Pressure ulcers are a significant and increasing source of human suffering. The precise number of people who have pressure ulcers is unknown. However, conservative estimates indicate that well over a million persons in hospitals and nursing homes suffer from pressure ulcers. One large study found that one in four Americans who died in 1987 had a dermal ulcer. The prevalence of pressure ulcers is almost certain to grow due to increasing numbers of fragile elderly and survivors of serious trauma.
压疮是人类痛苦的一个重要且不断增加的来源。患有压疮的具体人数尚不清楚。然而，保守估计表明，医院和疗养院中有超过一百万人患有压疮。一项大型研究发现，1987年死亡的美国人中有四分之一患有皮肤溃疡。由于脆弱老年人和严重创伤幸存者的数量不断增加，压疮的患病率几乎肯定会上升。
