Multicenter randomized controlled trial comparing the effectiveness and safety of hydrocellular and hydrocolloid dressings for treatment of category II pressure ulcers in patients at primary and long-term care institutions.

Background: Pressure ulcers are a major burden to patients because they affect health, well-being, and health-related quality of life. Thus, prevention and early treatment of pressure ulcers is a major challenge for health care professionals.

Objective: To compare the efficacy of hydrocellular and hydrocolloid dressings after 8 weeks of treatment of category II pressure ulcers.

A multi-center, randomized, clinical trial comparing adhesive polyurethane foam dressing and adhesive hydrocolloid dressing in patients with grade II pressure ulcers in primary care and nursing homes.

Background: Pressure ulcers (PrUs) are ischemic wounds in the skin and underlying tissues caused by long-standing pressure force over an external bone or cartilaginous surface. PrUs are an important challenge for the overall health system because can prolong patient hospitalization and reduce quality of life. Moreover, 95% of PrUs are avoidable, suggesting they are caused by poor quality care assistance.
