RESUMO
BACKGROUND: This systematic review aims to describe the relation between physical inactivity and healthcare costs, by taking into account healthcare costs of physical-inactivity-related diseases (common practice), including physical-activity-related injuries (new) and costs in life-years gained due to avoiding diseases (new), whenever available. Moreover, the association between physical inactivity and healthcare costs may both be negatively and positively impacted by increased physical activity. METHODS: A systematic review was conducted, including records reporting on physical (in)activity in relation to healthcare costs for a general population. Studies were required to report sufficient information to calculate the percentage of total healthcare costs potentially attributable to physical inactivity. RESULTS: Of the 264 records identified, 25 were included in this review. Included studies showed substantial variation in the assessment methods of physical activity and in type of costs included. Overall, studies showed that physical inactivity is related to higher healthcare costs. Only one study included costs of healthcare resources used in prolonged life when physical-inactivity-related diseases were averted, showing net higher healthcare costs. No study included healthcare costs for physical-activity-related injuries. CONCLUSIONS: Physical inactivity is associated with higher healthcare costs in the general population in the short-term. However, in the long-term aversion of diseases related with physical inactivity may increase longevity and, as a consequence, healthcare costs in life-years gained. Future studies should use a broad definition of costs, including costs in life-years gained and costs related to physical-activity-related injuries.

BACKGROUND: Traumatic brain injury (TBI) is the main cause of mortality and severe morbidity in cyclists admitted to Dutch emergency departments (EDs). Although the use of bicycle helmets is an effective way of preventing TBI, this is uncommon in the Netherlands. An option to increase its use is through a legal enforcement. However, little is known about the cost-effectiveness of such mandatory use of helmets in the Dutch context. The current study aimed to assess the cost-effectiveness of a law that enforces helmet use to reduce TBI and TBI-related mortality. METHODS: The cost-effectiveness was estimated through decision tree modelling. In this study, wearing bicycle helmets enforced by law was compared with the current situation of infrequent voluntary helmet use. The total Dutch cycling population, consisting of 13.5 million people, was included in the model. Model data and parameters were obtained from Statistics Netherlands, the National Road Traffic Database, Dutch Injury Surveillance System, and literature. Effects included were numbers of TBI, death, and disability-adjusted life years (DALY). Costs included were healthcare costs, costs of productivity losses, and helmet costs. Sensitivity analysis was performed to assess which parameter had the largest influence on the incremental cost-effectiveness ratio (ICER). RESULTS: The intervention would lead to an estimated reduction of 2942 cases of TBI and 46 deaths. Overall, the incremental costs per 1) death averted, 2) per TBI averted, and 3) per DALY averted were estimated at 1) 2,002,766, 2) 31,028 and 3) 28,465, respectively. Most favorable were the incremental costs per DALY in the 65+ age group: 17,775. CONCLUSIONS: The overall costs per DALY averted surpassed the Dutch willingness to pay threshold value of 20,000 for cost-effectiveness of preventive interventions. However, the cost per DALY averted for the elderly was below this threshold, indicating that in this age group largest effects can be reached. If the price of a helmet would reduce by 20%, which is non-hypothetical in a situation of large-scale purchases and use of these helmets, the introduction of this regulation would result in an intervention that is almost cost-effective in all age groups.

BACKGROUND: Implementation of food taxes or subsidies may promote healthier and a more sustainable diet in a society. This study estimates the effects of a tax (15% or 30%) on meat and a subsidy (10%) on fruit and vegetables (F&V) consumption in the Netherlands using a social cost-benefit analysis with a 30-year time horizon. METHODS: Calculations with the representative Dutch National Food Consumption Survey (2012-2014) served as the reference. Price elasticities were applied to calculate changes in consumption and consumer surplus. Future food consumption and health effects were estimated using the DYNAMO-HIA model and environmental impacts were estimated using Life Cycle Analysis. The time horizon of all calculations is 30 year. All effects were monetarized and discounted to 2018 euros. RESULTS: Over 30-years, a 15% or 30% meat tax or 10% F&V subsidy could result in reduced healthcare costs, increased quality of life, and higher productivity levels. Benefits to the environment of a meat tax are an estimated 3400 million or 6300 million in the 15% or 30% scenario respectively, whereas the increased F&V consumption could result in 100 million costs for the environment. While consumers benefit from a subsidy, a consumer surplus of 10,000 million, the tax scenarios demonstrate large experienced costs of respectively 21,000 and 41,000 million. Overall, a 15% or 30% price increase in meat could lead to a net benefit for society between 3100-7400 million or 4100-12,300 million over 30 years respectively. A 10% F&V subsidy could lead to a net benefit to society of 1800-3300 million. Sensitivity analyses did not change the main findings. CONCLUSIONS: The studied meat taxes and F&V subsidy showed net total welfare benefits for the Dutch society over a 30-year time horizon.

BACKGROUND: Both out-of-pocket costs and financial rewards can be used to influence health related behavior. However, it is unclear which of these two has a larger effect on health related behavior. The aim of this study was to explore the possible difference in effect size between out-of-pocket costs and financial rewards on the willingness of diabetes mellitus type 2 (DM2) patients to participate in a lifestyle program. METHODS: A discrete choice experiment (DCE) questionnaire was sent to 767 DM2 patients in a geographically defined area (De Leidsche Rijn, Utrecht) in The Netherlands and completed by 206 of them. The questionnaire comprised of 18 choice tasks of which 9 contained a financial reward for lifestyle program completion, while the other 9 included out-of-pocket costs for program participation. In a second version of the questionnaire, the order of out-of-pocket cost and financial reward choice tasks was counterbalanced to reduce bias with respect to the position (first or second) of the two types of choice tasks. Panel-mixed-multinomial-logit models were used for data analysis. RESULTS: Increasing out-of-pocket costs were associated with a decreasing willingness to participate in a lifestyle program and, contrary to our expectations, increasing financial rewards were also associated with a decreasing willingness to participate in a lifestyle program. In addition, this willingness to participate changed to the same extent for both increasing out-of-pocket costs and increasing financial rewards. CONCLUSIONS: As expected, increasing out-of-pocket costs may prevent people from deciding to participate in a lifestyle program. However, offering a financial reward to persuade people to participate in a lifestyle program, may result in decreasing willingness to participate in a lifestyle program as well.

BACKGROUND: Participation rates of lifestyle programs among type 2 diabetes mellitus (T2DM) patients are less than optimal around the globe. Whereas research shows notable delays in the development of the disease among lifestyle program participants. Very little is known about the relative importance of barriers for participation as well as the willingness of T2DM patients to pay for participation in such programs. The aim of this study was to identify the preferences of T2DM patients with regard to lifestyle programs and to calculate participants' willingness to pay (WTP) as well as to estimate the potential participation rates of lifestyle programs. METHODS: A Discrete Choice Experiment (DCE) questionnaire assessing five different lifestyle program attributes was distributed among 1250 Dutch adults aged 35-65 years with T2DM, 391 questionnaires (31%) were returned and included in the analysis. The relative importance of the program attributes (i.e., meal plan, physical activity (PA) schedule, consultation structure, expected program outcome and out-of-pocket costs) was determined using panel-mixed logit models. Based on the retrieved attribute estimates, patients' WTP and potential participation rates were determined. RESULTS: The out-of-pocket costs (ß = -0.75, P < .001), consultation structure (ß = -0.46, P < .001) and expected outcome (ß =0.72, P < .001) were the most important factors for respondents when deciding whether to participate in a lifestyle program. Respondents were willing to pay 128 per year for individual instead of group consultation and 97 per year for 10 kilograms anticipated weight loss. Potential participation rates for different lifestyle-program scenarios ranged between 48.5% and 62.4%. CONCLUSIONS: When deciding whether to participate in a lifestyle program, T2DM patients are mostly driven by low levels of out-of-pocket costs. Thereafter, they prefer individual consultation and high levels of anticipated outcomes with respect to weight loss.

BACKGROUND: In recent years the literature regarding the cost-effectiveness of disease prevention and health promotion has grown exponentially. Aim of this study is to investigate: (i) how many and what type of economic evaluations have been published in 2008, (ii) the diseases or health problems World Health Organization International Classification of Diseases 10 chapters the economic evaluations of preventive interventions focus on, in relation to the global burden of disease and (iii) the cost-effectiveness of these interventions. METHODS: Literature study of economic evaluations on preventive interventions in PubMed and Scopus. RESULTS: In 2008, 232 economic evaluations of preventive interventions have been published. Of these studies, 75% (n = 175) used costs per (Quality Adjusted) Life Year [(QA)LY] gained as outcome measure. Most economic evaluations focus on the prevention of infectious diseases (31.5%, n = 73) and cancers (21%, n = 49) Infectious diseases are responsible for the highest global burden of disease (19.8%), followed by mental and behavioural disorders (11.7%). Of the included economic evaluations, 80% remained below a threshold of 50 000 and 60% below 20 000 per (QA)LY. CONCLUSION: This study shows that many economic evaluations of preventive interventions use a generic outcome measure. This adds to the comparability of different studies on the cost-effectiveness of prevention. Although the focus of published economic evaluations in general corresponds well with those diseases that cause a large share of the world's burden of disease, mental and behavioural diseases and diseases of the respiratory system remain underrepresented. Finally, it appears that the vast majority of published economic evaluations of preventive measures show favourable cost-effectiveness levels.

Hand dermatitis is a prevalent disease with an episodic, chronic character. The use of medical resources is high and is often related to reduced (work) functioning. The burden is therefore high for patients and society. Management of hand dermatitis is often unsatisfactory, and for this reason prevention is important. The effectiveness of prevention programmes is, however, unknown. This study evaluates if comprehensive prevention programmes for hand dermatitis, that include worker education as an element, are effective on occurrence, adherence to preventive measures, clinical outcomes and costs compared to usual care or no intervention. The literature was systematically searched using PubMed and Embase, from the earliest to January 2010 for relevant citations. The methodological quality was assessed by two reviewers using the Cochrane criteria. The GRADE approach was used to determine the level of evidence. After reading the full text articles, 7 publications met our inclusion criteria. We found that there is moderate evidence for the effect of prevention programmes on lowering occurrence and improving adherence to preventive measures, and low evidence for the effect on improving clinical outcomes and self-reported outcomes. No studies reporting on costs were found. It can be concluded that there is moderate evidence for the effectiveness of prevention programmes of hand dermatitis versus usual care or no intervention. However, more high quality studies including cost-effectiveness are needed.

BACKGROUND: Alcohol abuse results in problems on various levels in society. In terms of health, alcohol abuse is not only an important risk factor for chronic disease, but it is also related to injuries. Social harms which can be related to drinking include interpersonal problems, work problems, violent and other crimes. The scope of societal costs related to alcohol abuse in principle should be the same for both economic evaluations and cost-of-illness studies. In general, economic evaluations report a small part of all societal costs. To determine the cost- effectiveness of an intervention it is necessary that all costs and benefits are included. The purpose of this study is to describe and quantify the difference in societal costs incorporated in economic evaluations and cost-of-illness studies on alcohol abuse. METHOD: To investigate the economic costs attributable to alcohol in cost-of-illness studies we used the results of a recent systematic review (June 2009). We performed a PubMed search to identify economic evaluations on alcohol interventions. Only economic evaluations in which two or more interventions were compared from a societal perspective were included. The proportion of health care costs and the proportion of societal costs were estimated in both type of studies. RESULTS: The proportion of healthcare costs in cost-of-illness studies was 17% and the proportion of societal costs 83%. In economic evaluations, the proportion of healthcare costs was 57%, and the proportion of societal costs was 43%. CONCLUSIONS: The costs included in economic evaluations performed from a societal perspective do not correspond with those included in cost-of-illness studies. Economic evaluations on alcohol abuse underreport true societal cost of alcohol abuse. When considering implementation of alcohol abuse interventions, policy makers should take into account that economic evaluations from the societal perspective might underestimate the total effects and costs of interventions.
RESUMO
BACKGROUND: The introduction of bundled payment for maternity care, aimed at improving the quality of maternity care, may affect pregnant women's choice in providers of maternity care. This paper describes a Dutch study which examined pregnant women's preferences when choosing a maternity care provider. The study focused on factors that enhance the quality of maternity care versus (restricted) provider choice. METHODS: A discrete choice experiment was conducted amongst 611 pregnant women living in the Netherlands using an online questionnaire. The data were analysed with Latent Class Analyses. The outcome measure consisted of stated preferences in the discrete choice experiment. Included factors were: information exchange by care providers through electronic medical records, information provided by midwife, information provided by friends, freedom to choose maternity care provider and travel distance. RESULTS: Four different preference structures were found. In two of those structures, respondents found aspects of the maternity care related to quality of care more important than being able to choose a provider (provider choice). In the two other preference structures, respondents found provider choice more important than aspects related to quality of maternity care. CONCLUSIONS: In a country with presumed high-quality maternity care like the Netherlands, about half of pregnant women prefer being able to choose their maternity care provider over organisational factors that might imply better quality of care. A comparable amount of women find quality-related aspects most important when choosing a maternity care provider and are willing to accept limitations in their choice of provider. These insights are relevant for policy makers in order to be able to design a bundled payment model which justify the preferences of all pregnant women.

It is widely acknowledged that in order to promote public health and prevent diseases, a wide range of scientific disciplines and sectors beyond the health sector need to be involved. Evidence-based interventions, beyond preventive health interventions targeting disease risk factors and interventions from other sectors, should be developed and implemented. Investing in these preventive health policies is challenging as budgets have to compete with other governmental expenditures. The current study aimed to identify, compare and rank cost-effective preventive interventions targeting metabolic, environmental, occupational and behavioral risk factors. To identify these interventions, a literature search was performed including original full economic evaluations of Western country interventions that had not yet been implemented in the Netherlands. Several workshops were held with experts from different disciplines. In total, 51 different interventions (including 13 cost saving interventions) were identified and ranked based on their incremental cost-effectiveness ratio (ICER) and potential averted disability-adjusted life years (DALYs), resulting in two rankings of the most cost-effective interventions and one ranking of the 13 cost saving interventions. This approach, resulting in an intersectoral ranking, can assist policy makers in implementing cost-effective preventive action that considers not only the health sector, but also other sectors.

In many integrated care programs, a comprehensive geriatric assessment (CGA) is conducted to identify older people's problems and care needs. Different ways for conducting a CGA are in place. However, it is still unclear which CGA instruments and procedures for conducting them are used in integrated care programs, and what distinguishes them from each other. Furthermore, it is yet unknown how and to what extent CGAs, as a component of integrated care programs, actually reflect the main principles of integrated care, being comprehensiveness, multidisciplinarity and person-centredness. Therefore, the objectives of this study were to: (a) describe and compare different CGA instruments and procedures conducted within integrated care programs for older people living at home, and (b) describe how the principles of integrated care were applied in these CGAs. A scoping review of the scientific literature on CGAs in the context of integrated care was conducted for the period 2006-2018. Data were extracted on main characteristics of the identified CGA instruments and procedures, and on how principles of integrated care were applied in these CGAs. Twenty-seven integrated care programs were included in this study, of which most were implemented in the Netherlands and the United States. Twenty-one different CGAs were identified, of which the EASYcare instrument, RAI-HC/RAI-CHA and GRACE tool were used in multiple programs. The majority of CGAs seemed to reflect comprehensiveness, multidisciplinarity and person-centredness, although the way and extent to which principles of integrated care were incorporated differed between the CGAs. This study highlights the high variability of CGA instruments and procedures used in integrated care programs. This overview of available CGAs and their characteristics may promote (inter-)national exchange of CGAs, which could enable researchers and professionals in choosing from the wide range of existing CGAs, thereby preventing them from unnecessarily reinventing the wheel.

INTRO: Toxoplasmosis has high disease burden in the Netherlands and in the rest of Europe. It can be acquired directly by ingestion of Toxoplasma gondii (T. gondii) oocysts shed by infected cats, or indirectly via consumption of undercooked meat from infected livestock. Cat vaccination has been proposed for reducing oocyst-acquired human infections but it remains unclear whether such an intervention can be effective. In this study we quantified the effects of using cat vaccination on reducing oocyst-originated T. gondii human infections. METHOD: By using a disease dynamics compartmental model for T. gondii infections in cats and mice we studied the effects of a hypothetical cat vaccine on the presence of T. gondii oocysts in the environment. A fitted dose response model was used to assess the effect of oocyst reduction on the expected human infections. RESULTS: For rats, mice and pigs, and possibly intermediate hosts in general, ingestion of one oocyst provides 30%-60% probability of T. gondii infection. Assuming a favourable ideal scenario where vaccination completely prevents oocyst shedding and predation rate is of one mouse per week per cat, eight cats can be left susceptible in order to achieve elimination and stop oocyst-originated transmission, independent of the total cat population. Considering populations of 1000, 100, 50 and 20 cats, cat vaccination coverage of 94%, 68%, 54% and 35%, respectively, would reduce expected oocyst-originated human cases by 50%. CONCLUSION: For attaining elimination of oocyst-originated human infections, only few cats may remain unvaccinated, regardless of the cat-population size, and only a few more cats may remain unvaccinated for reducing infections substantially. Such vaccination coverages can in practice be achieved only when small cat-populations are considered, but in larger cat-populations the large efficacy and vaccination coverage needed are unfeasible.
RESUMO
Several biases can occur when performing economic evaluations (EE) and it is important for researchers to minimize these biases, as they can significantly affect economic outcomes. This review aims, firstly, to identify biases that can occur in model-based EE and to illustrate their impact on economic outcomes and, secondly, to present a checklist for assessing the overall risk of bias in EE. Eleven biases that can occur in model-based studies were identified through a scoping review, scrutiny of systematic reviews, the authors' own experiences and discussions with experts. By combining these biases that can occur in model-based studies with biases that were identified for trial-based studies in a previous article, a 22-item checklist was developed for assessing bias in EE - the ECOBIAS checklist. This study and the ECOBIAS checklist aim to help researchers reduce biases in future EE, particularly in model-based EE. Nevertheless, further validation of the checklist is needed.

Dutch young people are generally healthy, and more than 80% of them feel healthy and happy. This percentage is high compared with other European countries. Infant mortality rates are low, and the prevalence of most health problems among children is less than 10%. However, children from risk groups more often engage in unhealthy behaviours or have psychosocial problems. Adolescents smoke and drink less than they did 10 years ago, but extreme alcohol use has increased. The number of overweight children has stabilised in the past few years, but remains at a high level. These trends are expected to follow the same line in the future. Attention to the increasing use of social media is important, and the increasing number of high-risk children will also require attention. Due to these changes, along with policy changes in the provision of healthcare services for young people, intensive communication and cooperation between general practitioners, healthcare physicians, and care workers responsible for young people is increasingly important.

Increasing healthcare costs force policy makers to make difficult choices in the insurance package. In order to make rational choices, there must be an understanding of the healthcare costs as well as the value of the health that the care provides. Health economists have in recent years carried out extensive research into the value that people attribute to health. Health is of great social value, and is difficult to express in concrete monetary terms. One extra life-year in good health ('quality-adjusted life year', QALY) seems to be valued on average at no less than 50,000 euros by people. Methodology needs to be developed in this area so that study results are more uniform and can be better compared. Physicians and policy makers will thus gain more insight into the value of health.

Objectives The aim of the present study was to estimate the cost-effectiveness of the polypill in the primary prevention of cardiovascular disease. Design A health economic modelling study. Setting Primary healthcare in the Netherlands. Participants Simulated individuals from the general Dutch population, aged 45-75 years. Interventions Opportunistic screening followed by prescription of the polypill to eligible individuals. Eligibility was defined as having a minimum 10-year risk of cardiovascular death as assessed with the Systematic Coronary Risk Evaluation function of alternatively 5%, 7.5% or 10%. Different versions of the polypill were considered, depending on composition: (1) the Indian polycap, with three different types of blood pressure-lowering drugs, a statin and aspirin; (2) as (1) but without aspirin and (3) as (2) but with a double statin dose. In addition, a scenario of (targeted) separate antihypertensive and/or statin medication was simulated. Primary outcome measures Cases of acute myocardial infarction or stroke prevented, quality-adjusted life years (QALYs) gained and the costs per QALY gained. All interventions were compared with usual care. Results All scenarios were cost-effective with an incremental cost-effectiveness ratio between 7900 and 12â300 per QALY compared with usual care. Most health gains were achieved with the polypill without aspirin and containing a double dose of statins. With a 10-year risk of 7.5% as the threshold, this pill would prevent approximately 3.5% of all cardiovascular events. Conclusions Opportunistic screening based on global cardiovascular risk assessment followed by polypill prescription to those with increased risk offers a cost-effective strategy. Most health gain is achieved by the polypill without aspirin and a double statin dose.
RESUMO
BACKGROUND: Several studies suggest that lifestyle interventions can be effective for people with, or at risk for, diabetes. The participation in lifestyle interventions is generally low. Financial incentives may encourage participation in lifestyle intervention programs. OBJECTIVE: The main aim of this exploratory analysis is to study empirically potential effects of financial incentives on diabetes patients' willingness to participate in lifestyle interventions. One financial incentive is negative ("copayment") and the other incentive is positive ("bonus"). The key part of this research is to contrast both incentives. The second aim is to investigate the factors that influence participation in a lifestyle intervention program. METHODS: Conjoint analysis techniques were used to empirically identify factors that influence willingness to participate in a lifestyle intervention. For this purpose diabetic patients received a questionnaire with descriptions of various forms of hypothetical lifestyle interventions. They were asked if they would be willing to participate in these hypothetical programs. RESULTS: In total, 174 observations were rated by 46 respondents. Analysis showed that money was an important factor independently associated with respondents' willingness to participate. Receiving a bonus seemed to be associated with a higher willingness to participate, but having to pay was negatively associated with participation in the lifestyle intervention. CONCLUSION: Conjoint analysis results suggest that financial considerations may influence willingness to participate in lifestyle intervention programs. Financial disincentives in the form of copayments might discourage participation. Although the positive impact of bonuses is smaller than the negative impact of copayments, bonuses could still be used to encourage willingness to participate.
RESUMO
OBJECTIVE: To review the current literature concerning the effectivity and cost-effectiveness of screening for abdominal aortic aneurysm (AAA). DESIGN: Systematic review. METHOD: A review of literature of evaluations of effectivity via meta-analyses and economic evaluations. RESULTS: The short-term meta-analyses showed that screening for AAA leads to a significant reduction of AAA-related mortality. The average absolute risk reduction (ARR) was 0.12%. The long-term meta-analysis also showed a significant reduction of overall mortality. The ARR was in this case almost 1%. The five economic evaluations all resulted in cost-effectiveness ratios below euro 20,000 per quality-adjusted life year (QALY), a used threshold level in the Netherlands. CONCLUSION: Based on the available literature, screening for AAA has appeared to be both effective and cost-effective. However, the economic evaluations did not always take into account the peri- and post-operative mortality and morbidity. Economic evaluations are only useful if all possible outcomes are included in the model. Therefore a good model analysis should be made for the Dutch situation, after which a decision may be taken on a possible pilot study and the optimal design thereof.
