“…This variable was selected according to recommendations of the National Group for the Study and Assessment of Pressure Ulcers and Chronic Wounds (http://www.gneaupp.org) based on the National Pressure Ulcer Advisory Panel (NPUAP) (http://www.npuap.org). 22 The Mouseyes software program (version 2.1) was used to calculate wound areas derived from digital camera image files 23. The percentage of surface area healed was estimated as “initial ulcer surface − final ulcer surface/initial ulcer surface × 100”.…”

Effectiveness of autologous preparation rich in growth factors for the treatment of chronic cutaneous ulcers

et al. 2007

Autologous Preparation Rich in Growth Factors (PRGF), a small volume of plasma enriched in platelets, is a novel therapeutic strategy for the acceleration of the wound healing of a wide range of tissues because of the continuous release of multiple growth factors, including PDGF-AB, TGF-beta1, IGF-I, HGF, VEGF-A, and EGF. In this article, we have characterized the PRGF preparation and designed a randomized open-label controlled pilot trial to evaluate the effectiveness of PRGF in the treatment of chronic cutaneous ulcers. Results showed that at 8 weeks, the mean percentage of surface healed in the PRGF group was 72.94% +/- 22.25% whereas it was 21.48% +/- 33.56% in the control group (p < 0.05). These results, with the limitations of a pilot study, suggest that topical application of PRGF is more effective than standard therapy in helping a chronic ulcer to heal.

“…Some studies have evaluated the computerized planimetry for surface area measurement, and have also reported excellent ICC values ( > 0.90). 24,26,27,[33][34][35] In the literature, wound debridement was studied using objective digital image processing. Oduncu et al 36 quantified the amount of slough in a wound bed using a software package (Hue Saturation Intensity color representation model) compared with a grading system based on visual inspection by an experienced clinician.…”

The purpose of this study was to examine the intra-and interrater reliability of three methods to measure the percentage of fibrin within a wound, hence reflecting wound debridement. The three methods include visual assessment, a portable wound measurement system (PWMS) Visitrak s , and a computerized planimetry software Canvas s . The main objective was to compare the computerized planimetry with visual analysis. For each wound, a series of two repeated recordings of fibrin percentage based on the same Day 1 photograph at Day 8 and Day 15, respectively, was assessed by four evaluators using the two methods. Additional objectives consisted in the assessment of the inter-rater reliability of computerized planimetry and PWMS to assess fibrin percentage and total surface area. Twenty-four patients were included for a total of 31 wounds. Intraclass correlation coefficient revealed improved reproducibility and repeatability of computerized planimetry. The reproducibility of computerized planimetry was better than PWMS when measuring the percentage of fibrin and total wound area. Because average visual estimations were very close to the computerized planimetry, bedside evaluation of fibrin percentage and wound debridement was considered as reliable, and consequently a valid technique for daily practice. PWMS proved to be less convenient, owing to difficulties in identifying fibrin margins. The higher intra and interrater reliability of computerized planimetry probably reflected the fact that subjective clinical assessment and objective calculation of percentages were mandatory for correct wound evaluation. Therefore, digital image analysis was considered as an accurate method for double-blind and multicentric trials.Chronic wounds are a major problem in developed countries resulting in substantial morbidity and cost to healthcare systems.

“…These techniques require sophisticated, expensive and relatively cumbersome instrumentation at the patient's side. With wide availability of digital cameras, a more attractive option is to capture a digital image of the wound for subsequent computerised analysis (44). In effect, this converts a 3D image into 2 dimensions, and single plane photographs are inherently limited by this transformation.…”

A significant proportion of chronic wounds fail to heal in response to treatment of underlying pathologies combined with good wound care practice. Current prognostic tests to identify these wounds rely on the use of algorithms based on clinically measurable parameters such as wound dimensions and wound duration. Venous leg ulcers may be stratified into healing/non healing at 24 weeks of compression therapy and diabetic foot ulcer treatment outcome assessed using a 3-parameter algorithm. Accurate and reproducible measurement of wound area is required for these algorithms to have clinical utility. Whilst a number of attempts have been made to develop computerised wound-assessment techniques, wound tracing by clinicians combined with planimetry remains the standard methodology. Once treatment has been initiated, it is important to continuously monitor the wound to assess efficacy of treatment. This can be achieved by measuring wound area change over the first weeks of treatment to identify whether re-assessment of treatment strategy is required. A number of algorithms for assessing rate of wound area change have been evaluated to determine a surrogate endpoint for healing. Retrospective analysis of large patient groups indicates that approximately 75% correct prediction of healing outcome can be achieved.

Mouseyes revisited: upgrading a computer program that aids wound measurement

Abstract: A computer program (Mouseyes) for measuring wounds has been upgraded to incorporate the use of photographic images taken with a digital camera. This evaluation showed that the upgrade produced accurate and reproducible results.
