Construction and Validation of a Risk Prediction Model for Peristomal Moisture-Associated Skin Damage in Older Patients With Enterostomies

The validated prediction model demonstrated high discrimination (AUC >0.90) and good calibration, providing an effective tool for the early identification of older patients undergoing enterostomy at high risk of PMASD. This model may guide individualized preventive strategies and optimize the continuity of care. Further multicenter prospective studies are needed to confirm the generalizability and clinical utility of our findings.
