  1. Who should access pump therapy? UK perspective Dr Thomas Ulahannan International Diabetes Federation European Region General Assembly Together We Are Stronger Warsaw, Poland 3-5 November 2006

  2. Who should access pump therapy? • Clinical criteria many potential indications • Patient preference option in intensive insulin therapy • Health Economic criteria resource limitations/cost effectiveness

  3. Location of Gloucestershire in UK

  4. NHS Hospital Services in Gloucestershire • Gloucestershire Hospitals NHS Foundation Trust serves a population or around 500,000 • CSII is based at Gloucestershire Royal Hospital • 18, 000 diabetes patients in county • 1,800 type 1 diabetes under hospital follow up • 55 current pump users

  5. UK National Institute for Health and Clinical Excellence (NICE) • independent organisation responsible for providing national guidance on the promotion of good health and the prevention and treatment of ill health • Technology Guidance 57: Continuous subcutaneous insulin infusion for diabetes (February 2003) determines NHS eligibility for CSII

  6. Technology Guidance 57 • recommended CSII as an option for people with type 1 diabetes provided that • Multi Dose Injection (basal-bolus) therapy (including, where appropriate, the use of insulin glargine) has failed, • and those receiving the treatment have the commitment and competence to use the therapy effectively

  7. Continuous Subcutaneous Insulin Infusion at 25 Years Evidence base for the expanding use of insulin pump therapy in type 1 diabetes John Pickup, Harry Keen, Diabetes Care 25:593-598, 2002 • randomized controlled trials indicate in type 1 diabetic subjects, the glycemic control on CSII is comparable with or only slightly better than MDI • Pumps are relatively costly and special expertise needed • If patients are doing well on MDI, CSII is not indicated • After optimized MDI a trial of CSII is appropriate if poor control persists because of 1) frequent unpredictable hypoglycemia or 2) a marked dawn blood glucose rise.

  8. Continuous Subcutaneous Insulin Infusion at 25 Years Evidence base for the expanding use of insulin pump therapy in type 1 diabetes John Pickup, Harry Keen, Diabetes Care 25:593-598, 2002 • Patients with erratic blood glucose concentration will fall into the first category when attempts to improve control lead to frequent hypoglycemia • CSII is an effective means of managing diabetes during pregnancy but these patients, as a group, are not better controlled than during multiple injections

  9. What is MDI failure? • Defined as inability to achieve stable HbA1c <7.5% (or 6.5% with complications) without recurrent hypoglycaemia • Therefore restricts CSII to a subgroup of Type 1 diabetes only but permits use in children and pregnancy

  10. Benefits of NICE guidance • Provides NHS funding for the pump, consumables, upgrades and clinical staff time as long as criteria are met • All hospital appointments, consultations and training are provided without cost to the patient

  11. To the patient To the hospital To primary care To the NHS To wider society Glycaemic control Reduced admissions Less appointments Lower costs More productivity Potential benefits of CSII

  12. Assessing benefits of CSII • Previous studies have used economic models of projected long-term costs and outcomes of continuous subcutaneous insulin infusion (CSII) compared with multiple daily injections (MDI) in patients with Type 1 diabetes • Scuffham P and Carr L. The cost-effectiveness of continuous subcutaneous insulin infusion compared with multiple daily injections for the management of diabetes. Diabet Med 2003; 20: 586 – 593.

  13. Economic methods • Typical measures • quality adjusted life expectancy (QALE) • incremental cost-effectiveness ratio (ICER) and quality-adjusted life year (QALY) • A common assumption is that improvements in glycaemic control associated with CSII lead to improved QALE by reduced incidence of diabetes-related complications • ICER of £25 648 €38 215 (£1=€1.49) per QALY gained is considered to represent good value for money by current standards in the UK.

  14. Drawbacks of this approach • local population and clinical conditions in which a pump service operates differ significantly from those assumed in the models • cost savings from avoidance of complications of diabetes may take years to realize. • front line clinicians and managers may not always be familiar with the economic modeling and measures such as QALE, ICER and QALY.

  15. alternative to economic models • directly monitoring of the effects of CSII introduction on • relevant and important healthcare usage using the NHS national tariffs • in a single district general hospital • and in local primary care providers.

  16. Patients and Methods • Patients commencing CSII over a five year period between June 2000 and June 2005 inclusive were seen in a single district general hospital by one pump team • Patients were selected for CSII according to NICE criteria (13) after these were available. Prior to NICE guidance, Type 2 diabetics were not excluded from consideration. • All patients received intensive general diabetes education and carbohydrate counting training, initially on a one to one basis, and latterly using the REACCT (Re-Education And Carbohydrate Counting Training) programme (developed from DAFNE) • DAFNE Study Group. Training in flexible, intensive insulin management to enable dietary freedom in people with type 1 diabetes: dose adjustment for normal eating (DAFNE) randomised control trial. BMJ 2002; 325 (7367): 746-751. • Ross WI, Davies FC, Ulahannan TJ Re-Education And Carbohydrate Counting Training: REACCT Diabetic Medicine 2006; 23 (supp 2):96

  17. Patient Management • Suitability for a trial on pump therapy was decided jointly by the pump team if stable glucose control was not achieved despite intensive education and use of basal-bolus insulin regimes including insulin analogues where applicable. • Patients not willing to comply with recommendations were not considered further for pump therapy. • After 3 months patients were reassessed and if it was agreed by the pump team that the therapy was of benefit to the patients, they remained under the care of the same specialist team for pump therapy. • Healthcare resource utilization before and after CSII initiation were compared.

  18. Data Collection • Data was collected for a maximum time of 60 months (5 years) before and after 60 months after CSII initiation • Routine hospital data was obtained on outpatient appointments in diabetes clinics appointments in other departments • Hospital admission and discharge data was also reviewed • http://www.dh.gov.uk/assetRoot/04/13/44/04/04134404.xls

  19. Clinical variables Before and After Pump Initiation

  20. Clinical variables Before and After Pump Initiation

  21. Appointments to see diabetes consultants, diabetes nurses and other specialties and admissions to hospital for diabetes or other causes according to hospital PAS data before and after CSII therapy

  22. Estimated Savings on primary care costs/resource utilisation audit

  23. Estimated Savings on Hospital Resource Utilization

  24. Practical Lessons • CSII has resource benefits as well as costs • Benefits occur in primary and secondary care • Demonstrating these benefits strengthens the case for continued funding of the pump programme • We cannot say whether the same outcomes would apply with wider usage of CSII • This is not a randomised trial only observational data

  25. Conclusions: Who should access pump therapy? • When there is clinical benefit • Definition of benefit • When the resources allow • Definition of cost effectiveness • Effects of Insulin Pump Therapy on Local Healthcare Resource Utilisation of Insulin Pump Therapy T Ulahannan, N Myint, KF Lonnen submitted
