Practical Guidance for Including Future Costs in Economic Evaluations in The Netherlands: Introducing and Applying PAID 3.0

ObjectivesA consensus has been reached in The Netherlands that all future medical costs should be included in economic evaluations. Furthermore, internationally, there is the recognition that in countries that adopt a societal perspective estimates of future nonmedical consumption are relevant for decision makers as much as production gains are. The aims of this paper are twofold: (1) to update the tool Practical Application to Include Future Disease Costs (PAID 1.1), based on 2013 data, for the estimation of future unrelated medical costs and introduce future nonmedical consumption costs, further standardizing and facilitating the inclusion of future costs; and (2) to demonstrate how to use the tool in practice, showing the impact of including future unrelated medical costs and future nonmedical consumption in a case-study where a life is hypothetically saved at different ages and 2 additional cases where published studies are updated by including future costs.MethodsUsing the latest published cost of illness data from the year 2017, we model future unrelated medical costs as a function of age, sex, and time to death, which varies per disease. The Household Survey from Centraal Bureau Statistiek is used to estimate future nonmedical consumption by age.ResultsThe updated incremental cost-effectiveness ratios (ICERs) from the case studies show that including future costs can have a substantial effect on the ICER, possibly affecting choices made by decision makers.ConclusionThis article improves upon previous work and provides the first tool for the inclusion of future nonmedical consumption in The Netherlands.     

Don’t forget about the future: The impact of including future costs on the cost-effectiveness of adult pneumococcal conjugate vaccination with PCV13 in the Netherlands

BackgroundWhen vaccines increase longevity, vaccinated people may experience costs and benefits during added life-years. These future benefits and costs may include increased productivity as well as medical and non-medical costs. Such impacts should be considered in cost-effectiveness analyses (CEA) of vaccines but are often omitted. Here, we illustrate the impact of including future costs on the cost-effectiveness of vaccination against pneumococcus disease. We emphasize the relevance of differentiating cost estimates between risk groups.MethodsWe updated an existing Dutch CEA of vaccination against pneumococcus disease with the 13-valent pneumococcal conjugate vaccine (PCV13) to include all future medical and non-medical costs. We linked costs by age and risk with survival information and estimates of cases prevented per vaccination strategy based on the original study to calculate the impact of inclusion. Future medical costs were adjusted for relevant risk groups.ResultsFor the base-case strategy, the original incremental cost-effectiveness ratio (ICER) of PVC13 was €9,157 per quality adjusted life-year (QALY). Including all future medical costs increased the ICER to €28,540 per QALY. Also including future non-medical costs resulted in an ICER of €45,691 per QALY. The impact of future medical costs varied considerably per risk group and generally increased with age.Discussion and conclusionThis study showed a substantial effect of the inclusion of future costs on the ICER of vaccinating with PCV13. Especially when lives of people with underlying health conditions are extended, the impact of future medical costs is large. This inclusion may make vaccination a less attractive option, especially in relation to low thresholds as often applied for prevention. Although this raises important questions, ignoring these real future costs may lead to an inefficient use of healthcare resources. Our results may imply that prices for some vaccines need to be lowered to be cost-effective.     

Economic evaluation and the postponement of health care costs

The inclusion of medical costs in life years gained in economic evaluations of health care technologies has long been controversial. Arguments in favour of the inclusion of such costs are gaining support, which shifts the question from whether to how to include these costs. This paper elaborates on the issue how to include cost in life years gained in cost effectiveness analysis given the current practice of economic evaluations in which costs of related diseases are included. We combine insights from the theoretical literature on the inclusion of unrelated medical costs in life years gained with insights from the so-called 'red herring' literature. It is argued that for most interventions it would be incorrect to simply add all medical costs in life years gained to an ICER, even when these are corrected for postponement of the expensive last year of life. This is the case since some of the postponement mechanism is already captured in the unadjusted ICER by modelling the costs of related diseases. Using the example of smoking cessation, we illustrate the differences and similarities between different approaches. The paper concludes with a discussion about the proper way to account for medical costs in life years gained in economic evaluations.     

Unrelated medical care in life years gained and the cost utility of primary prevention: in search of a 'perfect' cost-utility ratio

An important subject of debate in cost-utility analysis of health care programmes is whether to include costs of unrelated medical care in life years gained. The inclusion of such costs is likely to be of consequence in the case of primary prevention. This paper presents different strategies regarding the inclusion not only of the costs, but also of the health effects of unrelated medical care in economic evaluations. Four different cost-utility ratios are presented and related to the criterion of internal consistency. In addition, the possibility to relate the ratios to a well-posed decision problem is analysed. An example computes the different ratios for smoking cessation interventions in different age groups. Including health care costs of unrelated medical care in life years gained increases cost utility ratios, but excluding unrelated medical costs favours smoking cessation interventions targeted at older smokers over those at younger smokers. We conclude that for primary prevention only a cost utility ratio that includes both the costs and effects of unrelated medical care meets the criterion of internal consistency and is related to a meaningful decision problem. Therefore, this type of cost-utility ratio should be preferred even if the data requirements may be substantial.     

Illustrating the impact of including future costs in economic evaluations: an application to end-stage renal disease care

There are strong theoretical arguments for including future costs for related and unrelated medical care and non-medical expenditures within economic evaluations. Nevertheless, there is limited data on how inclusion of such costs affects the cost effectiveness of medical interventions in practice. For a low-cost intervention that improves survival in end-stage renal disease (ESRD) patients, we sought to determine how the inclusion of future costs for related medical care (i.e. dialysis and transplantation) and for unrelated medical care and non-medical expenditure would affect the magnitude of the cost per QALY ratio. We performed a cost-utility analysis comparing hemodialysis using a synthetic dialyser (the current treatment of choice in Canada) with the historical gold-standard treatment (use of a cellulose dialyser). We contrasted the results of the analysis including and excluding various measures of future costs. While the inclusion of future costs for unrelated medical care and non-medical expenditures had a significant impact on the cost per QALY ratio, the size of the cost per QALY ratio was most sensitive to inclusion of future costs for related medical care. Our analysis shows that even relatively inexpensive interventions that extend survival of dialysis patients may not be cost-effective since, by extending survival, the extra outpatient dialysis costs that are incurred are large. Inclusion of such costs (which, in and of itself, is methodologically correct) in economic evaluations in this area may mitigate against the acceptance of interventions that are relatively inexpensive themselves but which improve patient survival.     

Value of an Integrated Home Dialysis Model in the United Kingdom: A Cost-Effectiveness Analysis

ObjectivesThis study aimed to determine the lifetime cost-effectiveness of increasing home hemodialysis as a treatment option for patients experiencing peritoneal dialysis technique failure compared with the current standard of care.MethodsA Markov model was developed to assess the lifetime costs, quality-adjusted life-years, and cost-effectiveness of increasing the usage an integrated home dialysis model compared with the current patient pathways in the United Kingdom. A secondary analysis was conducted including only the cost difference in treatments, minimizing the impact of the high cost of dialysis during life-years gained. Sensitivity and scenario analyses were performed, including analyses from a societal rather than a National Health Service perspective.ResultsThe base-case probabilistic analysis was associated with incremental costs of £3413 and a quality-adjusted life-year of 0.09, resulting in an incremental cost-effectiveness ratio of £36 341. The secondary analysis found the integrated home dialysis model to be dominant. Conclusions on cost-effectiveness did not change under the societal perspective in either analysis.ConclusionsThe base-case analysis found that an integrated home dialysis model compared with current patient pathways is likely not cost-effective. These results were primarily driven by the high baseline costs of dialysis during life-years gained by patients receiving home hemodialysis. When excluding baseline dialysis-related treatment costs, the integrated home dialysis model was dominant. New strategies in kidney care patient pathway management should be explored because, under the assumption that dialysis should be funded, the results provide cost-effectiveness evidence for an integrated home dialysis model.     

Catalog of Age- and Medical Condition—Specific Healthcare Costs in the United States to Inform Future Costs Calculations in Cost-Effectiveness Analysis

ObjectivesThis study aims to develop a catalog of annual age- and medical condition—specific healthcare costs per capita among those who are living at a certain age (survivors) and the costs attributable to death itself for those who die at that age (decedents) in the United States. These estimates can be used to inform future cost calculations in cost-effectiveness analysis (CEA).MethodsWe discussed a theoretical framework to incorporate futures costs in CEA. We used the nationally representative Medical Expenditure Panel Survey data to estimate costs among survivors and death costs. For survivors, we obtained cost estimates nonparametrically using kernel-based regression and locally weighted scatterplot smoothing. We estimated costs attributable to death using inverse probability weights comparing decedents with appropriately weighted survivors at a given age after controlling for more than 270 clinical condition classifications, demographics, and interactions. Cost estimates were expressed in 2019 US dollar and also separately by sex and specific clinical conditions.ResultsAverage healthcare costs per capita among survivors, expectedly, rose over age from $2062 (95% confidence interval [CI] $1553–$2478) during the first year of life to $14 307 (95% CI $13 706–$14 956) at 85 years or older. Average costs of death were $44 569 (95% CI $14 304–$67 369) during the first year of life and declined by –$321 (95% CI –$620 to –$22) per 1 year older.ConclusionsThe US catalog of healthcare costs among survivors and decedents can facilitate calculations of future costs in CEA as recommended by the Second Panel on Cost-Effectiveness in Health and Medicine.     

An Economic Evaluation of Salt Reduction Policies to Reduce Coronary Heart Disease in England: A Policy Modeling Study

ObjectivesDietary salt intake has been causally linked to high blood pressure and increased risk of cardiovascular events. Cardiovascular disease causes approximately 35% of total UK deaths, at an estimated annual cost of £30 billion. The World Health Organization and the National Institute for Health and Care Excellence have recommended a reduction in the intake of salt in people's diets. This study evaluated the cost-effectiveness of four population health policies to reduce dietary salt intake on an English population to prevent coronary heart disease (CHD).MethodsThe validated IMPACT CHD model was used to quantify and compare four policies: 1) Change4Life health promotion campaign, 2) front-of-pack traffic light labeling to display salt content, 3) Food Standards Agency working with the food industry to reduce salt (voluntary), and 4) mandatory reformulation to reduce salt in processed foods. The effectiveness of these policies in reducing salt intake, and hence blood pressure, was determined by systematic literature review. The model calculated the reduction in mortality associated with each policy, quantified as life-years gained over 10 years. Policy costs were calculated using evidence from published sources. Health care costs for specific CHD patient groups were estimated. Costs were compared against a “do nothing” baseline.ResultsAll policies resulted in a life-year gain over the baseline. Change4life and labeling each gained approximately 1960 life-years, voluntary reformulation 14,560 life-years, and mandatory reformulation 19,320 life-years. Each policy appeared cost saving, with mandatory reformulation offering the largest cost saving, more than £660 million.ConclusionsAll policies to reduce dietary salt intake could gain life-years and reduce health care expenditure on coronary heart disease.     

Cost-Effectiveness Analysis of Early versus Late Total Hip Replacement in Italy

ObjectiveTo assess the cost-effectiveness of early primary total hip replacement (THR) for functionally independent older adult patients with osteoarthritis (OA) versus 1) nonsurgical therapy followed by THR once the patient has progressed to a functionally dependent state (“delayed THR”) and 2) nonsurgical therapy alone (‘medical therapy’), from the Italian National Health Service perspective.MethodsIndividual patient data and evidence from published literature on disease progression, economic costs and THR outcomes in OA, including utilities, perioperative mortality rates, prosthesis survival, and costs of prostheses, THR, rehabilitation, follow-up, revision, and nonsurgical management, combined with population life tables, were synthesized in a Markov model of OA. The model represents the lifetime experience of a patient cohort following their treatment choice, discounting costs and benefits (quality-adjusted life-years) at 3% annually.ResultsAt age 65 years, the incremental cost per quality-adjusted life-year of THR over delayed THR was €987 in men and €466 in women; the figures for delayed THR versus medical therapy were €463 and €82, respectively. Among 80-year-olds, early THR is (extended) dominant. With gradual utility loss after primary THR, delaying surgery may be more appealing in women than in men in their 50s, because longer female life expectancy implies longer latter periods of low health-related quality of life (HRQOL) with early THR.ConclusionsTHR is cost-effective. Patients’ HRQOL benefits forgone with delayed THR are worth more than the costs it saves to the Italian National Health Service. This analysis might help to explain women's consistently lower HRQOL by the time of primary operation.     

The Continuing Story of the Cost-Effectiveness of Photoselective Vaporization of the Prostate versus Transuretheral Resection of the Prostate for the Treatment of Symptomatic Benign Prostatic Obstruction

BackgroundIn 2008, a UK assessment of technologies for benign prostatic obstruction concluded negatively about photoselective vaporization of the prostate (PVP), and the 2010 National Institute for Health and Care Excellence guidance caused several UK institutions to abandon PVP.ObjectiveTo reassess the costs and effects of PVP versus transurethral resection of the prostate (TURP) on the basis of most recent data.MethodsThe same model was used as in 2008. Transition probabilities were estimated using a Bayesian approach updating the 2008 estimates with data from two meta-analyses and data from GOLIATH, the latest and largest trial comparing PVP with TURP. Utility estimates were from the 2008 assessment, and estimates of resource utilization and costs were updated. Effectiveness was measured in quality-adjusted life-years gained, and costs are in UK pounds. The balance between costs and effects was addressed by multivariate sensitivity analysis.ResultsIf the 2010 National Institute for Health and Care Excellence analysis would have updated the cost-effectiveness analysis with figures from its own meta-analysis, it would have estimated the change in quality-adjusted life-years at −0.01 (95% confidence interval [CI] −0.05 to 0.01) instead of at −0.11 (95% CI −0.31 to −0.01) as in the 2008 analysis. The GOLIATH estimate of −0.01 (95% CI −0.07 to 0.02) strengthens the conclusion of near equivalence. Estimates of additional costs vary from £491 (£21−£1286) in 2008 to £111 (−£315 to £595) for 2010 and to £109 (−£204 to £504) for GOLIATH. PVP becomes cost saving if more than 32% can be carried out as a day case in the United Kingdom.ConclusionsThe available evidence indicates that PVP can be a cost-effective alternative for TURP in a potentially broad group of patients.     

Future Costs,Fixed Healthcare Budgets,and the Decision Rules of Cost‐Effectiveness Analysis

Life‐saving medical technologies result in additional demand for health care due to increased life expectancy. However, most economic evaluations do not include all medical costs that may result from this additional demand in health care and include only future costs of related illnesses. Although there has been much debate regarding the question to which extent future costs should be included from a societal perspective, the appropriate role of future medical costs in the widely adopted but more narrow healthcare perspective has been neglected. Using a theoretical model, we demonstrate that optimal decision rules for cost‐effectiveness analyses assuming fixed healthcare budgets dictate that future costs of both related and unrelated medical care should be included. Practical relevance of including the costs of future unrelated medical care is illustrated using the example of transcatheter aortic valve implantation. Our findings suggest that guidelines should prescribe inclusion of these costs. Copyright © 2014 John Wiley & Sons, Ltd.     

Can the Consideration of Societal Costs Change the Recommendation of Economic Evaluations in the Field of Rare Diseases? An Empirical Analysis

ObjectivesTo analyze whether the adoption of a societal perspective would alter the results and conclusions of economic evaluations for rare disease–related healthcare technologies.MethodsA search strategy involving all the active substances considered as orphan drugs by the European Medicines Agency plus a list of 76 rare diseases combined with economic-related terms was conducted on Medline and the Cost-Effectiveness Registry from the beginning of 2000 until November 2018. We included studies that considered quality-adjusted life years as an outcome, were published in a scientific journal, were written in English, included informal care costs or productivity losses, and separated the results according to the applied perspective.ResultsWe found 14 articles that fulfilled the inclusion criteria. Productivity losses were considered in 12 studies, the human capital approach being the method most frequently used. Exclusively, informal care was considered in 2 articles, being valued through the opportunity cost method. The 14 articles selected resulted in 26 economic evaluation estimations, from which incremental cost-utility ratio values changed from cost-effective to dominant in 3 estimates, but the consideration of societal costs only modified the authors’ conclusion in 1 study.ConclusionsThe presence of societal costs in the economic evaluation of rare diseases did not affect the conclusions of the studies except in a single specific case. In those studies where the societal perspective was considered, we did not find significant changes in the economic evaluation results due to the higher costs of treatments and the low quality-adjusted life-years gained.     

Cost Effectiveness of the Angiotensin Receptor Neprilysin Inhibitor Sacubitril/Valsartan for Patients with Chronic Heart Failure and Reduced Ejection Fraction in the Netherlands: A Country Adaptation Analysis Under the Former and Current Dutch Pharmacoeconomic Guidelines

Objectives

To describe the adaptation of a global health economic model to determine whether treatment with the angiotensin receptor neprilysin inhibitor LCZ696 is cost effective compared with the angiotensin-converting enzyme inhibitor enalapril in adult patients with chronic heart failure with reduced left ventricular ejection fraction in the Netherlands; and to explore the effect of performing the cost-effectiveness analyses according to the new pharmacoeconomic Dutch guidelines (updated during the submission process of LCZ696), which require a value-of-information analysis and the inclusion of indirect medical costs of life-years gained.

Optimizing the Position and Use of Omalizumab for Severe Persistent Allergic Asthma Using Cost-Effectiveness Analysis

BackgroundThere has been some controversy on whether the costs of omalizumab outweigh its benefits for severe persistent allergic asthma.ObjectivesThis study aimed to resolve the uncertainties and limitations of previous analyses and establish the cost-effectiveness of omalizumab under the list price and Patient Access Scheme (PAS) discounted price for the UK National Health Service.MethodsA decision-analytic model was developed to evaluate the long-term cost-effectiveness of omalizumab under the perspective of the National Health Service. Outcomes were expressed as quality-adjusted life-years (QALYs). Patient subgroups were defined post hoc on the basis of data collected in clinical trials: previous hospitalization, on maintenance oral corticosteroids, and three or more previous exacerbations.ResultsThe incremental cost-effectiveness ratio varied from £30,109 to £57,557 per QALY gained depending on the population considered using the PAS price; incremental cost-effectiveness ratios were over a third higher using the list price. Omalizumab is likely to be cost-effective at the threshold of £30,000 per QALY gained in the severe subgroups if the improvement in health-related quality of life from omalizumab is mapped from an asthma-specific measure to the EuroQol five-dimensional questionnaire (vs. the EuroQol five-dimensional questionnaire directly collected from patients) or asthma mortality refers to death after hospitalization from asthma (vs. asthma-mortality risk in the community).ConclusionsAlthough the cost-effectiveness of omalizumab is more favorable under the PAS price, it represents good value for money only in severe subgroups and under optimistic assumptions regarding asthma mortality and improvement in health-related quality of life. For these reasons, omalizumab should be carefully targeted to ensure value for money.     

Cost-Effectiveness of Mirabegron Compared with Antimuscarinic Agents for the Treatment of Adults with Overactive Bladder in the United Kingdom

BackgroundMirabegron, a first-in-class selective oral β₃-adrenoceptor agonist, has similar efficacy to most antimuscarinic agents and a lower incidence of dry mouth in patients with overactive bladder (OAB).ObjectivesTo evaluate the cost-effectiveness of mirabegron 50 mg compared with oral antimuscarinic agents in adults with OAB from a UK National Health Service perspective.MethodsA Markov model including health states for symptom severity, treatment status, and adverse events was developed. Cycle length was 1 month, and the time horizon was 5 years. Antimuscarinic comparators were tolterodine extended release, solifenacin, fesoterodine, oxybutynin extended release and immediate release (IR), darifenacin, and trospium chloride modified release. Transition probabilities for symptom severity levels and adverse events were estimated from a mirabegron trial and a mixed treatment comparison. Estimates for other inputs were obtained from published literature or expert opinion. Quality-adjusted life-years (QALYs) and total health care costs, including costs of drug acquisition, physician visits, incontinence pad use, and botox injections, were modeled. Deterministic and probabilistic sensitivity analyses were performed.ResultsBase-case incremental cost-effectiveness ratios ranged from £367 (vs. solifenacin 10 mg) to £15,593 (vs. oxybutynin IR 10 mg) per QALY gained. Probabilistic sensitivity analyses showed that at a willingness-to-pay threshold of £20,000/QALY gained, the probability of mirabegron 50 mg being cost-effective ranged from 70.2% versus oxybutynin IR 10 mg to 97.8% versus darifenacin 15 mg. A limitation of our analysis is the uncertainty due to the lack of direct comparisons of mirabegron with other agents; a mixed treatment comparison using rigorous methodology provided the data for the analysis, but the studies involved showed heterogeneity.ConclusionsMirabegron 50 mg appears to be cost-effective compared with standard oral antimuscarinic agents for the treatment of adults with OAB from a UK National Health Service perspective.     

Mifamurtide for High-Grade,Resectable, Nonmetastatic Osteosarcoma Following Surgical Resection: A Cost-Effectiveness Analysis

ObjectivesMifamurtide is an immune macrophage stimulant that when added to standard chemotherapy has demonstrated survival benefit for newly diagnosed osteosarcoma. The objectives of this study were to investigate the cost-effectiveness of adding mifamurtide to standard three- or four-agent chemotherapy for high-grade, resectable, nonmetastatic osteosarcoma following surgical resection and the issues of obtaining robust cost-effectiveness estimates for ultra-orphan drugs, given the shortage of data.MethodsAn economic evaluation was conducted from the perspective of the UK’s National Health Service as part of the manufacturer’s submission to the National Institute for Health and Care Excellence. The disease process was simplified to a transition through a series of health states, modeled by using a Markov approach. Data to inform the model were derived from patient-level data of Study INT-0133, published literature, and expert opinion. The final efficacy measure was life-years gained (LYG), and utilities were used to obtain quality-adjusted life-years (QALYs).ResultsFor a 60-year time frame and a discount rate of 3.5% for outcomes, patients receiving mifamurtide benefited from an average additional 1.57 years of life and 1.34 QALYs, compared with patients receiving chemotherapy alone, giving an incremental cost-effectiveness ratio (ICER) of £58,737 per LYG and £68,734 per QALY. Because treatment effects were both substantial in restoring health and sustained over a very long period, the National Institute for Health and Care Excellence changed its guidance to allow a discount of 1.5% for outcomes to be applied in these special circumstances. By using this discount factor, it was found that patients receiving mifamurtide had an average additional 2.58 years of life and 2.20 QALYs compared with patients receiving chemotherapy alone, resulting in an ICER of £35,765 per LYG and £41,933 per QALY.ConclusionMifamurtide’s ICER is cost-effective compared with that of other orphan and ultra-orphan drugs, for which prices and corresponding cost-effectiveness estimates are high.     

Economic Evaluation of the effect of Quitting Smoking on Weight Gains: Evidence from the United Kingdom

ObjectiveThis article estimated the causal effect of quitting smoking on body weight gains in the United Kingdom to evaluate whether savings in health costs deriving from smoking prevention and its related diseases are greater than the costs associated with increased obesity.MethodsWe used a longitudinal data set extracted from two waves (2004–2006) of the British Household Panel Survey, which includes information on smoking and a large number of sociodemographic variables. We modeled the effect of quitting smoking on body weight accounting for heterogeneous responses from individuals belonging to different clinical classes of body mass index (BMI) (i.e., overweight and obese individuals). National Health Service costs associated with smoking were then used to implement a cost-benefit analysis, comparing the advantages of smoking reductions with the costs associated with increased obesity.ResultsThe BMI was found to increase by 0.26 points for quitters compared with those who continued to smoke. The estimated BMI increase was larger for overweight (0.49 points) and obese (0.76 points) people. This result does not change when different control groups are examined. From an economic perspective, the National Health Service cost reductions attributable to quitting smoking were £156.81 million whereas the lost benefit for unintended increases in body weight was £24.07 million.ConclusionsThis article found that the health benefits associated with quitting smoking are greater than the costs associated with increased overweight and obesity.     

The Modeled Lifetime Cost-Effectiveness of Published Adherence-Improving Interventions for Antihypertensive and Lipid-Lowering Medications

ObjectiveWe sought to compare the cost-effectiveness of different interventions that have been shown to improve adherence with antihypertensive and lipid-lowering therapy, by combining a burden of nonadherence model framework with literature-based data on adherence-improving interventions.MethodsMEDLINE was reviewed for studies that evaluated ≥1 adherence intervention compared with a control, used an adherence measure other than self-report, and followed patients for ≥6 months. Effectiveness was assessed as Relative Improvement, ratio of adherence with an intervention versus control. Costs, standardized to 12 months and adjusted to 2007 US$, and effectiveness estimates for each intervention were entered into a previously published model designed to measure the burden of nonadherence with antihypertensive and lipid-lowering medications, in a hypertensive population. Outputs included direct medical costs and incremental costs per quality-adjusted life-year (QALY) gained.ResultsAfter screening, 23 eligible adherence-improving interventions were identified from 18 studies. Relative Improvement ranged from 1.13 to 3.60. After eliminating more costly/less effective interventions, two remained. Self-monitoring, reminders, and educational materials incurred total health-care costs of $17,520, and compared with no adherence intervention, had an incremental cost-effectiveness ratio (ICER) of $4984 per QALY gained. Pharmacist/nurse management incurred total health-care costs of $17,896, and versus self-monitoring, reminders, and education had an ICER of $6358 per QALY gained.ConclusionsOf published interventions shown to improve adherence, reminders and educational materials, and a pharmacist/nurse management program, appear to be cost-effective and should be considered before other interventions. Understanding relative cost-effectiveness of adherence interventions may guide design and implementation of efficient adherence-improving programs     

Cost-Effectiveness of Baseline Low-Dose Computed Tomography Screening for Lung Cancer: The Israeli Experience

ObjectiveReduced mortality with low-dose computed tomography (LDCT) lung cancer screening was demonstrated in a large randomized controlled study of high-risk individuals. Cost-effectiveness must be assessed before routine LDCT screening is considered. We aimed to evaluate the cost-effectiveness of LDCT lung cancer screening in Israel.MethodsA decision analytic framework was used to evaluate the decision to screen or not screen from the health system perspective. The screening arm included 842 moderate-to-heavy smokers aged 45 years or older, screened at Hadassah-Hebrew University Medical Center from 1998 to 2004. In the usual-care arm, stage distribution and stage-specific life expectancy were obtained from the Israel National Cancer Registry data for 1994 to 2006. Lifetime stage-specific costs were estimated from medical records of patients diagnosed and treated at Hadassah Medical Center in the period 2003 to 2004. The analysis considered possible biases—lead time, overdiagnosis, and self-selection. Cost per quality-adjusted-life-year (QALY) gained by screening was estimated.ResultsBase-case incremental cost per QALY gained was $1464 (2011 prices). Extensive sensitivity analysis affirmed the low cost per QALY gained. The cost per QALY gained is lower than $10,000 with probability 0.937 and is lower than $20,000 with probability 0.978.ConclusionsOur analysis suggests that baseline LDCT lung cancer screening in Israel presents a good value for the money and should be considered for inclusion in the National List of Health Services financed publicly.     

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

ObjectivesStopping 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.MethodsA 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.ResultsIn 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.ConclusionThis 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.
