title: Abdominal pain: a survey of clinically important outcomes for future research.
abstract: OBJECTIVE
  We aimed to use the consensus opinion of a group of expert emergency physicians to derive a set of emergency diagnoses for acute abdominal pain that might be used as clinically significant outcomes for future research.
  
  
  METHODS
  We conducted a cross-sectional survey of a convenience sample of emergency physicians with expertise in abdominal pain. These experts were authors of textbook chapters, peer-reviewed original research with a focus on abdominal pain or widely published clinical guidelines. Respondents were asked to categorize 50 possible diagnoses of acute abdominal pain into 1 of 3 categories: 1) unacceptable not to diagnose on the first emergency department (ED) visit; 2) although optimal to diagnose on first visit, failure to diagnose would not be expected to have serious adverse consequences provided the patient had follow-up within the next 2-7 days; 3) if not diagnosed during the first visit, unlikely to cause long-term risk to the patient provided the patient had follow-up within the next 1-2 months. Standard descriptive statistical analysis was used to summarize survey data.
  
  
  RESULTS
  Thirty emergency physicians completed the survey. Of 50 total diagnoses, 16 were categorized as "unacceptable not to diagnose in the ED" with greater than 85% agreement, and 12 were categorized as "acceptable not to diagnose in the ED" with greater than 85% agreement.
  
  
  CONCLUSIONS
  Our study identifies a set of abdominal pain conditions considered by expert emergency physicians to be clinically important to diagnose during the initial ED visit. These diseases may be used as "clinically significant" outcomes for future research on abdominal pain.
