Since ulcers develop as a result of cumulative injury over the course of several days, patients need a mechanism to identify early warning signs of ulceration to prompt them to take appropriate action.44 The high re-ulceration rates reported in previous studies indicate that early warning signs are missed. A home temperature monitoring system for wound prevention is a similar concept to home glucose monitoring to help patients adjust their insulin. In both cases patients need frequent information about a health parameter that has the potential to change in a very short period of time. In both cases patients are taught to use the objective data provided from their home monitoring device to alter their behavior whether it is used to change insulin dosage or activity level. One of the barriers to lowering the incidence of ulcers and amputation is an objective mechanism that patients can use at home, such as a home monitoring system.
