The purpose of this analytic observational study was to examine the incidence and predicting factors for pressure injury of critically ill patients. 288 critically ill patients were recruited for this study by a consecutive sampling technique. The three instruments were used to collect data consisted of 1) the pressure injury risk assessment tool and content validity index was 0.94 2) the skin risk assessment tool 3) The Braden risk assessment scale. Inter-rater reliability of this instrument showed 1.0. Data were analyzed using descriptive statistics, chi-square test and stepwise multiple logistic regression. Results of the study revealed that vascular disease (OR= 5.29, 95%CI=1.37-20.29, p=.01), albumin level (OR= 5.19, 95%CI=1.17-23.05, p=.03), mechanical ventilator (OR= 3.37, 95%CI=1.39-8.16, p=.007) and edema (OR= 2.74, 95%CI=1.21-6.20, p=.01) were statistically significant in predicting pressure injury.
