Many valid and reliable tools and techniques are available for wound measurement. However, few prospective clinical studies assessing these instruments have been conducted. A prospective, methodological study was conducted between September 2006 and November 2007 to evaluate use of the Pressure Ulcer Scale for Healing (PUSH) version 3 in patients with one or more pressure ulcer. A convenience sample of 72 persons (mean age 66.9 +/- 12.8 years) with 86 pressure ulcers (49% Stage II, 47% Stage III, and 4% Stage IV) was recruited and assessed weekly until healing, transfer, patient death, or end of study for a maximum of 8 weeks. Most ulcers (77%) were in the sacral area and 56% had been present for 1 month or longer. Repeated measures analysis revealed that PUSH total scores decreased significantly (P < 0.001) over the 8-week study, with significant differences in PUSH total scores between healed and unhealed ulcers each week, starting on week 1. The total PUSH score as well as the length x width item in the tool accurately differentiated between healed and nonhealed ulcers. Although the PUSH tool is practical, easy-to-use, and generally sensitive to change, some modifications would improve its value--ie, a wound size/depth subscale. Additional studies to help clinicians more accurately evaluate the effectiveness of their interventions, including studies to determine whether wound measurements alone may suffice to monitor healing, are needed.
