Provider Clinical Inertia Primary reasons providers fail to intensify treatment Overestimation of care provided i.e., providers overestimate their adherence to guidelines and the care they provide Citing soft reasons to avoid intensification of treatment i.e., perception that the overall care of their patient is improving, nonadherence among patients, and concerns about results from recent large CV trials Lack of training Khunti K, et al.

Responding to Patient Fears and Misconceptions about Insulin. Less than % of insulin naïve patients feel insulin is beneficial In the past, insulin was started too late when complications already occurred Clinical trials show the benefit of blood-glucose control in decreasing the risk of microvascular complications. 5% see insulin as a punishment and self blame Explain that a decrease in insulin production is a natural progression of diabetes 3. 5% fear injection Start with injection a day and have patient self inject in the office Prescribe an insulin pen.

Case Steve Follow-up Over the next months, Steve titrated his basal to units at bedtime At a 3-month follow-up, his AC was at 6.8% Steve is very happy with this blood-sugar control and tells you that in the 9 years since he has been diagnosed, this was the first time his AC is 7.% Summary Type diabetes progresses and requires ongoing review to match therapies with individual needs Be aware of clinical inertia, as it is common in clinical practice and is a major barrier to achieving glycemic control in patients with type diabetes The ideal initial insulin therapy would provide effective and stable glycemic control for a full h with minimal and weight gain
Summary New ultralong-acting basal insulins (U3 glargine and degludec) have advantages over currently available analogs basals including: Longer durations of action ( 36 hours) Significantly less overall and less nocturnal Have less variability with a flatter and more even PK/PD profile When using combination medications with insulin, consider newer insulin options that lower the risk of and weight gain and minimize other side effects Questions?
