BACKGROUND CONTEXT: Poorer outcomes of treatment are reported in patients with spinal disorders who receive workers compensation. The reason for their suboptimal outcomes is unclear. No study has examined the relationship between workers compensation and the Short Form Health Survey (SF-36) health status of patients with spinal disorders. PURPOSE: To compare the self-perceived health status of spinal disorder patients receiving workers compensation with those not receiving workers compensation. STUDY DESIGN/ SETTING: A cross-sectional study on 18,389 patients who were evaluated in the 28 centers comprising the National Spine Network. PATIENT SAMPLE: The study data were derived from patients when first evaluated for back or neck pain between January 1998 and April 2000. OUTCOME MEASURES: The outcome measures used were the eight individual and two component scores of the SF-36. METHODS: All first-visit patients enrolled in the National Spine Network from January 1998 to April 2000 were reviewed. Eight individual scores and two component scores of the SF-36 were compared. RESULTS: Of the 18,389 patients, 1,535 (8%) were receiving workers compensation. Bivariate analyses showed all eight individual scores, and two summary scores of the SF-36 were significantly lower (p<.0001) in patients receiving workers compensation. After controlling for confounding covariates, workers compensation status was a significant predictor of lower SF-36 scores for General Health (p<.0001), Physical Functioning (p<.0001), Role Physical (p<.01), Social Functioning (p<.05), and Mental Health (p<.05). CONCLUSIONS: Workers compensation status is associated with poorer physical and mental health of patients with spinal disorders. Because the workers compensation group is younger, has a shorter duration of symptoms, and fewer comorbid medical problems, the lower SF-36 scores most likely reflect psychological factors and not ill health per se. The lower SF-36 scores may also reflect premorbid personality differences in the workers compensation patients, compared with those not receiving workers compensation. SF-36 is a validated tool that can be used to objectively identify the patient at risk for delayed recovery. Future treatment protocols should pay special attention to improve the health-related quality of life, especially general health and physical functioning of spinal patients receiving workers compensation.
