Patient safety in trauma poses unique challenges given the acuity of the patients and the need for rapid assessment in delivering life-saving care. This study analyzed more than 2500 complications discussed at morbidity and mortality (M&M) conferences to characterize their preventability and clinical relevance. Investigators discovered that the complications ripe for quality improvement initiatives included unintended extubations, surgical technical failures, missed injuries, and intravascular catheter-related complications. An invited critique [see link below] reflects on the study's findings and points out the challenges in reporting performance data without needed standardization. A past AHRQ WebM&M commentary discussed the systematic assessment of trauma patients in the context of a missed patient injury.
