The aims of this study were to determine the rates of surgical complications, reoperations, and readmissions following herniated lumbar disc surgery, and to investigate the impact of sociodemographic factors and comorbidity on the rate of such unfavourable events. This was a longitudinal observation study. Data from herniated lumbar disc operations were retrieved from a large medical database using a combination of procedure and diagnosis codes from all public hospitals in Norway from 1999 to 2013. The impact of age, gender, geographical affiliation, education, civil status, income, and comorbidity on unfavourable events were analyzed by logistic regression.Aims
Patients and Methods
Measurement inconsistency across clinical trials is tackled by the development of a core outcome measurement set. Four core outcome domains were recommended for clinical trials in patients with non-specific LBP (nsLBP): physical functioning, pain intensity, health-related quality of life (HRQoL), and number of deaths. This study aimed to reach consensus on core instruments to measure the first three domains. The Steering Committee overseeing this project selected 17 potential core instruments for physical functioning, three for pain intensity, and five for HRQoL. Evidence on their measurement properties in nsLBP was synthesized in three systematic reviews using COSMIN methodology. Researchers, clinicians, and patients (n = 208) were invited in a Delphi survey to seek consensus on which instruments to endorse as core. Consensus was Background & purpose
Methods & Results
To investigate sociodemographic and clinical characteristics in patients operated for lumbar disc herniation in public and private hospitals, and evaluate whether selection for surgical treatment were different across the two settings. A cross-sectional multicenter study of patients who underwent a total of 5308 elective surgeries for lumbar disc herniation at 41 hospitals. Data were included in the Norwegian Registry for Spine Surgery (NORspine). Of 5308 elective surgical procedures, 3628 were performed at 31 public hospitals and 1680 at 10 private clinics. Patients in the private clinics were slightly younger, more likely to be man, have higher level of education, and more likely to be employed. The proportions of disability and retirement pension were more than double in public as compared to private hospitals. Patients operated in public hospitals were older, had more obesity and co-morbidity, lower educational level, longer duration of symptoms, and sick leave and were less likely to return to work. Patients operated in public hospitals reported more disability and pain, poorer HRQol and general health status than those operated in private clinics. The differences were consistent but small and could not be attributed to less strict indications for surgical treatment in private clinics.Purpose
Methods and results
To compare the contribution of physical, psychological and social indicators to predicting disability after one year between consulters with low back pain (LBP) of less than 3 months duration and more than 3 months duration. Data from two large prospective cohort studies of consecutive patients consulting with LBP in general practices were merged, with disability measured by the Roland Morris Disability Questionnaire (RMDQ). There were complete data for 258 cases with acute/subacute LBP and 668 cases with chronic LBP at 12 months follow-up. Univariate and adjusted multivariate regression analyses of various potential prognostic indicators for disability at 12 months were carried out.Purpose
