A prospective evaluation of the 1-hour decision point for admission versus discharge in acute asthma
2003
Study objectives were to evaluate the 1-hour decision point for discharge or admission for acute asthma; to compare this decision point to the admission recommendations of the Expert Panel Report 2 (EPR-2) guidelines; to develop a model for predicting need for admission in acute asthma. The design used was a prospective preinterventional and postinterventional comparison. The setting was a university hospital emergency department. Participants included 50 patients seeking care for acute asthma. Patients received standard therapy and were randomized to receive albuterol by nebulizer or metered-dose inhaler with spacer every 20 minutes up to 2 hours. Symptoms, physical examination, spirometry, pulsus paradoxus, medication use, and outcome were evaluated. Based on clinical judgment, the attending physician decided to admit or discharge after 1 hour of therapy. Outcome was compared to the EPR-2 guidelines. Post hoc statistical analyses examined predictors of the need for admission from which a prediction mode...
