• Patient Assessment Committee

    The AAST Patient Assessment Committee is focused on developing systems to measure disease severity and patient outcomes for research and quality improvement in acute care surgery. 

    One of our largest projects in the past five years has been to define the scope and burden of emergency general surgery diseases (EGS) in the United States and to create an anatomic grading scale for EGS diseases that is intuitive and that can be used for both clinical and research purposes.  Anatomic severity of illness scales have been described for 20 of the most common EGS conditions, and many of these scales have been externally validated.  In addition, we have created EGS guideline summaries and have helped create a framework for EGS risk stratification.

    Our committee has also created a draft of an EGS Optimal Resources Document, which is similar to the trauma optimal resources document.  We have been working with a group led by the American College of Surgeons David Hoyt, Raul Coimbra, and multiple stakeholders from other organizations to edit the document as well as determining the feasibility of a verification/certification process for EGS.  This also includes an EGS registry/data standards project; these elements have been identified and the data dictionary is being created with the ACS, to align language with similar quality data standards, such as NSQIP and TQIP.

    Some of our new and ongoing projects include a multi-centered prospective clinical trial of cholecystitis; multiple collaborative efforts with groups interested in geriatric trauma, EGS triage and transfer guidelines, and participation in the Center for National Trauma Research Scientific Advisory Committee.  This year, we completed a multi-institutional study of necrotizing soft tissue infection, and helped update the AAST Anatomic Injury Score for solid organ injuries.  Finally, we just completed a survey of comfort level among acute care sureons of vascular trauma and non-trauma emergencies that will be forthcoming this year.  Our group also welcomes any suggestions for projects and papers.

    In summary, I would like to thank all the hard-working members of the Patient Assessment Committee, the Board of Managers, and Ms. Sharon Gautschy, and Ms. Brea Sanders for their invaluable support.  Thank you for the opportunity to highlight our work!
