Abstract
OBJECTIVE: To evaluate the predictive value of the Braden scale and laboratory indicators for oral mucosal pressure injury (OMPI) in patients admitted to the Emergency Intensive Care Unit (ICU). METHODS: A retrospective analysis was conducted on 238 intubated patients admitted to the First Affiliated Hospital of Anhui Medical University. Patients were divided into a training set (n = 166) and a validation set (n = 72). The training set was further classified into OMPI (n = 67) and non-OMPI (n = 99) groups. Clinical data were compared between the two groups, and a logistic regression model was constructed to develop a predictive nomogram. Model performance was assessed using discrimination and calibration metrics, and internal validation was performed with the validation cohort. RESULTS: The training and validation sets were comparable. Significant predictors of OMPI included Braden scale score (P < 0.001), ICU length of stay (P < 0.001), intubation duration (P = 0.039), and hemoglobin (P < 0.001). Logistic regression identified Braden scale, intubation duration, hemoglobin, and hematocrit as independent risk factors. CONCLUSION: The combination of Braden scale score, hemoglobin, and hematocrit demonstrated good predictive value for OMPI in EICU patients.
