Abstract
Purpose
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.
Methods and results
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.
Conclusion
Indications for surgical treatment of lumbar disc herniation appear to be similar in public and private hospitals. Patients operated in private clinics seem to be handled more effectively. They were younger, healthier and had more socioeconomic and lifestyle attributes, known to be predictors more favorable outcomes after surgery.
