The primary aims are to test whether an asthma care management system (M-CHESS) delivered via a smartphone (cellular phone with internet access) can support low income teenagers (ages 12-18) with significant asthma and can improve asthma control and reduce asthma-related emergency or urgent care visits and hospitalizations. Secondary aims include whether M-CHESS increases adherence to asthma control medication and reduces absenteeism from school, work or an event they wanted to attend.

Arms Assigned Interventions
Experimental: M CHESS group
The intervention group will receive access for 12 months to M-CHESS via a smartphone to: (1) contact their case managers and primary provider; (2) communicate with the managed care organization case managers; (3) communicate with peers; (4) share information about changes in health status; (5) receive reminders to take medications and complete medical follow-up; (6) receive feedback on use of their asthma action plan; (7) receive tailored inquiries and insights regarding attendance or use of asthma resources; and (8) access audio and video versions of asthma educational materials and lower reading level versions of text materials; (9) provide monthly study outcome data monthly for 12 months.
Behavioral: M CHESS
Smartphone with access to MCHESS, an asthma control system that provides easy-to-access, just-in-time information and support.
Active Comparator: Control group
The control group will receive standard care plus a smartphone for 12 months; they will provide study outcome data monthly for the next 12 months.

Detailed Description:

Four hundred Milwaukee Medicaid recipients (ages 12-18), with an asthma-related emergency care visit or hospitalization in the last twelve months, will be recruited through their managed care organization (MCO). They will be randomly assigned to one of two study arms and will participate in a 12-month intervention plus a 12-month follow-up period. Subjects in the control group will receive a smartphone with internet access & text messaging service. These devices will provide the ability to collect smartphone use data electronically. The experimental group will also receive the same smartphone devices (with internet access and text messaging service and ability to collect usedata. In addition the experimental group will have access to the Mobile CHESS (M-CHESS) interface. The M-CHESS smartphone interface features an interactive, internet based asthma education program, peer support mechanisms and automated reminders for asthma control medicines and data collection.
