Abstract
Background
Abdominal Pain is the most common cause of visits to US Emergency Departments (EDs) and the causes range from urgent to non-urgent diagnoses. Distinguishing urgent versus non-urgent causes of abdominal pain is done through the use of clinical exam, lab studies and diagnostic imaging such as CT scans. There are no validated clinical decision rules to assist physicians in discriminating urgent from non-urgent causes of abdominal pain or which patient needs a CT scan. There is controversy regarding the use of CT scans for patients with abdominal pain due to the increased cost, radiation exposure and length of stay.
Objective
The objective of this study is to compare the demographics, pain score and CT utilization for patients with urgent versus non-urgent causes of abdominal pain.
Methods
At an academic ED, a convenience sample of patients with abdominal pain was prospectively enrolled by research assistants during the ED visit. Research assistants abstracted treatment information from the electronic medical record for the ED and hospitalization if applicable. Finally, enrollees were telephoned 2 weeks after the index ED visit to ascertain symptom resolution and treatment outcomes. Following establishment of final diagnosis, patients were classified as having an urgent or non-urgent diagnosis based upon published peer-reviewed criteria. Risk differences in pain severity, CT scan utilization and demographics were compared to urgency of diagnosis and a paired t-test was used to estimate differences in initial clinical characteristics.
Results
In a model of 725 patients, 144 had urgent diagnoses and 561 had non-urgent diagnoses. There was no distinction in insurance type, income level, mean age or pain score in the two groups. Ct scan utilization was higher in patients with urgent diagnoses (42.4% versus 16.4%.)
Conclusion
20.4% of patients had an urgent diagnosis for the abdominal pain. There was no difference in the pain score for patients with urgent versus non-urgent diagnosis. While work-up bias is a potential limitation, CT scan utilization was higher in patients with an urgent diagnosis suggesting appropriate clinical judgement. Future studies will need to look at ways to target the testing to more high-risk patients who present with undifferentiated abdominal pain.
