Emergency Ultrasound
James Rippey & the Sonoboys
An audit of 1750
sequential DDU ED Cases
7 months
Background
• The Vision
– Ultrasound is user dependent
– DDU vs CCPU
– The Roster
• Why the audit?
– Financial accountability
– Hospital Politics
Background• Method
– Only DDU scans counted
– Relied on the Sonoboys to enter the cases

The Future
• Who knows?
• What do you want as a potential patient?
• Conveyor belt medicine
• Clinical Emergency Sonologist should be part of that conveyor belt
