Wound Measurement and Documentation

A wound measurement is more than a number in a chart. It provides a reproducible way to judge whether tissue loss is shrinking, remaining static, or extending under the current plan of care. The dimensions must be interpreted with the rest of the assessment. A wound can have the same length and width while becoming deeper, developing undermining, producing more drainage, or causing new pain. Conversely, a small change in surface area may reflect a different client position or a different measurement technique rather than true healing. Reliable trends depend on reliable technique. Measurement does not establish the wound’s cause or diagnose infection by itself. The assessment must also consider the wound location and known or suspected aetiology, the wound bed, drainage, edges, periwound skin, pain, and the client’s systemic condition. In Canada, an RPN completes wound measurement and documentation only within provincial regulation, employer policy, competence, and the assigned plan of care. Findings that exceed the RPN’s role or suggest deterioration are communicated promptly through the local RN, prescriber, or wound-care consultation pathway.
