This study explores the effects of minimizing Emergency Department (ED) bypass on individual hospital's ED census, ambulance transports, and admissions. Five hospitals in a geographic area collected data over 3 weeks. The first and third week represented controls, whereas the second week hospitals minimized their usage of bypass. ⋯ There were several statistical shifts in the proportion of ambulance runs and admissions seen by individual hospitals. Clinically, these shifts in patients were minor and within ED capacity. Hospitals in a given geographic area may successfully reduce the number of hours on bypass with possible minor shifting in the number of ambulance runs and admissions that are within ED capacity.

Multicenter Study
Can urine dipstick be used as a surrogate for serum creatinine in emergency department patients who undergo contrast studies?
Contrast-induced nephropathy (CIN) is a complication associated with contrasted computed tomography (CT). Elevated creatinine (Cr) is often used to screen for CIN. This study evaluates dipstick urinalysis (Udip) detection of Cr > 1.5 mg/dL. ⋯ Thirty-five patient visits (among 26 patients) had negative urine dip and Cr > 1.5 mg/dL, but each reported at least one of the following at triage: prior renal disease, hypertension, diabetes, congestive heart failure, or age > 60 years. Udip is a sensitive screening test, but alone is not accurate enough to predict patients at potential risk for CIN (Cr > 1.5 mg/dL). However, combining Udip results with risk factor screening may allow a rapid method for predicting which patients may safely undergo contrast CT scanning in the ED, but this needs prospective evaluation.
