Abstract
The Royal College of Physicians (RCP) recently published the National Early Warning Score 2 (NEWS2), aiming to improve safety for patients with hypercapnic respiratory failure by suggesting a separate oxygen saturation (SpO) parameter scoring system for such patients. A previously published study of patients (n=2,361 admissions) with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) demonstrated alternative scoring systems at admission did not outperform the original NEWS. Applying NEWS2 SpO parameters to this previously described cohort would have resulted in 44% (n=27/62) of patients who scored ≥7 points on the original NEWS and subsequently died being placed in a lower call-out threshold. NEWS2 loses the benefits of a unified, standardised scoring system and we suggest prospective research in this area before applying this adjustment.
摘要
皇家内科医师学院（RCP）最近发布了国家早期预警评分 2 版（NEWS2），旨在通过为高碳酸血症性呼吸衰竭患者提出单独的血氧饱和度（SpO2）参数评分系统来提高患者安全性。此前对患有慢性阻塞性肺疾病急性加重（AECOPD）的患者（n=2361 例入院患者）的一项研究表明，入院时的替代评分系统并未优于原始 NEWS。将 NEWS2 的 SpO2 参数应用于之前描述的队列中，将导致原始 NEWS 评分≥7 分且随后死亡的 44%（n=27/62）患者被置于较低的呼叫阈值。NEWS2 失去了统一、标准化评分系统的优势，我们建议在应用此调整之前在该领域进行前瞻性研究。
