Abstract:

Objective　To evaluate the application effect of visualization system and whole process management in CT enhanced examination. Methods　A total of 5 197 patients who underwent enhanced CT examination in the Department of Radiology of the Third People's Hospital of Hubei Province from June 2022 to July 2023 were selected by the convenience sampling method as the study objects. From June 2022 to November 2022, 2 249 patients were selected a control group, including 1 349 males and 900 females, aged (58.32±1.25) years. From February 2023 to July 2023, 2 948 patients were selected an intervention group, including 1 713 males and 1 235 females, aged (54.08±2.47) years. The control group received routine nursing procedures, while the intervention group received visualization system and whole process management. The incidence of contrast agent extravasation, extravasation degree, edema remission time, image quality score (Likert score scale), and patient satisfaction (self-made questionnaire) were compared between the two groups. Independent sample t test, χ² test, and rank sum test were used for statistical analysis. Results　The incidence of contrast agent extravasation in the intervention group was lower than that in the control group [0.37% (11/2 948) vs. 0.89% (20/2 249)] (P<0.05). The degree of contrast agent extravasation in the intervention group was better than that in the control group (P<0.05). The complete remission time of edema in the intervention group was shorter than that in the control group [(31.56±1.74) h vs. (49.83±5.12) h] (P<0.05). The scores of image quality and patient satisfaction in the intervention group were higher than those in the control group [(4.81±0.33) points vs. (4.25±0.53) points, (9.12±0.29) points vs. (8.32±0.46) points] (both P<0.05). Conclusion　The combination of visualization system and whole process management can effectively improve the safety and quality of CT enhanced examination, provide a new reference mode for clinical nursing management, and has positive significance for improving patient experience and radiation nursing quality.

摘要：

目的　评估可视化系统结合全流程规范化管理在CT增强检查中的应用效果。方法　采用便利抽样法，选取2022年6月至2023年7月在湖北省第三人民医院放射科行CT增强检查的5 197例患者作为研究对象。2022年6月至2022年11月2 249例为对照组，其中男1 349例，女900例；年龄（58.32±1.25）岁。2023年2月至2023年7月2 948例为干预组，其中男1 713例，女1 235例；年龄（54.08±2.47）岁。对照组采用CT增强检查常规护理，干预组采用全流程、规范化护理。比较两组对比剂外渗发生率、外渗程度、水肿消退时间、影像质量（Likert评分量表）、满意度（自制调查问卷）。采用独立样本t检验、χ²检验和秩和检验进行统计学分析。结果　干预组对比剂外渗发生率低于对照组［0.37%（11/2 948）比0.89%（20/2 249）］（P<0.05）。干预组对比剂外渗程度优于对照组（P<0.05）。干预组水肿完全消退时间短于对照组［（31.56±1.74）h比（49.83±5.12）h］（P<0.05）。干预组影像质量及满意度评分均高于对照组［（4.81±0.33）分比（4.25±0.53）分、（9.12±0.29）分比（8.32±0.46）分］（均P<0.05）。结论　可视化系统结合全流程管理可有效提高CT增强检查质量和安全性，对改善患者体验和放射护理质量具有积极意义。
