EP.FRI.376 Early Routine CT Scans for All Surgical Admissions for Abdominal Pain May Improve Patient Outcomes

Aim Acute abdominal pain remains a diagnostic challenge in the Emergency Department (ED) as pathologies can involve various surgical craft groups. Computed tomography (CT) enables accurate diagnosis of abdominal pathologies. However, with pressures on ED such as the “4 hour rule” established by the Australian NSW Health Emergency Performance Plan, there may be resistance or omission of early CT in ED. We hypothesise that early, routine CT in adult patients presenting with acute abdominal pain requiring hospital admission improves patient outcomes by increasing diagnostic and referral accuracy. This study compares the proportion of correct ED diagnosis of abdominal pain presentations with and without formal imaging reports. Methods Data from 118 patients presenting with abdominal pain are collected prospectively in a regional hospital and analysed. Patient demographics, imaging results, initial ED diagnosis and final discharge diagnosis are further examined. Results Out of the 118 patients who had abdominal pain, 32 patients obtained complete imaging with a radiology report whilst 86 patients either did not have any imaging performed or was referred to a general surgical unit prior to obtaining a formal report. Among the patients who had imaging reported, 78% (n = 25/32) had the correct diagnosis, whilst those without a radiology report had a 52% (n = 45/86) diagnostic accuracy. This demonstrates an improved accuracy of diagnosis or reduced error rate of 26% when a scan report is available (p = 0.01). Conclusion Early, routine CT with formal reporting significantly reduces diagnostic error rates and increases accurate referral. This allows accurate diagnosis and improves patient outcomes.
