The primary aim of this study was to compare patient reported versus clinician-observed nonulcerative foot conditions in patients attending a diabetic foot clinic and deemed at risk for diabetic foot ulcers.
Retrospective review of medical records.
The medical records of 126 patients with diabetes mellitus and deemed at risk for developing diabetic foot ulcers were reviewed. All patients received care from a diabetic foot outpatient clinic in a university-based hospital in Tokyo, Japan, between November 2008 and October 2009.
We compared patients' self-identified foot complaints with clinically observable conditions affecting the feet of these individuals with diabetes mellitus. Patients' medical records were retrieved, and patient complaints and identified preulcerative signs of the foot were documented. All clinical observations were made by nurse specialists with knowledge of diabetic foot conditions. Nonulcerative diabetic foot conditions we observed included calluses, corns, abnormal nails, fissures, tinea pedis, and tinea unguium. Patient sensitivity to correctly identify these signs was calculated using the following formula: patient-reported foot signs divided by clinically identified preulcerative signs.
Patient sensitivity for identifying nonulcerative signs varied based on the foot condition was 51.4% for calluses, 47.8% for pincer nails, 44.4% for corns, 33.3% for fissures, 19.4% for nail abnormalities, 3.9% for scales/maceration between the toes, 2.6% for interdigital tinea pedis, and 18.2% for tinea unguium.
These findings suggest that persons with diabetes vary in their awareness of conditions affecting their feet and enhancing their risk for the development of diabetic foot ulcers. We recommend additional education on foot-related self-care including how often to observe their feet and how to recognize symptoms that may elevate their risk for diabetic foot ulcers.
