背景2003年，荷兰引入了对确诊的侵袭性脑膜炎球菌病（IMD）病例的加强监测，其中参考实验室数据（NRLBM）与通知数据（OSIRIS）相关联。监测信息的质量对公共卫生决策至关重要。我们的目标是描述该系统，并评估它的数据完整性和及时性。方法收集2004 - 2016年监测系统报告的病例。对于通知数据，我们使用血清型、疫苗接种状态、死亡率和感染国家的信息作为记录完整性的指标。区域和国家一级的通知时间是使用通知数据库中的报告日期计算的。结果2004-2016年共报告2123例，其中参考实验室报告1.968例（93%），通报系统报告1.995例（94%）。在所有病例中，1.840例病例（87%）在两个系统中报告，并且可能存在关联。在86%的通报病例中已知血清群，并且在2013-2016年期间显著较高（94%）。在报告的病例中，分别有88%、99%和97%的病例提供了关于疫苗接种状况、死亡率和感染国家的信息。86%的病例在一个工作日内得到区域通报，98%的病例在三天内得到全国通报。结论IMD监测系统表现良好，血清型完整性多年来有所提高。强调向临床和实验室监测系统报告的必要性对于进一步改善支持公共卫生应对和疫苗接种政策的总体业绩仍然很重要。
Background Enhanced surveillance for confirmed cases of invasive meningococcal disease (IMD) was introduced in the Netherlands in 2003, in which reference laboratory data (NRLBM) are linked with notification data (OSIRIS). The quality of surveillance information is important for public health decision making. Our objective was to describe the system and evaluate it for data completeness and timeliness. Methods Cases reported in the surveillance system from 2004 to 2016 were included. For the notification data, we used information on serogroup, vaccination status, mortality, and country of infection as indicators for record completeness. Notification times to regional and national level were calculated using the reported dates available in the notification database. Results A total of 2123 cases were reported in the years 2004-2016, of which 1.968 (93%) were reported by the reference laboratory and 1.995 (94%) in the notification system. Of all cases, 1.840 cases (87%) were reported in both systems and could be linked. The serogroup was known in 86% of the notified cases, and was significantly higher (94%) in the years 2013-2016. Information on vaccination status, mortality and country of infection was available in 88, 99 and 97% of notified cases, respectively. Regional notification of cases occurred within one working day for 86% of cases and 98% were notified nationally within three days. Conclusions A well performing IMD surveillance system was demonstrated and serogroup completeness has improved over the years. Underlining the need for reporting to both the clinical and laboratory surveillance system remains important to further improve the overall performance in supporting public health response and vaccination policy.
