Frequency of and risk factors for intensive care unit-acquired sacrum pressure injuries in critically ill patients: A multicenter cross-sectional study in China

摘要

Rationale, aims, and objectives Hospital-acquired pressure injuries (HAPI) prolong hospital stays and are an important health problem worldwide. The aim of this study was to assess the frequency of and risk factors for intensive care unit (ICU)-acquired pressure injuries (IAPI) on the sacrum in critically ill patients in China. Methods We performed a multicenter, cross-sectional survey of IAPI on the sacrum in 23 adult ICUs in 19 hospitals in China. Data for 421 critically ill patients were collected on December 13, 2019, and January 13, 2020, including patient characteristics, physiological, and clinical information. Logistic regression was used to analyze the risk factors for IAPI on the sacrum in the ICU. Results Forty-one patients presented sacrum pressure injuries in the ICU, with a frequency of 9.74%. Risk factors that significantly increased the risk of IAPI on the sacrum were lower body mass index (BMI, odds ratio [OR]?=?1.115, confidence interval [CI]: 1.011-1.229, P =?.029), chronic obstructive pulmonary disease (COPD, OR?=?3.183, CI: 1.261-8.037, P =?.014), multiple organ dysfunction syndrome (MODS, OR?=?2.670, CI: 1.031-6.903, P =?.043), and a lower Braden risk score (OR?=?1.409, CI: 1.197-1.659, P ?.001). Conclusion Lower BMI, COPD, MODS, and lower Braden risk score are independent risk factors for sacrum IAPI in China.
