Overview
Screening
- The main focus of diabetic foot screening should be on peripheral neuropathy detection, since foot ulcer development is rare in the absence of neuropathy. However searching for other factors such as skin integrity, any wound or ulceration, anatomical deformities, nail changes and distal pulses should not be missed during foot examination.[1][2][3]
- A regular foot examination should be done in diabetic patients, in order to detecting peripheral neuropathy, peripheral arterial disease and anatomical foot deformities.[4]
- It is recommended to perform a careful foot examination at least annually in diabetic patients who are over the age of 15. Nevertheless physicians should educate patients to perform self foot examination more often.
- In diabetic patients who have higher risk of diabetic foot ulceration more frequent (every 1-6 months) examinations and follow up should be considered.
- An evidence‐based guideline published by the International Working Group on the diabetic foot (IWGDF), has been demonstrated a risk stratification system for detecting diabetic patients with high risk of foot ulceration. The aforementioned guideline has been developed a scoring system which clarify the proper intervals for screening diabetic patients. The following table is a summary of this system:[5][6]
| Characteristics | Score | Risk of ulcer development | Recommended screening frequency |
|---|---|---|---|
| Intact protective sensation of foot Absent of peripheral artery disease |
0 | Very low | Annually |
| Impaired protective sensation of foot OR Peripheral artery disease |
1 | Low | Every 6‐12 months |
| Impaired protective sensation of foot AND peripheral artery disease OR Impaired protective sensation of foot AND foot deformity OR Peripheral artery disease AND foot deformity |
2 | Moderate | Every 3‐6 months |
| Impaired protective sensation of foot OR peripheral artery disease AND at least one of the following: Previous history of a foot ulcer Previous history of amputation of a lower extremity End‐stage renal disease |
3 | High | Every 1‐3 months |
- The following are some useful screening tools for diabetic foot screening:[7][8][9][10]
- Semmes-Weinstein monofilament
- Tuning fork
- Biothesiometer
