title: Critical pathway for the emergency department management of acute asthma: effect on resource utilization.
abstract: OBJECTIVE
  To determine the effect of a critical pathway on resource utilization in asthmatic patients.
  
  
  METHODS
  The study combined a prospective analysis of 149 patients with asthma treated by a pathway protocol with a retrospective analysis of 97 patients with asthma treated by conventional means. The setting was a community hospital.
  
  
  RESULTS
  Among patients treated by protocol, oxygen use declined by 19% (P = .001), handheld nebulizer treatments by 33% (P = .001), saline locks by 15% (P = .011), and intravenous steroid administration by 13% (P = .034). There was an increase in the use of metered-dose inhalers with spacer by 64% (P = .001) and oral steroids by 18% (P = .027).
  
  
  CONCLUSIONS
  A critical pathway, based primarily on national guidelines, can be an effective means of treating asthma patients in terms of resource utilization.
