Edward Boyer, MD, PhD, professor of emergency medicine at UMass Medical School and lead author of the study, worked with colleagues at UMMS and at the Massachusetts Institute of Technology, to design a mobile device using so-called "enabling technologies" that could be used to make behavioral interventions for substance abusers more effective outside the clinic or office environments. The result of their work, iHeal, combines sensors to measure physiological changes and detect trigger points for risky health behaviors, such as substance use, with smartphone software tailored to respond with patient-specific interventions.
Individuals with a history of substance abuse and post-traumatic stress disorder were asked to wear an iHeal sensor band around their wrist that measures the electrical activity of the skin, body motion, skin temperature and heart rate - all indicators of stress. The band wirelessly transmits information to a smartphone, where software applications monitor and process the user's physiological data. When the software detects an increased stress level, it asks the user to annotate events by inputting information about their perceived level of stress, drug cravings, and current activities. This information is then used to identify, in real-time, drug cravings and deliver personalized, multimedia drug prevention interventions precisely at the moment of greatest physiological need.
Boyer and his teams examined the iHeal system architecture, as well as preliminary feedback from initial users, to identify key attributes and assess the device's viability. Their analyses suggest a number of technical issues related to data security, as well as the need for a more robust and less stigmatizing version before the device could be worn in public.
