Effectiveness of Multilayered Polyurethane Foam Dressings to Prevent Hospital-Acquired Sacral Pressure Injuries in Patients With Hip Fracture

PURPOSE: The purpose of this study was to determine the effectiveness of a multilayered polyurethane foam dressing applied within 24 hours of hospital admission compared with standard preventive pressure injury (PI) care in reducing sacral PI occurrence in older patients with hip fractures. DESIGN: Open-label, parallel-group, 2-arm, superiority trial. SUBJECTS AND SETTING: The sample comprised older patients aged 69 to 97 years admitted to a 1500-bed university hospital in Bologna, Italy, for hip fracture surgery. METHODS: Patients were randomly allocated to an intervention or control group. Both groups received standard evidence-based PI preventive care in accordance with National Pressure Ulcer Advisory Panel guidelines. In addition, patients in the intervention group received a single 12.9 × 12.9-cm multilayered polyurethane foam dressing shaped for the sacrum area applied within 24 hours of hospital admission. Bivariate analysis on primary and secondary outcomes and baseline characteristics was performed to compare group differences, and a survival analysis was used to determine the difference in PI incidence rates per group. RESULTS: Sixty-eight patients completed the trial; 34 patients were allocated to the intervention group and 34 patients to the control group. A trend toward significance was observed for sacral PI occurrence in the intervention group (intervention: 20.6%; control: 2.9%; P = .054). The foam dressing allowed significantly longer time (days) to PI occurrence (intervention: 5.9 ± 1.60; control: 2.7 ± 0.96; P = .003). CONCLUSIONS: These findings suggest that multilayered polyurethane foam dressings are not superior to the standard preventive PI care alone and should be used with caution, especially when multiple dressing changes may occur. Further exploration of the role of multilayered polyurethane foam dressings in preventing PI development is warranted.
