    ABSTRACT: Background Current management of rheumatoid arthritis (RA) focuses on inducing remission as early as possible to avoid lasting joint damage, and maintenance of remission has become important. A 12-month clinical trial in 834 patients with moderate RA investigated whether etanercept 50 mg/wk could be reduced to half dose or discontinued in patients who achieved low disease activity after 36 weeks. Objective The objective of this study was to estimate the cost-effectiveness of the three maintenance strategies. Methods A Markov model integrated the three strategies from the clinical trial and extrapolated to 10 years using data from the Swedish RA registry. Assumed treatment strategies after the trial were similar in all three arms, with patients failing to maintain remission on half-dose etanercept or methotrexate alone switching to the full dose of etanercept and patients maintaining remission on full-dose etanercept allowed switching to half dose. Resource use and utilities were taken from an observational study. Results are presented as cost/quality-adjusted life-year (QALY) (both discounted 3%) in the societal perspective. Results The cost/QALY gained with half-dose etanercept versus methotrexate ranged from €14,000 to €29,000: Longer simulations result in a higher cost/QALY, as the acquisition cost of etanercept increases. Half-dose etanercept technically dominates the full dose (lower costs [€−3000 to 6300] and similar effectiveness [0.007–0.011]). Conclusions Although ultimately all three strategies explored achieve a similar outcome as all three continuously manage patients to maintain remission, it appears that a dose reduction is the most advantageous strategy in patients with moderate disease activity.

    ABSTRACT: To evaluate the precision of the predictive cost-effectiveness assessment based on a phase 3 clinical trial with infliximab for the treatment of rheumatoid arthritis in Swedish clinical practice. Three patient cohorts were identified: the patients included in the infliximab trial (ATTRACT), patients initially treated with infliximab from a Swedish registry (STURE), a subset of these registry patients meeting inclusion criteria for the ATTRACT trial was the third patient cohort; two sets of assumptions in relation to the efficacy data were evaluated: "ATTRACT" (efficacy data over the duration of the trial) and "STURE" (effectiveness data over 10 years). In addition, the impact of including the placebo effect for the comparator was evaluated as a basis for the calculation of cost-effectiveness by using a modeling approach. A health economic model was utilized to estimate the cost per quality-adjusted life-year (QALY) gained. The results for the three patient cohorts ranged from cost saving to a cost per QALY gained of €2,400 and €24,900 to €26,000 when the ATTRACT and STURE assumptions were used, respectively. Sensitivity analyses indicated that the inclusion of placebo effect had the largest effect on the results, increasing the cost per QALY gained to approximately €50,000 for all patient cohorts. The treatment effect of infliximab measured in clinical trials and clinical practice results in comparable cost-effectiveness ratios, as calculated by using a modeling approach, whereas the assumptions made in relation to the effectiveness data and the chosen comparator have a large impact on the results. This reinforces the value of early modeling studies based on randomized clinical trial data, but assumptions made need to be carefully assessed.

    ABSTRACT: OBJECTIVE: The objective was to estimate the cost-effectiveness of TNF-inhibitors for the treatment of rheumatoid arthritis in Swedish clinical practice, both as a first and second biological treatment, with or without the combination of conventional DMARDs. Further sub-group analysis of etanercept treatment was performed. METHODS AND MATERIALS: Patient level data were obtained from three regions of the Swedish Rheumatology Registers. The dataset contained 2,558 patients who had started TNF-inhibitor treatment, 1,049 with etanercept as their first biological treatment. A total of 819 patients had switched to a second TNF-inhibitor, of which 425 to etanercept. A Markov cohort model was used in which health states of disease severity were classified according to HAQ and DAS28. Disease progression and discontinuation rates of TNF-inhibitors were based on the registry and for the comparator on published literature. Mortality, costs and utilities were based on Swedish data. The main analysis had a societal perspective over 20 years and efficacy was measured in quality-adjusted life-years (QALYs). RESULTS: TNF-inhibitor treatment was associated with an increase in QALYs and an incremental cost compared to no biological treatment. The cost per QALY gained with the three TNF-inhibitors ranged from 50,000 to 120,000, with lower estimates for TNF-inhibitors used in combination with MTX and as a first biologic. At a progression of 0.045 for the comparator, most values remain within the accepted range for cost-effectiveness. CONCLUSIONS: These results demonstrate that the cost per QALY for TNF-inhibitors was higher than in previous assessments based on registry data and that the results were sensitive to the HAQ progression of the comparator.

    ABSTRACT: BACKGROUND: The objective of this study was to evaluate the impact of rheumatoid arthritis (RA) on patients' sexuality and identify disease and other factors such as fatigue that most influence sexual relationships. METHODS: A specific pretested questionnaire was sent to all members of a French patient association (ANDAR). Questions related to demographics, disease status, quality of life (utility, EQ-5D), pain, psychological status (mood), fatigue and emotional and sexual relationships. To isolate the impact of RA, an attempt was made to include a matched sample from the general population. RESULTS: The analysis included 1271 patients, but only 70 controls agreed to participate and comparisons should therefore be considered with caution. The two groups were similar in terms of age, gender distribution, living conditions and diseases other than RA. However, patients scored worse for global health, mood, fatigue, had a lower utility (0.55 versus 0.65). Controls were more active sexually (69 % versus 63 %), in particular women (71 % versus 60 %). Age, gender, living alone, physical function and mood were significant predictors for being sexually active for patients; for controls, age and overall quality of life (utility) were significant predictors. CONCLUSIONS: While it is known that RA has a negative impact on patients' sexuality, there have been few attempts to quantify the problem. Our study highlights the negative impact of RA on patients' sexuality, and triggers the question how to include this aspect into care.

    ABSTRACT: Purpose. To describe treatment patterns among patients with central or branch retinal vein occlusion (CRVO or BRVO) in France, Germany, and Italy, and to estimate retinal vein occlusion (RVO)-related direct medical costs. Methods. We used a retrospective chart review to determine 18-month RVO-related resource utilization and calculate 12-month health care costs. Country-specific unit costs (€) were assigned to each resource from the perspective of the health care payer. Costs for France and Germany were based on 2005, and for Italy on 2007 values. Results. Data from a total of 109 BRVO and 119 patients with CRVO were used in the analysis. Laser therapy was the most commonly used intervention in Germany, for both CRVO and patients with BRVO (95%-98% of treatments), while patients in France with either condition had triamcinolone injections most often (63%-67% of treatments). Injections were also administered frequently in Italy and were the most common treatment for CRVO (50%), whereas patients with BRVO used laser therapy most often (41%). Inpatient treatment was most common in Germany (42% of CRVO and 34% of patients with BRVO), and did not occur at all in Italy except for day admissions. Total costs were higher for patients with CRVO in all countries. Most costs in Italy and France were attributable to outpatient treatment. In Germany, hospitalization made up the largest proportion of costs (80%), although more patients used outpatient services. Conclusions. Approaches to treating BRVO and CRVO vary across European countries. Development of agreed-upon guidelines would support consistency in patient care and reimbursement policy.

    ABSTRACT: Information about cost of multiple sclerosis (MS) is available from a number of European countries, but no data from the Czech Republic have been published so far. The objective of this study was to establish the cost of MS in the Czech Republic, overall and by level of disease severity. Data on demographics, disease history, resource consumption and production losses were collected from 909 patients recruited in 7 MS centres in the Czech Republic. Annual costs were estimated in the societal perspective, using 2007 unit costs. To evaluate the relationship between disability and costs, patients were stratified into those with mild (67%), moderate (27%) and severe (10%) disability using the Expanded Disability Status Scale. Mean total annual costs per patient were €12,272, of which 51% were direct medical costs, 4% direct non-medical costs and 45% indirect costs. The average annual costs in patients with mild, moderate and severe disability amounted to €9905, €14,064 and €22,880, respectively. The total costs of MS in the Czech Republic are estimated at €208.6 million per year. Consistent with other studies, the costs increase significantly with the severity of MS.

    ABSTRACT: The spectrum of disorders of the brain is large, covering hundreds of disorders that are listed in either the mental or neurological disorder chapters of the established international diagnostic classification systems. These disorders have a high prevalence as well as short- and long-term impairments and disabilities. Therefore they are an emotional, financial and social burden to the patients, their families and their social network. In a 2005 landmark study, we estimated for the first time the annual cost of 12 major groups of disorders of the brain in Europe and gave a conservative estimate of €386 billion for the year 2004. This estimate was limited in scope and conservative due to the lack of sufficiently comprehensive epidemiological and/or economic data on several important diagnostic groups. We are now in a position to substantially improve and revise the 2004 estimates. In the present report we cover 19 major groups of disorders, 7 more than previously, of an increased range of age groups and more cost items. We therefore present much improved cost estimates. Our revised estimates also now include the new EU member states, and hence a population of 514 million people. To estimate the number of persons with defined disorders of the brain in Europe in 2010, the total cost per person related to each disease in terms of direct and indirect costs, and an estimate of the total cost per disorder and country. The best available estimates of the prevalence and cost per person for 19 groups of disorders of the brain (covering well over 100 specific disorders) were identified via a systematic review of the published literature. Together with the twelve disorders included in 2004, the following range of mental and neurologic groups of disorders is covered: addictive disorders, affective disorders, anxiety disorders, brain tumor, childhood and adolescent disorders (developmental disorders), dementia, eating disorders, epilepsy, mental retardation, migraine, multiple sclerosis, neuromuscular disorders, Parkinson's disease, personality disorders, psychotic disorders, sleep disorders, somatoform disorders, stroke, and traumatic brain injury. Epidemiologic panels were charged to complete the literature review for each disorder in order to estimate the 12-month prevalence, and health economic panels were charged to estimate best cost-estimates. A cost model was developed to combine the epidemiologic and economic data and estimate the total cost of each disorder in each of 30 European countries (EU27+Iceland, Norway and Switzerland). The cost model was populated with national statistics from Eurostat to adjust all costs to 2010 values, converting all local currencies to Euro, imputing costs for countries where no data were available, and aggregating country estimates to purchasing power parity adjusted estimates for the total cost of disorders of the brain in Europe 2010. The total cost of disorders of the brain was estimated at €798 billion in 2010. Direct costs constitute the majority of costs (37% direct healthcare costs and 23% direct non-medical costs) whereas the remaining 40% were indirect costs associated with patients' production losses. On average, the estimated cost per person with a disorder of the brain in Europe ranged between €285 for headache and €30,000 for neuromuscular disorders. The European per capita cost of disorders of the brain was €1550 on average but varied by country. The cost (in billion €PPP 2010) of the disorders of the brain included in this study was as follows: addiction: €65.7; anxiety disorders: €74.4; brain tumor: €5.2; child/adolescent disorders: €21.3; dementia: €105.2; eating disorders: €0.8; epilepsy: €13.8; headache: €43.5; mental retardation: €43.3; mood disorders: €113.4; multiple sclerosis: €14.6; neuromuscular disorders: €7.7; Parkinson's disease: €13.9; personality disorders: €27.3; psychotic disorders: €93.9; sleep disorders: €35.4; somatoform disorder: €21.2; stroke: €64.1; traumatic brain injury: €33.0. It should be noted that the revised estimate of those disorders included in the previous 2004 report constituted €477 billion, by and large confirming our previous study results after considering the inflation and population increase since 2004. Further, our results were consistent with administrative data on the health care expenditure in Europe, and comparable to previous studies on the cost of specific disorders in Europe. Our estimates were lower than comparable estimates from the US. This study was based on the best currently available data in Europe and our model enabled extrapolation to countries where no data could be found. Still, the scarcity of data is an important source of uncertainty in our estimates and may imply over- or underestimations in some disorders and countries. Even though this review included many disorders, diagnoses, age groups and cost items that were omitted in 2004, there are still remaining disorders that could not be included due to limitations in the available data. We therefore consider our estimate of the total cost of the disorders of the brain in Europe to be conservative. In terms of the health economic burden outlined in this report, disorders of the brain likely constitute the number one economic challenge for European health care, now and in the future. Data presented in this report should be considered by all stakeholder groups, including policy makers, industry and patient advocacy groups, to reconsider the current science, research and public health agenda and define a coordinated plan of action of various levels to address the associated challenges. Political action is required in light of the present high cost of disorders of the brain. Funding of brain research must be increased; care for patients with brain disorders as well as teaching at medical schools and other health related educations must be quantitatively and qualitatively improved, including psychological treatments. The current move of the pharmaceutical industry away from brain related indications must be halted and reversed. Continued research into the cost of the many disorders not included in the present study is warranted. It is essential that not only the EU but also the national governments forcefully support these initiatives.

    ABSTRACT: To explore the cost-effectiveness of early biologic treatment, followed by dose-reduction in the case of remission, of active rheumatoid arthritis (RA), compared with standard treatment with methotrexate (MTX) in Sweden. Effectiveness (function, disease activity, erosions) in early RA for both alternatives was taken from a clinical trial comparing etanercept (ETA) combined with MTX to MTX alone. Patients discontinuing treatment can switch to another or their first biologic treatment. For patients in remission (Disease Activity Score [DAS28] < 2.6), ETA is reduced to half the dose. Return to full dose occurs when DAS28 reaches ≥ 3.2 again. Costs and utilities by level of functional capacity from an observational study are used. The model is analyzed as a micro-simulation and results are presented from the societal perspective for Sweden, for 10 years; costs (€2008) and effects are discounted at 3 percent. Sensitivity analysis was performed for the perspective, the time horizon, switching, and dose-reduction. The main analysis conservatively assumes 50 percent switching at discontinuation. The cost per quality-adjusted life-year (QALY) gained with early ETA/MTX treatment is €13,500 (societal perspective, incremental cost of €15,500 and incremental QALYs of 1.15). With 75 percent switching, the cost per QALY gained was €10,400. Over 20 years, the cost per QALY gained was €8,200. Results were further sensitive to the time patients remained on half dose and the perspective. CONCLUSIONS AND POLICY IMPLICATIONS: This study combines clinical trial and clinical practice data to explore cost-effective treatment scenarios in early RA, including the use of biologics. Our results indicate that a situation where a considerable proportion of patients achieve remission, dose-adjustments will increase the cost-effectiveness of treatment.

    ABSTRACT: To estimate the incremental costs to public payers for patients with ankylosing spondylitis (AS) of working age compared with reference subjects from the general population. We investigated total costs for 3 years (2005-2007) in 116 outpatients under 66 years of age with AS attending rheumatological care in Malmö, Sweden. Mean (SD) age was 46 (11) years and mean (SD) disease duration was 24 (11) years. Two subjects per AS patient matched for age, sex, and residential area were selected from the Population Register to serve as a reference group. We retrieved data concerning sick leave, prescription drugs, and healthcare consumption from Swedish health-cost registers by the unique personal identification numbers. The mean total cost for the 3-year period 2005-2007 was US $37,095 (SD $30,091) for patients with AS, and $11,071 (SD $22,340) for the reference group. The mean indirect cost was $19,618 and $5905, respectively. Mean cost for healthcare was $8998 for the AS patients and $4187 for the reference subjects, and mean cost for drugs was $8479 and $979, respectively. The patients with AS treated with biological therapy constituted 80% of the total drug cost, but just 40% of the cost for disability pension. Patients with AS had 3-fold increase in costs compared to reference subjects from the general population, and the drug costs were almost 10 times as high. Production losses (indirect cost) represented more than half of total cost (53%).

    ABSTRACT: To investigate long-term resource consumption and clinical outcome of patients with early primary open-angle glaucoma or ocular hypertension treated with prostaglandins in clinical practice in France. Thirty-four geographically spread specialized hospitals and private practices enrolled consecutive patients receiving, for the first time, a prostaglandin, alone or in combination. The study was based on routine practice and no consultations, examinations, or treatments were mandated by the protocol. Treating physicians recorded each consultation, including all examinations performed, referrals, admissions, and prescriptions. Descriptive analysis of resource consumption and development of intraocular pressure (IOP) and visual fields was performed, for all patients who completed the 4-year follow-up. The study enrolled 602 patients and 78% completed 4-year follow-up. Mean age was 65 years and mean time since diagnosis was 4 years. Mean IOP was reduced from a baseline of 21.2 mm Hg to 16.5 mm Hg during the first year and remained stable throughout the study. Mean visual fields at baseline were -4.2 mean deviation and stable during the follow-up. Total mean health care costs per patient were €1947, of which medication represented 50%. Over half of the patients (52%) remained on their initial medication during the 4 years. Drug changes were mostly because of inadequate IOP control and the number of treatment switches was significantly related to costs. This is the first prospective study of treatment with prostaglandins in clinical practice. The results indicate that many patients with early glaucoma managed primarily with prostaglandins will show very little progression over 4 years. Compared with the mid-90s, costs have not increased despite the higher acquisition cost of prostaglandins, as surgical interventions and medical consultations have decreased.

    ABSTRACT: To evaluate the long-term costs and quality of life (QoL) with and without disease-modifying treatments (DMTs) of patients with multiple sclerosis (MS). Data on resource consumption, productivity losses, QoL (utility), and fatigue were collected from 1355 patients registered with a patient association and descriptive analyses was performed.A Markov model was developed to estimate costs and utility over 20 years using the survey data. Disease progression without DMTs was taken from an epidemiological cohort in France (EDMUS cohort, LYON). Progression under DMTs was estimated from the Stockholm MS registry. Results are presented as cost per quality-adjusted life-years (QALYs), from the societal perspective, in EUR2007, discounted at 3%. Mean Expanded Disability Status Scale (EDSS) was 4.4 and mean total annual costs per patient were EUR44,400, of which 47% were productivity losses and 11% informal care. Public payers cover an estimated 48% of costs. Mean utility was 0.52, and the loss compared with the normal population was estimated at 0.28. Costs and utility ranged from EUR16,000 and 0.79 at EDSS 1 to EUR76,000 and 0.11 at EDSS 8-9.Over 20 years, costs were estimated at EUR429,000 and QALYs at 8.96 for patients without DMTs and at EUR433,207 and 9.24 QALYs if all patients were starting treated with DMTs at EDSS 1-3. Although the data for this analysis come from different sources, the results indicate that the cost increase with DMTs is moderate.

    ABSTRACT: The aim of this study was to estimate the cost-effectiveness of rituximab in patients not responding adequately to the first tumor necrosis factor (TNF) inhibitor using a model constructed to predict resource consumption and health outcomes in a population-based registry of biological treatments in Southern Sweden (SSATG). The model was developed as a discrete event simulation model, using SSATG data for the years 1999-2007. The data set included 1,903 patients with complete data on treatments (up to three treatment lines), functional capacity (HAQ), disease activity (DAS28), and utility (EQ-5D). Resource consumption was based on a regular population-based survey of patients in Southern Sweden. Rituximab was incorporated as second line treatment, using effectiveness data for the active group (N = 311) in a clinical trial comparing rituximab to placebo (REFLEX). It is thus compared to the mix of second line biologics used in SSATG. The analysis starts after failure of the first TNF inhibitor. Results are reported as costs (2008 euro) per quality-adjusted life-year (QALY; both discounted 3 percent), for the societal perspective in Sweden. Total costs in the rituximab strategy are estimated at 401,100 euro compared with 403,000 euro in the TNF-inhibitor arm. Total QALYs are 5.98 and 5.78, respectively. The findings were found to be robust in extensive sensitivity analysis. In our model, a strategy where rituximab is used as second line treatment after failure of the first TNF inhibitor provides a small saving (essentially due to the lower price of rituximab) and a QALY gain (due to better effect than the mix of second line TNF inhibitors).

    ABSTRACT: To design an economic model describing the costs and outcomes for patients treated with tumour necrosis factor alpha (TNFalpha) inhibitors for rheumatoid arthritis (RA) in current clinical practice in Sweden, to be used as a tool to estimate cost-effectiveness of the next generation of treatments. The model was constructed as a discrete event simulation (DES) model analysed at patient level. It contains treatment and outcome data for 1903 patients followed in the RA registry for biological drugs in southern Sweden between 1999 and 2007 [the Southern Swedish Arthritis Treatment Group (SSATG) Register]. Resource consumption was based on a survey of 1027 patients in the same region. Costs and quality-adjusted life years (QALYs) are presented for 10(5) years, for patients with the mean characteristics at treatment start in SSATG [Health Assessment Questionnaire (HAQ) score 1.33, disease duration 12.1 years, age 55 years], but also for patients with more or less severe disease. Cost and outcomes (QALYs) are discounted with 3%. The 10-year costs in the base case amount to USD 336,000 (SD USD 64,000) or EUR 223 000, with a total of 4.4 QALYs. Over 5 years, the costs amount to USD 208,000 or EUR 138,000 and QALYs to 2.5. The results were most sensitive to HAQ level at treatment start, but also to underlying disease progression, age, and disease duration. Starting treatment at a lower HAQ level (0.85) reduces costs by 10% and increase QALYs by 20%. This analysis is based on the longest available follow-up for patients treated with TNFalpha inhibitors and provides an opportunity to explore treatment strategies when new therapies become available using actual clinical practice data.

    ABSTRACT: To investigate resource consumption and quality of life (utility) in a sample of patients covering the full spectrum of the disease, modalities of patient management and geographic areas. Information on demographics, disease parameters, work capacity and resource consumption (in the past 1, 3 or 12 months depending on the resource) was collected in an anonymous mail survey from all members of a national patient association (ANDAR). Results are presented for the sample and by level of functional capacity, in 2005 euro. 1487 patients were included in the analysis (response rate 49%). Mean age was 62.7 years and 83.5% of respondents were female. Mean disease duration was 18 years; mean HAQ was 1.42; fatigue and pain ranked 5.6 and 4.8 on a scale between 0 and 10, respectively. Of patients below 60 years, 34% had taken early retirement due to RA, and only 15% of patients with a HAQ of 2 or higher were working. Productivity losses were estimated at 5076 euro, of which indemnity payments covered 1944 euro. Direct health care costs were 11,757 euro in the societal perspective and 9216 euro in the perspective of the national health insurance. Direct non-medical costs (including informal care) were 4857 euro and 136 euro respectively. Costs to society increased from 9400 euro in mild disease to 40,700 euro in severe disease, and to public payers from 6000 euro to 19,000 euro. Utility decreased simultaneously from 0.80 to 0.06. The study confirms overall findings in other studies in other countries, and provides the first estimate of all costs by disease severity in France.

    ABSTRACT: To estimate the cost-effectiveness of a new treatment (natalizumab) for multiple sclerosis (MS) compared with current standard therapy with disease-modifying drugs (DMDs) in Sweden. A Markov model was constructed to illustrate disease progression based on functional disability (the Expanded Disability Status Scale (EDSS)). The effectiveness of natalizumab was based on a 2-year clinical trial in 942 patients (AFFIRM). The effectiveness of current DMDs was estimated from a matched sample of 512 patients in the Stockholm MS registry. Patients withdrawing from treatment were assumed to follow the disease course of 824 patients with relapsing-remitting disease at onset in the Ontario natural history cohort. Costs and utilities are based on a recent observational study in 1339 patients. All data sets were available at the patient level. Main results are presented from the societal perspective, over a 20-year time frame, in 2005 Euros (euro1 = 9.25 SEK). In the base case, treatment with natalizumab was less expensive and more effective than treatment with current DMDs. When only healthcare costs were considered, the cost per quality-adjusted life year gained with natalizumab was euro38 145. Results are sensitive only to the time horizon of the analysis and assumptions about effectiveness of natalizumab beyond the trial. This cost-effectiveness analysis used registry data, cohort and observational studies to extrapolate the efficacy findings of natalizumab from the AFFIRM clinical trial to measure effectiveness in clinical practice. The analysis results suggest that for the population considered, natalizumab provides an additional health benefit at a similar cost to current DMDs from a societal perspective.
