Effect of Expanded Dialysis on Patient Reported Symptoms Using LEVIL

Baxter Canada has an expanded hemodialysis (HDx) membrane called the "Theranova", which is capable of removing solutes of higher molecular weight. Although this clearly has biochemical advantages it is not known at this time if the removal of larger middle molecules can have a direct and immediate effect on patients reported symptoms and quality of life. In short, do be people actually feel better? Given the way many QoL measurements fluctuate around the dialysis week, the investigators propose to utilize a dynamic tool. The investigators will be assessing symptom burden using the London Evaluation of Illness "LEVIL" an application based platform where patients self-report their symptoms with at least one hemodialysis treatment. Reports are generated immediately and in real-time, which cannot be accomplished with other symptom management tools. This allows the investigators to track study changes and benchmark observations to previously established baseline values. The investigators are excited to see if there is an imminent effect on how patients feel using the Theranova dialyzer. The study is investigator initiated and the principal investigator has secured modest funding from Baxter to allow support for the core study team and the introduction and maintenance of the LEVIL evaluation platform at other centers. Baxter have also provided some dialyzer support, and will work with individual centers to ensure that there is no consumable increment of cost associated with participation. The study is 60 weeks in length: * LEVIL entries with at least one hemodialysis treatment each week for 60 weeks * Blood sampling at 4 time points for all participants * Implementation of Theranova dialyzer from weeks 5 through 16 and weeks 25 through 48 * Wash out period from weeks 17 through 24 and weeks 49 through 60 * Time to recovery question at the first treatment of weeks 1, 16, 24, and 48 for new participants * 5-D Pruritus scale and Restless Legs Syndrome rating scale at the first treatment of weeks 1, 16, 24, and 48 * Echocardiogram prior to starting hemodialysis and at peak stress at baseline (within the first two weeks), with one treatment between weeks 12 to 16 which will occur mid-week, and with one treatment between weeks 44 to 48 which will occur mid-week (LHSC specific) * CVInsight monitoring at baseline (within the first two weeks), with one treatment between weeks 2 to 16, 20 to 25, and with one treatment between weeks 44 to 48 (LHSC specific) * Non-invasive assessment of cardiovascular risk using the AGE Reader within 1 hour of starting hemodialysis at baseline, with one treatment between weeks 12 to 16, 20 to 24, and with one treatment between weeks 44 to 48 which will occur mid-week (LHSC specific) * Five Time Sit to Stand Test \& 60-Second Chair Test at the second treatment of weeks 1, 16, 24, and 48
