BACKGROUND: Life‐threatening status asthmaticus (SA) requiring intensive care is a major concern given the rising prevalence of asthma. We examined episodes of SA requiring admission to the medical intensive care unit (MICU) of an urban hospital center. METHODOLOGY: The charts of patients admitted to the MICU of an urban hospital center with a diagnosis of SA during the 5‐year period 2002–2006 were reviewed retrospectively. These results were compared with those of a previously published experience at our institution from 1995 to 1999. RESULTS: The medical records of 84 MICU admissions for SA were reviewed. There were 61 women (5 pregnant). The mean age was 44 years. Use of cigarettes or illicit drugs was found in 51% and 30%, respectively. Mechanical ventilation (MV) was required in 76% of admissions. Noninvasive ventilation was used in 10 patients. Neuromuscular blockade (NMB) was needed in 9% of admissions. The highest average PaCO 2 during the first 24 hours was 67 mm Hg. Median duration of MV was 4.4 days. Six patients died, 3 of whom sustained prehospital cardiac arrest. Compared with the patients in the preceding 5‐year period, the more recent patients had greater use of illicit drug and cigarettes. Patients presented with more severe asthma, as reflected by a higher PaCO 2 and an increased duration of MV. CONCLUSIONS: During the recent 5‐year period, we found a trend toward increasing severity of SA, as indicated by the degree of respiratory acidosis, need for NMB, and longer duration of MV. Access to medical care and cigarette and illicit drug use remain potential targets of primary intervention. Journal of Hospital Medicine 2008;3:206–211. © 2008 Society of Hospital Medicine.
