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.

摘要：

目的 研发压力性损伤（pressure injury,PI）临床决策支持系统,探讨其在临床PI管理中的应用效果。方法 成立研发小组,构建PI领域知识库和护理文书数据库,设计人机交互规则,以实现动态评估预警、智能判读推荐、实时监测分析等功能。比较该系统应用前后PI入院风险评估及时率、预防措施落实与风险评估合格率、护理记录缺陷率、医院获得性PI发生率和高风险患者医院获得性PI发生率等指标。结果 应用PI临床决策支持系统后,PI入院风险评估及时率从84.78%提高至95.94%,PI预防措施落实与风险评估合格率从90.15%提高至99.13%,PI护理记录缺陷率从16.42%下降至8.70%,与应用前比较,差异均有显著统计学意义（P<0.001）。系统应用后,医院获得性PI发生率和高风险患者医院获得性PI发生率均下降。结论 PI临床决策支持系统为护士提供准确、客观的决策依据,提高了护理质量及管理效率。
