“…Traditional methods estimate the dimensions of wounds including surface area and volume. 6,7 Physiological approaches utilize molecular and biochemical indicators that provide less subjective information. 3,8 Because successful wound healing is a dynamic process that integrates physiological and biochemical factors and mechanisms, reliance on a single aspect of the process may be inadequate.…”

Abbreviations: (AC) alternating current, (BIA) bioelectrical impedance analysis, (ECF) extracellular fluid, (MRSA) AbstractObjective assessment of wound healing is fundamental to evaluate therapeutic and nutritional interventions and to identify complications. Despite availability of many techniques to monitor wounds, there is a need for a safe, practical, accurate, and effective method. A new method is localized bioelectrical impedance analysis (BIA) that noninvasively provides information describing cellular changes that occur during healing and signal complications to wound healing. This article describes the theory and application of localized BIA and provides examples of its use among patients with lower leg wounds. This promising method may afford clinicians a novel technique for routine monitoring of interventions and surveillance of wounds.

“…Ruler measurements have been shown to be reliable (defined as high intraand inter-measurer consistency) [5,6,7] and capable of predicting healing [8], even though they tend to overestimate ulcer size [5,6,9,10] and are influenced by wound shape [5,11]. Transparency tracings have also been shown to have high reliability [7], but can be tedious and susceptible to subjectivity [6].…”

Measurement of skin ulcer area is essential for accurate assessment of the efficacy of different therapeutic strategies. Currently, measurement options involve subjective evaluation of ulcer borders. We quantified ulcer surface area in twelve sickle cell anemia patients by using an infrared (IR) camera and compared measurements to those obtained with standard, manual techniques that utilize visible light. IR photography is sensitive to ulcer border irregularity and capable of discerning thin epithelialization layers that are invisible, due to transparency, to the human eye or ordinary photography. The technique is non-invasive, objective, and capable of visualizing ulcers through thin dressings.

“…Although this method is relatively easy and has good reliability, variability in its results arises when determining whether or not to count partial squares within a trace [8,9]. Digital planimetry may provide a more precise and objective approach than the RT method with grid-square counting for calculating the surface area of wounds and is more amenable to calculating the areas of irregularly shaped wounds (Table 2) [10]. For DP, a digital rendering of the trace along the margins of a lesion is created, and software is used to calculate the wound surface area.…”

Background: In August 2010, the U.S. Food and Drug Administration issued draft guidelines for developing antibiotics for treating acute bacterial skin and skin structure infections (ABSSSI), with the outcome measure of such treatment relying primarily on the cessation of spread or on the decrease in size of skin lesions at 48-72 h after the initiation of such treatment. In 2012, the Foundation for the National Institutes of Health proposed an interim outcome measure defined as a reduction in lesion size by ‡ 20% at a 48-72 h examination. These recent changes make it necessary to identify reliable methods for measuring the lesions in acute infections of the skin. Methods: In the first study of the Efficacy and Safety of 6-day Oral Tedizolid in Acute Bacterial Skin and Skin Structure Infections vs. 10-day Oral Linezolid Therapy (ESTABLISH-1), the sizes of ABSSSI lesions were evaluated with the two methodologies of: (1) Digital planimetry (DP) of photographed lesions, and (2) a ruler technique (RT) with measurement of the longest head-to-toe length and greatest perpendicular width of lesions, to compare the respective response rates of lesions to the two antimicrobial regimens in the study. Results: The RT method and DP showed similar percentages of subjects in which treatment stopped the spread of ABSSSI lesions (93.2% vs. 94.2%, respectively) but showed less agreement for a reduction in lesion size, of ‡ 20% (87.7% vs. 62.0%, respectively) across all categories of lesions (cellulitis/erysipelas, major cutaneous abscess, and acute wound infection) at 48-72 h after the initiation of treatment. Conclusion:The results of the ESTABLISH-1 study show that both the RT method and DP are consistent and reliable techniques for measuring the sizes of ABSSSI lesions. Ultimately, changes in lesion size, rather than the absolute value of lesion size, will be used to assess the outcomes of treatment for ABSSSI in clinical research.
