- In-hospital mortality of high-risk pulmonary embolism: a nationwide population-based cohort study in Portugal from 2010 to 2018Publication . Calé, R.; Ascenção, Raquel; Bulhosa, C.; Pereira, Helder; Borges, Margarida; Costa, J.; Caldeira, DanielBackground: The mortality associated with high-risk pulmonary embolism (PE) is remarkably high, and reperfusion to unload right ventricle should be a priority. However, several registries report reperfusion underuse. In Portugal, epidemiological data about the incidence, rate of reperfusion and mortality of high-risk PE are not known. Methods: Nationwide population-based temporal trend study in the incidence and outcome of high-risk PE, who were admitted to hospitals of the National Health Service in Portugal between 2010 and 2018. High-risk PE was defined as patients with PE who developed cardiogenic shock or cardiac arrest. International Classification of Diseases (ICD), 9th and 10th revision, Clinical Modification codes, were used for data from the period between 2010 and 2016 (ICD-9-CM) and 2017-2018 (ICD-10-CM), respectively. The assessment focused on trends in the use of reperfusion treatment, which was defined by application of thrombolysis or pulmonary embolectomy. A comparison was made between the use or non-use of reperfusion therapy in order to examine trends in in-hospital mortality among high-risk PE cases. Results: From 2010 and 2018, there were 40.311 hospitalization episodes for PE in adult patients at hospitals of the National Health Service in mainland Portugal. There was a significant increase in the annual incidence of PE (41/100.000 inhabitants in 2010 to 46/100.000 in 2018; R2=0.582, p = 0.010). The average annual incidence was 45/100.000 inhabitants/year, with 2,7% of the PE episodes (1104) categorized as high-risk. The mortality rate associated with high-risk PE was high, although it has decreased over the years (74.2% in 2010 to 63.6% in 2018; R2=0.484; p = 0.022). Thrombolytic therapy was underused in high-risk PE, and its usage has not increased in recent years (17.3% in 2010 to 21.1% in 2018, R2=-0.127; p = 0.763). Surgical pulmonary embolectomy was used in 0.27% of cases, and there was no registry of catheter-directed thrombolysis. Patients with high-risk PE undergoing reperfusion therapy had lower in-hospital mortality compared to non-reperfused patients (OR=0.52; IC95% 0.38-0.70). Conclusion: In Portugal, between 2010 and 2018, very few patients with PE developed high-risk forms of the disease, but the mortality rate among those patients was high. The low reperfusion rate could be associated with high in-hospital mortality and highlights the need to implement advanced therapies, as an alternative to systemic thrombolysis.
- Os custos da insuficiência cardíaca em Portugal e a sua evolução previsível com o envelhecimento da populaçãoPublication . Gouveia, Miguel Rebordão de Almeida; Ascenção, Raquel; Fiorentino, Francesca; Costa, João; Broeiro-Gonçalves, Paula; Fonseca, Maria Cândida Faustino Gamito da; Borges, MargaridaIntroduction and Objectives: Heart failure (HF) is a growing public health problem. This study estimates the current and future costs of HF in mainland Portugal. Methods: Costs were estimated based on prevalence and from a societal perspective. The annual costs of HF included direct costs (resource consumption) and indirect costs (productivity losses). Estimates were mostly based on data from the Diagnosis-Related Groups database, real-world data from primary care, and the opinions of an expert panel. Costs were estimated for 2014 and, taking population aging into account, changes were forecast up to 2036. Results: Direct costs in 2014 were D 299 million (39% for hospitalizations, 24% for medicines, 17% for exams and tests, 16% for consultations, and the rest for other needs, including emergencies and long-term care). Indirect costs were D 106 million (16% for absenteeism and 84% for reduced employment). Between 2014 and 2036, due to demographic dynamics, total costs will increase from D 405 to D 503 million. Per capita costs are estimated to rise by 34%, which is higher than the increase in total costs (+24%), due to the expected reduction in the resident population. Conclusions: HF currently has a significant economic impact, representing around 2.6% of total public health expenditure, and this is expected to increase in the future. This should be taken into account by health policy makers, alerting them to the need for resource management in order to mitigate the impact of this disease.
- Costs and consequences of the Portuguese needle-exchange program in community pharmaciesPublication . Borges, Margarida; Gouveia, Miguel; Fiorentino, Francesca; Jesus, Gonçalo; Cary, Maria; Guerreiro, José Pedro; Costa, Suzete; Carneiro, António VazBackground: Needle-exchange programs (NEPs) reduce infections in people who inject drugs. This study assesses the impact community pharmacies have had in the Needle-Exchange Program in Portugal since 2015. Methods: Health gains were measured by the number of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections averted, which were estimated, in each scenario, based on a standard model in the literature, calibrated to national data. The costs per infection were taken from national literature; costs of manufacturing, logistics and incineration of injection materials were also considered. The results were presented as net costs (i.e., incremental costs of the program with community pharmacies less the costs of additional infections avoided). Results: Considering a 5-year horizon, the Needle Exchange Program with community pharmacies would account for a 6.8% (n = 25) and a 6.5% reduction (n = 22) of HCV and HIV infections, respectively. The present value of net savings generated by the participation of community pharmacies in the program was estimated at €2,073,347. The average discounted net benefit per syringe exchanged is €3.01, already taking into account a payment to community pharmacies per needle exchanged. Interpretation: We estimate that the participation of community pharmacies in the Needle Exchange Program will lead to a reduction of HIV and HCV infections and will generate over €2 million in savings for the health system. Conclusions: The intervention is estimated to generate better health outcomes at lower costs, contributing to improving the efficiency of the public health system in Portugal.
- Atherosclerosis in the primary health care setting: a real-word data studyPublication . Ascenção, Raquel; Alarcão, Joana; Araujo, Francisco; Costa, João; Fiorentino, Francesca; Gil, Victor; Gouveia, Miguel; Lourenço, Francisco; Mello e Silva, Alberto; Carneiro, António Vaz; Borges, MargaridaIntroduction and objectives: To characterize patients with atherosclerosis, a disease with a high socioeconomic impact, in the Lisbon and Tagus Valley Health Region. Methods: A cross-sectional observational study was carried out through the Lisbon and Tagus Valley Regional Health Administration primary health care database, extracting data on the clinical and demographic characteristics and resource use of adult primary health care users with atherosclerosis during 2016. Different criteria were used to define atherosclerosis (presence of clinical manifestations, atherothrombotic risk factors and/or consumption of drugs related to atherosclerosis). Comparisons between different subpopulations were performed using parametric tests. Results: A total of 318 692 users were identified, most of whom (n=224 845 users; 71%) had no recorded clinical manifestations. The subpopulation with clinical manifestations were older (72.0±11.5 vs. 71.3±11.0 years), with a higher proportion of men (58.0% vs. 45.9%), recorded hypertension (78.3% vs. 73.5%) and dyslipidemia (55.8% vs. 53.5%), and a lower proportion of recorded obesity (18.2% vs. 20.8%), compared to those without clinical manifestations (p<0.001). Mean blood pressure, LDL-C and glycated hemoglobin values were lower in the subpopulation with manifestations (142/74 vs. 146/76 mmHg, 101 vs. 108 mg/dl, and 6.80 vs. 6.84%, respectively; p<0.001). Each user with atherosclerosis attended 4.1±2.9 face-to-face medical consultations and underwent 8.6±10.0 laboratory test panels, with differences in subpopulations with and without clinical manifestations (4.4±3.2 vs. 4.0±2.8 and 8.3±10.3 vs. 8.7±9.8, respectively; p<0.001). Conclusions: About one in three adult primary health care users with atherosclerosis have clinical manifestations. The results suggest that control of cardiovascular risk factors is suboptimal in patients with atherosclerosis.
- Anticoagulation therapy in patients with post-operative atrial fibrillation: systematic review with meta-analysisPublication . Neves, Inês Antunes; Magalhaes, Andreia; Lima da Silva, Gustavo; Almeida, Ana G.; Borges, Margarida; Costa, João; Ferreira, Joaquim J; Pinto, Fausto J.; Caldeira, DanielBackground: Post-operative atrial fibrillation (POAF) is a relevant complication after surgery. Several studies have shown that POAF has important consequences for long-term morbidity and mortality, by increasing the risk of thromboembolic events. However, the use of oral anticoagulation (OAC) is not well established in this context. Methods: We searched MEDLINE, CENTRAL, PsycInfo and Web of Science for clinical trials and observational studies evaluating anticoagulation vs. no anticoagulation in patients with POAF (after cardiac or non-cardiac surgery). Data were screened and extracted by two independent reviewers. We performed a random- effects model to estimate the pooled odds ratio (OR) with 95% Confidence Intervals (CI), and heterogeneity was evaluated by I2 statistics. The outcomes of interest were all-cause mortality, thromboembolic events, and bleeding events. Results: Overall, 10 observational retrospective studies were included: 5 studies with 203,946 cardiac surgery POAF patients, and 5 studies with 29,566 patients with POAF after non-cardiac surgery. In cardiac surgery POAF, the OAC use was associated with lower risk of thromboembolic events (OR 0.68; 95%CI 0.47-0.96, I2 = 31%; 4 studies) and the bleeding risk was significantly increased (OR 4.30; 95%CI 3.69 to 5.02, 1 study). In non-cardiac surgery POAF, OAC did not significantly reduce the risk of thromboembolic events (OR 0.71, 95%CI 0.33-1.15; I2 = 79%; 5 studies) but was associated with increased risk of bleeding (OR 1.20, 95%CI 1.10-1.32, I2 = 0%; 3 studies). Mortality was not significantly reduced in both cardiac and non-cardiac surgery POAF. Conclusion: Oral anticoagulation was associated with a lower risk of thromboembolic events in patients with POAF following cardiac surgery but not in non-cardiac surgery. Bleeding risk was increased in both settings. The confidence on pooled results is at most low, and further data, namely randomized controlled trials are necessary to derive robust conclusions.
- The burden of atherosclerosis in PortugalPublication . Costa, João; Alarcão, Joana; Araujo, Francisco; Ascenção, Raquel; Caldeira, Daniel; Fiorentino, Francesca; Gil, Victor; Gouveia, Miguel; Lourenço, Francisco; Mello e Silva, Alberto; Sampaio, Filipa; Carneiro, António Vaz; Borges, MargaridaAims: 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 PortugalPublication . Silva Miguel, Luís; Soares, Mariana; Olivieri, Anamaria; Sampaio, Filipa; Lamotte, Mark; Shukla, Suramya; Conde, Vasco; Freitas, Paula; Costa, João; Borges, MargaridaBackground: 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.
- COVID-19 era in long-term cardiac rehabilitation programs: how did physical activity and sedentary time change compared to previous years?Publication . Pires, Madalena; Borges, Margarida; Pinto, R.; Aguiar-Ricardo, Inês; Cunha, Nelson; Alves Da Silva, P.; Liñan Pinto, Mariana; Guerreiro, Catarina Sousa; Pinto, Fausto J.; Santa-Clara, Helena; Abreu, AnaCardiovascular rehabilitation (CR) was one of the many areas negatively affected by the COVID-19 pandemic. A high number of cardiovascular disease (CVD) patients had their centre-based program suspended. Physical activity (PA) recommendations for CVD patients are well established and its benefits largely documented. However, few studies have objectively measured the PA of these patients throughout the years and specifically during the COVID-19 pandemic.
- The cost-saving switch from inhaled corticosteroid-containing treatments to dual bronchodilation : a two-country projection of epidemiological and economic burden in chronic obstructive pulmonary diseasePublication . Souliotis, Kyriakos; Miguel, Luís Lopes Madureira Silva; Hillas, Georgios; Borges, Margarida; Papageorgiou, Giannis; Viana, Diogo; Malhadeiro, Joao; Soulard, StéphanePurpose: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2018 recommendations support maintenance treatment with long-acting bronchodilators in most symptomatic patients with chronic obstructive pulmonary disease (COPD). While restricting the overuse of inhaled corticosteroids (ICS) may influence healthcare utilization required to treat inadvertent respiratory (exacerbations and pneumonia) and diabetes-related events, it may also change the total medication cost. This analysis was performed to estimate the 5-year budget impact of switching from ICS-containing treatment combinations to dual bronchodilation, in line with the recommendations. Methods: The model quantified the budget impact of treatment and healthcare resource utilization when COPD patients were anticipated to switch from ICS-containing treatments to dual bronchodilation. Three switch scenarios were calculated with increasing proportions of patients on dual long-acting bronchodilators, to the detriment of ICS-containing double and triple combinations. Clinical and cost input data were based on results from clinical trials and Greek and Portuguese healthcare cost databases. Results: Healthcare resource use to manage exacerbations, pneumonia and diabetes-related events were projected to increase between 2019 and 2023 in parallel with the growing COPD patient population and associated costs were estimated at 52–57% of the total disease cost in the Greek and Portuguese base case scenarios. Total cost savings between 21 and 112million EUR were projected when the proportion of patients on double and triple ICS-containing treatments was gradually reduced to 50% in scenario A, 20% in scenario B and 7% in scenario C. Sensitivity analyses showed that none of the model assumptions had a major impact on the projected savings. Conclusion: The alignment of COPD treatment with current recommendations may bring clinical benefits to patients, without substantial cost increases and even cost savings for payers.
- Atherosclerosis: the cost of illness in PortugalPublication . Costa, João; Alarcão, Joana; Amaral-Silva, Alexandre; Araujo, Francisco; Ascenção, Raquel; Caldeira, Daniel; Cardoso, Marta Ferreira; Correia, Manuel; Fiorentino, Francesca; Gavina, Cristina; Gil, Victor; Gouveia, Miguel; Lourenço, Francisco; Mello E Silva, Alberto; Pedro, Luís M; Morais, João; Carneiro, António Vaz; Veríssimo, Manuel Teixeira; Borges, MargaridaIntroduction and objectives: Cardiovascular disease is the leading cause of death in Portugal and atherosclerosis is the most common underlying pathophysiological process. The aim of this study was to quantify the economic impact of atherosclerosis in Portugal by estimating disease-related costs. Methods: Costs were estimated based on a prevalence approach and following a societal perspective. Three national epidemiological sources were used to estimate the prevalence of the main clinical manifestations of atherosclerosis. The annual costs of atherosclerosis included both direct costs (resource consumption) and indirect costs (impact on population productivity). These costs were estimated for 2016, based on data from the Hospital Morbidity Database, the health care database (SIARS) of the Regional Health Administration of Lisbon and Tagus Valley including real-world data from primary care, the 2014 National Health Interview Survey, and expert opinion. Results: The total cost of atherosclerosis in 2016 reached 1.9 billion euros (58% and 42% of which was direct and indirect costs, respectively). Most of the direct costs were associated with primary care (55%), followed by hospital outpatient care (27%) and hospitalizations (18%). Indirect costs were mainly driven by early exit from the labor force (91%). Conclusions: Atherosclerosis has a major economic impact, being responsible for health expenditure equivalent to 1% of Portuguese gross domestic product and 11% of current health expenditure in 2016.
