The investigators have developed a tool to facilitate asthma self-management in children, the electronic-AsthmaTracker (e-AT). The e-AT changes ambulatory asthma care delivery to a new model that is continuous and proactive, focusing on prevention and control, rather than reactive and focusing on management of asthma attacks. The e-AT 1) engages parents in weekly monitoring of their child's chronic asthma symptoms, 2) guides parents to recognize warning signs of asthma attacks in order to prompt appropriate interventions and timely visits to Primary Care Providers, and 3) provides Primary Care Providers with real-time, objective patient data to assess the effectiveness of asthma therapy and prompt adjustments. In a preliminary study of the paper-based version of the AT, frequent users had significantly fewer emergency department (ED) and hospital visits. Parent comments during the e-AT pilot testing revealed that the tool was useful in helping them manage their child's asthma and were interested in assessing the tool's effectiveness and in identifying and addressing barriers to their sustained use of the e-AT.
