The societal costs of problem gambling in Sweden.

BACKGROUND: Problem gambling is a public health issue affecting both the gamblers, their families, their employers, and society as a whole. Recent law changes in Sweden oblige local and regional health authorities to invest more in prevention and treatment of problem gambling. The economic consequences of gambling, and thereby the potential economic consequences of policy changes in the area, are unknown, as the cost of problem gambling to society has remained largely unexplored in Sweden and similar settings. METHODS: A prevalence-based cost-of-illness study for Sweden for the year 2018 was conducted. A societal approach was chosen in order to include direct costs (such as health care and legal costs), indirect costs (such as lost productivity due to unemployment), and intangible costs (such as reduced quality of life due to emotional distress). Costs were estimated by combining epidemiological and unit cost data. RESULTS: The societal costs of problem gambling amounted to 1.42 billion euros in 2018, corresponding to 0.30% of the gross domestic product. Direct costs accounted only for 13% of the total costs. Indirect costs accounted for more than half (59%) of the total costs, while intangible costs accounted for 28%. The societal costs were more than twice as high as the tax revenue from gambling in 2018. Direct and indirect costs of problem gambling combined amounted to one third of the equivalent costs of smoking and one sixth of the costs of alcohol consumption in Sweden. CONCLUSIONS: Problem gambling is increasingly recognized as a public health issue. The societal costs of it are not negligible, also in relation to major public health issues of an addictive nature such as smoking and alcohol consumption. Direct costs for prevention and treatment are very low. A stronger focus on prevention and treatment might help to reduce many of the very high indirect and intangible costs in the future.

Value of a QALY and VSI estimated with the chained approach.

The value of a quality-adjusted life-year (QALY) and the value of a statistical injury (VSI) are important measures within health economics and transport economics. Several studies have, therefore, estimated people's willingness to pay (WTP) for these estimates, but most results show scale insensitivity. The 'original' chained approach (CA) is a method developed to mitigate this problem by combining the contingent valuation (CV) with standard gamble (SG). In contrast to the version of the CA applied by the previous research of the WTP for a QALY, the original version allows the value of major health gains to be estimated without having the respondents express their WTP directly. The objective of this study was to estimate the value of a QALY and VSI in the context of non-fatal road traffic accidents using the original CA to test if the approach, applied to a wide range of health gains, is able to derive valid estimates and a constant value of a QALY which the previous research has not been able to show. Data were collected from a total of 800 individuals in the Swedish adult general population using two web-based questionnaires. The values of a QALY based on trimmed estimates were close to constant at €300,000 irrespective of the size of the QALY gain. The study shows that the original CA method may be a valid method to estimate the value of a QALY and VSI for major health losses. It also supports the use of a higher threshold value for a QALY than that which is currently applied by several health technology assessment agencies in different countries.

Measuring the end-of-life premium in cancer using individual ex ante willingness to pay.

For the assessment of value of new therapies in healthcare, Health Technology Assessment (HTA) agencies often review the cost per quality-adjusted life-year (QALY) gained. Some HTA agencies accept a higher cost per QALY gained when treatment is aimed at prolonging survival for patients with a short expected remaining lifetime, a so-called end-of-life (EoL) premium. The objective of this study is to elicit the existence and size of an EoL premium in cancer. Data was collected from 509 individuals in the Swedish general population 20-80 years old using a web-based questionnaire. Preferences were elicited using subjective risk estimation and the contingent valuation (CV) method. A split-sample design was applied to test for order bias. The mean value of a QALY was MSEK4.8 (€528,000), and there was an EoL premium of 4-10% at 6 months of expected remaining lifetime. Using subjective risk resulted in more robust and valid estimates of the value of a QALY. Order of scenarios did not have a significant impact on the WTP and the result showed scale sensitivity. Our result provides some support for the use of an EoL premium based on individual preferences when expected remaining lifetime is short and below 24 months. Furthermore, we find support for a value of a QALY that is above the current threshold of several HTA agencies.

Social/economic costs and health-related quality of life in patients with juvenile idiopathic arthritis in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with juvenile idiopathic arthritis (JIA) in Europe. METHODS: We conducted a cross-sectional study of patients with JIA from Germany, Italy, Spain, France, the United Kingdom, Bulgaria, and Sweden. Data on demographic characteristics, healthcare resource utilization, informal care, labor productivity losses, and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D-5L) questionnaire. RESULTS: A total of 162 patients (67 Germany, 34 Sweden, 33 Italy, 23 United Kingdom, 4 France, and 1 Bulgaria) completed the questionnaire. Excluding Bulgarian results, due to small sample size, country-specific annual health care costs ranged from €18,913 to €36,396 (reference year: 2012). Estimated direct healthcare costs ranged from €11,068 to €22,138; direct non-healthcare costs ranged from €7837 to €14,155 and labor productivity losses ranged from €0 to €8715. Costs are also shown to differ between children and adults. The mean EQ-5D index score for JIA patients was estimated at between 0.44 and 0.88, and the mean EQ-5D visual analogue scale score was estimated at between 62 and 79. CONCLUSIONS: JIA patients incur considerable societal costs and experience substantial deterioration in HRQOL in some countries. Compared with previous studies, our results show a remarkable increase in annual healthcare costs for JIA patients. Reasons for the increase are the inclusion of non-professional caregiver costs, a wider use of biologics, and longer hospital stays.

Budget impact analysis of surgical treatment for obesity in Sweden.

BACKGROUND: The recent substantial increase in the number of obese surgeries performed in Sweden has raised concerns about the budget impact. OBJECTIVE: Our aim in this paper is to present an assessment of the budgetary impact of different policies for surgical intervention for obese and overweight subjects from a healthcare perspective in Sweden. METHODS: The model simulates the annual expected treatment costs of obesity related diseases and surgery in patients of different sex, age and Body Mass Index (BMI). Costs evaluated are costs of surgery plus the excess treatment costs that an obese patient has over and above the treatment costs of a normal-weight patient. The diagnoses that are included for costs assessment are diabetes and cardiovascular disease since these diagnoses are the principal diagnoses associated with obesity. Four different scenarios over the number of surgical operations performed each year are simulated and compared: (1) no surgical operation, (2) 3 000 surgical operations in persons with BMI > 40, (3) 4 000 (BMI > 40), and (4) 5 000 (expanded to BMI > 38). RESULTS: Comparing Scenario 2 with Scenario 1 results in a net budget impact of on average SEK 121 million per annum or SEK 40 000 per patient. This implies that 55 percent of the cost of surgery, set equal to SEK 90 000 for each patient, has been offset by a reduction in the excess treatment costs of obesity related diseases. Expanding annual surgery from 3000 to 4000 the cost-offset increased to 58%. By expanding annual surgery further from 4000 to 5000 and at the same time expanding the indication for surgery from BMI > 40 to BMI > 38, no cost-offset is obtained. CONCLUSION: A cost-minimization strategy for bariatric surgery in Sweden should not expand indication, but rather increase the number of surgeries within the currently accepted indication.

Drug and treatment costs in Parkinson's disease patients in Sweden.

BACKGROUND: Parkinson's disease (PD) is a chronic neurodegenerative disease expected to cause great costs. The aim of this study was to calculate drug and treatment costs in patients with PD in Sweden. METHOD: All healthcare contacts of patients with PD in Stockholm County, Sweden, were extracted from registers together with information on reimbursements from the authorities to the caregivers. PD-related costs were calculated together with non-PD-related costs. Cost per patient was calculated and extrapolated to the whole Swedish population, taking population demographics into consideration. In addition, nationwide PD drug sales statistics were included. RESULTS: The PD prevalence of Stockholm County was estimated to 196 per 100,000 inhabitants, resulting in an estimated total of about 22,000 patients with PD in Sweden. The cost per patient was estimated to SEK 76,000 of which drug costs accounted for SEK 15,880. The annual direct costs in patients with PD in Sweden were SEK 1.7 billion in 2009. CONCLUSION: Our study estimates high direct costs in patients with PD in Sweden, SEK 1.7 billion, 52% for inpatient care, 27% for outpatient care and 21% for drugs. With an ageing population and the medical progress, the financial burden on society will most probably increase in the future. This study might initiate and provide information for discussions about future cost allocations and healthcare priorities.

Practical issues in handling data input and uncertainty in a budget impact analysis.

The objective of this paper was to address the importance of dealing systematically and comprehensively with uncertainty in a budget impact analysis (BIA) in more detail. The handling of uncertainty in health economics was used as a point of reference for addressing the uncertainty in a BIA. This overview shows that standard methods of sensitivity analysis, which are used for standard data set in a health economic model (clinical probabilities, treatment patterns, resource utilisation and prices/tariffs), cannot always be used for the input data for the BIA model beyond the health economic data set for various reasons. Whereas in a health economic model, only limited data may come from a Delphi panel, a BIA model often relies on a majority of data taken from a Delphi panel. In addition, the dataset in a BIA model also includes forecasts (e.g. annual growth, uptakes curves, substitution effects, changes in prescription restrictions and guidelines, future distribution of the available treatment modalities, off-label use). As a consequence, the use of standard sensitivity analyses for BIA data set might be limited because of the lack of appropriate distributions as data sources are limited, or because of the need for forecasting. Therefore, scenario analyses might be more appropriate to capture the uncertainty in the BIA data set in the overall BIA model.

Preserving the world's tropical forests--a price on carbon may not do.

Climate policy will create both disincentives and incentives for tropical deforestation. Disincentives if the carbon emissions from forest clearing are priced, as is currently being discussed within the United Nations Framework Convention on Climate Change (UNFCCC); incentives as a price on carbon will increase the demand for carbon-neutral energy sources, including bioenergy, making deforestation for biomass cultivation increasingly profitable. The question is whether the increased cost for forest clearing, through the price on carbon emissions, will be enough to counter-balance the increased profitability of deforestation through the escalating value of agricultural land. In an attempt to answer this question we analyze the profitability of tropical deforestation and subsequent bioenergy production, taking oil palm plantations as an illustrative example. We estimate that deforesting for palm oil bioenergy production is likely to remain highly profitable, even in the face of a price on the carbon emissions from forest clearing. Current efforts to include carbon emissions from tropical deforestation in a future international climate regime, while a step in the right direction, may therefore not suffice as protection for the world's tropical forests. Additional, and stronger, protection measures for the world's tropical forests will still be needed.

Costs associated with blood transfusions in Sweden--the societal cost of autologous, allogeneic and perioperative RBC transfusion.

Anaemia is characterised by an insufficient number of red blood cells (RBCs) and might occur for different reasons, e.g. surgical procedures are often with associated blood loss. Patients who suffer from anaemia have the option of treatment with blood transfusion or medical treatment. In this study, the societal cost, for the case of Sweden, of RBC transfusion using three different techniques, i.e. allogeneic, autologous and intraoperative transfusion, was estimated. The analysis was based on information from interviews with hospital staff at large Swedish hospitals and from published data. The average cost for a 2 units transfusion was found to be Swedish kronor (SEK) 6330 (702 Euro) for filtered allogeneic RBCs and SEK 5394 (598 Euro) for autologous RBCs for surgery patients. Transfusion reactions accounted for almost 35 per cent of the costs of allogeneic RBC transfusions. The administration cost was found to be much higher for autologous transfusions compared with allogeneic transfusions. The cost of intraoperative erythrocyte salvage was calculated to be SEK 2567 (285 Euro) per transfusion (>4 units).

Cost-effectiveness analysis of inhaled corticosteroids in asthma: a review of the analytical standards.

PURPOSE: To determine whether published cost-effectiveness studies on inhaled corticosteroids (ICS) in asthma adhered to basic analytical standards as defined in health economic textbooks and in guidelines assessing and comparing efficacy and safety. METHODS: Original cost-effectiveness studies published between 1990 and 2000 in general medical or economic journals were reviewed to assess the adherence to five fundamental methodological principles: (1) design of the study, (2) choice of perspective and corresponding costs, (3) choice of outcome measure, (4) marginal cost analysis, and (5) sensitivity analysis and discussion about external validity. For each principle, the studies were ranked as high, medium or low quality. RESULTS: Most of the 18 studies included were ranked medium on the first two principles. The studies adhered to a higher degree to the remaining three principles. Only three studies were high ranked in all five principles. The number of principles fulfilled increased over time. Studies comparing pharmaceutical products from competing companies were typically short-term studies, designed for other purposes than health economic analyses, and, in general, did not use therapeutically equivalent dosing. CONCLUSIONS: Attention should be drawn to the study design, the weak correspondence between perspective and costs, and especially to the impact of bias in health economic results when comparing different doses of ICSs.

Cost-effectiveness of treating deep diabetic foot ulcers with Promogran in four European countries.

OBJECTIVE: This study aimed to estimate the cost-effectiveness of treating non-superficial diabetic foot ulcers with Promogran plus good wound care (GWC) compared with GWC alone in four European countries (France, Germany, Switzerland and UK). METHODS: An existing Markov-based health economic model of non-superficial diabetic foot ulcers was adapted to incorporate the relative efficacy of Promogran compared with GWC alone as demonstrated in a randomised controlled trial. Treatment with Promogran was modelled for a maximum of three months. Country-specific treatment costs were used to estimate the incremental cost per ulcer-free day gained over 12 months. Some parameter assumptions were changed to assess the sensitivity of the results. RESULTS: Within the first three months of treatment, 26% of ulcers in the Promogran cohort healed compared with 20.7% in the GWC cohort. Over the 12 months, the average number of months spent in the healed state was 3.41 (GWC) and 3.75 (Promogran). Promogran treatment was found to be cost-saving in all four countries, using year 2000 Euro values. CONCLUSION: Promogran with GWC may be cost-effective, perhaps even cost-saving, under a wide variety of assumptions for the treatment of neuropathic foot ulcers. DECLARATION OF INTEREST: This study was funded by Ethicon Gmbh (Johnson and Johnson), Germany.

Costs for screening, intervention and hospital treatment generated by the Malmö Preventive Project: a large-scale community screening programme.

OBJECTIVES: The purpose of this study was to estimate retrospectively the costs of health care resources used in the Malmö Preventive Project, Sweden and estimate the costs of in-patient care that were avoided because of early intervention. SETTING AND SUBJECTS: A large-scale community intervention programme was conducted from 1974 to 1992 in Malmö, Sweden with the aim of reducing morbidity and mortality of cardiovascular diseases (CVD), alcohol related illnesses, and breast cancer. Between 1974 and 1992, 33 336 male and female subjects were screened for hypertension, hyperlipidaemia, type-2 diabetes and alcohol abuse. Intervention programmes that included life-style modifications, follow-up visits with physicians and nurses and drug therapy were offered to about 25% of screened subjects. METHODS: Recruitment costs were generated through out the screening period. Intervention costs were estimated for 5 years after screening. Excess in-patient care costs were estimated by subtracting hospital consumption for an unscreened, matched cohort from that of the screened cohort over follow-up periods of 13-19 years. Intervention and excess in-patient care costs were estimated until 1996. RESULTS: The net expenditures for recruitment and intervention was SEK253 million and saved costs for in-patient care of SEK143 millions (1998 prices). Considering the opportunity cost of the resources used in the study, the net cost rises to about SEK200 millions. CONCLUSIONS: The results suggest that only part of the intervention costs were offset by reduction in future morbidity health care costs. This is in line with results from prospective analyses of other primary prevention programmes.

Cost effectiveness of Becaplermin in the treatment of diabetic foot ulcers in four European countries.

OBJECTIVE: The primary objective of this study was to estimate the cost effectiveness of treating diabetic foot ulcers with becaplermin (Regranex) plus good wound care (GWC) compared with GWC alone in a variety of European healthcare settings. A secondary objective was to analyse the effect of different treatment practices on the economics of caring for diabetic foot ulcers. DESIGN AND SETTING: Markov-based simulation study from the perspective of a national health system. METHODS: A 12-month Markov computer simulation model was used to assess the cost effectiveness in 4 European countries of treating diabetic foot ulcers with becaplermin plus GWC versus GWC alone. Transition probabilities were taken from a prospective study of 183 patients and becaplermin efficacy was based on 20-week healing rates in a recent meta-analysis of clinical trials involving 449 patients. Country-specific treatment cost data were collected in collaboration with local economic consultations and combined with the disease model to estimate the incremental cost per ulcer-free month gained. The model was then run using hypothetical low- and high-intensity resource usage profiles to investigate the economics of caring for diabetic foot ulcers. RESULTS: Over the course of 1 year, individuals who received becaplermin plus GWC were, on average, predicted to spend an additional 0.81 months (24% longer) free of ulcers and to experience a 9% lower risk of undergoing a lower extremity amputation than individuals who received GWC alone. Consequently, becaplermin plus GWC was estimated to be net cost saving in Sweden, Switzerland and the UK. In France, the addition of becaplermin was estimated to add $US19 (1999 values) for each additional ulcer-free month gained. There were substantial intercountry differences in treatment practices and the costs of treating diabetic foot ulcers. CONCLUSIONS: Becaplermin may be a cost-effective treatment for neuropathic diabetic foot ulcers in a wide range of European settings. In Sweden, Switzerland and the UK, becaplermin may even be cost saving. Substantial intercountry differences in resource patterns appear, at least partly, to be the logical outcome of differences in unit costs.

Scope and scale insensitivities in a contingent valuation study of risk reductions.

A contingent valuation study asking willingness to pay (WTP) for reducing the overall death risk as well as the risk for fatal and non-fatal injuries in road traffic accidents was performed in Sweden 1998. Different sub-samples were used to test for scale (different risk reductions) and scope (different outcomes) effects, existence of which implies that a respondent is capable of differentiating a WTP-answer accordingly. The results indicated that respondents needed some reference point for their valuation. For instance, dependent samples showed, contrary to independent ones, a significant difference between WTP of dying from any cause and in a traffic accident for the same relative but different absolute risk reduction. Regarding non-fatal traffic accidents, tests were performed comparing valuation of risk reductions for injuries with different outcomes but identical baseline risks and relative risk reductions. Similar to the case above, dependent samples differentiated their WTP and were willing to pay significantly more for a severe injury than for a slight one, which was not the case for independent samples.

A 1-year cost-effectiveness model for the treatment of chronic schizophrenia with acute exacerbations in Belgium.

OBJECTIVE: A 1-year semi-Markov model was constructed to simulate the cost-effectiveness of atypical and typical antipsychotic treatments for schizophrenia. METHODS: The core model comprised nine 6-week cycles and includes events such as survival, response, adverse events, and compliance. The nature, duration, intensity, and timing of adverse events were incorporated. Compliance was modeled as a function of health state, time, and adverse events. Three first-line treatments were considered (risperidone, olanzapine, and haloperidol oral) and the transition probabilities of switching between five different therapies (haloperidol oral, haloperidol depot, risperidone, olanzapine and clozapine) were included. Effectiveness was modeled based on a modified method of TWiST (time without symptoms and toxicity). The direct costs of utilization of medical resources are taken into account, including five different patient care settings, consultations, neuroleptic medication, laboratory tests, and treatment of side-effects. RESULTS: This paper reports the methodology used to construct the model and the results obtained when it was applied to the treatment of patients with schizophrenia in the Belgian health care system. CONCLUSIONS: Over the study period, risperidone and olanzapine were more cost-effective than haloperidol and of the two major atypical drugs, risperidone was the more cost-effective.

The cost-effectiveness of treating diabetic lower extremity ulcers with becaplermin (Regranex): a core model with an application using Swedish cost data.

OBJECTIVES: The objective of this study was to develop a model capable of assessing the cost-effectiveness in Sweden of treating diabetic neuropathic lower extremity ulcers with becaplermin gel (Regranex) plus good wound care (GWC) relative to treating them with GWC alone. METHODS: A Markov simulation model was developed that includes six health states: Uninfected Ulcer, Infected Ulcer, Gangrene, Healed Ulcer, Healed Ulcer-History of Amputation, and Deceased. To predict clinical outcomes, information was taken from a specially designed prospective 9-month follow-up study of 183 neuropathic patients in the US treated with GWC. Cost of treatment data were taken primarily from a study of a cohort of 314 patients in Sweden. The efficacy of becaplermin was assumed equal to that achieved in a pooled analysis of four randomized clinical trials. A model application provides expected clinical outcomes for a cohort of patients. Annual treatment costs per patient were estimated using treatment practice and unit prices from Sweden. RESULTS: Due to a higher rate of healing and a shorter average healing time, treatment with becaplermin gel was predicted to increase the average number of months spent in the healed state over the first year following development of an ulcer by 24% relative to GWC alone. In addition, the corresponding number of amputations was 9% lower for the becaplermin-treated cohort. The average expected cost of $12,078 US for an individual treated with GWC alone declines to $11,708 US for one treated with becaplermin, in spite of $1262 becaplermin costs. Expenses related to topical treatment and inpatient care account for 83% of the resources conserved. CONCLUSIONS: Our results suggest that in Sweden treatment with becaplermin in conjunction with GWC consumes fewer resources and generates better outcomes than treatment with GWC alone for diabetic neuropathic ulcers. In light of the high and increasing incidence of such ulcers, the potential savings in costs and suffering may be important. Results are difficult to extrapolate internationally because they are strongly related to country-specific treatment practices and price levels.
