Key Question
What are the barriers for your patients with
type 2 diabetes regarding initiation of
insulin therapy?
1. Concern that insulin use is “forever”
2. Fear of injection
3. Equating insulin use with worsening diabetes
and complications
4. Fear of weight gain

Patient Barriers to Insulin Use:
Perception vs Reality
Perception
Reality
Failing oral therapy
58% of patients believe using
insulin means they have failed
OAD therapy
OAD failure is due to progressive nature
of type 2 diabetes; insulin is best agent to
control disease
Needle phobia
Fear associated with early
experiences
Current needles considered painless;
easy-to-use injection systems are available
Fear of complications
Common association of insulin
with diabetic complications
Complications are due to uncontrolled,
progressive disease; insulin actually results
in reduction of vascular damage
OAD = oral antidiabetic drug.
Meese J. Diabetes Educ. 2006;32:9S-18S; Peyrot M et al. Diabet Med. 2005;22:1379-1385.
Clinician Barriers to Insulin Use:
Perception vs Reality
Perception
Reality
Hypoglycemia is prevalent
with insulin use
Severe hypoglycemia is very uncommon
in patients with type 2 diabetes, occurring
at 10% the rate in patients with type 1
diabetes
Insulin use increases
atherosclerosis
Studies indicate no exacerbation of
cardiovascular disease
There is weight gain with
insulin use
Weight gain is modest and can be
controlled with diet and exercise
Patients have a negative
attitude regarding insulin use
Insulin is a “positive” approach to achieving
glycemic control

Next Steps…
 What do we do for the patient who has failed on 1 or
2 oral agents?
Basal Insulin Therapy
 Usual first step when beginning insulin therapy
 Continue OAD and add basal insulin to optimize FPG
 A1C of up to 9.0% often brought to goal by addition of basal
insulin therapy to OADs
 Easy and safe: patient-directed treatment algorithms with
small risk of serious hypoglycemia
 ADA and EASD recommended: “Although 3 OADs can be
used, initiation and intensification of insulin therapy is
preferred based on effectiveness and expense”
FPG = fasting plasma glucose.

glycemia with OADs
 Displays anxiety about injections
 You explain the progressive nature of diabetes:
 Convey that insulin injections are the best way
to achieve glycemic control
 Describe injection options (“painless” needles,
injector pens, etc)
 Indicate that you and the patient will be a “team”
in getting to the A1C goal

Case Study (cont’d)
 Patient is taking 75 U with FPG controlled
(<100 mg/dL to rarely >110 mg/dL) since last
visit 4 months ago
 Patient’s last A1C = 6.9%, monitoring occasional
postprandial blood sugars
 Patient finds insulin injections painless and after
speaking with you, feels that he is now a partner in
his therapy program
Case Study (cont’d)
 Over the next 3 years, patient seen for routine
follow-up every 3 to 4 months
 Remains medically stable, with A1C values
6.5% to 7.2%
 3.25 years after adding basal insulin glargine,
A1C has increased to 8.2%, however, FPG checks
remain <120 mg/dL
Decision Point
What do you do now?
1. Increase glargine
2. Switch to twice-daily premixed
3. Switch to 4-shot basal-bolus program
4. Increase monitoring to AC and HS, and
have patient report after 2 weeks

AC = before meals; HS = at bedtime.
?
Case Study (cont’d)
 Because the patient’s FPGs are good and post-
prandial glucose levels are high, the decision is
made to switch to twice-daily premixed insulin
 The patient is encouraged to increase daily
monitoring to adjust insulin dose

Case Study (cont’d)
 Decision is made to switch to basal-prandial therapy
to reduce hypoglycemia and postprandial highs
 60% of patient’s total daily insulin dose is given as
basal insulin – 54 U glargine qhs titrated to
FPG 100-110 mg/dL
 Before the main meal, a rapid-acting analog is
added: glulisine, initiated at 5 units, up-titrated using
a treat-to-target algorithm
 Patient continues to self-monitor glucose

Advantages of Rapid-Acting Analogs
 Short duration of action—fewer between-meal “hypos”
than regular insulin
 Flexible mealtime dosing
 More consistent kinetics
 Day to day
 Across anatomical sites
 With large doses
 Slightly faster onset of glulisine action (compared
to lispro) in obese and morbidly obese subjects
(independent of BMI)*

Decision Point
The best time to use a rapid-acting insulin
analog is:
1. Before a meal
2. After a meal
3. Either works well

Case Study (cont’d)
 At 6-month follow-up patient is doing well with
70 U glargine and 10 U to 17 U glulisine at supper
 Actual dose adjusted by
 Meal carbohydrate content
 Activity
 Insulin supplement of additional 1 U for every
25 mg/dL above 130 mg/dL (prandial glucose)
 A1C = 6.3%
 He feels well, has infrequent “hypos,” and is pleased
with his blood glucose control
PCE Takeaways
PCE Takeaways: Basal-Prandial Insulin
Replacement
1. An effective insulin treatment strategy provides
both basal and postprandial insulin coverage
2. Initially, prandial insulin may be needed only at the
largest meal of the day, with coverage at other
meals added based on prandial glucose levels
3. Rapid-acting insulin analogs closely match normal
mealtime insulin patterns
