Ministry of Health Clinical Practice Guidelines: Diabetes Mellitus

Abstract

The Ministry of Health (MOH) have updated the clinical practice guidelines on Diabetes Mellitus to provide doctors and patients in Singapore with evidence-based treatment for diabetes mellitus. This article reproduces the introduction and executive summary (with recommendations from the guidelines) from the MOH clinical practice guidelines on Diabetes Mellitus, for the information of SMJ readers. Chapters and page numbers mentioned in the reproduced extract refer to the full text of the guidelines, which are available from the Ministry of Health website: http://www.moh.gov.sg/content/moh_web/healthprofessionalsportal/doctors/guidelines/cpg_medical.html. The recommendations should be used with reference to the full text of the guidelines. Following this article are multiple choice questions based on the full text of the guidelines.

1.1 Objectives and scope of guideline

The first edition of the MOH clinical practice guidelines on diabetes mellitus for Singapore was published in 1999. Since that time, more facts about this important condition have emerged, not only with regard to its diagnosis and treatment, but also about whether or not type 2 diabetes may be prevented, and, if so, how this may be achieved.

As diabetes mellitus has great public health significance in developed countries and developing nations alike, managing it properly involves a consideration, not just of clinical issues, but also of health economics. This second edition of the guidelines attempts to address some of these complex issues wherever evidence-based information pertaining to them is available.

1.2 Target group

The main aim of these guidelines is to help physicians make sound clinical decisions about diabetes mellitus by presenting up-to-date information about diagnosis, classification, treatment, outcomes, and follow-up.

These guidelines are developed for all health care professionals in Singapore. We hope they would be helpful especially to primary care physicians who care for patients with diabetes mellitus.

1.3 Guideline development

These guidelines have been produced by a committee of endocrinologists, family practitioners and primary care specialists, ophthalmologist, dietitian, social worker, and patient representative, appointed by the Ministry of Health. They were developed by the adaptation of existing guidelines, by the review of relevant literature and by expert clinical consensus with consideration of local practice. The guidance does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or guardian or carer.

1.4 What’s new in the revised guidelines

The following is a list of the major revisions and additions to the previous guidelines:

• In Chapter 3, we have explained the rationale for criteria in diagnosing diabetes. In particular, for asymptomatic patients with a first test that meets criteria, we have attempted to provide more clarity on how to choose a second test, and how to interpret the findings.

• Chapter 4 is a new chapter which brings emphasis to two areas contributing towards positive outcomes in diabetes care: diabetes self-management education, and psychosocial assessment and holistic care of the person with diabetes.

• Chapter 5 on pharmacotherapy in diabetes mellitus has been updated to take into account recent clinical trial evidence of the efficacy of the newer classes of pharmacological agents.

• Chapter 6 focuses on glycaemic control, and emphasizes the importance of individualised targets, balancing the benefits of achieving targets without incurring undue risk of hypoglycaemia or other adverse effects, and considering the risk profile of the patient.

• In Chapter 7 on prevention of cardiovascular disease in diabetes mellitus, recommendations on decision-making in the area of therapeutics have been updated and harmonised with current local guidance on lipid, blood pressure and cardiovascular management. Target blood pressure ranges and LDL levels are discussed, as well as the role of antiplatelet therapy.

• Chapter 8 on prevention and management of diabetic nephropathy has been revised to present recent clinical trial evidence regarding the efficacy of, and indications for, the use of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers.

• Chapter 9 on the prevention and management of eye complications has been updated to include developments such as intravitreal injection of anti-vascular endothelial growth factor in patients with diabetic macular oedema.

• Chapter 11 on pre-gestational and gestational diabetes has been updated. Women at high risk for gestational diabetes, but who are not found to have glucose intolerance in early pregnancy, are now recommended to be re-evaluated with a 75 gram OGTT at 24–28 weeks gestation.

• Chapter 13 is a new chapter outlining key principles in the management of the adult with type 1 diabetes, relevant to the primary care healthcare professional.

1.5 Review of guidelines

Evidence-based clinical practice guidelines are only as current as the evidence that supports them. Users must keep in mind that new evidence could supersede recommendations in these guidelines. The workgroup advises that these guidelines be scheduled for review four years after publication, or earlier if new evidence emerges that necessitates substantive changes to the recommendations.

Future revisions may include management of hypoglycaemia in persons with diabetes, and evolving areas like bariatric surgery and pancreas/islet cell transplantation.

EXECUTIVE SUMMARY OF RECOMMENDATIONS

Details of the recommendations listed can be found in the main text as the pages indicated.

Diagnosis and screening of diabetes mellitus in Singapore

• D In patients with hyperglycaemic crisis, diabetes mellitus can be diagnosed without further testing (pg 42).

  Grade D, Level 4

• B In patients with typical symptoms, diabetes mellitus can be diagnosed if any one of the following is present.

  1. Casual plasma glucose >11.1 mmol/l
  2. Fasting plasma glucose >7.0 mmol/l
  3. 2-hour post-challenge plasma glucose >11.1 mmol/l

Other individuals should have a repeat test on a subsequent day (pg 42).

Grade B, Level 2⁺⁺

• D When two different tests are available for the same patient and the results for both tests are above the diagnostic thresholds, the diagnosis of diabetes is confirmed (pg 42).

  Grade D, Level 4

• D When two different tests are available in an individual and the results are discordant, the test whose result is above the diagnostic cut point (usually the fasting plasma glucose or 2-hour post-challenge glucose) should be repeated (pg 42).

  Grade D, Level 4

• D Fasting plasma glucose measured in an accredited laboratory is the preferred test for the diagnosis of diabetes mellitus (pg 43).

  Grade D, Level 4

• B All subjects with fasting plasma glucose from 6.1 to 6.9 mmol/l should undergo a 75 g oral glucose tolerance test to determine if they have impaired glucose tolerance or diabetes mellitus (pg 43).

  Grade B, Level 2⁺⁺

• D If a second test fails to confirm the diagnosis, barring a laboratory error, such patients are likely to have test results near the margins of the threshold for a diagnosis. The healthcare professional might opt to follow the patient closely and repeat the testing in 6–12 months (pg 43).

  Grade D, Level 4

• GPP HbA_1c is not recommended as a screening and diagnostic tool for diabetes mellitus until its performance in our multi-ethnic population has been evaluated (pg 43).

  GPP

• B Intermediate states of glucose metabolism termed impaired fasting glucose and impaired glucose tolerance should be recognised as defined in Table 1 (pg 46).

  Grade B, Level 2⁺⁺

• D Screening should be considered in adults of any age who have one or more risk factors for diabetes. In those without risk factors, testing should begin at 40 years (pg 47).

  Grade D, Level 4

• D Subsequently, screening should be carried out every three years for those with normal glucose tolerance and annually for those with impaired fasting glycaemia (IFG) or impaired glucose tolerance (IGT) (pg 47).

  Grade D, Level 4

Lifestyle modification

• D Individuals who have diabetes should receive individualised medical nutritional therapy as needed to achieve treatment goals, preferably provided by a dietitian familiar with the components of diabetes medical nutrition therapy (pg 49).

  Grade D, Level 4

• GPP Special attention should be paid to the diabetic patient’s dietary requirements during periods of sickness, fasting, travel and exercise (pg 49).

  GPP

• D A diet for diabetes should contain a good balance of carbohydrate, protein and fat, adjusted to meet the individual’s metabolic goals and preferences (pg 50).

  Grade D, Level 4

• D Individualised meal planning for diabetes should include optimisation of food choices to meet recommended dietary allowance for all micronutrients, providing adequate vitamins and minerals (pg 50).

  Grade D, Level 4

• B Meal and snack carbohydrate intake for diabetes should be consistently distributed throughout the day, on a day to day basis, as consistency in carbohydrate intake has been shown to result in improved glycaemic control (pg 50).

  Grade B, Level 2⁺

• D Consumption of macronutrients is based on recommended dietary allowance (RDA) for healthy eating; 50–60% of total energy from carbohydrates should be encouraged (pg 50).

  Grade D, Level 4

• B If weight reduction is needed, it should be attempted gradually (0.25 to 1.0 kg/week). In overweight or obese patients with type 2 diabetes, a weight loss of 5–10% of body weight achieved through lifestyle interventions is a realistic goal (pg 51).

  Grade B, Level 2⁺

• D Dietary protein intake of approximately 15–20% of daily energy intake is appropriate for most patients with type 2 diabetes (pg 51).

  Grade D, Level 4

• D It is recommended that total calories from fat intake be kept to <30% of total calorie intake in diabetic patients (pg 51).

  Grade D, Level 4

• D Trans fats should be limited to 1% of total energy intake and cholesterol intake (<200 mg daily) to reduce risk for cardiovascular disease. These goals are similar for individuals with pre-existing cardiovascular disease (pg 52).

  Grade D, Level 4

• B Recommendations for fibre intake for people with diabetes are similar to the recommendation for the general population. A daily consumption of a diet containing 20–35 g of dietary fibre from a wide variety of food sources is recommended (pg 52).

  Grade B, Level 2⁺

• D Sodium intake should be restricted to <2 g per day for diabetic individuals with hypertension (pg 52).

  Grade D, Level 4

• D Diabetes patients with poor glycaemic control or are overweight should abstain from alcohol. If individuals choose to drink, intake should be limited to a moderate amount, as per the general population (no more than two drinks for women per day and no more than three drinks per day for men) (pg 52).

  Grade D, Level 4

• B Individuals who choose to use non-nutritive sweeteners should be advised that some of these products might contain energy and carbohydrate from sources that might need to be accounted for (pg 52).

  Grade B, Level 2⁺

• D For exercise more vigorous than brisk walking, a pre-exercise physician evaluation is recommended for individuals with diabetes to identify cardiovascular risks and any complications of severe neuropathy or severe diabetic retinopathy that may contraindicate certain activities and predispose to injury (pg 53).

  Grade D, Level 4

• D Individuals with severe proliferative diabetic retinopathy should avoid activities that greatly increase intraocular pressure and risk of haemorrhage (pg 54).

  Grade D, Level 3

• B Individuals with peripheral neuropathy and without acute ulceration may participate in moderate weight-bearing exercise. Comprehensive foot care, use of appropriate footwear and daily foot check is recommended (pg 54).

  Grade B, Level 2⁺

• B Individuals with type 2 diabetes should undertake at least 150 mins/week of moderate to vigorous aerobic exercise spread out during at least 3 days of the week, with no more than 2 consecutive days between bouts of exercise (pg 54).

  Grade B, Level 1⁺

• D Individuals with diabetes, especially those on insulin treatment or secretagogues, may require medication dose adjustments and should receive specific education on the prevention of exercise induced hypoglycaemia (pg 55).

  Grade D, Level 4

• C Individuals with diabetes should be encouraged to stop smoking (pg 55).

  Grade C, Level 3

• B People with diabetes should receive Diabetes Self-Management Education (DSME) when their diabetes is diagnosed and as needed thereafter (pg 57).

  Grade B, Level 2⁺

• D Assessment of psychological and social wellbeing should be included as an ongoing part of diabetes management (pg 59).

  Grade D, Level 4

• D Clinicians should provide the following psychosocial support to patients during the diagnosis phase of diabetes management:

  • Provide medical information and psychological support.
  • Be accessible and sensitive to patient’s needs.
  • Provide information and repeat if necessary as they may not retain much at this stage.
  • Introduce to other patients to get them support and an accepting environment
  • Involve other family members if necessary (pg 59).

  Grade D, Level 4

• D Clinicians should provide the following psychosocial support to patients during the maintenance phase of diabetes management:

  • Motivate patient and family to maintain optimal control
  • Create an individualised workable regimen and help patient adhere to it

  • Check for signs of diabetes burnout
  • Consider educational intervention
  • Follow up and review behavioural changes
  • Modify treatment if necessary (pg 60).

  Grade D, Level 4

• D Clinicians should provide the following psychosocial support to patients during the complications phase of diabetes management:

  • Giving them the space to vent and providing them with a lot of realistic reassurance is important
  • Do not overwhelm with information but allow for grieving first
  • Gentle motivation to encourage patients to maintain adherence to treatment regimen and possibly revising some of the information or education will be helpful
  • Counselling is important but needs to be timely (pg 60).

  Grade D, Level 4

• D Patients with diabetes should be encouraged to find support from other persons and families living with diabetes and community programmes which reinforces diabetes education and promotes living well with diabetes. These community based programmes provide a safe and accepting environment for learning and sharing with others who live with the same condition (pg 60).

  Grade D, Level 4

Pharmacotherapy

• B Long-acting sulphonylureas e.g., chlorpropamide and glibenclamide, carry a high risk of hypoglycaemia and are not recommended (pg 62).

  Grade B, Level 2⁺⁺

• A Patients with type 2 diabetes may initially be treated with lifestyle modification (diet and exercise) unless they are symptomatic or severely hyperglycaemic (i.e. random blood glucose >15 mmol/l or fasting blood glucose >10 mmol/l) – in which case pharmacological therapy should be initiated together with lifestyle intervention (pg 63).

  Grade A, Level 1⁺

• A Oral glucose lowering agents should be started if glycaemic targets are not achieved in a timely and appropriate manner (pg 63).

  Grade A, Level 1⁺

• A If glycaemic targets are not reached with a single oral agent, combination therapy with one or more agents (including insulin) from other classes may be considered. However, one would need to monitor carefully for adverse events such as hypoglycaemia or fluid retention (pg 63).

  Grade A, Level 1⁺

• A Insulin therapy should be considered, if optimal combination therapy fails to attain target control (i.e., 2 consecutive HbA_1c values failed to reach ≤ 8% over 3–6 months interval) (pg 63).

  Grade A, Level 1⁺

• A Metformin is usually considered first-line pharmacotherapy, and sulphonylureas/dipeptidyl peptidase 4 (DPP-IV) inhibitors/alpha-glucosidase inhibitors are reasonable alternatives as first-line pharmacotherapy (pg 64).

  Grade A, Level 1⁺

• A For type 2 diabetes, two or more oral agents, or insulin therapy, either alone or in combination with oral agents, may be required (pg 64).

  Grade A, Level 1⁺

• A For type 2 diabetes, other oral agents are acceptable alternatives to metformin as initial monotherapy, if the person does not tolerate metformin, or where metformin is contraindicated (pg 64).

  Grade A, Level 1⁺

• A In the setting of severely uncontrolled type 2 diabetes (for example, HbA_1c >10%, random glucose levels consistently above 16.7mmol/L), the presence of ketonuria, or symptomatic diabetes with polyuria, polydipsia and weight loss, insulin therapy in combination with lifestyle intervention may be the initial treatment of choice (pg 64).

  Grade A, Level 1⁺

• D In elderly patients, initiating therapy with low-dose, short-acting oral glucose lowering agents is recommended (pg 65).

  Grade D, Level 4

• D Metformin is usually contraindicated in the presence of severe renal or hepatic insufficiency as it may be associated with lactic acidosis (pg 65).

  Grade D, Level 4

• D It is advisable to use metformin with caution in those at risk of a sudden deterioration in renal function and those with eGFR <45ml/min/1.73m² and to cease metformin usage if the eGFR is below 30ml/min/1.73m² (pg 65).

  Grade D, Level 4

• D Metformin must be used with care in the presence of co-morbid conditions which increase the risk of lactic acidosis (e.g., class III or IV cardiac failure) (pg 66).

  Grade D, Level 4

• D Thiazolidinediones (in particular, rosiglitazone) are contraindicated in patients with acute coronary syndrome, ischaemic heart disease, and all classes of heart failure (including New York Heart Association (NYHA) Functional Classification Class I/II heart failure patients) and are also not recommended for use in patients with peripheral arterial disease (pg 66).

  Grade D, Level 4

• GPP Treatment choices should be individualised and culturally appropriate, and patients should have the opportunity to make informed decisions on their care and treatment options, in partnership with their healthcare providers (pg 67).

  GPP

• D The use of exenatide is not recommended in type 2 diabetes patients with a history of pancreatitis (pg 68).

  Grade D, Level 4

• A All patients with type 1 diabetes must receive insulin. Multiple daily injections (3 or more) or the use of continuous subcutaneous insulin infusion (CSII or insulin pump therapy) may be required to achieve target glucose levels (pg 68).

  Grade A, Level 1⁺

• D Patients on insulin must be equipped not only with the skills of insulin administration, but also should be educated on self-monitoring of blood glucose, hypoglycaemia management, matching of insulin dose and carbohydrate intake, and dose adjustments during sick days, travel, exercise, and changes in food intake (pg 68).

  Grade D, Level 4

• B Insulin therapy should be managed with relevant and regular insulin and hypoglycaemia-related self-management training with the common goal of improved glycaemic control and reduction in risk of severe hypoglycaemia (pg 69).

  Grade B, Level 2⁺⁺

• D In type 2 diabetes, introduction of insulin should not be delayed if metabolic control becomes suboptimal. This may be initiated as a bedtime dose of intermediate-acting or long-acting insulin with maintenance of oral agents during the day (pg 75).

  Grade D, Level 4

• D When glycaemic control is not achieved despite the addition of basal insulin to oral agents, discontinuing sulphonylureas and switching to premixed twice daily or basal-bolus insulin regimens becomes necessary. However, metformin and a-glucosidase inhibitors may still be used in conjunction with exogenous insulin to attenuate the insulin dose. Fine-tuning of insulin doses is best determined by home blood glucose monitoring. Patients with type 2 diabetes who are switched to insulin therapy temporarily during episodes of acute stress, such as sepsis, may be put back on oral agents when their glycaemic control improves with declining insulin resistance and glucotoxicity (pg 75).

  Grade D, Level 4

Glycaemic control: assessment and targets

• B Self-monitoring of blood glucose is recommended for patients with type 1 or type 2 diabetes who are using insulin (pg 77).

  • Those who have failed to achieve glycaemic goals
  • Those undergoing fasting, for example, during Ramadan (pg 78).

  Grade D, Level 4

• B Self-monitoring of blood glucose should be carried out 3 or more times daily for patients with type 1 diabetes (pg 79).

  Grade B, Level 2⁺⁺

• GPP For patients with unstable metabolic control, changes in daily routine, alterations of treatment regimens or acute illness, the frequency of self-monitoring of blood glucose should be increased (pg 79).

  GPP

• GPP Health care professionals should be familiar with the practical use of glucometers (pg 79).

  GPP

• B To ensure optimal benefit from self-monitoring of blood glucose, patients must be educated on the interpretation of glucose levels (pg 80).

  Grade B, Level 1⁺

• GPP Periodic reviews are recommended to verify users’ competency, together with comparisons between results from patient self-testing of blood glucose in the clinic and simultaneous laboratory testing (pg 80).

  GPP

• GPP It is recommended that calibration checks of meters are periodically conducted using standard solutions according to the manufacturer’s recommendations (pg 80).

  GPP

• D Continuous glucose monitoring (CGM) may be used as a supplemental tool to SMBG in patients with hypoglycaemia unawareness and/or frequent hypoglycaemic episodes (pg 81).

  Grade D, Level 3

• B Self-monitoring of urine glucose is not recommended for monitoring of glycaemic status (pg 81).

  Grade B, Level 1⁺

• A Ketone monitoring should be performed during sustained hyperglycaemia (e.g., blood glucose > 14.0 mmol/l) in patients with type 1 diabetes, especially during acute illness. Blood ketone monitoring is preferable to urine ketone monitoring (pg 81).

  Grade A, Level 1⁺

• D Glycated haemoglobin (HbA_1c) should be performed routinely in all patients with diabetes, at initial assessment and then as part of follow-up care (pg 82).

  Grade D, Level 4

• D The measurement of HbA_1c should be done in laboratories that utilise DCCT-aligned assays (DCCT - Diabetes Control and Complications Trial) (pg 83).

  Grade D, Level 4

• D The following schedule is recommended for HbA_1c testing in patients with diabetes:

  • 3- to 4-monthly in patients with unstable glycaemic control, failure to meet treatment goals, recent adjustment in therapy, or intensive insulin therapy.
  • 6-monthly in patients who have stable glycaemic control and who are meeting treatment goals (pg 83).

  Grade D, Level 4

• B HbA_1c result should be made available at the time that the patient with diabetes is seen (pg 83).

  Grade B, Level 2⁺⁺

• D The targets of glycaemic control should be individualised (pg 83).

  Grade D, Level 4

• GPP Patients should participate in the process of defining their targets of glycaemic control (See Table 6) (pg 84).

  GPP

• A The HbA_1c target for most non-pregnant adults with type 1 or type 2 diabetes should be ≤7.0% or ≤53 mmol/mol (pg 84).

  Grade A, Level 1⁺⁺

• B Lowering HbA_1c target to ≤6.5% or ≤47.5 mmol/mol may be considered for some patients with type 2 diabetes at doctor and patient judgement, if this can be achieved without significant hypoglycaemia. Such patients include those with short duration of diabetes, long life expectancy and no significant cardiovascular disease (pg 85).

  Grade B, Level 1⁺

• D Less stringent HbA_1c target (e.g., 7.0 to 8.5% or 53 mmol/mol to 69.4 mmol/mol) may be adopted for some patients vulnerable to the harmful effects associated with tight glycaemic control. Such patients include those with very long duration of diabetes, known history of severe hypoglycaemia, advanced atherosclerosis and advanced age (pg 85).

  Grade D, Level 4

• GPP Doctors should be vigilant in preventing hypoglycaemia by reviewing treatment regimens in patients with near-normal HbA_1c levels (e.g., <6.0% or 42.1 mmol/mol), especially those treated with insulin or insulin secretagogues (pg 86).

  GPP

Prevention of cardiovascular disease in people with diabetes mellitus

  Grade D, Level 4

• D Patients with diabetes who have overt cardiovascular disease and/or chronic kidney disease but are not on maintenance hemodialysis should have low density lipoprotein (LDL) cholesterol lowered with combination of dietary and pharmacological means to a target of <2.1 mmol/L (pg 96).

  Grade D, Level 4

• D When making a therapeutic decision with the patient, the potential benefits of adding/increasing lipid-lowering pharmacological treatment, needs to be considered together with the potential risks of such treatment (pg 96).

  Grade D, Level 4

• D For most patients with type 2 diabetes mellitus where low density lipoprotein (LDL) cholesterol is >2.6 mmol/L, an HMG CoA reductase inhibitor (statin) should be started concurrently with therapeutic lifestyle modification (pg 97).

  Grade D, Level 4

• D It is reasonable to initiate low dose aspirin for primary prevention in people with diabetes and no previous history of vascular disease at age 50 years for men, and 60 years for women, provided they also have at least one more of the following cardiovascular risk factors: smoking, hypertension, dyslipidaemia, family history of premature cardiovascular disease and albuminuria (pg 99).

  Grade D, Level 4

  Grade A, Level 1⁺

• A In patients with type 2 diabetes, hypertension, and microalbuminuria, angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) are recommended (pg 105).

  Grade A, Level 1⁺

• A In patients with type 2 diabetes, hypertension, macroalbuminuria, and renal insufficiency (serum creatinine >1.5 mg/dl), angiotensin receptor blockers (ARBs) are recommended (pg 105).

  Grade A, Level 1⁺

• D In patients with diabetes, if one class [either angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs)] is not tolerated, the other should be substituted (pg 105).

  Grade D, Level 4

• D When angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs) or diuretics are used, it is recommended to monitor serum creatinine and potassium levels for the development of acute kidney disease and hyperkalemia (pg 106).

  Grade D, Level 4

• A To reduce the risk or slow the progression of nephropathy, optimised lipid control is recommended (pg 106).

  Grade A, Level 1⁺

• A Reduction of protein intake to 0.8–1.0 g per kg body wt per day in individuals with diabetes and earlier stages of chronic kidney disease (CKD) and to 0.8 g per kg body wt per day in the later stages of CKD is recommended to improve measures of renal function (urine albumin excretion rate, GFR) (pg 107).

  Grade A, Level 1⁺

• A It is recommended to consider a low-dose aspirin in diabetic individuals with a history of vascular disease (pg 107).

  Grade A, Level 1⁺

• D It is recommended to consider low-dose aspirin in diabetic individuals who carry significant cardiovascular risk burden (pg 107).

  Grade D, Level 4

• D Continual monitoring of urine albumin excretion to assess both response to therapy and progression of disease is recommended for both type 1 and type 2 diabetes patients (pg 108).

  Grade D, Level 4

• D It is recommended that when estimated GFR (eGFR) is <60 ml.min/1.73 m², evaluate and manage potential complications of Chronic Kidney Disease (CKD) (pg 108).

  Grade D, Level 4

• D It is recommended to consider referral to a physician experienced in the care of kidney disease when there is uncertainty about the etiology of kidney disease (heavy proteinuria, active urine sediment, absence of retinopathy, rapid decline in GFR), difficult management issues, or advanced kidney disease (pg 108).

  Grade D, Level 4

Prevention and management of eye complications

• D All patients diagnosed with diabetes require regular visual acuity assessment and eye examinations by trained personnel to screen for diabetic retinopathy using a test of adequate sensitivity (pg 110).

  Grade D, Level 4

• D Retinal screening preferably using retinal photography or direct ophthalmoscopy (if retinal photography is not available) through dilated pupils is recommended (pg 110).

  Grade D, Level 4

• D Type 1 diabetic patients should have an eye examination 3–5 years after diagnosis of diabetes, and at least once yearly subsequently. Type 2 diabetic patients should have an ocular assessment at the time of diagnosis and at least once yearly subsequently (pg 111).

  Grade D, Level 4

• D Women with diabetes mellitus who intend to have children should preferably have an eye examination prior to conception, followed by one during the early first trimester. Further eye examinations during pregnancy may be done depending on the results of the first trimester examination (pg 111).

  Grade D, Level 4

• A Good glycaemic control (HbA_1c preferably 6.5 to 7.5% or 47.5 to 58.5 mmol/mol) should be instituted to reduce the risk and progression of diabetic retinopathy (pg 113).

  Grade A, Level 1⁺
