in the ED led to change in management in 39 (31%) patients. Ten (8%) patients underwent surgery or drainage, and 16 (13%) patients underwent ERCP. Of patients who received an intervention, the mean age was 62 (SD 16) compared with those with no intervention, mean age 52 (SD 17). This difference was significant for both ERCP (p¼0.06) and surgery/drainage (p¼0.04). There was no significant difference found in the lab values, initial vital signs and sex between the two groups.Conclusions: In clinical practice at this institution and others, CT is widely utilized as the first line imaging modality for assessment of many of the causes of abdominal pain, including acute pancreatitis, despite past data suggesting it does not alter management in most cases. Our study suggests that a larger proportion of patients went on to intervention (21%) based on CT findings than has previously been reported. Of the demographic, initial vital signs, and lab values analyzed, the only significant difference found was that the patients who went on to receive interventions were significantly older.Study Objectives: Hyperkalemia (HK) is a common emergency department (ED) presentation. Although electrocardiogram (ECG) changes are generally believed to identify patients at high risk of adverse cardiovascular events, they may not reliably predict outcomes or correlate with degree of HK. In addition, it is commonly thought that patients who present to the ED with HK for the first
