You can create your own water-based solution by pouring boiling water over cinnamon in a coffee filter either with or without coffee grounds. If you gestational diabees and atkins diet how mellitus test for urine have low blood sugar you may have these symptoms: Shakiness or dizziness. All of these components have been demonstrated in scientific studies to provide benefits for diabetes and fat loss. Every patient with documented type 2 diabetes mellitus (T2DM) should have a comprehensive care plan (CCP), which takes into account the patient’s unique medical history, behaviors and risk factors, ethnocultural background, and environment.
The multidisciplinary team typically oversees the medical management of T2DM, including the prescription of antihyperglycemic therapy and the delivery of diabetes self-management education (DSME). Either the physician or a registered dietitian (RD) should discuss healthful eating recommendations in plain language at diagnosis of T2DM and then periodically during follow-up office visits (Table 1).
MNT involves a more detailed discussion of calories, grams, and other metrics, as well as intensive implementation of dietary recommendations aimed at optimizing glycemic control and reducing the risk for complications.
Patients should be advised that any physical activity is better than none, and that they should make every effort to increase their activity level. An exercise prescription should be developed for each patient according to both goals and limitations.
Antidiabetic treatment should be promptly intensified to maintain blood glucose at individual targets. Selection of agents should be based on individual patient medical history, behaviors, and risk factors, ethnocultural background, and environment.
Self-monitoring of blood glucose (SMBG) is a vital tool for day-to-day management of blood sugar in all patients using insulin and many patients not using insulin.
Most patients with an initial A1C level greater than 7.5% will require combination therapy using agents with complementary mechanisms of action. Antihyperglycemic agents may be broadly categorized by whether they predominantly target FPG or PPG levels (see Table 3). The choice of whether to target FPG or PPG should be based primarily on the individual patient’s glycemic profile obtained by self-monitoring of blood glucose (SMBG).
Intensification of pharmacotherapy requires glucose monitoring and medication adjustment at appropriate intervals when treatment goals are not achieved or maintained.
Long-acting basal insulin is generally the initial insulin choice, and the insulin analogues glargine and detemir are strongly preferred over human NPH insulin because they have relatively peakless time-action curves and a more consistent effect from day to day, resulting in a lower risk of hypoglycemia.
Basal insulin is usually added to existing noninsulin therapy, and many antihyperglycemic agents are approved for use with insulin: DPP-4 inhibitors, glinides, GLP-1 receptor agonists (but not exenatide XR), metformin, pramlintide, sulfonylureas, and TZDs. The risk of hypoglycemia is increased when combining insulin with sulfonylureas, glinides, DPP-4 inhibitors, and GLP-1 receptor analogues. GLP-1 receptor analogues and DPP-4 inhibitors have not been studied with prandial insulin. Using insulin with TZDs may increase the risk of weight gain, edema, and congestive heart failure. Rapid-acting insulin analogues are preferred over regular human insulin because they have a more rapid onset and offset of action and are associated with less hypoglycemia.
Premixed insulin analogue therapy may be considered for patients in whom drug regimen adherence is an issue; however, these preparations lack component dosage flexibility and may increase the risk for hypoglycemia compared with basal insulin or basal-bolus insulin. This approach (ie, transitioning to insulin after noninsulin agents fail to maintain glycemic targets) is supported by the recently published results of the Outcome Reduction with an Initial Glargine Intervention (ORIGIN) trial. Several new classes of agents are under investigation for the treatment of T2DM, and some new agents within existing classes may represent improvements over currently available options.17 The listing in Table 4 should be considered representative and not necessarily all-inclusive. For complete descriptions of the devices and accompanying technology themselves, click on the links above. CSII is recommended mainly for patients with type 1 diabetes mellitus (T1DM), but patients with advanced T2DM who are absolutely insulin-deficient, take 4 or more insulin injections a day, and assess their blood glucose levels 4 or more times daily are candidates for CSII. Safety—particularly the risk of hypoglycemia—should be the primary concern when choosing an antidiabetic therapy.
Table 3 lists the major safety risks associated with currently available antidiabetic agents. Severe hypoglycemia stimulates sympathetic adrenergic discharge, causing arrhythmias or autonomic dysfunction (or both) and has long been recognized to have potential for causing mortality. In addition to increased mortality, hypoglycemia negatively affects adherence to therapy and quality of life and also contributes to morbidity.
Management of hypoglycemia involves appropriate choice of antihyperglycemic therapy, tailoring of insulin treatment to minimize risks, and patient education in the recognition and treatment of acute hypoglycemia (Table 5).40 It is important to remember that the features listed in Table 5 occur along a continuum, and glycemic thresholds and symptom manifestations may vary widely among individuals. For T2DM patients, most of whom are overweight or obese, the risk of additional weight gain must be balanced against the benefits of the agent itself. Once T1DM and monogenic diabetes have been ruled out and a T2DM diagnosis has been definitively established for a child or adolescent, diet and lifestyle modification are always the first treatment choices.
Children born to women with any form of diabetes are at greater risk of developing T2DM themselves.
Older adults are more likely to have an increased number of comorbid conditions (eg, frailty, dementia, depression, urinary incontinence) that can complicate their diabetes management. Fasting is a common religious practice that can pose a challenge to diabetes management, particularly if the fast occurs over an extended time, such as Ramadan, a holy month of Islam in which all healthy adults consume no food or fluids between sunrise and sunset. The risk of these outcomes depends on the severity and complications of T2DM according to the categories in Table 7.
For the management of glycemia during extended fasts, general principles and recommendations are listed below. In general, weight loss can be achieved using a balanced diet that neither avoids nor focuses heavily on one food group.

Many people with type 2 diabetes mellitus spend a lot of time, effort and money trying to keep their blood glucose down to normal or close to normal. The Canadian Guidelines posted on the Canadian Diabetes Association website were accessed to find out what evidence is available to answer this question.1 The Guidelines combine recommendations for type 1 and type 2 diabetes, but for this Letter references and information pertinent to type 1 diabetes have been removed. The guidelines caution that these targets must be individualized and will not be appropriate for all patients. Grade A, Level 1A means that it is based upon a systematic review of high quality randomized controlled trials or an appropriately designed randomized controlled trial with adequate power to answer the question posed by the investigators.
Prior to February 2008 there was no evidence to support these assumptions and since February 2008 there is evidence which places these assumptions in doubt.
Additional RCTs that test specific glycemic targets are needed for the full spectrum of patients with type 2 diabetes.
The draft of this Therapeutics Letter was submitted for review to 40 experts and primary care physicians in order to correct any inaccuracies and to ensure that the information is concise and relevant to clinicians.

These recommendations are suitable for the general population, including people without diabetes, and focus on foods that can promote health vs foods that may promote disease or complications from disease. Recommendations should be personalized, and in general, evaluation and teaching should be conducted by an RD or knowledgeable physician. Overweight individuals with type 2 diabetes should strive for a 5% to 10% reduction in weight and should avoid weight gain.

In fact, foot complications are the most common reason for diabetics to be hospitalized each year. It covers more than the standard foot exam that non-diabetics would have, so you’ll need to go to a board-certified podiatrist to have the job done.
Assessment of Diabetic Foot Complications – The doctor will find out whether you suffer from peripheral neuropathy, cardiovascular disease, nephropathy, or another coexisting medical issue.
Current History – Recent history of ulcers, pain in the calves, hemoglobin test results, shoe problems, and bleeding incidents are also discussed. Foot Exam – During the foot inspection portion, the doctor will look at the condition of the skin to see if it is thin, fragile or shiny. Footwear Assessment – The doctor will look to see that you are wearing appropriate shoes and discuss inserts or the prescription of special footwear, if necessary. Screening for Type 2 DiabetesType 2 Diabetes may well be a suitable disease for screening - it is a serious disease, being associated with many complications, especially in the eyes, heart, kidneys, and limbs and it shortens the expectation of life considerably. As one might expect, receiving a ‘positive’ result after the screening test can also cause negative emotional reactions. A meta-regression analysis of published data from 20 studies of 95,783 individuals followed for 12.4 years. Recommendations should be personalized on the basis of a patient’s specific medical conditions, lifestyle, and behavior. To date, metformin remains the only oral medication approved by the FDA for use in children with T2DM. Patients with kidney disease (especially patients on dialysis) face many emotional and social stressors. The guidelines imply that these targets will reduce complications associated with diabetes and that the benefit of this approach outweighs the harm.
The patients randomized to the intensive glycemic group will be treated to the higher glycemic target for the remainder of the trial.

He will look at the condition of the nails to see if they are too long, ingrown, or yellowed with toenail fungus. On the other hand, the presence of any warning signs may put a person into a higher risk category. Other times, you may be referred to another specialist or required to have tests conducted on abnormal tissue. Bryan Markinson has served as the Chief of Podiatric Medicine and Surgery at Mount Sinai School of Medicine since 1999. Diagnosing Type 2 diabetes before patients complain of diabetic symptoms – clinical opportunistic screening in a single general practice.
It is a condition associated with numerous complications, which may well be present even at the time of diagnosis. Guidance (American Diabetes Association, 2011; Diabetes UK, 2006) exists for health professionals with regard to the interpretation of test results. People are not always reassured, even by a ‘normal’ result, and other adverse psychological effects can occur.

Patients unable to maintain a healthy weight on their own should be referred to an RD or weight-loss program that has a proven success rate. Insulin use in the prediabetic patients did reduce the incidence of T2DM (see detailed discussion in Prediabetes), but there was no difference in cardiovascular outcomes between treatment groups after 6 years. For me, there is no greater happiness than partnering with these patients in their health and emotional content.
The targets create serious challenges for physicians and patients, which have significant implications in terms of time, effort and utilization of health care resources. This reduction is entirely explained by the reduction of one of the microvascular endpoints, the need for retinal photocoagulation, ARR 2.7%. We developed the SteriShoe UV shoe sanitizer to be part of a self-care regimen for diabetics to help keep people out of the hospital. He’ll look for calluses, ulcers, pre-ulcers, fissures, swelling, warmth, redness, and dryness. For example, a ‘normal’ result may reinforce an unhealthy lifestyle or perceptions of invulnerability, and make patients less likely to return for future screening (Marteau 1989).

Andrew Shapiro has been a board-certified podiatrist operating in Valley Stream, New York since 1987.
The focus therefore is on both prevention and early detection by screening, with a view to preventing or delaying complications. Blood glucose tests and oral glucose tolerance tests have no adverse effects for the patient apart from the inconvenience of having blood tests and the very rare complications of venepuncture.There are two broad approaches to screening for Type 2 Diabetes – population or opportunistic screening.
Recently, studies in Europe and the USA have specifically explored the psychological effects of undergoing screening for Type 2 Diabetes and these tend to support the conclusions of Marteau’s work. With over 550 recipes this trio of quick & easy meals for The immediate treatment of hypoglycaemia is to have some sugary food or drink such as You may be given a concentrated glucose drink to keep on hand in case you have hypoglycaemia.

Like her non-diabetic counterpart a pregnant woman with gestational diabetes is best food to eat for diabetes encouraged to remain physically active.
This chapter gives a brief overview of the evidence for prevention of Type 2 Diabetes (behavioural and pharmacological) and describes various approaches to screening, from an international perspective, together with their relative advantages and disadvantages. Approaches to screeningA number of targeted screening programmes have been piloted in the UK, Europe and the USA in the last decade (e.g.
Next, he will test sensitivity by running a thin nylon filament across the bottom of the foot to see if you can feel it. Such studies have generally found no lasting or significant adverse psychological effects in terms of anxiety, depression, worry, or perceived quality of life after screening. Katarina, online jewelry stores provide exquisite collection of diamond, gold, pearl, silver rings, bands, bracelets, earrings, and cufflinks for anniversary, engagement and wedding.
The international guidance for screening for Type 2 Diabetes will be reviewed and a summary of the evidence relating to the psychological effects of screening, as well as the costs and cost-effectiveness of the various types of screening programmes, will be presented.2. Population screeningPopulation screening, as its name implies, is based on a defined population and aims to screen every person in this population (Engelgau et al., 2000). Many have employed a ‘stepwise’ approach, whereby participants progress through increasingly invasive screening procedures until they are diagnosed with diabetes or found not to have the condition. The rationale for preventing Type 2 Diabetes and its complicationsThe prevalence of diabetes, particularly Type 2 Diabetes, is increasing on a worldwide scale. One study, which interviewed people shortly after they underwent screening tests (Adriaanse et al., 2002), found most participants had positive views of the screening process and had not found it burdensome.
In either case, a suitable test such as a screening blood glucose test is offered to a defined population. Most individuals who had been newly-diagnosed with diabetes did not feel alarmed or concerned about their results. Your eye care professional can tell if you have macular edema or any stage of diabetic retinopathy.
Many appeared to believe they had a ‘mild’ version of the condition that they could control, although they felt the required lifestyle changes would have a significant impact on their life.
For example between 10% and 20% of patients aged 60 to 79 years in the European prevalence study (DECODE) had diabetes (DECODE Study Group, 2003). However, the yield was small as many people at low risk were approached and some of those detected failed to consult their GP. A recent alternative approach has been the use of online self-completion risk tools to determine a person’s risk of diabetes and hence the need for further action.
People whose test results were normal reported feelings of relief or reassurance but saw no reason to change their lifestyle. It has been estimated that having diabetes reduces life expectancy by 17 years in males and 20 years in females, who are diagnosed with the condition at the age of 45 years (Yorkshire & Humber Public Health Observatory, 2007). Community screening could be cost-effective if the prevalence of Type 2 Diabetes in the community was extremely high, although this is rarely the case.
It is also generally acknowledged that a large number of patients with Type 2 Diabetes remain undiagnosed.
The populations most often identified for screening include people selected because they have one or more risk factors for Type 2 Diabetes. If the results of the initial blood test fall within the normal range, the participant does not progress to the next level, but may receive lifestyle advice.
These most commonly include older age, obesity, a family history of diabetes, and hypertension. If the results of the initial test reveal glucose levels above a specified threshold, participants are invited back for further testing.
This approach increases the likelihood of finding new cases and so improves the efficiency of the screening process.Risk factors are most commonly known to GPs. At that stage, the screening test may require the patient to fast for a prescribed period prior to the blood sample or undergo a more complex and lengthy screening process, such as the oral glucose tolerance test.Uptake of screening has varied across the studies and this may be a reflection of the type of test offered, how the invitation is made and where the testing takes place. The economic cost of screening for Type 2 DiabetesEconomic modelling studies have been conducted to estimate the cost-effectiveness of screening for Type 2 Diabetes and Impaired Glucose Tolerance.
They are not known to hospitals, as they do not hold the medical records of populations, only those people referred to them.
In one study (O’Connor et al., 2001), the uptake of an initial random blood glucose test (offered via letter) was 44%. In the UK, decisions about funding of interventions are made by the National Institute for Health and Clinical Excellence (NICE), based on cost-effectiveness. Patients who eventually develop Type 2 Diabetes often pass through a phase of intermediate hyperglycaemia when their blood glucose levels are elevated but not above the diagnostic threshold for Type 2 Diabetes. Hence, population screening nowadays is most commonly based on people selected from the population registers of people registered with family practices. Where random capillary blood tests were offered, however, uptake was around 60-70% (Echouffo-Tcheugui et al., 2009).
This body considers that interventions below an incremental cost-effectiveness ratio (ICER) threshold of ?20,000 to ?30,000 per quality-adjusted life-year (QALY) are cost-effective (National Institute for Health and Clinical Excellence, 2004).
These intermediate states are collectively called Prediabetes and include Impaired Fasting Glucose diagnosed on a fasting plasma glucose test or Impaired Glucose Tolerance diagnosed on an oral glucose tolerance test. This has meant that most of the research reports have come from those countries in which the health system is based on family practices, i.e. In one study, the reported uptake of a fasting capillary blood glucose test offered directly by the GP was 90% (Woolthuis et al., 2009). One systematic review and economic modelling exercise (Waugh et al., 2007), which included four studies, reached the conclusion that screening for diabetes appeared to be cost-effective for people aged 40-70 years. Australia, Canada, New Zealand, the Netherlands, the UK, Denmark, and registration-based systems in the USA.Population screening has several important advantages.
Whilst screening was more cost-effective for the older age bands (50-69 and 60-69 years), even for people aged 40-49 years, the ICER for screening (when compared to a policy of not screening) was ?10,216 per QALY. Prediabetes carries an increased risk of progression to Type 2 Diabetes although this can vary widely, dependent on ethnicity and other factors (Unwin et al., 2002). It is mathematically precise, readily reproducible, and can operate largely independent of the clinical skills of the doctors and nurses in the family practices.
Screening was found to be more cost-effective for people who were hypertensive and obese and, for many groups, the costs of screening were offset by lower treatment costs in the future. It is easy to transpose arrangements across areas and countries.Population screening has several important disadvantages.
The St Leonard’s Practice approach to screening for Type 2 DiabetesThe system of screening for Type 2 Diabetes in the St Leonard’s Practice, Exeter, UK is one special form of clinical opportunistic screening (Evans et al., 2008).
Unless whole community populations are used, various techniques have to be employed to determine potential sub-groups at risk. When comparing a policy of not screening to one of screening for Type 2 Diabetes and Impaired Glucose Tolerance, there were differential costs for each QALY gained, depending on whether diagnosis of Impaired Glucose Tolerance was followed by lifestyle interventions or by pharmaceutical interventions.
The process relies on the clinical alertness of the GPs and practice nurses, and the efficient protocol-driven screening of patients with chronic conditions known to be associated with Type 2 Diabetes. The costs per QALY gained were ?6,242 for screening followed by lifestyle interventions, and ?7,023 for screening followed by pharmacological interventions. The doctors and nurses screen adult patients with cardiovascular or cerebrovascular disease, hypertension, hypercholesterolaemia, obesity, recurrent skin infections, or a positive family history of diabetes. In contrast, the cost-effectiveness of a policy of screening for Type 2 Diabetes only was less certain.
In the Finnish Diabetes Prevention Study, this was achieved by offering detailed and individualised counselling to achieve set lifestyle goals. However, there are always people, including those at risk, who decline to accept the offer of screening for a variety of reasons.

Its advantages are that it eliminates another layer of costs that arise from the involvement of an external agency, such as a university or medical school.
Here, compared to a policy of not screening, the estimated costs for each QALY gained in respect of screening for Type 2 Diabetes alone were ?14,150. Prolonged engagement with a dietary counsellor was needed – for example, the median number of sessions per participant was 20 (Tuomilehto et al., 2001). The process then involves communication with the people in the target population, usually by writing to them and offering them an appointment.
It also means that people from external organisations do not see confidential medical records.
The results of the above studies suggest that it may be more cost-effective to screen for Type 2 Diabetes and Prediabetes, rather than Type 2 Diabetes alone. Some people will want to change their appointment and staff of the practice need to accommodate this. A recent meta-analysis has shown that lifestyle interventions can produce a 50% relative risk reduction in the incidence of Type 2 Diabetes at one year (Yamaoka & Tango, 2005).
In one US study (O’Connor et al., 2001), which used a two-step screening protocol (random blood glucose followed by oral glucose tolerance test), one new case of diabetes was identified for every 40 high-risk patients screened. It is possible to maintain the system year after year and it has been so maintained in this practice since 1987 (Evans et al., 2008).
The uptake of screening was relatively low (44% of patients who were invited attended) and the screening costs per new case were estimated at $4,064 per new case identified. We subsequently developed an educational package for patients with Prediabetes and their healthcare professionals. Then, if the screening process is separate from the clinician, the clinician has to be informed and take action.
Clinical opportunistic screening has the advantage that, since so many blood tests are taken nowadays in family practice, it is often possible to add the blood glucose screening test to samples being taken already, thus saving the patient an additional blood test. More recently, a Danish study (Dalsgaard et al., 2010) has compared three different stepwise screening strategies for Type 2 Diabetes.
In some US studies, primary care clinicians have not always responded appropriately (Ealovega et al., 2004). In the first strategy, diabetes risk questionnaires were sent by the family practice to people aged 40-69 years and those found to be at high risk were asked to contact their GP to arrange a screening test. It is generally acknowledged that the intensity of the lifestyle intervention delivered in these trials is just not feasible in routine practice (Heneghan et al., 2006).
There may be a difference in attitude to those tests initiated by clinicians themselves and those tests initiated by others. This strategy detected new cases of Type 2 Diabetes in 0.8% of the target population, at a cost of €1,058 (US$1,535)” per case. It is inevitable that population screening carries administrative costs over and above the cost of the screening investigations.
Its main advantage internationally is that the method is more easily reproducible in family practices around the world.
Nevertheless, in the UK, the National Health Service has recently instituted a comprehensive vascular risk assessment programme, known as ‘NHS Health Checks’ (Department of Health, 2008). All that is needed is an enthusiastic family practitioner or nurse and an efficient computerised medical record system.
In these approaches, people who were consulting their GP were asked to complete the risk questionnaire in the waiting room and were either offered a screening test during the consultation (OP-direct) or asked to return for a fasting screening test at a subsequent consultation (OP-subsequent). Prevention of the complications of Type 2 DiabetesOnce a patient has developed Type 2 Diabetes, the major aim of clinical care is to prevent complications and morbidity related to the disease.
These checks are offered to patients aged 40 to 74 years old who do not have existing vascular disease or diabetes. The commonest complication of Type 2 Diabetes is cardiovascular disease (American Diabetes Association, 2011) manifested as coronary artery disease, peripheral vascular disease or carotid artery and other cerebrovascular diseases.
This is a two-step process and diabetes risk is estimated using a self-completed questionnaire, followed by a blood test if appropriate. The disadvantages of the St Leonard’s system are that the intervention is not standardised and that there are variations between the six doctor partners operating it.
The authors concluded that opportunistic screening can identify a similar proportion of new cases as mail-distributed questionnaires, but at lower cost.5. It is generally acknowledged that patients with Type 2 Diabetes have a raised cardiovascular risk and this may well be present before a clinical diagnosis is made (Hu et al., 2002).
It is envisaged that the whole of this age group in the population will be screened once every five years.
It is not yet known how easy it will be to roll it out into other family practices more widely and it may be difficult where morale is low or burnout amongst the doctors is a serious problem (Soler et al., 2008). ConclusionsThe worldwide epidemic of diabetes, mainly Type 2 Diabetes, calls for a major response as, in some countries, prevalence now exceeds 10% of the whole adult population.
Some studies have shown that this risk is equivalent to that of a patient of the same age who does not have diabetes but has already had a coronary event (Haffner et al., 1998).
Clinicians are seeking to prevent the condition developing and to screen for undiagnosed cases. Hence, Type 2 Diabetes is often termed a “coronary risk equivalent“, although this has been contradicted recently in a systematic review and meta-analysis (Bulugahapitiya et al., 2009). Hence, one profound implication is that population screening may well be too costly to be undertaken in developing countries and this is doubly serious as many Asian countries have some of the highest levels of prevalence of Type 2 Diabetes in the world, e.g. Since Type 2 Diabetes is increasingly managed in family practice or primary care, education and support is important.Prevention of Type 2 Diabetes is now possible through lifestyle alteration but, so far, only after expensive interventions.
However, what has yet to be definitively established with regard to screening is whether early diagnosis reduces the risk of complications developing. Clinical opportunistic screeningClinical opportunistic screening is quite different from population screening and is a form of clinical case finding. Once Type 2 Diabetes is diagnosed, health professionals can then intervene as early as possible, before symptoms develop, in order to prevent complications.
Effectiveness of treatment of Type 2 DiabetesEffective treatments for the disease are available through lifestyle advice, oral hypoglycaemic drugs, and insulin.
The key difference from population screening is that the patient, rather than the clinician, makes the appointment. Population screening is likely to be introduced in richer countries and has recently started in the UK.
In clinical opportunistic screening, the patient makes the appointment to go to the family practice and then the clinically alert doctor or nurse takes advantage of the patient’s presence in the consulting room to offer screening, based on their risk factor profile.
Clinical opportunistic screening in family practice offers an important alternative approach since it may well be more cost-effective, provides the quickest route to treatment, and can detect two-thirds of all new cases of Type 2 Diabetes in a defined population. This process has a long tradition in family practice and the whole basis of determining how many people smoke, drink heavily, are overweight or obese, or have raised cholesterol levels has been done in family practices without any national screening programmes. However, the effectiveness of this type of screening in routine care without extra resources has only been demonstrated in one practice and needs replication. As yet, there are no long-term studies of the effectiveness of treatment after diagnosis of Type 2 Diabetes in screened and unscreened groups, so health economic simulations are needed - with their accompanying assumptions.These models use data from the UK Prospective Diabetes Study (UKPDS, 1998) which showed that intensive treatment of Type 2 Diabetes reduced the risks of microvascular complications but not macrovascular events.
Since more clinical conditions are screened for opportunistically than are screened for by formal population programmes, opportunistic screening can be seen as the usual method of screening. If the early reports are confirmed, then clinical opportunistic screening warrants further consideration as an affordable alternative to population screening, particularly in the developing world.
However, subsequent follow up after the trial had finished did show a reduction in macrovascular events in the intensive arm (Holman et al., 2008). National guidance for the effective treatment of Type 2 Diabetes in primary and secondary care exists in the UK (National Collaborating Centre for Chronic Conditions, 2008; National Institute for Health and Clinical Excellence, 2009) and in the US (American Diabetes Association, 2011). The introduction of computer systems in UK family practices (since the 1980s) has enabled generalist doctors and nurses – for the first time – to organise, handle, and retrieve data live during consultations. AcknowledgementsWe acknowledge with thanks the assistance of Ms Beverley Berry, Information Manager at the Royal College of General Practitioners, London, who provided references for reports relating to early community screening programmes in Rotherham, Bedford and Birmingham. These guidelines are evidence-based and should improve outcomes in patients with Type 2 Diabetes. Computers have made the family practice consultation much more efficient and opportunistic screening is one aspect of this.Clinical opportunistic screening has several advantages. Effective treatments are targeted at optimising cardiovascular risk factors, including serum lipids, HbA1c and blood pressure.
Firstly, this process eliminates most of the costly administrative overheads associated with population screening. In addition, GPs in the UK also receive incentivised payments under the Quality and Outcome Framework when patients with Type 2 Diabetes reach the glycaemic, blood pressure and lipid targets (Roland, 2004).3. Secondly, since the offer of screening is made within a therapeutic and trusting patient-doctor relationship, acceptance rates are generally high.
An important advantage is that the screening process is offered by the doctor who will care for the patient if the disease is diagnosed, so that, if the test is positive, treatment can start immediately. An examination or a test is offered to asymptomatic people “to classify them as likely or unlikely to have the disease that is the object of screening” (Morrison, 1998). Thirdly, the relatively high contact rate that people have with their primary health care team underpins clinical opportunistic screening. People who are likely to have the disease are then investigated further to arrive at the final diagnosis.
An early diagnosis and treatment activity applied in large groups is often described as ‘mass screening’ or ‘population screening’ (Morrison, 1998). For example, GPs are spending more and more of their time seeking to alter risk factors for disease.
Population screening in medicine was introduced in the mid-twentieth century and was applied to a number of diseases including tuberculosis, and more recently to cervical cancer, breast cancer and colon cancer. They screen for and increasingly find and then treat hypertension, itself a risk factor for Type 2 Diabetes and also for obesity which is all too obvious to the clinician. It was also attempted for diabetes.There are two inevitable consequences of all screening programmes, namely the occurrence of what are called ‘false positive’ or ‘false negative’ results. Other risk factors such as a positive family history may be very well known too as the family doctor will have often treated the older family members for diabetes and may still be doing so.
False positives are people whose test is positive for the disease being sought but who prove not to have the disease. Fifthly, this is the only system which can be undertaken in developing countries and is possible wherever there are generalist doctors.
People classified as false negative are those who actually have the disease but the test fails to detect it. Realistically, it cannot be expected to cover the entire at-risk population and it is dependent on the patient consulting for some reason. Evaluation of screening programmesBefore any screening programme is introduced, its advantages and disadvantages must be carefully assessed. The general principles of screening were initially set out in the late 1960s (Wilson & Jungner, 1968). This is not standard, and there are inevitable variations in clinical skills, which means variations in the screening process being delivered. Since then, the criteria have been updated (UK National Screening Committee, 1998) and programmes now need to meet a number of criteria. The offer of clinical opportunistic screening is a judgement and different clinicians will make different judgements at different times. These broadly relate to the health condition, the screening test, the availability of effective treatment, and the screening programme itself. Figure 2 outlines our summary of the criteria currently used by a variety of international health organisations to evaluate population screening. Hence, they have been criticised by some as inefficient (Law, 1994) and can be seen as untidy, and potentially unpredictable. Whilst Type 2 Diabetes meets many of the criteria for screening, the main argument against population-based screening is that uncertainty remains about the true benefits arising from the early detection of Type 2 Diabetes through such programmes.
International guidelines on screening for Type 2 DiabetesWhilst there is not yet sufficient evidence to support the introduction of general population screening, there is broad support for screening programmes that focus on defined sub-groups of the population who are at higher risk of developing Type 2 Diabetes. A number of organisations have issued position statements relating to targeted or opportunistic screening for Type 2 Diabetes (e.g. Who should be offered screening and how frequently?It is generally accepted (American Diabetes Association, 2011; Diabetes UK, 2006) that clinical judgement and patient preference should guide decisions about screening for Type 2 Diabetes. However, Diabetes UK (2006) and the American Diabetes Association (2011) recommend that health professionals should consider proactively screening adults at risk of developing the condition every three years. Where should screening take place?Currently, the consensus view is that screening should take place in a clinical setting, with testing offered by health care providers, based on an assessment of the individual patient.
Diabetes UK (2006) supports community screening for patient groups who do not routinely access family practice services, provided that the screening process is guided by clear protocols, staff receive appropriate training, and good medical support is available from local health services. In contrast, the American Diabetes Association (2011) does not recommend community screening, even for high-risk populations, because there is a risk that those screened may not seek or be able to access appropriate follow-up and care.
Which screening test should be used?There is insufficient evidence to identify a single ideal screening test (Waugh et al., 2007). A range of tests exist which might be used for screening purposes and these vary in their sensitivity and specificity, as well as their convenience, acceptability and cost (Cox & Edelman, 2009). It is easier and faster to perform in clinical settings, more convenient and acceptable to patients, and less expensive than other tests.
The latest US guidance (American Diabetes Association, 2011) also states that the HbA1c and 2-hour 75g oral glucose tolerance test are appropriate tests to screen for diabetes. European guidance has tended to encourage the use of the oral glucose tolerance test as the gold standard diagnostic test (Waugh et al., 2007).
