Diabetes mellitus

Diabetes is a condition where the amount of glucose in blood is too high because the body cannot use it properly. This is because the pancreas does not produce any insulin, or not enough, to help glucose enter the body’s cells – or the insulin that is produced does not work properly (known as insulin resistance).

There are three main kinds of diabetes: Type 1 diabetes is commonly treated with insulin and often diagnosed in people aged under 30.  Type 2 diabetes can be treated with diet alone, tablets or insulin injections and can be diagnosed at any age, but most commonly from middle-age onwards.  Type 2 diabetes can be associated with being overweight.  Gestational diabetes affects pregnant women and often goes away after birth.  Women who’ve suffered gestational diabetes have an increased risk of going on to develop type 2 diabetes in later life.

Diabetes is a common life-long health condition. There are 2.8 million people diagnosed with diabetes in the UK and an estimated 850,000 people who have the condition but don’t know it.

Health spending on people with diabetes is typically higher than average.  With type 2 diabetes particularly affecting older people, and the number of older people set to rise, having robust plans to meet the future needs of people with this illness is essential.

1. What are the key issues?

  • Increasing prevalence rates will create subsequent increased demand on services
  • Evidence suggests that there are high numbers of people with undiagnosed diabetes.  Undiagnosed diabetes may lead to complications that could be avoided with treatment.
  • High numbers of people identified as having pre-diabetes are progressing to diabetes.
  • Access to self-management education programmes is limited to those newly diagnosed.
  • There is variation in treatment and outcomes at a general practice level.

2. What commissioning priorities are recommended?

2012/01
Further develop, implement and monitor strategies to identify people who do not know they have diabetes.

2012/02
Develop, implement and monitor strategies to reduce the risk of developing type-2 diabetes and to reduce the inequalities in the risk of developing type-2 diabetes.  NICE guidance expected in May 2012 on preventing the progression from pre-diabetes is expected to support this progress.

2012/03
Ensure existing commissioned services are sufficiently resourced to accommodate the increase in the diabetes population.

2012/04
Develop, implement and monitor protocols to further reduce and effectively manage diabetes complications.

2012/05
Provide more life-long opportunities for education and self-management for those with diabetes.

2012/06
Reduce variation by encouraging and promoting peer review among general practices.

3. Who is at risk and why?

Gender
Gestational diabetes is an additional risk factor for women.  Other forms of diabetes are not strongly linked to gender.

Age
Type 1 diabetes is most commonly diagnosed in people aged under 30.  Increasing age raises the risk for developing type 2 diabetes.  Women of child-bearing age, particularly those who are overweight, are at risk of developing gestational diabetes, should they become pregnant.

Ethnicity
It is known that people from South Asian and African-Caribbean ethnic groups are more likely to have diabetes and tend to develop the condition at younger ages.

Socioeconomic status
Diabetes prevalence is higher in areas experiencing deprivation. People living in the 20% most deprived neighbourhoods in England are 56% more likely to have diabetes than those living in the least deprived areas.  This may be due to higher proportions of people in ethnic minorities living in deprived areas, and higher levels of lifestyle risk factors in deprived populations.

Lifestyle
Obesity is the main risk factor for developing type-2 diabetes.  Diabetes is also associated with low levels of physical activity and poor diet and nutrition.

Family history
Those with a family history of diabetes are more likely to develop diabetes themselves.  This may be influenced partly by genetics and partly by social norms.

Risks associated with diabetes
People with diabetes have reduced life expectancy.
Diabetes is a leading cause of cardiovascular disease.
Diabetes is the leading cause of blindness in the working-age population.
Diabetes is the second most common cause of lower limb amputation (trauma being the most common).
Diabetes can impact on mental health and emotional wellbeing ranging from psychological problems dealing with the diagnoses to complex mental illness. The prevalence of depression is twice as high in people with diabetes compared to the general population.

4. What is the level of need in the population?

 Key Points

  • In Redcar & Cleveland the estimated prevalence of diabetes is 7.9%, but only 5.9% of the population has been diagnosed with diabetes.  It is likely that around 2,600 people with diabetes remain undiagnosed.
  • Provision of services in Redcar & Cleveland is in line with England, except for diabetes  education, where levels of diabetes education were about one quarter of the England rate.
  • Redcar & Cleveland spends significantly more than the England average on diabetes care, and has slightly better outcomes.  Prescribing costs are marginally above the England average. While costs in Redcar & Cleveland are high, there is clear scope to improve outcomes.
  • There is variation between general practices within Redcar & Cleveland in terms of identification of people with diabetes, and treatment of those with diabetes.

 

Prevalence of Diabetes

The prevalence of diabetes in Redcar & Cleveland is above the England average.

Crude prevalence rates have increased from 4.6% in 2005/6 to 5.9% in 2009/10.

NHS health checks introduced in October 2008 included checking for diabetes in people aged 40-74 years.

Redcar & Cleveland Diabetes prevalence trend

 

In Redcar & Cleveland, prevalence models suggest that 7.9% of the population (95% confidence interval 5.9%-10.9%) has diabetes (Source APHO Diabetes Prevalence Model).  Current registers of people with diabetes include 5.9% of the adult population, suggesting around 2,600 people have undiagnosed diabetes.  However, this could be as few as zero or as many as 5,200.

Diabetes in General Practices

There is some variation between general practices in identification of people with diabetes.  Six practices in Redcar & Cleveland have identified fewer than 80% of the people expected to have diabetes.  Five practices have identified 100% or more of the people expected to have diabetes.

Diabetes Care

Care process measures for diabetes in Redcar & Cleveland are broadly in line with similar areas.

Redcar & Cleveland diabetes care processes

* Patients may be ‘excepted from measurement’ if they do not attend for review or where there is a clinical contra-indication or side effect.

** Orange Group is one of five groups in the Diabetes Area Classification, which clusters PCTs together that have similar risk factors for diabetes.

A comprehensive range of practice-level indicators is available on the APHO practice profiles website:http://www.apho.org.uk/pracprof

 Redcar & Cleveland diabetes service provision

Additional data show that 92% of diabetic patients received retinal screening (England=91%) and 80% had their blood pressure at 145/85 or less (England=81%). (Source:http://nww.nchod.nhs.uk )

Complications of Diabetes

Emergency admissions for ketoacidosis and coma have been fluctuating around the England average and are generally lower than regional and comparison areas.

Redcar & Cleveland Admission for ketoacidosis and coma

 

Lower limb amputations in Redcar & Cleveland are similar to national rates.  In 2009/10 there were 20 admissions for lower limb amputation (including toe amputations).  There is no obvious trend in amputation rates, but rates have been above England values for the past 3 years.

5. What services are currently provided?

Primary Care
General practitioners continue to provide most of the medical care to people with type 2 diabetes. The complexity of care for this common disease requires systematic care from the practice team and the timely referral to community and hospital-based specialists.   Practices deliver day-to-day care based on locally developed and agreed primary and secondary shared care pathways.  They also ensure they have systems and processes in place to facilitate annual review, usually run by a lead practice nurse.  People diagnosed with diabetes are issued with an information booklet and a handheld record to document agreed goals and an action plan.   Screening for diabetes is provided routinely as part of the Healthy Heart Check CVD screening programme for adults aged 40-74.

Community Care
South of Tees has a diabetes community service which offers a range of multi-disciplinary clinics across the South Tees area.  The multi-disciplinary team providing this service include diabetes specialist nurses, doctors with a special interest in diabetes, dieticians and podiatrists.
The diabetes community service provides clinical management of complex diabetes needs, including insulin initiation and titration in type 2 diabetes and initiation of new treatments. The specialist team also deliver structured education for those newly diagnosed with type 2 diabetes (DESMOND), empowering the person to take responsibility for the management of his or her own condition.
The South Tees area has an established diabetes retinal screening programme (DRSS) delivered by James Cook University Hospital from community locations across Middlesbrough and Redcar & Cleveland.
There is a voluntary support group for all people with diabetes living in Stockton-on-Tees.  The group meets on a monthly basis to give and receive support and share experiences with both the newly diagnosed and the more experienced person with diabetes.  The group is affiliated to Diabetes UK, the national charity supporting people with diabetes.

Secondary Care
Specialist care diabetes services are delivered by the South Tees Foundation Trust at two sites: Friarage Hospital, Northallerton and James Cook University Hospital, Middlesbrough.
Consultants manage those people who have developed significant complications from their diabetes as well as any acute or planned admissions for adults and children.  There are specialist clinics for:

  • Pregnant women and those planning a pregnancy
  • Adolescents and young adults
  • Patients treated with insulin pump therapy
  • Patients with diabetic renal disease
  • Patients with diabetic foot disorders
  • Patients with increased cardiovascular risk.

The specialist team also deliver DAFNE structured education programme for those adults with type 1 diabetes.  This programme aims to provide participants with the skills of carbohydrate counting and insulin dose adjustment.

Map of Medicine
Full details of all local services and clinical guidelines are available on the Tees Map of Medicine website.  This is only available to healthcare professionals.

6. What is the projected level of need?

Diabetes prevalence is forecast to rise.  This is due to factors such as people living longer, an increase in the proportion of people aged over 50 and the rise of obesity as a major risk factor for diabetes.

The chart below shows forecast rates of diabetes for the next 20 years.  Although the confidence interval is wide, there is a clear rise expected in diabetes rates.  In 2010 it is estimated that nearly 9,000 people in Redcar & Cleveland have diabetes (we only know about 5,500 of these).  This will rise to 10,600 by 2020 and up again to 12,100 in 2030.  Diabetes care services will need to plan to cater for this expected rise in need.

7. What needs might be unmet?

Self-management is recognised as the cornerstone of diabetes care but currently there is no routine, ongoing assessment of educational need.  Structured education programmes limited to those newly diagnosed.

People at risk of developing diabetes are not being systematically identified. When they are, many people still continue to progress to develop diabetes.

Despite the introduction of systematic review for patients, diabetes complications rates remain high.

9. What do people say?

Diabetes Survey: 2010

Patients & Carers

A survey targeted at the diabetes population was distributed through the diabetes community and secondary care clinics, the retinal screening service and Diabetes UK throughout August 2010. 

Overall the results around access, choice and support for diabetes patients were very positive.  DESMOND education in particular received a lot of positive comments and people stated they would like further access to ongoing DESMOND education at regular intervals.

A report of the survey was produced and is available at:
