- Background and aims: Multiple daily insulin injections are an integral part of life for patients with type 1 diabetes (T1D). Moreover, patients’ schedules can change from day-to-day, further complicating T1D management. This study aimed to analyze daily injection patterns for patients with T1D, thereby providing insights into patients’ behaviour.Materials and methods: This post hoc observational study included children and adults with T1D from Sweden using NovoPen®6with bolus insulin (primarily insulin aspart) and/or basal insulin (primarily insulin degludec). Injection data were uploaded via the Glooko® cloud system. Daily bolus and basal injection timing profiles were documented, weighting each dose relative to the total daily dose. The time difference between two consecutive basal insulin injections was used to evaluate basal timing variation.Results: Overall, 159 adults and 47 children were included in the analysis, with a total of 38678 days of bolus injections and 17869 days of basal injections. The mean bolus daily injection profile displayed peaks at typical mealtimes, but substantial variation was observed both across patients and between adults and children (Figure 1). In those receiving insulin degludec, the timing of consecutive basal injections differed by more than 6 hr in approximately 9% of the injections for adults and 7% of those for children.Conclusion: These real-world data provide a unique insight into the everyday bolus and basal adherence of paediatric and adult patients with T1D. Furthermore, the results illustrate the flexibility needed for basal injections to enable optimal management of T1D.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background and aims: Randomised controlled trials and observational studies have shown lower risk of hypoglycemia in patients with type 1-diabetes (T1D) and type 2-diabetes (T2D) on treatment with insulinde gludec (IDeg) vs insulin glargine 100 units/mL (IGlar). This study assessed cost-effectiveness (C/E) of IDeg vs insulin treatment before switch to IDeg in a Swedish real-world setting in people with T1D and T2D.Materials and methods: ReFLeCT is a prospective, observational study in T1D (n=566) and T2D (n=611) in seven European countries and comprised a four-week baseline period (pre-switch basal insulin) and a 12-month follow-up period (IDeg). Data from ReFLeCT was used to assess C/E of IDeg compared with basal insulin treatment prior to switching to IDeg. Basal insulin unit costs were weighted to represent the basal insulin present at baseline (T1D: IGlar 63.8%, Insulin detemir (IDet) 22.7%, other/missing 13.5%. T2D: IGlar 59.1%, IDet 20.8%, other/missing 20.1%). The Swedish original IGlar price was used as base case. IGlar biosimilar price was used in a sensitivity analysis. Where information on basal insulin at baseline was missing, the lowest basal insulin price (insulin NPH) was used as a conservative approach. C/E was analysed over a 1-year time horizon from a Swedish societal perspective (price level 2019). Only differences with p<0.05 were included in the analysis.Results: Basal and bolus insulin doses at baseline were 25.0 IU and 27.3 IU (T1D) and 37.5 IU and 24.4 IU (T2D). At 12 months estimated basal and bolus insulin dose ratios were 0.91 (95% C.I. 0.83-0.91) and 0.87 (0.83-0.91) for T1D and 0.98 (0.95-1.01) and 0.96 (0.94-1.01) for T2D. For T1D riskratios (RR) for non-severe daytime hypoglycaemia was 0.85 (0.78-0.93), non-severe nocturnal hypoglycaemia 0.63 (0.52-0.76) and severe hypoglycaemia 0.28 (0.14-0.56). Corresponding RR for T2D were 0.56 (0.46-0.69), 0.38 (0.22-0.64) and 2.87 (0.33-24.65). In T1D IDeg was cost-saving compared to previous basal therapy (Table 1). In T2D, IDeg was highly cost-effective, with a cost per quality-adjusted life-year (QALY) of SEK 15,000-24,000 (Table 1). A treatment is considered cost-effective in Sweden if cost/QALY is below SEK 500,000. Sensitivity analyses showed that the results were robust to changes in efficacy and cost parameters in both T1D and T2D.Conclusion: In this C/E-analysis, treatment with IDeg was cost-saving (T1D) or highly cost-effective (T2D) relative to the treatment used before switch in a Swedish setting after one year. C/E of IDeg in clinical practice is driven by lower insulin doses (T1D) and reduced risk of hypoglycaemia (T1D and T2D).

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: The Europe-based, prospective, observational ReFLeCT study recently showed that switching to the ultralong-acting basal insulin analogue degludec (IDeg) was associated with improved glycemic control and reductions in hypoglycemic events versus previous basal insulin therapies in patients with type 1 (T1D) or type 2 diabetes (T2D). The present analysis aimed to assess the impact of thesefindings on long-term cost-effectiveness outcomes in the Swedish setting.Methods: Cost-effectiveness was evaluated separately in patients with T1D and T2D over a 50-year time horizon using the IQVIA CORE Diabetes Model (version 9.0). Patients were assumed to receive IDeg or continue previous insulin therapy (with or without bolus insulin) for 5 years, before all patients intensified to insulin degludec plus bolus insulin for the remainder of their lifetimes. Baseline cohort characteristics were sourced from ReFLeCT where possible. Treatment effects on initiation of IDeg were based on data from ReFLeCT. Costs were estimated from a Swedish societal perspective and expressed in 2018 Swedish krona (SEK).Results: IDeg was associated with improvements in quality-adjusted life expectancy of 0.14 and 0.07 quality-adjusted life years versus continuation of previous insulin therapy in patients with T1D and T2D, respectively, resulting from improved glycemic control and fewer hypoglycemic events. Combined direct and indirect costs were estimated to be SEK 137,020 and SEK 2,009 lower for insulin degludec versus previous insulin therapy in patients with T1D and T2D, respectively, with higher treatment costs offset by cos tsavings from avoidance of diabetes-related complications. IDeg was therefore considered dominant versus continuation of previous insulin therapies for the treatment of both T1D and T2D.Conclusions: Based on real-world evidence, IDeg represents an effective and cost-saving treatment option versus other basal insulin therapies for patients with T1D and T2D in Sweden.
