Factors Influencing Pediatric Asthma

Study Overview
=================
Brief Summary
-----------------
Asthma is a chronic lung disease with serious morbidity and potential mortality. Multiple physiologic, environmental and social conditions impact the prevalence and severity of asthma. Even when diagnosed, effective control can be impeded by improper use of medication, not understanding or being unable to avoid environmental triggers, lack of continuity in follow-up care, and lack of an asthma action plan. American Indians are especially at-risk for health problems related to asthma. American Indians have the highest asthma rate among single-race groups; 18.5% of American Indians are diagnosed with asthma, while only 11% are diagnosed with asthma in the general population but little is known about why this is true. Asthma is a prototypic example of the interaction of biologic, environmental and psychosocial influences on disease and this study investigated the possible improvement in asthma control from an intensive educational intervention.

Detailed Description
-----------------
The primary aim of this study was to test the hypothesis that intensive patient education regarding self-directed, stepped care will result in reduced morbidity and medical care utilization, while increasing quality of life. One half (54) of the identified cases will be randomized to receive the previously established BREATHE study educational program, emphasizing patient-centered, self management of asthma. Periodic follow-up through personal contact and surveillance of IHS RPMS or other medical provider records was conducted.
