Budget impact analysis of adjunctive therapy with lacosamide for partial-onset epileptic seizures in Belgium

Summary

Objective:

This study aims to compute the budget impact of lacosamide, a new adjunctive therapy for partial-onset seizures in epilepsy patients from 16 years of age who are uncontrolled and having previously used at least three anti-epileptic drugs from a Belgian healthcare payer perspective.

Methods:

The budget impact analysis compared the ‘world with lacosamide’ to the ‘world without lacosamide’ and calculated how a change in the mix of anti-epileptic drugs used to treat uncontrolled epilepsy would impact drug spending from 2008 to 2013. Data on the number of patients and on the market shares of anti-epileptic drugs were taken from Belgian sources and from the literature. Unit costs of anti-epileptic drugs originated from Belgian sources. The budget impact was calculated from two scenarios about the market uptake of lacosamide.

Results:

The Belgian target population is expected to increase from 5333 patients in 2008 to 5522 patients in 2013. Assuming that the market share of lacosamide increases linearly over time and is taken evenly from all other anti-epileptic drugs (AEDs), the budget impact of adopting adjunctive therapy with lacosamide increases from €5249 (0.1% of reference drug budget) in 2008 to €242,700 (4.7% of reference drug budget) in 2013. Assuming that 10% of patients use standard AED therapy plus lacosamide, the budget impact of adopting adjunctive therapy with lacosamide is around €800,000–900,000 per year (or 16.7% of the reference drug budget).

Conclusions:

Adjunctive therapy with lacosamide would raise drug spending for this patient population by as much as 16.7% per year. However, this budget impact analysis did not consider the fact that lacosamide reduces costs of seizure management and withdrawal. The literature suggests that, if savings in other healthcare costs are taken into account, adjunctive therapy with lacosamide may be cost saving.     

Burden of rotavirus gastroenteritis and potential benefits of a pentavalent rotavirus vaccination in Belgium

Abstract

Objective and Methods: A decision analytic model was built to assess the paediatric rotavirus gastroenteritis (RVGE) burden and potential benefits associated with the introduction of RotaTeq^®? (pentavalent rotavirus vaccine) in Belgium.

Results: In the absence of a rotavirus (RV) immunisation programme, paediatric RVGE was estimated to account for about 5,860 hospitalisations, 1,720 cases of nosocomial infections, 9,410 cases treated by general practitioners/paediatricians (GP/P) and 10,790 cases not seeking medical care for a birth cohort followed up to 5 years of age. Paediatric RVGE was estimated to cost about €9.0 million from the Belgian healthcare provider perspective and €15.3 million to society. Given a 90% RV vaccination coverage rate, the pentavalent RV vaccine would have a high impact on RV burden by preventing more than 4,850 hospitalisations, 995 cases of nosocomial infections, 7,145 cases treated by GP/P and 8,190 cases not seeking medical care, and reduce RVGE costs by €7.1 million from the Belgian healthcare provider perspective and €12.0 million to society.     

Economic burden associated with the management of cervical cancer,cervical dysplasia and genital warts in Belgium

Abstract

Objective: Human papillomavirus (HPV) infections can lead to cervical intraepithelial neoplasia (CIN) lesions, cervical cancer (CC) and genital warts (GWs). This study intended to assess the annual cost of CC, CIN and GW management in Belgium.

Method: A retrospective study using a Belgian Hospital Disease Database (for yearly hospital cost of CC and GW patients) and a clinical expert survey were performed to assess the medical management of CC, CIN and GW patients. Belgian official sources were used to estimate the annual costs of management of CC, CIN and GW patients both from a healthcare payer perspectives (HCPP) and a societal perspective.

Results: Based on the 667 patients diagnosed annually in Belgium with CC and an annual cost per patient of €9,716, the total annual cost of CC is €6.5 million (HCPP). The 10,495 estimated CIN 1, 2 and 3 patients led to an annual cost of €1.97 million (HCPP). The 7,989 estimated annual number of diagnosed GW patients led to an estimated annual cost of €2.53 million (HCPP).

Conclusion: HPV-related diseases represent an important burden on Belgian society, especially when considering that the estimates in this study are probably underestimations, as the management costs of other HPV-related diseases (vulvar, vaginal, penile, oropharyngeal (pre-) cancers, recurrent respiratory papillomatosis etc.) are not included in this analysis.     

Health economic evaluation of a vaccine for the prevention of herpes zoster (shingles) and post-herpetic neuralgia in adults in Belgium

Abstract

Objective:

To determine the cost-effectiveness of vaccination against herpes zoster (HZ) and post-herpetic neuralgia (PHN) in individuals aged 60 years and older in Belgium.

Methods:

A Markov model was developed to compare the cost-effectiveness of vaccination with that of a policy of no vaccination. The model estimated the lifetime incidence and consequences of HZ and PHN using inputs derived from Belgian data, literature sources, and expert opinion. Cost-effectiveness was measured by the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life-year (QALY) gained.

Results:

Vaccination in individuals aged 60 years and older resulted in ICERs of €6,799 (third party payer perspective), €7,168 (healthcare perspective), and €7,137 (societal perspective). The number needed to vaccinate to prevent one case was 12 for HZ, and 35 or 36 for PHN depending on the definition used. Univariate sensitivity analyses produced ICERs of €4,959–19,052/QALY; duration of vaccine efficacy had the greatest impact on cost-effectiveness. Probabilistic sensitivity analysis showed at least a 94% probability of ICERs remaining below the unofficial €30,000 threshold.

Discussion:

Key strengths of the model are the combination of efficacy data from a pivotal clinical trial with country-specific epidemiological data and complete sensitivity analysis performed. Main limitations are the use of non country-specific PHN proportion and non Belgian disease-specific utilities. Results are comparable with those recently published.

Conclusions:

HZ vaccination in individuals aged 60 years and older would represent a cost-effective strategy in Belgium.     

Cost-effectiveness of dabigatran etexilate in the prevention of stroke and systemic embolism in patients with atrial fibrillation in Belgium

Abstract

Objective:

To assess the cost-effectiveness of dabigatran etexilate (‘dabigatran’) vs vitamin K antagonists (VKAs) in the Belgian healthcare setting for the prevention of stroke and systemic embolism (SE) in patients with non-valvular atrial fibrillation (AF).

Research design and methods:

A Markov model was used to calculate the cost-effectiveness of dabigatran vs VKAs in Belgium, whereby warfarin was considered representative for the VKA class. Efficacy and safety data were taken from the Randomized Evaluation of Long-Term Anticoagulation Therapy (RE-LY) trial and a network meta-analysis. Local resource use and unit costs were included in the model. Effectiveness was expressed in Quality Adjusted Life-Years (QALYs). The model outcomes were total costs, total QALYs, incremental costs, incremental QALYs and the incremental cost-effectiveness ratio (ICER). The level of International Normalized Ratio (INR) control and the use of other antithrombotic therapies observed in Belgian clinical practice were reflected in two scenario analyses.

Results:

In the base case analysis, total costs per patient were €13,333 for dabigatran and €12,454 for warfarin. Total QALYs per patient were 9.51 for dabigatran and 9.19 for warfarin. The corresponding ICER was €2807/QALY. The ICER of dabigatran was €970/QALY vs warfarin with real-world INR control and €5296/QALY vs a mix of warfarin, aspirin, and no treatment. Results were shown to be robust in one-way and probabilistic sensitivity analyses.

Limitations:

The analysis does not include long-term costs for clinical events, as these data were not available for Belgium. As in any economic model based on data from a randomized clinical trial, several assumptions had to be made when extrapolating results to routine clinical practice in Belgium.

Conclusion:

This analysis suggests that dabigatran, a novel oral anticoagulant, is a cost-effective treatment for the prevention of stroke and SE in patients with non-valvular AF in the Belgian healthcare setting.     

A cost-effectiveness and budget impact analysis of apremilast in patients with psoriatic arthritis in Italy

Abstract

Aims: The aim of this study was to conduct a cost-effectiveness analysis, as well as a budget impact analysis, on the use of apremilast for the treatment of adult patients with psoriatic arthritis (PsA), within the Italian National Health Service (NHS).

Methods: A Markov state transition cohort model, which was adapted to the Italian context, was used to compare the costs of the currently available treatments and of the patients’ quality of life with two alternative treatment sequences, with or without apremilast as pre-biologic therapy. Moreover, a budget impact model was developed based on the population of patients treated for PsA in Italy, who can be eligible for treatment with apremilast. The eligible population was represented by adult patients with PsA who had an inadequate response to or were intolerant to previous disease-modifying antirheumatic drugs (DMARDs), for the approved indication, and for the treatment studied in the economic analytic model.

Results: This cost-effectiveness analysis estimated that the strategy of using apremilast before biologic therapy is cost-effective, with an incremental cost-effectiveness ratio of €32,263.00 per QALY gained which is slightly over the normal threshold found in other Italian economic studies, which usually considers a 40-year-period. Conversely, the budget impact analysis was conducted over 3?years, and it led to an estimated annual saving of €1.6 million, €4.6 million and €5.5 million in the first, second and third year of apremilast commercialization, respectively, for a total saving of €11.75 million in 3?years.

Limitations: Limitations of this analysis include the absence of head-to-head trials comparing therapies included in the economic model, the lack of comparative long-term data on treatment efficacy, and the assumption of complete independence between the considered response rates to therapy.

Conclusion: The use of apremilast as a first option before the use of biologic agents may represent a cost-effective treatment strategy for patients with PsA who fail to respond to, or are intolerant to, previous DMARD therapy. In addition, based on a budget impact perspective, the use of apremilast may lead to cost savings to the Italian healthcare system.     

Cost-effectiveness analysis of clopidogrel versus aspirin in patients with atherothrombosis based on the CAPRIE trial

SUMMARY

Clopidogrel has been shown to reduce the secondary risk of ischaemic events in vascular disease compared to aspirin. This article compares the economics of the two drugs for this condition, by providing an incremental cost-effectiveness ratio (iCER) of clopidogrel versus aspirin, using Belgium as a case setting.

A 2 year Markov model, in which patients with vascular disease were assumed to receive either clopidogrel or aspirin, was developed from a healthcare payer's perspective. Survival data were based on the Saskatchewan Health database. Costs included treatment and adverse events. Cost-effectiveness was expressed as the cost per life year gained (LYG).

The iCER of clopidogrel versus aspirin was €13,390/LYG (95% CI: €6,990; €26,470). The robustness of these results was shown by univariate and probabilistic sensitivity analyses.

This analysis shows that clopidogrel is cost-effective for the secondary prevention of ischaemic events in the Belgian setting.     

Evaluation of cost savings with ferric carboxymaltose in anemia treatment through its impact on erythropoiesis-stimulating agents and blood transfusion: French healthcare payer perspective

Abstract

Objective:

To evaluate the economic impact of intravenous iron (in the form of intravenous iron preparation of ferric carboxymaltose) in three different clinical settings of iron deficiency anemia: chemotherapy-induced anemia in breast cancer, chemotherapy-induced anemia in digestive cancer, and perioperative anemia in knee and hip surgery.

Methods:

The economic model compared the usual therapeutic strategies of anemia without intravenous iron and strategies including intravenous iron, in each of the three clinical settings selected. Costs related to anemia treatment by erythropoiesis-stimulating agents (ESA), blood transfusion, and intravenous iron were estimated and compared inside each setting. Cost savings were calculated from the French healthcare payer perspective. Data included in the economic model were obtained from scientific literature, public health agencies, and medical experts.

Results:

The most prominent annual cost savings were observed in chemotherapy-induced anemia in breast cancer (€997 and €360 per patient for metastatic and non-metastatic breast cancers, respectively; global cost saving, €33.6 million). This large impact of intravenous iron on costs was mainly explained by both a lower number of women treated and lower ESA dosing. Mean annual cost saving in digestive cancers and knee and hip surgery were estimated to €168 and €216 per patient and global cost savings of €7.5 and €12.1 million, respectively. Overall, annual cost savings in these three settings were estimated to €53 million including €39 million for ESA cost savings. Sensitivity analysis showed that strategies including intravenous iron remained cost-effective even with wide variations in the assumptions, particularly for cost savings on ESA.

Limitations:

Economic model based on literature data and expert opinions.

Conclusions:

The present economic model suggests that use of intravenous iron, according to recommendations of international guidelines, is cost saving, particularly in chemotherapy-induced anemia in breast cancers.     

Cost-effectiveness of insulin detemir compared with neutral protamine Hagedorn insulin in patients with type 1 diabetes using a basal-bolus regimen in five European countries

Abstract

Objectives: The aim of this analysis was to evaluate the long-term clinical and economic outcomes associated with insulin detemir and neutral protamine Hagedorn (NPH) insulin in combination with mealtime insulin aspart in patients with type 1 diabetes in Belgian, French, German, Italian and Spanish settings.

Methods: The published and validated IMS CORE Diabetes Model was used to make long-term projections of life expectancy, quality-adjusted life expectancy and direct medical costs. The analysis was based on patient characteristics and treatment effects from a 2-year randomised controlled trial. Events were projected for a time horizon of 50 years. Potential uncertainty using a modelling approach was addressed.

Results: Basal-bolus therapy with insulin detemir was projected to improve quality-adjusted life expectancy by 0.45 years versus NPH in the German setting, with similar improvements in the other countries. Insulin detemir was associated with cost savings in Belgium, Germany and Spain. In France and Italy, lifetime costs were slightly higher in the detemir arm, leading to incremental cost-effectiveness ratios of €519 per QALY gained and €3,256 per QALY gained, respectively.

Conclusions: Compared to NPH, insulin detemir is likely to be a dominant treatment strategy in Belgium, Germany and Spain and highly cost-effective in France and Italy in patients with type 1 diabetes.     

Inverse probability weighting to control for censoring in a post hoc analysis of quality-adjusted survival data from a clinical trial of temsirolimus for renal cell carcinoma

Abstract

Objectives: The Belgian third-party payer wishes to set reimbursement tariffs at a level that reflects the costs of orthotic braces. This article aims to calculate production and distribution costs of a prefabricated hard neck and knee brace and to explore whether Belgian tariffs and actual retail prices correspond with estimated costs of these two braces.

Methods: The cost model considered manufacturing costs, general overheads, research and development costs, warehousing costs, profit and distribution margins. Data were gathered from manufacturers, a production site visit, desk research, a decomposition of finished products and stakeholder interviews. The price year was 2007.

Results: The cost model estimated a retail price of €55–€150 for the neck brace, depending on assumptions. The estimated retail price for the neck brace was lower than the reimbursement tariff of €194 and the actual retail price of €241. The estimated retail price of €331–€694 for the knee brace was lower than the actual retail price of €948.

Conclusions: Actual retail prices and reimbursement tariffs for a neck brace and a knee brace exceeded prices based on estimated costs. Therefore, there appears to be scope for reducing tariffs.     

Cost-effectiveness analysis of bariatric surgery for morbid obesity in Belgium

Aims: This study presents the cost-effectiveness analysis of bariatric surgery in Belgium from a third-party payer perspective for a lifetime and 10-year horizon.

Materials and methods: A decision analytic model incorporating Markov process was developed to compare the cost-effectiveness of gastric bypass, sleeve gastrectomy, and adjustable gastric banding against conventional medical management (CMM). In the model, patients could undergo surgery, or experience post-surgery complications, type 2 diabetes, cardiovascular diseases, or die. Transition probabilities, costs, and utilities were derived from the literature. The impact of different surgical methods on body mass index (BMI) level in the base-case analysis was informed by the Scandinavian Obesity Surgery Registry and the Swedish Obese Subject (SOS) study. Healthcare resource use and costs were obtained from Belgian sources. A base-case analysis was performed for the population, the characteristics of which were obtained from surgery candidates in Belgium.

Results: In the base-case analysis over a 10-year time horizon, the increment in quality-adjusted life-years (QALYs) gained from bariatric surgery vs CMM was 1.4 per patient, whereas the incremental cost was €3,788, leading to an incremental cost-effectiveness ratio (ICER) of €2,809 per QALY. Over a lifetime, bariatric surgery produced savings of €9,332, an additional 1.1 life years and 5.0 QALYs. Bariatric surgery was cost-effective at 10 years post-surgery and dominant over conventional management over a lifetime horizon.

Limitations: The model did not include the whole scope of obesity-related complications, and also did not account for variation in surgery outcomes for different populations of diabetic patients. Also, the data about management of patients after surgery was based on assumptions and the opinion of a clinical expert.

Conclusions: It was demonstrated that a current mix of bariatric surgery methods was cost-effective at 10 years post-surgery and cost-saving over the lifetime of the Belgian patient cohort considered in this analysis.     

Solifenacin in the treatment of overactive bladder syndrome in Italian patients: pharmacoeconomic evaluation

Abstract

Objective: To investigate the pharmacoeconomic performance of treatment with solifenacin, a new antimuscarinic with selectivity for the bladder, when compared to tolterodine and placebo, in Italian patients with overactive bladder (OAB).

Methods: The evaluation was performed using a Markov model. The time horizon of the simulation was 52 weeks, with 1-week cycles. The model simulated outcomes and costs of the treatment with solifenacin (5 mg/day), tolterodine ER (4 mg/day) and no treatment in a cohort representative of the Italian population with OAB. The analysis was conducted mainly from the perspective of the patient, since drugs for the treatment of OAB are not included in the Italian reimbursement list. A supplementary scenario explored the consequences of a hypothetical reimbursement decision by the Italian Health Service to reimburse half of the current retail price in incontinent and responding OAB patients only.

Results: Both treatments produced a reduction in symptoms and improvement in patients' quality of life, with an cost increase of about €540–640/patient/year with solifenacin and €680–780/patient/year with tolterodine. In a cost/utility analysis, solifenacin dominated tolterodine as it resulted in both more effective and less costly treatment; the cost/utility ratio with respect to no treatment was in the range €7,600–18,600/Quality-adjusted life year. The overall expenditure of the hypothesised reimbursement decision was estimated to be about 23 million euros, with a cost/utility ratio of about €600–2,400/Quality-adjusted life year, indicating an efficient allocation of health resources.

Conclusions: While both tolterodine and solifenacin appear to be cost/effective in Italy, the latter has proven to be superior.

     

Comparative cost analysis of management of secondary hyperparathyroidism with paricalcitol or cinacalcet with low-dose vitamin D in hemodialysis patients

Abstract

Objective:

The objective of this analysis was to compare costs of paricalcitol or cinacalcet plus low dose vitamin D, and of phosphate binders, in patients in the IMPACT SHPT study; and to extrapolate those to estimate expected annual maintenance costs.

Methods:

IMPACT SHPT was a 28-week, randomized, open-label trial. Subjects from 12 countries received intravenous (IV) or oral paricalcitol, or oral cinacalcet plus fixed IV doxercalciferol or oral alfacalcidol. The primary end-point was the proportion of subjects who achieved a mean intact parathyroid hormone (iPTH) value of 150–300?pg/mL during weeks 21–28 (evaluation period). This study compares the costs of study drugs and phosphate binders among participants during the study and annualized. This analysis includes only those subjects that reached the evaluation period (134 in each group).

Results:

The mean total drug costs over the study period were €2606 (SD?=?€2000) in the paricalcitol group and €3034 (SD?=?€3006) in the cinacalcet group (difference €428, p?=?0.1712). The estimated annualized costs were €5387 (SD?=?€4139) in the paricalcitol group and €6870 (SD?=?€6256) in the cinacalcet group (difference €1492, p?=?0.0395). In addition, a significantly greater proportion (p?=?0.010) of subjects in the paricalcitol arm (56.0%) achieved an iPTH of 150–300?pg/mL during the evaluation period compared to the cinacalcet arm (38.2%).

Limitations:

This was a secondary analysis of the IMPACT SHPT study which was not designed or powered for costs as an outcome. The dosing of study drugs and phosphate binders in the IMPACT study may not reflect actual practice, and patients were followed for 28 weeks, while the treatment of SHPT is long-term.

Conclusion:

Patients with SHPT requiring hemodialysis who were treated with a paricalcitol-based regimen for iPTH control had lower estimated annual drug costs compared to those treated with cinacalcet plus low-dose vitamin D.     

Economic burden of thromboembolic and hemorrhagic complications in non-valvular atrial fibrillation in Algeria (the ELRAGFA study)

Abstract

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia, with substantial public health and economic impact on healthcare systems due to the prevention and management of thromboembolic and hemorrhagic complications. In Algeria, stroke is a leading cause of death, representing 15.6% of all deaths in 2012. Current data on the epidemiology and costs associated with non-valvular AF (NVAF) in Algeria are not available.

Methods: A three-step approach was undertaken to estimate the economic burden of NVAF in Algeria. First, a literature review identified the epidemiological burden of the disease. Second, expert clinicians practicing in Algerian hospitals were surveyed on consumed resources and unit costs of treatment and management of complications and prevention. Finally, these data were combined with event probabilities in an economic model to estimate the annual cost of NVAF prevention and complications for the Algerian healthcare system.

Results: Based on literature and demographics data, it was estimated that there are currently 187,686 subjects with NVAF in Algeria. Seventy per cent of this population was treated for prevention, half of which were controlled. Cost of prevention was estimated at 203 million DZD (€1.5 million) for drugs and 349 million DZD (€2.6 million) for examinations. Mean hospitalization costs for complications ranged between 123,500 and 435,500 DZD (€910–3,209), according to the type and severity of complications. Hospitalization costs for thromboembolic and hemorrhagic complications were estimated at 8,313 million DZD (€62 million), half of which was for untreated patients. Finally, the economic burden of NVAF was estimated at 8,865 million DZD (>€65 million) annually.

Conclusion: The economic burden of NVAF is important in Algeria, largely driven by untreated and INR-uncontrolled patients. There is a lack of information on the Algerian healthcare system that could increase uncertainty around this assessment, but it clearly establishes the importance of NVAF as a public health concern.     

A cost-effectiveness and budget impact analysis of apremilast in patients with psoriasis in the Italian setting

Abstract

Aims: The aim of this study was to conduct a cost-effectiveness analysis, as well as a budget impact analysis, on the use of apremilast for the treatment of adult patients with moderate-to-severe plaque psoriasis (defined as a psoriasis area severity index [PASI]?≥?10), who failed to respond to, had a contraindication to, or were intolerant to other systemic therapies, within the Italian National Health Service (NHS).

Materials and methods: A Markov state-transition cohort model adapted to the Italian context was used to compare the costs of the currently available treatments and of the patients’ quality of life with two alternative treatment sequences, with or without apremilast as pre-biologic therapy. Moreover, a budget impact model was developed based on the population of patients treated for psoriasis in Italy, who would be eligible for treatment with apremilast.

Results: Over 5?years, the cost-effectiveness analysis showed that the strategy of using apremilast before biologic therapy was dominant compared with the sequence of biologic treatments without apremilast. In addition, it is important to underline that the use of apremilast slightly increases the quality-adjusted life years gained over 5?years. Furthermore, within the budget impact analysis, the strategy including apremilast would lead to a saving of €16 million within 3?years. Savings would mainly be related to a reduction in pharmaceutical spending, hospital admissions and other drug administration-related costs.

Conclusion: These models proved to be robust to variation in parameters and it suggested that the use of apremilast would lead to savings to the Italian healthcare system with potential benefits in terms of patients’ quality of life.     

Annual cost of hospitalization,inpatient rehabilitation and sick leave of anal cancer in Germany

Abstract

Objective:

Literature on the economic burden of anal cancer in Germany is scarce. About 84% of these cancers are associated with human papillomavirus infection. This study, therefore, aimed to assess the annual costs of human papillomavirus-related anal cancer incurred by hospitalization, inpatient rehabilitation, and sick leave in 2008 in Germany.

Methods:

A cross-sectional retrospective analysis of five German databases covering hospital treatment, inpatient rehabilitation, and sick leave in 2008 was performed. All hospital, inpatient rehabilitation, and sick leave cases due to anal cancer in 2008 were analyzed. Associated numbers of anal cancer hospitalizations, healthcare resource use, and costs were identified and extracted using the ICD-10 code C21 as the main diagnosis. The annual cost of human papillomavirus-related anal cancer was estimated based on the percentage of anal cancer likely to be attributable to human papillomavirus.

Results:

In 2008, there were 5774 hospitalizations (39% males, 61% females), 517 inpatient rehabilitations, and 897 sick leaves due to anal cancer representing costs of €34.11 million. The estimated annual costs associated with human papillomavirus-related anal cancer were €28.72 million, mainly attributed to females (62%). Direct costs accounted for 90% (86% for hospital treatment, 4% for inpatient rehabilitation) and indirect costs due to sick leave accounted for 10% of human papillomavirus-related costs.

Conclusions:

The economic burden of human papillomavirus-related anal cancer in 2008 in Germany is under-estimated, since costs incurred by outpatient management, outpatient chemotherapy, long-term care, premature retirement, and premature death were not included. However, this study is the first analysis to investigate the economic burden of anal cancer in Germany. The estimated annual costs of human papillomavirus-related anal cancer contribute to a significant economic burden in Germany and should be considered when assessing health and economic benefits of human papillomavirus vaccination in both genders.     

Comparison of treatment costs in inadequately controlled type 2 diabetes in Germany based on the APOLLO trial with insulin glargine

Abstract

Objective: A cost analysis of once-daily insulin glargine versus three-times daily insulin lispro in combination with oral antidiabetic drugs (OADs) for insulin-naive type 2 diabetes patients in Germany based on the APOLLO trial (A Parallel design comparing an Oral antidiabetic drug combination therapy with either Lantus once daily or Lispro at mealtime in type 2 diabetes patients failing Oral treatment).

Methods: Annual direct treatment costs were estimated from the perspective of the German statutory health insurance (SHI). Costs accounted for included insulin medication, disposable pens and consumable items (needles, blood glucose test strips and lancets). Sensitivity analyses (on resource use and unit costs) were performed to reflect current German practice.

Results: Average treatment costs per patient per year in the base case were €1,073 for glargine and €1,794 for lispro. Insulin costs represented 65% vs. 37% of total costs respectively. Acquisition costs of glargine were offset by the lower costs of consumable items (€380 vs. €1,139). Sensitivity analyses confirmed the robustness of the results in favour of glargine. All scenarios yielded cost savings in total treatment costs ranging from €84 to €727.

Conclusions: Combination therapy of once-daily insulin glargine versus three-times daily insulin lispro both with OADs, in the management of insulin-dependent type 2 diabetes offers the potential for substantial cost savings from the German SHI perspective.     

Economic evaluation of anti-epileptic drug therapies with specific focus on teratogenic outcomes

Abstract

Background:

Anti-epileptic drugs are known to be teratogenic, yet many women do need to continue the anti-epileptic drug use during pregnancy.

Objectives:

To perform an economic evaluation of the anti-epileptic drug choice in young women who potentially wish to become pregnant. In particular, to estimate the impact of teratogenicity on the costs per quality adjusted life year (QALY).

Methods:

A decision-tree model is used to calculate the costs per QALY, taking into account the malformation risk in offspring due to the exposure to carbamazepine, lamotrigine or valproic acid, based on the European birth cohort of 2007. Probabilistic sensitivity analyses were performed using Monte Carlo simulation.

Results:

Valproic acid is dominated by carbamazepine after rank ordering on costs. The incremental cost-effectiveness of lamotrigine vs carbamazepine was estimated at €175,534 per QALY. Although valproic acid was dominated by carbamazepine in terms of costs and related effects, it is clinically relevant to compare lamotrigine with valproic acid. In particular, treatment options are dependent on several individual and clinical characteristics and these agents are therefore not always considered as interchangeable for all specified populations. The incremental cost-effectiveness for lamotrigine vs valproic acid was estimated at €13,370 per QALY. With assuming a willingness to pay threshold of €50,000 per QALY, results from the probabilistic analysis resulted in an acceptance level for lamotrigine vs carbamazepine and lamotrigine vs valproic acid of 4% and 99%, respectively.

Conclusion:

Based on epidemiological data it is advised to whenever possible avoid valproic acid during pregnancy. Both carbamazepine and lamotrigine are estimated to be cost-effective treatment options vs valproic acid if focused on teratogenicity.     

Budget impact analysis of everolimus for the treatment of hormone receptor positive,human epidermal growth factor receptor-2 negative (HER2−) advanced breast cancer in Kazakhstan

Abstract

Objective:

The aim of this study was to determine the budget impact of everolimus (in combination with letrozole/anastrozole) as a second-line treatment for ER+ HER2? negative advanced and metastatic breast cancer in post-menopausal women.

Research design and methods:

A cumulative cohort model was developed to estimate the 5-year costs associated with introducing everolimus to the Kazakh healthcare system. Two alternative market share scenarios were compared: with everolimus and without everolimus. PFS and OS data were taken from the trial and extrapolated. The background costs of the pre-progressed and post-progressed health states, drug costs and costs associated with adverse events were included in the model.

Results:

The 5-year results from the budget impact analysis demonstrate that the introduction of everolimus leads to a 12% increase in drug costs, a 2% reduction in pre-progression health state costs, a 1% increase in post-progression health state costs, and a 2% reduction in adverse event costs. The net result is only a modest increase in total costs; a 2.69% increase of T201 million, from T7.5 billion to T7.7 billion over a period of 5 years.

Conclusions:

The analysis estimated that, if everolimus were to be introduced to the Kazakh healthcare market for the treatment of ER+ HER2? advanced breast cancer, there would be minimal impact upon overall healthcare expenditure. An increase in drug acquisitions costs was almost exactly offset by a reduction in other healthcare costs, due to improved management of the disease.
