This study intends to establish a multidisciplinary collaborative ERAS clinical pathway of cervical posterior surgery,and to verify its effectiveness, safety and value in health economics.

Enhanced recovery after surgery (ERAS) is a new model of deep cooperation between surgery，rehabilitation medicine, anesthesiology, nursing and other disciplines in recent years, which enables patients to start rehabilitation training as soon as possible after surgery and improves the comprehensive effect of surgery. Posterior cervical surgery is traumatic, and it is significant to enhance postoperative rehabilitation to improve the overall efficacy of patients. Currently, there are no clear guidelines supporting the clinical effectiveness of ERAS in reducing complications, reducing costs, and enhancing recovery after posterior cervical surgery. Therefore, this study aims to establish a multidisciplinary ERAS model for posterior cervical surgery in Peking University Third Hospital and verify its clinical effectiveness. This is a multi-center, multidisciplinary prospective cohort study,in which the orthopedics department was combined with the anesthesiology department, rehabilitation department, nutrition department, operating room and nursing team to establish the ERAS clinical pathways for posterior cervical spine surgery. Clinical pathways include surgical procedure optimization, rehabilitation procedure optimization, anesthesia and nursing procedure optimization. As it is optimized and promoted,the ERAS clinical pathways will improve the curative effect and prognosis of posterior cervical surgery, so that more patients with cervical spondylosis will benefit.
