Abstract
OBJECTIVE The cost-effectiveness threshold (CET) is a key parameter to guide objective reimbursement decisions, yet very few countries have defined a reference CET, and there is no reference method for defining it. Our objective was to determine the factors explaining the author-reported CETs in the literature. METHODS Our systematic review targeted original articles referenced in EMBASE and published between 2010 and 2021. Selected studies had to use Quality-Adjusted Life-Year (QALY), and being conducted in high-income countries. Our explanatory variables were: estimated cost-effectiveness ratio (ICER), region of the world, source of funding, type of intervention, disease, year of publication, justification of the author-reported Cost-Effectiveness Threshold (ar-CET), economic perspective, and declaration of interest. Multivariable linear regression models implemented on R software were used, guided by a Directed Acyclic Graph. RESULTS Two hundred and fifty four studies were included. The mean ar-CET was €63,338/QALY (standard deviation (SD) 34,965) overall, and €37,748/QALY (SD 20,750) in studies conducted in the British Commonwealth. The ar-CET increased slightly with the ICER (+ 66€/QALY for each additional 10,000€/QALY in the ICER, 95% confidence interval (IC) [31-102], p < 0.001), was higher in the United States (+ 36,225€/QALY; IC [25,582; 46,869]) and Europe (+ 10,352€/QALY; IC [72; 20,631]) compared to the British Commonwealth (p < 0.001), and was higher when the ar-CET was not defined a priori (+ 22,393€/QALY; [5809; 38,876]) compared to state recommendations defined ar-CET (p < 0.001). CONCLUSIONS Our results underline the virtuous role of state recommendations in the choice of a low and homogeneous CET. We also highlight the need to integrate the a priori justification of the CET into good publishing guidelines.

Abstract
Collisions between ships and whales can pose a significant threat to the survival of some whale populations. The lack of robust and holistic assessments of the consequences of mitigation solutions often leads to poor compliance from the shipping industry. To overcome this, several papers support a regulatory approach to the management of whale-ship collisions through the International Maritime Organization (IMO), the UN agency responsible for maritime affairs. According to the IMO risk assessment approach, in order to compare the costs of implementing mitigation solutions and their benefits, there is a need for a well-defined risk evaluation criterion. To define such a criterion for whales, we have used an ecological-economic framework based on existence values and conservation objectives. As an illustration, we have applied our framework to the Mediterranean fin whale (Balaenoptera physalus) population and determined the cost of averting a whale fatality as a proxy for the societal benefits. More precisely, we have estimated the 'Cost of averting a Mediterranean fin whale fatality' of 562,462 (in 2017 US dollars); this corresponds to 637,790 USD when converted to 2021 US dollars. The societal benefits of solutions that reduce the risk to whales could therefore be weighed against the costs of shipping companies to implement such measures. This could lead to assessments that are more transparent and the introduction of mandatory measures to reduce ship strikes.

Abstract
Economic studies in healthcare are used to measure the cost and effectiveness of an intervention and are valuable in determining how healthcare resources can be distributed to achieve the greatest overall gain. Most economic studies in healthcare are cost-benefit analyses, cost-effectiveness analyses (CEAs), or cost-utility analyses (CUAs). CEAs and CUAs compare alternative interventions based on cost and effectiveness but are influenced by different methodologies and assumptions employed by researchers. The perspective from which an economic study is evaluated (the patient, the provider, the payor, or the society) should be carefully considered. The incremental cost effectiveness ratio (ICER) describes the difference between two interventions in cost and health outcomes and can be expressed in dollars per quality-adjusted life year (QALY). A threshold ICER <$50,000/QALY is often used to determine whether an intervention is cost-effective, in conjunction with patient factors, healthcare system factors, and opportunity cost associated with the intervention. The Consolidated Health Economic Evaluating Reporting Standards (CHEERS) statement provides guidelines for reporting healthcare economic studies. Key elements to be reported include the study design, target population and subgroups, time horizon, health outcomes, perspectives, comparison group, and sensitivity analyses performed. Economic studies are particularly important in orthopedics given the prevalence of musculoskeletal disease, high upfront costs, and potential quality of life improvements associated with orthopedic surgical procedures. An understanding of economic evaluations in healthcare is important to critically review the available literature.

Abstract
In his book, "More than Medicine: The Broken Promise of American Health," Robert Kaplan brings together extensive data to make the case that healthcare priorities in the USA need to place greater emphasis on behavioral, social and environmental determinants of health. Kaplan argues that the effect sizes for health outcomes resulting from environmental exposures, stress, and socioeconomic status are all much larger than are many traditional biological risk factors. There are discrepancies between estimates of how much the National Institutes of Health spends on behavioral and social sciences research, but an independent evaluation suggests it is <5% of the entire budget. Addressing this neglect requires advocacy and bringing together of like-minded organizations to promote more funding for behavioral interventions, health promotion and public health policies to address important contextual factors such as poverty, lack of education, and poor environmental conditions. Importantly, Kaplan argues that several metrics to integrate life expectancy and quality of life have been proposed and allow healthcare providers to prioritize the value of health over the volume of healthcare delivered. Although standards exist, there are still a limited number of studies on the cost-effectiveness and cost-utility of behavioral and public health interventions.

Abstract
Nutrient export from agricultural areas is among the main contributors to water pollution in various watersheds. Agricultural Beneficial Management Practices (BMPs) are commonly used to reduce excessive nutrient runoff and improve water quality. The successful uptake of BMPs not only depends on their effectiveness but also on their costs of implementation. This study conducts a set of cost-effectiveness analyses to help stakeholders identify their preferred combinations of BMPs in the Qu'Appelle River Basin, a typical watershed in the Canadian Prairies. The considered BMPs are related to cattle and cropping farms and are initially selected by agricultural producers in this region. The analyses use a water quality model to estimate the impact of implementing BMPs on nutrient export, and the cost estimation model to approximate the cost of implementing BMPs at tributary and watershed scales. Our results show that BMPs' effectiveness, total costs of implementation and costs per kilogram of nutrient abatement vary between tributaries. However, wetland conservation is among the optimal practices to improve water quality across the watershed. It is also found that the rates of BMP adoption by stakeholders can influence the effectiveness of practices in a large watershed scale, which highlights the importance of stakeholder engagement in water quality management. This type of analyses can help stakeholders choose single or a combination of BMPs according to their available budget and acceptable levels of reduction in nutrients.

Abstract
Background Both Deep Brain Stimulation (DBS) and Continuous intrajejunal Levodopa Infusion (CLI) are effective therapies for the treatment of Parkinson’s disease (PD). To our knowledge, no direct head-to-head comparison of DBS and CLI has been performed, whilst the costs probably differ significantly. In the INfusion VErsus STimulation (INVEST) study, costs and effectiveness of DBS and CLI are compared in a randomized controlled trial (RCT) in patients with PD, to study whether higher costs of one of the therapies are justified by superiority of that treatment. Methods A prospective open label multicentre RCT is being performed, with ancillary patient preference observational arms. Patients with PD who, despite optimal pharmacological treatment, have severe response fluctuations, bradykinesia, dyskinesias, or painful dystonia are eligible for inclusion. A total of 66 patients will be randomized. There is no minimal inclusion in the patient preference arms. The primary health economic outcomes are costs per unit on the Parkinson’s Disease Questionnaire-39 (PDQ-39) and costs per unit Quality-Adjusted Life Year (QALY) at 12 months. The main clinical outcome is patient-reported quality of life measured with the PDQ-39 at 12 months. Patients will additionally be followed during 36 months after initiation of the study treatment. Discussion The INVEST trial directly compares the costs and effectiveness of the advanced therapies DBS and CLI.

Abstract
Background Evidence from a retrospective analysis of multiple large phase iii trials suggested that primary tumour location (ptl) in RAS wild-type metastatic colorectal cancer (wtRAS mcrc) might have predictive value with respect to response to drug therapies. Recent studies also show a potential preferential benefit for epidermal growth factor inhibitors (egfris) for left-sided tumours. In the present study, we aimed to determine the incremental cost-effectiveness ratio (icer) for the first-line use of an egfri for patients with left-sided wtRAS mcrc. Methods We developed a state-transition model to determine the cost effectiveness of alternative treatment strategies in patients with left-sided mcrc:■ Standard of care■ Use of an egfri in first-line therapyThe cohort for the study consisted of patients diagnosed with unresectable wtRAS mcrc with an indication for chemotherapy and previously documented ptl. Model parameters were obtained from the published literature and calibration. The perspective was that of a provincial ministry of health in Canada. We used a 5-year time horizon and an annual discount rate of 1.5%. Results Selecting patients for first-line egfri treatment based on left-sided location of their colorectal primary tumour was more effective than the standard of care, resulting in an increase in quality-adjusted life-years (qalys) of 0.226 (or 0.644 life-years gained). However, the strategy was also more expensive, costing an average of $60,639 more per patient treated. The resulting icer was $268,094 per qaly. A 35% price reduction in the cost of egfri would be needed to make this strategy cost-effective at a willingness-to-pay threshold (wtp) of $100,000 per qaly. Conclusions Selective use of an egfri based on ptl was more cost-effective than unselected use of those agents; however, based on traditional wtp thresholds, it was still not cost-effective. While awaiting the elucidation of more precise predictive biomarkers that might improve cost-effectiveness, the price of egfris could be reduced to meet the wtp threshold.

Abstract
Background Although Option B+ may be more costly than Options B, it may provide additional health benefits that are currently unclear in Yunnan province. We created deterministic models to estimate the cost-effectiveness of Option B+. Methods Data were used in two deterministic models simulating a cohort of 2000 HIV+ pregnant women. A decision tree model simulated the number of averted infants infections and QALY acquired for infants in the PMTCT period for Options B and B+. The minimum cost was calculated. A Markov decision model simulated the number of maternal life year gained and serodiscordant partner infections averted in the ten years after PMTCT for Option B or B+. ICER per life year gained was calculated. Deterministic sensitivity analyses were conducted. Results If fully implemented, Option B and Option B+ averted 1016.85 infections and acquired 588,01.02 QALYs.The cost of Option B was US$1,229,338.47, the cost of Option B+ was 1,176,128.63. However, when Options B and B+ were compared over ten years, Option B+ not only improved mothers’ten-year survival from 69.7 to 89.2%, saving more than 3890 life-years, but also averted 3068 HIV infections between serodiscordant partners. Option B+ yielded a favourable ICER of $32.99per QALY acquired in infants and $5149per life year gained in mothers. A 1% MTCT rate, a 90% coverage rate and a 20-year horizon could decrease the ICER per QALY acquired in children and LY gained in mothers. Conclusions Option B+ is a cost-effective treatment for comprehensive HIV prevention for infants and serodiscordant partners and life-long treatment for mothers in Yunnan province, China. Option B+ could be implemented in Yunnan province, especially as the goals of elimination mother-to-child transmission of HIV and “90–90-90” achieved, Option B+ would be more attractive.

Abstract
BACKGROUND Bone metastases are highly prevalent in breast, prostate, lung and colon cancers. Their symptoms negatively affect quality of life and functionality and optimal management can mitigate these problems. There are two different targeted agents to treat them: bisphosphonates (pamidronate and zoledronic acid) and the monoclonal antibody denosumab. Estimates of cost-effectiveness are still mixed. OBJECTIVE To conduct a systematic review of economic studies that compares these two options. METHOD Literature search comprised eight databases and keywords for bone metastases, bisphosphonates, denosumab, and economic studies were used. Data were extracted regarding their methodologic characteristics and cost-effectiveness analyses. All studies were evaluated regarding to its methodological quality. RESULTS A total of 263 unique studies were retrieved and six met inclusion criteria. All studies were based on clinical trials and other existing literature data, and they had high methodological quality. Most found unfavorable cost-effectiveness for denosumab compared with zoledronic acid, with adjusted ICERS that ranged from $4638-87,354 per SRE avoided and from US$57,274-4.81 M. per QALY gained, which varied widely according to type of tumor, time horizon, among others. Results were sensitive to drug costs, time to first skeletal-related event (SRE), time horizon, and utility. CONCLUSIONS Denosumab had unfavorable cost-effectiveness compared with zoledronic acid in most of the included studies. New economic studies based on real-world data and longer time horizons comparing these therapeutic options are needed.

Abstract
PURPOSE Nearly 12 million children and adolescents in sub-Saharan Africa have lost one or both parents to AIDS. Within sub-Saharan Africa, Uganda has been greatly impacted, with an estimated 1.2 million orphaned children, nearly half of which have experienced parental loss due to the epidemic. Cost-effective and scalable interventions are needed to improve developmental outcomes for these children, most of whom are growing up in poverty. This article examines the direct impacts and cost-effectiveness of a savings-led family economic empowerment intervention, Bridges to the Future, that employed varying matched savings incentives to encourage investment in Ugandan children orphaned by AIDS. METHODS Using data from 48 primary schools in southwestern Uganda, we calculate per-person costs in each of the two treatment arms-Bridges (1:1 match savings) versus Bridges PLUS (1:2 match savings); estimate program effectiveness across outcomes of interest; and provide the ratios of per-person costs to their corresponding effectiveness. RESULTS At the 24-month postintervention initiation, children in the two treatment arms showed better results in health, mental health, and education when compared to the usual care condition; however, no statistically significant differences were found between treatment arms with the exception of school attendance rates which were higher for those in Bridges PLUS. Owing to the minimal cost difference between the Bridges and Bridges PLUS arms, we did not find substantial cost-effectiveness differences across the two treatment arms. CONCLUSION After 24 months, an economic intervention that incorporated matched savings yielded positive results on critical development outcomes for adolescents orphaned by AIDS in Uganda. The 1:1 and 1:2 match rates did not demonstrate variable levels of cost-effectiveness at 24-month follow-up, suggesting that governments intending to incorporate savings-led interventions within their social protection frameworks may not need to select a higher match rate to see positive developmental outcomes in the short term. Further research is required to understand intervention impacts and cost-effectiveness after a longer follow-up period.

BACKGROUND In Canada and elsewhere, pazopanib and sunitinib-tyrosine kinase inhibitors targeting the vascular endothelial growth factor receptors-are recommended as first-line treatment for patients with metastatic renal cell carcinoma (mrcc). A large randomized noninferiority trial of pazopanib versus sunitinib (comparz) demonstrated that the two drugs have similar efficacy; however, patients randomized to pazopanib experienced better health-related quality of life (hrqol) and nominally lower rates of non-study medical resource utilization. METHODS The cost-effectiveness of pazopanib compared with sunitinib for first-line treatment of mrcc from a Canadian health care system perspective was evaluated using a partitioned-survival model that incorporated data from comparz and other secondary sources. The time horizon of 5 years was based on the maximum duration of follow-up in the final analysis of overall survival from the comparz trial. Analyses were conducted first using list prices for pazopanib and sunitinib and then by assuming that the prices of sunitinib and pazopanib would be equivalent. RESULTS Based on list prices, expected costs were CA$10,293 less with pazopanib than with sunitinib. Pazopanib was estimated to yield 0.059 more quality-adjusted life-years (qalys). Pazopanib was therefore dominant (more qalys and lower costs) compared with sunitinib in the base case. In probabilistic sensitivity analyses, pazopanib was dominant in 79% of simulations and was cost-effective in 90%-100% of simulations at a threshold cost-effectiveness ratio of CA$100,000. Assuming equivalent pricing, pazopanib yielded CA$917 in savings in the base case, was dominant in 36% of probabilistic sensitivity analysis simulations, and was cost-effective in 89% of simulations at a threshold cost-effectiveness ratio of CA$100,000. CONCLUSIONS Compared with sunitinib, pazopanib is likely to be a cost-effective option for first-line treatment of mrcc from a Canadian health care perspective.

Abstract
AIMS To examine the cost-effectiveness of intravascular ultrasound (IVUS) use during percutaneous coronary intervention (PCI) with drug-eluting stents (DES) in treating coronary artery disease (CAD). METHODS AND RESULTS A Markov model was constructed with a lifetime horizon to compare costs and health outcomes between IVUS-guided PCI and PCI guided solely by angiography from an Italian healthcare payer perspective. The population examined included CAD patients undergoing PCI with DES. From a healthcare payer perspective, the resulting incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year was negative in the base-case scenario (i.e., IVUS benefit assumed to persist beyond the first year). When IVUS benefit was assumed to be limited to the first year, the ICER increased to €9,624. This conclusion remained consistent even when scenarios varied regarding the duration of the device's effect. Furthermore, benefits of using IVUS were greater for patients with acute coronary syndrome, renal insufficiency, and diabetes. CONCLUSIONS Using IVUS with angiography is a dominant strategy in Italy, and results demonstrate that it is desirable to target those at a greater risk of restenosis (i.e., patients with diabetes, chronic kidney disease, and acute coronary syndrome), who tend to benefit more from accurate stent implantation. Further information is necessary regarding the long-term benefits of IVUS, however sensitivity analysis presented in this research demonstrates a strong argument supporting the cost-effectiveness of IVUS.

Abstract
OBJECTIVE To be useful to policymakers and stakeholders, cost-effectiveness analyses (ceas) should be published in a timely manner and without bias. The aims of the present study were to examine the time between conference abstract presentation and subsequent publication, to determine the factors associated with time to publication, to evaluate potential publication bias, and to examine discrepancies in the results between abstract and publication. METHODS Abstracts of ceas presented at the annual meetings of the American Society of Clinical Oncology (asco), the American Society of Hematology (ash), and the International Society for Pharmacoeconomics and Outcomes Research (ispor) between 1997 and 2007 were reviewed. Time-to-event analysis was performed to assess the timeliness of publication and to examine factors associated with time to publication. Summary statistics were used to assess discrepancies in incremental cost-effectiveness ratios (icers) between abstract and publication. RESULTS Of 164 abstracts identified, 65 (39.6%) were subsequently published. The 1-, 2-, 3-, and 5-year publication rates were 12.8%, 25%, 34.2%, and 40.5% respectively. Abstracts were more likely to be published if presented at asco than at ispor (hazard ratio: 1.94; p = 0.038). There was no direct evidence of publication bias for abstracts with favourable icers. Comparing icers between abstracts and publications, the mean absolute difference was 23.8%; 50% of studies had a change in icer exceeding 10%. CONCLUSIONS Publication rates for ceas were low, and publication was not timely with respect to informing the decision-making process for funding. Abstract results often differed from publication results and cannot reliably be used in the decision-making process for funding.
