PHOENIX: Craving Management Smartphone Application

Addictive disorders are a public health priority. The management of addictive disorders aims to reduce addictive behaviour or abstinence, implying that the patient can overcome the urge to engage in this behaviour, a symptom called craving. Craving, as a major motivational substrate for addictive behaviour, is a preferred therapeutic target for the management of addictive disorders. However, to date, there are no fully effective drugs or psychological interventions. Smartphone applications seem to have an interest in this context, with many advantages: accessibility, anonymity, ease of access and low cost. Sainte Anne's Hospital Moreau de Tour facility (Paris, France) was one of the pioneering centres in the management of addictive disorders. The nursing team has developed expertise in this field. Patients report difficulties to nurses about managing their craving on their own, and ask for more frequent interviews or even daily support. During practice analysis meetings, caregivers sought innovative solutions to optimize this care. Our team has designed the PHOENIX application, which allows us to support patients in real time who wish to reduce or stop their addictive behaviours. Used between two consultations, it targets craving, without being specific to a product or addictive behaviour. When the patient has a craving, PHOENIX identifies the situation and proposes the most appropriate strategy to avoid using. Strategies are personalized and self-adaptive. The application allows caregivers to monitor patients' progress and progress. Hypothesis of this study: The PHOENIX application used as a complement to nursing care will allow a better management of craving and a decrease in relapses compared to usual care (usual care: multidisciplinary care including nursing care).
