Research outcomes

The primary endpoint at ten year follow up is the modelled 10-year risk of cardiovascular disease

Secondary endpoints at ten year follow up include:

  1. Time to first event of composite CVD endpoint. This compromises of CVD mortality, CVD morbidity (non-fatal stroke, non-fatal myocardial infarction, all revascularisations, amputations (except for traumatic)).

  2. All cause mortality.

  3. Changes in biochemical outcomes including HbA1c levels, total, HDL & LDL cholesterol and triglycerides collected through medical records.

  4. Microvascular endpoints: Neuropathy measured by the Michigan neuropathy questionnaire; Renal function through Albumin Creatinine ratio (ACR) & estimated glomerular filtration rate (eGFR) blood results; and development of eye complications through assessment of latest retinal image and eye examination.

  5. Most recent clinical height and weight measures and blood pressure readings from medical records.

  6. Other health status outcomes such as smoking status, alcohol consumption, physical activity (IPAQ) through self report questionnaire.

  7. Functional status (SF36); health utility (EQ5D); quality of life and well being measures specific to diabetes (AddQoL & DTS); and health service use and prescribed medication(Adapted Aberdeen HSRU).

  8. Quality of GP/Nurse therapeutic relationship using an approved adapted version of the CARE measure.

  9. Diet, using a FFQ previously delivered at 5 year follow up.

  10. Additional physical activity data using EPAQ2.
