Most of the developments happened in the USA where greed and financial advantages were the key force to bring about developments and improvements. Without that greed dialysis might still be where we were in the 1960's and I'd be dead by now.
Talking about dialysis in a movie....the other day I was watching Star Trek 7 (I think it was 7)...the one where they go back into the past to 'our days' to save a whale.....well anyway...at a certain point they go into a hospital and Dr.McCoy sees this old lady and asks her whats wrong with her...she says 'I'm on dialysis'....and he answers 'Dialysis? What is this the middile ages?' then gives her a pill and says 'you'll be fine with this! lol Got to love Star Trek!
Forgive me for not expanding such a provocative statement. By the time that Medicare opened its doors to essentially all dialysis patients in 1973, 90% of those on dialysis dialyzed at home for 6-8 hours, three times a week. Once Medicare began to pay, dialysis times became shorter and more violent in a peculiar dialysis American style not seen elsewhere in the developed world.
Dr. Kolff, the inventor of the first clinically effective dialysis machine freely gave his invention away. Dr. Scribner likewise freely gave his advancements away.
It seems to me that Hemodoc and I can look at the same story and reach diametrically opposite conclusions. Such is the basis of healthy debate.Quote from: Hemodoc on May 29, 2010, 01:54:26 AMForgive me for not expanding such a provocative statement.

Once Medicare began to pay, dialysis times became shorter and more violent in a peculiar dialysis American style not seen elsewhere in the developed world. What Hemodoc is saying is that dialysis was better for taking 6-8 hours at home rather than the current 3-4 in center, that the change was for the worse for the patient and was a consequence of the drive for profit and the greed of big business.I think there is a better explanation. Dialysis machines and membranes in particular were vastly improved from the mid 60's. The improvement meant that the patient on newer machines needed less time to achieve the same result. For instance, the twin coil dialyser used by the Bringham group in the 1960's needed 1500 ml of blood in the coil, which had to be saved between sessions.The reason for the large proportion on home dialysis was that Dr. Scribner was turned down by the hospital administration when he applied to expand his unit. He could only add more patients by modifying his procedures so that they could dialyse at home.Quote from: Hemodoc on May 29, 2010, 01:54:26 AMDr. Kolff, the inventor of the first clinically effective dialysis machine freely gave his invention away. Dr. Scribner likewise freely gave his advancements away.Those assertions are misguided.Dr Kolff was professor of surgery and research professor of engineering at the University of Utah. Dr. Scribner was employed by the University of Washington. It is normal for inventions made in the course of employment to belong to the employer, not the employee. Their inventions were not theirs to give away. Since the employers were public organizations, the public, in effect, already owned the inventions. I am certain that if the two good men were employed in the private sector, their inventions would never have been given away.Of course, Hemodoc's main point , that some dialysis developments were not initiated by profit and greed motives, is still valid, but for some, not all developments. But I never said it was. My point it that the development of production quantities of machines and membranes could only take place where finance is available. It's only available where profits can be made. That's why without it, dialysis would still be stuck in the 1960's and 70's.
Stoday, simply because you oppose my views on evolution and religion, you bring up a worthless accusation against my simple statements
