Summary
Predictors of spinal surgery outcomes vary by measurement. Medical and psychosocial factors significantly predict outcomes using a multidimensional core measure index, supporting its clinical use.
Area of Science:
- Orthopedics
- Spinal Surgery
- Health Outcomes Research
Background:
- Surgical outcome prediction often depends on the chosen success metric.
- A multidimensional core outcome measure index (including pain, function, well-being, disability) was developed.
Purpose of the Study:
- To identify predictors of surgical outcomes using the novel multidimensional core measures.
- To analyze the predictive power of medical and psychosocial factors on different outcome domains.
Main Methods:
- 163 spinal surgery patients completed pre- and post-operative questionnaires.
- Data collected included demographics, medical history, Fear-Avoidance Beliefs Questionnaire (FABQ), Zung Self-Rated Depression, and core outcome measures.
- Multiple regression analyses were performed to identify predictors for individual domains and the combined index.
Main Results:
- A combination of baseline symptoms, medical variables, and psychosocial factors (FABQ, Zung depression) explained 34% of the variance in the core measures index.
- Medical variables better predicted pain and symptom-specific well-being.
- Psychosocial factors better predicted function, general well-being, and disability.
Conclusions:
- The multidimensional core outcome measures are sensitive to change and predictable by established medical and psychosocial factors.
- These findings support the use of the core-set in registry systems, quality management, and clinical trials for spinal surgery.
- Both medical and psychosocial factors play crucial, distinct roles in predicting different aspects of surgical outcomes.
