- Background and aims: The prevalence of diabetes has increased rapidly over the last decades worldwide. The risk of complications and medical consequences is well known and identified as key driver of costs. Less evidence on the impact of individual diabetic complications on the societal burden is available. The objective was to analyse costs of hospital-based health care and work absence related to individual macrovascular and microvascular complications of type 2 diabetes in Sweden in 2016.Materials and methods: The study used data from a Swedish retrospective observational database cross-linking 20 years of individual-level data (1997-2016) from national population-based health, social insurance and socio-economic registers for 392,200 people with type 2 diabetes and matched controls (5:1). Diabetes status and presence of 19 types of complications were derived from years 1997-2016 while the costs of hospital-based care and of production loss due to diabetes complications were estimated for 2016. Regression analysis was used for comparison to controls, to attribute production loss to individual complications, and to account for joint presence of complications.Results: Complications are prevalent and patterns complex in type 2 diabetes (Fig. 1). Use of hospital care for complications was higher compared to controls: 86,104 vs 24,608 outpatient visits per 100,000 persons and 9,894 vs 2,546 inpatient admissions per 100,000 persons (p<0.001) in 2016. 26% vs 12% had ≥1 hospital contact. The corresponding total costs of hospital-based care fo rcomplications were EUR 91,875 vs EUR 23,222 per 100 persons (p<0.001) and 75% were directly attributed to diabetes (EUR 689/person). Regression analyses distributed the costs of days absent from work across diabetes complications, basic type 2 diabetes effect and unattributed causes: diabetes complications amounted to EUR 2,165/person in 2016. Key drivers of costs of production loss were macrovascular complications angina pectoris, heart failure and stroke, and microvascular complications eye disease including retinopathy, kidney disease and neuropathy. Early mortality in working ages cost additional EUR 579/person and medications used in risk-factor treatment amounted to EUR 418/person.Conclusion: The economic burden of complications in type 2 diabetes is substantial. Costs of productivity loss in this study were found to be greater than those of hospital-based care highlighting the need for considering treatment consequences in a societal perspective in research and policy.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background and aims: The development and application of digital technologies to healthcare is a key component in meeting the increasing demand from patients for chronic disease management. Healthcare payers need evidence to support value-based decisions on new technologies. Smart insulin pens record the timing and dose of insulin, and data can integrate with continuous glucose monitoring (CGM) to improve diabetes self-management. The present analysis assessed the cost-effectiveness of introducing a smart insulin pen from a Swedish public healthcare payer perspective.Materials andmethods: The IQVIA CORE DiabetesModel was used to project clinical outcomes and healthcare costs (2018 Swedish krona [SEK]) over patients’ lifetimes in a Swedish type 1 diabetes (T1D) population. The model projected the development of complications, mortality, HbA1c, hypoglycaemia and insulin dosing to estimate cost effectiveness. Clinical model inputs were informed by an observational study of the introduction of an NFC-enabled smart insulin pen (NovoPen® 6) in 94 adults with T1D receiving basal-bolus insulin and using CGM. Smar tinsulin pen use (median follow up 7 months) was associated with an additional 1.89 h/day time in range (TIR 3.9-10.0 mmol/L [70-180 mg/dL]) compared with baseline. Change in TIR was converted to change in HbA1c using a published regression equation to allow long-term outcomes to be modelled based on published risk equations. Additional TIR with the smart insulin pen translated to a 0.62% (6.8 mmol/mol) HbA1c reduction and there were 33 fewer CGM-documented non-severe hypoglycaemic events/patient/year (≥15 min <3.0 mmol/L [54 mg/dL]) relative to baseline. Baseline characteristics were taken from the study cohort or, if unavailable, adults with T1D from the Swedish National Diabetes Register. Future costs and clinical benefits were discounted at 3% annually. Costs were converted to Euros (EUR) using a 0.091 SEK exchange rate.Results: Over patients’ lifetimes, smart insulin pen use was associated with improved mean discounted quality-adjusted life expectancy (1.13 quality-adjusted life years) and cost savings (EUR11,091) vs standard care. Improvements in quality-adjusted life expectancy were driven by a lower frequency and delayed onset of complications predicted with the smart insulin pen relative to standard care. Higher treatment costs (due to the higher bolus insulin dose) with the smart insulin pen were offset by the lower cost of complications compared with standard care (Fig).Conclusion: In this long-term modelling analysis, lifelong use of a smart insulin pen improved clinical outcomes at a lower cost relative to standard care in a T1D population, suggesting that the smart insulin pen represents an efficient use of Swedish public healthcare resources in this patient population.

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.

- Data from a 20-week trial comparing insulin detemir and neutral protamine Hagedorn (NPH) insulin in insulin-naïve people with type 2 diabetes were analyzed using willingness-to-pay (WTP) data, a proxy for patient preference. The advantages of insulin detemir relative to NPH insulin with respect to a lower hypoglycemia rate and less weight gain were associated with a value of €27.87 per month.

- Objective: The purpose of this study was to investigate the preferences of people with diabetes for liraglutide vs other glucose lowering drugs, based on outcomes of clinical trials.Methods: Willingness to pay (WTP) for diabetes drug treatment was assessed by combining results from a recent WTP study with analysis of results from the Liraglutide Effect and Action in Diabetes (LEAD) programme. The LEAD programme included six randomised clinical trials with 3967 participants analysing efficacy and safety of liraglutide 1.2 mg (LEAD 1-6 trials), rosiglitazone (LEAD 1 trial), glimepiride (LEAD 2-3 trials), insulin glargine (LEAD 5 trial), and exenatide (LEAD 6 trial). The WTP survey used discrete choice experimental (DCE) methodology to evaluate the convenience and clinical effects of glucose lowering treatments.Results: People with type 2 diabetes were prepared to pay an extra €2.64/day for liraglutide compared with rosiglitazone, an extra €1.94/day compared with glimepiride, an extra €3.36/day compared with insulin glargine, and an extra €0.81/day compared with exenatide. Weight loss was the largest component of WTP for liraglutide compared with rosiglitazone, glimepiride, and insulin glargine. Differences in the administration of the two drugs was the largest component of WTP for liraglutide (once daily anytime) compared with exenatide (twice daily with meals). A limitation of the study was that it was based on six clinical trials where liraglutide was the test drug, but each trial had a different comparator, therefore the clinical effects of liraglutide were much better documented than the comparators.Conclusions: WTP analyses of the clinical results from the LEAD programme suggested that participants with type 2 diabetes were willing to pay appreciably more for liraglutide than other glucose lowering treatments. This was driven by the relative advantage of weight loss compared with rosiglitazone, glimepiride, and insulin glargine, and administration frequency compared with exenatide.

- Purpose: The increased normal tissue tolerance for FLASH radiotherapy (FLASH-RT), as compared to conventional radiotherapy, was first observed in ultra-high dose rate electron beams. Initial clinical trials in companion animals have revealed a high risk of developing osteoradionecrosis following high-dose single-fraction electron FLASH-RT, which may be related to inhomogeneities in the dose distribution. In the current study, we aim to evaluate the possibilities of intensity-modulated electron FLASH-RT in a clinical setting to ensure a homogeneous dose distribution in future veterinary and human clinical trials. Methods: Our beam model in the treatment planning system electronRT (.decimal, LLC, Sanford, FL, USA) was based on a 10-MeV electron beam from a clinical linear accelerator used to treat veterinary patients with FLASH-RT in a clinical setting. In electronRT, the beam can be intensity-modulated using tungsten island blocks in the electron block cutout, and range-modulated using a customized bolus with variable thickness. Modulations were first validated in a heterogeneous phantom by comparing measured and calculated dose distributions. To evaluate the impact of intensity modulation in superficial single-fraction FLASH-RT, a treatment planning study was conducted, including eight canine cancer patient cases with simulated tumors in the head-and-neck region. For each case, treatment plans with and without intensity modulation were created for a uniform bolus and a range-modulating bolus. Treatment plans were evaluated using a target dose homogeneity index (HI), a conformity index (CI), the near-maximum dose outside the target ((Figure presented.)), and the near-minimum dose to the target ((Figure presented.)). Results: By adding intensity modulation to plans with a uniform bolus, the HI could be improved (p = 0.017). The combination of a range-modulating bolus and intensity modulation provided a further significant improvement of the HI as compared to using intensity modulation in combination with a uniform bolus (p = 0.036). The range-modulating bolus also improved the CI compared to using a uniform bolus, both with an open beam (p = 0.046) and with intensity modulation (p = 0.018), as well as increased the (Figure presented.) (p = 0.036 with open beam and p = 0.05 with intensity modulation) and reduced the median (Figure presented.) (not significant). Conclusions: By using intensity-modulated electron FLASH-RT in combination with range-modulating bolus, the target dose homogeneity and conformity in canine patients with simulated tumors in complex areas in the head-and-neck region could be improved. By utilizing this technique, we hope to decrease the dose outside the target volume and avoid hot spots in future clinical electron FLASH-RT studies, thereby reducing the risk of radiation-induced toxicity.
