Data from studies using the factor analysis technique have shown that asthma appears to be multidimensional and that most of the subjective and objective measures utilized in the assessment of asthma patients represent a much smaller number of underlying dimensions. Additionally, several investigators have emphasized that evaluation of acute asthma is an ongoing process, as the degree and time course of the response to therapy vary considerably between patients. The aim of this study was to examine the usefulness of the most common clinical and objective measures in the evaluation of acute asthma in the emergency department (ED) for predicting the outcome of acute episodes in adults. ⋯ The validation sample index sensitivity, specificity, and positive and negative predictive values were 0.83, 0.97, 0.83, and 0.97, respectively. In conclusion, a predictive index has been developed for evaluating patients with asthma who present to an ED. This simple and brief three-item index can facilitate an early decision (30 minutes of treatment) to hospitalize patients with severe asthma.
