The direct and indirect costs of sleep disorders are high. The total financial costs (independent of the cost of suffering) of dollar 4524 million represents 0.8% of Australian gross domestic product. The cost of suffering of dollar 2970 million is 1.4% of the total burden of disease in Australia.

This study aims to provide a rigorous estimate of the worldwide costs of visual impairment (VI), and the associated health burden. The study used a prevalence-based model. Prevalence rates for mild VI (visual acuity (VA) worse than 6/12 but not worse than 6/18), moderate VI (VA worse than 6/18 but not worse than 6/60) and blindness (VA worse than 6/60) were applied to population forecasts for each World Health Organisation (WHO) subregion. The limited available country cost data were extrapolated between subregions using economic and population health indicators. Age and gender subgroup population numbers were derived from United Nations' data. Costs and the health burden of VI were estimated for each world subregion using published disease prevalence rates, health care expenditures and other economic data. The study includes direct health care costs, indirect costs and the health burden of VI. The total cost of VI globally was estimated at $3 trillion in 2010, of which $2.3 trillion was direct health costs. This burden is projected to increase by approximately 20% by 2020. VI is associated with a considerable disease burden. Unless steps are taken to reduce prevalence through prevention and treatment, this burden will increase alongside global population growth.

The financial and nonfinancial costs associated with inadequate sleep are substantial. The estimated total financial cost of $17.88 billion represents 1.55 per cent of Australian gross domestic product. The estimated nonfinancial cost of $27.33 billion represents 4.6 per cent of the total Australian burden of disease for the year. These costs warrant substantial investment in preventive health measures to address the issue through education and regulation.

Objective To estimate one‐year costs of eating disorders in the United States (U.S.) from a societal perspective, including the costs to the U.S. health system, individual and family productivity costs, lost wellbeing, and other societal economic costs, by setting and payer. Findings will inform needed policy action to mitigate the impact of eating disorders in the U.S. Method Costs of eating disorders were estimated using a bottom‐up cost‐of‐illness methodology, based on the estimated one‐year prevalence of eating disorders. Intangible costs of reduced wellbeing were also estimated using disability‐adjusted life years. Results Total economic costs associated with eating disorders were estimated to be $64.7 billion (95% CI: $63.5–$66.0 billion) in fiscal year 2018–2019, equivalent to $11,808 per affected person (95% CI: $11,754–$11,863 per affected person). Otherwise Specified Feeding or Eating Disorder accounted for 35% of total economic costs, followed by Binge Eating Disorder (30%), Bulimia Nervosa (18%) and Anorexia Nervosa (17%). The substantial reduction in wellbeing associated with eating disorders was further valued at $326.5 billion (95% CI: $316.8–$336.2 billion). Discussion The impact of eating disorders in the U.S. is substantial when considering both economic costs and reduced wellbeing (nearly $400 billion in fiscal year 2018–2019). Study findings underscore the urgency of identifying effective policy actions to reduce the impact of eating disorders, such as through primary prevention and screening to identify people with emerging or early eating disorders in primary care, schools, and workplaces and ensuring access to early evidence‐based treatment.

BackgroundTo quantify the economic impact of sight loss and blindness in the United Kingdom (UK) population, including direct and indirect costs, and its burden on health.MethodsPrevalence data on sight loss and blindness by condition, Census demographic data, data on indirect costs, and healthcare cost databases were used. Blindness was defined as best corrected visual acuity (BCVA) of < 6/60, and sight loss as BCVA < 6/12 to 6/60, in the better-seeing eye.ResultsSight loss and blindness from age-related macular degeneration (AMD), cataract, diabetic retinopathy, glaucoma and under-corrected refractive error are estimated to affect 1.93 (1.58 to 2.31) million people in the UK. Direct health care system costs were £3.0 billion, with inpatient and day care costs comprising £735 million (24.6%) and outpatient costs comprising £771 million (25.8%). Indirect costs amounted to £5.65 (5.12 to 6.22) billion. The value of the loss of healthy life associated with sight loss and blindness was estimated to be £19.5 (15.9 to 23.3) billion or £7.2 (5.9 to 8.6) billion, depending on the set of disability weights used. For comparison with other published results using 2004 disability weights and the 2008 estimates, the total economic cost of sight loss and blindness was estimated to be £28.1 (24.0 to 32.5) billion in 2013. Using 2010 disability weights, the estimated economic cost of sight loss and blindness was estimated to be £15.8 (13.5 to 18.3) billion in 2013.ConclusionsThe large prevalence of sight loss and blindness in the UK population imposes significant costs on public funds, private expenditure, and health. Prevalence estimates relied on dated epidemiological studies and may not capture recent advances in treatment, highlighting the need for population-based studies that track the prevalence of sight-impairing eye conditions and treatment effects over time.Electronic supplementary materialThe online version of this article (10.1186/s12913-018-2836-0) contains supplementary material, which is available to authorized users.

BackgroundHeart conditions impose physical, social, financial and health-related quality of life limitations on individuals in Brazil.ObjectivesThis study assessed the economic burden of four main heart conditions in Brazil: hypertension, heart failure, myocardial infarction, and atrial fibrillation. In addition, the cost-effectiveness of telemedicine and structured telephone support for the management of heart failure was assessed.MethodsA standard cost of illness framework was used to assess the costs associated with the four conditions in 2015. The analysis assessed the prevalence of the four conditions and, in the case of myocardial infarction, also its incidence. It further assessed the conditions’ associated expenditures on healthcare treatment, productivity losses from reduced employment, costs of providing formal and informal care, and lost wellbeing. The analysis was informed by a targeted literature review, data scan and modelling. All inputs and methods were validated by consulting 15 clinicians and other stakeholders in Brazil. The cost-effectiveness analysis was based on a meta-analysis and economic evaluation of post-discharge programs in patients with heart failure, assessed from the perspective of the Brazilian Unified Healthcare System (Sistema Unico de Saude).ResultsMyocardial infarction imposes the greatest financial cost (22.4 billion reais/6.9 billion USD), followed by heart failure (22.1 billion reais/6.8 billion USD), hypertension (8 billion reais/2.5 billion USD) and, finally, atrial fibrillation (3.9 billion reais/1.2 billion USD). Telemedicine and structured telephone support are cost-effective interventions for achieving improvements in the management of heart failure.ConclusionsHeart conditions impose substantial loss of wellbeing and financial costs in Brazil and should be a public health priority.

ObjectivesTo estimate the economic impact of delirium in the Australian population in 2016–2017, including financial costs, and its burden on health.Design, setting and participantsA cost of illness study was conducted for the Australian population in the 2016–2017 financial year. The prevalence of delirium in 2016–2017 was calculated to inform cost estimations. The costs estimated in this study also include dementia attributable to delirium.Main outcome measuresThe total and per capita costs were analysed for three categories: health systems costs, other financial costs including productivity losses and informal care and cost associated with loss of well-being (burden of disease). Costs were expressed in 2016–2017 pound sterling (£) and Australian dollars ($A).ResultsThere were an estimated 132 595 occurrences of delirium in 2016–2017, and more than 900 deaths were attributed to delirium in 2016–2017. Delirium causes an estimated 10.6% of dementia in Australia. The total costs of delirium in Australia were estimated to be £4.3 billion ($A8.8 billion) in 2016–2017, ranging between £2.6 billion ($A5.3 billion) and £5.9 billion ($A12.1 billion). The total estimated costs comprised financial costs of £1.7 billion and the value of healthy life lost of £2.5 billion. Dementia attributable to delirium accounted for £2.2 billion of the total cost of delirium.ConclusionsThese findings highlight the substantial burden that delirium imposes on Australian society—both in terms of financial costs associated with health system expenditure and the increased need for residential aged care due to the functional and cognitive decline associated with delirium and dementia. To reduce the substantial well-being costs of delirium, further research should seek to better understand the potential pathways from an episode of delirium to subsequent mortality and reduced cognitive functioning outcomes.
