Index Cases

BackgroundIn January 2016, clinical TB guidance in the UK changed to no longer recommend screening contacts of non-pulmonary, non-laryngeal (ETB) index cases. However, no new evidence was cited for this change, and there is evidence that screening these contacts may be worthwhile. The objective of this study was to estimate the cost-effectiveness of screening contacts of adult ETB cases and adult pulmonary or laryngeal TB (PTB) cases in London, UK.MethodsWe carried out a cross-sectional analysis of data collected on TB index cases and contacts in the London TB register and an economic evaluation using a static model describing contact tracing outcomes. Incremental cost-effectiveness ratios (ICERs) were calculated using no screening as the baseline comparator. All adult TB cases (≥15 years old) in London from 2012 to 2015, and their contacts, were eligible (2465/5084 PTB and 2559/6090 ETB index cases were included).ResultsAssuming each contact with PTB infects one person/month, the ICER of screening contacts of ETB cases was £78 000/quality-adjusted life-years (QALY) (95% CI 39 000 to 140 000), and screening contacts of PTB cases was £30 000/QALY (95% CI 18 000 to 50 000). The ICER of screening contacts of ETB cases was £30 000/QALY if each contact with PTB infects 3.4 people/month. Limitations of this study include the use of self-reported symptomatic periods and lack of knowledge about onward transmission from PTB contacts.ConclusionsScreening contacts of ETB cases in London was almost certainly not cost-effective at any conventional willingness-to-pay threshold in England, supporting recent changes to National Institute for Health and Care Excellence national guidelines.

The Impact

Severe combined immunodeficiency (SCID) can be detected through newborn bloodspot screening. In the UK, the National Screening Committee (NSC) requires screening programmes to be cost-effective at standard UK thresholds. To assess the cost-effectiveness of SCID screening for the NSC, a decision-tree model with lifetable estimates of outcomes was built. Model structure and parameterisation were informed by systematic review and expert clinical judgment. A public service perspective was used and lifetime costs and quality-adjusted life years (QALYs) were discounted at 3.5%. Probabilistic, one-way sensitivity analyses and an exploratory disbenefit analysis for the identification of non-SCID patients were conducted. Screening for SCID was estimated to result in an incremental cost-effectiveness ratio (ICER) of £18,222 with a reduction in SCID mortality from 8.1 (5–12) to 1.7 (0.6–4.0) cases per year of screening. Results were sensitive to a number of parameters, including the cost of the screening test, the incidence of SCID and the disbenefit to the healthy at birth and false-positive cases. Screening for SCID is likely to be cost-effective at £20,000 per QALY, key uncertainties relate to the impact on false positives and the impact on the identification of children with non-SCID T Cell lymphopenia.

Abstract Background and Aims Azathioprine has been for decades the drug of choice for maintenance therapy in patients with generalized ANCA vasculitis in remission. However, recent studies show that rituximab, a high-cost biological agent, which can be administrated in two different schedules, might be more effective, so it is necessary to know the cost- effectiveness. Our goal was to compare the cost-effectiveness of the 3 maintenance schemes: standard therapy with azathioprine; fixed-dose rituximab and rituximab tailored according to CD19 lymphocyte level and ANCA titres, from the perspective of the Colombian healthcare system. Method We designed a 5-year annual cycle Markov model with the following stages: remission, minor relapse, mayor relapse and death. Transition probabilities were obtained from a systematic review of the literature (Scopus and Pubmed). Following national guidelines for economic studies, costs (in 2018, 1 euro = 3489 Colombian pesos) were estimated based on national drug registries, and official tariff manuals for procedures and other resources. Main outcome was quality-adjusted life years (QALY), using lupus nephropathy as a proxy; values were obtained from Tufts CEA Registry and validated by local expert panel through a modified Delphi technique. Cost-effectiveness threshold was three-times per capita GDP (16.872 euros). Discount rate was 5%. Univariate and probabilistic sensitivity analyses were performed. Results Overall discounted 5-years costs were € 1149 for azathioprine; € 4025 for tailored rituximab and € 5221 for fixed rituximab. QALY gains were 2.94, 3.63 and 3.64, respectively. Both tailored and fixed rituximab were cost-effective (cost per QALY gained: € 4168 and € 5817 respectively), but tailored dosing was preferable due to its lower cost. Sensitivity analyses did not modify these results significantly. Conclusion To our knowledge this is the first economic evaluation that compare azathioprine with tailored and fixed rituximab regimens as a vasculitis maintenance treatment in adults with ANCA generalized. Due to its lower effectiveness azathioprine should not be the first line of treatment. Tailored rituximab should be a better option than fixed schedule due to its lower cost with similar effectiveness.

ObjectiveTo evaluate the cost-effectiveness of insertable cardiac monitors (ICMs) compared with standard of care (SoC) for detecting atrial fibrillation (AF) in patients at high risk of stroke (CHADS2 >2), using a UK National Health Service (NHS) perspective.MethodsUsing patient characteristics and clinical data from the REVEAL AF trial, a Markov model assessed the cost-effectiveness of detecting AF with an ICM compared with SoC. Costs and benefits were extrapolated across modelled patient lifetime. Ischaemic and haemorrhagic strokes, intracranial and extracranial haemorrhages and minor bleeds were modelled. Diagnostic and device costs were included, plus costs of treating stroke and bleeding events and costs of oral anticoagulants (OACs). Costs and health outcomes, measured as quality-adjusted life years (QALYs), were discounted at 3.5% per annum. One-way deterministic and probabilistic sensitivity analyses (PSA) were undertaken.ResultsThe total per-patient cost for ICM was £13 360 versus £11 936 for SoC (namely, annual 24 hours Holter monitoring). ICMs generated a total of 6.50 QALYs versus 6.30 for SoC. The incremental cost-effectiveness ratio (ICER) was £7140/QALY gained, below the £20 000/QALY acceptability threshold. ICMs were cost-effective in 77.4% of PSA simulations. The number of ICMs needed to prevent one stroke was 21 and to cause a major bleed was 37. ICERs were sensitive to assumed proportions of patients initiating or discontinuing OAC after AF diagnosis, type of OAC used and how intense the traditional monitoring was assumed to be under SoC.ConclusionsThe use of ICMs to identify AF in a high-risk population is cost-effective for the UK NHS.

IntroductionAn estimated 69 million traumatic brain injuries (TBI) occur each year worldwide, with most in low-income and middle-income countries. The CRASH-3 randomised trial found that intravenous administration of tranexamic acid within 3 hours of injury reduces head injury deaths in patients sustaining a mild or moderate TBI. We examined the cost-effectiveness of tranexamic acid treatment for TBI.MethodsA Markov decision model was developed to assess the cost-effectiveness of treatment with and without tranexamic acid, in addition to current practice. We modelled the decision in the UK and Pakistan from a health service perspective, over a lifetime time horizon. We used data from the CRASH-3 trial for the risk of death during the trial period (28 days) and patient quality of life, and data from the literature to estimate costs and long-term outcomes post-TBI. We present outcomes as quality-adjusted life years (QALYs) and 2018 costs in pounds for the UK, and US dollars for Pakistan. Incremental cost-effectiveness ratios (ICER) per QALY gained were estimated, and compared with country specific cost-effective thresholds. Deterministic and probabilistic sensitivity analyses were also performed.ResultsTranexamic acid was highly cost-effective for patients with mild TBI and intracranial bleeding or patients with moderate TBI, at £4288 per QALY in the UK, and US$24 per QALY in Pakistan. Tranexamic acid was 99% and 98% cost-effective at the cost-effectiveness thresholds for the UK and Pakistan, respectively, and remained cost-effective across all deterministic sensitivity analyses. Tranexamic acid was even more cost-effective with earlier treatment administration. The cost-effectiveness for those with severe TBI was uncertain.ConclusionEarly administration of tranexamic acid is highly cost-effective for patients with mild or moderate TBI in the UK and Pakistan, relative to the cost-effectiveness thresholds used. The estimated ICERs suggest treatment is likely to be cost-effective across all income settings globally.

To evaluate the relative cost-effectiveness of nicotine replacement therapy (NRT) and bupropion SR for smoking cessation, the authors reviewed published studies and developed a decision analytic model from the UK National Health Services perspective. Irrespective of the methods or assumptions involved, the results of published studies consistently indicated that NRT for smoking cessation is cost-effective. No published studies have evaluated the relative cost-effectiveness of bupropion SR for smoking cessation. The results of the decision analyses indicated that, as compared with advice or counseling alone, the incremental cost per life-years saved is about $1,441~$3,455 for NRT, $920~$2,150 for bupropion SR, and $1,282~$2,836 for NRT plus bupropion SR. The cost-effectiveness of adding NRT and bupropion SR to advice or counseling for smoking cessation is better than many other accepted health care interventions.

Abstract Abstract 4181 Introduction: Lenalidomide plus dexamethasone (Len+Dex) is approved by EMA for patients with multiple myeloma (MM) who have received at least 1 prior therapy. In the wake of NICE's guidance on Thalidomide and Bortezomib TA 228 for 1st-line treatment of MM, Len+Dex may be the only available novel therapy option with potential to extend survival beyond traditional therapies for patients failing the NICE recommended initial treatments; thalidomide or bortezomib both in combination with melphalan and prednisone. Therefore, economic modelling was undertaken to evaluate the cost-effectiveness of Len+Dex from the perspective of the National Health Service (NHS), England and Wales. Methods: An Excel-based individual simulation model was developed to account for disease history which affects time-to-progression (TTP) and overall survival (OS) in relapse refractory MM patients. The OS for each individual within the model was calculated as the combination of that patient's TTP and post progression survival (PPS). The TTP efficacy was derived from a subgroup analysis of patients from the MM-009/010 pivotal trials who had received only 1 prior therapy. The derived equation for TTP included parameters for treatment response, Len+Dex treatment effect and certain baseline characteristics of patients with only 1 prior therapy. The PPS for patients within the model was also derived from the MM-009/010 trials; however, since 47% of patients on Dex switched to Len+Dex at progression, there was a significant Len+Dex effect in the Dex PPS. To account for this, the Dex PPS was calibrated using the longer follow up from the UK Medical Research Council (MRC) trials. Resource use for monitoring and adverse events was obtained via a survey of expert hematologists in the UK. Costs were taken from NHS sources and included a Patient Access Scheme where patients received Len free of charge beyond 26 cycles of use. Utility values were taken from published literature and applied to patients prior to progression (based on their best response rate achieved) and after progression. The robustness of the model results were assessed by sensitivity analyses whereby individual model parameters were varied across their confidence intervals (CI). Results reported include life-years (LY), quality-adjusted life-years (QALY), costs, cost per LY gained and cost per QALY gained. NICE technology appraisal methodology guidelines were followed when modelling over a lifetime horizon and applying a 3.5% discount rate for future benefits and costs. All costs presented are in British pounds. Results: Len+Dex had a substantial increase in health-related outcomes compared to Dex alone, with LYs of 5.37 vs. 2.15 and QALYs of 3.69 vs. 1.49, respectively. The associated drug costs for Len+Dex over the patients' lifetime were higher: however, survival benefits accrued over the same time period offset the cost differences between the two regimens, resulting in a cost per LY gained of 20,639 and per QALY gained of 30,153. The model results remained robust to sensitivity analysis conducted on most parameters and utility estimates. The only parameter that affected the results was the adjustment factor for Dex survival when varied across its 95% CI (see table). Discussion: These results indicated that Len+Dex at 2nd line is cost-effective for a novel drug in an orphan disease compared to Dex alone. Despite Len+Dex only being recommended by NICE for use in MM patients with 2 or more prior therapies (with the recent NICE decision to allow thalidomide and Velcade in de novo patients), treatment alternatives for 2nd line therapy with novel agents is more limited. It is important for clinicians to consider the costs and benefits of 2nd line therapy. This analysis demonstrated that Len+Dex is cost-effective for 2nd line patients and meets the commonly quoted cost per QALY threshold of 30,000.

IntroductionMyelofibrosis (MF) is a rare (annual incidence estimated to be 1/100,000 in Europe), chronic hematologic disorder associated with morbidity and mortality as well as the risk of evolution to acute myeloid leukemia. Ruxolitinib (Jakavi®, Novartis) is the first JAK 1/2 inhibitor approved by the FDA and EMA in 2011 in treating MF. Ruxolitinib is considered a high-cost and life-time treatment. UK-based estimates of the cost of treatment are in the region of GBP43,000/year/patient (in 2013). Against the background of the challenge of treatments for rare diseases reaching cost-effectiveness thresholds, this study identified, collected, and appraised the available evidence on the cost-effectiveness of ruxolitinib in the treatment of MF.MethodsA systematic approach was taken to conducting the literature review. Databases searched included PubMed, EMBASE, MEDLINE, and the Cochrane Library based on search terms informed by PICO: myelofibrosis, ruxolitinib, best available therapy/standard of care, and cost-effectiveness/cost-utility/pharmacoeconomics. The search was limited to studies published in the English language. A narrative synthesis was used to evaluate studies and the CHEERS checklist to explore the quality of reporting of the cost-effectiveness analysis.ResultsThe narrative synthesis included five studies conducted in the UK, Portugal, Chile, Canada, and Finland. All cost-effectiveness analyses used data from the same two large, randomized controlled, double-blind, phase III studies (COMFORT-I and -II). Ruxolitinib was compared to the best available therapy (BAT), including hydroxyurea, no medication, and prednisone/prednisolone. Perspectives and included costs varied among analyses. Markov models and discrete state cohort models were used to evaluate the cost-effectiveness and clinical benefit was measured in quality-adjusted life years (QALY) or life years (LY) gained.These analyses estimated the base-case incremental cost-effectiveness ratios (ICER) per QALY of (converted into USD, if appropriate, at the historic average annual exchange rate) GBP44,905 in the UK (2013; USD 70,226), EUR40,000 in Portugal (2016; USD44,272), USD54,500 (2016), CAD61,444 in Canada (2012; USD61,474), and EUR42,367 in Finland (2015; USD42,027). Based upon the cost-effectiveness thresholds applied in each of these countries, ruxolitinib was found to be universally cost-effective, albeit with price adjustments as part of the wider pricing and reimbursement processes used in these countries.ConclusionsRuxolitinib was found to be cost-effective in treating MF informed by different types of models and from different perspectives; however, there was some uncertainty around available data due to limited data sources.

AbstractPharmacogenetics/pharmacogenomics have enabled the detection of risk of human leukocyte antigen (HLA) variants for clozapine-induced agranulocytosis/granulocytopenia (CIAG). To apply this evidence to the clinical setting, we compared the cost-effectiveness of the proposed “HLA-guided treatment schedule” and the “current schedule” being used in Japan and the United Kingdom (UK) (absolute neutrophil count (ANC) cutoff at 1500/mm3); in the “HLA-guided treatment schedules,” we considered a situation wherein the HLA test performed before clozapine initiation could provide “a priori information” by detecting patients harboring risk of HLA variants (HLA-B*59:01 and “HLA-B 158T/HLA-DQB1 126Q” for Japanese and Caucasian populations, respectively), a part of whom can then avoid CIAG onset (assumed 30% “prevention rate”). For the primary analysis, we estimated the incremental cost-effectiveness ratio (ICER) of “HLA-guided treatment schedule” and “current schedule” used in Japan and the UK, using a Markov model to calculate the cost and quality-adjusted life years (QALYs) over a 10-year time period. Furthermore, as an explorative analysis, we simulated several situations with various ANC cutoffs (1000/mm3 and 500/mm3) and plotted the cost/QALYs for each option to identify the best, or estimate the next best candidate option applicable in actual clinical settings. The primary probabilistic analysis showed that the “HLA-guided treatment schedule” was more cost effective than the “current schedule”; the ICER was £20,995 and £21,373 for the Japanese and the UK populations, respectively. Additional simulation revealed that the treatment option of ANC cutoff at 500/mm3 without HLA screening was the most cost-effective option; however, several options may be candidates to break away from the “current schedule” of ANC cutoff at 1500/mm3. Owing to its cost-effectiveness, we propose such pharmacogenetic-guided/pharmacogenomic-guided clozapine treatment for use in the real-world setting, which provides key information for optimization of clinical guidelines for high-risk patients for gradual change of clozapine treatment schedule under the safety consideration.

Bacillus Calmette–Guerin (BCG), the only available vaccine for tuberculosis (TB), has been applied for decades. The Indonesian government recently introduced a national TB disease control programme that includes several action plans, notably enhanced vaccination coverage, which can be strengthened through underpinning its favourable cost-effectiveness. We designed a Markov model to assess the cost-effectiveness of Indonesia’s current BCG vaccination programme. Incremental cost-effectiveness ratios (ICERs) were evaluated from the perspectives of both society and healthcare. The robustness of the analysis was confirmed through univariate and probabilistic sensitivity analysis (PSA). Using epidemiological data compiled for Indonesia, BCG vaccination at a price US$14 was estimated to be a cost-effective strategy in controlling TB disease. From societal and healthcare perspectives, ICERs were US$104 and US$112 per quality-adjusted life years (QALYs), respectively. The results were robust for variations of most variables in the univariate analysis. Notably, the vaccine’s effectiveness regarding disease protection, vaccination costs, and case detection rates were key drivers for cost-effectiveness. The PSA results indicated that vaccination was cost-effective even at US$175 threshold in 95% of cases, approximating the monthly GDP per capita. Our findings suggest that this strategy was highly cost-effective and merits prioritization and extension within the national TB programme. Our results may be relevant for other high endemic low- and middle-income countries.

Objective To compare the cost-effectiveness of sialendoscopy with gland excision for the management of submandibular gland sialolithiasis. Study Design Cost-effectiveness analysis. Setting Outpatient surgery centers. Methods A Markov decision model compared the cost-effectiveness of sialendoscopy versus gland excision for managing submandibular gland sialolithiasis. Surgical outcome probabilities were found in the primary literature. The quality of life of patients was represented by health utilities, and costs were estimated from a third-party payer’s perspective. The effectiveness of each intervention was measured in quality-adjusted life-years (QALYs). The incremental costs and effectiveness of each intervention were compared, and a willingness-to-pay ratio of $150,000 per QALY was considered cost-effective. One-way, multivariate, and probabilistic sensitivity analyses were performed to challenge model conclusions. Results Over 10 years, sialendoscopy yielded 9.00 QALYs at an average cost of $8306, while gland excision produced 8.94 QALYs at an average cost of $6103. The ICER for sialendoscopy was $36,717 per QALY gained, making sialendoscopy cost-effective by our best estimates. The model was sensitive to the probability of success and the cost of sialendoscopy. Sialendoscopy must meet a probability-of-success threshold of 0.61 (61%) and cost ≤$11,996 to remain cost-effective. A Monte Carlo simulation revealed sialendoscopy to be cost-effective 60% of the time. Conclusion Sialendoscopy appears to be a cost-effective management strategy for sialolithiasis of the submandibular gland when certain thresholds are maintained. Further studies elucidating the clinical factors that determine successful sialendoscopy may be aided by these thresholds as well as future comparisons of novel technology.
