Suspected deep tissue injury (sDTI) was identified in 2001 and added as a staging definition by the National Pressure Ulcer Advisory Panel in 2007. Clinical data on sDTI are sparse. This article reports the overall prevalence data and describes the demographics of subjects with sDTI from the International Pressure Ulcer Prevalence survey 2006-2009.
Participating healthcare facilities performed prevalence surveys in their facility during a pre-determined 24-hour period within a pre-selected 2- to 3-day window. All generated data was incorporated into the database, even if specific data fields were absent.
Approximately 79,000 to 92,000 patients were surveyed each year from 2006 to 2009. The overall and nosocomial pressure ulcer (PrU) prevalence decreased by approximately 1% in 2009 (P < .001), after remaining fairly constant in the years 2006-2008. The proportion of ulcers identified as sDTI has increased 3 fold, to 9% of all observed ulcers in 2009 and is more prevalent than either Stage III or IV ulcers. Over the same period, the proportion of Stage I and II ulcers have decreased, and the proportion of Stage III and IV ulcers has remained nearly constant. Patients with sDTIs are older than patients with Stage III, IV, and Unstageable ulcers. The anatomic location of sDTIs are more commonly found at the heel (41%), the sacrum (19%), or the buttocks (13%). Compared with other staged ulcers, sDTIs are significantly more prevalent at the heel (P < .001) and the ankle and foot (P < .001) and less prevalent at the sacrum and coccyx (P < .001) and at the buttocks and ischial tuberosities (P < 0.001).
The survey data indicate that a decrease in overall prevalence of PrUs, as well as hospital-acquired PrUs, may have occurred in 2009. Suspected deep tissue injuries have become more commonly identified, which may be secondary to education of staging definitions.
可疑深部组织损伤（sDTI）于 2001 年被识别，并于 2007 年被国家压疮咨询小组（NPUAP）添加为分期定义。目前关于 sDTI 的临床数据较为缺乏。本文报告了 2006-2009 年国际压疮流行率调查中 sDTI 的总体流行率数据，并描述了患有 sDTI 的患者的人口统计学特征。
参与研究的医疗机构在预先选定的 2-3 天时间窗内，在预先确定的 24 小时内，对其医疗机构内的患者进行流行率调查。所有生成的数据都被纳入数据库，即使某些数据字段缺失。
2006 年至 2009 年，每年约有 79000 至 92000 名患者接受了调查。2009 年，总体和医源性压疮（PrU）的流行率下降了约 1%（P<.001），而 2006-2008 年期间基本保持稳定。被确定为 sDTI 的溃疡比例增加了 3 倍，在 2009 年达到所有观察到的溃疡的 9%，且比 III 期或 IV 期溃疡更为常见。同期，I 期和 II 期溃疡的比例下降，而 III 期和 IV 期溃疡的比例基本保持不变。患有 sDTIs 的患者比患有 III 期、IV 期和无法分期溃疡的患者年龄更大。sDTIs 的解剖位置更常见于足跟（41%）、骶骨（19%）或臀部（13%）。与其他分期溃疡相比，sDTIs 在足跟（P<.001）和踝关节及足部（P<.001）更为常见，在骶骨和尾骨（P<.001）以及臀部和坐骨结节（P<.001）处则更为少见。
调查数据表明，2009 年，总体 PrU 流行率以及医源性 PrU 流行率可能有所下降。可疑深部组织损伤的识别率有所增加，这可能与分期定义的教育有关。
