CDC NHSN医院呼吸道数据（HRD）是一个由美国疾病控制与预防中心（CDC）国家医疗安全网络（NHSN）收集的公开数据集，专注于医院呼吸道疾病监测。数据集覆盖时间从2020年8月8日至2026年4月18日，以每周为频率更新，包含美国国家级、次国家级区域和州级（共67个唯一位置ID）的数据。数据涉及三种主要呼吸道病原体：流感、SARS-CoV-2（COVID-19）和RSV。关键数据列包括新实验室确认的流感、COVID-19和RSV住院人数（每周）、床位容量和占用情况（如总配备住院床位、ICU床位占用）、ICU患者数以及按人口标准化的住院率。此外，数据集还提供季节性累计住院人数。从2024-25季节开始，该数据集作为FluSight预测中心的评分目标。数据收集在2024年11月从自愿报告转为强制报告，因此长期建模时需注意2024年11月前后数据收集制度的变化。数据集还包括解释性注意事项，例如床位计数仅包括配备人员的床位，RSV数据在2024年第46周前为自愿报告可能不完整。数据可用于呼吸道疾病趋势分析、预测模型评估和公共卫生监测。

CDC NHSN Hospital Respiratory Data (HRD) is a public dataset collected by the U.S. Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN), dedicated to hospital-based respiratory disease surveillance. The dataset spans from August 8, 2020 to April 18, 2026, with weekly updates, and contains data at the U.S. national, subnational regional, and state levels, totaling 67 unique location IDs. It covers three primary respiratory pathogens: influenza, SARS-CoV-2 (COVID-19), and RSV. Key data columns include weekly counts of newly laboratory-confirmed influenza, COVID-19, and RSV hospitalizations; bed capacity and occupancy metrics (e.g., total staffed inpatient beds, ICU bed occupancy); numbers of ICU patients; and population-standardized hospitalization rates. Additionally, the dataset provides seasonal cumulative hospitalization counts. Starting from the 2024-25 season, this dataset has functioned as a scoring target for the FluSight Forecast Hub. Data collection was transitioned from voluntary reporting to mandatory reporting in November 2024; thus, researchers should note the change in data collection protocols before and after November 2024 when performing long-term modeling. The dataset also includes explanatory caveats: for instance, bed counts only encompass staffed beds, and RSV data was voluntarily reported prior to Week 46 of 2024 and may be incomplete. This dataset is applicable for respiratory disease trend analysis, predictive model evaluation, and public health surveillance.
