Costs of administration,travelling, and productivity losses associated with hospital administration of multiple myeloma drugs in Finland

Aim: To estimate the drug administration, travelling, and productivity costs associated with infusion or subcutaneous proteasome inhibitor (PI) treatments (specifically carfilzomib and bortezomib) for multiple myeloma (MM) patients in Finland.

Materials and methods: Price tariffs of Finnish hospital districts are used as the basis of invoicing sent to healthcare service payers. A review of these price tariff lists was conducted and obtained data analysed to estimate the mean unit cost of PI administration visit. Travelling costs stratified by areas with different population densities were assessed, based on the national travelling reimbursement register data maintained by the Social Insurance Institution of Finland. Productivity costs due to time spent on administration visits and travelling were estimated based on an expert interview and a spatial healthcare accessibility analysis.

Results: Nineteen (95%) of the Finnish hospital districts were included in the review. Relevant unit cost information was found for 15 (75%) of the districts. The mean PI administration cost alone was 270€ (95% CI?=?189€–351€) per administration and increased to 371€ when travelling costs were included. Productivity costs added, the mean PI administration costs totalled 405€ for bortezomib and 437€ for carfilzomib.

Limitations: The costing rationale of price tariffs may vary between hospital districts. Productivity costs were estimated conservatively, due to lack of data.

Conclusions: The administration of intravenous or subcutaneous PIs to treat MM in healthcare facilities causes significant and potentially avoidable healthcare, travelling, and indirect costs, and they should be included in all health economic evaluations (HEEs). As the cost estimates utilized in this study represent most of central hospitals in the country, they provide useful information for future HEEs. A broader conclusion is that novel oral medications, such as the first oral PI, have a significant potential for reducing administration-related costs of subcutaneous or intravenous PIs.     

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.

     

Cost estimation of patients admitted to the intensive care unit: a case study of the Teaching University Hospital of Thessaly

Objective: This study aimed to estimate the cost of patients admitted to the Intensive Care Unit (ICU) of the Teaching University Hospital of Thessaly (TUHT) in 2006 and to demonstrate discrepancies between actual hospitalisation cost and social funds’ reimbursement.

Methods: Cost analysis was performed using a macro-costing approach, which focused on the estimation of nominal and actual cost per ICU patient. Data were derived from the annual records of resources consumed in each hospital unit and from hospital balance sheets. Sensitivity analysis was also performed by inflating nominal costs to present values.

Results: There were 312 patients admitted to the ICU. Mean actual cost per ICU patient was estimated at €16,516, whereas actual reimbursement from social funds was only €1,671. This means that reimbursement accounted for just 10% of the actual hospitalisation cost. Once nominal costs were inflated to present values, the reimbursement accounted for 25% of the actual hospitalisation cost. The major cost drivers of ICU hospitalisation were personnel costs followed by infrastructure, hotel services and pharmaceutical expenditure. These results may be limited by a lack of consideration for clinical outcomes along with a high level of aggregation in cost data.

Conclusion: Reimbursement should be re-adjusted in order to balance public hospital deficits and make public-private mix viable. This way, intensive care capacity would increase and allow a more equitable distribution of healthcare resources.     

A cost-effectiveness modeling evaluation comparing a biosimilar follitropin alfa preparation with its reference product for live birth outcome in Germany,Italy and Spain

Abstract

Background/objective: Although biosimilar drugs may be cheaper to purchase than reference biological products, they may not be the most cost-effective treatment to achieve a desired outcome. The analysis reported here compared the overall costs to achieve live birth using the reference follitropin alfa (GONAL-f) or a biosimilar (Ovaleap) in Spain, Italy and Germany.

Methods: Patient and treatment data was obtained from published sources; assisted-reproductive technology, gonadotropin, follow-up and adverse-event-related costs were calculated from tariffs and reimbursement frameworks for each country. Incremental cost-effectiveness ratios (ICERs) were calculated from the difference in costs between reference and biosimilar in each country, divided by the difference in live-birth rates. Mean cost per live birth was calculated as total costs divided by the live-birth rate.

Results: The published live birth rates were 32.2% (reference) and 26.8% (biosimilar). Drug costs per patient were higher for the reference recombinant human follicle-stimulating hormone in all three countries, with larger cost differences in Germany (€157.38) and Italy (€141.50) than in Spain (€22.41). The ICER for the reference product compared with the biosimilar was €2917.47 in Germany, €415.43 in Spain and €2623.09 in Italy. However, the overall cost per live birth was higher for the biosimilar in all three countries (Germany €8135.04 vs. €9185.34; Italy €8545.22 vs. €9733.37; Spain €14,859.53 vs. €17,767.19). Uncertainty in efficacy, mean gonadotropin dose and costs did not have a strong effect on the ICERs.

Conclusions: When considering live birth outcomes, treatment with the reference follitropin alfa was more cost effective than treatment with the biosimilar follitropin alfa.     

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.     

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.     

Cost effectiveness of zoledronic acid in the management of skeletal metastases in hormone-refractory prostate cancer patients in France,Germany, Portugal,and the Netherlands

Abstract

Objective:

Zoledronic acid (ZOL) reduces the risk of skeletal related events (SREs) in hormone-refractory prostate cancer (HRPC) patients with bone metastases. This study assessed the cost effectiveness of ZOL for SRE management in French, German, Portuguese, and Dutch HRPC patients.

Methods:

This analysis was based on the results of a randomized phase III clinical trial wherein HRPC patients received up to 15 months of ZOL (n?=?214) or placebo (n?=?208). Clinical inputs were obtained from the trial. Costs were estimated using hospital tariffs, published, and internet sources. Quality adjusted life-years (QALYs) gained were estimated from a separate analysis of EQ-5D scores reported in the trial. Uncertainty surrounding outcomes was addressed via univariate sensitivity analyses.

Results:

ZOL patients experienced an estimated 0.759 fewer SREs and gained an estimated 0.03566 QALYs versus placebo patients. ZOL was associated with reduced SRE-related costs [net costs] (?€2396 [€1284] in France, ?€2606 [€841] in Germany, ?€3326 [€309] in Portugal and ?€3617 [€87] in the Netherlands). Costs per QALY ranged from €2430 (Netherlands) to €36,007 (France).

Conclusions:

This analysis is subject to the limitations of most cost-effectiveness analyses: it combines data from multiple sources. Nevertheless, the results strongly suggest that ZOL is cost effective versus placebo in French, German, Portuguese, and Dutch HRPC patients.     

Cost minimisation analysis of 12 or 24 weeks of peginterferon alfa-2b + ribavirin for hepatitis C virus

Abstract

Background: Pegylated interferon and ribavirin are at present the standard treatment for chronic hepatitis C virus (HCV) patients.

Objective: The present economic evaluation compared 12 vs. 24 weeks of peginterferon alfa-2b + ribavirin treatments for HCV genotypes 2 or 3. Shortening the period of antiviral therapy is important in terms of adverse events and costs.

Methods: Clinical evidence was based on the results of a multicentre, randomised controlled clinical trial (RCCT) conducted in Italy, which found that the shorter course of therapy was as effective as the 24-week course for patients with HCV genotypes 2 or 3 responding to treatment at 4 weeks. A cost minimisation analysis was performed. The analysis took the Italian National Health Service (INHS) point of view, thus only healthcare costs (drugs, medical consultations, diagnostic tests, hospital admissions) were considered. Healthcare activities were estimated by the RCCT principal investigators and were priced by applying the INHS tariffs and prices.

Results: The total mean cost per patient was estimated at €9,785 for the standard group and €7,508 for the variable-duration group. Sensitivity analysis confirmed the robustness of the baseline results.

Conclusions: This study showed that the variable-duration regimen can be recommended as an efficient use of resources for patients from the INHS perspective.     

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.     

Cost effectiveness of posaconazole in the prophylaxis of invasive fungal infections in acute leukaemia patients for the French healthcare system

Abstract

Background:

Acute myeloblastic leukaemia (AML) patients are at high risk of suffering from invasive fungal infections (IFI). Posaconazole demonstrated higher efficacy than standard azole agents (SAA) in the prophylaxis of IFI in this population.

The authors estimated the cost effectiveness of posaconazole versus SAA in France.

Methods:

A decision-tree model was developed to compare posaconazole with SAA with the results of a published clinical trial. Clinical events were modelled with chance nodes reflecting probabilities of IFI, IFI-related death, and death from other causes. Medical resource consumption and costs were obtained from results of the clinical trial and from a dedicated survey on the costs of treating IFI using a retrospective chart review design.

Results:

IFI treatment costs were estimated using medical files from 50 AML patients from six French centres, with a proven and probable IFI, who had been followed-up for 298 days on average. Direct costs directly related to IFI were estimated at €51,033, including extra costs of index hospitalisation, costs of antifungal therapy and additional hospitalisations related to IFI treatment. The model indicated that the healthcare costs for the posaconazole strategy were €5,223 (€2,697 for prophylaxis and €2,526 for IFI management), which was €859 less than the €6,083 in costs with SAA (€469 for prophylaxis and €5614 for IFI management). A sensitivity analysis indicated that there was an 80% probability that prophylaxis using the posaconazole strategy would be superior.

Conclusion:

The findings from this analysis suggest that posaconazole use is a clinically and economically dominant strategy in the prophylaxis of IFI in AML patients, given the usual limits of economic models and the uncertainty of costs estimates.     

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.     

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.     

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.     

Impact of DRG billing system on health budget consumption in percutaneous treatment of mitral valve regurgitation in heart failure

Abstract

Objective:

Percutaneous correction of mitral regurgitation (MR) by MitraClip (Abbot Vascular, Abbot Park, Illinois, USA) trans-catheter procedure (MTP) may represent a treatment for an unmet need in heart failure (HF), but with a largely unclear economic impact.

Research design and methods:

This study estimated the economic impact of the MTP in common practice using the disease-related group (DRG) billing system, duration and average cost per day of hospitalization as main drivers. Life expectancy was estimated based on the Seattle Heart Failure Model. Quality-of-life was derived by standard questionnaires to compute quality-adjusted year-life costs.

Results:

Over 5535 discharges between 2012–2013, HF as DRG 127 was the main diagnosis in 20%, yielding a reimbursement of €3052.00/case; among the DRG 127, MR by ICD-9 coding was found in 12%. Duration of hospitalization was longer for DRG 127 with than without MR (9 vs 8 days, p?<?0.05). HF in-hospital management generated most frequently deficit, in particular in the presence of MR, due to the high costs of hospitalization, higher than reimbursement. MTP to treat MR allowed DRG 104-related reimbursement of €24,675.00. In a cohort of 34 HF patients treated for MR by MTP, the global budget consumption was 2-fold higher compared to that simulated for those cases medically managed at 2-year follow-up. Extrapolated cost per quality-adjusted-life-years (QALY) for MTP at year-2 follow-up was ～€16,300.

Conclusions:

Based on DRG and hospitalization costing estimates, MTP might be cost-effective in selected HF patients with MR suitable for such a specific treatment, granted that those patients have a clinical profile predicting high likelihood of post-procedural clinical stability in sufficiently long follow-up.     

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.     

Ostomy appliance prices in Europe

Abstract

Objective: This article aims to compare market prices (i.e., third-party reimbursement and patient co-payment) of one-piece and two-piece colostomy, ileostomy and ureterostomy appliances in Belgium, Denmark, England and the Netherlands in 2005.

Methods: Data were collected through contacts with health authorities, health insurance companies, manufacturers, industry associations and distributors. The price difference between Belgium and another country was expressed as a proportion of the Belgian price.

Results: A total of 64 out of the 72 ostomy appliance products considered were cheaper in Belgium. Prices of one-piece colostomy appliances and two-piece ileostomy appliances were consistently lower in Belgium. The highest prices of ostomy appliances were observed in the Netherlands. Sixteen out of 20 products and 21 out of 25 products were more expensive in Denmark and England, respectively, than in Belgium. Colostomy appliances were more expensive in England than in Belgium.

Conclusions: Market prices varied substantially between countries, indicating that manufacturers adapt their pricing strategy to the policy environment existing in the ostomy appliance market of each country. Also, there appears to be scope for reducing prices in some countries.     

Cost-effectiveness analysis of atypical long-acting antipsychotics for treating chronic schizophrenia in Finland

Abstract

Objective:

In Finland, regional rates of schizophrenia exceed those in most countries, impacting the healthcare burden. This study determined the cost-effectiveness of long-acting antipsychotic (LAI) drugs paliperidone palmitate (PP-LAI), olanzapine pamoate (OLZ-LAI), and risperidone (RIS-LAI) for chronic schizophrenia.

Method:

This study adapted a decision tree analysis from Norway for the Finnish National Health Service. Country-specific data were sought from the literature and public documents, guided by clinical experts. Costs of health services and products were retrieved from literature sources and current price lists. This simulation study estimated average 1-year costs for treating patients with each LAI, average remission days, rates of hospitalization and emergency room visits and quality-adjusted life-years (QALY).

Results:

PP-LAI was dominant. Its estimated annual average cost was €10,380/patient and was associated with 0.817 QALY; OLZ-LAI cost €12,145 with 0.810 QALY; RIS-LAI cost €12,074 with 0.809 QALY. PP-LAI had the lowest rates of hospitalization, emergency room visits, and relapse days. This analysis was robust against most variations in input values except adherence rates. PP-LAI was dominant over OLZ-LAI and RIS-LAI in 77.8% and 85.9% of simulations, respectively. Limitations include the 1-year time horizon (as opposed to lifetime costs), omission of the costs of adverse events, and the assumption of universal accessibility.

Conclusion:

In Finland, PP-LAI dominated the other LAIs as it was associated with a lower cost and better clinical outcomes.     

Economic and clinical comparison of atypical depot antipsychotic drugs for treatment of chronic schizophrenia in the Czech Republic

Abstract

Purpose:

The Czech Republic is faced with making choices between pharmaceutical products, including depot injectable antipsychotics. A pharmacoeconomic analysis was conducted to determine the cost-effectiveness of atypical depots.

Methods:

An existing 1-year decision-analytic framework was adapted to model drug use in this healthcare system. The average direct costs to the General Insurance Company of the Czech Republic of using paliperidone palmitate (Xeplion®), risperidone (Risperdal Consta®), and olanzapine pamoate (Zypadhera®) were determined. Literature-derived clinical rates populated the model, with costs adjusted to 2012 Euros using the consumer price index. Outcomes included quality-adjusted life-years (QALYs), days in remission, and proportions hospitalized or visiting emergency rooms. One-way sensitivity analyses were calculated for all important inputs. A multivariate probability analysis was used to examine the stability of results using 10,000 iterations of simulated input over reasonable ranges of all included variables.

Results:

Expected average costs/per patient treated were €5377 for PP-LAI, €6118 for RIS-LAI, and €6537 for OLZ-LAI. Respective QALYs were 0.817, 0.809, and 0.811; ER visits were 0.127, 0.134, and 0.141; hospitalizations were 0.252, 0.298, and 0.289. Results were generally robust in sensitivity analyses. PP-LAI dominated RIS-LAI and OLZ-LAI in 90.2% and 92.1% of simulations, respectively. Results were insensitive to drug prices but sensitive to adherence and hospitalization rates.

Conclusions:

PP-LAI dominated the other two drugs, as it had a lower overall cost and superior clinical outcomes, making it the preferred choice. Using PP-LAI in place of RIS-LAI for chronic relapsing schizophrenia would reduce the overall costs of care for the healthcare system.     

Cost effectiveness analysis of immunotherapy in patients with grass pollen allergic rhinoconjunctivitis in Germany

Abstract

Objectives:

An economic evaluation was conducted to assess the outcomes and costs as well as cost-effectiveness of the following grass-pollen immunotherapies: OA (Oralair; Stallergenes S.A., Antony, France) vs GRZ (Grazax; ALK-Abelló, Hørsholm, Denmark), and ALD (Alk Depot SQ; ALK-Abelló) (immunotherapy agents alongside symptomatic medication) and symptomatic treatment alone for grass pollen allergic rhinoconjunctivitis.

Methods:

The costs and outcomes of 3-year treatment were assessed for a period of 9 years using a Markov model. Treatment efficacy was estimated using an indirect comparison of available clinical trials with placebo as a common comparator. Estimates for immunotherapy discontinuation, occurrence of asthma, health state utilities, drug costs, resource use, and healthcare costs were derived from published sources. The analysis was conducted from the insurant’s perspective including public and private health insurance payments and co-payments by insurants. Outcomes were reported as quality-adjusted life years (QALYs) and symptom-free days. The uncertainty around incremental model results was tested by means of extensive deterministic univariate and probabilistic multivariate sensitivity analyses.

Results:

In the base case analysis the model predicted a cost-utility ratio of OA vs symptomatic treatment of €14,728 per QALY; incremental costs were €1356 (95%CI: €1230; €1484) and incremental QALYs 0.092 (95%CI: 0.052; 0.140). OA was the dominant strategy compared to GRZ and ALD, with estimated incremental costs of ?€1142 (95%CI: ?€1255; ?€1038) and ?€54 (95%CI: ?€188; €85) and incremental QALYs of 0.015 (95%CI: ?0.025; 0.056) and 0.027 (95%CI: ?0.022; 0.075), respectively. At a willingness-to-pay threshold of €20,000, the probability of OA being the most cost-effective treatment was predicted to be 79%. Univariate sensitivity analyses show that incremental outcomes were moderately sensitive to changes in efficacy estimates. The main study limitation was the requirement of an indirect comparison involving several steps to assess relative treatment effects.

Conclusion:

The analysis suggests OA to be cost-effective compared to GRZ and ALD, and a symptomatic treatment. Sensitivity analyses showed that uncertainty surrounding treatment efficacy estimates affected the model outcomes.     

Cost-minimization analysis of alemtuzumab compared to fingolimod and natalizumab for the treatment of active relapsing-remitting multiple sclerosis in the Netherlands

Aim: In active relapsing remitting multiple sclerosis (RRMS) patients requiring second-line treatment, the Dutch National Health Care Institute (ZiN) has not stated a preference for either alemtuzumab, fingolimod, or natalizumab. The aim was to give healthcare decision-makers insight into the differences in cost accumulation over time between alemtuzumab—with a unique, non-continuous treatment schedule—and fingolimod and natalizumab for second-line treatment of active RRMS patients in the Netherlands.

Methods: In line with ZiN’s assessment, a cost-minimization analysis was performed from a Dutch healthcare perspective over a 5-year time horizon. Resource use was derived from hospital protocols and summaries of product characteristics, and validated by two MS specialists. Unit costs were based on national tariffs and guidelines. Robustness of the base case results was verified with multiple sensitivity and scenario analyses.

Results: Alemtuzumab results in cost savings compared to fingolimod and natalizumab from, respectively, 3.3 and 2.8 years since treatment initiation onwards. At 5 years, total discounted costs per patient of alemtuzumab were €79,717, followed by fingolimod with €110,044 and natalizumab with €122,238, resulting in cost savings of €30,327 and €42,522 for alemtuzumab compared to fingolimod and natalizumab, respectively. Key drivers of the model are drug acquisition costs and the proportions of patients that do not require further alemtuzumab treatment after either two, three, or four courses.

Limitations: No treatment discontinuation and associated switching between treatments were incorporated. Consequences of JC virus seropositivity while continuing natalizumab treatment (e.g. additional monitoring) were omitted from the base case.

Conclusion: The current cost-minimization analysis demonstrates that, from the Dutch healthcare perspective, treating active RRMS patients with alemtuzumab results in cost savings compared to second-line alternatives fingolimod and natalizumab from ～3 years since treatment initiation onwards. After 5 years, alemtuzumab’s cost savings are estimated at €30k compared to fingolimod and €43k compared to natalizumab.
