Sammendrag
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.

Methods Data from the national spine registers in Sweden, Denmark and Norway during 2011–2013 were pooled, and 9965 individuals, aged 18–65 years, of which 6468 had one-year follow-up data, were included in the study. Both absolute and case-mix-adjusted comparisons of the primary outcome Oswestry Disability Index (ODI) and the secondary outcomes EQ-5D-3L, and Numerical Rating Scale (NRS) for leg and back pain were performed. Case-mix adjustment was done for baseline age, sex, BMI, smoking, co-morbidity, duration of leg pain and preoperative value of the dependent variable.

Results Mean improvement in the outcome variables exceeded previously described minimal clinical important change in all countries. Mean (95% CI) fnal scores of ODI were 18 (17–18), 19 (18–20) and 15 (15–16) in Sweden, Denmark and Norway, respectively. Corresponding results of EQ-5D-3L were 0.74 (0.73–0.75), 0.73 (0.72–0.75) and 0.75 (0.74–0.76). Results of NRS leg and back pain behaved similarly. Case-mix adjustment did not alter the fndings substantially.

Conclusion We found no clear association between incidence of surgery for lumbar disc herniation and preoperative patient characteristics as well as outcome, and the diferences between the countries were lower than the minimal clinical important diference in all outcomes.
