Evaluation of an advanced pressure ulcer management protocol followed by trained wound, ostomy, and continence nurses: a non-randomized controlled trial

Abstract

Aims and objectives: We investigated the effectiveness and safety of an advanced pressure ulcer (PU) management protocol comprising 1) ultrasonography to assess the deep tissue, 2) use of a non-contact thermometer to detect critical colonization, 3) conservative sharp debridement, 4) dressing selection, 5) negative pressure wound therapy, and 6) vibration therapy in comparison with those of a conventional approach. Each protocol was followed by trained wound, ostomy, and continence nurses (WOCNs). Background: At present, there is no systematic PU management protocol for nurses that includes appropriate assessment and intervention techniques for deep tissue injury and critical colonization. In Japan, there is no such protocol that the nurses can follow without a physician's orders. Design and methods: This was a prospective non-randomized controlled trial. Over a 3-week period, we evaluated the effectiveness of an advanced protocol by comparing the PU severity and healing on the basis of the DESIGN-R scale and presence of patients' discomfort. We recruited ten WOCNs to follow the advanced protocol and 19 others as controls. Statistical analysis included a linear mixed-effects model and a logistic regression model. Results: In week 0-1, the advanced protocol was significantly associated with prevention of PU deterioration. Using the linear mixed-effects model, we observed a greater decrease in the DESIGN-R score (healing) in the advanced protocol group. There were no reports of excessive bleeding, pain or infection with the advanced protocol. Conclusion: Using the advanced protocol, WOCNs detected PU severity, assessed PUs, and treated PUs safely. This protocol prevented PU deterioration and/or facilitated wound healing. Relevance to clinical practice: With proper training, WOCNs can assess and treat PUs safer and quicker than when a physician's assessment is required, leading to an improvement in wound healing and prevention of PU deterioration.
