Patient perspectives on the use of half-unit insulin pens by people with type 1 diabetes: a cross-sectional observational study.

BACKGROUND: Half-unit pens offer the ability to dose insulin more precisely. Information about half-unit pen use and evidence of their benefits and drawbacks is limited. This study aims to characterize people with type 1 diabetes (T1D) who have used (current/former = EVER) vs. those who have never used half-unit pens (NEVER users) and to understand their perspective. METHODS: An observational cross-sectional online survey was administered through T1D Exchange's online patient community, myGlu.org, to understand the use of half-unit insulin pens. RESULTS: The 278 adult participants (156 EVER, 122 NEVER) had a mean age of 41.8 ± 12.7 years, body mass index of 26.0 ± 3.8 kg/m2, glycated hemoglobin of 6.3% ± 1.0%, and 55% were male. EVER users had T1D for a shorter duration than NEVER users (p < .001). EVER users were less likely to use continuous subcutaneous insulin infusion (p < .001) and more likely to start correcting high blood glucose at a lower level (p < .001) and low blood glucose at a higher level (p < .001). The highest ranked benefits of half-unit pen reported by its current users (N = 131) included prevention of hyperglycemia (40.5%), less anxiety or worry (23.7%), and prevention of hypoglycemia (16.8%). CONCLUSIONS: Half-unit insulin pen is perceived as an insulin device that may help people with T1D to avoid hypo- and hyperglycemic events and decrease their level of disease worry and anxiety. This study highlights the need for patients and health care providers to understand the benefits of half-unit pens while considering options for individualized diabetes management.

Precision Dosing of Rapid-Acting Insulin Matters.

Despite several molecular and technological advances in insulin therapy and insulin delivery, global evidence highlights inadequate glycemic control in populations with type 1 diabetes (T1D) and type 2 diabetes (T2D). In this review, we discuss the importance of more precise dosing of insulin as one of the approaches to improve glycemic control while reducing hypoglycemic events. This report is based on the expert opinion of authors and literature search of articles relevant to the past and present insulin delivery devices in diabetes management, especially half-unit insulin pens. We describe the various factors that facilitate better glycemic control, focusing on the impact of appropriate insulin delivery device selection on diabetes management. Precision dosing of insulin is a lesser-studied factor that contributes toward better glycemic control. Insulin pens have consistently outperformed syringes as delivery devices due to their greater accuracy and precision of dosing, ease-of-use, and patient preference. These advantages make them better suited to administer insulin in hypoglycemia-prone insulin-sensitive people with T1D, particularly younger children and geriatric patients. Half-unit insulin pens further extend this benefit by delivering half-unit doses of insulin accurately. They may contribute to better management of diabetes by allowing flexible dosing for mealtimes and physical activities even in erratic diet situations or illnesses by offering corrective doses in small increments. They are ideal delivery devices for insulin-sensitive people with T1D who require greater accuracy and precision in insulin delivery to achieve more stringent glycemic control.

Approaches to rapid acting insulin intensification in patients with type 2 diabetes mellitus not achieving glycemic targets.

Type 2 diabetes mellitus (T2DM) is a growing problem in the USA, affecting 30.3 million Americans, or 9.4% of the US population. Given that T2DM is a progressive disease, intensification of rapid acting insulin (RAI) to address hyperglycaemia is often required. The American Diabetes Association and the European Association for the Study of Diabetes recommend individualizing the treatment approach to glucose control, considering factors such as age, health behaviours, comorbidities and life expectancy. There are several validated treatment algorithms in the literature, which can be helpful for providing guidance on initiation of RAI while simultaneously considering patient preferences and clinical needs during treatment intensification. This paper provides expert recommendations on prandial insulin regimens and how to use treatment algorithms to promote better glucose control through best practice guidelines. To help patients reach HbA1c targets through treatment intensification, the FullSTEP, SimpleSTEP, ExtraSTEP and AUTONOMY algorithms are discussed in this paper. KEY MESSAGES Clinical inertia should be prevented with timely intensification of therapy when HbA1c levels are greater than 7% (or rising above a patient's individual target) according to national guidelines. Increased personalization in the intensification of T2D treatment is necessary to improve HbA1c targets while addressing risk of hypoglycaemia, concern about weight gain, and overall health goals. Healthcare providers are encouraged to address glycaemic control with a variety of strategies, including prandial insulin, while developing evidence-based treatment plans on the basis of algorithms discussed in the literature.

An Expert Opinion on Advanced Insulin Pump Use in Youth with Type 1 Diabetes.

Among children and adolescents with type 1 diabetes mellitus, the use of insulin pump therapy has increased since its introduction in the early 1980s. Optimal management of type 1 diabetes mellitus depends on sufficient understanding by patients, their families, and healthcare providers on how to use pump technology. The goal for the use of insulin pump therapy should be to advance proficiency over time from the basics taught at the initiation of pump therapy to utilizing advanced settings to obtain optimal glycemic control. However, this goal is often not met, and appropriate understanding of the full features of pump technology can be lacking. The objective of this review is to provide an expert perspective on the advanced features and use of insulin pump therapy, including practical guidelines for the successful use of insulin pump technology, and other considerations specific to patients and healthcare providers.
