4 Although highly inaccurate, the ruler method yields fairly reproducible results from measurement to measurement. Studies have shown wound area calculations using the L × W ruler method can overestimate area by 44%, 5 especially for wounds with irregular edges. The deviation from the true area is dependent on multiple factors, including wound bed size and shape, which are easily distorted by body position.
#RULER MEASUREMENT MANUAL#
The manual ruler method is quick and noninvasive, but the area measurements are almost always inaccurate as the length × width (L × W) technique assumes a square or rectangular wound shape. 1– 3 This technique resulted in the least overestimation of wound area in a study by Langemo et al. The website and PUSH Tool instruct clinicians to measure the longest length of the wound head to toe and then the longest width of the wound, taking the width measurements perpendicular to the length measurement. Clinicians can use the PUSH Tool to document healing or wound deterioration over time. The PUSH Tool is designed to document data on a complete pressure ulcer assessment, which is then tabulated for a total score. 1 Although there are several variations on the ruler method, a common practice is outlined by the National Pressure Ulcer Advisory Panel (NPUAP) on its website and in the NPUAP Pressure Ulcer Scale for Healing (PUSH) Tool version 3.0.
