The Omnipod 5 Automated Insulin Delivery System was associated with favorable glycemic outcomes for people with type 1 diabetes (T1D) in two pivotal clinical trials. Real-world evidence is needed to explore effectiveness in nonstudy conditions. A retrospective analysis of the United States Omnipod 5 System users (aged ≥2 years) with T1D and sufficient data (≥90 days of data; ≥75% of days with ≥220 continuous glucose monitor readings/day) available in Insulet Corporation's device and person-reported datasets as of July 2023 was performed.

Despite the demonstrated benefits of using insulin, nearly a third of the patients with type 2 diabetes (T2D) are initially reluctant to initiate insulin therapy when it is first recommended by their healthcare provider (HCP). Several studies have documented the reasons for this phenomenon known as psychological insulin resistance (PIR) and also identified actionable strategies for HCPs to assist people with T2D to overcome their PIR. However, most strategies are based on the experiences of HCPs, rather than of patients.

Introduction: Many patients with type 2 diabetes mellitus (T2DM) delay initiation of insulin therapy despite healthcare professional (HCP) advice. This phenomenon has been referred to as 'psychological insulin resistance' (PIR), and various contributing factors have been identified. Studies discussing approaches to overcoming PIR are lacking.

Objective: A survey of US adults with type 2 diabetes mellitus was conducted to better understand patients' insulin initiation experiences and treatment persistence behaviors.

Research Design And Methods: Participants were recruited from consumer panels and grouped by basal insulin treatment pattern: continuers (no gap of ≥7 days within 6 months of initiation); interrupters (gap ≥7 days, resumed treatment); discontinuers (stopped for ≥7 days, not resumed). A quota of approximately 50 respondents per persistence category was set.

Objective: To understand participant perceptions about insulin and identify key behaviors of healthcare professionals (HCPs) that motivated initially reluctant adults from seven countries (n=40) who had type 2 diabetes (T2D) to start insulin treatment.

Research Design And Methods: Telephone interviews were conducted with a subset of participants from an international investigation of adults with T2D who were reluctant to start insulin (EMOTION). Questions related to: (a) participants' thoughts about insulin before and after initiation; (b) reasons behind responses on the survey that were either 'not helpful at all' or 'helped a lot'; (c) actions their HCP may have taken to help start insulin treatment; and (d) advice they would give to others in a similar situation of starting insulin.

Aims: To identify actions of healthcare professionals (HCPs) that facilitate the transition to insulin therapy (IT) in type 2 diabetes (T2D) adults.

Methods: Included were T2Ds in seven countries (n = 594) who reported initial IT reluctance but eventually began IT. An online survey included 38 possible HCP actions: T2Ds indicated which may have occurred and their helpfulness.

Aim: Real-world effectiveness of insulin therapy is affected by poor treatment persistence, often occurring soon after initiation. An international cross-sectional survey of people with type 2 diabetes mellitus (T2DM) has been conducted to describe reasons for non-persistence with insulin therapy.

Methods: Responders to an online survey in 7 countries were classified as continuers (no gap of ≥7days), interrupters (interrupted therapy for ≥7days within first 6 months, then restarted), and discontinuers (terminated therapy for ≥7days within first 6 months, no restart before survey).

Continuing use of medication is key to effective treatment and positive health outcomes, particularly in chronic conditions such as diabetes. However, in primary care, non-persistence (i.e.

Aims: To describe primary care physicians' (PCPs) perceptions of patient reactions and concerns about insulin initiation and identify opportunities for increased support.

Methods: Cross-sectional, online survey of PCPs prescribing basal insulin to adults with type 2 diabetes mellitus (T2DM). PCPs were identified from administrative claims of a large commercial health plan and descriptive results of PCP responses were reported.

Background: Poor treatment persistence can affect the real-world effectiveness of insulin therapy. A cross-sectional online survey in 942 patients with type 2 diabetes from 7 different countries evaluated patient experience when initiating basal insulin and the reasons behind insulin persistence patterns. Here, we report the quantitative results for the subset of patients from Germany.

Background And Objective: People with T2DM who initiate basal insulin therapy often stop therapy temporarily or permanently soon after initiation. This study analyzes the reasons for and correlates of stopping and restarting basal insulin therapy among people with T2DM.

Methods: An online survey was completed by 942 insulin-naïve adults with self-reported T2DM from Brazil, France, Germany, Japan, Spain, UK, and US.

Background And Objective: People with type 2 diabetes mellitus (T2DM) often interrupt basal insulin treatment soon after initiation. This study aimed to describe the experiences during and after basal insulin initiation among people with T2DM with different persistence patterns.

Methods: Adults with T2DM from France, Germany, Spain, UK, US, Brazil, and Japan were identified from consumer panels for an online survey.

Aims: Primary objective: Identify risk factors associated with severe hypoglycemia (SH) and investigate the association between mild hypoglycemia and SH in people with type 2 diabetes starting insulin. Secondary objectives: Investigate the association of demographics and clinical factors with SH incidence.

Methods: Integrated trial database data were obtained for 3 randomized controlled trials that included insulin-naïve people with type 2 diabetes initiating basal (insulin glargine) versus biphasic (insulin lispro mixture) insulin.

Introduction: The objective of this study was to assess basal insulin persistence, associated factors, and economic outcomes for insulin-naïve people with type 2 diabetes mellitus (T2DM) in Japan.

Methods: People aged at least 18 years with T2DM with first claim for basal insulin between May 2006 and April 2013 (index date), no insulin use before index date, and continuous insurance coverage for 6 months before (baseline) and 12 months after index date were selected from the Japan Medical Center Database. On the basis of whether there were at least 30-day gaps in basal insulin treatment, patients were classified as continuers (no gap), interrupters (at least one prescription after gap), and discontinuers (no prescription after gap).

Objective: To assess basal insulin persistence, associated factors, and economic outcomes for insulin-naïve people with type 2 diabetes mellitus (T2DM) in the US.

Research Design And Methods: People aged ≥18 years diagnosed with T2DM initiating basal insulin between April 2006 and March 2012 (index date), no prior insulin use, and continuous insurance coverage for 6 months before (baseline) and 24 months after index date (follow-up period) were selected using de-identified administrative claims data in the US. Based on whether there were ≥30 day gaps in basal insulin use in the first year post-index, patients were classified as continuers (no gap), interrupters (≥1 prescription after gap), and discontinuers (no prescription after gap).
