title: A randomized trial of home oxygen therapy from the emergency department for acute bronchiolitis.
abstract: OBJECTIVE
  Hypoxia is a common reason for hospital admission in infants and children with acute bronchiolitis. No study has evaluated discharge from the emergency department (ED) on home oxygen. This study evaluated the feasibility and safety of ED discharge on home oxygen in the treatment of acute bronchiolitis.
  
  
  METHODS
  This was a prospective, randomized trial of infants and children with acute bronchiolitis and hypoxia (room-air saturations of < or =87%) aged 2 to 24 months presenting to an urban, academic, tertiary care children's hospital ED from December 1998 to April 2001. Subjects received inpatient admission or home oxygen after an 8-hour observation period in the ED. We measured the failure to meet discharge criteria during the observation period, return for hospital admission, and incidence of serious complications.
  
  
  RESULTS
  Ninety-two patients were enrolled. Fifty three (58%) were randomly assigned to home and 39 (42%) to inpatient admission. There were no differences between the groups in age, initial room-air saturation, and respiratory distress severity score. Of 53 patients, 37 (70%) randomly assigned to home oxygen completed the observation period and were discharged from the hospital. The remaining 16 patients were excluded from the study (6), resolved their oxygen requirement (5), or failed to meet the discharge criteria and were admitted (5). One discharged patient (2.7%) returned to the hospital and was admitted for a cyanotic spell at home after the 24-hour follow-up appointment. The patient had an uncomplicated hospital course with a length of stay of 45 hours. The remaining 36 patients (97%) were treated successfully as outpatients with home oxygen. Satisfaction with home oxygen was high from the caregiver and the primary care provider.
  
  
  CONCLUSIONS
  Discharge from the ED on home oxygen after a period of observation is an option for patients with acute bronchiolitis. Secondary to the low incidence of complications, the safety of this practice will require a larger study.
