Dialysis: how often and for how long?

I’m still working on the BigD holiday arrangements. It’s slow, but looking good.  More soon.

In the interim, some news about dialysis times.

When I started the BigD in 1995, the standard was to dialyse three times a week for 5 hours per time.  I had known that dialysis was on the cards for me since 1972, when I damaged my left kidney in rough seas in the navy, and then discovered that I had only one (the right was missing in action since birth).

I hung on to my dwindling kidney function (via diet and good management by my nephrologist, John Dawborn) for 23 more years.  But I thought my life was over when I began treatment.  Five hours per time, three times per week was a real pain.  All that lost opportunity to do other things, getting restless and feeling unwell after the fourth hour and losing the rest of the day while I recovered.

Like everyone, I desperately wanted to reduce my hours.  My nephrologist held firm.  He was a great believer in the more dialysis I had, the healthier I would be, and 15 hours per week was his absolute minimum.

I regret to report that a new paper published in Medscape Nephrology on 27 December 2011, backs him up with evidence.  Written by Joel D. Glickman, MD, with the electrifying title Nephrologists Unite: Time to Put the ‘t’ back in Kt/V, it has some really interesting news for us BigD-ers.

What is Kt/V?  It’s a ratio indicating the efficiency of each dialysis session.  Put simply, it uses the speed your blood is pumped through the dialyser, and the length of time it is flowing, versus the amount of blood in your body (calculated by your weight) to estimate when you had have enough dialysis to remove the excess urea.  Completely clean blood throughout your body would be a Kt/V of 1.0, where the amount of blood cleaned equals the amount of blood in your body.  If you want to know more, see Wikipedia here.

But there are a couple of things wrong with using the Kt/V ratio to set dialysis time.

Firstly, kidney failure results in a lot of other toxins besides urea (including the so-called middle molecules).  Most can be removed, but efficiency of removal cannot be measured by Kt/V.

Secondly, for a range of reasons the theoretical 1.0 ratio cannot be achieved.  However many kidney organisations and specialists use Kt/V as an indicator dialysis efficiency.  For example, the US National Kidney Foundation Kt/V target is 1.3.

Unfortunately, over time the idea of this ratio has been reversed to:  “If you achieve a Kt/V of 1.3 over three hours, three times per week then you only need 3 three-hour sessions per week.”  Obviously BigD patients grabbed this news with both hands, because it meant shorter times on the machine.

But some nephrologists (like mine and JD Glickman) were sceptical.  Observational data clearly indicated there were benefits in longer treatment times.  Could this be proven?  Along comes the Glickman paper, with some alarming research stats.  Read the paper for details, but in summary, patients whose dialysis sessions were less than 3 hrs had a 60% increase in mortality. And life expectancy improves dramatically as the length of BigD time increases.

Pretty hard to argue with that: shortening your dialysis time shortens your life.  Or to take the positive view, more time on dialysis, more time on planet earth.

Glickman’s absolute minimum is 4 hrs, three times per week, a total of 12 hours – and longer if you can arrange it.

These findings make John Dawborn look pretty smart.  I have been on 15 hrs per week since I started.  And as I said, I really didn’t like it.

But then, a couple of years later he offered an alternative, which actually meant that we could both be happy.  I moved onto 5 days per week dialysis, with only 3 hours each time.  I have written elsewhere about the benefits of more frequent dialysis (which is also backed up by a steadily growing body of research).

I still dialyse for 15 hours per week.  But I can tolerate it, and I am well most of the time.  I still have things I would rather do, but with some planning, I can often do them while I am dialysing.

So, the bad news is that your BigD session isn’t going to get shorter any time soon.  The good news is (1) that you will live longer (for some people it will just feel longer), and (2) there is a way around those long hours and the roller coaster of three times a week.

Maybe it’s time you revisited how long and how often you dialyse?

Arranging International Travel Dialysis

I’ve decided to try another trip to China, as part of a business trip.  My last effort ended badly, when I tripped on slippery tiles on a Hong Kong footpath and fell on my fistula.  It scared the hell out of Julie and me, thinking I had a life-threatening injury in a foreign country, at risk of bleeding to death where I fell.  Luckily we were already on the way to a hospital around the corner for dialysis, and more luckily, they found I had bruised but not ruptured the fistula.  All was well, but the doctor suggested we delay our trip to Beijing.  We cut the trip short and came home.

Well, here it is, almost 2 years later and Julie and I are ready to line up again.  This time we plan to go to both China and Europe for a few weeks in April/May.  We will start with a direct flight from Melbourne to Beijing, stay about 5 days, and then fly to London to do some work and catch up with our No. 2 son.  We will probably stay there for about 12 days travelling to Gloucester in the Cotswolds and perhaps Oxford, then Stockholm, back to London and home.

Here’s how we plan and schedule the dialysis I need at each stop.

Arranging dialysis from a distance is like getting a dentist appointment.  The closer the appointment, the less likely you can get one.  So the Number 1 Rule is to start booking early.

Many countries have two kinds of dialysis centres, public and private.  Some are completely separate (like Australian and the UK); others have private chairs in public units (like in China).  Public dialysis is usually free to the citizens of that country, while everyone must pay to use a private unit.  So visitors like me usually book into private units.

However, not always.  Some countries with public health services have signed reciprocal health care agreements, so that their public hospitals will cover any medically necessary treatment which may be required while in that country, including dialysis, at no charge.  Australia has reciprocal health care agreementswith 11 countries: New Zealand, The United Kingdom, The Republic of Ireland, Sweden, Norway, Finland, The Netherlands, Italy, Belgium, Malta, and Slovenia.

In theory, this is great: cost-free dialysis while travelling the world (or a subset of it).  However, the reality is that in most of these countries, the public health system is super-busy all the time, and their dialysis units are usually operating at full capacity.  I have tried to book into public BigD units around the UK before with zero success, so in the past I have used a private unit (The London Clinic) and limited my travel to day trips close to London.

I have had success in other countries in the group: I have dialysed in public units in both Italy and in Ireland.  The dialysis was safe, expert, and free, and both had a delightful local flavour.

I have another option this time.  My local BigD clinic is a Diaverum clinic, a relatively new group, created 4 years ago by spinning off the Gambro Healthcare clinics in Europe.  I have asked my Unit Manager if it is possible to use the Diaverum clinics in Europe.  Hopefully there could be some benefit in doing this.

Though I dialyse 5 days per week in Melbourne, it is quite difficult to do so when travelling, so I will drop back to four or even three days per week (with increased time at each session, as needed).  So, over the next few weeks we will:

  1. Identify possible dialysis units in each country (public first, then if not available, private – Diaverum, then others), in particular a contact name, phone number and email address (Global Dialysisis the best place to start, it is a wonderful resource for BigD travellers)
  2. Choose suitable dates and if possible, approximate times, based on our flight plan
  3. Prepare an email for each unit, listing our proposed dates and times
  4. Send the emails to my Unit Manager
  5. She will send them on under her name, talking the BigD talk with the contact people and eventually confirming the booking dates and times
  6. Once we get tentative confirmation, we book the flights and accommodation
  7. Ask my Unit Manager to make a last check the itinerary, to make sure I am getting enough dialysis – it’s easy to miss a day when arrangements are constantly changing
  8. Arrange some form of travel insurance (again, we will use the Global Dialysis recommended insurer, to get a quote), though I have found useful cover difficult to get in the past.

Steps 5 and 6 tend to be iterative.  First choice days may not be available and they may suggest others.  This usually means we will have to rework our flight and accommodation bookings.  Eventually they will all mesh and we will be ready to go.

Obviously in addition to getting our China visas (no visas are required for the UK or Sweden) and ensuring our passports are valid, I usually get all my meds packaged in blister packs at the local pharmacy.  This is a great service.  It saves me worrying about all those different plastic pill bottles and packs, and helps minimise questions during drug searches (well I think it will, I have never actually been searched for drugs [though I have had a prostate check... at least that what the doc said it was]).  I usually take at least two extra week’s worth of blister packs, just in case I am delayed anywhere.

It is also useful to the take the contact details of other BigD units at each destination, just in case something falls through.

So, the preparation begins.  I’ll let you know how it progresses.

Starting Dialysis

Over the Christmas holiday time both Peter and Armand left comments about their nervousness starting the BigD, Peter for his soon-to-be wife and Armand for himself.

They are not alone. Everyone gets nervous about starting something as dramatic and alien as the BigD: the needles, being a patient, the machine, watching your blood go round and round through the dialysis kidney, the time commitment – it is a big life change.  Also, most people feel very unwell by the time the starts dialysis, so unwell that they can no longer work or play.  Things feel bleak.

But after a few weeks on the BigD, they begin to feel well again – often well enough to start taking their life back.  And once you get used to the routine (which takes about a month), you begin to realise that dialysis itself is no big deal:  you arrive with toxins in your blood, you sit there for three to four hours then you leave with nice clean blood.  Some people like to think of it as a four hour pee.

So what is the real BigD life change?  It’s the time it takes to make it all happen – usually about 15 hours a week.

When I started, my doctor suggested that I think of the BigD as my second job and to make allowances for getting there each session.  But I worked out pretty quickly that I really have no choice but to be there, it’s not some optional hobby.  So now I think of it as my main job, and I think of family time, my for-pay job, the gym, hobby time, movies, etc as things I can do because of my main job.

So now that you are joining the BigD club, the question is not How much of my life do I have to forego?  Rather it’s How will I refashion my life around this new BigD “job”?  Because of BigD, you still have a life.  So you can review it: do I want to keep doing what I did before, or is this my chance to reassess and reprioritise?  Should I negotiate to reduce my work hours?  Or should I start BigD early and work later?  Maybe change the focus to family, fitness or a new work/home mix?

Life with BigD will not be worse, just different.  It’s your choice how different.

Holiday time

It’s Christmas Day here in Melbourne!  Time for family, reading books to grand kids (and to me) and hopefully next Tuesday, whipping up enough enthusiasm to clean out the garage.

Have a great Christmas everyone.  We’ll get together again in the New Year.



Its hot today: 32 °C (90 °F), which is normal, because summer started here just over a week ago.  Melbourne has a temperate climate, mostly a comfy 22° (68°F), with the occasional dip and blip as the seasons dictate.  Until yesterday we had delightful spring temperatures of 17°C to 22°C (63°F to 68°F); so it has been a big and a quick change.  But no problem!  I will be acclimatised within a couple of weeks and this will be the new norm.

Things were different before I went onto the BigD. I would have begun complaining about now that it was too hot, and not stopped until autumn arrived with some blessed low temperatures.

Not so now that I am a member of the BigD club.  One of the founding directives of the club is that you don’t drink more than about a litre a day of any fluid.  This includes not only water, coffee, tea, fizzy drinks, beer and whisky, but also watermelon, jelly, porridge, rice pudding and any other high fluid food.  This is because without kidneys or kidney function, the fluid has no way to leave the building.  So it stays in your blood, rests in body fat, ankles, lungs and anywhere else that gravity and body cavities allow.  The result is bloat, which is unsightly, uncomfortable and dangerous.  It becomes difficult to breathe, and the added load on your heart can be – and often is – fatal.

I have always liked to guzzle water (or an icy soft drink –not to mention beer – mmm… er, sorry).   From a young age I loved gulping water direct from the tap: cold, wet and plenty of it.  Perhaps I knew that kind of joy would be denied me later in life, so I drank as much as I could before the kidney bell tolled – who knows.  Anyway, now it’s a litre a day, and has been for so long that it is second nature.  I always reach for the smallest glass, half fill it and leave a little in the bottom when I finish.

Most BigD-ers can tell is they have drunk too much.  I know by my wedding ring, which doubles as a body fluid indicator.  Immediately after dialysis, when I’m at my base weight, my fingers are really thin, with very little flesh.  When I interlace them, I can feel the bones and not much else, and it’s possible for me to gradually slide off my wedding ring.  After a day’s break from dialysis, my hands become fleshier, and it sort of feels normal (softer) when I interlace my fingers. There is no way I could get my ring off.  If I have drunk too much, they become quite plump, and I can barely find my wedding ring.

So why do I like summer?  On a hot day, in the sun or the shade, we sweat.  A lot more than we imagine.  I usually have a drink or two of water or tea in the morning and the same in the afternoon.  In summer, each drink seems to evaporate as you swallow it.  On a really hot day, a drink an hour may not keep up with evaporation.  So guess what?  Guzzle time.  Every few hours through the heat of the day: a whole can of lemonade (Coke, with all that potassium is a bridge too far), or even the odd icy beer.  Just like before this BigD business began.  Bliss.

Just writing about this has made me thirsty, and I happen to know that there is a small can of lemonade with my name on it in the fridge.  Roll on summer.  Cheers!
