症状监测系统使用急诊科（艾德）数据来检测流感爆发的兴趣一直在增长。对这些系统的评价通常侧重于流感季节期间的事件。本研究的目的是确定哪些急诊科疾病代码与确诊的流感病例最相关，并确定这些代码在非流感季节是否有用。2009年在澳大利亚维多利亚发生的流感大流行为检查该事件期间症状监测系统的性能提供了进一步的机会。我们进行了回顾性分析的数据从维多利亚州卫生部的试点综合征监测计划，“SynSurv”。SynSurv自动捕获艾德工作人员输入的患者信息。这些信息包括患者的人口统计数据，他们的症状和初步诊断使用ICD-10编码。为了确定哪些代码与流感通知最相关，计算了数据集中曾经使用过的每个ICD-10诊断代码的每周计数，并与相应的每周确诊流感病例计数进行了比较。然后进行了这些代码与非流感季节确诊流感病例之间的相关性。数据涵盖2001年7月至2009年8月期间，包括2009年流感大流行。在流感大流行期间，实验室确认的流感病例和相关ICD-10编码的每周计数均显著增加。实验室确诊病例的增加是2007年报告的最高数字的四倍多，尽管社区的流感样疾病活动被认为与2003年和2007年相当。我们发现5个ICD-10编码与流感病例中度和显著相关。这些代码与流感季节以外的实验室确认流感通知无关，至少部分原因是在此期间报告的流感病例数量较少。这项研究表明，艾德工作人员记录流感样疾病病例的代码选择受到他们对当时流感流行程度的看法的影响。由于病例诊断受艾德工作人员认为社区正在发生的情况的影响，症状监测早期发现疫情的能力可能受到阻碍。
Interest in the use of emergency department (ED) data by syndromic surveillance systems to detect influenza outbreaks has been growing. Evaluations of these systems generally focus on events during influenza seasons. The aims of this study were to identify which emergency department disease codes best correlated with confirmed influenza cases and to determine if these same codes would be useful in the non-influenza season. The 2009 influenza pandemic in Victoria, Australia, provided further opportunity to examine the performance of the syndromic surveillance system during this event. We undertook a retrospective analysis of data from the Victorian Department of Health's pilot syndromic surveillance programme, 'SynSurv'. SynSurv automatically captures patient information as it is entered by ED staff. This information includes patient demographics, their presenting symptoms and a preliminary diagnosis using ICD-10 coding. To determine which codes were best correlated with influenza notifications, weekly counts for each of the ICD-10 diagnosis codes ever used in the dataset were calculated and compared with the corresponding weekly count of confirmed influenza cases. Correlations between these codes and confirmed influenza cases in the non-influenza season were then undertaken. The data covered the period from July 2001 until August 2009 and included the 2009 influenza pandemic. There was a marked increase in weekly counts of both laboratory-confirmed influenza cases and relevant ICD-10 codes during the influenza pandemic period. The increase in laboratory confirmed cases was more than four times greater than the previous highest number reported, in 2007, even though the influenza-like-illness activity in the community was considered comparable to 2003 and 2007. We found five ICD-10 codes to be moderately and significantly correlated with influenza cases. None of these codes was correlated with laboratory confirmed influenza notifications outside the influenza season, at least in part because of the small number of influenza cases notified during that period. This study suggests that the choice of codes made by ED staff to record a case of influenza-like illness is influenced by their perceptions of how much influenza is circulating at the time. The ability of syndromic surveillance to detect outbreaks early may be impeded because case diagnosis is influenced by what ED staff believes to be occurring in the community.
