Abstract:

Objective To develop an ICU patient disease severity grading nursing information system and evaluate its application effect，with the aim of optimizing human resources allocation and improving the quality of care for critically ill patients. Methods A research team was established to construct an ICU patient disease severity grading nursing information system through methods such as literature review，clinical investigation and expert consultation. The system consists of 3 modules，including disease severity grading，disease severity early warning and auxiliary decision-making. This system was officially applied in the ICU of a tertiary grade-A hospital in Shanghai in October 2023. The patients admitted in November 2023 were assigned to an experimental group，and those admitted in August 2023 were assigned to a control group. The correlation between the disease severity grading and Acute Physiology and Chronic Health Evaluation Ⅱ（APACHE Ⅱ） score was evaluated in the experimental group. Indicators including ICU nursing quality scores，the success rate of patient rescue，and length of ICU stay were compared between the 2 groups. Results The experimental group included 324 patients and the control group included 285 patients. In the experimental group，a positive correlation was observed between the disease severity grading result and the APACHE Ⅱ score（P<0.001）. Compared with the control group，the experimental group had higher ICU nursing quality score and the success rate of patient rescue，as well as a significantly shorter length of ICU stay（P<0.05）. Conclusion The use of the ICU patient condition grading nursing information system enables the classification of patient disease severity and the early warning of disease severity，which contributes to improve the quality of care，increase the success rate of patient rescue，and shorten the length of ICU stay for patients.

摘要：

目的 开发ICU患者病情分级护理信息系统，并评价其应用效果，旨在优化人力资源调配、改善危重症患者的护理质量。方法 成立研究小组，采用文献回顾、临床调研和专家论证等方法开发ICU患者病情分级护理信息系统，包括病情分级、病情预警、辅助决策3个模块。该系统于2023年10月在上海市某三级甲等医院ICU中正式应用，将2023年11月收治的患者作为试验组、2023年8月收治的患者作为对照组，评价试验组患者病情分级结果和急性生理与慢性健康状况评分Ⅱ结果的相关性，比较两组ICU护理质量评分、患者抢救成功率、ICU住院天数等指标。结果 试验组纳入324例患者，对照组纳入285例。试验组的患者病情分级结果与急性生理与慢性健康状况评分Ⅱ结果呈正相关（P<0.001）。试验组的ICU护理质量评分、患者抢救成功率均高于对照组，试验组的ICU住院天数少于对照组，差异具有统计学意义（P<0.05）。结论 使用ICU患者病情分级护理信息系统可实现病情分级和病情预警，有助于提升护理质量、提高患者抢救成功率、缩短ICU住院天数。
