Cost–Utility Analysis of Supervised Inspiratory Muscle Training Added to Post-COVID Rehabilitation Program in the Public Health System of Brazil

Objectives: This study aims to provide model-based cost–utility estimates for the addition of inspiratory muscle training (IMT) in COVID-19 pulmonary rehabilitation (PR). Methods: A cohort model comparing IMT with PR (intervention group) to IMT with only PR (control group) was used. The payer perspective from the Unified Health System in Brazil was adopted. Effectiveness parameters: Effectiveness was measured in quality-adjusted life years (QALYs). Probabilistic sensitivity analyses were performed using 1000 Monte Carlo simulations. A beta probability distribution was assumed for utilities, and a gamma distribution was applied to the costs. A cost-effectiveness threshold of BRL 40.000/QALYs was applied. Results: As the threshold of BRL 40.000/QALYs, we obtained 512 (51.2%) simulations that can be considered cost-effective to IMT added in PR programs. IMT added in PR treatment was more expensive (USD 317.73 versus USD 293.93) and more effective (incremental utility of 0.03 to INT group) than PR alone. The incremental cost-effectiveness ratio (ICER) was 793.93 USD/QALY. Conclusions: IMT added to PR is a cost-effective alternative compared with PR for post-COVID-19 patients. This strategy may result in net cost savings and improvements in the QALYs for these patients.

Cost-Effectiveness of Bivalent Respiratory Syncytial Virus Prefusion F Vaccine for Prevention of Respiratory Syncytial Virus Among Older Adults in Greece

Background/Objectives: To evaluate the health benefits, costs, and cost-effectiveness of vaccination with bivalent respiratory syncytial virus stabilized prefusion F vaccine (RSVpreF) for the prevention of lower respiratory tract disease caused by respiratory syncytial virus (RSV) in Greek adults 60 years of age and older. Methods: A Markov model was adapted to simulate lifetime risk of health and economic outcomes from the public payer’s perspective over a lifetime horizon. Epidemiology, vaccine effectiveness, utilities, and direct medical costs (EUR, 2024) were obtained from published studies, official sources, and local experts. Model outcomes included the number of medically attended RSV cases, stratified by care setting (i.e., hospital, emergency department [ED], outpatient visits [OV]), and attributable RSV-related deaths, costs, life years (LY), quality-adjusted life-years (QALY), and incremental cost-effectiveness ratios (ICERs) of RSVpreF vaccination compared with no vaccination. Results: The model projected 258,170 hospitalizations, 112,248 ED encounters, 1,201,604 OV, and 25,463 deaths related to RSV in Greek older adults resulting in direct medical costs of EUR 1.6 billion over the lifetime horizon. Assuming RSV vaccination would reach the same coverage rates as pneumococcal and influenza programmes, 18,118 hospitalizations, 7874 ED encounters, 48,079 OV, and 1706 deaths could be prevented over the modelled time horizon. The health benefits associated with RSVpreF contributed to an incremental gain of 10,976 LYs and 7230 QALYs compared with no vaccination. The incremental analysis reported that vaccination with RSVpreF was estimated to be a cost-effective strategy resulting in ICERs of EUR 12,991 per LY gained, EUR 19,723 per QALY gained, and EUR 7870 per hospitalized RSV case avoided compared with no vaccination. Conclusions: Vaccination with RSVpreF was a cost-effective strategy for the prevention of RSV disease in Greek adults over 60 years of age. The introduction of RSV vaccination can improve public health by averting RSV cases and deaths and has the potential to fulfil an unmet medical need.

Cost-Effectiveness of Salt Substitution and Antihypertensive Drug Treatment in Chinese Prehypertensive Adults.

Recent guidelines recommend antihypertensive drug treatment for prehypertensive individuals with blood pressure between 130/80 and 139/89 mm Hg. This study evaluates the cost-effectiveness of 3 interventions in Chinese prehypertensive adults: salt substitution, antihypertensive drug treatment, and their combination. We developed a Markov cohort model to estimate cardiovascular disease (CVD) events, costs, and quality-adjusted life years (QALYs) over a lifetime. Data from the China Kadoorie Biobank informed the simulation. Costs and utilities were drawn from published sources. We evaluated the cost-effectiveness of salt substitution alone, antihypertensive drug treatment alone, and a combination of the 2, focusing on the overall prehypertensive population, those at high CVD risk, and different starting ages (40, 50, 60, and 70 years). Incremental cost-effectiveness ratios (ICERs) were calculated per QALY gained. Salt substitution at age 40 years is the only cost-effective strategy for prehypertensive individuals, with an ICER of $6413.62/QALY. For those at high CVD risk, the combination intervention starting at age 40 years is most cost-effective, with an ICER of $2913.30/QALY. Interventions initiated at younger ages yielded greater CVD reductions and lower ICERs. For example, a combined intervention at age 40 years reduces CVD events by 5.3% with an ICER of $2913.30/QALY, compared with 4.9% and $32 635.33/QALY at age 70 years. These results were consistent across sensitivity analyses. In China, replacing usual salt with a salt substitute is more cost-effective than treating prehypertensive individuals over the age of 40 years with antihypertensive drugs. Furthermore, starting intervention at a younger age in prehypertensive adults can result in even greater cost savings.

The cost-effectiveness of a digitally enabled telerehabilitation program delivered nationally to patients in Australia

Abstract Introduction Traditionally delivered cardiac rehabilitation (CR) programs have considerable benefits, yet access and participation remains low. Emerging digital health models offer promise in healthcare delivery, but their benefits and impact on healthcare utilization and cost-effectiveness are uncertain. We conducted a cost-effectiveness analysis of a telehealth program with a CR mobile app for post-hospitalization coronary heart disease (CHD) patients. Purpose To assess whether a digitally enabled CR program is cost-effective compared with a propensity matched usual care control group in the Australian health system. Methods Patients were recruited nationally, through a health insurer, following hospitalization for CHD. Participants received weekly telehealth consultations for up to 8 weeks, supplemented by use of an mHealth app. Using administrative private health insurance claims data, we assessed differences in hospital costs, mortality rates and bed days at 12-months post discharge. Incremental cost effectiveness ratios (ICERS) were calculated to determine the cost per deaths prevented and cost per bed days saved for the digital-CR group (n=133) compared with usual care (n=266). Results Among the cohort, 36% lived in regional/rural areas, 70% were male and the mean age was 68 years. The mean total hospital all cause readmission costs at 12-months were $1,488 AUD less in the digital-CR group ($16,411) compared to the usual care group ($17,899). Digital-CR had fewer total hospital days relative to the usual care group (median of 2 vs 3 days) and patients in the digital-CR group had a significantly lower mortality rate at 12-months post discharge. The ICERs were -$337 per 100 patient deaths prevented and -$3,033 per median bed days saved. Conclusion The implementation of a digital-CR program demonstrates cost-effectiveness for patients with CHD when compared to usual care. Thus, advocating for the widespread availability of digital-CR programs as an option for CHD patients following hospital discharge is warranted.

Screening for congenital Chagas disease in a non-endemic area: a cost-effectiveness analysis

Abstract Background Due to climate changes, immigration, and globalization, Chagas Disease (CD) also afflicts nations without vector transmission. In Europe, congenital CD (cCD) is a significant public health issue, perpetuating the disease: it is crucial to perform CD screening in pregnant women at risk, as the treatment of infants is effective in eradicating the infection. Only a few European regions have a definite algorithm for diagnosing cCD, but no official guidance has been published at the national or European level. To support policymakers, this study aims to outline a cost-effectiveness analysis of CD screening in non-endemic areas, such as Italy, in pregnant women born or arriving from endemic countries and in their newborns. Methods To measure the economic impact of cCD screening, a decision tree model will be used to compare the test option (screening, diagnosis, treatment, follow-up) with no test option (no screening, progression of disease). Model parameters will be taken from relevant scientific literature. The primary outcome will be the Incremental Cost-Effectiveness Ratio (ICER) between the two options. Sensitivity analyses will be conducted to determine how changes in prevalence, transmission rate, screening adherence, and treatment adherence may affect the ICER. Results We expect the ‘test’ option to be cost-effective even with significant reductions in prevalence, transmission rate, adherence to screening or treatment. Threshold levels of these variables will allow to critically extend the results to areas with reduced immigration, patchy distribution of migrants at risk, health logistical limitations, and limited access to care for immigrants. Conclusions Our findings can help policymakers implement official screening programs and diagnostic algorithms for cCD in Italy and other non-endemic countries. This contributes to SDG 3 by combating the spread and burden of neglected tropical diseases and contributing to maternal, child, and migrant health. Key messages • Screening for congenital Chagas Disease in a non-endemic area may be cost-effective and cost-saving. • Study findings could provide useful information for health policymakers to combat Chagas Disease in Europe.

Cost-effectiveness of respiratory syncytial virus adjuvanted vaccine in Portuguese aged ≥ 60 years

Abstract Background Respiratory syncytial virus (RSV) infections are one of the leading causes of lower respiratory tract disease among adults aged ≥60 years in Europe. This study aims to assess the potential public health impact of the RSVPreF3 OA adjuvanted vaccine, the first approved preventive intervention for the older adult population in Portugal. Methods A monthly-cycle static Markov model was developed to assess RSVPreF3 OA adjuvanted vaccine impact on adults aged 60 years and older in Portugal. A single dose of RSVPreF3 OA adjuvanted vaccine was compared to no-vaccination over a three-year time-horizon. The model captures lower respiratory tract disease (LRTD) RSV cases, hospitalizations, deaths, and healthcare resource utilization. Data inputs were based on local published literature, supplemented by the best available data when local information was lacking. Results Based on preliminary analysis considering 75% vaccine coverage, model outputs estimate that RSVPreF3 OA adjuvanted vaccine can prevent 71,433 LRTD cases requiring medical attendance, 11,067 hospitalizations, 1,793 intensive care unit admissions and 1,003 deaths. The model estimates that 32 adults need to be vaccinated to avoid one RSV LRTD case, 207 adults need to be vaccinated to avoid one hospitalization and 2,283 adults need to be vaccinated to avoid one death. The incremental cost-effectiveness ratio was estimated at 9,541€, hence the RSVPreF3 OA adjuvanted vaccine is cost-effective compared to no vaccination. Conclusions The results demonstrate a strong preventive impact of the RSVPreF3 OA adjuvanted vaccine on health outcomes and healthcare resource utilization in adults ≥60 years, leading to a significant public health benefit. This result emphasizes the importance of preventing RSV to preserve the health and well-being of Portugal’s older adults. In addition, data from ongoing studies may enhance precision and extensive sensitivity analyses validate the robustness of the model’s input assumptions. Key messages • This study shows the robust evidence of RSVPreF3 OA adjuvanted vaccine to improve public health by preventing thousands of hospitalizations and deaths among ≥60 years, in Portugal. • Vaccinating adults aged ≥ 60 years with RSVPreF3 OA adjuvanted vaccine in Portugal is a cost-effective strategy.

Cost-effectiveness analysis of Chagas disease screening in pregnant women and their infants in Italy

Abstract Background Currently, Chagas disease (CD) is widespread in European nations that host notable populations from Latin America. Vertical transmission is a pathway for the spread of the disease in countries where it is not endemic. Due to socio-economic disparities, CD is a public health concern in non-endemic regions, raised by migration phenomena in vulnerable population groups who face similar hindrances as those most at risk in endemic areas. The aim is to evaluate the cost-effectiveness of CD screening versus no screening in pregnant women and their infants in Italy. Methods A Bayesian Markov model was employed to compare the CD screening versus the no screening alternative. Model parameters were sourced from pertinent scientific literature. A lifetime perspective was adopted, aligning with the perspective of the Italian National Health Service. The Eurozone threshold was applied. Costs and benefits were discounted at a rate of 3%. Gibbs sampling served as the algorithm for Bayesian inference. Uncertainty was addressed through a probabilistic sensitivity analysis (PSA) and a value of information analysis (VOI), depicted via the Cost-Effectiveness Acceptability Curve (CEAC) and Expected Value of Perfect Information (EVPI). Results were presented as the Incremental Cost-Effectiveness Ratio (ICER). Results The base case results showed that CD screening was cost-effective, with an ICER of €5,112 [€1,850 - €10,043]. Furthermore, according to the CEAC, the screening option exhibited the greatest probability of being cost-effective across all thresholds. Additionally, the EVPI per mother was €818 based on a threshold of €50,000/diagnosis. Conclusions Implementing a structured CD screening program also in non-endemic countries has the potential for early detection and treatment. This contributes to SDG 3 by improving access to healthcare, preventing transmission, and reducing the disease burden as well as informing public health policies for marginalised populations. Key messages • This study proves that screening for CD in pregnant women and their infants in a non-endemic area is a cost-effective strategy and possibly cost-saving in the long term. • Study findings could support a wider implementation of CD screening in Italy by informing health policy-makers in their decision-making process.

Semaglutide for the secondary prevention of cardiovascular disease in people with overweight or obesity, but without diabetes: a cost-effectiveness analysis

Abstract Background The recently published trial, SELECT (Semaglutide Effects on Cardiovascular Outcomes in People with Overweight or Obesity) [1], was the first study to demonstrate that the glucagon-like peptide 1 receptor agonist, semaglutide, was superior to placebo in reducing the risk of major cardiovascular events in people with existing cardiovascular disease (CVD) and a body mass index of ≥27kg/m² but without diabetes. Despite the promising clinical benefits, the high cost of the medication has raised concerns about its financial viability and accessibility within healthcare systems. Purpose To explore whether use of semaglutide in addition to standard care (background use of lipid lowering, anti-hypertensive and/or anti-platelet therapies) for the secondary prevention of CVD in people with overweight or obesity is cost effective from the Australian healthcare perspective. Methods A Markov model was developed based on the SELECT trial, to evaluate the clinical outcomes and costs of a hypothetical population treated with semaglutide versus placebo over 20 years. With each annual cycle, subjects were at risk of having non-fatal CVD events (MI or stroke) or dying. Treatment efficacy, transition probabilities, and utilities were derived from the SELECT trial and published literature. Costs were obtained from Australian sources. The cost of semaglutide at a dosage of 2.4 mg/week (in line with SELECT) was estimated to be ~A$80 per week or A$4175 per year. The main outcome of interest was the incremental cost-effectiveness ratio (ICER) in terms of cost per year of life saved (YoLS) and cost per quality-adjusted life year (QALY) gained. All outcomes and costs were discounted by 5% per year. Costs are reported in 2023 Australian dollars (A$). Results Over a 20 year time horizon, treatment of 1000 hypothetical subjects with overweight or obesity and existing CVD with semaglutide compared to placebo prevented 126 non-fatal CVD events and 81 deaths, and yielded an additional 0.46 discounted life years and 0.48 discounted QALYs per person. The difference in total discounted costs was A$43,955 per person. This equated to ICERs of A$99,853 per YoLS and A$96,055 per QALY gained. Conclusions Assuming a willingness-to-pay-threshold of A$50,000 per QALY gained, semaglutide would not be considered cost-effective for the secondary prevention of CVD in people with overweight or obesity in Australia at current prices. A price reduction of 52% to less than A$2000 per year would be required for it to be considered a cost-effective treatment strategy in this setting. Given the modest event rates reported in SELECT, cost-effectiveness is likely to improve if use of semaglutide is targeted to higher risk groups. Moreover, SELECT primarily focused on cardiovascular benefits, however data supporting the impact of semaglutide on a number of other weight-related complications are anticipated and will inform a more holistic understanding of its cost effectiveness.

Decision-analytic modelling of costs & benefits of adding sigmoidoscopy to CRC screening in Germany

Abstract Background In Germany, a colorectal cancer (CRC) screening programme is in place that entitles individuals to a stool test or colonoscopy. However, less than half of those eligible participate. The inclusion of an additional screening option, such as the evidence-based sigmoidoscopy, could lead to a higher overall participation rate, but also to individuals preferring the additional option to the more effective colonoscopy. The objective of this modelling study is to estimate the impact of offering sigmoidoscopy as an additional option for CRC screening in Germany. Methods A life-time mathematical model (Markov model) is developed to analyse the long-term effects of the additional offer of sigmoidoscopy on benefits (prevalence, mortality, health-related quality of life (HRQoL)), costs, and cost-effectiveness. The model is based on systematic literature reviews and real-world healthcare data. It incorporates disease development, sensitivity and specificity of the options, compliance rates, survival probabilities and background mortality. A discrete choice experiment (DCE) was conducted to estimate the future uptake of the options (stool test, colonoscopy, sigmoidoscopy, no screening) based on stated preferences of n = 666 individuals. Results Adding sigmoidoscopy leads to greater effectiveness of the CRC screening programme in terms of increased screening participation, increased adenoma detection, decreased disease-specific mortality, and improved discounted HRQoL. However, it also incurs higher costs. The incremental cost-effectiveness ratios (ICER) for men and women are €507 per quality-adjusted life year gained (QALYg) and €74 per QALYg, respectively. Conclusions The results indicate that the inclusion of sigmoidoscopy in the German CRC screening programme would be cost-effective and that sigmoidoscopy should be piloted in practice. The expanded programme has the potential to enhance the program’s effectiveness, improve health outcomes, and reduce the burden of CRC. Key messages • Expanding the CRC screening programme may increase overall participation, resulting in higher costs, but also greater effectiveness in detecting more adenomas, reducing mortality, improving HRQoL. • Introducing sigmoidoscopy in Germany appears cost-effective and justifies practical piloting to enhance CRC screening efficacy and health outcomes.

Cost-effectiveness of semaglutide for secondary prevention of cardiovascular disease in the United States

Abstract Background In the SELECT trial, semaglutide produced a 20% reduction in the composite of cardiovascular death, non-fatal myocardial infarction (MI), and non-fatal stroke in individuals with overweight or obesity who did not have diabetes but had established pre-existing cardiovascular disease (CVD). Cost is an important barrier to widespread uptake of semaglutide, particularly in the US, and the cost-effectiveness for the secondary prevention of CVD is uncertain. Purpose To evaluate the cost-effectiveness of semaglutide vs. no obesity treatment for the secondary prevention of CVD from a US healthcare sector perspective. Methods The CVD Policy Model is an established, validated simulation model of fatal and non-fatal CVD outcomes and costs in the US population. Using data from the National Health and Nutrition Examination Survey, we created a nationally representative cohort of SELECT-eligible individuals (age ≥45, BMI ≥27kg/m2, no diabetes, pre-existing CVD). Healthcare costs associated with acute and chronic CVD were estimated from national survey and claims data and inflated to 2023 US dollars. The simulated control arm received usual care; the intervention arm received weekly semaglutide 2.4mg injections (assuming 8% discontinuation, which occurs year one). We reproduced the effectiveness of semaglutide based on results of the SELECT trial primary cardiovascular composite endpoint (non-fatal MI, non-fatal strokes and CVD death). The base case assumed 7% of patients receiving semaglutide developed injection-site reactions. Monthly cost of semaglutide was assumed to be $717 (US price net of rebates and discounts), but this was varied in sensitivity analyses. The analysis adopted a health system perspective over lifetime horizon. Results Approximately 4.7 million US adults would meet SELECT trial eligibility criteria. Over a lifetime horizon, semaglutide is projected to avert 538,000 major adverse cardiovascular events (241,000 nonfatal MIs; 80,000 nonfatal stokes, and 217,000 cardiovascular deaths) at an incremental cost of $613 billion. The incremental cost effectiveness ratio for semaglutide was $443,000 per quality-adjusted life year (QALY) gained. In order to meet cost-effectiveness thresholds of $50,000/QALY, $100,000/QALY, $150,000/QALY, drug costs would have to decline 90%, 79%, and 69% respectively. In sensitivity analyses, lowering drug cost to the current UK price (~ $220 per patient per month) would improve the incremental cost-effectiveness of semaglutide to <$150,000 per QALY gained, a potential upper threshold for cost-effectiveness in the US. Conclusion Widespread uptake of semaglutide in the SELECT-eligible U.S. population would prevent a large number of cardiovascular events, but its use would be low economic value at current US prices. Lowering prices in line with those in Europe (e.g., monthly price from $717 to $223) would make the therapy cost-effective at a threshold of $150,000 per QALY gained.

Cost impact of the use of a universal cardiac implantable electronic devices remote monitoring solution: results of the Evidence RM study

Abstract Background Remote monitoring (RM) is considered the standard of care for patients with cardiac implantable electronic devices (CIED). In 2023 the HRS/EHRA/APHPRS/LAHRS expert consensus highlighted the potential interest of alert-based monitoring and the use of a third-party platform for RM management. By lightening the RM workload for clinical staff, valuable time and resources can be redirected towards patient care. Purpose This study aims to assess the impact on healthcare expenditures of the adoption of a Universal, vendor-neutral, and alert-focused remote monitoring (RM) platform for CIED in France, as opposed to the Conventional RM conducted via device specific manufacturers' platforms. Methods This study utilizes the French National Health Database (SNDS) to evaluate the effectiveness of RM solutions among patients with implantable cardioverter defibrillators (ICD), including cardiac resynchronization therapy defibrillators (CRT-D). All patients under RM were categorized based on the type of monitoring, either the Universal RM or the Conventional RM. The analysis was conducted on year 2019 and included only patients maintaining consistent RM solutions and device types throughout the entirety of the study period. To mitigate potential biases, costs were adjusted according to age, gender, device type, year of first implantation, year of RM initiation, medical center experience with RM, and Elixhauser score for comorbidities. Results Study cohort consisted of 36,401 patients (age 67.3 ± 13.0 years / male 78.4% / CRT-D 40.1%), 1,482 patients followed using the Universal RM platform and 34,419 patients monitored with the Conventional RM solutions. The study findings revealed a 4% decrease in corrected total costs and a notable 17.8% reduction in hospital costs among patients utilizing the Universal RM. Analysis further identified that this decrease in hospital expenses was primarily influenced by a reduction of the costs associated with cardiovascular diseases. Conversely, the group utilizing the Universal RM experienced a 7.9% increase in total outpatient costs compared to Conventional RM, while ambulatory visit costs remained unchanged. As costs incurred by patients were not included, total costs may however be underestimated. Patients under the Universal RM solution may benefit of more proactive preventive measures delivered through outpatient care. By addressing issues preemptively, critical conditions may be averted, enhancing overall patient management, and diminishing hospital costs. The adoption of a third-party Universal platform may thus yield to cost savings, exemplified by a negative Incremental Cost-Effectiveness Ratio (ICER) of -103€ per Day Alive and Out of Hospital (DAOH) as observed in this study. Conclusions The use of a third-party Universal RM platform showed a positive impact in terms of costs reduction for the French healthcare system on this ICD population.

Cost-effectiveness of mineralocorticoid receptor antagonists in heart failure with reduced ejection fraction: the brazilian case with bayesian networks and markov influence diagrams

Abstract Background Heart failure (HF) is one of the leading causes of death worldwide, with a significant burden in middle-income countries, such as Brazil. Mineralocorticoid receptor antagonists (MRAs) have been established as a cornerstone in the treatment of HF with reduced ejection fraction (HFrEF), but their adoption has faced obstacles. Until recently, spironolactone was the only MRA available in Brazil, with restricted use due to associated side effects, such as gynecomastia and hyperkalemia. However, the introduction of new MRAs, such as finerenone and eplerenone, has the potential to change the therapeutic landscape. Understanding the cost-effectiveness of these agents in the Brazilian healthcare context is essential to optimize HF management. Methods A Bayesian Network approach complemented by Markov Influence Diagrams was employed to estimate incremental cost-effectiveness ratios (ICERs), presented in international dollars (Int$) gained per quality-adjusted life year (QALYs). Discontinuation rates for MRAs were incorporated into the model, reflecting real-world clinical practice, along with a 5% annual discount rate for both costs and effectiveness. To inform our model, a comprehensive systematic review was conducted, followed by a network meta-analysis (NMA) to assess the comparative effectiveness of ARMs. Data on incident cardiovascular outcomes were derived from a Brazilian real-world cohort of 1,098 patients with HFrEF. All cost assessments were made from the perspective of the Brazilian public health system, with values converted to Int$. Results The NMA highlighted that spironolactone [HR:0.75 (95%CI 0.67-0.84)], eplerenone [HR:0.84 (95%CI 0.77-0.93)] and finerenone [HR:0.90 (95%CI 0.82-0.98)] significantly reduced the relative risk of all-cause mortality compared to no MRA utilization. Notably, eplerenone significantly reduced hospitalizations due to HF [HR:0.60 (95%CI 0.41-0.90)] compared to no MRA therapy, with spironolactone and finerenone showing HRs of 0.68 (95%CI 0.40-1.17) and 0.83 (95%CI 0.59-1.15) . The analysis also revealed a notably higher risk of MRA discontinuation for finerenone (22%) and spironolactone (51%) compared to eplerenone. In cost-effectiveness comparisons, finerenone was dominated by alternatives, while eplerenone exhibited an ICER of Int$2,614 (95%CI 1,851-3,470)/QALY when compared to spironolactone. Both spironolactone and eplerenone emerged as cost-effective options when compared to no MRA therapy, with eplerenone being particularly favorable below the willingness-to-pay threshold of Int$8,900 per QALY. Conclusions In the Brazilian healthcare context, eplerenone will likely be the most cost-effective MRA compared to spironolactone, offering both a reduction in HF-related hospitalizations and a lower discontinuation rate. These findings underscore the value of integrating cost-effectiveness analyzes into healthcare decision-making processes.

Multiple myeloma: What is the most cost-effective imaging strategy for initial detection of bone lesions?

To determine the cost-effectiveness of different imaging modalities for initial detection of multiple myeloma (MM)-defining bone lesions. A Markov model from the health care system perspective for patients with MGUS was used to evaluate the incremental cost-effectiveness of five imaging techniques: skeletal survey (SS), low-dose computed tomography (LDCT), positron emission computed tomography (PETCT), and whole-body magnetic resonance imaging (WBMRI) with and without diffusion (DIFF). Model inputs, including probabilities, utilities, and costs were obtained from comprehensive literature review. Costs were estimated in 2024 U.S. dollars, effectiveness was measured in quality adjusted life years (QALYs), willingness-to-pay (WTP) threshold was set to $100,000/QALY, and timeframe of the simulation was 20years. Model analyses included Monte Carlo microsimulation and probabilistic sensitivity analysis (PSA). The most cost-effective imaging strategy was dependent on the number of patient risk factors for progression from MGUS to myeloma. At a WTP threshold of $100,000, for patients with no risk factors for progression, LDCT amassed the greatest net monetary benefit (NMB) ($1,030,913.57) while incurring the second lowest costs ($44,870.73). For patients with 1 or 2 risk factors for progression, WBMRI + DIFF amassed the greatest NMB (1 risk factor: $802,637.30, 2 risk factors: $664,430.36). WBMRI and PETCT were absolutely dominated in all cases. PSA also found that the most cost-effective strategy was dependent on the WTP threshold. Our model suggests that LDCT and WBMRI + DIFF can be the most cost-effective imaging strategies for the initial diagnosis of MM in patients, depending on the number of risk factors for progression.

Cost-Effectiveness of Hypoglossal Nerve Stimulation for Pediatric Severe Obstructive Sleep Apnea in Down Syndrome Patients.

To examine the cost-effectiveness of hypoglossal nerve stimulation (HGNS) implantation at an early age in simulated pediatric cohorts with Down Syndrome (DS) and severe obstructive sleep apnea (OSA). Cost-utility analysis. Hypothetical cohort. A Markov model simulated 3 pediatric cohorts with DS and OSA beginning at age 4 years until 21 years. Cohorts received HGNS implants in early childhood, late childhood, or adulthood at age 4, 13 (current FDA-approved age), or 18 years, respectively. Input model parameters were obtained from the literature and our institution. Outcomes were measured with an incremental cost-effectiveness ratio (ICER), measured in dollars per quality-adjusted life-year (QALY). Deterministic 1-way sensitivity analyses were conducted to evaluate the effects of parameter uncertainty. Results (total costs; total QALYs) across the time horizon were determined for each cohort: early implantation ($83,300.35; 15.79), late ($48,319.09; 14.98), and adult ($38,721.07; 14.55). ICERs were $48,892.47 per QALY for early vs late implantation, $43,471.15 per QALY for early vs adult implantation, and $30,959.58 per QALY for late vs adult implantation. All ICERs were below a willingness-to-pay threshold of $50,000 per QALY. Varying the discount rate and utility expectedly varied the ICERs and cost-effectiveness. Threshold analysis showed early implantation to be cost-effective for a HGNS implantation cost up to $62,230 compared to late implantation. The current study suggests HGNS is a cost-effective treatment strategy for pediatric patients with DS and severe OSA. Our findings also suggest cost-effectiveness at ages younger than 13, the current age of FDA approval.

A Clinical and Economic Comparison of Cell-Based Versus Recombinant Influenza Vaccines in Adults 18–64 Years in the United States

Background: This analysis compares the cost-effectiveness of a cell-based influenza vaccine to a recombinant influenza vaccine, and each to no vaccination. The analysis is based on United States (US) commercial and societal perspectives. Methods: A Susceptible–Exposed–Infectious–Recovered (SEIR) transmission model of the total US population followed with a cost-effectiveness model for 18–64-year-olds was used to estimate the clinical and economic impact of vaccination over one influenza season (2018–2019). Deterministic and probabilistic sensitivity analyses were conducted. Results: Both enhanced vaccines prevented a substantial number of influenza cases and influenza-related deaths compared to no vaccination. The cell-based vaccine was associated with higher quality-adjusted life years (QALYs) gained compared to the recombinant vaccine or no vaccination. The cell-based vaccine had a 36% lower vaccination cost, amounting to $2.8 billion in cost savings, compared to the recombinant vaccine. The incremental cost-effectiveness ratios (ICERs) for the cell-based vaccine, compared to the recombinant vaccine or no vaccination, were dominant from all payer perspectives, regardless of risk groups. Conclusions: Overall, the cell-based vaccine was cost-saving compared to the recombinant vaccine for subjects aged 18–64 years in the US, achieving comparable health outcomes with a significant reduction in associated costs.

Cost-effectiveness analysis of mindfulness-based cognitive therapy in patients with anxiety disorders in secondary mental health care settings alongside a randomized controlled trial.

Anxiety disorder is one of the most prevalent mental disorders. Mindfulness-based cognitive therapy (MBCT) is effective for treating anxiety disorders. However, no studies have investigated the cost-effectiveness of MBCT for anxiety disorders. We aimed to conduct a cost-effectiveness analysis alongside a randomized controlled trial (RCT) to clarify the cost-effectiveness of MBCT for anxiety disorders. A cost-effectiveness analysis alongside an RCT was conducted for 8 weeks in 40 patients with anxiety disorders at a university hospital. Patients (1) aged 20-75 years; (2) who were diagnosed with panic disorder/agoraphobia or social anxiety disorder based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria; and (3) who provided written consent were analyzed. The participants were allocated randomly (1:1 ratio) to the augmented MBCT group (i.e., MBCT plus treatment as usual [TAU]) or TAU (waitlist control) group. The cost-effectiveness was assessed using the incremental cost-effectiveness ratio (ICER), which is the ratio of the incremental costs divided by the incremental state-trait anxiety inventory- state (STAI-S), state-trait anxiety inventory- trait (STAI-T), and quality-adjusted life years (QALYs). The QALYs were estimated using The Japanese version of EuroQoL five-dimensional 3-level questionnaire. The unit cost data were derived from the government-regulated fees. This study was conducted from a public healthcare insurance perspective. No discount rates were considered. A total of 38 participants with complete data were included in the analysis. The MBCT was JPY 13,885 more than the cost of TAU and was associated with a STAI-S, STAI-T, and QALY increase of 10.13, 12.00, 0.009 respectively. The ICER were JPY 1,371 (USD13) per STAI-S, JPY 1,157 (USD 11) per STAI-T, and JPY 1,566,357 (USD 14,940) per QALY respectively. MBCT had an 77.5% probability of being cost-effective at a willingness to pay threshold in Japan (JPY 5,000,000 per QALY). The results of the four one-way sensitivity analyses supported the robustness of the base-case analysis findings. Augmented MBCT for anxiety disorders is cost-effective compared with TAU post-treatment from a public healthcare insurance perspective. Future studies should include long-term observations, and analysis from a societal perspective.

Cost-effectiveness analysis of genotype-guided optimization of major depression treatment in Qatar.

Pharmacogenetic testing improves the efficacy and safety of antidepressant pharmacotherapy for moderate-severe major depressive disorder by identifying genetic variations that influence medication metabolism, and adjusting treatment regimens accordingly. This study aims to assess the cost-effectiveness of implementing a pharmacogenetic testing approach to guide the prescription of antidepressants. From the public hospital perspective, we developed a two-stage decision tree diagram of a short-term 6-week follow up, and a lifetime Markov model with 3-month cycles. The analysis compared the current standard of care with the alternative strategy of Pharmacogenetic-guided (multi-gene panel) testing in adult patients with moderate-severe major depressive disorder. Clinical outcomes and utilities were obtained from published studies, while healthcare costs were locally available. The short-term incremental cost-effectiveness ratio was against treatment response without side effects and without relapse, and against treatment response with/without side effects and without relapse. The long-term incremental cost-effectiveness ratio was against the quality-adjusted life year gained and years of life saved. Adopting the pharmacogenetic-guided therapy for adult patients with moderate-severe major depressive disorder in Qatar resulted in cost savings of Qatari Riyal 2,289 (95% confidence interval, -22,654-26,340) for the health system. In the short term, the pharmacogenetic-guided testing was associated with higher response rates without side effects and without relapse (mean difference 0.10, 95% confidence interval 0.09-0.15) and higher response rates with or without side effects and without relapse (mean difference 0.05, 95% confidence interval 0.04-0.06). For long term, the pharmacogenetic-guided testing resulted in 0.13 years of life saved and 0.06 quality-adjusted life year gained, per person, along with cost savings of Qatari Riyal 46,215 (95% confidence interval-15,744-101,758). The sensitivity analyses confirmed the robustness of the model results. Implementing pharmacogenetic testing to guide antidepressant use was found to improve population health outcomes, while also significantly reducing health system costs.

Фармакоэкономический анализ различных методов лечения акне у детей и подростков

Acne is a widespread dermatological disease affecting children and adolescents that requires the use of innovative approaches to its treatment with the purpose of not only improving the patient's condition but also to minimize the treatment costs. The purpose of this research was to analyze the clinical efficacy, safety and economic feasibility of the use of the cold atmospheric plasma (CAP) in the acne therapy. Materials and methods used: the study included 176 pediatric patients aged 10 to 18 y/o (ME 16 y/o, M:F gender ratio 1:1.2) who were divided into groups depending on the severity of acne as follows: G1 with mild acne, G2 with moderate acne, and randomized into subgroups depending on the treatment methods (TM) as follows: TM1 for monotherapy with a combined external drug containing 0.1% adapalene with 2.5% benzoyl peroxide in the form of a gel, TM2 for CAP monotherapy and TM3 for combined therapy consisting of external therapy with a gel containing 0.1% adapalene with 2.5% benzoyl peroxide and the CAP treatment. The severity of acne was assessed using the acne dermatological index (ADI) and the clinical efficacy was assessed by achieving ADI0, ADI75, and ADI50. Skin moisture and pH were measured in all patients both prior to and immediately after the treatment using the PH98110 pH meter (by Kelilong, China). Adverse events (AE) were assessed during the study. The incremental cost-effectiveness ratio (ICER) was used in the pharmacoeconomic analysis. Results: during treatment in the TM1 subgroups, the full clinical effect (DIA0) was achieved in 88.89% of cases with mild acne and in 61.76% of cases with moderate acne, in the TM2 s/g, the full clinical effect was achieved in 95.24% and 68.57% of cases and in the TM3 s/g in 100% and 88.24% of cases, respectively. After the treatment, the skin pH values in patients of the TM1 s/g, G1 and G2 became lower than the reference values, TM2 and TM3 s/gs of both groups returned to normal. Skin moisture after treatment decreased in the TM1 s/g of both groups, remained the same in the TM2 s/g and the TM3 s/g of G1 and approached to normal in the TM2, TM3 s/gs of G2. AEs (lichenification, erythema and/or burning sensation of the skin) were observed in patients of s/gs TM1 and TM3 and were mild (n=24) or moderate (n=25) in severity. The ICER coefficient for the TM1 v TM3 pairwise comparison was 324,254.55 Russian rubles for G1, 184,060.00 Russian rubles for G2, and for the TM2 v TM3 comparison 25,333.33 Russian rubles for G1, 12,800.00 Russian rubles for G2, which is statistically significant (p=0.001 and p=0.04, respectively) and indicates high economic feasibility of using the TM3. Conclusion: the use of CAP in the treatment of mild to moderate acne is effective, safe and cost-effective as well.

Cost-effective and optimal control analysis for mitigation strategy to chocolate spot disease of faba bean

Faba bean is one of the most important grown plants worldwide for human and animal. Despite its various importance, the productivity of faba bean has been constrained by several biotic and abiotic factors. Many faba bean pathogens have been reported so far, of which the most important yield limiting disease is Chocolate Spot Disease (Botrytis fabae). The dynamics of disease transmission and decision-making processes for intervention programs for disease control are now better understood through the use of mathematical modeling. In this paper a deterministic mathematical model for Chocolate Spot disease (CSD) on faba bean plant with an optimal control model was developed and analyzed to examine the best strategy in controlling CSD. The optimal control model is developed with three control interventions, namely prevention (u1\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$u_{1}$$\\end{document}), quarantine (u2\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$u_{2}$$\\end{document}) and chemical control (u3\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$u_{3}$$\\end{document}). The Pontryagin’€™s maximum principle isused to derive the Hamiltonian, the adjoint variables, the characterization of the controls and the optimality system. A cost-effective approach is chosen from a set of possible integrated strategies using the incremental cost-effectiveness ratio (ICER). The forward-backward sweep iterative approach is used to run numerical simulations. We obtained the Hamiltonian, the adjoint variables, the characterization of the controls and the optimality system. The numerical results demonstrate that each integrated strategy can reduce the diseases within the specified period. However due to limited resources, an integrated strategy prevention and uprooting was found to be a best cost-effective strategy to combat CSD. Therefore, attention should be given for the integrated cost-effective and environmentally eco-friendly strategy by stake holders and policy makers to control CSD and disseminate the integrated intervention to the farmers in order to fight the spread of CSD in the Faba bean population and produce the expected yield from the field.

Real-world clinical and economic outcomes from rapid start antiretroviral therapy in HIV: systematic review and meta-analysis.

We aimed to synthesize clinical and economic outcomes of rapid start versus non-rapid antiretroviral therapy (ART) in people with HIV (PWH) in real-world settings. A search was conducted in PubMed, Embase, Web of Science, and ProQuest from January 2017 to January 2023, supplementing a previous search by Ford et.al, 2018. Observational studies investigating clinical or economic outcomes of rapid start ART versus non-rapid ART in PWH were included. Clinical outcomes were mortality, loss-to-follow-up (LTFU), and viral suppression. Economic outcomes were Incremental cost-effectiveness ratio (ICER) values and per patient per month (PPPM) costs. Meta-analyses using random-effects models were performed for clinical outcomes, while qualitative syntheses were conducted for economic outcomes. The quality of clinical and economic studies was assessed. Sixty-two studies were included. The pooled adjusted risk ratio (aRR) for mortality demonstrated a significant reduction in risk of mortality among participants who received rapid start ART compared to non-rapid ART (0.80, 95%CI, 0.65-0.98). For LTFU at 6 and 12 months, the pooled aRR showed increased LTFU for rapid start ART (1.33, 95%CI, 1.15-1.55 and 1.18, 95%CI, 0.74-1.89 respectively). All cost-effectiveness studies reported cost-saving or cost-effective findings. The PPPM costs of rapid start ART across the first 36 months of treatment were consistently lower than non-rapid ART. Rapid ART is associated with reduced mortality and is cost-effective compared to non-rapid ART in real-world settings. Clinicians and policymakers should consider these findings to facilitate rapid start of ART in PWH. Further research on LTFU in PWH is needed.
