Predictors of pressure injury development in critically ill adults: A retrospective cohort study

The purpose of this research was to identify predictors of pressure injury, using data from the electronic health records of critically ill adults. A retrospective cohort study was conducted using logistic regression models to examine risk factors adjusted for age, gender, race/ethnicity and length of stay. The study cohort included 1587 adults in intensive care units within an urban academic medical centre. The presence or absence of a hospital-acquired pressure injury was determined during monthly skin integrity prevalence surveys. All pressure injuries were independently confirmed by two Certified Wound Care Nurses. Eighty-one (5.1%) of the 1587 cohort patients developed pressure injuries. After adjusting for confounders, the clinical variables associated with pressure injury development included mean arterial pressure
