The Economic Potential of Smoking Cessation Interventions at the Point of Diagnosis of Non-Small Cell Lung Cancer.

OBJECTIVES: Stopping smoking has proven benefits in nearly all illnesses but the impact and health economic benefits of stopping smoking after a diagnosis of lung cancer are less well defined. We assessed the cost-effectiveness of smoking cessation (SC) services for patients with newly diagnosed lung cancer against current usual care, where patients are unlikely to receive SC service referral. METHODS: A health economic model was constructed in Excel. The modelled population comprised of patients with a new diagnosis of non-small cell lung cancer (NSCLC). Data from the LungCast data set (Clinical Trials Identifier NCT01192256) were used to estimate model inputs. A structured search of published literature identified inputs not represented in LungCast, including healthcare resource use and costs. Costs were estimated from a 2020/2021 UK National Health Service and Personal Social Services perspective. The model estimated the incremental quality-adjusted life-year (QALY) gained in patients with newly diagnosed NSCLC receiving targeted SC intervention than those receiving no intervention. Extensive one-way sensitivity analyses explored input and data set uncertainty. RESULTS: In the 5-year base case, the model estimated an incremental cost of £14 904 per QALY gained through SC intervention. Sensitivity analysis estimated an outcome range of between £9935 and £32 246 per QALY gained. The model was most sensitive to the estimates of relative quit rates and expected healthcare resource use. CONCLUSION: This exploratory analysis indicates that SC intervention for smokers with patients with newly diagnosed NSCLC should be a cost-effective use of UK National Health Service resources. Additional research with focused costing is needed to confirm this positioning.

The cost of inpatient burn management in Nepal.

INTRODUCTION: The management of burns is costly and complex with inpatient burns accounting for a high proportion of the costs associated with burn care. We conducted a study to estimate the cost of inpatient burn management in Nepal. Our objectives were to identify the resource and cost components of the inpatient burn care pathways and to estimate direct and overhead costs in two specialist burn units in tertiary hospitals in Nepal. METHODS: We conducted fieldwork at two tertiary hospitals to identify the cost of burns management in a specialist setting. Data were collected through semi-structured in-depth interviews (IDIs) and focus group discussions (FGDs) with burn experts; unit cost data was collected from hospital finance departments, laboratories and pharmacies. The study focused on acute inpatient burn cases admitted to specialist burn centres within a hospital-setting. RESULTS: Experts divided inpatient burn care pathways into three categories: superficial partial-thickness burns (SPT), mixed depth partial-thickness burns (MDPT) and full thickness burns (FT). These pathways were confirmed in the FGDs. A 'typical' burns patient was identified for each pathway. Total resource use and total direct costs along with overhead costs were estimated for acute inpatient burn patients. The average per patient pathway costs were estimated at NRs 102,194 (US$ 896.4), NRs 196,666 (US$ 1725), NRs 481,951 (US$ 4,227.6) for SPT, MDPT and FT patients respectively. The largest cost contributors were surgery, dressings and bed charges respectively. CONCLUSION: This study is a first step towards a comprehensive estimate of the costs of severe burns in Nepal.

A Structured Review to Assess the Current Status of Cost-Based Burns Research in Nepal.

The management of burns is costly and complex. The problem is compounded in low and middle income countries (LMICs) where the incidence of burn injuries is high but infrastructure and funding for management and prevention is limited. Cost of illness studies allows for quantification of the costs associated with public health problems. Without cost quantification, focus and allocation of funding is challenging. The authors explored the availability of cost-focused burns research data in a target LMIC. The focus of their research was Nepal. A structured literature review including published papers, Ministry of Health (MOH) and World Health Organization (WHO) statistics was conducted to identify cost of illness studies or evidence relating to burn-related resource and costs. Gaps in the evidence base were highlighted. Research methodologies from other LMICs were reviewed. We found 32 papers related to burn injury in Nepal, one key MOH document and one relevant WHO data source. Most research focused on the epidemiology and etiology of burns in Nepal. Of the papers, only 14 reported any type of burn-related resource use and only 1 paper directly reported (limited) cost data. No studies attempted an overall quantification of the cost of burns. MOH statistics provided no additional insight into costs. Our study found an almost complete lack of cost-focused burns research in Nepal. Primary research is needed to quantify the cost of burns in Nepal. Initial focus could usefully be on the cost of care in tertiary hospitals. A full cost of burns for Nepal remains some way off.

The Cost-effectiveness of Dulaglutide 1.5mg versus Exenatide QW for the Treatment of Patients with Type 2 Diabetes Mellitus in France.

INTRODUCTION: Dulaglutide is a novel onceweekly administered glucagon-like peptide 1 receptor agonist (GLP-1 RA) for the management of type 2 diabetes mellitus (T2DM). The objective of this analysis was to estimate the cost-effectiveness of dulaglutide 1.5 mg versus exenatide QW for the management of T2DM in France. METHODS: The QuintilesIMS CORE Diabetes Model was used to estimate the expected lifetime direct medical costs and outcomes of T2DM from the perspective of the French National Health Service. In the absence of head-to-head data, relative efficacy was derived from a network meta-analysis. Patient cohort characteristics were derived from the AWARD-2 trial. All patients were assumed to remain on treatment for 2 years before escalating to insulin therapy. Costs included treatment costs and costs associated with long-term complications of T2DM. Utilities were estimated based on a recent systematic review. One-way sensitivity analyses (OWSA) and probabilistic sensitivity analysis (PSA) were conducted. Cost-effectiveness acceptability curves (CEACs) were generated. RESULTS: Dulaglutide 1.5 mg was associated with lower costs (lifetime costs €41,562 vs €43,021) and increased health benefits (lifetime quality-adjusted life years: QALYs 9.804 vs 9.757) versus exenatide QW for the treatment of T2DM in France. OWSA and PSA indicated that results were robust across a range of plausible input parameters. The CEAC indicated a 99.5% probability that dulaglutide would be considered cost-effective at a willingness to pay of €30,000. CONCLUSION: Dulaglutide 1.5 mg reduced expected costs and increased expected QALYs when compared against exenatide QW for the treatment of T2DM in France. Compared with exenatide QW, dulaglutide 1.5 mg can provide additional health benefits for patients with T2DM and may result in cost savings for payers. FUNDING: Eli Lilly.

The cost-effectiveness of levodopa/carbidopa intestinal gel compared to standard care in advanced Parkinson's disease.

BACKGROUND: Parkinson's disease (PD) is an incurable, progressive neurological condition, with symptoms impacting movement, walking, and posture that eventually become severely disabling. Advanced PD (aPD) has a significant impact on quality-of-life (QoL) for patients and their caregivers/families. Levodopa/carbidopa intestinal gel (LCIG) is indicated for the treatment of advanced levodopa-responsive PD with severe motor fluctuations and hyper-/dyskinesia when available combinations of therapy have not given satisfactory results. AIMS: To determine the cost-effectiveness of LCIG vs standard of care (SoC) for the treatment of aPD patients. METHODS: A Markov model was used to evaluate LCIG vs SoC in a hypothetical cohort of 100 aPD patients with severe motor fluctuations from an Irish healthcare perspective. Model health states were defined by Hoehn & Yahr (H&Y) scale-combined with amount of time in OFF-time-and death. SoC comprised of standard oral therapy ± subcutaneous apomorphine infusion and standard follow-up visits. Clinical efficacy, utilities, and transition probabilities were derived from published studies. Resource use was estimated from individual patient-level data from Adelphi 2012 UK dataset, using Irish costs, where possible. Time horizon was 20 years. Costs and outcomes were discounted at 4%. Both one-way and probabilistic sensitivity analyses were conducted. RESULTS: The incremental cost-effectiveness ratio for LCIG vs SOC was €26,944/quality adjusted life year (QALY) (total costs and QALYs for LCIG vs SoC: €537,687 vs €514,037 and 4.37 vs 3.49, respectively). LCIG is cost-effective at a payer threshold of €45,000. The model was most sensitive to health state costs. CONCLUSION: LCIG is a cost-effective treatment option compared with SoC in patients with aPD.

The cost-effectiveness of 5-FU-SA in the treatment of actinic keratoses of the face and scalp in the UK secondary care setting.

OBJECTIVE: The objective of this analysis was to estimate the relative cost-effectiveness of Actikerall 1 (5-FU-SA) vs cryotherapy in a secondary care setting in the UK, for lesion-directed treatment in patients with actinic keratoses (AK) of the face and scalp. METHODS: The model was a simple decision tree, with a 6-month time horizon. The perspective was that of the UK National Health Service (NHS). Modeled treatment effects included reported per-patient histological clearance and recurrence rates. Cost inputs comprised professional consultation time and cost of medication. Health-related utility estimation followed previously published methodology. Adverse events were not modeled. The key data and model structural assumptions followed expected UK practice. One-way and probabilistic sensitivity analyses were conducted to assess structural and parameter uncertainty. RESULTS: 5-FU-SA was found to be less costly (-£204) and more effective (+0.001 QALY) in base case and sensitivity analyses. In the probabilistic analysis there was 100% probability of being cost-effective over cryotherapy at £20,000 willingness to pay. Cost of professional time was a key driver of the model outcome. 5-FU-SA remained dominant across a range of scenario analyses, including exploration of assumptions around setting of care. LIMITATIONS: The time horizon of the analysis was short and data were not extrapolated beyond the duration of the clinical trial; however, this approach is consistent with likely follow-up of an AK patient. The clinical outcomes observed in the trial were based on a large proportion of cryotherapy patients undergoing an additional cycle of treatment; this may not occur or be required in an experienced secondary care setting. CONCLUSION: 5-FU-SA could be considered as a cost-effective choice for treatment of AK lesions of the face and scalp in secondary and mixed care settings in the UK. Use of 5-FU-SA in patients who would otherwise be managed with cryotherapy has the potential to result in cost savings.

The cost-effectiveness of dulaglutide versus liraglutide for the treatment of type 2 diabetes mellitus in Spain in patients with BMI ≥30 kg/m2.

OBJECTIVE: Dulaglutide 1.5 mg once weekly is a novel glucagon-like peptide 1 (GLP-1) receptor agonist, for the treatment of type two diabetes mellitus (T2DM). The objective was to estimate the cost-effectiveness of dulaglutide once weekly vs liraglutide 1.8 mg once daily for the treatment of T2DM in Spain in patients with a BMI ≥30 kg/m2. METHODS: The IMS CORE Diabetes Model (CDM) was used to estimate costs and outcomes from the perspective of Spanish National Health System, capturing relevant direct medical costs over a lifetime time horizon. Comparative safety and efficacy data were derived from direct comparison of dulaglutide 1.5 mg vs liraglutide 1.8 mg from the AWARD-6 trial in patients with a body mass index (BMI) ≥30 kg/m2. All patients were assumed to remain on treatment for 2 years before switching treatment to basal insulin at a daily dose of 40 IU. One-way sensitivity analyses (OWSA) and probabilistic sensitivity analyses (PSA) were conducted to explore the sensitivity of the model to plausible variations in key parameters and uncertainty of model inputs. RESULTS: Under base case assumptions, dulaglutide 1.5 mg was less costly and more effective vs liraglutide 1.8 mg (total lifetime costs €108,489 vs €109,653; total QALYS 10.281 vs 10.259). OWSA demonstrated that dulaglutide 1.5 mg remained dominant given plausible variations in key input parameters. Results of the PSA were consistent with base case results. LIMITATIONS: Primary limitations of the analysis are common to other cost-effectiveness analyses of chronic diseases like T2DM and include the extrapolation of short-term clinical data to the lifetime time horizon and uncertainty around optimum treatment durations. CONCLUSION: The model found that dulaglutide 1.5 mg was more effective and less costly than liraglutide 1.8 mg for the treatment of T2DM in Spain. Findings were robust to plausible variations in inputs. Based on these results, dulaglutide may result in cost savings to the Spanish National Health System.

The Cost of Unintended Pregnancies in Canada: Estimating Direct Cost, Role of Imperfect Adherence, and the Potential Impact of Increased Use of Long-Acting Reversible Contraceptives.

OBJECTIVE: Unintended pregnancies (UPs) are associated with a significant cost burden, but the full cost burden in Canada is not known. The objectives of this study were to quantify the direct cost of UPs in Canada, the proportion of cost attributable to UPs and imperfect contraceptive adherence and the potential cost savings with increased uptake of long-acting reversible contraceptives (LARCs). METHODS: A cost model was constructed to estimate the annual number and direct costs of UP in women aged 18 to 44 years. Adherence-associated UP rates were estimated using perfect- and typical-use contraceptive failure rates. Change in annual number of UPs and impact on cost burden were projected in three scenarios of increased LARC usage. One-way sensitivity analyses were conducted to assess the impact of key variables on scenarios of increased LARC use. RESULTS: There are more than 180 700 UPs annually in Canada. The associated direct cost was over $320 million. Fifty-eight percent (58%) of UPs occurred in women aged 20 to 29 years at an annual cost of $175 million; 82% of this cost ($143 million) was attributable to contraceptive non-adherence. Increased LARC uptake produced cost savings of over $34 million in all three switching scenarios; the largest savings ($35 million) occurred when 10% of oral contraceptive users switched to LARCs. The minimum duration of LARC usage required before cost savings was realized was 12 months. CONCLUSION: The cost of UPs in Canada is significant and much of it can be attributed to imperfect contraceptive adherence. Increased LARC uptake may reduce contraceptive non-adherence, thereby reducing rates of UP and generating significant cost savings, particularly in women aged 20 to 29.

Objectif : Les grossesses non planifiées (GNP) sont associées à un fardeau financier considérable; au Canada, l'ampleur de ce fardeau demeure inconnue. Cette étude avait pour objectif de quantifier les coûts directs des GNP au Canada, la proportion des coûts liés aux GNP attribuables à une observance imparfaite du schéma posologique contraceptif et les économies potentielles associées à un accroissement de l'utilisation de modes de contraception réversible à action prolongée (CRAP). Méthodes : Un modèle de coût a été conçu pour estimer le nombre annuel de GNP et leurs coûts directs chez les femmes âgées de 18 à 44 ans. Les taux de GNP associés à l'observance ont été estimés au moyen des taux d'échec de la contraception en utilisation parfaite et en utilisation typique. Les modifications du nombre annuel de GNP et les effets sur le fardeau financier ont été projetés dans le cadre de trois scénarios prévoyant un accroissement du recours aux modes de CRAP. Des analyses simples de la variance en matière de sensibilité ont été menées pour évaluer les effets de variables clés sur les scénarios prévoyant un accroissement du recours aux modes de CRAP. Résultats : On compte plus de 180 700 GNP chaque année au Canada. Les coûts directs qui leur sont associés sont de plus de 320 millions de dollars. Cinquante-huit pour cent (58 %) des GNP se sont manifestées chez des femmes de 20 à 29 ans, ce qui représente un coût annuel de 175 millions de dollars; 82 % de ce coût (143 millions de dollars) étaient attribuables à la non-observance du schéma posologique contraceptif. L'accroissement du recours aux modes de CRAP a généré des économies de plus de 34 millions de dollars dans le cadre des trois scénarios de transition envisagés; les économies les plus importantes (35 millions de dollars) ont été constatées dans le cadre du scénario prévoyant que 10 % des utilisatrices de contraceptifs oraux adopteraient un mode de CRAP. La durée minimale d'utilisation d'un mode de CRAP nécessaire pour l'obtention d'économies était de 12 mois. Conclusion : Au Canada, le coût des GNP est considérable; de plus, une bonne partie de ce coût est attribuable à une observance imparfaite du schéma posologique contraceptif. L'accroissement du recours aux modes de CRAP pourrait mener à une baisse du taux de non-observance du schéma posologique contraceptif, ce qui entraînerait une baisse des taux de GNP et générerait des économies considérables, particulièrement chez les femmes de 20 à 29 ans.

Cost-effectiveness analysis of treatment of venous thromboembolism with rivaroxaban compared with combined low molecular weight heparin/vitamin K antagonist.

BACKGROUND: Venous thromboembolism (VTE) is a burden on healthcare systems. Standard treatment involves parenteral anticoagulation overlapping with a vitamin K antagonist, an approach that is effective but associated with limitations including the need for frequent coagulation monitoring. The direct oral anticoagulant rivaroxaban is similarly effective to standard therapy as a single-drug treatment for VTE and does not require routine coagulation monitoring. The objective of this economic evaluation was to estimate the cost-effectiveness of rivaroxaban compared with standard VTE treatment from a UK perspective. METHODS: A Markov model was constructed using data and probabilities derived from the EINSTEIN DVT and EINSTEIN PE studies of rivaroxaban and other published sources. Health outcomes included VTE rates, bleeding events avoided, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs). RESULTS: There was greater discounted quality-adjusted life expectancy with rivaroxaban than with standard therapy, irrespective of indication and treatment duration. Rivaroxaban was associated with per-patient cost savings for each treatment duration modelled (3, 6 and 12 months), and these were greatest with shorter durations. Rivaroxaban was found to be dominant (cheaper and more effective) and, therefore, cost-effective, in both patients with deep vein thrombosis and pulmonary embolism in all three treatment duration groups, and was also cost-effective in patients requiring lifelong anticoagulation (ICERs: £8677 per QALY and £7072 per QALY in patients with index deep vein thrombosis and pulmonary embolism, respectively). The cost-effectiveness of rivaroxaban was largely insensitive to variations in one-way sensitivity analysis. Probabilistic sensitivity analysis demonstrated that at a threshold of £20,000 per QALY, rivaroxaban had a consistent probability of being cost-effective, compared with LMWH/VKA treatment, of around 80% regardless of index VTE or duration of anticoagulation therapy (3, 6, 12 months or lifelong). CONCLUSIONS: This analysis suggests that rivaroxaban represents a cost-effective choice for acute treatment of deep vein thrombosis and pulmonary embolism and secondary prevention of VTE in the UK, compared with LMWH/VKA treatment, regardless of the required treatment duration.

Cost-effectiveness analysis of a low-dose contraceptive levonorgestrel intrauterine system in Sweden.

OBJECTIVE: To evaluate the cost-effectiveness of a novel intrauterine system, levonorgestrel intrauterine system 13.5 mg vs. oral contraception, in women at risk of unintended pregnancy. DESIGN: Cost-effectiveness model using efficacy and discontinuation data from published articles. SETTING: Societal perspective including direct and indirect costs. POPULATION: Women at risk of unintended pregnancy using reversible contraception. METHODS: An economic analysis was conducted by modeling the different health states of women using contraception over a 3-year period. Typical use efficacy rates from published articles were used to determine unintended pregnancy events. Discontinuation rates were used to account for method switching. MAIN OUTCOME MEASURES: Cost-effectiveness was evaluated in terms of the incremental cost per unintended pregnancy avoided. In addition, the incremental cost per quality-adjusted life-year was calculated. RESULTS: Levonorgestrel intrauterine system 13.5 mg generated costs savings of € 311,000 in a cohort of 1000 women aged 15-44 years. In addition, there were fewer unintended pregnancies (55 vs. 294) compared with women using oral contraception. CONCLUSION: Levonorgestrel intrauterine system 13.5 mg is a cost-effective method when compared with oral contraception. A shift in contraceptive use from oral contraception to long-acting reversible contraception methods could result in fewer unintended pregnancies, quality-adjusted life-year gains, as well as cost savings.

Achieving cost-neutrality with long-acting reversible contraceptive methods.

OBJECTIVES: This analysis aimed to estimate the average annual cost of available reversible contraceptive methods in the United States. In line with literature suggesting long-acting reversible contraceptive (LARC) methods become increasingly cost-saving with extended duration of use, it aimed to also quantify minimum duration of use required for LARC methods to achieve cost-neutrality relative to other reversible contraceptive methods while taking into consideration discontinuation. STUDY DESIGN: A three-state economic model was developed to estimate relative costs of no method (chance), four short-acting reversible (SARC) methods (oral contraceptive, ring, patch and injection) and three LARC methods [implant, copper intrauterine device (IUD) and levonorgestrel intrauterine system (LNG-IUS) 20 mcg/24 h (total content 52 mg)]. The analysis was conducted over a 5-year time horizon in 1000 women aged 20-29 years. Method-specific failure and discontinuation rates were based on published literature. Costs associated with drug acquisition, administration and failure (defined as an unintended pregnancy) were considered. Key model outputs were annual average cost per method and minimum duration of LARC method usage to achieve cost-savings compared to SARC methods. RESULTS: The two least expensive methods were copper IUD ($304 per women, per year) and LNG-IUS 20 mcg/24 h ($308). Cost of SARC methods ranged between $432 (injection) and $730 (patch), per women, per year. A minimum of 2.1 years of LARC usage would result in cost-savings compared to SARC usage. CONCLUSIONS: This analysis finds that even if LARC methods are not used for their full durations of efficacy, they become cost-saving relative to SARC methods within 3 years of use. IMPLICATIONS: Previous economic arguments in support of using LARC methods have been criticized for not considering that LARC methods are not always used for their full duration of efficacy. This study calculated that cost-savings from LARC methods relative to SARC methods, with discontinuation rates considered, can be realized within 3 years.

Direct costs of unintended pregnancy in the Russian federation.

BACKGROUND: In 2010, almost every third pregnancy in Russia was terminated, indicating that unintended pregnancy (UP) is a public health problem. OBJECTIVE: The aim of this study was to estimate the direct cost of UP to the healthcare system in Russia and the proportion attributable to using unreliable contraception. METHODS: A cost model was built, adopting a generic payer perspective with a 1-year time horizon. The analysis cohort was defined as women of childbearing age between 18 and 44 years actively seeking to avoid pregnancy. Model inputs were derived from published sources or government statistics with a 2012 cost base. To estimate the number of UPs attributable to unreliable methods, the model combined annual typical use failure rates and age-adjusted utilization for each contraceptive method. Published survey data was used to adjust the total cost of UP by the number of UPs that were mistimed rather than unwanted. Scenario analysis considered alternate allocation of methods to the reliable and unreliable categories and estimate of the burden of UP in the target sub-group of women aged 18-29 years. RESULTS: The model estimated 1,646,799 UPs in the analysis cohort (women aged 18-44 years) with an associated annual cost of US$783 million. The model estimated 1,019,371 UPs in the target group of 18-29 years, of which 88 % were attributable to unreliable contraception. The total cost of UPs in the target group was estimated at approximately US$498 million, of which US$441 million could be considered attributable to the use of unreliable methods. CONCLUSION: The cost of UP attributable to use of unreliable contraception in Russia is substantial. Policies encouraging use of reliable contraceptive methods could reduce the burden of UP.

Cost of unintended pregnancy in Norway: a role for long-acting reversible contraception.

OBJECTIVES: The objective of this study was to quantify the cost burden of unintended pregnancies (UPs) in Norway, and to estimate the proportion of costs due to imperfect contraceptive adherence. Potential cost savings that could arise from increased uptake of long-acting reversible contraception (LARC) were also investigated. METHODS: An economic model was constructed to estimate the total number of UPs and associated costs in women aged 15-24 years. Adherence-related UP was estimated using 'perfect use' and 'typical use' contraceptive failure rates. Potential savings from increased use of LARC were projected by comparing current costs to projected costs following a 5% increase in LARC uptake. RESULTS: Total costs from UP in women aged 15-24 years were estimated to be 164 million Norwegian Kroner (NOK), of which 81.7% were projected to be due to imperfect contraceptive adherence. A 5% increase in LARC uptake was estimated to generate cost savings of NOK 7.2 million in this group. CONCLUSIONS: The cost of UP in Norway is substantial, with a large proportion of this cost arising from imperfect contraceptive adherence. Increased LARC uptake may reduce the UP incidence and generate cost savings for both the health care payer and contraceptive user.

A cost-effectiveness analysis of subcutaneous interferon beta-1a 44mcg 3-times a week vs no treatment for patients with clinically isolated syndrome in Sweden.

OBJECTIVE: To assess the cost-effectiveness of subcutaneous interferon (sc IFN) beta-1a 44 mcg 3-times weekly (tiw) vs no treatment at reducing the risk of conversion to multiple sclerosis (MS) in patients with clinically isolated syndrome (CIS) in Sweden. METHODS: A Markov model was constructed to simulate the clinical course of patients with CIS treated with sc IFN beta-1a 44 mcg tiw or no treatment over a 40-year time horizon. Costs were estimated from a societal perspective in 2012 Swedish kronor (SEK). Treatment efficacy data were derived from the REFLEX trial; resource use and quality-of-life (QoL) data were obtained from the literature. Costs and outcomes were discounted at 3%. Sensitivity analyses explored whether results were robust to changes in input values and use of Poser criteria. RESULTS: Using McDonald criteria sc IFN beta-1a was cost-saving and more effective (i.e., dominant) vs no treatment. Gains in progression free life years (PFLYs) and quality-adjusted life-years (QALYs) were 1.63 and 0.53, respectively. Projected cost savings were 270,263 SEK. For Poser criteria cost savings of 823,459 SEK were estimated, with PFLY and QALY gains of 4.12 and 1.38, respectively. Subcutaneous IFN beta-1a remained dominant from a payer perspective. Results were insensitive to key input variation. Probabilistic sensitivity analysis estimated a 99.9% likelihood of cost-effectiveness at a willingness-to-pay threshold of 500,000 SEK/QALY. CONCLUSION: Subcutaneous IFN beta-1a is a cost-effective option for the treatment of patients at high risk of MS conversion. It is associated with lower costs, greater QALY gains, and more time free of MS. LIMITATIONS: The risk of conversion from CIS to MS was extrapolated from 2-year trial data. Treatment benefit was assumed to persist over the model duration, although long-term data to support this are unavailable. Cost and QoL data from MS patients were assumed applicable to CIS patients.

The burden of moderate/severe premenstrual syndrome and premenstrual dysphoric disorder in a cohort of Latin American women.

OBJECTIVES: The aim of this study was to investigate the relationship between symptom severity, cost, and impairment in women with moderate/severe premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD) in a Latin American setting. METHODS: A model was constructed based on analysis of an observational dataset. Data were included from four Latin American countries. Responder-level data were analysed according to four categories of symptom severity: Category 1 comprised Daily Record of Severity of Problems score 21 to 41.9, Category 2 score was 42 to 62.9, Category 3 score was 63 to 83.9, and Category 4 was a score of 84 or higher. Burden was estimated in terms of impact on job and activities using the modified work productivity and impairment questionnaire and affect on quality of life using the SF-12 questionnaire. Costs were estimated in Brazilian reals from a Brazilian private health care and societal perspective. The outputs of the analysis were estimates of burden, mean annual cost and affect on quality of life (as measured by quality adjusted life years) by symptom severity. Confidence intervals around key outcomes were generated through nonparametric bootstrapping. RESULTS: Analysis suggests a significant cost burden associated with moderate/severe PMS and PMDD with mean per patient annual costs estimated at 1618 BRL (95% confidence interval 957-2,481). Although the relationship between cost, quality of life, and severity was not clear, analysis showed a consistent relationship between disease severity and measures of disease burden (job and daily activity). Burden on activities increased with disease severity. CONCLUSIONS: Our analysis, conducted from a Latin American perspective, suggests a significant burden and an increasing impairment associated with moderate/severe PMS and PMDD.

A cost-effectiveness analysis of levodopa/carbidopa intestinal gel compared to standard care in late stage Parkinson's disease in the UK.

OBJECTIVE: Evaluation of cost-effectiveness of levodopa/carbidopa intestinal gel (LCIG), compared to standard care (SC) in patients with advanced Parkinson's disease (aPD) in the UK. DESIGN: Markov model to quantify costs and outcomes associated with LCIG versus SC in aPD patients at Hoehn and Yahr (H&Y) stages 3, 4 or 5 experiencing >50% OFF time per day. Time horizon was lifetime, LCIG treatment was assumed to last maximal 5 years after which patients revert to SC. Model comprised 12 aPD health states according to H&Y status and daily time spent in OFF state. Cost analyses are reported from a UK NHS and Personal Social Services perspective. Uncertainties were assessed through one-way sensitivity analyses. COMPARATORS: LCIG, providing patients with continuous dopaminergic stimulation to maximise functional ON time during the day and SC, defined as medically determined best available oral medication. MAIN OUTCOME MEASURES: Cost-effectiveness, based on quality adjusted life years gained, presented as an incremental cost-effectiveness ratio. RESULTS: Lifetime analysis yields an incremental cost per QALY of £36,024 for LCIG compared to SC (incremental cost £39,644, QALY gain 1.1). Results were sensitive to time on treatment, health state on treatment initiation, and estimates of long term benefit (OWSA results from £32,127 to £66,421 per QALY). Findings must be considered in the context of the study limitations which were mainly due to data availability constraints. CONCLUSIONS: LCIG is an effective treatment, reducing OFF time and improving quality of life in advanced PD. It provides value for money in levodopa-responsive aPD patients with severe motor fluctuations when no other treatment options are effective or suitable. Given LCIG is an orphan drug, it is reasonable to suggest that it may be considered cost-effective in the UK setting. However, further research is needed to complete current data gaps and increase robustness of the model.

The economic burden of advanced Parkinson's disease: an analysis of a UK patient dataset.

BACKGROUND: To evaluate the cost burden of patients with advanced Parkinson's disease (PD) according to the waking hours per day spent in OFF state. An analysis of resource use comprising medical services, professional care and informal care data from an observational, cross-sectional study was conducted. METHODS: A total of 60 physicians comprising 40 neurologists and 20 geriatricians across the UK participating in the Adelphi PD Disease Specific Programme took part. There were 302 PD patients at H&Y stages 3-5. Patients were characterised according to the percentage of time per day spent in OFF state (<25%, 26-50%, 51-75%, >75%). RESULTS: Average 12-monthly total costs increased according to the time spent in OFF state from £25,630 in patients spending less than 25% of their waking hours in OFF to £62,147 for patients spending more than 75% of their time in OFF. Overall, 7% of costs were attributed to direct medical care, while 93% were split between direct non-medical professional care (50%) and indirect informal care (43%). LIMITATIONS: Low patient numbers in the more advanced disease stages of PD led to very little or no data to directly inform some of the severe health states of the analysis. Data gaps were filled in with data derived from a regression analysis which may affect the robustness of the analysis. CONCLUSION: This study illustrates the increasing costs of advancing PD, in particular related to the time spent in OFF state, and identifies that the foremost cost burden is associated with the care needs of the patient rather than medical services.
