Application of Multidimensional Quality Management Tools in the Management of Medical Adverse Events.

Purpose: This study aims to investigate the impact of multidimensional quality management tools in establishing a medical adverse event management system, with the aim of continuously improving medical quality and safety while ensuring patient well-being. Methods: This study introduces risk management theories, such as the "Gray Rhino Theory", and employs quality management tools like the Plan-Do-Check-Act (PDCA) cycle, Quality Control Circle (QCC), and Root Cause Analysis (RCA), to provide relevant quality management education and training to employees. This approach facilitates the establishment of a medical adverse event management system that encourages reporting and fosters a blame-free reporting culture, while simultaneously implementing quality management across the entire process. The regular utilization of the QCC facilitates ongoing quality improvement. Furthermore, for sentinel events and patient harm incidents with educational values, the study employs the Incident Decision Tree (IDT) to determine appropriate actions. Additionally, the hospital initiates RCA for system-wide improvements, focusing on areas such as management, institutional processes, and environmental aspects. Moreover, an internal medical quality improvement case competition is organized, with outstanding cases being selected to participate in the multidimensional quality management competition organized by the National Quality Management Alliance. Results: The study reveals a significant improvement in employees' awareness of adverse events, the percentage of employees reporting adverse events increased significantly from 39.15% in 2019 to 49.77% in 2022, P=0.002. Furthermore, the adverse event reporting rate has risen significantly from 2.78% (2019) to 5.96% (2022), P=0.002. Additionally, each department has been able to utilize QCC or RCA tools for quality improvement, thereby further reinforcing the development of a patient safety culture. Conclusion: Multidimensional quality management tools play a crucial role in establishing a hospital's adverse event management system, promoting continuous improvement in medical quality, ensuring patient safety, and effectively implementing a culture of patient safety.
