A retrospective study in an urban, municipal, teaching hospital emergency department (ED) was conducted to evaluate (1) the frequency of asymptomatic hypertension in the ED, (2) the initial assessment and patterns of treatment by physicians, and (3) the changes in blood pressure (BP) in these patients. Patients with systolic BP > or = 180 mm Hg or diastolic BP > or = 110 mm Hg were included. Patients with cardiovascular, renal, or central nervous system dysfunction were excluded. Of the 11,531 charts reviewed, 269 (2.3%) met inclusion criteria. Of the 269 patients, 56 patients (20.8%) received antihypertensive treatment in the ED. The treatment group had a higher systolic BP (P < .001), diastolic BP (P < .001), and mean arterial blood pressure (MAP) (P < .001) than the nontreatment group. Fundoscopy was also performed more frequently in the treatment group (30.2% v 8.9%, P < .001). MAP decreased for both groups in the ED, but was higher in the treatment group (-20+/-21 v -11+/-21 mm Hg, P=.02). Despite the lack of support in the literature for the emergency treatment of asymptomatic hypertension in the ED, the individual physician's decision for treatment correlated with the degree of hypertension. Significantly elevated BP readings in the ED tended to decrease over time independent of any antihypertensive treatment, although the decrease was larger in the treated patients

OBJECTIVE: To determine the prevalence of herbal preparation use among patients presenting to an urban teaching hospital ED. METHODS: A prospective anonymous survey on herbal preparation use was performed. Consecutive, acutely ill or injured adult (> or = 18 years old) ED patients were offered the survey over a 1-month period. The survey also asked for information related to patient age, ethnicity, gender, employment, education, cigarette smoking history, ethanol consumption, use of illicit drugs, chief complaint, and HIV status. RESULTS: Of 2,473 eligible subjects, 623 (25%) participated. The overall reported prevalence of herbal preparation use among the participants was 21.7%. Women were more likely to use herbal preparations than men (28.5% vs 17.2%, p = 0.013). Prevalence rates in different ethnic populations were: whites, 18.2%; Hispanics, 13.9%; blacks, 26.4%; and Asians, 36.8%. Asians had a significantly higher use rate than the other ethnic groups (p = 0.039). Neither HIV positivity, educational level, employment status, nor age was significantly associated with herbal preparation use. The most commonly reported herbal preparations were goldenseal tea, garlic, and ginger. Several of the herbal preparations reported as used by patients in this study have been associated with severe systemic toxicity in the medical literature. CONCLUSION: Although the survey response rate was low, the prevalence of herbal preparation use among acutely ill or injured patients presenting to this urban ED remains significant. A directed history toward specific herbal preparation use may provide relevant pharmacologic information and uncover cases of herbal-preparation-induced toxicity
