Abdelkarim H, et al. - Among patients admitted with critical asthma syndrome (CAS) to ICUs, researchers compared characteristics, use of invasive ventilation and outcomes between those admitted in Australia and New Zealand (ANZ), and in the United States (US). Utilizing relevant information from two large databases of ICU for patients admitted with CAS in 2014 and 2015, predictive models were derived. In the ANZ and US databases, a total of 2202 and 762 patients admitted with a primary diagnosis of CAS were analyzed, respectively. According to the findings, patients admitted to ANZ and USA ICU with CAS are broadly similar. A low and similar rate of invasive ventilation and mortality were observed among patients admitted to ANZ and USA ICU with CAS. ANZ patients constituted a greater proportion of ICU patients and were found to have longer ICU and hospital stays.
