What this trial studies

This observational study aims to investigate the causes and risk factors associated with unplanned re-operations in spine surgery patients at Peking University Third Hospital. By establishing a comprehensive cohort of patients who underwent orthopedic surgery from January 2012 to December 2025, the study will analyze clinical data to identify common issues leading to these re-operations. The goal is to develop strategies to improve surgical quality and safety, ultimately reducing the incidence of unplanned surgeries. The findings will contribute to enhancing medical service quality in the orthopedic field.

Who should consider this trial

Good fit: Ideal candidates include patients who have undergone orthopedic spine surgery at Peking University Third Hospital and experienced an unplanned re-operation within 30 days.

Not a fit: Patients requiring re-operation for unrelated systemic diseases or those undergoing non-surgical clinical procedures will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced rates of unplanned re-operations for spine surgery patients.

How similar studies have performed: While the focus on unplanned re-operations in spine surgery is critical, similar studies have shown varying degrees of success in identifying risk factors and improving surgical outcomes.
