Patient expectations influence post-treatment outcomes, both surgical and non-surgical. Existing studies evaluate the technical aspects of interventions and functional outcomes but fail to take into account patient expectations. This retrospective analysis of prospectively collected multi-center data aims to explore the relationship between pre-operative expectations and post-operative outcomes and satisfaction in lumbar and cervical spine surgery. The authors hypothesized that expectations dramatically affect spine patient satisfaction independent of functional outcomes. Patient data from lumbar and cervical spine patients collected prospectively using a patient health survey system was analyzed. The study included patients who underwent operative intervention (decompression with or without fusion) with at least a 3-month period of follow-up. Pre-operative expectations were measured using the MODEMS expectation survey. Post-operative satisfaction and fulfillment of expectations were measured using the MODEMS satisfaction survey. Post-operative functional outcomes were measured using the ODI and SF-36. Multi-variate ordinal logistic regression modeling was used to examine predictors of post-operative satisfaction. Multi-variate linear regression modeling was used to examine predictors of functional outcomes.Purpose
