基于合并症的RSV住院患者风险分层优于单纯年龄标准
本研究纳入334名PCR确诊RSV急性呼吸道感染住院患者的多中心队列数据，评估现有年龄分层标准预测ICU/HDU入住或60天死亡的效能。结果显示单纯年龄阈值（≥75岁或≥60岁）区分度有限（AUC 0.58-0.61），而纳入年龄、COPD、癌症史及痴呆的模型AUC明显提高。
要点
- 单纯年龄标准（≥75岁或≥60岁）预测RSV患者ICU入住或60天死亡的AUC仅0.58-0.61
- 纳入COPD、癌症史、痴呆等合并症的模型预测效能显著优于年龄标准
- 现行基于年龄的RSV疫苗接种资格建议可能需要结合合并症调整
核心结论
- 单纯年龄阈值（≥75岁或≥60岁）对RSV住院患者预后的区分能力有限（AUC 0.58-0.61）
- 整合年龄、COPD、癌症史及痴呆的临床模型可显著提高预测效能
研究设计与样本
- 多中心队列研究，纳入334名PCR确诊RSV急性呼吸道感染住院患者
主要发现
- 年龄≥75岁或≥60岁阈值预测ICU/HDU入住或60天死亡的优化校正AUC为0.58-0.61
- 纳入COPD、癌症（现患或既往）、痴呆的模型AUC高于单纯年龄标准
临床怎么用
- RSV住院患者风险评估应综合考虑COPD、癌症史、痴呆等合并症，而非仅依据年龄
- 现行年龄分层的RSV疫苗接种建议可能需结合重要合并症重新评估

Tommaso Morelli and colleagues present a timely and methodologically robust study that sheds new light on how risk (for poor outcome) could be assessed in adults hospitalised with respiratory syncytial virus (RSV) infection in the UK. 1 Using data from a multicentre cohort of 334 patients with PCR-confirmed RSV-related acute respiratory infection, the authors critically evaluate the relevance of existing age-based thresholds used by the Joint Committee on Vaccination and Immunization for guiding RSV vaccine eligibility. Their findings show that simple age-based cut-offs applied currently, such as ≥75 years (or even ≥60 years), offer only limited discriminatory power for predicting Intensive Care Units (ICU)/High Dependency Units (HDU) admission or 60-day mortality, with optimism-adjusted AUCs between 0.58 and 0.61. By contrast, a more clinically nuanced model incorporating age, chronic obstructive pulmonary disease (COPD), current or past cancer and dementia yielded a considerably higher area under the curve (AUC) of...
