Purpose
• Monthly educational opportunity for providers within the Central Region
• Focus– Performance improvement, actual case review– Literature review– Discuss practice management guidelines
![Page 3: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/3.jpg)
Performance Improvement
• Review performance and safety of EMS system– Expected or unexpected mortality?– Opportunity for improvement?
• Now the actual work begins…– System or individual?– Preventable or not?– Is the issue open or closed?
![Page 4: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/4.jpg)
Corrective Action
• Develop or revise a guideline• Targeted education• Enhance resources, communication• Counseling• Change in provider privileges or credentials• External review (region, trauma center, etc.)
![Page 5: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/5.jpg)
Results
• Demonstrate that a corrective action has the desired effect by continued evaluation
• Continuous use of your new PIPS process is more important than “loop closure”

MVC
• CT findings and hemoglobin value of 4.8 prompt referral to Level I trauma center
• Intubated, chest tube, pelvic binder placed• Arrival 7 hours after injury
Excessive time to definitive care?What was the indication for intubation?
Does the pelvic injury necessitate pelvic binder?

MVC
• Ventilator-associated pneumonia• Transfusion, nutritional supplementation• No operation required for pelvis• Prolonged ICU admission, LTAC transfer with
significant disability
![Page 19: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/19.jpg)
Young and Burgess Classification
• Vector of force, severity, ligamentous disruption, rotational instability
• Grade I-III• Anterior-posterior• Lateral• Vertical shear
![Page 20: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/20.jpg)
Summary Points
• Early referral for extremes of age• Pelvic binder when loss of rotational stability,
most often APC, closes down pelvic volume• If you take the time to scan… do it right– Include entire torso– Use IV contrast– Renal function rarely a consideration
![Page 21: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/21.jpg)

critical care?

Summary Points
• Diagnostic dilemma: Problem with A or B?• Pre-hospital care was good• Large air leaks require urgent operative
intervention—delay to OR• Pulmonary contusions, when present soon
after injury, associated with high mortality
![Page 35: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/35.jpg)
Pulmonary Contusion
• Parenchymal hemorrhage, inflammatory destruction of the alveolar-capillary membrane
• Historical mortality rates 40%• Mechanical ventilation, antibiotics, invasive
monitoring MAY improve outcomes (6.5%)• Supportive care
![Page 36: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/36.jpg)
Crash and occupant predictors of pulmonary contusion
O’Conner JV, Scalea TM Crash Injury Research and Engineering Network (CIREN)
J Trauma 2009 Apr 66(4):1091—5
• 2,184 crash occupants• Strong association with higher delta V (severity)• Risk greatly increased with near-side lateral impact, suggests
occupant proximity to force most important• Not an independent marker for mortality
![Page 37: Missouri EMS Central Region October 2011 Webinar Jeffrey Coughenour, MD, FACS Assistant Professor of Surgery Medical Director, Missouri EMS Central Region.](https://reader035.fdocuments.in/reader035/viewer/2022062803/56649c985503460f94953e72/html5/thumbnails/37.jpg)
Pulmonary contusion: An update on recent advances in clinical management
Cohn SM, DuBose JJWorld J Surg 2010 Aug 34(8):1959—70
• 47% present on admission• 92% present by 24 hours• 24-48 hour progression• Resolution after 4-6 days• Delay prompts investigation
for infiltrate, fluid overload, TRALI, aspiration
