Nationwide cost estimates of 60 major illnesses place alcohol use disorders as the 2nd and drug use disorders as the 7th most costly health problems. Both are related to higher rates of HIV risk behaviors associated with the human immunodeficiency virus (HIV) and together they represent 3 of the top 10 modifiable behavioral causes of mortality in the US. Studies indicate that effective strategies for managing substance use disorders (SUD) must address their chronic and cyclical nature, of which HIV risk is a part. For many, substance use creates circumstances that increase HIV risk (e.g., needle use, trading sex) and for others, substance use is a coping mechanism for the negative impact of lifestyle choices (e.g. illegal activity, losing custody of their children, trading sex). Post-discharge monitoring, feedback and early re-intervention have become standard practice when managing numerous chronic conditions.10 Mobile technology has the potential to radically improve the odds of sustained recovery by providing tools for ongoing monitoring, assessment and access to recovery support interventions anytime and anywhere. This is particularly important for the 90% of those needing treatment that don't receive it. Therefore applying smartphone technology to provide recovery management anytime anywhere is potentially significant.
