Wound debridement: Comparative reliability of three methods for measuring fibrin percentage in chronic wounds.

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(R), and a computerized planimetry software Canvas(R). The main objective was to compare the computerized planimetry with visual analysis.
