She also said that she would like every patient of hers to have the FSL flash glucose meter.
I am sure that would be a good thing too, but unless you can persuade everyone to pay more in taxes, to do so would mean taking that money away from caring from other health conditions. And for the amount of testing the overwhelming majority of type 2 diabetics would require for good control they are more expensive than prescribing glucometer strips. And most of them do not even get that.
Whilst I can only guess at the numbers, I would assume the majority do not even pay for their own testing, it is easy to get a different perspective on forums but they are only used by a tiny percentage of diabetics. There would need to be something exceptional about someone's situation for them to need continuous monitoring to retain good control.
There are approximately 3.4 million people in the U.K. diagmosed with type 2 diabetes, if everyone was prescribed a Freestyle Libre that would cost the N.H.S. £3.1 billion in sensors. That being the cost of one per person every two weeks at £35. Even if you generously halve the cost due to the level of bulk buying, that is still a lot of money that needs to be found to cover it. And that is not including the around 350,000 type 1 diabetics, of which the majority are also unable to get a C.G.M. prescription because of the cost.
I am not criticizing the technology, it is undoubtably a good thing for those who need to manage their own insulin. The problem for me is your insistence on its necessity, particularly for type 2 diabetics where there is not the immediate danger of ensuring you do not let your levels go too low.
And this seems in part spurred on by webinars which, from the way you come across, seem to make you think it is impossible to get good control any other way. It is a bit worrying that you think health care worked would push bad advice to stay in work, but that a commercial company pushing their products are beyond question. A healthy scepticism of both is reasonable, but such a contrast between the two reactions is quite worrying. It is quite possible, indeed likely, that the recommendation regarding tonsils changed, as is normal in science and medicine, though greater understanding. And that while a Freestyle Libre is a helpful device, it is not a necessity for the majority of type 2 diabetics.
Incidentally, the change in the scale of HbA1c went from using percentages to mmol/mol. The old system was based on a major U.S. trial called the Diabetics Control and Complications Trial, so the percentages are referred to as being DCCT aligned.
However because different countries used different scales, in order to produce an international standard the International Federation of of Clinical Chemistry adopted using a measurement of the number of millimoles of glucose that had bonded with a mole of haemoglobin. So a few years ago the U.K. switched to using that system, although blood test results (at least mine) report both. Personally I was diagnosed towards the end of using DCCT so I tend to prefer percentages.
