    • Accuracy and agreement of national spine register data for 474 patients compared to corresponding electronic patient records 

      Alhaug, Ole Kristian; Kaur, Simran; Dolatowski, Filip C; Småstuen, Milada Cvancarova; Solberg, Tore; Lønne, Greger (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-06)
      Purpose - Data quality is essential for all types of research, including health registers. However, data quality is rarely reported. We aimed to assess the accuracy of data in a national spine register (NORspine) and its agreement with corresponding data in electronic patient records (EPR).<p> <p>Methods - We compared data in NORspine registry against data in (EPR) for 474 patients operated for ...

    • Characteristics and outcomes of patients who did not respond to a national spine surgery registry 

      Kaur, Simran; Alhaug, Ole Kristian; Dolatowski, Filip Celestyn; Solberg, Tore; Lønne, Greger (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-04)
      Background Loss to follow-up may bias outcome assessments in medical registries. This cohort study aimed to analyze and compare patients who failed to respond with those that responded to the Norwegian Registry for Spine Surgery (NORspine).<p> <p>Methods We analyzed a cohort of 474 consecutive patients operated for lumbar spinal stenosis at four public hospitals in Norway during a two-year period. ...

    • Criteria for failure and worsening after surgery for lumbar disc herniation: a multicenter observational study based on data from the Norwegian Registry for Spine Surgery 

      Werner, David Andreas Thomas; Grotle, Margreth; Gulati, Sasha; Austevoll, Ivar M.; Lønne, Greger; Nygaard, Øystein P.; Solberg, Tore K. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-14)
      PURPOSE: In clinical decision-making, it is crucial to discuss the probability of adverse outcomes with the patient. A large proportion of the outcomes are difficult to classify as either failure or success. Consequently, cutoff values in patient-reported outcome measures (PROMs) for "failure" and "worsening" are likely to be different from those of "non-success". The aim of this study was to identify ...

    • Effectiveness of surgery for sciatica with disc herniation is not substantially affected by differences in surgical incidences among three countries: results from the Danish, Swedish and Norwegian spine registries 

      Lagerbäck, Tobias; Fritzell, Peter; Hägg, Olle; Nordvall, Dennis; Lønne, Greger; Solberg, Tore; Andersen, Mikkel Ø.; Eiskjær, Søren; Gehrchen, Martin; Jacobs, Wilco C.; van Hooff, Miranda L.; Gerdhem, Paul (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-29)
      Purpose Yearly incidence of surgery for symptomatic lumbar disc herniation varies and is 29/100,000 in Sweden, 46/100,000 in Denmark and 58/100,000 in Norway. This variation was used to study whether diferences in surgical incidence were associated with diferences in preoperative patient characteristics as well as patient-reported outcomes.<p> Methods Data from the national spine registers in ...

    • The Norwegian registry for spine surgery (NORspine): cohort profile 

      Mikkelsen, Eirik; Ingebrigtsen, Tor; Thyrhaug, Anette Moltu; Olsen, Lena Ringstad; Nygaard, Øystein Petter; Austevoll, Ivar Magne; Brox, Jens Ivar; Hellum, Christian; Kolstad, Frode; Lønne, Greger; Solberg, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-17)
      Purpose - To review and describe the development, methods and cohort of the lumbosacral part of the Norwegian registry for spine surgery (NORspine).<p> <p>Methods - NORspine was established in 2007. It is government funded, covers all providers and captures consecutive cases undergoing operations for degenerative disorders. Patients’ participation is voluntary and requires informed consent. A set ...
