To be brutally honest, the guideline on testing is driven by financial interest rather than patient oriented benefit. If the NHS had to pay for meters/strips and appropriate education for use of said then the service would be bankrupted. HCPs should be honest with patients, they should stop saying 'Don't test, you'll become anxious/obsessed/depressed' and be open citing funding as the main reason.
There is a caveat also that to prescribe a meter and strips relies on the patient using dietary changes in an effort to manage bg even if they are not on bg lowering medication and this itself would be reliant on good sound nutritional advice.
