The empiric treatment may vary from hospital to hospital based on local resistance rates. For example, we don't use a lot of amoxicillin because our local resistance is approaching 20%, instead we use cephalosporins and bactrim.
In peds, i haven't seen quinolones used in pre-pubertal kids without ID's giving their approval in the setting of very resistant bacteria or patient medical allergies.
The quinolone problem (arthropathy, joint cartilage problems, etc) has only been studied in beagle puppies (try to get that pediatric study past the IRB!) which is why ID folks will give the OK for special situations.
