Brief Summary

Unplanned re-operation is one of the common negative indicators reflecting the quality and safety of surgery in the medical industry and has become one of the ten goals for the improvement of national medical quality and safety in China since 2022, while about 40% of unplanned re-operations in Peking University Third Hospital in recent years occur in spine patients of the orthopedics department. This project intends to establish a high-quality and sustainable ambispective disease cohort for spine surgery in Peking University Third Hospital based on the unplanned re-operations that occurred in the Orthopedics Department of Peking University Third Hospital from January 2012 to December 2025. The investigators further summarize and analyze clinical causes and risk factors of re-operations, aiming to explore scientific coping strategies and provide reference for continuous improvement of medical service quality.

Sampling MethodNon-Probability Sample
Study Population

In the retrospective cohort, patients were enrolled from January 2012 to December 2021. They aged from 18 to 80 years with spinal disease who were hospitalized for surgery in the orthopedics department of Peking University Third Hospital and had complete medical records, while diagnosing of fracture, limb arthritis, limb tumor and other non-spinal diseases were excluded. In the prospective cohort, patients were enrolled from January 2023 to December 2025; They aged from 18 to 80 years with spinal disease who were hospitalized for surgery in the orthopedics department of Peking University Third Hospital, while diagnosing of fracture, limb arthritis, limb tumor and other non-spinal diseases were excluded.

You may qualify if:

  • Patients who received orthopedic surgery in Peking University Third Hospital, including spinal degeneration, spinal deformity, spinal tumor, spine fracture reduction and internal fixation
  • Both the initial surgery and unplanned re-operation were completed in the orthopedic department of Peking University Third Hospital
  • The interval between two surgeries is within 30 days
  • Discharged from the orthopedics department of Peking University Third Hospital

You may not qualify if:

  • Re-operation for other systemic diseases unrelated to the initial surgery
  • Re-operation is a clinical procedure that is not a return to the operating room, such as wound debridement and suturing, skull traction, etc. performed in the ward
