The changing spectrum of microbial aetiology of respiratory tract infections in hospitalized patients before and during the COVID-19 pandemic
Serigstad, Sondre; Markussen, Dagfinn Lunde; Ritz, Christian; Ebbesen, Marit Helen; Knoop, Siri Tandberg; Kommedal, Øyvind; Heggelund, Lars; Ulvestad, Elling; Bjørneklett, Rune Oskar; Grewal, Harleen (Journal article; Peer reviewed, 2022-09-30)Background: The COVID-19 pandemic was met with strict containment measures. We hypothesized that societal infection control measures would impact the number of hospital admissions for respiratory tract infections, as well ... -
Comparison of rapid molecular testing methods for detecting respiratory viruses in emergency care: a prospective study
Markussen, Dagfinn Lunde; Grewal, Harleen; Knoop, Siri Tandberg; Serigstad, Sondre; Kommedal, Øyvind; Ebbesen, Marit Helen; Ulvestad, Elling; Bjørneklett, Rune Oskar (Journal article; Peer reviewed, 2022)Background Respiratory tract infections (RTIs) caused by contagious viruses are common among patients presenting to the emergency department (ED). Early detection of these viruses can help prevent nosocomial transmissio ... -
The diagnostic utility of microscopic quality assessment of sputum samples in the era of rapid syndromic PCR testing
Markussen, Dagfinn Lunde; Ebbesen, Marit Helen; Serigstad, Sondre; Knoop, Siri Tandberg; Ritz, Christian; Bjørneklett, Rune Oskar; Kommedal, Øyvind; Jenum, Synne; Ulvestad, Elling; Grewal, Harleen (Journal article; Peer reviewed, 2023)This prospective study assessed the value of initial microscopy evaluation of sputum samples submitted for rapid syndromic PCR-based testing. Bacterial detections by the BioFire FilmArray Pneumonia Panel plus in 126 high- ... -
Diagnostic utility of oropharyngeal swabs as an alternative to lower respiratory tract samples for PCR-based syndromic testing in patients with community-acquired pneumonia
Serigstad, Sondre; Knoop, Siri Tandberg; Markussen, Dagfinn Lunde; Ulvestad, Elling; Bjørneklett, Rune Oskar; Ebbesen, Marit Helen; Kommedal, Øyvind; Grewal, Harleen (Journal article; Peer reviewed, 2023)Syndromic PCR-based analysis of lower respiratory tract (LRT) samples in patients with community-acquired pneumonia (CAP) improves the bacterial yield and time-to-results compared to culture-based methods. However, obtaining ... -
The epidemiology and characteristics of sepsis in Norwegian hospitals
Knoop, Siri Tandberg (Doctoral thesis, 2018-06-08)Background: Sepsis develops when the host’s immune response to infection becomes dysregulated to such an extent that life-threatening organ dysfunction evolves. Sepsis epidemiology is influenced by population characteristics, ... -
Epidemiology and impact on all-cause mortality of sepsis in Norwegian hospitals: A national retrospective study
Knoop, Siri Tandberg; Skrede, Steinar; Langeland, Nina; Flaatten, Hans (Peer reviewed; Journal article, 2017-11-17)Background: Although sepsis is the leading cause of death from infection, there are few population-level epidemiological sepsis reports. The impact of sepsis-related deaths on all-cause hospital mortality is insufficiently ... -
Impact of rapid molecular testing on diagnosis, treatment and management of community-acquired pneumonia in Norway: a pragmatic randomised controlled trial (CAPNOR)
Serigstad, Sondre; Ritz, Christian; Faurholt-Jepsen, Daniel; Markussen, Dagfinn Lunde; Ebbesen, Marit Helen; Kommedal, Øyvind; Bjørneklett, Rune Oskar; Heggelund, Lars; Clark, Tristan W.; van Werkhoven, Cornelis H.; Knoop, Siri Tandberg; Ulvestad, Elling; Grewal, Harleen (Journal article; Peer reviewed, 2022)Background: Community-acquired pneumonia (CAP) causes a large burden of disease. Due to difficulties in obtaining representative respiratory samples and insensitive standard microbiological methods, the microbiological ... -
Long-term temporal trends in incidence rate and case fatality of sepsis and COVID-19-related sepsis in Norwegian hospitals, 2008-2021: a nationwide registry study
Skei, Nina Vibeche; Nilsen, Tom Ivar Lund; Knoop, Siri Tandberg; Prescott, Hallie; Lydersen, Stian; Mohus, Randi Marie; Brkic, Alen; Liyanarachi, Kristin Vardheim; Solligård, Erik; Damås, Jan Kristian; Gustad, Lise Tuset (Journal article; Peer reviewed, 2023)Objectives: To estimate temporal trends in incidence rate (IR) and case fatality during a 14-year period from 2008 to 2021, and to assess possible shifts in these trends during the COVID-19 pandemic. Setting: All Norwegian ... -
Rapid syndromic PCR testing in patients with respiratory tract infections reduces time to results and improves microbial yield
Serigstad, Sondre; Grewal, Harleen; Ebbesen, Marit Helen; Kommedal, Øyvind; Heggelund, Lars; van Werkhoven, Werkhoven; Faurholt-Jepsen, Daniel; Clark, T.W.; Ritz, Christian; Ulvestad, Elling; Bjørneklett, Rune Oskar; Knoop, Siri Tandberg; Ravn, P.; Markussen, Dagfinn Lunde (Journal article; Peer reviewed, 2022)Lack of rapid and comprehensive microbiological diagnosis in patients with community acquired pneumonia (CAP) hampers appropriate antimicrobial therapy. This study evaluates the real-world performance of the BioFire FilmArray ...
