Wound infection assessment tools: Appendix N

Wound infection assessment tools, NERDS© and STONEES© are methods used to systematically assess for superficial critical colonization (localized infection) and deeper and surrounding infection (systemic infection), respectively, in people with pressure injuries. The methods described in this resource are suggestions that were identified through the systematic review and by feedback from the expert panel or external reviewers. Both kinds of infections must be treated in order to avoid delays in wound healing.
