Clinical studyPulmonary thromboembolism in Asians/Pacific Islanders in the United States: analysis of data from the National Hospital Discharge Survey and the United States Bureau of the Census
Section snippets
Data sources
The number of patients discharged from hospitals with a diagnostic code of pulmonary embolism or deep venous thrombosis was obtained from the National Hospital Discharge Survey (23), which is based on data abstracted from a national probability sample of discharges from short-stay nonfederal hospitals in 50 states and the District of Columbia. From 1990 through 1999, data were obtained annually from 235,000 to 307,000 sampled patient abstracts from 458 to 494 hospitals (23). About 8% of
Results
Age-adjusted rates of diagnosis of deep venous thrombosis during the 10-year observation period were lower in Asians/Pacific Islanders than in African Americans and whites (Table 1; Figure 1). Rate ratios were 0.97 (95% confidence interval [CI]: 0.92 to 0.99) comparing whites with African Americans, 0.21 (95% CI: 0.14 to 0.30) comparing Asians/Pacific Islanders with whites, and 0.20 (95% CI: 0.13 to 0.29) comparing Asians/Pacific Islanders with African Americans. In age groups 20 to 49 years,
Discussion
We found that the rate of deep venous thrombosis, pulmonary embolism, and venous thromboembolism; the incidence in hospitalized patients; and mortality rate from pulmonary embolism were all lower in Asians/Pacific Islanders than in whites and African Americans. Rate ratios showed markedly lower values in Asians/Pacific Islanders.
Klatsky et al (12) reported even lower rates of diagnosis of venous thromboembolic disease among Asian Americans, whites, and African Americans in California. The

2021, American Journal of Emergency MedicineCitation Excerpt :Two of included studies only included patients who required the admission to the intensive care unit [19,37]. We also recognized the potential for heterogeneity between studies conducted on Asian populations versus non-Asian populations as previous studies have shown a lower prevalence of VTE and PE among Asian Americans in the general population regardless of the presence of COPD [10,11]. Asians are also known to require lower doses of warfarin [10,12], suggesting that they may possess antithrombotic traits.
