The summary and book chapter below represent our contributions to this text. The topic remains an area I have great enthusiasm about and high hopes for, when executed well.

Irrational use of medications is a global challenge, with the World Health Organization (WHO) estimating that “more than half of all medicines are prescribed, dispensed, or sold inappropriately”. This situation is exacerbated by half of all patients not taking their medications as intended, with non-adherence rates in disorders like schizophrenia reaching over 70%. Medication non-adherence and polypharmacy (i.e., use of multiple medications) are massive barriers to optimal medication management and are the source of substantial health and financial costs. Mobile health (mHealth) offers myriad methods to address these challenges, ranging from simple text message reminder systems to ecological momentary interventions (EMIs) to leveraging interface versatility for eHealth literacy solutions. In this chapter, current scientific evidence will be used to explore the role of mHealth in enhancing pharmacy-related outcomes in varying healthcare settings and diverse populations. Current and future developments in mHealth will be explored through the lens of select disease states and patient populations.
