Background: The clinical manifestations of atherothrombotic disease include ischaemic heart disease (including myocardial infarction [MI]) and cerebrovascular disease (including ischaemic stroke [IS]). Although costs generated by the clinical manifestations of atherothrombotic disease represent an important economic burden for any healthcare system, very few economic comparative data are available.Objective: To: (i) assess management costs of the different practice patterns for acute and chronic phases for MI, IS and peripheral arterial disease (PAD) in eight European countries; and (ii) to simulate the cost of managing a patient with an atherothrombotic disease for 2 years in Europe.Study Perspective: Healthcare system.Methods: Firstly, the medical costs of managing MI and IS were analysed during the acute phase and subsequent 6-month periods over a total of 2 years. In each case, a decision tree was designed to indicate resource use. Assumptions concerning patient management and resource use were based on currently available local and international literature, official national statistics and local expert opinions (Delphi panel). Costs were assessed using diagnosis-related groups (Austria, Italy, Portugal and Sweden), or hospital databases and national tariffs (Belgium, France, Spain and Switzerland). Secondly, these costs were correlated to data from a large randomised clinical trial to estimate the overall cost per patient with atherothrombotic disease over a 2-year period.Results: For MI, there was a 2-fold difference in costs between the eight countries (euro9512-18 293), with 47-76% of costs devoted to acute management, 14-48% to follow-up management during the first year, and 4-17% to follow-up during the second year. For IS, there was a 10-fold difference (euro5607-56 370), with 18-75% devoted to follow-up for the years 1995-1997.Conclusions: There are differences in the overall costs and cost breakdown in the clinical management patterns of MI and IS in Europe. These differences seem to arise as a result of local treatment pattern specificities as well as the availability of specific and well-adapted structures for patients' rehabilitation. Further studies are necessary to fully explain these differences. The assessment of the total medical costs of managing an atherothrombotic patient over a 2-year period (MI, IS, established PAD) has to take into account the risk of ischaemic events in different vascular areas (MI, IS or major leg ischaemia).

Introduction: Low molecular weight heparins are effective and have a good tolerability profile as first-line prophylaxis for venous thromboembolism (VTE) in major orthopaedic surgery. However, pharmacological inequivalence within the class could lead to differences in cost-effectiveness ratios.Objective: To quantify the potential economic impact of subcutaneous bemiparin sodium 3500 IU/day compared with enoxaparin sodium 40 mg/day as prophylaxis for VTE in patients undergoing total knee replacement (TKR) surgery, considering both in-hospital and post-discharge outcomes and costs during 6 weeks of postoperative follow-up.Methods: A cost-effectiveness analysis was performed using a decision modelling approach. The results were expressed in terms of costs and incremental cost effectiveness in Euro (2002 values). The treatment costs (hospital stay, physician services, drug administration) and costs incurred due to complications such as pulmonary embolism and/or proximal deep vein thrombosis, bleeding events, wound haematoma and thrombocytopenia were considered for this analysis. The target population comprised all adult patients undergoing TKR surgery included in a previous clinical trial (n = 381). The study was conducted in the setting of the Spanish National Health System. The time horizon chosen was 6 weeks.Results: Bemiparin provided cost savings of Euro144.48 per patient compared with enoxaparin when costs derived from treatment and complications during the 6-week postoperative period were considered (Euro4675.01 vs Euro4819.49). Pharmacy costs per patient were lower for bemiparin during hospital stay (Euro43.34 vs Euro50.20; difference, Euro-6.86) and for post-discharge prophylaxis (Euro68.63 vs Euro87.78; difference Euro-19.15). Bemiparin was calculated to avoid 42 additional VTE events per 1000 patients treated at 6 weeks. The incremental cost-effectiveness analysis indicated that bemiparin was dominant over enoxaparin, producing better outcomes and cost savings. The sensitivity analysis supported the cost effectiveness of bemiparin in all the ranges tested for complications and costs.Conclusions: Our model suggests, based on its underlying assumptions and data, that bemiparin may be more cost effective than enoxaparin for thromboprophylaxis in total knee replacement surgery in the Spanish healthcare setting.

Objective: To develop a user-friendly tool for managing the transfer of economic evaluation results.Methods: Factors that may influence the transfer of health economic study results were systematically identified and the way they impact on transferability was investigated. A transferability decision chart was developed that includes: knock-out criteria; a checklist based on the transferability factors; and methods for improving transferability and for assessing the uncertainty of transferred results. This approach was tested on various international cost-effectiveness studies in the areas of interventional cardiology, vaccination and screening.Results: The transfer of study results is possible pending the outcomes of the transferability check and necessary adjustments. Transferability factors can be grouped into areas of methodological, healthcare system and population characteristics. Different levels of effort are required for analysis of factors, ranging from very low (e.g. discount rate) to very high (e.g. practice variation). The impact of differences of most transferability factors can be estimated via the key health economic determinants: capacity utilisation, effectiveness, productivity loss and returns to scale. Depending on the outcomes of the transferability check a correction of the study results for inflation and for differences related to currencies or purchasing power might be sufficient. Otherwise, modelling-based adjustments might be necessary, requiring the (re-)building and sometimes structural modification of the study model. For determination of the most essential adjustments, a univariate sensitivity analysis seems appropriate. If not all relevant study parameters can be substituted with country-specific ones, multivariate or probabilistic sensitivity analysis seems to be a promising way to quantify the uncertainty associated with a transfer. If study results cannot be transferred, the transfer of study models or designs should be investigated as this can significantly save time when conducting a new study.Conclusions: Our transferability decision chart is a transparent and user-friendly tool for assessing and improving the transferability of economic evaluation results. A state of the art description of the methodology in a study, providing detailed components for calculation, is not only essential for determining its transferability but also for improving it via modelling adjustments.

Overactive bladder is a common condition, with recent findings estimating the prevalence in adults at about 15%. Symptoms, including urinary urgency, high voiding frequency and urge incontinence, have been shown to decrease patients' quality of life. Given its high prevalence, the economic burden of overactive bladder is also substantial, with a recent estimate placing the annual cost in the US at 9.1 billion US dollars (year 2000 values). The objective of this review is to provide a critical appraisal of published economic evaluations of pharmacological and non-pharmacological treatments for overactive bladder. Published economic evaluations of treatments for overactive bladder have focused entirely on pharmacological treatments -- mainly on the two most commonly used drugs, oxybutynin and tolterodine, each of which is available in immediate- and extended-release formulations. Ten economic evaluations (more than half are cost-effectiveness studies) have been published. Modelling with decision trees or Markov models has been the predominant method. Evaluations comparing drug therapy with no treatment have concluded that drug therapy is cost effective. Analyses comparing the formulations of oxybutynin and tolterodine have produced highly inconsistent results, largely due to the sources of data employed for effectiveness and treatment discontinuation rates. There are no evaluations of drugs relative to non-pharmacological treatment, and there are other significant gaps in the economic evaluations of treatment to date. These include gaps resulting from a lack of reliable data on the performance of these drugs in real-world settings, particularly data on long-term persistence with treatment. A more definitive pharmacoeconomic comparison of oxybutynin and tolterodine formulations, incorporating all available clinical data, and other treatment options would help direct treatment.

Introduction: Excellent treatment outcomes with long-term durability and few adverse effects are expectations of treatments for chronic conditions. The long-term cost effectiveness of newer treatments for benign prostatic hyperplasia (BPH), including high-energy transurethral microwave thermotherapy (TUMT) and combination pharmaceutical therapy, has not been sufficiently studied against existing alternatives. The objective of this study was to estimate the incremental cost effectiveness of BPH treatment alternatives.Methods: We employed a Markov model over a 20-year time horizon and the payer's perspective to evaluate the cost effectiveness of watchful waiting (WW), pharmaceuticals (alpha-adrenoceptor antagonists [alpha-blockers], 5-alpha-reductase inhibitors [5-ARIs], combination therapy), TUMT and transurethral resection of the prostate (TURP) in treating BPH. Markov states included improvement in symptoms, no improvement in symptoms, adverse effects and death. We used data from the published literature for outcomes, including systematic reviews whenever possible. Costs were estimated using a managed-care claims database and Medicare fee schedules, and were reported in Dollars US, 2004 values. Costs and effectiveness outcomes were discounted at a rate of 3% per year. Men (aged > or =45 years) with moderate to severe lower urinary tract symptoms and uncomplicated BPH were included in the analysis, and results were stratified by age and BPH symptom levels. Outcomes included costs, QALYs, incremental cost-utility ratios and cost-effectiveness acceptability curves. Sensitivity analysis was performed on important parameters, with an emphasis on probabilistic sensitivity analysis.Results: alpha-Blockers and TUMT were cost effective for treating moderate symptoms using the threshold of Dollars US 50,000 per QALY. For example, at 65 years of age, the cost per QALY was Dollars US 16,018 for alpha-blockers compared with WW and Dollars US 30,204 for TUMT versus alpha-blockers. TURP was the most cost-effective treatment for severe symptoms (Dollars US 5824 per QALY ) versus WW. Model results were robust to changes in costs and sensitive to the assumed probabilities, utility weights, extent of improvement and life expectancy. Nevertheless, acceptability curves consistently demonstrated the same alternatives as most likely to be cost effective.Conclusions: Our model suggests that alpha-blockers and TURP appear to be the most cost-effective alternatives, from a US payer perspective, for BPH patients with moderate and severe symptoms, respectively. TUMT was promising for patients with moderate symptoms and the oldest patients with severe symptoms, but otherwise was dominated. Value of information analysis could be used to determine the net benefit of additional research. [ABSTRACT FROM AUTHOR]

The aim of this paper was to conduct a critical systematic review of the available literature on the clinical and economic burden of bladder cancer in developed countries, with a focus on the cost effectiveness of interventions aimed at reducing that burden. Forty-four economic studies were included in the review. Because of long- term survival and the need for lifelong routine monitoring and treatment, the cost per patient of bladder cancer from diagnosis to death is the highest of all cancers, ranging from $US96 000–187 000 (2001 values) in the US. Overall, bladder cancer is the fifth most expensive cancer in terms of total medical care expenditures, accounting for almost $US3.7 billion (2001 values) in direct costs in the US. Screening for bladder cancer in the general population is currently not recommended. The economic value of relatively new and less expensive urine assays and molecular urinary tumour markers has not been assessed. However, the literature suggests that screening patients suspected of having bladder cancer and using less invasive diagnostic procedures is cost effective. Very few cost-effectiveness studies have evaluated intravesical therapies such as bacillus Calmette-Guérin and mitomycin in the management of superficial disease and no robust recommendations can be drawn. Economic analyses suggest that non-surgical treatment strategies for the management of invasive disease aiming at bladder preservation may not be cost effective, because they have not consistently demonstrated survival benefits and do not eliminate the need for subsequent radical cystectomy. The literature suggests that the current conventional frequent follow-up and monitoring of patients can be cost effectively replaced by less frequent and less invasive monitoring, and should rely more heavily on intravesical chemotherapy to reduce the need for cystoscopies. Bladder cancer is a fairly common and costly malignancy. Nevertheless, the existing literature only contributes marginally to our knowledge concerning the burden of bladder cancer and the economic value of various interventions. The limited value of the literature in this area may be attributed to (i) being published as abstracts rather than full peer-reviewed evaluations; (ii) employing questionable methodologies; and (iii) being in many cases nearly obsolete, rendering them less relevant to, if not in conflict with, current clinical practice. Consequently, opportunities exist to conduct meaningful economic research in all areas of the management of bladder cancer, including screening, diagnosis, follow-up and treatment, especially with respect to new and innovative pharmaceutical and other technologies.
