Recent developments in the local diabetes services

 

Key points

 

 

  • Prosiect Sir Gâr:  Workplace cardiovascular health checks for those over the age of 40 began in September 2009, with over 300 checks performed in the first 3 months on employees of Corus Steelworks and Hywel Dda Heath Board.

 

  • The Swansea Masters level module in Diabetes takes the form of  5 teaching days at monthly intervals, with an MCQ test, an audit project and a 2,000 word long case at the end. Five courses involving 70 participants have been held so far, including one held in the St David’s Education Centre in Carmarthen.

 

  • The Community Diabetes Nurse Specialists, along with the dietitian, continue to deliver the XPERT structured education course for people with type 2 diabetes. From 2006-2009, 18 courses have been completed by 237 participants. 

 

  • The multidisciplinary foot clinic at WWGH will help to identify potentially limb threatening foot problems at an early stage, enabling preventive measures to be adopted.

 

  • The Carmarthenshire Chronic Conditions Collaboration  is a demonstrator site for chronic disease management in Wales and promises to have a major influence on how these services are delivered in the future.

 

  • The number of clinical contacts made by members of the PPH and WWGH diabetes team in various settings during 2009 was 17,996. Audit of electronic records for the 1,418 patients followed up in the Trust’s outpatient clinics show a further  improvement in the completeness of the clinical record. Mean duration of diabetes was 22 years for Type 1 patients and 15 years for Type 2 patients. Cardiovascular risk factor mean values in these patients with advanced diabetes were: HbA1c 8.4%, blood pressure 136/72 and cholesterol 4.2, respectively.

 

 New clinical developments

 

A pilot Diabetic nephropathy clinic has commenced in WWGH

A pilot Specialist Weight Management Clinic, based on the Blaenau Gwent model has commenced in Carmarthenshire, incorporating medical, psychological and dietetic treatment. 

Continuous blood glucose monitoring equipment is now available to investigate those patients with erratic glycaemia, particularly those with difficult hypoglycaemia problems.

We have now been using GLP-1 agonists for over 12 months. They are particularly useful for those people with type 2 diabetes who require insulin in whom there is a major concern about potential weight gain. Our data on the first 10 patients showed an average reduction in HbA1c by 0.8% whilst achieving average weight reduction of 7.6kg after 6 months’ treatment.

 

Multidisciplinary high risk foot clinic

Amputation in diabetic foot disease, which is related to almost 75% five year mortality, has been reduced significantly in those centres running a high risk multidisciplinary foot clinic. This fortnightly clinic held at WWGH is now into its third year. The aim of this clinic is firstly, to manage the foot problem using a multidisciplinary approach and secondly, to identify and manage any other complications or inadequately controlled risk factors. We have established a referral system from primary and secondary care podiatry. A range of Diabetic foot complications are seen in the clinic, ranging from Charcot neuroarthropathy, osteomyelitis, peripheral vascular disease and related ulceration etc. So far we have achieved significant success in ulcer healing and reduction of the amputation rate. After the completion of treatment patients are referred back to community podiatry for long term follow up. We are planning a further audit of diabetic foot amputations during 2010.

 

 

Vector Diabetes Electronic Patient Record

 

We now have detailed clinical information on 8,275 people with diabetes. The annual number of patient contact entries by diabetes nurses and doctors in 2009 was 17,996. This enables excellent communication between members of the diabetes team and also with patients, their carers and primary care staff. As the electronic record is used by the whole multidisciplinary diabetes team, we often look at each other’s entries and this provides a powerful safeguard against errors that could cause harm. Since the EPR system enables us to aggregate large amounts of data, we can get an accurate assessment of many clinical and laboratory data which reflect upon the quality of the service (see below). 

The link to the Telepath system allows automatic transfer of patients’ pre-clinic test results to the EPR, making the clinical process more efficient.

 

 

Shared Diabetes Electronic Record (SDER)

 

This pilot project was the result of a partnership with Informing Healthcare (the IT programme for NHS Wales) resulting  in the integration of individual patient electronic diabetes records from primary and secondary care into one database by 2007 which could be accessed from both hospitals and 85% of local GP surgeries. The project could not be sustained on a locality basis, but has demonstrated that shared electronic records facilitate clinical management by reducing gaps in the clinical records and also help to avoid duplication of care. There are now plans to adopt an all Wales diabetes database in secondary care and to link this to the established GP systems.

 

Prosiect Sir Gâr (The Carmarthenshire Project)

 

. The project’s main aims are to achieve reductions in a) mortality and b) morbidity from cardiovascular disease significantly in excess of that which would be expected as a natural trend over a timescale of 10 years in residents of Carmarthenshire aged 35-74 years.

The partners involved in this project are:

          Hywel Dda Health Board

          Swansea School of Medicine

          The National Public Health Service

          Carmarthenshire County Council

          Diabetes Reference Group

          Corus Steelworks, Trostre

          Astra-Zeneca, Sanofi-Aventis, Schering-Plough, Pfizer and Lilly Pharmaceuticals

 

In the pilot phase of the project which began in Sept 2009 we have conducted cardiovascular health checks on 300 employees of Corus and of the Hywel Dda Health Board aged over 40. Results are summarised in the following table:

 

QRISK2 >20% (high CV risk)

3.7%

QRISK2 10-20% (intermediate CV risk)

15%

HbA1c>6.5% (probable diabetes)

1.3%

HbA1c 6-6.5% (Impaired glucose regulation)

5.7%

Total Cholesterol:HDL ratio >6

13%

BP>140/90 (either or both)

33%

BMI >30

31%

Waist circumference >94cm (male) or >80cm (female)

70%

As a result, 18% were referred to the dietitian, 24% to primary care for possible pharmacological management and 15% to the intensive lifestyle management course.

 

Patient participation

 

Patients continue to be represented at all stages in the design and delivery of diabetes services. The Carmarthenshire Diabetes Patient Reference Group meets regularly before each Diabetes Network meeting to discuss a range of issues relevant to the local diabetes services. Five members of this group also attend the Network meetings where these issues are further discussed.

 

Structured patient education

The Community Diabetes Nurse Specialists, along with the dietitian, continue to deliver the XPERT structured education course for people with type 2 diabetes funded from charitable sources until NHS funding is forthcoming. From 2006-2009, 18 courses have been completed by 237 participants.  The Table below summarises the results:

Education of healthcare professionals

 

The following are examples of educational courses designed and/or delivered by our multidisciplinary diabetes team:

 

  • Link Nurse Training: a link nurse from each clinical area within the Trust attends for diabetes training sessions with the diabetes nurses every 3 months
  • Diabetes Update for Nurses: a two day course for nurses within the Trust
  • Annual Diabetes Update Day for certificate trained diabetes staff: the last one was held in June 2009 and was attended by over 120 diabetes care professionals from Carmarthenshire and the rest of West Wales.
  • Podiatry Training Day for Practice Nurses to enable them to examine diabetic feet competently.
  • Diabetes Training Days were also organised by the Community Diabetes Nurse Specialists for Care Home and Social Services staff.
  • The hospital based diabetes team also delivered Merit I and Merit II courses to local GP’s and Practice Nurses to enable them to care for patients who require insulin.
  • We are now into our third year for delivering the Swansea Masters level module in Diabetes. Five courses involving 70 participants have been held so far, including one held in the St David’s Education Centre in Carmarthen. We are planning further courses at Withybush and Bronglais in 2010.

 

Diabetes Network

 

The Hywel Dda Health Board was formed in October 2009 following amalgamation of the former separate Carmarthenshire, Ceredigion and Pembrokeshire acute Trusts and LHB’s into a single organisation. To aid the process of integration of local diabetes services the Hywel Dda Diabetes Network was established in 2008. The Network is an inclusive group with representation from all the important local stakeholders in diabetes. These include the hospital based diabetes teams, Community Diabetes Nurses, GP’s, health managers, patients and the voluntary sector. It provides the focus for strategic planning of local diabetes services. In addition individual group members, in their capacity as leaders of the various components of the local diabetes services, are also able to implement agreed developments in service delivery.

 

 

Carmarthenshire Chronic Conditions Collaboration (C4)

 

The Carmarthenshire Chronic Conditions Collaboration has by now acquired flagship status from the Welsh Assembly Government. The aim is to coordinate the development of services (including social services)for the management of diabetes, ischaemic heart disease and chronic pulmonary disease, in appropriate settings that minimise the burden on the acute sector. The appointment in 2006 of three Community Specialist Nurses in each of these specialties is already helping to achieve this aim. We have evidence of reduction in acute hospital admissions among these patient groups. This model has also proved a powerful catalyst to breaking down the barriers between primary and secondary care services.

 

Research and Clinical Trial work

 

Our Clinical Research Fellow completed a study titled “Microvascular and Macrovascular complications in screening versus symptom diagnosed type 2 diabetes: an observational study”, which was presented at the annual Diabetes UK Conference in Glasgow in March 2009.

We also participated in studies on prandial insulin commencement (LanScape) ad basal insulin follow –up (ATLANTUS).

 

Clinical Audit and Quality Assurance

 

The Diabeta 3 EPR has been in use at PPH since 2000 and in WWGH since 2002.  The diabetes details of inpatients as well as outpatients with are entered onto the system and the number reached 8,275 by the end of 2009. This represents approximately 80% of those recorded on GP diabetes registers in Carmarthenshire and South Ceredigion. The figure below shows their age distribution in decades and their absolute numbers. Type 1 diabetes was present in 13% and type 2 in 87% of patients.

The percentage of patients with a serum total cholesterol level above the level of  5mmol/l is shown below:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Mean serum total cholesterol in 2009 (PPH and WWGH combined) was 4.2 mmol/l.

For people with type 1 diabetes mean total cholesterol was 4.4 mmol/l.

For people with type 2 diabetes mean total cholesterol was  4.1 mmol/l.

 

Cardiovascular prophylaxis: lipid lowering drugs

 

The percentage of patients taking stains or other lipid lowering agent has increased progressively as shown below:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


The total percentage of patients taking lipid lowering agents (PPH and WWGH combined) in 2009 was 74%.

The percentage of type 1 patients taking lipid lowering agents was 50% (including 84% of those aged>40). The percentage of type 2 patients taking lipid lowering agents was 89%.

Cardiovascular prophylaxis: antiplatelet agents

 

Aspirin or other anti-platelet prophylaxis likewise increased progressively as illustrated below.

The overall mean percentage of people with diabetes taking anti-platelet agents in 2009 was 63%.

The percentage of type 1 patients taking aspirin was 33% (including 70% of those aged>40).

The percentage of type 2 patients taking aspirin was 76%.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cardiovascular prophylaxis: ACE inhibitors and angiotensin blockers

 

The percentage of patients taking either ACE inhibitors or Angiotensin II receptor blockers (ARB’s) was as follows:

 

The total percentage of people with diabetes taking ACEI’s or ARB’s in 2008 was 63%.

The percentage of type 1 patients taking ACEI’s or ARB’s was 41% (including 67% of those aged >40).

The percentage of type 2 patients taking ACEI’s or ARB’s was 76%.
