Alarm algorithm and related intervention measures. In the algorithm, a “warning signal” will be prompted if temperature differences are > 1.5 °C between left and right corresponding sensor sites. The following levels have been implemented: level 0 = no “warning signal”; alarm level 1 = first “warning signal”; alarm level 2 = second “warning signal” after at least 4 h; alarm level 3 = third “warning signal” after at least 20 h; and alarm level 4 = fourth “warning signal” after at least 32 h. Alarm level 4 encompasses that the study physician interprets the alarm. Other eventful alarm levels (“noticeable,” “confirmation,” or “intervention”) will be automatically reset, if the previous “warning signal” disappears. The related intervention measures include (1) reminding the patient of regular foot care and temperature measurements (every alarm level), (2) performing foot photo documentation (alarm level 3 and 4), (3) interpreting warning signals (alarm level 4), (4) prescribing an intervention period of five days foot relaxation and reduction in daily activities, and (5) recording patients’ interactive feedback during this period
