Okay, so I work for the other of the "Big Two" companies and as such don't know really anything about working for Davita, much less their starting salary in the Las Vegas area, but I do know about transitioning from a busy intermediate care unit in a hospital to dialysis, because that's what I did about a year ago.
I originally started out as an acute dialysis nurse, which means I did dialysis treatments in several hospitals in our area. The hours were extremely long, there was no routine at all, as in, you could work five hours on Monday and 19 hours on Tuesday, depending on which hospital you were at and how many patients rolled into the ER between Monday and Tuesday. Also, we had to be on call for 2-3 nights a week (6pm-6am, and on the same day when we worked during the day which was ROUGH!) and every other weekend. These conditions are pretty much universal in acute dialysis, with possibly less on call hours if you're lucky. That job was definitely not gonna fly with me, so I recently transitioned into a chronic dialysis unit and am working there full-time now.
I remember very, very well how stressful working on the floor at the hospital was. Admissions rolling up all day long, doctors expecting you to drop everything to round with them and hold their hand (figuratively) and then blaming you and everyone else if anything was not as they liked it, etc., etc. However, I have to tell you that working as an RN in a chronic dialysis unit comes with its own types of stress. If Davita is like my company, you have a group of around twenty patients that you case manage. That means that everything pertaining to their care, their treatments, and their other health issues lands on you and you are expected to address it appropriately. The craziest time is first thing in the morning when the first shift of patients rolls in and you have to assess, pass meds, and chart on your group of patients. Then if you're lucky things slow down a bit during first shift treatments until those patients are done and the next shift starts rolling in. They sometimes come in 2-3 at a time, so you are busy, busy getting everyone settled, assessed, and their meds passed. If you are blessed with awesome dialysis techs like I am, it makes a night and day difference in how your day will go. If you have unskilled/lazy/unhappy techs, God help you, because they do the bulk of the actual dialysis treatments, as there's no way the RN could run treatments on ten people and do all of the paperwork, foot checks, rounding with doctors, etc. that we have to do.
Basically, you would be trading one type of stress for another. Personally, I much prefer chronic dialysis to working on the floor and will never, God willing, work in a hospital as a floor nurse again. I am just hoping that I get quicker and more polished at my dialysis job with time and experience, because there is a lot of responsiblity. And if you don't already know dialysis at all, you will have that learning curve as well, which I fortunately didn't have to worry about since I had done acute dialysis. The techs will ask you what you want them to do when someone's blood pressure suddenly crashes or they develop severe leg cramps, because the RN has to approve and document on any changes in the ordered treatment, and you have to feel confident enough to give them instruction on what to do, such as decrease the patient's UF goal (amount of fluid being removed), decrease the temperature of the dialysate (to cause vasoconstriction and increase BP), or give the patient some fluid back.
I don't know what else to say except good luck. I know what life can be like on the floor!
