In the 1993 survey, the prevalence of pressure ulcers was 11.1% in 177 hospitals. This is higher than the 9.2 prevalence rate Meehan found in 1989. The sacrum, with 38% (n = 2,168) of all reported ulcers, remains the most common site for pressure ulcer occurrence. Non-reactive hyperemia sites, Stage I, were responsible for most reported ulcers, at 46.95% (n = 2,839), while Stage II ulcers comprised 32.66% (n = 1,975). Patients between the ages of 70 and 89 years of age had 54% of the ulcers found. The average number of ulcers per patient was 1.73. Dark-skinned, African-American patients again were found to have the majority of Stage IV ulcers. There were 1,024 ulcers reported in this stage group, and of these, they had 16% (n = 164). Of patients with ulcers, 22% were on some form of air or foam overlay support system; however, standard mattresses and mattress replacements were used for 31% of all patients with pressure ulcers.
在1993年的调查中，177家医院的压疮患病率为11.1%。这高于米汉在1989年发现的9.2%的患病率。骶骨是压疮最常见的发生部位，所有报告的溃疡中有38%（n = 2168）发生在此处。无反应性充血部位（I期）是报告的大多数溃疡的所在部位，占46.95%（n = 2839），而II期溃疡占32.66%（n = 1975）。70至89岁的患者中有54%的溃疡被发现。每位患者的溃疡平均数量为1.73个。深色皮肤的非裔美国患者再次被发现患有大多数IV期溃疡。在该阶段组报告的1024个溃疡中，他们占16%（n = 164）。在患有溃疡的患者中，22%使用了某种形式的空气或泡沫覆盖支撑系统；然而，31%的所有压疮患者使用的是标准床垫和床垫替代品。
