Abstract
BACKGROUND Bempedoic acid is a novel adenosine triphosphate citrate lyase inhibitor shown to reduce low density lipoprotein cholesterol when used as an adjunct lipid-lowering therapy in patients with high cardiovascular disease (CVD) risk. OBJECTIVE Our analysis aimed to determine the price at which bempedoic acid would be cost-effective from the Australian health care perspective. METHODS A Markov model was designed using data from the Cholesterol Lowering via Bempedoic Acid, an ACL-Inhibiting Regimen (CLEAR) Harmony trial, to model the clinical outcomes and costs of 1000 patients treated with bempedoic acid over a lifetime horizon. Relevant health states were "Alive with CVD," "Alive with recurrent CVD," and "Dead." With annual cycles, patients were at risk of a nonfatal myocardial infarction, coronary revascularization, and death from CVD or non-CVD causes. Costs and utilities were obtained from published sources. Outcomes of interest were the incremental cost-effectiveness ratios in terms of cost per quality-adjusted life year (QALY) gained and cost per year of life saved. Outcomes were discounted at 5% per annum. RESULTS Among 1000 individuals, bempedoic acid in addition to statin therapy was estimated to save 122 (discounted) years of life and 103 (discounted) QALYs compared with statin therapy alone. At an acquisition cost of AU$584.40 per year (USD$397.01), bempedoic acid would be considered cost-effective within the Australian setting, with an incremental cost-effectiveness ratio of AU$49,890 per QALY gained (USD$33,893) and AU$42,433 per year of life saved (USD$28,827). CONCLUSIONS Bempedoic acid may be cost-effective within the Australian health care setting at an annual acquisition price less than $600.

Abstract
BACKGROUND Inclisiran inhibits hepatic synthesis of proprotein convertase subtilisin-kexin type 9 (PCSK9). The comparison of inclisiran with statin versus statin alone in the ORION-10 trial demonstrated significant reductions in low-density lipoprotein cholesterol (LDL-C). Our study explored whether the use of inclisiran with statin versus statin alone for secondary prevention of cardiovascular events is cost effective from the Australian healthcare perspective, based on the price of currently available PCSK9 inhibitors. METHODS A Markov model was developed based on the ORION-10 trial to model outcomes and costs incurred by patients over a lifetime analysis. The three health states were 'alive with cardiovascular disease (CVD)', 'alive with recurrent CVD', and 'dead'. Cost and utilities were estimated from published sources. The cost of inclisiran was estimated from the annual cost of evolocumab, a PCSK9 inhibitor currently available in Australia (AU$6334, based on 2020 data). Outcomes of interest were incremental cost-effectiveness ratios (ICERs) in terms of cost per quality-adjusted life-year (QALY) and cost per year of life saved (YoLS). All costs, QALYs and YoLS were discounted at 5% per annum in line with Australian standards. RESULTS Among 1000 subjects followed-up over a lifetime analysis, inclisiran with statin compared with statin alone prevented 235 non-fatal myocardial infarctions (NFMIs; 151 NFMI and 84 repeat NFMI cases) and 114 coronary revascularisation cases, and increased years of life by 0.549 (discounted) and QALYs by 0.468 (discounted). At an annual price of AU$6334, the net marginal cost was AU$58,965 per person. The above values equated to ICERs of AU$107,402 per YoLS and AU$125,732 per QALY gained. Assuming a willingness-to-pay threshold of AU$50,000, inclisiran would have to be priced 60% lower than other available PCSK9 inhibitors to be considered cost effective. CONCLUSIONS As an adjunct therapy to statin treatment in those who have persistently elevated LDL-C despite optimal statin therapy, inclisiran is effective in reducing cardiovascular events in patients with atherosclerotic CVD. Inclisiran is not cost effective from the Australian healthcare perspective, assuming acquisition costs of current PCSK9 inhibitors. The cost of inclisiran would have to be 60% lower than that of evolocumab.

Abstract
AIMS Percutaneous coronary intervention reduces mortality in acute coronary syndrome patients but the cost-utility of increasing its use in elderly acute coronary syndrome patients is unknown. METHODS We assessed the efficiency of increased percutaneous coronary intervention use compared to current practice in patients aged ≥75 years admitted for acute coronary syndrome in France, Germany, Greece, Italy, Portugal and Spain with a semi-Markov state transition model. In-hospital mortality reduction estimates by percutaneous coronary intervention use and costs were derived from the EUROpean Treatment & Reduction of Acute Coronary Syndromes cost analysis EU project (n = 28,600). Risk of recurrence and out-of-hospital all-cause mortality were obtained from the Information System for the Development of Research in Primary Care (SIDIAP) database from North-Eastern Spain (n = 55,564). In-hospital mortality was modelled using stratified propensity score analysis. The 8-year acute coronary syndrome recurrence risk and out-of-hospital mortality were estimated with a multistate survival model. The scenarios analysed were to increase percutaneous coronary intervention use among patients with the highest, moderate and lowest probability of receiving percutaneous coronary intervention based on the propensity score analysis. RESULTS France, Greece and Portugal showed similar total costs/1000 individuals (7.29-11.05 m €); while in Germany, Italy and Spain, costs were higher (13.53-22.57 m €). Incremental cost-utility ratios of providing percutaneous coronary intervention to all patients ranged from 2262.8 €/quality adjusted life year gained for German males to 6324.3 €/quality adjusted life year gained for Italian females. Increasing percutaneous coronary intervention use was cost-effective at a willingness-to-pay threshold of 10,000 €/quality adjusted life year gained for all scenarios in the six countries, in males and females. CONCLUSION Compared to current clinical practice, broadening percutaneous coronary intervention use in elderly acute coronary syndrome patients would be cost-effective across different healthcare systems in Europe, regardless of the selected strategy.

Abstract
BACKGROUND Thromboprophylaxis can reduce the risk of venous thromboembolism (VTE) during lower-limb immobilisation, but it is unclear whether or not this translates into meaningful health benefit, justifies the risk of bleeding or is cost-effective. Risk assessment models (RAMs) could select higher-risk individuals for thromboprophylaxis. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of different strategies for providing thromboprophylaxis to people with lower-limb immobilisation caused by injury and to identify priorities for future research. DATA SOURCES Ten electronic databases and research registers (MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Review of Effects, the Cochrane Central Register of Controlled Trials, Health Technology Assessment database, NHS Economic Evaluation Database, Science Citation Index Expanded, ClinicalTrials.gov and the International Clinical Trials Registry Platform) were searched from inception to May 2017, and this was supplemented by hand-searching reference lists and contacting experts in the field. REVIEW METHODS Systematic reviews were undertaken to determine the effectiveness of pharmacological thromboprophylaxis in lower-limb immobilisation and to identify any study of risk factors or RAMs for VTE in lower-limb immobilisation. Study quality was assessed using appropriate tools. A network meta-analysis was undertaken for each outcome in the effectiveness review and the results of risk-prediction studies were presented descriptively. A modified Delphi survey was undertaken to identify risk predictors supported by expert consensus. Decision-analytic modelling was used to estimate the incremental cost per quality-adjusted life-year (QALY) gained of different thromboprophylaxis strategies from the perspectives of the NHS and Personal Social Services. RESULTS Data from 6857 participants across 13 trials were included in the meta-analysis. Thromboprophylaxis with low-molecular-weight heparin reduced the risk of any VTE [odds ratio (OR) 0.52, 95% credible interval (CrI) 0.37 to 0.71], clinically detected deep-vein thrombosis (DVT) (OR 0.40, 95% CrI 0.12 to 0.99) and pulmonary embolism (PE) (OR 0.17, 95% CrI 0.01 to 0.88). Thromboprophylaxis with fondaparinux (Arixtra®, Aspen Pharma Trading Ltd, Dublin, Ireland) reduced the risk of any VTE (OR 0.13, 95% CrI 0.05 to 0.30) and clinically detected DVT (OR 0.10, 95% CrI 0.01 to 0.94), but the effect on PE was inconclusive (OR 0.47, 95% CrI 0.01 to 9.54). Estimates of the risk of major bleeding with thromboprophylaxis were inconclusive owing to the small numbers of events. Fifteen studies of risk factors were identified, but only age (ORs 1.05 to 3.48), and injury type were consistently associated with VTE. Six studies of RAMs were identified, but only two reported prognostic accuracy data for VTE, based on small numbers of patients. Expert consensus was achieved for 13 risk predictors in lower-limb immobilisation due to injury. Modelling showed that thromboprophylaxis for all is effective (0.015 QALY gain, 95% CrI 0.004 to 0.029 QALYs) with a cost-effectiveness of £13,524 per QALY, compared with thromboprophylaxis for none. If risk-based strategies are included, it is potentially more cost-effective to limit thromboprophylaxis to patients with a Leiden thrombosis risk in plaster (cast) [L-TRiP(cast)] score of ≥ 9 (£20,000 per QALY threshold) or ≥ 8 (£30,000 per QALY threshold). An optimal threshold on the L-TRiP(cast) receiver operating characteristic curve would have sensitivity of 84-89% and specificity of 46-55%. LIMITATIONS Estimates of RAM prognostic accuracy are based on weak evidence. People at risk of bleeding were excluded from trials and, by implication, from modelling. CONCLUSIONS Thromboprophylaxis for lower-limb immobilisation due to injury is clinically effective and cost-effective compared with no thromboprophylaxis. Risk-based thromboprophylaxis is potentially optimal but the prognostic accuracy of existing RAMs is uncertain. FUTURE WORK Research is required to determine whether or not an appropriate RAM can accurately select higher-risk patients for thromboprophylaxis.

Abstract
Background Several large scale community-based cardiovascular disease prevention programs were initiated in the 80s, and one was the Västerbotten Intervention Programme, Sweden. As an initial step in 1985, a pilot study was introduced in the Norsjö municipality that combined individual disease prevention efforts among the middle-aged population with community-oriented health promotion activities. All citizens at 30, 40, 50, and 60 years of age were invited to a physical examination combined with a healthy dialogue at the local primary health care centre. Västerbotten Intervention Program is still running following the same lines and is now a part of the ordinary public health in the county. The purpose of this study is to estimate the costs of running Västerbotten Intervention Programme from 1990 to 2006, versus the health gains and savings reasonably attributable to the program during the same time period. Methods A previous study estimated the number of prevented deaths during the period 1990–2006 which can be attributed to the programme. We used this estimate and calculated the number of QALYs gained, as well as savings in resources due to prevented non-fatal cases during the time period 1990 to 2006. Costs for the programmes were based on previously published scientific articles as well as current cost data from the county council, who is responsible for the programme. Result The cost per QALY gained from a societal perspective is SEK 650 (Euro 68). From a health care sector perspective, the savings attributable to the VIP exceeded its costs. Conclusion Our analysis shows that Västerbotten Intervention Programme is extremely cost-effective in relation to the Swedish threshold value (SEK 500000 per QALY gained or Euro 53,000 per QALY gained). Other research has also shown a favorable effect of Västerbotten Intervention Programme on population health and the health gap. We therefore argue that all health care organizations, acting in settings reasonably similar to Sweden, have good incentive to implement programs like Västerbotten Intervention Programme.

Abstract
OBJECTIVES To estimate productivity loss and associated indirect costs in high-risk patients treated for hyperlipidemia who experience cardiovascular (CV) events. METHODS Retrospective population-based cohort study conducted using Swedish medical records linked to national registers. Patients were included based on prescriptions of lipid-lowering therapy between 1 January 2006 and 31 December 2011 and followed until 31 December 2012 for identification of CV events and estimation of work productivity loss (sick leave and disability pension) and indirect costs. Patients were stratified into two cohorts based on CV risk level: history of major cardiovascular disease (CVD) and coronary heart disease (CHD) risk equivalent. Propensity score matching was applied to compare patients with new events (cases) to patients without new events (controls). The incremental effect of CV events was estimated using a difference-in-differences design, comparing productivity loss among cases and controls during the year before and the year after the cases' event. RESULTS The incremental effect on indirect costs was largest in the CHD risk equivalent cohort (n = 2946) at €3119 (P value <0.01). The corresponding figure in the major CVD history cohort (n = 4508) was €2210 (P value <0.01). There was substantial variation in productivity loss depending on the type of event. Transient ischemic attack and revascularization had no significant effect on indirect costs. Myocardial infarction (€3465), unstable angina (€2733) and, most notably, ischemic stroke (€6784) yielded substantial incremental cost estimates (P values <0.01). CONCLUSIONS Indirect costs related to work productivity losses of CV events are substantial in Swedish high-risk patients treated for hyperlipidemia and vary considerably by type of event.

Abstract
INTRODUCTION People with cardiovascular disease (CVD) often require time off work to recover from illness or surgery; for example, following a myocardial infarction (MI) or stroke. These individuals incur income losses, work-related productivity is reduced for employers, and output is reduced for the wider economy. Productivity impacts to the economy also arise due to CVD-related mortality. Areas covered: A systematic literature review was conducted to identify and collate studies that report the magnitude of work-related productivity losses associated with CVD generally or specific cardiovascular (CV) events or conditions (coronary heart disease, MI, stroke, transient ischemic attack, angina, heart failure, peripheral artery disease, coronary revascularization). The search was conducted using Medline, Embase, the Cochrane Library, and Google to find studies published from January 2004 to January 2015. In total, 60 studies were identified, including 20 studies conducted in the USA, 25 studies conducted in Europe, and 18 studies conducted in other countries (three studies were conducted in multiple regions). The studies differed by the scope of losses assessed (absenteeism, presenteeism, early retirement, premature mortality) and CVD conditions/events included. Studies reported either average patient or population losses, and generally used a human capital rather than friction cost method. Outcomes were standardized and adjusted to 2015 US dollars where possible. Expert commentary: The review demonstrates that CVD imposes substantial morbidity- and mortality-related productivity costs. The studies identified in the review may be used to inform and populate societal economic evaluations in CVD, with the most appropriate source study being that most closely matching the context of the evaluation.

Abstract
OBJECTIVES The objective of this study was to analyse how hospitalisation after the age of 60 affected individuals' health-related quality of life (HRQoL). The main hypothesis was that a hospital admission in old age can be seen as a proxy of ill health and possibly as a health divider, separating life into a healthy and an unhealthy part. The extent to which this is true depends on which disease individuals face and how functional ability and HRQoL are affected. SETTINGS This was a longitudinal study, based on an older cohort of individuals who participated in the Stockholm Public Health Cohort (SPHC) survey in 2006; the survey took place in Stockholm, Sweden. Information regarding hospitalisations and deaths, which is available through Swedish administrative registers, was linked to the survey from the National Patient Register and Cause of Death Register. PARTICIPANTS 2101 individuals, 65+ years old at inclusion, with no previous hospitalisations at baseline (2006), were followed for 4 years until 2010 (end of follow-up). PRIMARY AND SECONDARY OUTCOME MEASURES HRQoL was assessed through a utility index derived from the EuroQol 5D questionnaire, at baseline and at 2010. The change in HRQoL after admission(s) to the hospital was estimated as the difference between the 2010 and 2006 levels using linear regression, also considering several covariates. RESULTS A single hospitalisation did not reduce individuals' HRQoL, either for men or women. On the other hand, multiple any-cause hospitalisations reduced HRQoL between 3.2% and 6.5%. When looking into hospitalisations for specific causes, such as hip fractures, a decrease in HRQoL was observed as well; however, conclusions regarding this were impeded by the small sample size. CONCLUSIONS Hospital admissions in old age may indicate a shift from a healthy life to a life of compromised health when considering their frequency and cause over a period of time.

Abstract
OBJECTIVES Untreated obstructive sleep apnea-hypopnea syndrome (OSAHS) is associated with excessive daytime sleepiness, increased risk of cardiovascular (CV) disease, and road traffic accidents (RTAs), which impact survival and health-related quality of life. This study, funded by the French National Authority for Health (HAS), aimed to assess the cost-effectiveness of different treatments (i.e., continuous positive airway pressure [CPAP], dental devices, lifestyle advice, and no treatment) in patients with mild-to-moderate OSAHS in France. METHODS A Markov model was developed to simulate the progression of two cohorts, stratified by CV risk, over a lifetime horizon. Daytime sleepiness and RTAs were taken into account for all patients while CV events were only considered for patients with high CV risk. RESULTS For patients with low CV risk, incremental cost-effectiveness ratio (ICER) of dental devices versus no treatment varied between 32,976 EUR (moderate OSAHS) and 45,579 EUR (mild OSAHS) per quality-adjusted life-year (QALY), and CPAP versus dental devices, above 256,000 EUR/QALY. For patients with high CV risk, CPAP was associated with a gain of 0.62 QALY compared with no treatment, resulting in an ICER of 10,128 EUR/QALY. CONCLUSION The analysis suggests that it is efficient to treat all OSAHS patients with high CV risk with CPAP and that dental devices are more efficient than CPAP for mild-to-moderate OSAHS with low CV risk. However, out-of-pocket costs are currently much higher for dental devices than for CPAP (i.e., 3,326 EUR versus 2,430 EUR) as orthodontic treatment is mainly non-refundable in France.

Abstract
BACKGROUND AND OBJECTIVE We recently showed that a pharmacist-led information technology-based intervention (PINCER) was significantly more effective in reducing medication errors in general practices than providing simple feedback on errors, with cost per error avoided at £79 (US$131). We aimed to estimate cost effectiveness of the PINCER intervention by combining effectiveness in error reduction and intervention costs with the effect of the individual errors on patient outcomes and healthcare costs, to estimate the effect on costs and QALYs. METHODS We developed Markov models for each of six medication errors targeted by PINCER. Clinical event probability, treatment pathway, resource use and costs were extracted from literature and costing tariffs. A composite probabilistic model combined patient-level error models with practice-level error rates and intervention costs from the trial. Cost per extra QALY and cost-effectiveness acceptability curves were generated from the perspective of NHS England, with a 5-year time horizon. RESULTS The PINCER intervention generated £2,679 less cost and 0.81 more QALYs per practice [incremental cost-effectiveness ratio (ICER): -£3,037 per QALY] in the deterministic analysis. In the probabilistic analysis, PINCER generated 0.001 extra QALYs per practice compared with simple feedback, at £4.20 less per practice. Despite this extremely small set of differences in costs and outcomes, PINCER dominated simple feedback with a mean ICER of -£3,936 (standard error £2,970). At a ceiling 'willingness-to-pay' of £20,000/QALY, PINCER reaches 59 % probability of being cost effective. CONCLUSIONS PINCER produced marginal health gain at slightly reduced overall cost. Results are uncertain due to the poor quality of data to inform the effect of avoiding errors.

Abstract
Cardiovascular disease (CVD) results in half of the non-communicable disease-related deaths worldwide. Rising treatment costs have increased the need for cost-utility models designed to compare the value of new and existing therapies. Cost-utility models require utilities, values representing the strength of preferences for various health states. This systematic literature review aimed to identify and evaluate utilities reported for stroke, myocardial infarction (MI) and angina. In total, 83 unique studies were identified that reported utilities for these events. Approximately two-thirds reported utility values for stroke, and most used the EuroQoL five dimension to derive utilities. Utility values were lower in patients who experienced cardiovascular (CV) events than in patients who did not. The utility estimates for each condition varied greatly, likely due to differences in assessment methodologies and patient populations. This variability must be considered when choosing values for cost-utility models. Comparisons among reported utilities are further complicated by inconsistent CV event definitions.

Abstract
The ATHENA clinical trial enrolled 4,628 patients in 37 countries and evaluated the efficacy of dronedarone 400 mg twice daily versus placebo for the prevention of cardiovascular hospitalisation or death from any cause in patients with paroxysmal or persistent atrial fibrillation or atrial flutter. The trial showed a statistically significant 24% reduction in the primary endpoint cardiovascular hospitalisations or all-cause death. In the current paper, parameters that drive the cost-effectiveness of dronedarone on top of standard therapy versus likely comparators, i.e. amiodarone, sotalol and flecainide, were investigated by means of a health economic model based on the ATHENA clinical trial. Dronedarone is cost-effective, and ICERs are low versus amiodarone with €5,340; €4,620; €3,850 and €5,630 per QALY gained for Canada, Italy, Sweden and Switzerland, respectively. The most significant driving factor for the cost-effectiveness of dronedarone is the increased survival rate for patients on dronedarone.

Abstract
BACKGROUND The first antiarrhythmic drug to demonstrate a reduced rate of cardiovascular hospitalization in atrial fibrillation/flutter (AF/AFL) patients was dronedarone in a placebo-controlled, double-blind, parallel arm Trial to assess the efficacy of dronedarone 400 mg bid for the prevention of cardiovascular Hospitalization or death from any cause in patiENts with Atrial fibrillation/atrial flutter (ATHENA trial). The potential cost-effectiveness of dronedarone in this patient population has not been reported in a US context. This study assesses the cost-effectiveness of dronedarone from a US health care payers' perspective. METHODS AND RESULTS ATHENA patient data were applied to a patient-level health state transition model. Probabilities of health state transitions were derived from ATHENA and published data. Associated costs used in the model (2010 values) were obtained from published sources when trial data were not available. The base-case model assumed that patients were treated with dronedarone for the duration of ATHENA (mean 21 months) and were followed over a lifetime. Cost-effectiveness, from the payers' perspective, was determined using a Monte Carlo microsimulation (1 million fictitious patients). Dronedarone plus standard care provided 0.13 life years gained (LYG), and 0.11 quality-adjusted life years (QALYs), over standard care alone; cost/QALY was $19,520 and cost/LYG was $16,930. Compared to lower risk patients, patients at higher risk of stroke (Congestive heart failure, history of Hypertension, Age ≥ 75 years, Diabetes mellitus, and past history of Stroke or transient ischemic attack (CHADS(2)) scores 3-6 versus 0) had a lower cost/QALY ($9580-$16,000 versus $26,450). Cost/QALY was highest in scenarios assuming lifetime dronedarone therapy, no cardiovascular mortality benefit, no cost associated with AF/AFL recurrence on standard care, and when discounting of 5% was compared with 0%. CONCLUSIONS By extrapolating the results of a large, multicenter, randomized clinical trial (ATHENA), this model suggests that dronedarone is a cost-effective treatment option for approved indications (paroxysmal/persistent AF/AFL) in the US.

Abstract
Background Although angiotensin receptor blockers have different receptor binding properties, no comparative randomized studies with cardiovascular event endpoints have been performed for this class of drugs. The aim of this study was to assess the long-term cost-effectiveness of candesartan (Atacand®) versus generic losartan in the primary preventive treatment of hypertension. Methods A decision-analytic model was developed to estimate costs and health outcomes over a patient’s lifetime. Data from a clinical registry study were used to estimate event rates for cardiovascular complications, such as myocardial infarction and heart failure. Costs and quality of life data were from published sources. Costs were in Swedish kronor and the outcome was quality-adjusted life-years (QALYs). Results Due to reduced rates of cardiovascular complications, candesartan was associated with a QALY gain and lower health care costs compared with generic losartan (0.053 QALYs gained and reduced costs of approximately 4700 Swedish kronor for women; and 0.057 QALYs gained and reduced costs of approximately 4250 Swedish kronor for men). This result was robust in several sensitivity analyses. Conclusion When modeling costs and health outcomes based on event rates for cardiovascular complications from a real-world registry study, candesartan appears to bring a QALY gain and a reduction in costs compared with generic losartan in the primary preventive treatment of hypertension in Sweden.

Abstract
BACKGROUND The economic evaluation of statins has undergone a development from risk-factor-based models to modeling of hard end points in clinical trials with a shift back to risk-factor models after increased confidence in their predictive power has now been established. At this point, we can look back on the historical economic data on simvastatin to see what lesson regarding reimbursement we can learn. METHODS Historical data on the usage and sales of simvastatin in Sweden were combined with published epidemiological and clinical data to calculate the social value of simvastatin to the present day and to make projection until projected until 2018. The distribution of the social surplus was calculated by taking the costs born by society and the producer of the drug into consideration. RESULTS The cost of simvastatin fell drastically following patent expiration, although the number of treated patients has continued to grow. Presently, the use of simvastatin is close to cost neutrality taking direct and indirect cost savings from reduced morbidity into account. However, the major part of the social surplus generated comes from the value of improved quality-adjusted survival. Of the social surplus generated, the producer appropriated 20-43% of the value during the on-patent period, a figure dropping to 1% following loss of exclusivity. The total producer surplus between 1987 and 2018 is 2-5% of the total social surplus. CONCLUSION Only a small part of the surplus value generated was appropriated by the producer. A regulatory and reimbursement approach that favors early market access and coverage with evidence development as opposed to long-term trials as a pre-requisite for launch is more attractive from both a company and social perspective.

Abstract
BACKGROUND/OBJECTIVES To predict the health economic consequences of modest reductions in the daily intake of salt (-1.0 g per day) and replacement of saturated fat (SFA, -1.0 energy percent (E%)) with polyunsaturated fat (PUFA, +1.0 E%) in the Finnish population aged 30-74 years. SUBJECTS/METHODS A Markov model with dynamic population structure was constructed to present the natural history of cardiovascular diseases (CVDs) based on the most current information about the age- and sex-specific cardiovascular risk factors, dietary habits and nutrient intake. To predict the undiscounted future health economic consequences of the reduction of dietary salt and SFA, the model results were extrapolated for the years 2010-2030 by replacing the baseline population in the year 2007 with the extrapolated populations from the official Finnish statistics. Finnish costs (€2009, societal perspective) and EQ-5D utilities were obtained from published references. RESULTS During the next 20 years, a population-wide intervention directed at salt intake and dietary fat quality could potentially lead to 8000-13,000 prevented CVD cases among the Finnish adults compared the situation in year 2007. In addition, the reduced incidence of CVDs could gain 26,000-45,000 quality-adjusted life years and save €150-225 million over the same time period. CONCLUSION A modest reduction of salt and replacement of SFA with PUFA in food products can significantly reduce the burden of CVD in the adult Finnish population. This impact may be even larger in the near future due to the ageing of Finnish population.

Abstract
OBJECTIVE To assess the cost-effectiveness of aripiprazole versus olanzapine in the treatment of patients with schizophrenia or bipolar disorder in Sweden with focus on the metabolic impact of the treatments. METHOD A Markov health-state transition model was developed. The risks of developing metabolic syndrome after one year of treatment with aripiprazole or olanzapine were derived from a pooled analysis of three randomised clinical trials. The subsequent risks of developing diabetes or coronary heart disease were based on previously published risk models. A societal perspective was applied, adopting a lifetime horizon. Univariate and probabilistic sensitivity analyses were conducted. RESULTS Treatment with aripiprazole dominates over olanzapine in both schizophrenia and bipolar disorder. In schizophrenia, quality-adjusted life-years (QALYs) gained were 0.08 and cost savings Swedish kronor (SEK) 30,570 (USD 4000); in bipolar disorder, QALYs gained were 0.09 and cost savings SEK 28,450 (USD 3720). In probabilistic sensitivity analyses, aripiprazole resulted in a dominant outcome in 84% of cases in schizophrenia and in 77% of cases in bipolar syndrome. CONCLUSION The significantly lower risk of developing metabolic syndrome observed with aripiprazole compared with olanzapine is associated with less risk of diabetes and cardiovascular morbidity and mortality that translates into lower overall treatment cost and improved quality of life over time.

Abstract
BACKGROUND The EQ-5D has been extensively used to assess patient utility in trials of new treatments within the cardiovascular field. The aims of this study were to review evidence of the validity and reliability of the EQ-5D, and to summarise utility scores based on the use of the EQ-5D in clinical trials and in studies of patients with cardiovascular disease. METHODS A structured literature search was conducted using keywords related to cardiovascular disease and EQ-5D. Original research studies of patients with cardiovascular disease that reported EQ-5D results and its measurement properties were included. RESULTS Of 147 identified papers, 66 met the selection criteria, with 10 studies reporting evidence on validity or reliability and 60 reporting EQ-5D responses (VAS or self-classification). Mean EQ-5D index-based scores ranged from 0.24 (SD 0.39) to 0.90 (SD 0.16), while VAS scores ranged from 37 (SD 21) to 89 (no SD reported). Stratification of EQ-5D index scores by disease severity revealed that scores decreased from a mean of 0.78 (SD 0.18) to 0.51 (SD 0.21) for mild to severe disease in heart failure patients and from 0.80 (SD 0.05) to 0.45 (SD 0.22) for mild to severe disease in angina patients. CONCLUSIONS The published evidence generally supports the validity and reliability of the EQ-5D as an outcome measure within the cardiovascular area. This review provides utility estimates across a range of cardiovascular subgroups and treatments that may be useful for future modelling of utilities and QALYs in economic evaluations within the cardiovascular area.

Abstract
CONTEXT Geoffrey Rose's two principal approaches to public health intervention are (1) targeted strategies focusing on individuals at a personal increased risk of disease and (2) population-wide approaches focusing on the whole population. Beyond his discussion of the strengths and weaknesses of these approaches, there is no empiric work examining the conditions under which one of these approaches may be better than the other. METHODS This article uses mathematical simulations to model the benefits and costs of the two approaches, varying the cut points for treatment, effect magnitudes, and costs of the interventions. These techniques then were applied to the specific example of an intervention on blood pressure to reduce cardiovascular disease. FINDINGS In the general simulation (using an inverse logit risk curve), lower costs of intervention, treating people with risk factor values at or above where the slope on the risk curve is at its steepest (for targeted interventions), and interventions with larger effects on reducing the risk factor (for population-wide interventions) provided benefit/cost advantages. In the specific blood pressure intervention example, lower-cost population-wide interventions had better benefit/cost ratios, but some targeted treatments with lower cutoffs prevented more absolute cases of disease. CONCLUSIONS These simulations empirically evaluate some of Rose's original arguments. They can be replicated for particular interventions being considered and may be useful in helping public health decision makers assess potential intervention strategies.

Abstract
BACKGROUND ASCOT (Anglo-Scandinavian Cardiac Outcomes Trial) showed in hypertensive patients that blood pressure-lowering treatment with an amlodipine-based regimen reduces events compared with an atenolol-based regimen and that atorvastatin was more effective than placebo. OBJECTIVE To assess the cost effectiveness of four alternative treatment strategies in patients with hypertension and three or more cardiovascular risk factors in the UK (from the UK NHS perspective) or Sweden (from the societal perspective): amlodipine-based plus atorvastatin, atenolol-based plus atorvastatin, amlodipine-based alone and atenolol-based alone. METHODS Based on the trial data, a Markov model was constructed where the risk of myocardial infarction, revascularization procedures and stroke and the long-term costs, quality of life and mortality associated with these events were estimated. Transition probabilities and costs (euro, 2007 values) were based on the patient-level trial data. Outcomes were reported as life-years gained and QALYs. In the latter case, utility reduction from events was based on a substudy in ASCOT patients. Treatment was applied for the duration of the lipid-lowering arm of the trial (3 years) and patients were then followed to the end of their life. RESULTS Amlodipine-based therapy plus atorvastatin was the most expensive but also most effective treatment. Compared with amlodipine-based therapy alone, the cost to gain one QALY was euro 11,965 in the UK and euro 8,591 in Sweden. The incremental cost effectiveness of amlodipine-based therapy compared with atenolol-based therapy was euro 9,548 and euro 3,965 per QALY gained in the UK and Sweden, respectively. Atenolol-based therapy plus atorvastatin was eliminated through extended dominance. Applying the threshold values used by the National Institute for Health and Clinical Excellence (NICE) and the Swedish National Board of Health and Welfare, a combination of amlodipine-based therapy and atorvastatin appears to be cost effective in patients with hypertension and three or more additional risk factors.

Abstract
BACKGROUND Currently little data exist on the development of quality of life over time in patients suffering from stroke, in particular using instruments that can be adapted in economic studies. The purpose of the study was to assess the utility loss and indirect costs following a stroke in Sweden. DESIGN A cross-sectional mail survey. METHODS In collaboration with the National Stroke registry (RIKS-STROKE), a questionnaire consisting of the EuroQol-5D and questions regarding the present working status and the status prior to the stroke was mailed to patients below 76 years of age at six participating centres. The questionnaire was mailed to 393 patients in total, divided into groups with 3, 6, 9 or 12 months having passed since the stroke. The EuroQol-5D scores were converted to utility scores using the UK social tariff. Indirect costs were valued according to the average salary+employer contributions. RESULTS A total of 275 questionnaires (70%) were returned. Utility scores were similar over time: 0.65, 0.75, 0.63, and 0.67 at 3, 6, 9 and 12 months, respectively. Regression analyses revealed a tendency for lower utility scores among women, but no significant differences overall. Among patients in the working ages, a stroke caused 18.5 work weeks lost, corresponding to an indirect cost of 120,000 Swedish Kronor (SEK) (13,200euro, 95% confidence interval 82,541-160,050 SEK, 9080-17 605euro). CONCLUSIONS Stroke causes a significant reduction in utility and causes high indirect costs. A substantial improvement was not noted over time, which is important to consider in economic models.
