          ABSTRACT

          The study objective was to examine precision in wound measurement using a recently Food and Drug Administration-approved Scout (WoundVision, LLC, Indianapolis, Indiana) device to measure wound length (L) and width (W). Wound perimeter and a ruler measurement of L and W were also made. Images of 40 actual patient wounds were measured using the Scout device. All 3 techniques (length, width, perimeter) demonstrated acceptable within and between reader precision; however, the best precision was in wound perimeter measurement.

          MEASURE: A proposed assessment framework for developing best practice recommendations for wound assessment.

          The effective management of nonhealing wounds is based on a complete patient history, a detailed initial assessment of the wound, and an analysis of probable causative factors. This information is used to individualize a management strategy to the underlying pathophysiology preventing healing and to implement appropriate wound interventions. Regular reassessment of progress toward healing and appropriate modification of the intervention are also necessary. Accurate and clinically relevant wound assessment is an important clinical tool, but this process remains a substantial challenge. Wound assessment terminology is nonuniform, many questions surrounding wound assessment remain unanswered, agreement has yet to be reached on the key wound parameters to measure in clinical practice, and the accuracy and reliability of available wound assessment techniques vary. This article, which resulted from a meeting of wound healing experts in June 2003, reviews clinically useful wound measurement approaches, provides an overview of the principles and practice of chronic wound assessment geared to a clinical audience, and introduces a simple mnemonic, MEASURE. MEASURE encapsulates key wound parameters that should be addressed in the assessment and management of chronic wounds: Measure (length, width, depth, and area), Exudate (quantity and quality), Appearance (wound bed, including tissue type and amount), Suffering (pain type and level), Undermining (presence or absence), Reevaluate (monitoring of all parameters regularly), and Edge (condition of edge and surrounding skin). This article also provides some preliminary recommendations targeted to developing best practice guidelines for wound assessment.

            Wound outcomes: the utility of surface measures.

            T L Gilman (2004)
            The value of using quantitative measures to follow the progress of wound healing is well recognized. However, several methods are in use, and the best way to do this is not always clear from the literature. This article describes the advantages of the linear healing parameter and the disadvantages of the area- and volume-based parameters. The shapes and sizes of wounds influence area- and volume-based parameters, hence these will give biased comparisons. Healing rates based on the linear parameter are independent of initial wound size or shape, and they allow unbiased comparisons within and across studies. A formula for predicting healing time from measurements early in the healing course is presented and discussed. Less precise linear healing measurements that are easy to obtain, and that are as valid as the more precise measurements, are also described.

              A Comparison of Wound Area Measurement Techniques: Visitrak Versus Photography

              Objective: To investigate whether a cheap, fast, easy, and widely available photographic method is an accurate alternative to Visitrak when measuring wound area in cases where a non–wound-contact method is desirable. Methods: The areas of 40 surgically created wounds on porcine models were measured using 2 techniques—Visitrak and photography combined with ImageJ. The wounds were photographed with a ruler included in the photographic frame to allow ImageJ calibration. The images were uploaded to a computer and opened with ImageJ. The wound outline was defined from the photographic image using a digital pad, and the ImageJ software calculated the wound area. The Visitrak method involved a 2-layered transparent Visitrak film placed on the wound and the outline traced onto the film. The top layer containing the tracing was retraced onto the Visitrak digital pad using the Visitrak pen and the software calculated the wound area. Results: The average wound area using the photographic method was 52.264 cm2 and using Visitrak was 51.703 cm2. The mean difference in wound area was 0.560 cm2. Using a 2-tailed paired T test, the T statistic was 1.285 and the value .206, indicating no statistical difference between the two methods. The interclass correlation coefficient was 0.971. Conclusions: The photographic method is an accurate alternative to Visitrak for measuring wound area, with no statistical difference in wound area measurement demonstrated during this study. The photographic method is a more appropriate technique for clean and uncontaminated wounds, as contact with the wound bed is avoided.
