Q

What is the basal/bolus insulin regimen and who is it suitable for?

A

history of hypos, decreased awareness, impaired renal funtion, dementia, alcohol misuse, starvation and high exercise, food malabsorption, glucose level less than 3mmol/L

32
Q

What counselling should be given around injection technique?

A

Wash hands, roll bottle, draw up correct dose, clean and pinch injection site, safely discard.
Rotate the injection site to prevent lipohypertrophy which can lead to insulin dumping

33
Q

How do you calculate the amount of insulin an individual will need to follow sick day rules?

A

Calculate total daily dose (total of all meal time and background insulin) and calculate 10-20% of this

34
Q

Which medications should be stopped according to sick day rules?

A
Metformin - can make you dehydrated 
sulfonylureas
gliclazide, glibenclamide, gliplizide
exenatide, liraglutide, semaglutide,
flozins
ace inhibitors
ARBs
35
Q

How should blood sugars and ketones be managed on sick days?

A

Check blood sugars and ketones

36
Q

How should a patient act if they have tested their blood glucose and their ketones are less than 1.5mmol/L?

A

Sip sugar free fluids
Test blood glucose and ketones every 2-4 hours
Usual insulin:carb at meal time
use corrective quick acting insulin if blood glucose is raised
when unwell, may need larger bolus to reduce
if glucose levels above target, consider a 10-20% increase in basal dose

37
Q

How should a patient act if their blood ketones are more than 1.5mmol/L or blood glucose is above 13mmolL

A

Sip sugar free fluids
test blood glucose or ketones every 2 hours
calculate total daily dose from previous day

38
Q

What should a patient do if their blood ketones are 1.5-3mmol/L on blood test

A

Give 10% of TDD as quick acting insulin every 2 hours plus usual insulin:carb if eating. basal dose may need a 10-20% increase in basal dose.
If ketones still present, go back and result

39
Q

What should patients do if their ketones are over 3mmol/L on a blood test

A

Give 20% total daily dose as quick acting insulin, plus usual insulin:carb. May need to increase basal by 10-20%. If ketones still present, go back and restart process

40
Q

What should a patient do if ketones are still present after 4-6 hours or if they vomit

A

go to hospital as it is an emergency

41
Q

What are the driving rules?

A

Check blood glucose less than 2 hours before the start of a journey and every 2 hours after driving has started. If 5.0mmol or less, eat a snack. If 4.0mmol or less don’t drive. Don’t drive until 45 mins after reading is 5mmol/l. tell DVLA if more than 1 sever hypo when driving in last 12 months.

42
Q

What is diabetic ketoacidosis?

A

severe lack of insulin so body uses fat for energy instead of sugar, releases ketones
Ketone build up leads to blood becoming acidic

43
Q

What are the symptoms DKA?

A

Toilet, thirsty, tired, thinner, confusion, blurred vision, stomach pain, feeling pain, sweet/fruity smelling breath.

44
Q

How should you avoid DKA?

A

Monitor sugar levels and alter insulin in response to what you eat

45
Q

What is the treatment pathway for type 2 diabetes?

A

Manage lifestyle issues
Offer a structured education programme DESMOND.
Target HBA1c 53mmol/L measure 3-6 monthly
1st line metformin dose gradually increased to minimise GI AEs
Monitor renal function <45mL/min.1.73m2 review dose, stop if <30mL/min.1.73m2

46
Q

What should be given to type 2 diabetic patients if Metformin is contraindicated?

A
If metformin is not tolerated or C/I 
– Gliptin - sitagliptin
– Pioglitazone
– Sulphonylurea - gliclizide
– SGLT-2i - canagliflozin
47
Q

What can be done if patients have GI disturbances due to metformin?

A

Give m/r metformin

48
Q

What should be given second line for type 2 diabetes if metformin is ineffective?

A

For people for whom metfomin is ineffective combine metformin with:
–Gliptin
–Pioglitazone
–Sulphonylurea
–SGLT-2i
For those who don’t tolerate metformin combine:
–Gliptin plus pioglitazone
–Gliptin plus sulphonylurea
–Pioglitazone plus sulfonylurea
–Substitute a SGLT-2i instead of a gliptin

49
Q

What should be given if second line diabetes treatment fails?

A

If second line fails:
For people who can take metformin:
– Triple therapy with metformin, a gliptin, and a sulfonylurea, or
– Triple therapy with metformin, pioglitazone, and a sulfonylurea, or
– Triple therapy with metformin, pioglitazone or a sulfonylurea and an SGLT-2i. (The SGLT-2i dapagliflozin in a triple therapy regimen is recommended as an option for treating type 2 diabetes in adults, only in combination with metformin and a sulfonylurea NOT pioglitazone), or
– Starting insulin-based treatment.
For people in whom metformin is contraindicated or not tolerated:
– Consider starting insulin-based treatment.

50
Q

What should be given in type 2 diabetes if third line treatment fails?

A

For people on triple therapy with metformin and two other oral antidiabetic drugs, consider combination treatment with metformin, a sulfonylurea, and a glucagon-like peptide-1(GLP-1) mimetic (exenatide) for:
– Adults who have a body mass index (BMI) of 35 kg/m2 or higher (adjust accordingly for people from Black, Asian and other minority ethnic groups) and specific psychological or other medical problems associated with obesity, or
– Adults who have a BMI lower than 35 kg/m2 and insulin therapy would have significant occupational implications, or weight loss would benefit other significant obesity-related comorbidities.
For people on insulin-based treatment:
– Seek specialist advice (or refer the person to their diabetes team) for consideration of treatment with a GLP-1 mimetic plus insulin.
