Clusters of healthcare-associated SARS-CoV-2 infections in Norwegian hospitals detected by a fully automatic register-based surveillance system

The epidemiology of multidrug-resistant organisms in persons diagnosed with cancer in Norway, 2008–2018: expanding surveillance using existing laboratory and register data

“…As the capture and linkage of existing regional laboratory data and national register data may be automated, it may be possible to expand surveillance without increasing the resource requirements [ 15 ]. Previous work has shown how it is possible to expand surveillance to detect outbreaks and clusters in the healthcare setting through the use of automated algorithms to capture and link existing register data [ 16 , 17 ]. The challenges posed to such an expansion of surveillance include the need for standardised protocols to capture heterogenous laboratory data from multiple sources and ensure the privacy of the patient [ 15 ].…”

Innovative Techniques for Infection Control and Surveillance in Hospital Settings and Long-Term Care Facilities: A Scoping Review

“…For the 43 studies included in the analysis [55][56][57], most (n = 16) were published in the last year [11,15,17,18,20,21,26,[28][29][30]32,39,40,46,48,57], four in 2022 [24,31,34,42], six in 2021 [10,27,33,35,37,49], seven in 2020 [12,14,25,36,38,43,44], six in 2019 [13,22,23,41,55,56], and four in 2018 [16,19,45,47]. Despite the year of publication, we also observed the last year in which the study was conducted.…”

“…We observed that most of the studies were conducted in 2019 (n = 7, [10,18,20,31,37,41,57]), followed by 2017 (n = 6, [14,22,23,33,44,55,56]), 2018 (n = 6, [17,28,32,34,42,43]), and 2020 (n = 6, [11,15,21,26,27,48]). Only a few studies were conducted in earlier and later years (2021 = 4 [18,24,40,46]; 2022 = 3 [29,30,39]; 2016 = 1 [16]; 2015 = 3 [35,36,38]; 2014 = 1 [19]; 2013 = 2 [12,49]; 2012 = 1 [45]; 2010 = 1 [13]; Unknown = 1 [47]). The mean duration of the studies was 43.7 months (median 38.5; IQR 12-68).…”

“…The mean duration of the studies was 43.7 months (median 38.5; IQR 12-68). The studies were conducted across multiple continents, with sixteen conducted in North America (fourteen in the US [10,14,16,17,19,20,23,34,38,42,[45][46][47]55] and two in Canada [26,35]); twenty-one in Europe (six in the UK, [24,27,29,30,36,57], four in Sweden [12,15,21,49], three in Germany [28,41,44], two in France [13,32] and Italy [37,43], and one each in the Netherlands [56], Spain [40], Norway [39], and Switzerland [11]); five in Asia (three in China [18,25,31], one in Pakistan [48], and one in Thailand [22]), and one in Africa (Rwanda [33]). The majority of studies were single-centre studies (n = 26, [10,11,1...…”

“…Among the studies, 19 reported data from more or all hospital wards [10][11][12][13]15,16,24,25,29,[34][35][36]39,41,[44][45][46]49,57], while the rest collected data from specific wards: sixteen from single surgical wards (one paediatric [43], seven orthopaedic [18,23,26,32,40,55,56], three abdominal [21,27,48], one cardiac [30], three neurosurgical [17,22,31], one gynaecology [33]); four from ICUs [19,28,37,42]; and four from other wards [14,20,38,47]. Among the studies, 19 reported data from more or all hospital wards [10][11][12][13]15,…”
