An emergency department providing critical care will have an effect on outcome and intensive-care-units' resources by avoiding unnecessary or futile intensive-care admissions and thereby save hospital expenses. The study focussed on this result.
The study employed a retrospective analysis of prospectively collected data of out-of-hospital cardiac arrest patients with return of spontaneous circulation, comatose on arrival. Outcomes and length of stay of patients who either stayed at the 'emergency department only' or were 'transferred in addition to an intensive care unit' were compared. Linear regression with log length of stay as outcome and 'emergency department only' as predictor with covariates was used for modelling.
From 1991 to 2008, out of 1236 patients (age 57 ± 15 years, female 31%), the 'emergency department only' group (n=349 (28%)) survived to discharge in 81(23%) cases, with a median length-of-stay in critical care of 1.7 (interquartile range 0.8; 3.1) days. The patients 'transferred in addition to an intensive care unit' (n=887 (72%)), with a survival rate of 55% (n=486, p<0.001) stayed 10 (5; 18) days (p<0.001). The length-of-stay in hospital was significantly shorter if patients were treated in the 'emergency department only' independent of other cardiac-arrest-related factors (regression coefficient -1.42, confidence interval -1.60 to -1.24).
An emergency department with critical care prevents admissions to intensive care units in 28% of patients with out-of-hospital cardiac arrest. It saves intensive-care-unit resources and shortens length of stay for comatose out-of-hospital cardiac-arrest survivors, regardless of their outcome.
提供重症监护的急诊部门可以通过避免不必要或无效的重症监护入院来影响预后和重症监护病房的资源,从而节省医院费用。本研究聚焦于这一结果。
本研究采用回顾性分析,对有自主循环恢复、到达时昏迷的院外心脏骤停患者前瞻性收集的数据进行分析。比较仅在“急诊部”治疗和“除重症监护病房外还转科”的患者的结局和住院时间。采用对数住院时间为因变量,“仅在急诊部”为预测因子,并用协变量进行线性回归建模。
1991 年至 2008 年,在 1236 例患者(年龄 57 ± 15 岁,女性 31%)中,“仅在急诊部”组(n=349[28%])存活出院 81 例(23%),入住重症监护病房的中位数时间为 1.7(四分位间距 0.8;3.1)天。“除重症监护病房外还转科”的患者(n=887[72%]),存活率为 55%(n=486,p<0.001),住院时间为 10(5;18)天(p<0.001)。如果患者仅在“急诊部”治疗,独立于其他心脏骤停相关因素,住院时间明显缩短(回归系数-1.42,置信区间-1.60 至-1.24)。
对于院外心脏骤停患者,配备重症监护的急诊部可以防止 28%的患者转入重症监护病房。它可以节省重症监护病房的资源,并缩短昏迷的院外心脏骤停幸存者的住院时间,而与他们的结局无关。
