  1. Diagnosis is Failure Changing trends in Diabetes in a GP Practice Tim Walter

  2. Background • Falkland Surgery population of 14,500 in Newbury • Market Town • Main practice demographic is of an average age split but higher than average elderly population c.f. locally (75yrs+) • Some pockets of deprivation • High level of employment

  3. Trends • 2000 Type 1 DM = 44 Type 2 DM = 150 (194) • 2005 Type 1 DM = 56 Type 2 DM = 250 (306) • 2008 Type 1 DM = 66 Type 2 DM = 369 (435) • 2012 Type 1 DM = 73 Type 2 DM = 399 (472) • Therefore the massive increase in DM is predominantly in the Type 2 group • About 3.5% of population

  4. Why diagnose early? • At diagnosis UKPDS showed • 39% H/tension • 24% microalbuminuria • 24% ECG changes of Ischaemia • 50% had some sort of complication

  5. “Pre-diabetes” • IGT, IFG, Gestational DM, metabolic syndrome etc • Now also looking to include a “Risk Assessed” group • Conversion Rates • Not clear what conversion rate of risk scored pts might be • But IGT carries approx. 50% 10yr conversion rate to DM • Risk reduction • In USA up to 58% reduction in progression to DM with lifestyle intervention (71% in older pts) • DPP showed 16% risk reduction per Kg lost

  6. QDiabetes at Falkland Surgery • In practice we looked at a subgroup of pts • age 35+, BMI > 35, excluded other med problems • Chose this population to restrict workload • Calculated score and selected pts with 10yr risk score of 20% or more (50 pts) • i.e. 1 in 5 of these patients predicted to develop DM in the next 10 yrs • Most will be “normal”, some have IGT, some have DM

  7. Results from Selected Group • Average Age 60 • Average HbA1c 40 • 13% pts with HbA1c > 42 (non DM threshold) • 16% pts with fasting BS > 5.6 • QDiabetes scores 20-49.9% • Often large variation in QRisk and QDiabetes scores for an individual eg 8% vs 49%, 10% vs 30% (Ave 15% vs 30%)

  8. Project • Invitation to participate • Baseline blood tests (Renal, Fasting BS, Cholesterol, HbA1c, LFTs etc) • Nurse appt to record details of weight, waist, smoking etc • Randomly allocated to two intervention groups • 10 week Eat4Health vs 10 week Walking4Health • Repeat measurements

  9. Interventions • Eat4Health • Established, effective, 10 week group sessions looking at diet, exercise, attitudes to food and diet • Walking4Health • 1/2hr co-ordinated walking program over same time period • Repeat monitoring • Rollout to other local practices if successful

  10. Eat4Health – Waist Circumference

  11. Eat4Health – Weight Loss

  12. Eat4Health - Activity

  13. Summary • Small scale project (approx 25 pts) • Workable, practical application of evidence based tools • Transferrable • Issues • Does it work, short-term, long-term? • Short term costs, longer term benefits if it does work • Costs approx £20 plus bloods, plus admin per pt

  14. Proposed plans for the CCG • Identify at risk groups • Promote the use of QDiabetes across populations • Support the workload involved across the CCG • However, useless unless action taken as a result • Intervention for identified patients • Eat4Health • Walking4Health • Other surgery based initiatives

  16. Qdiabetes • http://www.bmj.com/content/338/bmj.b880.full • Qresearch - 11 million pts • Integrated within Emis • 25-79yr olds M&F • Cohort of 2.5 million pts

  17. Other stuff for reference • Ignore slides below

  18. Early Detection • Computer system analyses and flags up patients with previously raised sugar levels. Work done in University of Warwick, published in BMJ and we have been running this for about 2 years • Random BSs over 11, fasting over 7 without codes to indicate diagnosed already • Looked at 12 patients with potentially missed DM, 9 were subsequently confirmed • Ongoing process as new patients arise • Second group with random BS over 7

  19. National Initiatives • We need to see co-ordinated education and action • Publicity on healthy living • Labelling • Role models • Newspapers/Magazines/Advertising • Prevention better than cure • However this costs money now, but won’t show results for many years
