Aim

To develop and validate a model for the early prediction of long-term neurological outcome in patients with non-traumatic out-of-hospital cardiac arrest (OHCA).

Methods

We analysed multicentre OHCA registry data of adult patients with non-traumatic OHCA who experienced return of spontaneous circulation (ROSC) and had been admitted to the intensive care unit between 2013 and 2017. We allocated 1329 (2013–2015) and 1025 patients (2016–2017) to the derivation and validation sets, respectively. The primary outcome was the dichotomized cerebral performance category (CPC) at 90 days, defined as good (CPC 1–2) or poor (CPC 3–5). We developed 2 models: model 1 included variables without laboratory data, and model 2 included variables with laboratory data available immediately after ROSC. Logistic regression with least absolute shrinkage and selection operator regularization was employed for model development. Measures of discrimination, accuracy, and calibration (C-statistics, Brier score, calibration plot, and net benefit) were assessed in the validation set.

Results

The C-statistic (95% confidence intervals) of models 1 and 2 in the validation set was 0.947 (0.930–0.964) and 0.950 (0.934–0.966), respectively. The Brier score of models 1 and 2 in the validation set was 0.0622 and 0.0606, respectively. The calibration plot showed that both models were well-calibrated to the observed outcome. Decision curve analysis indicated that model 2 was similar to model 1.

Conclusion

The prediction tool containing detailed in-hospital information showed good performance for predicting neurological outcome at 90 days immediately after ROSC in patients with OHCA.

院外心脏骤停患者自主循环恢复后 90 天神经功能早期预测的开发和验证

目标

开发和验证用于早期预测非创伤性院外心脏骤停 (OHCA) 患者长期神经系统结果的模型。

方法

我们分析了 2013 年至 2017 年间经历自主循环恢复 (ROSC) 并入住重症监护病房的非创伤性 OHCA 成年患者的多中心 OHCA 登记数据。我们分配了 1329 名(2013 年至 2015 年)和 1025 名患者(2016 年) –2017) 分别用于推导和验证集。主要结果是 90 天时的二分大脑表现类别 (CPC),定义为好 (CPC 1-2) 或差 (CPC 3-5)。我们开发了 2 个模型:模型 1 包括没有实验室数据的变量,模型 2 包括在 ROSC 后立即可用的实验室数据的变量。模型开发采用具有最小绝对收缩和选择算子正则化的逻辑回归。辨别力、准确性和校准的措施(C 统计量、Brier 分数、校准图、

结果

验证集中模型 1 和 2 的 C 统计量(95% 置信区间)分别为 0.947(0.930–0.964)和 0.950(0.934–0.966)。验证集中模型 1 和 2 的 Brier 分数分别为 0.0622 和 0.0606。校准图表明,两种模型都很好地校准到观察到的结果。决策曲线分析表明模型 2 与模型 1 相似。

结论

包含详细住院信息的预测工具在预测 OHCA 患者 ROSC 后 90 天的神经系统结果方面表现出良好的性能。
