在MRI过程中患者的运动不成比例地影响着老年人,男性,黑人患者和肥胖患者. 识别这些风险因素可以帮助提高MRI质量,减少与运动有关的问题.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 患者安全 患者安全
背景情况:
- 在临床磁共振成像 (MRI) 中,程序内患者运动是一个重大挑战,往往导致图像质量下降.
- 了解导致患者运动的因素对于制定减轻其影响的策略至关重要.
研究的目的:
- 评估临床特征和患者社会人口统计因素与MRI检查期间运动的发生之间的关联.
- 为了确定在MRI扫描期间运动风险较高的患者群体.
主要方法:
- 在美国两个城市卫生系统中,从2022年开始对68,517份MRI报告进行了回顾性审查.
- 运动是通过MRI报告中的提及来识别的. 从电子健康记录中提取了临床和社会人口统计数据.
- 多变量逻辑回归被用来分析关联,调整为护理环境.
主要成果:
- 紧急和住院MRI研究显示,与门诊检查相比,运动的概率明显更高.
- 年龄较大 (≥85岁),男性性别,黑人种族和肥胖增加 (II和III类) 独立地与更高的运动概率有关.
- 种族,喜欢的语言和医疗系统与运动没有显著的关联.
结论:
- 在MRI上的运动不成比例地影响特定的患者群体,包括老年人,男性,肥胖患者和黑人患者,无论在哪个护理环境.
- 将这些运动风险因素的知识纳入MRI调度,扫描前患者沟通和定位协议中,可能有助于减少运动限制研究.
- 通过工作流调整来解决这些差异对于确保所有患者群体提供公平,高质量的MRI服务至关重要.
