The aim of this study was to identify factors associated with pressure injury (PI) occurrence in critically ill patients. This was a retrospective cohort study conducted at a mixed intensive care unit (ICU).
Univariate analysis and logistic regression were used to identify which variables are associated with PI.
Twenty-one (15%) of 142 patients developed PI. The median and the range of the variables in the groups without and with PI were as follows: Braden scale risk score, 13 (8 - 20) and 10 (8 - 14) points, respectively; Acute Physiology and Chronic Health Evaluation II (APACHE II) death risk, 39% (2 - 97%) and 75% (26 - 96%), respectively; and length of stay in the ICU, 4 (2 - 36) and 16 (5 - 29) days, respectively. The socio-demographic variables included in the logistic regression were age (P = 0.09), Braden scale risk score (P = 0.0003), APACHE II death risk (P < 0.0001), length of stay in the ICU (P < 0.0001) and reason for ICU admission (P = 0.09). Only APACHE II death risk and length of stay in the ICU presented significant differences; the odds ratios were 1.05 and 1.25, respectively, and the 95% confidence intervals were 1.01 - 1.09 and 1.12 - 1.39, respectively.
APACHE II death risk and length of stay in the ICU are probably associated with PI occurrence in the study population.
本研究旨在确定危重症患者发生压力性损伤（PI）的相关因素。这是一项在综合性重症监护病房（ICU）进行的回顾性队列研究。
采用单因素分析和逻辑回归来确定哪些变量与PI相关。
142例患者中有21例（15%）发生了PI。无PI组和有PI组变量的中位数及范围如下：Braden量表风险评分分别为13分（8 - 20分）和10分（8 - 14分）；急性生理与慢性健康状况评价II（APACHE II）死亡风险分别为39%（2 - 97%）和75%（26 - 96%）；ICU住院时间分别为4天（2 - 36天）和16天（5 - 29天）。纳入逻辑回归的社会人口统计学变量包括年龄（P = 0.09）、Braden量表风险评分（P = 0.0003）、APACHE II死亡风险（P < 0.0001）、ICU住院时间（P < 0.0001）和入住ICU的原因（P = 0.09）。只有APACHE II死亡风险和ICU住院时间存在显著差异；优势比分别为1.05和1.25，95%置信区间分别为1.01 - 1.09和1.12 - 1.39。
在本研究人群中，APACHE II死亡风险和ICU住院时间可能与PI的发生有关。
