Limited research exists on the effectiveness of the New Zealand Early Warning Score (NZEWS).
To determine the impact of a modified NZEWS (M-NZEWS) and NZEWS on ward patients' medical emergency team activation triggers.
Mixed methods sequential design.
Three phases included: 1) review of M-NZEWS electronic data to determine the effect of a M-NZEWS and NZEWS on ward patients; 2) an in-depth review of 20 Māori patients allocated to lower escalation zones if the NZEWS were adopted and 3) the number of electronic medical emergency team activation triggers compared to the number of actual medical emergency team activations.
1255 patients and 3505 vital sign data sets were analysed. Adopting the NZEWS would result in 396 (26.8%) fewer patients triggering a medical emergency team activation. The biggest impact would be on Māori, with 38.6% of Māori allocated to a lower escalation zone. Only 51.2% of patients with a medical emergency team activation had vital signs triggering the response electronically documented.
Changing from the M-NZEWS to NZEWS will reduce the number of medical emergency team activation triggers, with the biggest impact on Māori. Electronic vital sign data does not accurately reflect the number of ward medical emergency team triggers or activations.
关于新西兰早期预警评分（NZEWS）的有效性的研究有限。
确定改良新西兰早期预警评分（M-NZEWS）和 NZEWS 对病房患者医疗急救团队激活触发因素的影响。
混合方法序贯设计。
包括三个阶段：1）审查 M-NZEWS 电子数据，以确定 M-NZEWS 和 NZEWS 对病房患者的影响；2）深入审查如果采用 NZEWS，被分配到较低升级区的 20 名毛利患者；3）与实际医疗急救团队激活次数相比，电子医疗急救团队激活触发次数。
分析了 1255 名患者和 3505 个生命体征数据集。采用 NZEWS 将导致 396 名（26.8%）患者的医疗急救团队激活触发减少。对毛利人影响最大，38.6%的毛利人被分配到较低的升级区。只有 51.2%的医疗急救团队激活患者的生命体征电子记录触发了反应。
从 M-NZEWS 改为 NZEWS 将减少医疗急救团队激活触发的数量，对毛利人的影响最大。电子生命体征数据不能准确反映病房医疗急救团队触发或激活的数量。
