Abstract: Objective  To analyze the application effect of pressure injury intelligent "assessment-decision-control" system in severe patients with cerebrovascular disease. 
Methods  The pressure injury management system was optimized, and the severe cerebrovascular disease patients (2448 cases) before system optimization (January 2018-December 2019) were selected as the control group, and the severe cerebrovascular disease patients (3547 cases) after system optimization (January 2020-December 2021) were selected as the observation group. The rate of pressure injury assessment, accuracy rate of risk assessment, accuracy rate of wound assessment, correct rate of wound treatment, and incidence of in-hospital pressure injury within 2 hours of admission were compared between the two groups.
Results  The above indexes results between the two groups were as follows (control vs. observation): the rate of pressure injury assessment was 94.7% vs. 99.0% (χ2=7.3, P=0.007); the correct rate of risk assessment was 89.0% vs. 96.3% (χ2=11.9, P=0.001); the correct rate of wound assessment was 74.0% vs. 90.0% (χ2=4.3, P=0.037); the correct rate of wound treatment was 84.0% vs. 96.0% (χ2=4.0, P=0.046), with all the above differences having statistical significance (P<0.05). The incidence of in-hospital pressure injury in the control group was 0.04% (1/2448), while that in the observation group was 0 (0/3547).
Conclusions  The "assessment-decision-control" system for stress injury can help nurses to assess, judge and record stress injury correctly, and make reasonable clinical nursing decisions.

摘要： 目的 分析压力性损伤智能化“评估-决策-控制”系统在脑血管病重症患者中的应用效果。
方法 对压力性损伤管理系统进行智能优化，将系统优化前（2018年1月-2019年12月）应用患者（2448例）设置为对照组，系统优化后（2020年1月-2021年12月）应用患者（3547例）设置为观察组，比较两组患者入科2 h内压力性损伤评估完成率、风险评估准确率、伤口评估准确率、伤口处理正确率、院内压力性损伤发生率的差异。
结果 对照组和观察组患者入科2 h内压力性损伤风险评估完成率分别为94.7%和99.0%（χ2=7.3，P=0.007），风险评估准确率分别为89.0%和96.3%（χ2=11.9，P=0.001），伤口评估准确率分别为74.0%和90.0%（χ2=4.3，P=0.037），伤口处理正确率分别为84.0%和96.0%（χ2=4.0，P=0.046），差异均有统计学意义。对照组院内压力性损伤发生率为0.04％（1/2448），观察组院内压力性损伤发生率为0（0/3547）。
结论 压力性损伤智能化“评估-决策-控制”系统，可以帮助护士准确评估、判断和记录压力性损伤，并做出合理的临床护理决策。
