Audit of correlation between number of pots of strips used and HbA1c amongst diabetics at Tilehurst ((There is no correlation at all!)
Think: why is he testing? What will he do with the result? What will YOU do with the result?
Who should use them? • Diabetics who use insulin – Type 1, and Type 2 who use insulin • Women with gestational diabetes • Some patients who use sulphonylureas (eggliclazide), especially if they drive • Other patients with intercurrent illness
And who should not use them (usually)? • Everybody else!!
Why test at all? • To detect hypo- and hyper-glycaemia in diabetics who use insulin (and SUs) • To help patients prevent immediate serious illness (hypoglycaemic attacks and DKA) • As part of the long-term management of diabetes to maintain good control and prevent micro- and macro-vascular complications
Targets for SMBG • In Type 1 DM • Before meals 4-7mmol/l • 2hrs after meals < 9mmol/l • In Type 2 DM • Before meals 4-7mmol/l • 2 hrs after meals < 8.5mmol/l
Monitoring in Type 1 DM • Twice daily insulin therapy • Test 2-3x day, varying testing times between fasting, premeal and postmeal to identify trends • Intensive insulin therapy (basal bolus) • Monitor 2-4x day normally • Monitor at least 4x day if they alter doses at mealtimes • More frequent testing during intercurrent illness
Monitoring in Type 2 diabetics who use insulin • Twice daily insulin regime • Test 1-2x day varying times between fasting, premeal and postmeal • Intensive insulin therapy (basal bolus) • Monitor 2-4x day normally • Monitor at least 4x day if they alter doses at mealtimes • Once daily insulin (basal regime) • Test fasting BG once daily during initiation, can then be reduced to 1-2x week)
How can we do better? • Naseem is going to talk some more about testing in Type 1 diabetes • We are going to introduce carbohydrate counting as a means of improving control in people with Type 1, and a very smart device to help patients calculate their correct dose of insulin
