APD regimes?

[talaxandra]

Greetings all :)

We recently admitted a patient who's usually managed by a different hospital (he'd come in for an elective surgery with us) and I was struck by the difference between hospital regimens:

Hospital X's routine HomeChoice program is 2L exchanges, 15L total volume and a 10/24 program, giving the patient six or seven (depending on whether or not there's a last/day time dwell) exchanges and an average dwell time of an hour.

Hospital Y's routine HomeChoice program is 1.8L exchanges, 10L total volume and a 10/24 program, giving the patient four or five (depending on whether or not there's a last/day time dwell) exchanges and an average dwell time of two hours.

I asked our PD educator about the difference and she said "Oh, that's the way they do it" which I didn't think relly helped. SO, those of you who work with APD - what regime do you follow and (if you know) why?
