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.
