Background Chikungunya and dengue are emerging diseases that have caused large outbreaks in various regions of the world. Both are both spread by Aedes aegypti and Aedes albopictus mosquitos. We developed a dynamic transmission model of chikungunya and dengue, calibrated to data from Colombia (June 2014 –December 2017). Methodology/Principal findings We evaluated the health benefits and cost-effectiveness of residual insecticide treatment, long-lasting insecticide-treated nets, routine dengue vaccination for children aged 9, catchup vaccination for individuals aged 10–19 or 10–29, and portfolios of these interventions. Model calibration resulted in 300 realistic transmission parameters sets that produced close matches to disease-specific incidence and deaths. Insecticide was the preferred intervention and was cost-effective. Insecticide averted an estimated 95 chikungunya cases and 114 dengue cases per 100,000 people, 61 deaths, and 4,523 disability-adjusted life years (DALYs). In sensitivity analysis, strategies that included dengue vaccination were cost-effective only when the vaccine cost was 14% of the current price. Conclusions/Significance Insecticide to prevent chikungunya and dengue in Columbia could generate significant health benefits and be cost-effective. Because of limits on diagnostic accuracy and vaccine efficacy, the cost of dengue testing and vaccination must decrease dramatically for such vaccination to be cost-effective in Colombia. The vectors for chikungunya and dengue have recently spread to new regions, highlighting the importance of understanding the effectiveness and cost-effectiveness of policies aimed at preventing these diseases.

Abstract Background Physical activity (PA) interventions capable of producing health benefits cost effectively are a public health priority across the Western world. ‘Men on the Move’ (MOM), a community-based PA intervention for men, demonstrated significant health benefits up to 52-weeks (W) post-baseline. This article details the economic evaluation of MOM with a view to determining its cost-effectiveness as a public health intervention to be rolled out nationally in Ireland. Methods Cost-effectiveness was determined by comparing the costs (direct and indirect) of the programme to its benefits, which were captured as the impact on quality-adjusted life-years (QALYs). For the benefits, cost–utility analysis was conducted by retrospectively adapting various health-related measures of participants to generate health states using Brazier et al.’s (2002) short form-6D algorithm. This in turn allowed for ‘utility measures’ to be generated, from which QALYs were derived. Results Findings show MOM to be cost-effective in supporting an ‘at risk’ cohort of men achieves significant improvements in aerobic fitness, weight loss and waist reduction. The total cost per participant (€125.82 for each of the 501 intervention participants), the QALYs gained (11.98 post-12-W intervention, or 5.3% health improvement per participant) and estimated QALYs ratio costs of €3723 represents a cost-effective improvement when compared to known QALY guidelines. Conclusions The analysis shows that the cost per QALY achieved by MOM is significantly less than the existing benchmarks of £20 000 and €45 000 in the UK and Ireland respectively, demonstrating MOM to be cost-effective.

Sex With Men

ObjectiveTo assess the cost-effectiveness of three testing strategies with or without light microscopic Gram-stained smear (GSS) evaluation for the detection of anogenital gonorrhoea among men who have sex with men (MSM) at the Amsterdam STI clinic using a healthcare payer perspective.MethodsThree testing strategies for MSM were compared: (1) GSS in symptomatic MSM only (currently practised strategy), (2) no GSS and (3) GSS in symptomatic and asymptomatic MSM. The three testing protocols include testing with nucleic acid amplification test to verify the GSS results in (1) and (3), or as the only test in (2). A transmission model was employed to calculate the influence of the testing strategies on the prevalence of anogenital gonorrhoea over 10 years. An economic model combined cost data on medical consultations, tests and treatment and utility data to estimate the number of epididymitis cases and quality-adjusted life years (QALY) associated with gonorrhoea. Incremental cost-effectiveness ratios (ICERs) for the testing scenarios were estimated. Uncertainty and sensitivity analyses were performed.ResultsNo GSS testing compared with GSS in symptomatic MSM only (current strategy) resulted in nine extra epididymitis cases (95% uncertainty interval (UI): 2–22), 72 QALYs lost (95% UI: 59–187) and €7300 additional costs (95% UI: −€185 000 (i.e.cost-saving) to €407 000) over 10 years. GSS testing in both symptomatic and asymptomatic MSM compared with GSS in symptomatic MSM only resulted in one prevented epididymitis case (95% UI: 0–2), 1.1 QALY gained (95% UI: 0.1–3.3), €148 000 additional costs (95% UI: €86 000 to–€217 000) and an ICER of €177 000 (95% UI: €67 000–to €705 000) per QALY gained over 10 years. The results were robust in sensitivity analyses.ConclusionsGSS for symptomatic MSM only is cost-effective compared with no GSS for MSM and with GSS for both symptomatic and asymptomatic MSM.

The Cost

Cataracts are the second most prioritized eye disease in the world. Cataracts are an expensive treatment because surgery is the only method that can treat the disease. This study aims to analyze the cost effectiveness of each operating procedure. Specifically, phacoemulsification and Small Incision Cataract Surgery (SICS) with Disability-Adjusted Life Years (DALYs) as the effectiveness indicator is used. This study is an observational analytic study with a prospective framework. The sample size is 130 patients who have undergone phacoemulsification and 25 patients who have undergone SICS. The DALY for phacoemulsification at Day-7 (D-7) is 0.3204, and at Day-21 (D-21), it is 0.3204, while the DALY for SICS at D-7 is 0.3060, and at D-21, it is 0.3158. The incremental cost effectiveness ratio (ICER) for cataract surgery at D-7 is USD $1872.49, and at D-21, it is USD $5861.71, whereas the Indonesian Gross Domestic Product (GDP) is USD $4174.90. In conclusion, the phacoemulsification technique is more cost effective than the SICS technique. The ICER value is very cost effective at D-7 post-surgery compared to at D-21 post-surgery because the ICER is less than 1 GDP per capita per DALY.

The Impact

Introduction People who inject drugs (PWID) in Ukraine have a high prevalence of hepatitis C virus (HCV). Since 2015, PWID have been receiving HCV treatment, but their impact and cost-effectiveness has not been estimated. Methods We developed a dynamic model of HIV and HCV transmission among PWID in Ukraine, incorporating ongoing HCV treatment (5,933 treatments) over 2015-2021; 46.1% among current PWID. We estimated the impact of these treatments and different treatment scenarios over 2021-2030: continuing recent treatment rates (2,394 PWID/year) with 42.5/100% among current PWID, or treating 5,000/10,000 current PWID/year. We also estimated the treatment rate required to decrease HCV incidence by 80% if preventative interventions are scaled-up or not. Required costs were collated from previous studies in Ukraine. We estimated the incremental cost-effectiveness ratio (ICER) of the HCV treatments undertaken in 2020 (1,059) by projecting the incremental costs and disability adjusted life years (DALYs) averted over 2020-2070 (3% discount rate) compared to a counterfactual scenario without treatment from 2020 onwards. Results On average, 0.4% of infections among PWID were treated annually over 2015-2021, without which HCV incidence would have been 0.6% (95%CrI: 0.3-1.0%) higher in 2021. Continuing existing treatment rates could reduce HCV incidence by 10.2% (7.8-12.5%) or 16.4% (12.1-22.0%) by 2030 if 42.5% or 100% of treatments are given to current PWID, respectively. HCV incidence could reduce by 29.3% (20.7-44.7%) or 93.9% (54.3-99.9%) by 2030 if 5,000 or 10,000 PWID are treated annually. To reduce incidence by 80% by 2030, 19,275 (15,134-23,522) annual treatments are needed among current PWID, or 17,955 (14,052-21,954) if preventative interventions are scaled-up. The mean ICER was US$828.8/DALY averted; cost-effective at a willingness-to-pay threshold of US$3,096/DALY averted (1xGDP). Implications Existing HCV treatment is cost-effective but has had little preventative impact due to few current PWID being treated. Further treatment expansion for current PWID could significantly reduce HCV incidence.

Abstract Objectives To assess the potential cost-effectiveness, health gains, and effects on health equality of eliminating industrial trans-fatty acids (TFAs) from the Australian food supply. Methods Markov cohort models were used to estimate the cost-effectiveness and policy impact on (ischemic heart disease) IHD burden and health equity of a national ban of industrial TFAs in Australia. Intake of TFA was assessed using the 2011–2012 Australian National Nutrition and Physical Activity Survey. The IHD burden attributable to TFA was calculated by comparing the current level of TFA intake to a counterfactual setting (0.5% energy per day from TFA; corresponding to TFA intake only from non-industrial sources, e.g., dairy foods). Policy costs, avoided IHD events and deaths, health-adjusted life years (HALYs) gained, and IHD-related healthcare costs saved were estimated over 10 years and lifetime of the adult Australian population. Cost-effectiveness was assessed by calculation of incremental cost-effectiveness ratios (ICER) using net policy cost and HALYs gained. Health benefits and health care cost changes were also assessed in subgroups based on socioeconomic status and remoteness. Results Elimination of industrial TFA was estimated to prevent 2,294 (95% uncertainty interval [UI]: 1,765; 2,851) IHD deaths and 9,931 (95% UI: 8,429; 11,532) IHD events over the first 10 years. The greatest health benefits were accrued to the most socioeconomically disadvantaged quintiles and among Australians living outside of major cities. The intervention was estimated to be cost-saving or cost-effective (i.e., ICER < 169,361 AUD/HALY) regardless of the time horizon, with ICERs of 1,073 (95% UI: dominant; 3,503) and 1,956 (95% UI: 1,010; 2,750) AUD/HALY over 10 years and life time, respectively. The TFA ban was estimated to be cost-saving or highly cost-effective in sensitivity analyses altering assumptions of post-intervention TFA intake, abundance of TFA-containing products, or discount rate. Conclusions A ban of industrial TFAs could avert substantial numbers of IHD events and deaths in Australia and will likely be a highly cost-effective strategy to reduce social-economic and urban-rural inequalities in health.

Abstract Background A recent study found that the gut microbiota, Lactobacillus and Bifidobacterium, have the ability to modulate the severity of malaria. The modulation of the severity of malaria is not however, the typical focal point of most widespread interventions. Thus, an essential element of information required before serious consideration of any intervention that targets reducing severe malaria incidence is a prediction of the health benefits and costs required to be cost-effective. Methods Here, we developed a mathematical model of malaria transmission to evaluate an intervention that targets reducing severe malaria incidence. We consider intervention scenarios of a 2-, 7-, and 14-fold reduction in severe malaria incidence, based on the potential reduction in severe malaria incidence caused by gut microbiota, under entomological inoculation rates occurring in 41 countries in sub-Saharan Africa. For each intervention scenario, disability-adjusted life years averted and incremental cost-effectiveness ratios were estimated using country specific data, including the reported proportions of severe malaria incidence in healthcare settings. Results Our results show that an intervention that targets reducing severe malaria incidence with annual costs between $23.65 to $30.26 USD per person and causes a 14-fold reduction in severe malaria incidence would be cost-effective in 15–19 countries and very cost-effective in 9–14 countries respectively. Furthermore, if model predictions are based on the distribution of gut microbiota through a freeze-dried yogurt that cost $0.20 per serving, a 2- to 14-fold reduction in severe malaria incidence would be cost-effective in 29 countries and very cost-effective in 25 countries. Conclusion Our findings indicate interventions that target severe malaria can be cost-effective, in conjunction with standard interventions, for reducing the health burden and costs attributed to malaria. While our results illustrate a stronger cost-effectiveness for greater reductions, they consistently show that even a limited reduction in severe malaria provides substantial health benefits, and could be economically viable. Therefore, we suggest that interventions that target severe malaria are worthy of consideration, and merit further empirical and clinical investigation.

In Shanghai, China, a polio immunization schedule of four inactivated polio vaccines (IPV) has been implemented since 2020, replacing the schedules of a combination of two IPVs and two bivalent live attenuated oral polio vaccines (bOPV), and four trivalent live attenuated oral polio vaccines (tOPV). This study aimed to assess the cost-effectiveness of these three schedules in infants born in 2016, in preventing vaccine-associated paralytic poliomyelitis (VAPP). We performed a decision tree model and estimated incremental cost-effectiveness ratio (ICER). Compared to the four-tOPV schedule, the two-IPV-two-bOPV schedule averted 1.2 VAPP cases and 16.83 disability-adjusted life years (DALY) annually; while the four-IPV schedule averted 1.35 VAPP cases and 18.96 DALY annually. Consequently, ICERVAPP and ICERDALY were substantially high for two-IPV-two-bOPV (CNY 12.96 million and 0.93 million), and four-IPV (CNY 21.24 million and 1.52 million). Moreover, net monetary benefit of the two-IPV-two-bOPV and four-IPV schedules was highest when the cost of IPV was hypothesized to be less than CNY 23.75 or CNY 9.11, respectively, and willingness-to-pay was hypothesized as CNY 0.6 million in averting one VAPP-induced DALY. IPV-containing schedules are currently cost-ineffective in Shanghai. They may be cost-effective by reducing the prices of IPV, which may accelerate polio eradication in Chinese settings.

Background:To assess from a societal perspective the cost-effectiveness of a school program to increase active transport in 10- to 11-year-old Australian children as an obesity prevention measure.Methods:The TravelSMART Schools Curriculum program was modeled nationally for 2001 in terms of its impact on Body Mass Index (BMI) and Disability-Adjusted Life Years (DALYs) measured against current practice. Cost offsets and DALY benefits were modeled until the eligible cohort reached age 100 or died. The intervention was qualitatively assessed against second stage filter criteria (‘equity,’ ‘strength of evidence,’ ‘acceptability to stakeholders,’ ‘feasibility of implementation,’ ‘sustainability,’ and ‘side-effects’) given their potential impact on funding decisions.Results:The modeled intervention reached 267,700 children and cost $AUD13.3M (95% uncertainty interval [UI] $6.9M; $22.8M) per year. It resulted in an incremental saving of 890 (95%UI −540; 2,900) BMI units, which translated to 95 (95% UI −40; 230) DALYs and a net cost per DALY saved of $AUD117,000 (95% UI dominated; $1.06M).Conclusions:The intervention was not cost-effective as an obesity prevention measure under base-run modeling assumptions. The attribution of some costs to nonobesity objectives would be justified given the program’s multiple benefits. Cost-effectiveness would be further improved by considering the wider school community impacts.

ObjectiveTo assess the cost-effectiveness of management strategies for patients presenting with chest pain and suspected coronary heart disease (CHD): (1) cardiovascular magnetic resonance (CMR); (2) myocardial perfusion scintigraphy (MPS); and (3) UK National Institute for Health and Care Excellence (NICE) guideline-guided care.MethodsUsing UK data for 1202 patients from the Clinical Evaluation of Magnetic Resonance Imaging in Coronary Heart Disease 2 trial, we conducted an economic evaluation to assess the cost-effectiveness of CMR, MPS and NICE guidelines. Health outcomes were expressed as quality-adjusted life-years (QALYs), and costs reflected UK pound sterling in 2016–2017. Cost-effectiveness results were presented as incremental cost-effectiveness ratios and incremental net health benefits overall and for low, medium and high pretest likelihood of CHD subgroups.ResultsCMR had the highest estimated QALY gain overall (2.21 (95% credible interval 2.15, 2.26) compared with 2.07 (1.92, 2.20) for NICE and 2.11 (2.01, 2.22) for MPS) and incurred comparable costs (overall £1625 (£1431, £1824) compared with £1753 (£1473, £2032) for NICE and £1768 (£1572, £1989) for MPS). Overall, CMR was the cost-effective strategy, being the dominant strategy (more effective, less costly) with incremental net health benefits per patient of 0.146 QALYs (−0.18, 0.406) compared with NICE guidelines at a cost-effectiveness threshold of £15 000 per QALY (93% probability of cost-effectiveness). Results were similar in the pretest likelihood subgroups.ConclusionsCMR-guided care is cost-effective overall and across all pretest likelihood subgroups, compared with MPS and NICE guidelines.
