Effectiveness and Cost Study Comparing Two Ways to Deliver Albuterol for the Treatment of Asthma in the Hospital

This study has been completed.

This study will be conducted as a randomized, double blinded, controlled trial. The control group will receive albuterol delivered by a nebulizer along with placebo treatments delivered by a metered dose inhaler (MDI) with a spacer +/- mask. The experimental group will receive albuterol delivered by MDI with spacer +/- mask along with placebo treatments given by a nebulizer. Parents, participants, study personnel, nursing staff, and respiratory therapists will not know the treatment assignments of participants. The primary outcome will be changes over time in an asthma severity score, the Clinical Asthma Score (CAS) (Parkin et al. 1996). The secondary outcomes will be total number of albuterol treatments received in the hospital, time it take to give treatments, time till subjects' albuterol treatments are given at four hour intervals, and the costs of the two types of treatments. The study hypothesis is that albuterol delivered by metered dose inhaler with spacer is non-inferior to albuterol delivered by nebulizer in the treatment of children hospitalized with moderate to severe asthma exacerbations.

Study Completion Date: April 2012
Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Subjects receive active medication (albuterol) delivered by a Proair metered dose inhaler used with an Opti-chamber and placebo (normal saline solution) by nebulizer aerosol.
Device: Metered Dose Inhaler & Optichamber Advantage Valve Holding Chamber (VHC)
Albuterol is delivered by metered dose inhaler with valved holding chamber. For children less than 6 years of age, a mask is also used.
Active Comparator: 2
Subjects receive active medication (albuterol) delivered by nebulizer and placebo (no medicine) delivered by a demonstrator Placebo metered dose inhaler demonstrator.
Device: Airlife Sidestream High Efficiency Nebulizer
Albuterol is delivered as a mist mixed with normal saline using a nebulizer machine and face mask or mouth piece.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Children 1 to 18 years of age with a known history of asthma being admitted to Akron Children's Hospital general medical floor for the treatment of moderate to severe asthma exacerbations

Exclusion Criteria:

  • Children who have a concurrent pneumonia or bronchiolitis (diagnosed clinically or by chest x-ray)
  • Have a diagnosis of chronic lung disease (ex. cystic fibrosis, bronchopulmonary dysplasia, chronic aspiration)
  • Have cyanotic congenital heart disease, a congenital anomaly of the respiratory tract, or who are tracheostomy or ventilator dependent.
  • Children who are determined by the Emergency Department (ED) or general pediatrics service to need ICU level care on admission will also be excluded.
  • Children will also be excluded if their legal guardian does not speak English as all consent forms will be written and reviewed with guardians in English.
  • Children will also be excluded if their legal guardians disagree on consent to participate, or if a child 9 years or older and their legal guardians disagree on study participation.
