The emergency department (ED) has emerged as the primary portal for entry to the hospital for most patients with acute health care problems and acute manifestations of underlying chronic diseases, including hypertension 1. Further research is needed to better understand this disparity. Blacks and Hispanics appear less likely to be admitted to the hospital from the ED at a given level of blood pressure even after accounting for triage severity, and other individual and hospital level factors. Conclusions: The relationship between BP and hospital admission is complicated. Whites were substantially more likely to be admitted compared to Blacks and Hispanics at odds ratio 1.5. In the final adjusted model accounting for confounders, we found that the relationship between BP and admission was no longer significant 0.96. We found the odds ratio for admission was 1.11 for each 10 mmHg rise in systolic blood pressure in the unadjusted analysis. We included the range of systolic blood pressure from 110 to 180 mmHg based on the linear relationship with probability of admission. Results: Just over 21,000 visits were included in the study, representing approximately 1.4 million U.S. All analyses were conducted with relevant SURVEY functions in SAS to account for design. We then fit logistic regression models that adjusted for other potential confounders including patient-, visit-, and hospital-level factors. We plotted probability of admission by blood pressure stratified by race/ethnicity to assess for a linear relationship. Methods: We used data from the 2014 National Hospital Ambulatory Medical Care Survey, a representative sample of non-federal, U.S. Our objective was to estimate how the likelihood of hospital admission based on blood pressure (BP) was modified by race/ethnicity. Disparities may exist in access to hospitalization across race/ethnicity.

Hypertension is the most important risk factor for heart disease. Background: The emergency department (ED) has emerged as the primary portal for entry to the hospital for most patients with health care problems, including hypertension.
