Multisystemic Therapy to Reduce Health Disparities in Adolescents With Asthma

Study Overview
=================
Brief Summary
-----------------
Asthma is a chronic lung disease that inflames and narrows the airways. Symptoms can include recurring periods of wheezing, chest tightness, shortness of breath, and coughing. Minority, inner city teens are at increased risk for complications from the disease, possibly because of poor illness management. The purpose of this study is to test the effectiveness of Multisystemic Therapy (MST)-an intensive, home- and community-based psychotherapy-for improving asthma management and overall health and for reducing healthcare costs for inner city African American teens with asthma.

Detailed Description
-----------------
Although rates of childhood asthma are increasing worldwide, more alarming is the disproportionate rise in rates of asthma among urban, disadvantaged, minority children. Inner city children, particularly adolescents, also appear to be most at risk for morbidity, mortality, and emergency department visits as a result of asthma. This may be caused by poor illness management. Because of the multiple factors that affect whether or not a family is able to adequately manage a youth's asthma, educational interventions alone are typically insufficient to reduce morbidity and healthcare utilization, particularly in high-risk urban populations. As a result, more intensive, multi-component interventions are necessary to improve asthma management and outcomes for those youth at highest risk. MST is an innovative, flexible, home- and community-based family therapy that has been shown to improve health outcomes in urban children and adolescents with other chronic medical conditions such as type 1 diabetes and HIV infection. The purpose of this study is to determine the effectiveness of MST in improving health outcomes and reducing healthcare costs in high-risk urban adolescents with moderate to severe persistent asthma. Participants will include high-risk African-American adolescents with moderate to severe asthma. High-risk youth are defined as those with one or more hospitalizations for asthma treatment in the previous 12 months. At a baseline hospital visit, participants will complete questionnaires and an interview, both of which will focus on the participant's family and asthma history. Participants will also have the option of having the study personnel visit their home instead. Participants will then be randomly assigned to receive either MST plus standard multidisciplinary specialty care or standard multidisciplinary care alone. Participants assigned to MST will attend psychological treatment sessions in their homes for about 6 months. Treatment sessions will be attended by both children and parents, occur at a time designated by the participants, and last about 1 hour. Participants will also complete questionnaires about their interactions with the therapist and their satisfaction with treatment. Participants assigned to standard multidisciplinary specialty care alone will receive weekly home-based, supportive family counseling for about 6 months. The treatment will provide emotional support to the family regarding asthma, help the family spot problems in asthma care, and address specific support that may help them with asthma management. Counseling sessions will last about 45 minutes. Participants in both groups will receive treatment for 6 months and follow-up for 12 months. Participants will be evaluated at baseline and after 7 and 12 months. Families will also be contacted during Months 3 and 9 for medical information. During the study, the medical charts of participants with asthma will be reviewed for medical history and clinic visits. Other medical providers who directly care for the participant's asthma (e.g., primary care provider) may also be contacted. At the Month 6 evaluation, height and weight measurements will be taken. The study completion date listed in this record was obtained from the Completed Date entered in the Query View Report System (QVR).
