Do Patient Expectations of Spinal Surgery Relate to Functional Outcome?

Abstract
Dict improvements in functional outcome scores after surgery. We prospectively enrolled 155 consecutive surgical patients with greater than 90% followup. Patients' expectations were evaluated preoperatively along with SF-36 and Oswestry disability questionnaires. Postoperatively (6 months for decompression; 1 year for fusions), we quantified patient-derived satisfaction regarding whether expectations were met and by patient-derived functional outcome scores. In patients undergoing decompression, gender, SF-36 general health domain, and SF-36 physical component score predicted patients with high expectations for surgery. Patients with high expectations also reported greater postoperative improvements in SF-36 role physical domain scores after surgery. Expectations for surgery were met in 81% of patients. In a subset of patients (21 of 143), expectations were not met. These patients reported lower mean preoperative SF-36 general health, vitality, and mean mental component scores. Level of Evidence: Level I, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence....
