I'll base this decision on the evidence and stats I can get during the assessment and consultation stage.
I need to look into the actual stats of complications but this is one of the reasons I think I'd prefer a non-directed donation, I'd prefer not to know if it was unsuccessful.
That's all I am saying is to examine this properly but
yourself. It is a 'safe' procedure or it wouldn't be allowed to continue. We don't really know the proper complication rate - all the studies are quite faulty for a variety of reasons most of which they can't control. Figures may be given to you - the often quoted 1:3000 0.3% mortality rate - people will mention that in some studies long-term survival is show to be better in donors - some studies will show a lot worse. You will most likely be younger than most donors though, healthier all around and importantly not obese. This all works in your favour and for that of the recipient.
I am presuming you are quite educated and would rightly be sceptical of a piece of scientific research that is done on the behest of an interested party. Therefore, it matters not what I say or the people who will treat you fairly but are not impartial at the meetings. Look up the figures yourself they are out there:
Is the study done in one centre - could a good or bad surgeon be changing the results?
Is the technique used in the study the same as the one they use at Southampton?
How long ago was the study?
Who will be performing your actual procedure - the consultant, the reg or will they talking a junior through the process?
What is there mortality rate?
What is their major complication rate?
What is their minor complication rate?
Do the minor complications actually to you seem more than that - what medically may be defined as minor may be to you not that way eg incontinence etc.
How long were the donors tracked for?
Was there a good control group?
What will the success rates be for the recipient - again these figures are out there but generally they are excellent?
I am just saying you need to figure this out yourself and whilst trusting the people you are meeting recognising they were all trained by the same people for the same purpose. Look at the studies were they done by people who seem junior, were they done in a reputable centre etc. See how that relates to the whole then ask Southampton how they compare.
Like I said it is a safe procedure but all safe procedures carry risks. You are taking a preventable risk for a very noble reason. If you go ahead then go ahead fully informed because that is the only true consent. You can't really trust anyone else to do that for you on something this big.
For what it's worth I'll offer my perspective from a different angle:
Would I donate to my wife - yes because I love her.
Would I donate to my kids - yes because they are my world.
Would I donate to a friend or family member - yes because I know it's likely safe and because I care for these people.
Would I donate to a stranger - no because there is some risk that a) one of the above may need my help b) I would be unlucky and it would cause distress for those I've just mentioned.
Whatever you chose I think your a very noble person for even considering it. All I will say now is I have a few medals on my wall for doing things where I reacted rather than thought things through - my kids think they are 'epic' - however now after thinking about those times I just think how things may have turned out and how recklessly irresponsible I was at those moments.
I suppose this is the difference between people that donate to an aid campaign like Ebola and those who take the risk to go out to these countries with MSF.
Both my wife and I have been out there - see above last paragraph. And then look at Mr Pooley - see how much training he did post qualification what his experience he was then calculate how many people he placed at risk at the Royal Free and how much his illness cost the NHS. Doing good isn't always enough Burnsy I've mentioned this time and time again on these forums in relation to interactions especially medical one has to weigh the good with the potential for harm. A lot of this comes with hindsight unfortunately.
