| Research Abstract |
The final study of this project is an evaluation of the effectiveness of a newly-developed dressing for preventing persistent erythema and pressure ulcer development and improving the skin water-holding capacity without increasing the skin pH in bedridden older patients. Shear forces and skin dryness play important roles in persistent erythema and pressure ulcer development. To eliminate these risks, we developed a dressing to reduce shear forces and improve the water-holding capacity. However, the effects of this dressing in clinical settings remain unknown. An experimental bilateral comparison study was conducted at a hospital in Japan in 2004 with 37 bedridden older patients at risk of pressure ulcer development. The dressing was randomly applied to the right or left greater trochanter for three weeks. No dressing was applied to the opposite side as a control. The skin was monitored weekly during the three-week application for persistent erythema and pressure ulcer development. Skin hydration and pH were also assessed during the intervention and for one week after dressing removal. The incidence of persistent erythema was significantly lower in the intervention area than the control area [P=0.007, RR 0.18 (95% C: 0.05-0.73) and NNT 4.11 (2.50-11.63)]. No pressure ulcers occurred in either intervention or control area. Skin hydration increased significantly during dressing application and remained high after removal (P<0.001) relative to the control area. Skin pH decreased significantly during the application (P<0.001) but returned to control levels after removal (P=0.38). This safe and effective dressing can be used for patients with highly prominent bones and dry skin to prevent pressure ulcers.
