The NICE guidelines to [HCPs on T2D] are quite clear and this is what they will follow.
I've been point blank told by my GP (and a friend who is a GP, and somewhat fed up with patients who do nothing but take pills and carry on as before) it's my responsibility to manage the condition. Unless on insulin I'm not sure there's any specialist knowledge out there that would benefit us - I was pretty much told at diagnosis to 'lose weight and cut carbs and exercise' which has worked well for me.
I'd say there is a great deal of knowledge and experience about T2D (as well as ignorance!) out there in the medical profession and the research community, as well as prediabetics and T2 diabetics. It just needs a concerted action by knowlegeable people to come up with clear guidance for HCPs and their patients.
The NHS should do this centrally. They need to commission someone who is skilled in the art of putting two and two together to lead the project. The deliverables would be well presented (updateable) online and print media available to everyone before and after diagnosis.
It is ridiculous to expect the thousands of HCPs dealing with T2D to do all this for themselves. Not least if there is only a phone call or 10-30 minute appointment once in a blue moon to convey this information to the hundreds of thousands of people who need it.
Just look at what
NICE expects of its HCPs:
Recommendations
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]
1.2 Education
1.2.1
Offer structured education to adults with type 2 diabetes and their family members or carers (as appropriate) at the time of diagnosis, with annual reinforcement and review. Explain to people that structured education is an integral part of diabetes care.
[2009]
1.2.2
Ensure that any structured education programme for adults with type 2 diabetes:
- is evidence-based, and suits the needs of the person
- has specific aims and learning objectives, and supports the person and their family members and carers to develop attitudes, beliefs, knowledge and skills to self-manage diabetes
- has a structured curriculum that is theory driven, evidence-based and resource-effective, has supporting materials and is written down
- is delivered by trained educators who:
- have an understanding of educational theory appropriate to the age and needs of the person
- are trained and competent to deliver the principles and content of the programme
- is quality assured, and reviewed by trained, competent, independent assessors who measure it against criteria that ensure consistency
- has outcomes that are audited regularly. [2015]
1.2.3
Ensure that education programmes for adults with type 2 diabetes provide the necessary resources to support the educators, and that educators are properly trained and given time to develop and maintain their skills.
[2009]
1.2.4
Offer adults with type 2 diabetes group education programmes as the preferred option. Provide an alternative of equal standard for people who are unable or prefer not to take part in group education.
[2009]
1.2.5
Ensure that education programmes for adults with type 2 diabetes meet the cultural, linguistic, cognitive and literacy needs of people in the local area.
[2009]
1.2.6
Ensure that all members of the diabetes healthcare team are familiar with the education programmes available locally for adults with type 2 diabetes, and that these programmes are integrated with the rest of the care pathway.
[2009]
1.2.7
Ensure that adults with type 2 diabetes and their family members and carers (as appropriate) have the opportunity to contribute to the design and provision of local education programmes for adults with type 2 diabetes.
[2009]
1.3 Dietary advice and bariatric surgery
1.3.1
Provide individualised and ongoing nutritional advice from a healthcare professional with specific expertise and competencies in nutrition.
[2009]
1.3.2
Provide dietary advice in a form sensitive to the person's needs, culture and beliefs, being sensitive to their willingness to change and the effects on their quality of life.
[2009]
1.3.3
Encourage adults with type 2 diabetes to follow the same healthy eating advice as the general population, which includes:
- eating high-fibre, low-glycaemic-index sources of carbohydrate, such as fruit, vegetables, wholegrains and pulses
- choosing low-fat dairy products
- eating oily fish
- controlling their intake of saturated and trans fatty acids. [2009]
1.3.4
Integrate dietary advice with a personalised diabetes management plan, including other aspects of lifestyle modification such as increasing physical activity and losing weight.
[2009]
1.3.5
For adults with type 2 diabetes who are overweight, discuss and agree an initial body weight loss target of 5% to 10%. Remember that a small amount of weight loss may still be beneficial, and a larger amount will have advantageous metabolic impact in the long term.
[2009]
1.3.6
Individualise recommendations for carbohydrate and alcohol intake, and meal patterns. Make reducing the risk of hypoglycaemia a particular aim for people using insulin or an insulin secretagogue.
[2009]
1.3.7
Advise adults with type 2 diabetes that they can substitute a limited amount of sucrose-containing foods for other carbohydrate in the meal plan but should take care to avoid excess energy intake.
[2009]
1.3.8
Discourage adults with type 2 diabetes from using foods marketed specifically for people with diabetes.
[2009]
1.3.9
When adults with type 2 diabetes are admitted as inpatients to hospital or any other care setting, implement a meal planning system that provides consistency in the carbohydrate content of meals and snacks.
[2009]
1.3.10
For recommendations on lifestyle advice, see the
NICE guidelines on preventing excess weight gain,
weight management,
obesity,
physical activity and
tobacco.
[2015]
1.3.11
For recommendations on bariatric surgery for people with recent-onset type 2 diabetes, see the
section on bariatric surgery for people with recent-onset type 2 diabetes in the NICE guideline on obesity.
[2015]
1.4 Diagnosing and managing hypertension
The recommendations on diagnosing and managing hypertension have been removed. For recommendations on hypertension in people with type 2 diabetes, see the
NICE guideline on hypertension in adults. Diagnosis, treatment and monitoring of hypertension is broadly the same for people with type 2 diabetes as for other people. When a different approach is needed for people with type 2 diabetes, this is specified in the hypertension guideline.
1.5 Antiplatelet therapy
1.5.1
Do not offer antiplatelet therapy (aspirin or clopidogrel) to adults with type 2 diabetes without cardiovascular disease.
[2015]
1.5.2
For guidance on the primary and secondary prevention of cardiovascular disease in adults with type 2 diabetes, see the
NICE guidelines on cardiovascular disease and
acute coronary syndromes.
[2015]
1.6 Blood glucose management
HbA1c measurement and targets
Measurement
1.6.1
Measure HbA1c levels in adults with type 2 diabetes every:
- 3 to 6 months (tailored to individual needs) until HbA1c is stable on unchanging therapy
- 6 months once the HbA1c level and blood glucose lowering therapy are stable. [2015]
1.6.2
Measure HbA1c using methods calibrated according to International Federation of Clinical Chemistry (IFCC) standardisation.
[2015]
1.6.3
If HbA1c monitoring is invalid because of disturbed erythrocyte turnover or abnormal haemoglobin type, estimate trends in blood glucose control using one of the following:
- quality-controlled plasma glucose profiles
- total glycated haemoglobin estimation (if abnormal haemoglobins)
- fructosamine estimation. [2015]
1.6.4
Investigate unexplained discrepancies between HbA1c and other glucose measurements. Seek advice from a team with specialist expertise in diabetes or clinical biochemistry.
[2015]
Targets
NICE has produced a
patient decision aid on agreeing HbA1c targets, which also covers factors to weigh up when discussing HbA1c targets with patients.
1.6.5
Discuss and agree an individual HbA1c target with adults with type 2 diabetes (see recommendations 1.6.6 to 1.6.10). Encourage them to reach their target and maintain it, unless any resulting adverse effects (including hypoglycaemia), or their efforts to achieve their target impair their quality of life. Think about using the NICE patient decision aid on weighing up HbA1c targets to support these discussions.
[2015, amended 2022]
1.6.6
Offer lifestyle advice and drug treatment to support adults with type 2 diabetes to reach and maintain their HbA1c target (see
the sections on dietary advice and bariatric surgery and
choosing drug treatments). For more information about supporting adherence, see the
NICE guideline on medicines adherence.
[2015]
1.6.7
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]
1.6.8
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. [2015]
1.6.9
Consider relaxing the target HbA1c level (see recommendations 1.6.7 and 1.6.8 and
NICE's patient decision aid) 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]
1.6.10
If adults with type 2 diabetes reach an HbA1c level that is lower than their target and they are not experiencing hypoglycaemia, encourage them to maintain it. Be aware that there are other possible reasons for a low HbA1c level, for example deteriorating renal function or sudden weight loss.
[2015]
1.6.11
For guidance on HbA1c targets for women with type 2 diabetes who are pregnant or planning to become pregnant, see the
NICE guideline on diabetes in pregnancy.
