The Impact of Text Messaging in Adherence Programs
Average adherence rates for chronic treatment average approximately 50%, leading the World Health Organisation (WHO) to state that increasing the effectiveness of adherence interventions may have a far greater impact on the health of the population than any improvement in specific medical treatments and new drugs per se. In this environment, programs designed to increase adherence to medication and to treatment in general have multiplied over the past several years. These programs generally include communication with patients to inform and influence behavior. This communication can take place via a number of channels, ranging from face-to-face contact to physical mail to smart phone apps. Each channel has its own advantages and disadvantages and each entails costs of its own. Short Message Service (SMS) or text messaging has proven in numerous studies to represent an advantageous cost / benefit profile, particularly when the messages are customized to individual patients. This is the case across a wide variety of patient types, ages, pathologies and geographies. The present article provides an overview of the challenges of treatment adherence and how these can be successfully addressed using text messaging interventions across a variety of chronic illness and within different geographical and cultural settings.
