ObjectivesAppendicitis is the most common pediatric surgical emergency. Ultrasonography is recommended as first-line imaging for appendicitis in children; however, this is often followed by more advanced imaging. Our goal was to determine if point-of-care ultrasonography (POCUS) could reduce cost and length-of-stay (LOS) in suspected pediatric appendicitis.MethodsWe performed a chart review of patients presenting to our pediatric emergency department (ED) from August 1, 2017 to June 30, 2019 who had imaging for appendicitis. We compared cost and LOS for patients who received POCUS to those who had magnetic resonance imaging (MRI) as first-line imaging, which is standard at our institution.ResultsWe identified 695 visits of 685 unique patients. Patients who received POCUS (n = 209) had a significantly shorter mean LOS (274 minutes) in the ED compared to patients who did not (317 minutes, P <.001). This was true regardless of the month of their visit. The POCUS group was younger, less likely to have right lower quadrant pain/tenderness, less likely to be admitted, and less likely to have appendicitis than the MRI group. Average appendix imaging cost per patient was lower in the POCUS group at $1308 compared to the MRI group at $1371 (P <.001), although patients who had both POCUS and MRI (n = 102) had the highest average imaging costs ($2010).ConclusionPOCUS can reduce LOS and imaging cost in suspected pediatric appendicitis. Further study is warranted to determine which patients benefit the most from POCUS and whether the results are applicable in other settings.© 2021 American Institute of Ultrasound in Medicine.
