Although the DEPA Scoring System is a validated system, it involved a small number of patients and a relatively short follow-up period.1
Key Insights On The University Of Texas System
The University of Texas Classification of Diabetic Foot Wounds is becoming an increasingly popular system and has been validated in locations other than its original source.6
This straightforward system grades wounds first with numbers 0 to 3 referring to depth: 0 (pre- or post-ulcer with epithelialization), 1 (superficial and not involving tendon, bone or capsule), 2 (ulcer penetrates through to tendon or capsule) and 3 (penetrating to bone or joint).
A second classification tier, A to D, refers to other burdens on the wound. A indicates non-infected/non-ischemic, B indicates infection, C indicates ischemia and D indicates infection plus ischemia.
Clinicians may also utilize a complementary system called the Foot Risk Classification System, which was also developed at the University of Texas.7
This system allows the clinician to place the wound in an algorithm, based on its classification, that will maximize healing potential. This system allows the clinician to treat the wound based on a proven protocol that was successful for treatment of ulcers.
When explaining the University of Texas (UT) wound classification system to a visitor, one UT trainee said the system was akin to using a roadmap when you are trying to get to a destination. Without the roadmap, you do not know which road to take. You have stops and starts, take wrong turns and if you do get to your destination, in this case “healing,” it is by pure luck rather than by intention.
Diabetic wound healing is a complicated process that requires a definite plan based on scientific fact. A validated classification system can be the roadmap to get you there.
