In the outpatient setting it might take days or a week or more to get an appointment for a formal US, then more time for the radiologist to read it, then more time for the GP to get the results and consider treatment changes then more time to get in touch With the patient. But if I as a physician perform and interpret the ultrasound in real time I can immediately begin appropriate therapy. This is the major benefit of point-of-care US as opposed to conventional US.
