Abstract:

Objective This research is to develop a clinical decision support system for pressure injury（PI）and explore its application effect in clinical PI management. Methods A Research & Development team was set up to build a PI knowledge base and a database of nursing documents,and to design human-computer interaction rules,in order to realize functions such as dynamic assessment and early warning,intelligent interpretation and recommendation,real-time monitoring and analysis,etc. Indicators before and after the application,including the ratios of timely risk assessment upon hospital admission,the rates of qualified implementation of risk assessment-based preventive measures,the rates of defect in nursing records,the occurrences of hospital acquired PI,and the occurrence of hospital acquired PI in high-risk patients. Results After applying the clinical decision support system for PI,the ratio of timely risk assessment upon hospital admission increased from 84.78% to 95.94%;the rate of qualified implementation of risk assessment-based preventive measures increased from 90.15% to 99.13%;the rate of defect in nursing records decreased from 16.42% to 8.70%;and the differences were statistically significant（P<0.001）. The occurrence of hospital acquired PI and the occurrence of hospital acquired PI in high-risk patients were both lower. Conclusion The clinical decision support system for PI provides nurses with accurate and objective decision-making basis,thus effectively improves the quality of PI care and upgrades management efficiency.
