Abstract

BACKGROUND

We aimed to investigate the association between the time taken to start dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) and survival outcomes for OHCA.

METHODS

This was a retrospective analysis using the Singapore Pan-Asian Resuscitation Outcomes Study data between 2012 and 2021. We included all adult, witnessed, non-traumatic OHCA patients who received DA-CPR. The exposure of interest was time interval from emergency call to start of DA-CPR. Patients were divided into three groups based on previous studies. The outcome was defined as survival to 30-days with favorable neurological outcomes. Multivariable logistic regression analysis was performed. Restricted cubic spline curves were used to explore non-linear relationships.

RESULTS

3,861 OHCA patients were included in this analysis. Patients were grouped as follows: short (0-179 s), medium (180-239 s), and long (≥240 s) to start DA-CPR. Adjusted odds ratios [95% CI] for survival to 30-days with favorable neurological outcomes were: medium 0.82 [0.52-1.28], long 0.63 [0.40-0.98]. The restricted cubic spline curve showed a monotonic decrease in the odds ratio for survival to 30-days with favorable neurological outcomes.

CONCLUSIONS

This study found that among non-traumatic, witnessed OHCA patients who received DA-CPR, a shorter time to start DA-CPR was associated with better 30-day survival with favorable neurological outcomes.

摘要

背景

我们旨在研究调度员辅助心肺复苏(DA-CPR)开始时间与院外心脏骤停(OHCA)患者生存结局之间的关联。

方法

这是一项回顾性分析,使用了2012年至2021年新加坡泛亚复苏结局研究的数据。我们纳入了所有接受DA-CPR的成年、有目击者、非创伤性OHCA患者。感兴趣的暴露因素是从紧急呼叫到开始DA-CPR的时间间隔。根据先前的研究,将患者分为三组。结局定义为存活至30天且神经功能结局良好。进行了多变量逻辑回归分析。使用受限立方样条曲线来探索非线性关系。

结果

本分析纳入了3861例OHCA患者。患者按以下方式分组:开始DA-CPR的时间短(0-179秒)、中(180-239秒)和长(≥240秒)。存活至30天且神经功能结局良好的调整优势比[95%置信区间]为:中0.82[0.52-1.28],长0.63[0.40-0.98]。受限立方样条曲线显示,存活至30天且神经功能结局良好的优势比呈单调下降。

结论

本研究发现,在接受DA-CPR的非创伤性、有目击者的OHCA患者中,开始DA-CPR的时间越短,30天存活且神经功能结局良好的可能性越大。
