Conditions

Foot Ulcer, Foot Ulcer, Diabetic

Brief summary

All study procedures will occur during one appointment. The research team will measure the size of the foot ulcer (if one is present) and multiple photos will be taken with a smart phone camera and thermal camera. Demographic information will be obtained from the medical record.

Detailed description

The research procedures consist of a) a research assistant measuring the size of the foot ulcer (for ulcer patients), b) patients having pictures of their feet taken with a smart phone under 4 conditions- 1) photos taken by researchers, 2) photos taken by the patient by hand, 3) photos taken by the patient with a selfie stick, and 4) photos taken by a 3rd party (e.g., friend/family member of patient). If the patient is not able to take photographs under any of the conditions, that condition will be excluded. In addition to photos being taken with a smart phone, additional photos will be taken with a thermal camera by the research team to determine if there is a difference in ulcer size depending on type of camera used. It is anticipated that procedures will last between 15 and 45 minutes. There is no long-term follow-up. If a patient returns to the clinic they will be asked if they wish to complete all study procedures again. Once the patient has left the clinic, the research team will check the medical record for: age, sex, race, ethnicity, BMI, co-morbidities, and zip code (to determine if patient lives in an urban or rural location).

Design outcomes

Primary

MeasureTime frameDescription
Foot Ulcer Size45 minutesSize of foot ulcers will be determined by measurement and estimated by software

Secondary

MeasureTime frameDescription
Quality of Photos: 1 - 5 scale45 minutesQuality of foot ulcer photos will be quantitatively assessed using a 1 - 5 scale (with 1 being poor focus and lighting and 5 being excellent focus and lighting). These scores will be determined subjectively by multiple researchers and averaged to a single score.
