Burden of established cardiovascular disease in people with type 2 diabetes and matched controls: Hospital-based care, days absent from work, costs and mortality.

AIMS: To assess hospital-based care, work absence, associated costs, and mortality in patients with type 2 diabetes with and without established cardiovascular disease (eCVD) compared to matched controls. MATERIALS AND METHODS: In a population-based cohort study, we analysed individual-level data from national health, social insurance and socio-economic registers for people diagnosed with type 2 diabetes before age 70 years and controls (5:1) in Sweden. Regression analysis was used to attribute costs and days absent due to eCVD. Mortality was analysed using Cox proportional hazard regression, stratified by birth year and adjusted for sex and education. RESULTS: Thirty percent (n = 136 135 of 454 983) of people with type 2 diabetes had ≥1 person-year with eCVD (women 24%; men 34%). The mean annual costs of hospital-based care for diabetes complications were EUR 2629 (95% confidence interval [CI] 2601-2657) of which EUR 2337 (95% CI 2309-2365) were attributed to eCVD (89%). The most costly person-years (10th percentile) were observed in a broad subgroup, 42% of people with type 2 diabetes and eCVD. People with type 2 diabetes had on average 146 days absent (95% CI 145-147) per year, of which 68 days (47%; 95% CI 67-70) were attributed to eCVD. The mortality hazard ratio for type 2 diabetes with eCVD was 4.63 (95%CI 4.58-4.68) and without eCVD was 1.86 (95% CI 1.84-1.88) compared to controls without eCVD. CONCLUSION: The sizable burden of eCVD on both the individual with type 2 diabetes and society calls for efficient management in order to reduce the risks for those living with eCVD and to postpone its onset.

Model-based predictions on health benefits and budget impact of implementing empagliflozin in people with type 2 diabetes and established cardiovascular disease.

AIM: To perform a model-based analysis of the short- and long-term health benefits and costs of further increased implementation of empagliflozin for people with type 2 diabetes and established cardiovascular disease (eCVD) in Sweden. MATERIALS AND METHODS: The validated Institute for Health Economics Diabetes Cohort Model (IHE-DCM) was used to estimate health benefits and a 3-year budget impact, and lifetime costs per quality-adjusted life years (QALY) gained of increased implementation of adding empagliflozin to standard of care (SoC) for people with type 2 diabetes and eCVD in a Swedish setting. Scenarios with 100%/75%/50% implementation were explored. Analyses were based on 30 model cohorts with type 2 diabetes and eCVD (n = 131 412 at baseline) from national health data registers. Sensitivity analyses explored the robustness of results. RESULTS: Over 3 years, SoC with empagliflozin (100% implementation) versus SoC before empagliflozin resulted in 7700 total life years gained and reductions in cumulative incidence of cardiovascular deaths by 30% and heart failures by 28%. Annual costs increased by 15% from higher treatment costs and increased survival. Half of these benefits and costs are not yet reached with current implementation below 50%. SoC with empagliflozin yielded 0.37 QALYs per person, with an incremental cost-effectiveness ratio of 16 000 EUR per QALY versus SoC before empagliflozin. CONCLUSIONS: Model simulations using real-world data and trial treatment effects indicated that a broader implementation of empagliflozin, in line with current guidelines for treatment of people with type 2 diabetes and eCVD, would lead to further benefits even from a short-term perspective.

Implementation of Empagliflozin in Patients with Diabetes Mellitus Type 2 and Established Cardiovascular Disease: Estimation of 5-Year Survival and Costs in Sweden.

INTRODUCTION: Cardiovascular disease (CVD) affects approximately 30% of patients with diabetes mellitus type 2 (T2D) and leads to increased morbidity, decreased survival and increased healthcare utilization. The aim of this study was to estimate the impact of treating these patients with the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin on survival and healthcare utilization. METHODS: Actual survival and healthcare utilization data from a 5-year retrospective cohort study on patients with T2D and CVD in the Region of Östergötland, Sweden were used as a starting point. Actual data were adjusted in accordance with risk reductions for mortality and CV events related to empagliflozin treatment as reported in the EMPA-REG OUTCOME study. RESULTS: Applying the risk reductions related to empagliflozin treatment on the cohort of patients with T2D and CVD in Östergötland resulted in an increase in 5-year survival of 96 days per patient and reduced costs for healthcare and drugs other than empagliflozin. Including the cost of empagliflozin, treatment led to an increased net cost per patient of approximately SEK 18,000 over 5 years. CONCLUSION: Empagliflozin treatment would reduce mortality and healthcare utilization in the patient group. The treatment strategy should be considered cost-effective, supporting a broad implementation of empagliflozin for patients with T2D and established CVD, in line with current national and international guidelines.

Disease Burden and Healthcare Costs for T2D Patients With and Without Established Cardiovascular Disease in Sweden: A Retrospective Cohort Study.

INTRODUCTION: Type 2 diabetes (T2D) is a complex chronic disease with an increasing prevalence worldwide. It is commonly associated with complications, such as cardiovascular disease (CVD). Patients with both T2D and established CVD are exposed to increased risk of further cardiovascular events, which means increased healthcare costs and impairments to quality of life and survival. To determine the added burden of CVD for T2D patients, we have analyzed the consumption and costs of healthcare and mortality in two T2D patient cohorts, with and without established CVD, respectively, during a 5-year follow-up in a Swedish region. METHODS: Patients with T2D on 1 January 2012 were identified using the administrative database of Region Östergötland and the Swedish National Diabetes Register. Established CVD was defined as the presence of a CVD-related healthcare visit in the period 2002-2011. Identified T2D patients were then followed retrospectively for 5 years (2012-2016) and data collected on utilization of healthcare resources, healthcare costs, and survival. Data pertinent to the study were retrieved from regional databases and national registries. RESULTS: On the index date (1 January 2012) there were 19,731 patients with T2D (prevalence 4.5%) in Region Östergötland, of whom 5490 had established CVD. Those patients with established CVD were older, more often men, and had longer diabetes duration and worse kidney function than those without. Compared to T2D patients without CVD, those with CVD had a significantly higher healthcare consumption, experienced higher costs, and had lower survival during the follow-up. CONCLUSION: This study confirms that established CVD is common among patients with T2D (approximately 30%). Established CVD has negative effects on the utilization of healthcare resources, healthcare costs, and mortality. It is therefore very important to improve the treatment strategy of this patient group.
