Three different data sources exist for monitoring COVID-19-associated hospitalisations in Norway: The Directorate of Health, the Norwegian Intensive Care and Pandemic Registry (NIPaR), and the linking of the Norwegian Patient Registry (NPR) and the Norwegian Surveillance System for Communicable Diseases (MSIS). A comparison of results from different data sources is important to increase understanding of the data and to further optimise current and future surveillance. We compared results from the three data sources from March to June 2020.
We analysed the number of new admissions, as well as the total number of hospitalised patients and those on ventilatory support, reported per day and by regional health authority. The analysis was descriptive.
The cumulative number of new admissions according to NPR-MSIS (n=1260) was higher than NIPaR (n=1153). The discrepancy was high early in the epidemic (93 as of 29 March). The trend in the number of hospitalised patients was similar for all three sources throughout the study period. NPR-MSIS overestimated the number of hospitalised patients on ventilatory support.
The discrepancy in new admissions between NIPaR and NPR-MSIS is primarily due to missing registrations for some patients admitted before NIPaR became operational. Basic information retrieved daily by the Directorate of Health give comparable results to more comprehensive daily information retrieval undertaken in NIPaR and NPR-MSIS, adjusted retrospectively. Further analysis is necessary regarding whether NIPaR and NPR-MSIS provide timely data and function as required in an emergency preparedness situation.
挪威存在三种不同的数据源用于监测与新冠病毒相关的住院情况：卫生署、挪威重症监护和大流行登记处（NIPaR），以及挪威患者登记处（NPR）与挪威传染病监测系统（MSIS）的关联数据。比较不同数据源的结果对于增进对数据的理解以及进一步优化当前和未来的监测工作至关重要。我们比较了2020年3月至6月这三种数据源的结果。
我们分析了按地区卫生当局每日报告的新入院人数、住院患者总数以及接受通气支持的患者人数。分析采用描述性方法。
根据NPR-MSIS统计的新入院累计人数（n = 1260）高于NIPaR（n = 1153）。在疫情早期差异较大（截至3月29日为93例）。在整个研究期间，所有三种数据源的住院患者数量趋势相似。NPR-MSIS高估了接受通气支持的住院患者人数。
NIPaR与NPR-MSIS在新入院人数上的差异主要是由于NIPaR开始运作之前入院的部分患者登记缺失。卫生署每日获取的基本信息与NIPaR和NPR-MSIS进行的更全面的每日信息检索（经回顾性调整）结果相当。关于NIPaR和NPR-MSIS是否能提供及时数据以及在应急准备情况下是否按要求发挥作用，还需要进一步分析。
