School-based Asthma Therapy: Stage 2 Effectiveness Study (SBAT)

July 25, 2014 updated by: Jill Halterman, University of Rochester

School-Based Asthma Therapy: Stage 2 Effectiveness Study

Asthma is the most common chronic illness of childhood, and hospitalization rates are increasing. In the US, impoverished children and children from minority ethnic and racial backgrounds suffer disproportionately from asthma. While National Heart, Lung, and Blood Institute (NHLBI) guidelines recommend daily preventive medications for all children with mild persistent to severe persistent asthma, studies indicate that many children in the US who should receive preventive medications are not receiving them. The overall goal of this project is to target an ethnically diverse population of inner-city schoolchildren with asthma and explore a school-based program to reduce asthma morbidity. We hypothesize that children receiving a comprehensive school-based intervention will experience less asthma-related morbidity compared to children receiving usual care. Our comprehensive school-based intervention consists of both administration of recommended preventive asthma medications in school (with dose adjustments according to NHLBI guidelines) and an environmental tobacco smoke (ETS) reduction program in the home for smoke-exposed children. Our secondary hypothesis is that, among the subgroup of smoke-exposed children, those who receive the school-based intervention with ETS reduction will experience less asthma morbidity than those who receive usual care.

Design Details

  • Primary Purpose: Health Services Research
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Usual Care
Usual asthma care
Experimental: School-based Care
The intervention includes directly observed administration of preventive medications in school and a home-based ETS reduction program (for those living with one or more smokers).
Behavioral: School-based Care
The intervention includes directly observed administration of preventive medications in school and a home-based ETS reduction program (for those living with one or more smokers).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Symptom Free Days
Time Frame: Average Symptom Free Days, over 2 weeks, during peak asthma season (November-February)
The primary outcome variable is the average number of symptom free days over 2 weeks assessed during peak asthma season (data collected during November, December, January and February during the school year).
Average Symptom Free Days, over 2 weeks, during peak asthma season (November-February)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cotinine Level
Time Frame: 2 month and approximately 9 month (end of school year) follow-up assessments
To test the effectiveness of the environmental tobacco smoke (ETS) reduction portion of the study, we will compare baseline cotinine values to 2 month (for smoke exposed participants) and final follow-up assessments (for all participants).
2 month and approximately 9 month (end of school year) follow-up assessments
Cost Effectiveness of the Intervention
Time Frame: approximately 9 months (length of school year)
Cost-effectiveness will examine the net program costs to the number of symptom-free days gained. Benefits will be described as the net difference in medical and productivity costs between children in the treatment and control groups.
approximately 9 months (length of school year)
Additional Asthma Morbidity Outcomes
Time Frame: 1-9 months (Monthly Follow-up assessments)
We will look at additional asthma morbidity outcomes including symptom nights, days needing rescue medications, functional severity, days absent from school, and quality of life.
1-9 months (Monthly Follow-up assessments)
