Study summary

The purpose of this study is to investigate the relationship of hemoglobin A1c in diabetic wound healing. Additionally, a comparison of two wound dressings, AmeriGel® (Amerx Health Care Corp., Clearwater, FL) and Bacitracin, with and without vitamin C supplementation, will be done to evaluate impact on time to wound closure.

Read the detailed description

This is a prospective randomized controlled study evaluating the relationship of hemoglobin A1c in diabetic wound healing. Length of time for wound closure will be compared using four treatment options.

What researchers measure

Primary outcomes

  1. Hgb A1c Level

    Hgb A1c measures the average blood glucose over three months (% of hemoglobin). All subjects will be asked to get their hemoglobin A1c level at the beginning of the study and every three months for as long as they participate in the study.

    Time frame: Patients are assessed every 3 months from enrollment through end of study participation, which may be 6 months

Secondary outcomes

  1. Length of Time for Wound Closure

    Length of time for wound closure will be measured in days

    Time frame: Patients are assessed every other week (bi-weekly) until 100% wound healing is achieved, which may take up to 6 months

  2. Wound Area Measurements

    Wound area measurements in length, width, and depth throughout the course of the study(measured in cm).

    Time frame: Patients are assessed every other week (bi-weekly) until 100% wound healing is achieved, which may take up to 6 months
