Asthma Controller Adherence After Hospitalization

Subjects in the intervention arm will receive once daily text messages at the time of their choice or at a default time of 7am. The text message will remind them to give their child their controller medication and provide a helpful information on asthma controller use.

An electronic monitor will be affixed to subjects' inhaled steroid canister and families will be instructed to use the inhaler as directed by their physician. Subjects will not receive daily text messages.The canister monitor, the Propeller sensor (Propeller, Madison, Wisconsin) is an FDA-approved, portable device which affixes to the top of most metered dose inhaler canisters. The devices records the number and time of each inhaler actuation and transmits this information to either a smart phone or cellular modem. Data is then sent via the cellular network to the secure Propeller server. The data will then be downloaded monthly.
