What is a significant risk factor for developing a decubitus ulcer?

Moisture is a significant risk factor for developing a decubitus ulcer, commonly known as a pressure ulcer or bedsore. When the skin is exposed to excess moisture, such as from sweat or incontinence, it can lead to skin maceration, which weakens the skin's integrity. This compromised state makes the skin more susceptible to injury, particularly when combined with other factors like pressure and friction from surfaces.

In contrast, high mobility, increased sensory perception, and regular exercise are factors that generally contribute to reducing the risk of pressure ulcers. High mobility allows for repositioning and redistribution of weight, which relieves pressure on specific areas. Increased sensory perception enables individuals to recognize discomfort and take action to change positions, thereby reducing the risk of skin breakdown. Regular exercise improves overall circulation and muscle tone, further supporting skin health and resilience against pressure-related injuries.
