In-Hospital Management of Hyperglycemia: The Role of Insulin Degludec.

introductionHyperglycemia is a common and challenging condition in hospitalized patients both with and without a history of diabetes. Managing hyperglycemia effectively is critical in reducing complications, mortality, and the length of hospital stays. Insulin degludec (IDeg), an ultralong-acting basal insulin, has a well-established efficacy and safety profile in terms of managing hyperglycemia in outpatients; it has demonstrated benefits in clinical practice across various patient populations. This review aims to assess the evidence on its clinical suitability, as well as efficacy and safety, for managing hyperglycemia across different inpatient populations. The review specifically focuses on outcomes such as glycemic control, glycemic variability, safety (particularly hypoglycemia risk), dosing flexibility, ease of titration, and use in special populations.

methodsA comprehensive literature search was conducted using PubMed to identify studies published between 2014 and 2024. Eligible studies included randomized controlled trials, real-world evidence, and case series that examined the use of IDeg for hyperglycemia management in hospitalized patients.

resultsThe reviewed studies consistently demonstrated that IDeg provides stable and predictable glycemic control with low glycemic variability. The ultralong duration of action, ability to be titrated daily, and flexibility in dosing make IDeg suitable for noncritical care settings with difficult-to-maintain rigid insulin schedules. Furthermore, the risk of hypoglycemia, particularly nocturnal hypoglycemia, is low with IDeg. These attributes are beneficial across diverse inpatient populations. Practical advantages, such as ease of administration with a specialized delivery device, further support its use in hospital settings.

conclusionsUnique pharmacokinetic and pharmacodynamic properties of IDeg, reduced glycemic variability, low hypoglycemia risk, ease of daily titration, and dosing flexibility make it appropriate for managing hyperglycemia in hospitalized patients.
