Abstract

Background: Interhospital transfer of ST-elevation myocardial infarction (STEMI) patients can lead to greater access to percutaneous coronary intervention (PCI) and reduce mortality. However, it is unclear how the characteristics of the transferring and receiving hospitals impacts mortality of transferred STEMI patients.

Methods: In this retrospective cohort study, we estimated differences in mortality among STEMI patients undergoing interhospital transfer using Kaplan-Meier survival curves and adjusted hazard ratios derived from Cox proportional hazard models.

Results: We found that partial PCI capability (i.e., retaining some patients while transferring others for PCI) of the transferring hospital and lower quality of the receiving hospital were associated with lower survival.

Conclusions: Interhospital transfers driven by factors other than distance and quality can negatively affect patient outcomes.

st段抬高型心肌梗死患者的转移和生存。

背景：st段抬高型心肌梗死（STEMI）患者的院间转移可导致更多的经皮冠状动脉介入治疗（PCI）并降低死亡率。然而，转院和接收医院的特点如何影响转院STEMI患者的死亡率尚不清楚。方法：在这项回顾性队列研究中，我们使用Kaplan-Meier生存曲线和Cox比例风险模型的校正风险比来估计STEMI住院转院患者的死亡率差异。结果：我们发现转诊医院的部分PCI能力（即保留部分患者而将其他患者转PCI）和接收医院的较低质量与较低的生存率相关。结论：由距离和质量以外的因素驱动的医院间转诊会对患者的预后产生负面影响。
