Q

what are the NICE guidelines on relaxing the target HbA1c level on a case-by-case basis?

A

1.1 Individualised care
1.1.1 Adopt an individualised approach to diabetes care that is tailored to the needs and circumstances of adults with type 2 diabetes, taking into account their personal preferences, comorbidities and risks from polypharmacy, and their likelihood of benefiting from long-term interventions. Such an approach is especially important in the context of multimorbidity. [2015, amended 2022]

1.1.2 Reassess the person’s needs and circumstances at each review and think about whether to stop any medicines that are not effective. [2015]

1.1.3 Take into account any disabilities, including visual impairment, when planning and delivering care for adults with type 2 diabetes. [2015]

Assess cardiovascular risk Remove any that are contraindicated Of the remaining what are the pros and cons Select the preferred choice. 5. Agree a review date and the target HbA1c with the patient
105
describe the set a goal phase?

106
HbA1c targets?
For adults whose type 2 diabetes is managed either by lifestyle and diet, or lifestyle and diet combined with a single drug not associated with hypoglycaemia, support them to aim for an HbA1c level of 48 mmol/mol (6.5%). For adults on a drug associated with hypoglycaemia, support them to aim for an HbA1c level of 53 mmol/mol (7.0%). [2015] In adults with type 2 diabetes, if HbA1c levels are not adequately controlled by a single drug and rise to 58 mmol/mol (7.5%) or higher: reinforce advice about diet, lifestyle and adherence to drug treatment and support the person to aim for an HbA1c level of 53 mmol/mol (7.0%) and intensify drug treatment.
107
what should be considered when relaxing targert HbA1c level?
Consider relaxing the target HbA1c level on a case-by-case basis and in discussion with adults with type 2 diabetes, with particular consideration for people who are older or frailer, if: they are unlikely to achieve longer-term risk-reduction benefits, for example, people with a reduced life expectancy tight blood glucose control would put them at high risk if they developed hypoglycaemia, for example, if they are at risk of falling, they have impaired awareness of hypoglycaemia, or they drive or operate machinery as part of their job intensive management would not be appropriate, for example if they have significant comorbidities. [2015, amended 2022]
108
“Take 5” Are there other factors that should be prioritised over HbA1c?
109
Are the current treatments optimised?

110
What are the glucose lowering options?
Remove any that are contraindicated. Of the remaining what are the pros and cons? Asses cardiovascular risk Does the individual have severe albuminuria? Select the preferred choice.
