients) respectively. CONCLUSION: Compared with a similar study 10 years ago, there seemed to be a general increase in incidence of DVT and PE. This study showed that postoperative thromboembolic events were not uncommon, with DVT occurring in up to 0.2% of patients and PE in 0.12% of patients in this longitudinal survey.
