Background:
Morbidity and Mortality meetings (M&Ms) are a fundamental element of surgical practice. However, there has been little investigation into best practices, to maximise education and improvement outcomes.
Objective:
Create a new, evidence-based M&M methodology, that facilitates standardised analysis of errors in a non-judgemental fashion, and highlights areas for improvement.
Methods:
A Quality Improvement (QI) methodology was used. This project encompassed a literature review and two sequential QI cycles. A literature review and initial survey highlighted best practice and identified areas for improvement. From this information, a new standardised format was created, which centred around a new modified Fishbone framework, incorporating the London Protocol methodology. The project then sequentially tested new formats, with feedback collected for every new format.
Results:
The literature review and surveys guided improvement of the M&M. The need for standardisation was highlighted. The new PowerPoint template and modified Fishbone ensured presentations and analysis were consistent and systematic. Participants reported that M&Ms were more engaging, interactive and structured, ensuring improved discussion of errors. The modified Fishbone framework reinforced a blame-free, system-focused analysis.
Conclusion:
M&Ms are a critical aspect of patient safety. This project utilised simple QI tools to encourage collaborative reflection, learning and improvement.
Insights
This study developed an evidence-based Morbidity and Mortality (M&M) meeting methodology using Quality Improvement (QI) tools. The new approach standardizes error analysis, fostering a blame-free environment for enhanced patient safety and learning.
Area of Science:
- Surgical Education
- Patient Safety
- Quality Improvement Science
Background:
- Morbidity and Mortality (M&M) meetings are crucial in surgical practice.
- Existing M&M practices lack standardized best practices for maximizing educational and improvement outcomes.
Approach:
- Employed a Quality Improvement (QI) methodology involving literature review and two sequential QI cycles.
- Developed a novel, standardized M&M format incorporating a modified Fishbone framework and the London Protocol.
- Iteratively tested and refined the new M&M format based on participant feedback.
Key Points:
- Literature review and surveys identified key areas for M&M improvement and best practices.
- A standardized PowerPoint template and modified Fishbone framework ensure consistent, systematic M&M presentations and analysis.
- Participants found the new M&M format more engaging, interactive, and structured, leading to improved error discussion.
Conclusions:
- The modified Fishbone framework promotes a blame-free, system-focused analysis of errors.
- This QI project successfully enhanced M&M meetings through collaborative reflection, learning, and improvement.
- The developed methodology is a critical tool for advancing patient safety in surgical settings.
