Predictive value of Braden scale combined with hemoglobin and hematocrit for oral mucosal pressure injury risk in ICU patients.

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.
