Construction of an Ambispective Cohort for Unplanned Spinal Re-operation

Unplanned re-operation is one of the common negative indicators reflecting the quality and safety of surgery in the medical industry. Possible reasons for a patient's return to the operating room include problems with surgical technique, anesthesia procedures, or infection control. Reducing the rate of unplanned re-operation has become one of the ten goals for the improvement of national medical quality and safety in China since 2022, and has been paid more and more attention by the National Health Commission and hospital managers.

About 40% of the unplanned re-operations in Peking University Third Hospital in recent years occur in spine patients of the orthopedics department, thus lowering the rate of spine unplanned re-operations is of great significance to improve the overall medical quality and safety. Driven by the common needs and joint force of "nation-hospital-department", this project intends to establish a high-quality and sustainable ambispective disease cohort for spine surgery in Peking University Third Hospital based on 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. Furthermore, the investigators intend to construct multiple risk prediction models for spine unplanned re-operation and special disease cohorts. This project will form a synergy in the three aspects of "clinical, scientific research, and management", lower the unplanned re-operation rate of orthopedic spinal surgery, improve medical quality and safety management in Peking University Third Hospital, and promote the in-depth exploration and vigorous development of spine discipline in the scientific fields of perioperative safety and risk assessment.
