Abstract: Objective: To construct the Pressure Injury (PI) nursing decision support system and explore its effectiveness in PI management. Methods: Establish a research and development team, construct a PI assessment content and nursing measures knowledge base based on the latest guideline evidence and practice recommendations, and to design Human-computer interaction rules. Using computer intelligence achieve comprehensive evaluation and recording of PI. Compare the accuracy of PI staging and tissue type identification, the effectiveness of PI treatment, and the implementation rate of PI nursing record before and after the application of the decision support system. Results: After applying the decision support system, the correct rate of PI staging judgment increased from 84.5% to 96.0%, and the correct rate of tissue type judgment increased from 79.5% to 93.5%, the effective rate of PI treatment increased from 68.2% to 82.4%, the implementation rate of PI nursing records measured at 4 time points has increased from 75.4%, 81.1%, 88.3%, and 77.7% to 92.7%, 96.0%, 94.8%, and 94.3%, respectively, the differences were statistically significant (P<0.05). Conclusion: The use of the PI nursing decision support system improved the effectiveness of PI treatment and the standardization of nursing records, promoting an increase in the quality of PI nursing care.
