To clarify, the NHS is a VERY risk averse organisation. And a home-built dialysis machine is a very risky machine to build and use. Well done to the doc.
Very courageous, and incredible initiative by the doc! (I can imagine a number of docs thinking about how they could do it, but this guy actually made it happen.)
Nobody gets in trouble for following the rules. Besides, the NHS, as an organization, sees thousands of dead babies a year, why should it care about another?
Risk-averse organizations fall into the same category as people who would decide not to throw the lever, because if they don't take any action, then they aren't responsible for any of the consequences (which is stupid, imo).
