The Norwegian Registry for Spine Surgery (NORspine) provides data from demographics, lifestyle, comorbidity, and patient-reported outcome measures after spine surgery. Lumbar Spinal Stenosis (LSS) is the most common cause for spine surgery in the elderly . The indication for surgery is relative and surgical treatment provides benefit over non-operative care in appropriately selected patients. Advanced age and comorbidity rates are known risk factors of this patient group. Patients at high risk of failure may be identified and surgery avoided where results are poor. Effective and individual risk assessments are important to reduce the number of failed operations.
A report from NORspine shows significant differences in patient-reported outcome after spine surgery between Norwegian hospitals, but also in risk factors among the patients. Adjusted for these risk factors, the differences in outcome vanish. Hence, the diversity in outcome is probably not due differences in patient selection.
A risk calculator can predict the probability for three different possible outcomes: success, failure, or worsening. It will help the patient and the surgeon to understand the individual risk for success or failure. NORspine offers an opportunity to develop a risk calculator for clinical decision support.
The aim of this study is to reduce the number of failed operations by facilitate the shared decision-making process with a risk calculator by defining an individual risk profile.
