Using prospective outcomes data to improve morbidity and mortality conferences
1Department of Surgery, Dartmouth Medical School, Hanover, New Hampshire, USA
Surgical morbidity and mortality (M&M) conferences can be improved by incorporating outcomes registry data. This approach enhances resident education and identifies opportunities for improving surgical quality and patient outcomes.
Area of Science:
- Surgical Education
- Quality Improvement in Healthcare
- Patient Outcomes Research
Background:
- Traditional surgical morbidity and mortality (M&M) conferences often focus on rare events and treat complications in isolation.
- This limits their effectiveness in teaching residents to understand and improve patient outcomes.
- An outcomes registry was developed for general surgery to capture prospective data on patient outcomes and adverse events.
Purpose of the Study:
- To integrate prospective data from a general surgery outcomes registry into morbidity and mortality (M&M) conferences.
- To enhance the educational value of M&M conferences for surgical residents and attending physicians.
- To identify opportunities for improving the quality of surgical practice through data-driven review.
Main Methods:
- An outcomes registry prospectively collects data on approximately 2000 general surgery procedures annually.
- Adverse events within 30 days of surgery are categorized by severity (Grades I-IV) by clinical nurse coordinators.
- Data on caseloads and adverse events are provided to senior residents for presentation at M&M conferences, contextualized by departmental and external benchmark data.
Main Results:
- Incorporating outcomes registry data into M&M conferences is feasible and practical.
- This approach allows for the presentation of individual cases within the context of broader departmental experience and trends.
- It facilitates the exploration of relationships between practice changes and patient outcomes.
Conclusions:
- Integrating prospective outcome data into M&M conferences enhances resident and attending physician education.
- This data-driven approach provides significant opportunities for improving surgical quality and patient safety.
- The methodology supports a shift from reviewing isolated complications to understanding recurrent events within care processes.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care evaluation by...
