    Aims: This paper sought to estimate the burden of disease attributable to atherosclerosis in mainland Portugal in 2016. Methods and results: The burden of atherosclerosis was measured in disability-adjusted life years (DALY) following the latest 2010 Global Burden of Disease (GBD) methodology. DALYs were estimated as the sum of years of life lost (YLL) with years lived with disability (YLD). The following clinical manifestations of atherosclerosis were included: ischemic heart disease (IHD) (including acute myocardial infarction (AMI), stable angina, and ischemic heart failure (IHF)), ischemic cerebrovascular disease (ICVD) and peripheral arterial disease (PAD). YLL were estimated based on all-cause mortality data for the Portuguese population and mortality due to IHD, ICVD and PAD for the year 2016 sourced from national statistics. Standard life expectancy was sourced from the GBD study. YLD corresponded to the product of the number of prevalent cases by an average disability weight (DW) for all possible combinations of disease. Prevalence data for the different clinical manifestations of atherosclerosis were sourced from epidemiological studies. DW were sourced from the published literature. In 2016, 15,123 deaths were attributable to atherosclerosis, which corresponded to 14.3% of overall mortality in mainland Portugal. DALYs totaled 260,943, 75% due to premature death (196,438 YLL) and 25% due to disability (64,505 YLD). Conclusion: Atherosclerosis entails a high disease burden to society. A large part of this burden would be avoidable if evidence-based effective and cost-effective interventions targeting known risk factors, from prevention to treatment, were implemented.
  • Cost-effectiveness of Semaglutide 2.4 mg in chronic weight management in Portugal

    Background: Obesity and overweight are a significant public health concern. Subcutaneous semaglutide 2.4 mg injection is a glucagon-like peptide-1 (GLP-1) analogue approved by the European Medicines Agency as an adjunct to a reduced calorie diet and increased physical activity (diet and exercise, D&E) for the treatment obesity and overweight in the presence of at least one weight related comorbidity. This study aimed to assess the cost-effectiveness of semaglutide 2.4 mg in combination with D&E compared to D&E alone for the Portuguese setting. Methods: Analysis were conducted using the Core Obesity Model (COM) version 18, a Markov state transition cohort model, to predict the health outcomes and costs of weight related complications based on changes in surrogate endpoints. Efficacy and safety data were sourced from the STEP trials (Body Mass Index, systolic blood pressure and glycemic status) from a cohort of adults aged on average 48 years with obesity (BMI ≥ 30 kg/m2) and ≥ 1 obesity-related comorbidities, over a time horizon of 40 years. Costs were estimated from the perspective of the Portuguese National Health Service. Sensitivity analyses were conducted to test the robustness of results across a range of assumptions. Results: On a patient level, Semaglutide 2.4 mg in addition to D&E compared to D&E alone, improved QALYs by 0.098 and yielded higher costs by 1,325 EUR over a 40-year time horizon, with an ICER of 13,459 EUR per QALY gained and 100% probability of cost-effectiveness at the given WTP. Semaglutide 2.4 mg remained cost-effective across all different scenarios and sensitivity analysis at a WTP of 20,000 EUR per QALY. Among the subpopulations examined, Semaglutide 2.4 mg yielded ICERs of 18,459 EUR for patients with BMI ≥ 30 kg/m2 and of 22,657 EUR for patients with BMI ≥ 35 kg/m2. Conclusions: Semaglutide 2.4 mg was cost-effective compared to D&E alone for patients with obesity (BMI ≥ 30 kg/m2) and weight related comorbidities in Portugal, over a 40-year time horizon.
