In recent decades, the use of new information and communications technology (ICT) has had an unparalleled development in both medicine and public health. Evidence shows that its use is effective for not only optimizing the delivery of the results (for example, medical studies or clinical analyses) but also for reminding patients of their doctor´s appointments. In addition, it has shown to benefit adherence to treatments for diverse pathologies, such as diabetes. The incorporation of digital communication in health care is a relatively simple strategy which can have a great impact on the community´s health.

Interventions based on text messages (SMS) are viable and can reach important sectors of the population. SMS sent via cellular telephony have some advantages over other types of technology, as it allows information to be broadcasted simultaneously, has a large scope and, most importantly, reaches all cellphones. You don’t need a Smartphone to receive an SMS.

From the patients’ perspective, SMS are easy to use and are effective in reminding them about information regarding appointments, when to take their medicine, or when to have a check-up.
