A large international trial documented that Internet-based training in CRP point-of-care testing, in enhanced communication skills, or both reduced antibiotic prescribing at 3 months, with risk ratios (RRs) of 0.68, 0.53, 0.38, respectively. We report the longer-term impact in this ...

      Background: Outpatients with acute cough who expect, hope for or ask for antibiotics may be more unwell, benefit more from antibiotic treatment, and be more satisfied with care when they are prescribed antibiotics. Clinicians may not accurately identify those patients. Objective: To explore whether patient views (expecting, hoping for or asking for antibiotics) are associated with illness presentation ...
    • The Association Between Self-Reported Symptoms of Recent Airway Infection and CRP Values in a General Population 

      Melbye, Hasse; Amundsen, Kristine; Brox, Jan; Eggen, Anne Elise (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-11-17)
      C-reactive protein (CRP) is a much used biomarker for respiratory tract infection; however, the influence of airway infection on the CRP level in the general population has not been well described. The study aimed to evaluate the impact of recent symptoms of airway infection on the CRP level and how the predictive power of other known CRP predictors is influenced by taking respiratory symptoms ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03)
      Background - Most patients presenting with acute exacerbations of chronic obstructive pulmonary disease (AECOPD) in primary care are prescribed antibiotics, but these may not be beneficial, and they can cause side effects and increase the risk of subsequent resistant infections. Point-of-care tests (POCTs) could safely reduce inappropriate antibiotic prescribing and antimicrobial resistance.<p> ...

      Background - Several changes have led to general practitioners (GPs) working in a more differentiated setting today and being supported by other health professions. As practice changes, primary care specific continuing medical education (CME) may also need to adapt. By comparing different primary care specific CME approaches for GPs across Europe, we aim at identifying challenges and opportunities ...

    • Convolutional Neural Network for Breathing Phase Detection in Lung Sounds 

      Jacome, Cristina; Ravn, Johan; Holsbø, Einar; Aviles-Solis, Juan Carlos; Melbye, Hasse; Ailo Bongo, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-15)
      We applied deep learning to create an algorithm for breathing phase detection in lung sound recordings, and we compared the breathing phases detected by the algorithm and manually annotated by two experienced lung sound researchers. Our algorithm uses a convolutional neural network with spectrograms as the features, removing the need to specify features explicitly. We trained and evaluated the ...
    • Cross-sectional associations between prevalent vertebral fracture and pulmonary function. The sixth Tromso Study 

      Morseth, Bente; Melbye, Hasse; Waterloo, Svanhild Haugnes; Thomassen, Marte Renate; Risberg, Marijke Jongsma; Emaus, Nina (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Persons with vertebral fracture may have reduced pulmonary function, but this association has not been much studied. The aim of this cross-sectional study was therefore to examine the relationship between vertebral fracture and pulmonary function in a general, elderly population. Vertebral morphometry was used for vertebral fracture assessment in 2132 elderly men (n = 892) and women (n = 1240) aged ...
