目的：我们评估的有用性和准确性的媒体报道的数据，主动灾害相关的死亡率surveillance.Methods：从2012年10月29日至11月5日，从疾病控制和预防中心（CDC）的流行病学家跟踪在线媒体报道的飓风桑迪相关的死亡，通过使用关键字搜索。为了评价媒体报道的数据，将Sandy相关死亡的生命统计记录与相应的媒体报道的死亡进行比较，并评估匹配百分比。敏感性，阳性预测值（PPV），和及时的媒体报道检测桑迪相关的deaths.Results：九十九媒体报道的死亡被确定和比较发送到疾病预防控制中心的人口动态统计死亡记录由纽约市（NYC）和5个州同意参加这项研究。75份（76%）媒体报道与人口动态统计记录相符。只有纽约市能够积极跟踪桑迪相关的死亡事件期间。中度敏感性（83%）和PPV（83%）计算匹配媒体报道的死亡NYC.Conclusions：在飓风桑迪，媒体报道的信息是中度敏感性，与生命统计记录的匹配百分比也是中等。研究结果表明，在线媒体报道的死亡人数可以作为一个补充信息来源，在灾害的初始响应阶段的情况意识和立即的公共卫生决策是有用的。
Objective: We evaluated the usefulness and accuracy of media-reported data for active disaster-related mortality surveillance.Methods: From October 29 through November 5, 2012, epidemiologists from the Centers for Disease Control and Prevention (CDC) tracked online media reports for Hurricane Sandy-related deaths by use of a keyword search. To evaluate the media-reported data, vital statistics records of Sandy-related deaths were compared to corresponding media-reported deaths and assessed for percentage match. Sensitivity, positive predictive value (PPV), and timeliness of the media reports for detecting Sandy-related deaths were calculated.Results: Ninety-nine media-reported deaths were identified and compared with the 90 vital statistics death records sent to the CDC by New York City (NYC) and the 5 states that agreed to participate in this study. Seventy-five (76%) of the media reports matched with vital statistics records. Only NYC was able to actively track Sandy-related deaths during the event. Moderate sensitivity (83%) and PPV (83%) were calculated for the matching media-reported deaths for NYC.Conclusions: During Hurricane Sandy, the media-reported information was moderately sensitive, and percentage match with vital statistics records was also moderate. The results indicate that online media-reported deaths can be useful as a supplemental source of information for situational awareness and immediate public health decision-making during the initial response stage of a disaster.
