Improving outcomes and QoL in patients on long term dialysis: what is the secret?

I was recently a panelist on a discussion at the Indian Society of Hemodialysis Conference on the topic, "Improving outcomes and Quality of Life in patients on long term dialysis".

I have been on dialysis for almost eighteen years now. I lead an almost normal life. I swim every morning. I work full time. I travel regularly. If you asked me what the secret ingredient in this recipe is, I would unhesitatingly say, "hours, hours, hours". The number of hours you spend on the machine, in my mind, is the most important factor.

I could not make that point as forcefully as I would have liked to in the discussion. In any panel discussion, even without Arnab Goswami as the moderator, there is a limited amount of time that each panelist gets to make his or her point. With Arnab, you have a second or two before he would interject and then make your point for you even if it is not really your point!

But, I digress.

There are two things dialysis removes - fluid and toxins. You can use a better dialyzer to remove toxins in a better manner. However, for fluid removal, even the best dialyzer in the world is restricted by the physiology of the body. The human body can only handle about 400 ml/hour without any complications. Stretch this limit and you are setting yourself up for a variety of problems like cramps, low blood pressure and some heart issues like Myocardial Stunning.

More hours on the machine also means you have less time between treatments. This means lower inter-dialytic weight gains. The normal human body has about 5-6 liters of blood. When someone consumes about 2 liters of fluid without removing it, it means almost 40% extra fluid for the heart to pump. This puts a lot of load on the heart causing it to expand (Left Ventricular Hypertrophy) and eventually fail. That is why most dialysis patients die of Cardiac issues and many of them die during the 'long-gap' between sessions. For patients on thrice a week dialysis, this typically is the 'killer weekend' - the Sunday-Monday gap or the Saturday-Sunday gap.

So, how much dialysis should one get?

I would say, "however much you can practically get!" I get about seven hours each night, six nights a week. That's at least 42 hours per week! Compare this to those who get five hours, twice weekly or four hours, thrice weekly. I get a lot more. Yes, there are a large number of people who have survived for a lot longer than I have on these modalities. But we must not get swayed by a few odd cases. The vast majority of patients who get low hours per week have poor survivals and quality of life.

Even when it comes to toxins, middle molecules can only be removed by more hours on the machine. These are the silent killers when it comes to long term dialysis.

I strongly believe a lot more effort needs to be made by the Indian dialysis community in getting patients more hours on the machine. Yes, patients here have financial constraints. Yes, we have a resource crunch. But if we honestly ask ourselves the question, "Are we giving optimal (not just adequate) dialysis to every patient who can afford it?", I am sure the answer is a big "No".

Are we giving enough hours to patients covered by private insurance? No!

Are we giving enough hours to patients covered by Government reimbursement schemes? No!

Are we giving enough hours to patients to patients who can afford them? No!

Where is the financial constraint for patients here?

I rest my case.

Hello, I'm Kamal from Hyderabad, India. I have been on dialysis for the last 13 years, six of them on PD, the rest on hemo. I have been on daily nocturnal home hemodialysis for the last four and half years. I can do pretty much everything myself. I love to travel and do short weekend trips or longer trips to places which have dialysis centers. Goa in India is a personal favorite. It is a great holiday destination and has two very good dialysis centers.
