BACKGROUND Youth and adolescents with high-risk asthma have poor medication adherence, limited access to care, and are frequently seen in the acute care setting. OBJECTIVE Our purpose was to design and test the feasibility of using smartphone technology to assess contextual factors that may impact changes in daily adherence and identify new symptom episodes among high risk children with asthma in their home environment. METHODS Children 8-17 years with high risk asthma from two children’s hospitals were eligible for the 2-month study. An App was downloaded on participants’ phones at enrollment. Daily text reminders to complete ecological momentary assessment of asthma symptoms and other contextual factors such as emotional state through the App were sent. Bluetooth inhaler devices were used to measure inhaler use with the ability to review and manually enter data. Acceptability was assessed with surveys, key informant interviews (KII), and frequency of days with asthma data. KII data were used in an iterative design approach to identify challenges, strengths, and maximize use. Generalized linear mixed modelling was used to determine contextual factors associated with changes in daily adherence. RESULTS We enrolled 14 children (8-16 years; 93% of whom were African-American). Over the 2-month study period participants reported coughing (45%), wheezing (25%), chest tightness (17%), and boredom (49%). Controller medication adherence was 30% and increased significantly on days with asthma symptoms or boredom. Data were received on 89% of study days. Surveys and KIIs suggested acceptability. Challenges reported during the study included lost or damaged phones and available memory. CONCLUSIONS Patients and families reported acceptability in using smartphones for real-time asthma monitoring. Overall medication adherence was low but increased significantly on days with reported asthma symptoms or boredom, suggesting contextual factors may be associated with a change in adherence behavior.
