OBJECTIVES
Several publications have demonstrated increased 30-day mortality in patients admitted on Saturdays or Sundays compared with weekdays. We sought to determine whether this was true for two different cohorts of patients admitted with acute myocardial infarction (MI).
METHODS AND RESULTS
Thirty-day mortality data were obtained for 3757 patients who had been admitted to the Belfast Health and Social Care Trust with acute MI between 2009 and 2015. They were subdivided into those presenting with ST elevation MI (n=2240) and non-ST elevation MI (n= 1517). We observed no excess 30-day mortality in those admitted over weekends.
CONCLUSION
Excess mortality in patients admitted at weekends is not a universal finding. This may mean that that there are patient subgroups with proportionately greater weekend hazard and points to the need for more detailed understanding of the weekend effect.
目的
多项研究表明，与工作日入院的患者相比，周六或周日入院的患者30天死亡率更高。我们试图确定这一情况对于两组不同的急性心肌梗死（MI）入院患者是否同样成立。
方法与结果
获取了2009年至2015年间因急性心肌梗死入住贝尔法斯特健康与社会护理信托基金的3757例患者的30天死亡率数据。这些患者被分为ST段抬高型心肌梗死患者（n = 2240）和非ST段抬高型心肌梗死患者（n = 1517）。我们观察到周末入院的患者30天死亡率并无增加。
结论
周末入院患者死亡率过高并非普遍现象。这可能意味着存在部分患者亚组，其周末风险相对更高，也表明有必要更深入地了解周末效应。
