The use of hepatitis a vaccination in Italy: an economic evaluation.

We report on the conduct and results of an economic model of two different strategies of vaccination against hepatitis A in Italy. In strategy 1 (universal vaccination), all newborns are vaccinated simultaneously with MMR at 15 months and all 12 year olds are vaccinated with combined hepatitis A and B vaccine. In strategy 2 (contacts' vaccination) only subjects with a close social and spatial relationship with the sick are vaccinated. In strategy 1 costs per avoided case and net costs per avoided case values are always very high. Net costs become very low when newborns and 12 year olds are vaccinated, and become negative (indicating a potential gain) when 12 year olds are vaccinated. From an economic viewpoint, universal vaccination appears recommendable only in epidemic conditions. For strategy 2 our model shows that cost for avoidable case are very low and net costs for avoided case are always negative, showing the potential presence of an absolute benefit. We conclude that in Italy mass vaccination appears economically worthwhile only during epidemics but vaccination of contacts is an economically worthwhile routine measure.

Morbidity and Irish Catholic descent in Britain. Relating health disadvantage to socio-economic position.

In common with some other ethnic and religious minorities whose forebears migrated from their country of origin, Irish Catholics in Britain are less well off than the host population in terms of socio-economic position and health. Results are presented from a Scottish study, where Catholic religion of origin mainly indicates Irish ancestry, and it is estimated that about one-third of the population is of significant Irish descent. In this study, excess of physical and mental health problems and disability have previously been reported for those of Catholic background, particularly in the eldest cohort (aged 56 in 1988), and have not been fully explained by health-related behaviour. In this paper, we examine a number of key health measures, namely self-assessed health, number of symptoms in the month prior to interview, sadness or depression, disability and lung function, and various indicators of socio-economic position (head of household social class, main source of income, car ownership, housing tenure and school-leaving age), which all show Catholic disadvantage. Using longitudinal results from the 723 respondents who completed interviews both at sweeps one (1988) and three (1995), it is estimated that about half of the morbidity excess amongst middle-aged Catholics in Glasgow can be explained by socio-economic disadvantage. The health and socio-economic position of white minorities and disadvantaged religious minorities like Catholics in Scotland should be monitored by a co-ordinated information strategy.

The role of cultural and economic determinants in mortality decline in the Netherlands, 1875/1879-1920/1924: a regional analysis.

The objective of this study was to determine the relative importance of cultural and economic factors in mortality decline in the Netherlands in the periods 1875/1879-1895/1899 and 1895/1899-1920/1924. Mortality data by region, age, sex and cause of death as well as population data were derived from Statistics Netherlands for the years 1875/1879, 1885/1889, 1895/1899, 1910/1914, 1920/1924. Regional mortality declines were estimated on the basis of Poisson regression models. In a multivariate analysis the estimated declines were associated with economic (wealth tax) and cultural variables (% Roman Catholics and secularisation) corrected for confounders (soiltype, urbanisation). In the period from 1875/1879-1895/1899, %Roman Catholics was significantly associated with all-cause mortality decline and with mortality decline from diseases other than infectious diseases. Mortality declined less rapidly in areas with a high percentage of Roman Catholics. Secularisation was significantly associated with infectious-disease mortality decline. In areas with a high percentage population without a religious affiliation, mortality declined more rapidly. In the period from 1895/1899 to 1920/1924, wealth tax was significantly associated with all-cause and infectious-disease mortality decline. Mortality declined more rapidly in wealthy areas. Intermediary factors in the relationship between cultural factors and mortality decline were fertility decline, but more importantly, the number of medical doctors per 100,000 inhabitants. No intermediary factors were found for the association between the economic variable and mortality decline. Cultural and economic factors both played an important role in mortality decline in The Netherlands, albeit in different periods of time. The analysis of intermediary factors suggests that the acceptance of new ideas on hygiene and disease processes was an important factor in the association between culture and mortality decline in the late 19th century.

From home to hospital and back again: economic restructuring, end of life, and the gendered problems of place-switching health services.

Economic restructuring in the health services industry in the USA exemplifies general patterns of economic change propelled by neoliberalism, especially industry privatization, diminished social services, and dependence on "flexible" labor and management regimes. Combined with the widespread entry of women into the labor force, an aging population, and minimal assistance for high quality long-term care at the end of life, these economic and social conditions raise a set of difficult policy questions for health services planning. Set in these broad contexts, this paper situates access to and experience of health services in the home, the hospital, and nursing facility, to demonstrate how economic changes have relocated and redefined health services in ways that distinctively impact how people experience the places where they receive care. This place switching of health services externalizes costs of subacute and "daily life care" (the so-called custodial care) to the sphere of the individual, their family, and communities. The theoretical analysis uses current geographical and philosophical approaches to place and space, and considers the tensions between institutionally managed health care space, and the patient's experience of receiving health services in place. The place/space dilemma of health services provision is examined through several interrelated subjects: long-term care at the end of life, gendered characteristics of care giving, the limitations of Medicare and Medicaid, historical changes in hospital length of stay, the restructuring of nursing practices, and the "no-care zone". The analysis is based on examples of stroke and incontinence care to demonstrate the importance of considering place and space issues in health care planning.

Measuring the magnitude of socio-economic inequalities in health: an overview of available measures illustrated with two examples from Europe.

In this paper we review the available summary measures for the magnitude of socio-economic inequalities in health. Measures which have been used differ in a number of important respects, including (1) the measurement of "relative" or "absolute" differences; (2) the measurement of an "effect" of lower socio-economic status, or of the "total impact" of socio-economic inequalities in health upon the health status of the population; (3) simple versus sophisticated measurement techniques. Based on this analysis of summary measures which have previously been applied, eight different classes of summary measures can be distinguished. Because measures of "total impact" can be further subdivided on the basis of their underlying assumptions, we finally arrive at 12 types of summary measure. Each of these has its merits, and choice of a particular type of summary measure will depend partly on technical considerations, partly on one's perspective on socio-economic inequalities in health. In practice, it will often be useful to compare the results of several summary measures. These principles are illustrated with two examples: one on trends in the magnitude of inequalities in mortality by occupational class in Finland, and one on trends in the magnitude of inequalities in self-reported morbidity by level of education in the Netherlands.

Economic evaluation in support of national health policy: the case of The Netherlands.

This article focuses on economic evaluation as an instrument to support national health policy in the Netherlands. National health policy concerns decision-making on which technologies may enter the health care market, which health care services are included in the package of health care benefits and under what conditions, and what the geographical distribution of medical services and facilities should be. Regarding the latter two issues in particular, the actual and potential role of economic evaluation in health policy is discussed. From the Dutch experience we can learn that a close cooperation between researchers and policy-makers helps to enlarge the impact of economic appraisal on policy-making and that incorporation of the right (financial) incentives is vital to the use of economic appraisal in health care decision-making.

Some politico-economic aspects of organ shortage in transplantation medicine.

Transplantation of solid organs has become a widely performed and accepted procedure. This type of high-performance medicine has led to vigorous debates on ethical and economic issues and most of this discussion can be seen as an example of the different opinions about highly individualised and technologised approaches in health care. The paper focuses on the rising gap in the demand for suitable organs for transplantation and the levelling off, or even fall, in the supply of these organs. Despite the rather demanding requirements for organ donation, there appear to be a sufficient number of deaths under suitable circumstances to satisfy the annual demand of transplantable organs--if the collection rates are adequate. It has been shown that there are great differences in the rate of organ procurement efficiency within different regions. The question then is how to set appropriate incentives to obtain organs in sufficient quantities from eligible donors to meet the demand. This paper discusses the different medical and societal approaches as well as the economic proposals to overcome the organ shortage. The theory of Public Choice is used to develop a specific policy that can be applied to organ procurement efforts. This is a different approach, whereby political and economic considerations of ethical dilemmas focus on setting appropriate and widely accepted frameworks and rules, in which individuals may then decide about their behaviour. In an appendix, the economic consequences of transplantation medicine are discussed if more organs were to be made available and the impacts of relaxing the simplifying assumptions on effectiveness of organ replacement therapy and on the allocation system are considered. Ultimately, artificial organs or genetically transformed animal organs may be used but it is highly likely that a vigorous debate on the ethics and especially financial implications of these interventions will take place beforehand.

Socio-economic differences in health risk behavior in adolescence: do they exist?

Socio-economic differences in risk behaviors in adolescence can be seen as a prelude to the re-emergence of socio economic health differences in adulthood. We studied whether or not socio-economic differences in health risk behaviors are present in male and female adolescents in The Netherlands. The relation between socio-economic status (SES) and health risk behaviors was examined, by testing both the main and interaction effects of SES and gender on separate health risk behaviors on one hand, and on the behaviors cumulatively on the other. The data were derived from 1984 adolescents in the four northern provinces of The Netherlands. SES was measured by means of the educational level and the occupational status of both parents. Four health risk behaviors were included in this study: smoking, alcohol consumption, soft drug use, and (no) physical exercise. We found that the relationships between SES and health risk behaviors are not as linear as is often found in adulthood. Our findings can be characterised overall by an absence of relationship between SES and health risk behaviors. The only exception applies to sport, which is linearly related to SES. Adolescents in the lower SES groups engage in sport less than adolescents in the higher SES groups. There was an irregular relationship between the father's occupational status and the adolescents' smoking and drinking. Adolescents in the highest, lowest and middle of the six SES groups have the highest rates of health risk behaviors. All observed relationships are similar for both male and female adolescents. A relationship between gender and the separate health risk behaviors was found only for alcohol consumption and drug use. For both male adolescents showed higher rates of risk behavior. Males also scored higher on the cumulative health risk behaviors than their female counterparts. The findings of this study do not support the hypothesis of latent differences in adolescence.

Maternal mortality, women's status, and economic dependency in less developed countries: a cross-national analysis.

While much has been written about the medical, economic, and social causes of cross-national differences in some mortality related phenomena such as in life expectancy and infant mortality, much less attention has been given to maternal mortality, the focus of the present study. In the studies of maternal mortality that have been done, there has been very little effort to assess the potential relevance of the gender stratification and dependency theory perspectives. Using lagged cross-sectional and path analysis with a sample of 79 less developed countries, this article focuses on the impact of predictors linked to three theoretical perspectives - modernization, economic dependency, and gender stratification. We find that women's status, as measured by indicators such as level of education relative to men, age at first marriage, and reproductive autonomy, is a strong predictor of maternal mortality. We find that economic dependency, especially multinational corporate investment, has a detrimental effect on maternal mortality that is mediated by its harmful impacts on economic growth and the status of women. We also find support for developmental theory, a variant of modernization theory.

Caries-associated micro-organisms in infants from different socio-economic backgrounds in Scotland.

OBJECTIVES: The aims of this study were: (1) to compare the frequency of isolation of mutans streptococci, (Streptococcus mutans, Steptococcus sobrinus), lactobacilli and yeasts (caries-associated micro-organisms) in the saliva of 1-year-old infants with and without dental caries; and (2) to determine if socio-economic background influenced the frequency isolation of bacteria and caries status. METHODS: 1393 1-year-old consented infants, who comprised 70. 3% of children born in Dundee during a 1year period, had saliva samples taken (tongue-loop method) for microbiological culture and were examined for dental caries (d(1)-threshold: enamel and dentine diagnostic threshold). Thirty-nine infants were diagnosed with caries and the frequencies of isolation of caries-associated micro-organisms (and absolute microbial counts) were compared with infants who were caries-free. In addition, associations were sought between the infants' socio-economic background, the frequency of isolation of caries-associated micro-organisms and caries status. RESULTS: Streptococcus mutans, lactobacilli and yeasts were isolated more frequently from those infants with caries compared to those who were caries-free (S. mutans: 29.7 vs 9.8%, P=0.0008; lactobacilli: 15.4 vs 4.3%, P=0.0073; yeasts: 23.7 vs 10.4%, P=0.0016-Fisher's exact test). There were no significant differences between the isolation frequencies of S. sobrinus (2.7 vs 1.3%, P=0.39) from those with and without caries. Significantly, more infants living in areas of high deprivation had caries compared to those from more affluent areas (DEPCAT 6 and 7 vs 1-5: 3.6 vs 1.9%, P=0.049), but, apart from yeasts, socio-economic background was not significantly associated with the isolation frequencies of any of the caries-associated micro-organisms. CONCLUSIONS: In infants as young as 1year of age, salivary S. mutans, lactobacilli and yeasts but not S. sobrinus were isolated significantly more frequently from those with caries compared to those who were caries-free. Apart from yeasts, socio-economic background did not influence the frequency of isolation of caries-associated micro-organisms. However, infants living in areas of highest deprivation had significantly higher frequencies of caries compared to those from more affluent areas.

Economic growth, biodiversity loss and conservation effort.

This paper investigates the relationship between economic growth, biodiversity loss and efforts to conserve biodiversity using a combination of panel and cross section data. If economic growth is a cause of biodiversity loss through habitat transformation and other means, then we would expect an inverse relationship. But if higher levels of income are associated with increasing real demand for biodiversity conservation, then investment to protect remaining diversity should grow and the rate of biodiversity loss should slow with growth. Initially, economic growth and biodiversity loss are examined within the framework of the environmental Kuznets hypothesis. Biodiversity is represented by predicted species richness, generated for tropical terrestrial biodiversity using a species-area relationship. The environmental Kuznets hypothesis is investigated with reference to comparison of fixed and random effects models to allow the relationship to vary for each country. It is concluded that an environmental Kuznets curve between income and rates of loss of habitat and species does not exist in this case. The role of conservation effort in addressing environmental problems is examined through state protection of land and the regulation of trade in endangered species, two important means of biodiversity conservation. This analysis shows that the extent of government environmental policy increases with economic development. We argue that, although the data are problematic, the implications of these models is that conservation effort can only ever result in a partial deceleration of biodiversity decline partly because protected areas serve multiple functions and are not necessarily designated to protect biodiversity. Nevertheless institutional and policy response components of the income biodiversity relationship are important but are not well captured through cross-country regression analysis.

The valuation of the International Prostate Symptom Score (IPSS) for use in economic evaluations.

OBJECTIVE: Lower Urinary Tract Symptoms (LUTS) suggestive of Benign Prostatic Obstruction (BPO) cause a reduction in quality of life, but the magnitude of that reduction cannot be estimated empirically. This is because survey instruments currently available merely sum the symptoms found, but do not value their impact on quality of life. It is therefore difficult to determine whether the effects of treatments for LUTS suggestive of BPO justify the costs. This complicates economic evaluations. METHODS: We valued the impact on quality of life of patients with LUTS suggestive of BPO, by valuing health states defined by the International Prostate Symptom Score (IPSS) using the time trade-off (TTO). TTO values ranged from 1.0 for perfect health to 0.0 for the value of death, and can be used to calculate Quality-Adjusted Life Years (QALYs), the preferred outcome measure in health economics. RESULTS: We reduced the number of health states defined by the IPSS using factor analysis. The resulting nine health states were valued by a representative sample of the general public (N=170) using TTO. The worst IPSS health state was valued at 0.87. CONCLUSION: The values for health states defined by the IPSS revealed that LUTS suggestive of BPO has a mild impact on quality of life. The valuation of the IPSS facilitates economic evaluations of treatments for LUTS suggestive of BPO, because QALYs (the preferred outcome measure in health economics) can be determined empirically.

Waste-to-energy plant for paper industry sludges disposal: technical-economic study.

In this work, a detailed technical-economic analysis of a fluidized bed based waste-to-energy system for disposal of paper manufacturing sludges has been carried out. Specific reference is made to a case study represented by the largest plant in Italy producing recycled paper, with a daily sludge output of about 52t. The adopted plant has been sized for a nominal capacity of 140t per day also allowing the progressive elimination of sludges accumulated in a previously utilized landfill, giving a nominal electrical power output of 3.5MW. The main plant sections have been described and the adopted technical solutions have been outlined. A detailed process and equipment characterization has been carried out leading to a thorough evaluation of capital investment, operating costs and revenues. A differential analysis has been performed with respect to the alternative solution represented by the disposal of untreated sludges in an external landfill in order to highlight the savings obtainable. The economic profitability of the investment has been evaluated regarding several performance indices. The economic evaluation has been completed by a sensitivity and risk analysis in order to assess the effects of uncertainties in the economically significant parameters. Adopting most probable values, the savings obtained with the considered waste-to-energy system are evaluated in the 15--20 million Euro range during the estimated plant life of 15 years with a foreseen pay back time of 4 years. Moreover, many environmental benefits result such as the remediation of existing landfill, the avoidance of new landfills opening and very low air pollutants emissions.

Economics of gastrointestinal parasitism of cattle.

Understandably, cattle are raised for profit, as beef and/or dairy. Anything that negates that equation results in a loss to the producer and to the livestock economy. Thus, parasites negatively affect the economy of the industry. Worldwide, gastrointestinal nematode parasites, especially Ostertagia ostertagi, and those of the respiratory tract (Dictyocaulus viviparus) have a potentially major impact on herd health. In the past 10-15 years, anthelmintic (AH) drug development and the strategic use of AH have positively balanced the economic equation, so that overall, parasitism in cattle is often observed or determined to be subclinical or economical. Other control measures, such as better pasture management, are also being developed to enhance herd health and the cattle economy. The determination of the economic impact of parasitism has thus become less apparent, to the extent that measures, such as performance parameters, must be used to measure differences between treated and untreated animals or herds. These include weight gain, reproduction, lactation and forage use. To determine the effectiveness of control measures, field trials are designed to measure these parameters by the demonstration of improved performance. Because these trials are conducted in a competitive mode, results are often debated by competitors and by the scientific community because of study design. Variables must then be taken into consideration in the interpretation of results. It is now well known that, with the generation of new AH and appropriately-timed administration, parasitism of well-managed herds has been reduced to subclinical levels. Thus, we are now in the process of fine-tuning the positive effect of these control measures for enhanced production. Understandably, beef and dairy producers have 'production of high quality commodities' at a cost-effective level as a common goal. Successful cattlemen calculate expenditures and income by line item including veterinary expenses and cost and labor in administration of AH. Return is based on performance. Again, nematode parasites can disturb the equation enough to make production less profitable or even unprofitable. Most USA beef cattle producers believe that worm parasites do have an effect on cattle health and production so that 77% use AH and the market impact is that AH have become integrated into cattle herd health programs. However, to be most cost-effective, programs must be strategic but flexible with scheduling tailored for the region and the cattle operation. Other technologies should eventually provide rapid identification of worm populations by species and numbers and recognition of individual animal response to parasites and inheritance of that trait by their progeny. Computerized programs for analysis of seasonality of the epidemiology of gastrointestinal parasites and of herd performance could predict appropriate timing and cost benefit for control measures. Modes of AH administration are being developed which are more reliable and convenient in terms of delivery and labor. Control measures must also include better pasture management with less impact on the environment and to justify investment in land. In addition, successful producers are better educated, more cost-conscious, consumer-oriented, sensitive to the environment and attuned to the economics of parasitism.

Improving the assessment of the economic impact of parasitic diseases and of their control in production animals.

This paper reviews the ways in which the economic impact of parasitic diseases of production animals have been evaluated. It then discusses the shortfalls of such studies, as well as the opportunities for improving the quality of economic impact assessments and their value to decision makers in the future. The paper first identifies the impacts that are specific to parasitic diseases. It then goes on to review the abundant literature on estimating the total costs of diseases. The authors argue that this approach severely limits the opportunity for economic assessments to aid decisions in disease control and research. The paper then reviews the literature on studies of avoidable costs, before discussing ways in which economic impact assessments can be enhanced. These issues include greater emphasis on incorporating the lost productivity potential caused by parasitic diseases, greater emphasis on valuing actual rather than intended control measures, and greater emphasis on quantifying the productivity effects at the societal level, particularly in the developing world.

Clinical economics of head and neck malignancies.

With the continued increase in medical expenditures and the growing awareness that resources are not limitless, there is increasing pressure to curb health care costs and to establish priorities. As potential solutions are proposed and implemented, there is understandable concern that policy choices may adversely affect both the access to and the quality of care. Economic analyses are one tool used to optimize resource allocation decisions. The primary goal of these analyses is to maximize value and efficiency, not necessarily to decrease spending. The current focus on cost cutting is often associated with a more truncated, nonsocietal perspective (e.g., that of the payer or provider). To be most useful, these analyses must be methodologically rigorous. Standard guidelines, such as those established by Eisenberg, are helpful. As shown in the reports applicable to head and neck malignancies that have been discussed here, many articles published in the clinical literature must be interpreted cautiously, because fundamental methodological concerns (e.g., using costs rather than charges, discounting to a common base year) were frequently not addressed. Economic investigations are one aspect of the broader fields of outcomes and health services research. It is easy to underestimate how greatly economic studies depend on the availability of high quality noneconomic data. In that context, current initiatives in evidence-based medicine (EBM), using the best available evidence (considering for example, the type of trial, the quality of the research, and the credentials of the researcher) to help clinicians practice in situations where doubt may exist in the diagnosis, treatment, or prognosis of patients, will likely grow in importance. Evidence-based clinical practice guidelines and systematic literature reviews are manifestations of this trend. Historically, disease control measures and survival have been the primary and points in clinical cancer studies. Economic analyses and studies evaluating other end points (e.g., function, quality of life) will likely play a larger role in the future in evaluating the diagnosis, treatment, and follow-up of head, neck and other malignancies.

Economic analysis of the Confronting COPD survey: an overview of results.

An economic analysis of data from a large-scale international survey, Confronting COPD in North America and Europe, was conducted in seven countries (Canada, France, Italy, The Netherlands, Spain, the U.K and the U.SA.), to investigate the burden of chronic obstructive pulmonary disease (COPD). The results demonstrated the high economic impact of COPD on the healthcare system and society in each country. The mean annual direct costs of the disease were particularly high in the U.S.A. (US dollar 4119 per patient) and Spain (US dollar 3196 per patient) but relatively low in The Netherlands (US dollar 606) and France (US dollar 522). Lost productivity due to COPD had a particularly high impact on the economy in France, The Netherlands and the U.K, accounting for 67%, 50% and 41% of overall costs, respectively. The total societal cost of COPD per patient ranged from over US dollar 5646 in the U.S.A. to US dollar 1023 in The Netherlands. In five out of seven countries, the majority (52-84%) of direct costs associated with COPD were due to inpatient hospitalizations. As acute exacerbations of COPD are a key driver of secondary care costs, interventions aimed at preventing and treating exacerbations effectively could significantly reduce the economic impact of this disease. In all of the participating counties, COPD was underdiagnosed and undertreated. Between 9% and 30% of patients were undiagnosed despite having symptoms consistent with COPD, and up to 65% of patients did not receive regular prescribed medication. Patients reported poor symptom control and considerable use of healthcare resources. Therefore, reducing the burden of COPD will involve better evaluation and diagnosis of patients with COPD, as well as improved management of chronic COPD symptoms by healthcare professionals. The survey also demonstrated that the societal costs of COPD were 4-17 times higher in patients with severe COPD than in patients with mild COPD. Patients with comorbid conditions (accounting for 30-57% of patients in each country) were also particularly costly to society. These results suggest that a high priority should be given to interventions aimed at delaying the progression of disease, preventing exacerbations and reducing the risk of comorbidities, in order to alleviate the clinical and economic burden of COPD in North America and Europe.

Economics and health-related quality of life in antiemetic therapy: recommendations for trial design.

Emesis (nausea and vomiting) is one of the most important toxicities associated with chemotherapy. Although it is not life threatening, it has a major impact on a patient's health-related quality of life (HRQL) and overall response to chemotherapy. New antiemetics are expensive and well-conducted comparative health economic studies are rare. The aim of the study was to review the literature in the area of chemotherapy-induced emesis in cancer patients and to offer recommendations for the inclusion of these outcomes in the design of clinical trials for new antiemetic therapies. The economic literature was reviewed based on methodological standards for economic evaluation. Many studies did not comply with standards, specifically with regard to the choice of alternatives, chosen perspective, setting, type of emesis, measurement of costs and defining outcomes (including health-related quality of life). These issues are described for each study and recommendations for trial design are presented. The role of economic data is to support decision making in choosing between competing antiemetic therapies. It is the combination of clinical outcomes, costs and health-related quality of life, which will allow treating physicians to comprehensively assess the relative value of antiemetic therapies and to provide the most cost-effective therapy for their patients.
