Little is known about the effects of sleep disturbance (SD) on clinical outcomes after spine surgery. ⋯ One-quarter of spine surgery patients reported preoperative SD of at least moderate severity. Poor preoperative sleep quality and ongoing postoperative sleep disturbance were significantly associated with worse scores on several HRQoL measures. These results highlight the importance of addressing patients' sleep disturbance both before and after surgery.
