I considered posting this in another thread, but didn't want to go off topic - it looked so exciting... talking about diet again...So, here goes:
Recommendation 16 in NICE Guidelines CG66 (published in 2008) says
NICE Guidelines CG66 said:
R16 When setting a target glycated haemoglobin HbA1c:
- involve the person in decisions about their individual HbA1c target level, which may be above that of 6.5 % set for people with Type 2 diabetes in general
- encourage the person to maintain their individual target unless the resulting side effects (including hypoglycaemia) or their efforts to achieve this impair their quality of life
- offer therapy (lifestyle and medication) to help achieve and maintain the HbA1c target level
- inform a person with a higher HbA1c that any reduction in HbA1c towards the agreed target is advantageous to future health
- avoid pursuing highly intensive management to levels of less than 6.5 %.
My reading is that the target should be personalised and that it will be the exception rather than the norm to set it above 6.5%. However, intensive management (whatever that is) should not be pursued to maintain an HbA1c below 6.5%.
NICE guidelines CG87 (published in 2009) discuss at which point specific medications should be prescribed and use the 6.5% and 7.5% boundaries as points at which to use those medications should be prescribed and therefore shouldn't be used to indicate what targets should be.
DUK suggest a target HbA1c for children of 8.5%, but it's down to the paediatric care team to set targets. NICE Guidelines CG15 (published in 2004 and revised in 2009 and 2010), however, suggest a target of less than 7.5%.
For adults with type 1 NICE Guidelines CG15 say:
NICE Guidelines CG15 said:
Blood glucose control should be optimised towards attaining DCCT-harmonised HbA1c targets for prevention of microvascular disease (less than 7.5%) and, in those at increased risk, arterial
disease (less than or equal to 6.5%) as appropriate, while taking into account:
- the experiences and preferences of the insulin user, in order to avoid hypoglycaemia
- the necessity to seek advice from professionals knowledgeable about the range of available meal-time and basal insulins and about optimal combinations thereof, and their optimal use
DUK's recommendations for adults with diabetes are in line with those from NICE:
DUK said:
For most people with diabetes, the HbA1c target is below 6.5 per cent, since evidence shows that this can reduce the risk of developing diabetic complications, such as nerve damage, eye disease, kidney disease and heart disease.
In 2009 the Quality Outcomes Framework (the means by which GPs are measured and rewarded) required practioners to
Medical News Today said:
...lower blood glucose levels in half of their patients with type 2 diabetes to below 7%
As for pre and post prandial blood glucose targets, DUK say
DUK said:
There are many different opinions about the ideal range to aim for. As this is so individual to each person, the target levels must be agreed between the person and their diabetes team.
I'm not sure where our HCPs dream up their targets, it sure isn't from NICE, nor from DUK, and not from QOF. I must be relatively lucky then, my GP is happy for me to be in the 5% club.
