Summary
This study identified surgical errors during joint replacements using time-action and error analysis. Improvements include better instruments, experienced staff, and organized instrument tables for enhanced patient outcomes.
Area of Science:
- Orthopedic Surgery
- Surgical Safety
- Biomedical Engineering
Background:
- Joint replacement surgeries are complex procedures with potential for errors.
- Identifying and mitigating these errors is crucial for improving patient outcomes and surgical efficiency.
Purpose of the Study:
- To identify errors and error pathways during joint replacement surgeries.
- To propose actionable improvements based on the analysis of surgical procedures.
Main Methods:
- Adapted a time-action and error analysis method for surgical evaluation.
- Identified, quantified, and analyzed error paths and their impact.
- Evaluated five knee and 11 elbow replacements performed by experienced surgeons.
Main Results:
- Inadequate instruments were the primary error source in elbow replacements.
- Inexperienced nursing staff unfamiliar with guiding instruments led to errors in knee replacements.
- Significant variations in procedure duration were observed, with cementing and nursing support causing major delays.
Conclusions:
- Joint replacement procedures benefit from improved fixation techniques.
- Enhancing nursing staff experience and optimizing instrument table organization are key to reducing errors and delays.
- The time-action and error analysis method effectively identified critical areas for surgical improvement.
