I recently switched off of per visit to hourly after lots of fighting for it. I am so much happier and feel I finally compensated for my time. As,a per diem they would send me all over the place and very little continuity of care. So I would do a solid chart review and spend time with the pt, often referring back to my computer to verify order which slows you down, then have to finish charting at home. I was not compensated for researching pt prior to visit, travel time, documentation time, calls from care givers or doctors or whatever later that night or next day. It's a lot of little bits of time that all add up to an average of 2hrs per visit which translated to very low pay. You need to ask a lot of questions prior, ask about territory size, continuity of pts, can you bill hourly for extra work later or next day etc. Good luck
