18. NICE - Diagnosing Diabetes Diabetes is diagnosed on the basis of history (ie polyuria, polydipsia and unexplained weight loss) PLUS • random glucose >= 11.1 mmol/l • OR a fasting glucose >= 7.0 mmol/l • OR 2 hour plasma glucose concentration >= 11.1 mmol/l 2 hours after 75g OGTT HbA1c >= 6.5% (48 mmol/mol) = diagnosis of diabetes

19. NICE - Glucose Control • Discuss individual HbA1c target level, • Encourage maintaining target unless side effects • Discuss how any reduction benefits future health. • Monitor 2–6 monthly until stable • Monitor 6-monthly once stable. • Self-monitoring of plasma glucose should be available: • to those on insulin treatment • to provide information on hypoglycaemia • to assess changes from medications and lifestyle • to monitor changes during intercurrent illness • to ensure safety during activities, including driving. • Discuss urine glucose monitoring if plasma monitoring is found to be unacceptable.

20. Dilemma of treatment Hyperglycaemia and hypertension risks V Distress to patient by treating V Risk of being able to report a hypo What would you do?

21. Diabetic review 1/ Janumet (Metformin and sitagliptin) 2/ Pioglitazone 3/ Gliclazide MR

26. “Specifically, the laws in Part IV of the Mental Health Act on treating people without consent, only apply to treatment for mental disorder. They do not apply to the treatment of physical disorders unless it can reasonably be said that the physical disorder is a symptom or underlying cause of a mental disorder”

27. Conclusion • Complex and interesting case due to overlap of physical and mental illness • Lessons learnt • 1 step at a time • Can’t treat one without the other • Doesn’t always fit NICE – do what you can • We rely a lot on patient co-operation!
