3. Research use of diabetes registries • Specific study question • Representative samples • Valid methods

4. Research use of diabetes registries focusing on Quality Indicators • Patientrelated factors • Doctors and nurses • Current guidelines • Health care organisation / management

5. Research use of diabetes registries • Identification of cohorts • Patient related factors • Hypertension • GUIDANCE

6. Skaraborg Primary Care • Serving a population of 260 000 inhabitants • 15 municipalities • 24 health care clinics (3 hospitals) • 135 family physicians

7. Skaraborg Primary Careregular follow-up of about… • 30 000 patients with hypertension • 10 000 patients with diabetes • 3000 patients with heart failure

8. Skaraborg is a regional sample • Good information on the background population • Fairly complete data in primary care data registry • It should be possible to contribute with most relevant indicatiors

9. DM in The Skaraborg SPCD

10. Blood pressure <140/90 mm Hg

11. BMI ≥30 kg/m2

12. Identification of cohorts • Longitudinal follow-up using different health data registries

13. Identification of cohortslongitudinal follow-up • SPCD 2010: All patients seen with diabetes are identified as a cohort • Linkage to: National Mortality Register National hospital in-patient register National prescription register Tax authorities for income, work and edu • Ethical board has to approve this

14. Research use of diabetes registries focusing on Quality Indicators • Patientrelated factors • Doctors and nurses • Current guidelines • Health care organisation / management

15. Patient related factors • Physical activity (self-reported) • Smoking

16. Patient related factos and QI’s in diabetes – SPCD Sweden 2008 • Significant association between low physical activity and - higher BMI (p<0.001)- Poorer HbA1c (p<0.001)- Lower HDL (p=0.011 m and p=0.014 w) • In females smoking was associated with higher BMI (p=0.027) and higher LDL (0.046)

17. Hypertension in type 2 diabetesEUBIROD - opportunities • Review hypertension control in diabetes over EU using the same tool to collect data • Compare contexts and settings for delivery of diabetes care • Epidemiological tool to survey changes in QI’s over time using a standard method • Feedback to the clinics for quality assurance

18. Hypertension in type 2 diabetesEUBIROD - limitations • Selection bias – different contexts and settings in different regions • Standardisation of variables: Validity of ”type of diabetes” must be improved

19. Hypertension in type 2 diabetesEUBIROD - possibilities • Patient related factors: lifestyles, comorbidity • Factors linked to the health care providers -organization -staff • Variation according to local therapeutic guide-lines • Define a cohort to follow longitudinally for complications

20. GUIDANCE Initiated by EASD • 8 countries each collecting 1000 patients • Cross-sectional survey of quality indicators vs patient related factors, staff factors Health care organisationGUIDLINES

21. GUIDANCE Stone MA, Wilkinson JC, Charpentier G, Clochard N, Lindblad U, Müller UA, Nolan J, Rutten GE, Trento M, Kamlesh Khunti K, on behalf of the GUIDANCE Study Group.
