Honestly its been a life changer for me, even being a IDDM Type1 for 40 years this little devilish gadget taught me some new tricks!
On intensive insulin therapy (like I believe most Type1s are these days) I typically would punch my fingers 5-6 times a day to maintain good bg control. So just the economical business case to have this device is positive, as the breakeven point for the costs aspect alone is around 5 finger prick measure sticks/day based on my local prices for the required alternatives. And when one also consider the improved therapy results and the increased quality of life for the patient, it should be obvious for everybody involved (all stakeholders, from state, health authorities, to healthcare providers, to patients and their relatives) that this device should replace the old fashioned bg test sticks asap for every body needing more than 3 tests a day to maintain their proper bg levels!
Mind you, I am not living in the UK. But I have long since dropped using any other bg meter after getting onto the Libre, and fully rely on it for everything I do, driving, diving, skiing, traveling, etc etc. And as far as I know, then all T1 diabetics here in Belgium have been switched entirely.
We should not need to be admitted to the A&E in coma before we get the tool we need to live a decent life!
