概括

2020年修订允许在日本非训练设施中进行旋转性心脏切除术 (RA),但经皮肤冠状动脉干预 (PCI) 后的住院死亡率没有增加. 这项研究没有发现培训和非培训设施在PCI结果中存在显著差异.

科学领域:

心血管医学心血管医学
干预心脏病学干预心脏病学
医疗保健服务研究医疗服务研究

背景情况:

2020年4月,日本更新了在皮肤冠状动脉干预 (PCI) 期间使用旋转性心脏切除术 (RA) 的标准.
经过董事会认证的PCI操作员现在可以在没有手术支持 (非培训设施) 的低体积医院中进行RA.

研究的目的:

评估2020年RA设施标准修订对医院PCI结果的影响.
特别调查新获许可使用RA的非培训设施的结果.

主要方法:

对J-PCI注册表 (2019-2023) 的回顾性分析,涉及超过110万个PCI.
准实验性的差异分析,比较2020年标准修订前后的培训和非培训设施.
主要结局:PCI后的住院死亡率.

主要成果:

在PCI期间,RA使用率从4.2% (2019) 增加到5.2% (2023).
在培训 (1.6%至1.9%) 和非培训 (1.7%至1.9%) 设施中,住院死亡率略有上升.
在修订后,设施类型之间的死亡率趋势没有显著差异 (调整后P = 0.55).

结论:

2020年RA设施标准的修订并没有显著增加低容量,非培训设施的医院内死亡率.
在新认可的非培训设施和已建立的培训设施之间,PCI结果仍然可比.

关键词:

冠状动脉切除术是指冠状动脉的切除术.差异中的差异分析分析.在医院的死亡率.观察到预期事件的比率.旋转性切除术是一种切除术.
