Section snippets
Materials and Methods
We analyzed data from three prospective cohort studies performed from 1996 to 1998 as part of the MARC (http://healthcare.partners.org/marc). The purpose of the MARC was to try to define the characteristics of patients presenting to the ED for acute asthma, to describe their management and outcome, and to follow their course after hospital discharge. Using a standardized protocol, researchers at 64 EDs in 21 US states and 4 Canadian provinces provided 24-h coverage for a median duration of 2
Results
Among the eligible patients, 588 refused study entry, were missed, or were not enrolled for another reason, and 1,847 were enrolled into the study. Three patients were excluded because race/ethnicity data were missing. Patients identified as Asian or “other” race/ethnicity (44 patients) were excluded, since the purpose of the study was to investigate blacks and Hispanics. Patients who were enrolled did not differ from those who were not enrolled according to demographic factors, available
Discussion
It is widely recognized that black and Hispanic asthma patients receive substandard outpatient care, visit the ED more frequently, and are hospitalized at greater rates than are whites.8,9,10,11,12,13,14,15,16,17,18,48 However, little is known about whether racial/ethnic differences exist during the course and treatment of exacerbations while in the ED or whether racial/ethnic differences exist in relapse and outcome after discharge from the ED. Because we prospectively enrolled patients during

2021, Contemporary Clinical TrialsCitation Excerpt :When compared with Caucasians, asthma prevalence is 35% higher in AA/Bs and approximately 100% higher in H/Ls [1,6–8]. When adjusted for prevalence, relative to Caucasians, AA/Bs and H/Ls experience higher rates of asthma-related ED visits and hospitalizations [9–14] and approximately double the death rate [1,15]. The 2007 National Asthma Education and Prevention Program (NAEPP) guidelines recommend regular use of an inhaled corticosteroid (ICS) in all but the mildest cases [16].
