We do about the same thing. Schedule the long infusions and blood in the am and the antibiotics in the pm.We set up one area just for injections,aranesp,neupogen,neulasta and such quick in and outs. We had the same problem of them all showing up whenever, in the old world with 6 chairs this was how it was done but now in the new world with 30 chairs we have to schedule appts and as iluvivt said we nicely remind them that they are early and we might be able to work them in..Sometimes someone might have another appt in town and we try to accomadate them. Our receptionist tells them up front that they are early but I will let the nurses know you are here. They all wait in the lobby. Even if they came for a blood draw and tx based on the results we send them to the lobby for the wait time.
