Implementation of Foot Thermometry and SMS and Voice Messaging to Prevent Diabetic Foot Ulcer

"This group will receive reminders to use the TempStat (two messages) and promote foot care (six messages). The content of these eight messages have been developed and validated their delivery through both, SMS and voice messaging.~During the first two weeks of the intervention, only reminders to use the TempStat will be sent, daily, Monday to Friday, both via SMS and voice messaging.~Hereafter, for the remaining 76 weeks, patients will only receive two messages per week, one SMS and one voice message, alternating content (reminders to use TempStat and promotion of foot care)."

Subjects will be provided with a TempStat (foot thermometer), a device that captures a thermal image of feet. (See Detailed description)
