Welcome to dialysis! I've been in community dialysis for four months now (first job post-grad). From what I've read on here, it's pretty different from the states! At least in Alberta. It's similar to other units in that there is a charge nurse with a mix of RNs, LPNs, and NAs on the floor.
In my experience, there are usually 4 pods with 5 patients. Each pod has an RN and an LPN. Some units leave it at that and it's very team-oriented in caring for those patients. Some units go a step further and split the pod in two where one nurse has two patients and the other has three and then after that run they switch spots to keep the workload somewhat even. Even in that system, the other nurse is still your buddy but you are basically on your own unless you go ask for help.
On my units (I work PRN/casual on four of them), there are three runs per day (AM, PM, HS).
AM start times are 0715, 0730, and 0745.
PM start times are 1245, 1300, and 1315.
HS start times are 1815, 1830 and 1845.
Depending on the Unit, our shifts either run 0700-1515 and 1500-2315 or 0645-1500 and 1445-2300. Only one unit in my area has nocturnal and it's similar to inpatient/acute dialysis in that they won't let you do it until you are proficient with community/outpatient.
The NAs get there around 6 (I think!) and they prepare the machines. Once the nurses get there, we double check that we have the right supplies, assess our patient, check for medications and labs, program the machine parameters based on the dialysis prescription, put on the patient (needles or CVC) and then do it all again with the next patient. Throughout the run we are right near by and monitoring them at least every half hour as well as doing medications and dressing changes, etc. And we take them off the machines at the end and make sure they are ok to leave.
The NAs really know the machines better than the other staff so I ask them questions often when there are alarms! They also get blankets, keep supplies stocked on the Unit, put patients on and off the bikes and get the machines cleaned and ready in between patients to name a few things.
