Abstract: Objective To develop an intelligent decision system for stress injury care assessment and explore its effectiveness in pressure injury patients. Methods A research and development team was established to set up intelligent decision rules with reference to the prevention and treatment of pressure injuries: Quick Reference Guide 2019 as a guiding blueprint. Based on hospital clinical information system, and computer information technology, the overall framework of the system including interface layout, partitioning, module structure, content and functions was developed in a multi-angle and multi-directional way for intelligent decision-making, health education pushing dual pathways, quality control indicator monitoring, etc., and the implementation of indicators such as the timely rate of risk assessment within 8 hours of admission and the incidence of in-hospital PI. Results After the application of intelligent decision system for pressure injury care assessment, the timely rate of risk assessment within 8h of admission increased from 84.7% to 95.7% but the rate of missed Braden assessment decreased from 8.7% to 3.7% and the accuracy rate of Braden assessment, trauma assessment, and trauma management increased from 75.5% to 84.4%, from 77.2% to 87.3% and from 68.3% to 79.3% respectively. The transfer rate of pressure injury increased from 56.6% to 86.7%, and all the differences were statistically significant (P<0.05). The incidence of in-hospital PI decreased from 0.7 ‰ to 0.3‰. Conclusion Intelligent decision system for stress injury care assessment is automated, intelligent and information-based. It provides nurses with accurate and objective decision-making basis, which can make intelligent decisions on the staging of patients with stress injury and improve nursing quality and management effectiveness.
