Cost-Effectiveness of Pembrolizumab as First-Line Treatment in Patients with Persistent, Recurrent, or Metastatic Cervical Cancer in the United States.

First-line treatment of persistent, recurrent, or metastatic (advanced) cervical cancer in patients who have a combined positive score (CPS) ≥ 1 with pembrolizumab + chemotherapy versus standard-of-care chemotherapy provides meaningful improvements in overall survival. We conducted a cost-effectiveness analysis from a US payer perspective. A societal perspective scenario was also considered, including productivity gains. The cost-effectiveness of pembrolizumab + chemotherapy versus chemotherapy was assessed using a state-transition model comprising the health states "pre-progression," "post-progression," and "death," with a 1-week cycle length and 50-year time horizon. Patient-level KEYNOTE-826 data informed the efficacy, safety, and health-related quality of life of pembrolizumab + chemotherapy versus chemotherapy at first-line and subsequent treatments. Real-world data were sought to cost subsequent treatments according to US clinical practice. Transition probabilities were derived from parametric survival models fit to time-to-progression, progression-free survival, and post-progression survival patient-level KEYNOTE-826 data. Sensitivity analyses explored the impact on outcomes from variables such as bevacizumab use. According to the state-transition model, pembrolizumab + chemotherapy extended mean life expectancy versus chemotherapy from 1.8 to 6.7 life-years. The mean gain of 4.9 life-years/patient was mostly caused by pembrolizumab delaying progression. Total discounted quality-adjusted life-years (QALY) were 5.0 and 1.3 per patient for pembrolizumab + chemotherapy and chemotherapy, respectively (mean gain: 3.7 QALY/patient). Pembrolizumab + chemotherapy had comparable safety outcomes to chemotherapy alone. Total costs incurred were US $320,247 (pembrolizumab + chemotherapy) versus US $105,446 (chemotherapy; mean incremental costs: US $214,801/patient). The incremental cost-effectiveness ratio of pembrolizumab + chemotherapy versus chemotherapy was US $58,446/QALY. Sensitivity analyses showed results were insensitive to bevacizumab use. Including productivity gains led to an incremental cost-effectiveness ratio of US $58,385 per QALY. Our model-based analysis suggests that first-line treatment of pembrolizumab + chemotherapy in advanced cervical cancer with a CPS ≥ 1 offers a substantial clinical benefit over standard-of-care chemotherapy alone and is cost-effective at a willingness-to-pay threshold of US $150,000. The approximate doubling of life-years and QALYs associated with pembrolizumab + chemotherapy represents a step improvement in the treatment of advanced cervical cancer.

Health care resource utilization and costs across stages of amyotrophic lateral sclerosis in the United States.

People living with ALS (plwALS) experience motor control loss, speech/swallowing difficulties, respiratory insufficiency, and early death. Advancing disease stage is typically associated with a greater burden on the health care system, and delays in diagnosis can result in substantial health care resource utilization (HCRU). To estimate HCRU and cost burden of plwALS across disease stages from a US payer perspective we assessed HCRU and costs in early-, mid-, and late-stage ALS. Using insurance claims data from the IBM MarketScan Databases between January 2013 and December 2019, we identified plwALS as having at least 2 claims at least 27 days apart with an ALS International Classification of Diseases, Ninth or Tenth Revision diagnosis code (335.20/G12.21) or at least 1 ALS diagnosis code and prescription filled for riluzole/edaravone. Eligible plwALS were aged at least 18 years and had at least 12 months of enrollment data before and at least 6 months after the index date (date diagnosis criteria met). plwALS were grouped into disease stages using an ALS severity-based staging algorithm developed using ALS symptom and staging survey data from 142 neurologists reporting on 880 plwALS. The starting date of each severity stage was defined as the first date of an ALS symptom within the early-, mid-, and late-stage categories, respectively. The ending date for a severity stage was defined as the day before the first date of an ALS symptom from a more severe category. plwALS could transition to more severe stages, with reverse transition of severity excluded. Mixed regression modeling was used to assess differences in HCRU and costs per person-year between severity stages, adjusted for age and sex. 2,273 plwALS were included in the total ALS study sample, with 1,215 early-stage, 1,511 midstage, and 1,186 late-stage plwALS. 90% of early-stage plwALS had ALS symptoms before diagnosis, and 27% of late-stage plwALS had a late-stage symptom before diagnosis. In the evaluation period, later-stage ALS groups had more overall hospital admissions (early = 0.15, middle = 0.23, and late = 0.74; P < 0.01), outpatient visits/service (early = 26.81, middle = 32.78, and late = 48.54; P < 0.01), emergency department visits (early = 0.46, middle = 0.69, and late = 1.03; P < 0.01), and total prescription count (early = 9.23, middle = 11.37, and late = 12.72; P < 0.01) over 12 months. Annualized costs increased as ALS progressed (early = $31,411, middle = $51,481, and late = $121,903; P < 0.01), which was primarily driven by higher frequency of and cost per hospital admission. HCRU and costs increased with ALS progression, with diagnosis frequently occurring even after experiencing late-stage symptoms. These findings highlight the potential value of delaying progression into a more resource-intensive stage by diagnosing and adequately treating plwALS earlier in the disease course.

Cost of integrated immunization campaigns in Nigeria and Sierra Leone: bottom-up costing studies

BackgroundTo improve the efficient use of scarce resources, low- and middle-income countries and development partners are increasingly encouraged to deliver multiple vaccines and other interventions in a single integrated campaign. However, little is known regarding the cost of delivering vaccines through integrated campaigns, and the extent to which efficiencies are achieved. To fill this evidence gap, we estimated the cost of integrated immunization campaigns in Nigeria and Sierra Leone, and the potential savings from integration.MethodsWe conducted a retrospective ingredients-based costing study from a payer perspective of a campaign held in 2019 in Sierra Leone with measles-rubella vaccine and oral polio vaccine, during which nutrition supplements were also offered in part of the country, and yellow fever campaigns held in three states in Nigeria in 2019 and 2020, where in one state (Anambra) meningococcal A vaccines were co-delivered. We collected data from 108 health facilities, all relevant administrative levels, and implementing partners. We estimated the full financial and economic cost of each campaign, the average unit cost of delivery, as well as the cost by activity and resource type. We also estimated the cost savings from integration in Anambra state by modelling out the cost of the alternative of two standalone campaigns.ResultsThe average financial delivery cost was $0.34 per dose in Sierra Leone, and the economic cost was $0.73 per dose. In Nigeria, the financial cost per dose was $0.29–$0.35 across the three states, and the economic cost per dose was $0.62–$0.85. Facilities and wards delivering more doses achieved a lower financial and economic unit cost of delivery, demonstrating evidence of economies of scale. We estimated that Anambra may have saved at least $1,204,133 in financial resources by integrating yellow fever and meningitis A vaccine delivery, amounting to $0.17 per dose delivered. When including opportunity costs, the economic cost saving was estimated at $0.34 per dose delivered.ConclusionsThe study offers evidence on what it costs to deliver integrated campaigns, and shows that integrated delivery is likely to result in significant cost savings. Where high delivery volumes can be achieved, integrated campaigns can benefit from economies of scale. The findings can be used to inform planning and budgeting for immunization campaigns in low- and middle-income countries.

Informing HPV vaccine pricing for government-funded vaccination in mainland China: a modelling study

The high price of HPV vaccines remains a significant barrier to vaccine accessibility in China, hindering the country's efforts toward cervical cancer elimination and exacerbating health inequity. We aimed to inform HPV vaccine price negotiations by identifying threshold prices that ensure that a government-funded HPV vaccination programme is cost-effective or cost-saving. We used a previously validated transmission model to estimate the health and economic impact of HPV vaccination over a 100-year time horizon from a healthcare payer perspective. Threshold analysis was conducted considering different settings (national, rural, and urban), cervical cancer screening scenarios (cytology-based or HPV DNA-based, with different paces of scale-up), vaccine types (four types available in China), vaccine schedules (two-dose or one-dose), mode of vaccination (routine vaccination with or without later switching to high-valency vaccines), willingness-to-pay thresholds, and decision-making criteria (cost-effective or cost-saving). Furthermore, we examined the budget impact of introducing nationwide vaccination at the identified threshold prices. Using the current market price, national routine HPV vaccination with any currently available vaccine is unlikely cost-effective. Under a two-dose schedule, the prices of the four available HPV vaccine types cannot exceed $26-$36 per dose (44.1%-80.2% reduction from current market prices) depending on vaccine type to ensure the cost-effectiveness of the national programme. Adopting vaccination at threshold prices would require an annual increase of 72.18%-96.95% of the total annual National Immunization Programme (NIP) budget in China. A cost-saving routine vaccination programme requires vaccine prices of $5-$10 per dose (depending on vaccine type), producing a 21.38%-34.23% increase in the annual NIP budget. Adding the second dose is unlikely to be cost-effective compared to a one-dose schedule, with the threshold price approaching or even falling below zero. Rural pilot vaccination programmes require lower threshold prices compared with a national programme. Our study could inform vaccine price negotiation and thus facilitate nationwide scale-up of current HPV vaccination pilot programmes in China. The evidence may potentially be valuable to other countries facing HPV introduction barriers due to high costs. This approach may also be adapted for other contexts that involve the introduction of a pricy vaccine. CAMS Innovation Fund for Medical Sciences (CIFMS); Bill & Melinda Gates Foundation.

Risk-stratified hepatocellular carcinoma screening according to the degree of obesity and progression to cirrhosis for diabetic patients with metabolic dysfunction-associated steatotic liver disease (MASLD) in Japan: a cost-effectiveness study.

To evaluate the cost-effectiveness of risk-stratified hepatocellular carcinoma (HCC) screening in diabetic patients with metabolic dysfunction-associated steatotic liver disease (MASLD). A state-transition model from a healthcare payer perspective on a lifetime horizon. Japan. A hypothetical cohort of 50-year-old diabetic patients with MASLD risk-stratified according to degree of obesity and progression to cirrhosis. Metabolic dysfunction-associated steatotic liver (MASL), metabolic dysfunction-associated steatohepatitis (MASH) and MASH cirrhosis are progressive manifestations of this specific type of liver disease. Abdominal ultrasound (US), US with alpha-fetoprotein (AFP), US with AFP and lectin-reactive alpha-fetoprotein (AFP-L3), CT, extracellular contrast-media-enhanced MRI (ECCM-MRI), gadoxetic acid-enhanced MRI (EOB-MRI) and no screening. Costs, quality-adjusted life-years (QALYs), incremental cost-effectiveness ratios (ICERs), early-stage HCC cases, advanced-stage HCC cases and HCC-related deaths. EOB-MRI is the most cost-effective screening method for non-obese diabetic patients with MASH cirrhosis and for obese diabetic patients with MASH and MASH cirrhosis. Cost-effectiveness was sensitive to HCC incidence in non-obese diabetic patients with MASH cirrhosis and obese diabetic patients with MASH, and the adherence rate of HCC screening in obese diabetic patients with MASH. When the semiannual HCC incidence was between 0.008 and 0.0138 in non-obese diabetic patients with MASH cirrhosis, US with AFP was more cost-effective than EOB-MRI. Cost-effectiveness acceptability curves showed that EOB-MRI was 50.7%, 96.0% and 99.9% cost-effective in obese diabetic patients with MASH and non-obese diabetic patients with MASH cirrhosis, and obese diabetic patients with MASH cirrhosis at a willingness-to-pay level of $50 000 per QALY gained. Compared with no screening in 100 000 non-obese diabetic patients with MASH cirrhosis and obese diabetic patients with MASH cirrhosis, EOB-MRI reduced total costs by US$69 million and by US$142 million, increased lifetime effectiveness by 12 546 QALYs and by 15 815 QALYs, detected 17 873 and 21 014 early-stage HCC cases, and averted 2068 and 2471 HCC-related deaths, respectively. Of all HCC screening methods for diabetic patients with MASH cirrhosis, EOB-MRI yields the greatest cost-saving with the highest QALYs, detects the greatest number of early-stage HCC cases and averts the greatest number of advanced-stage HCC cases and HCC-related deaths. The findings provide important insights for the precise implementation of risk-stratified HCC surveillance to reduce morbidity and mortality and improve the quality of life in diabetic patients with MASLD.

Cost-effectiveness analysis of atezolizumab plus bevacizumab and chemotherapy for the treatment of metastatic, persistent, or recurrent cervical cancer (BEATcc)

ABSTRACT Background The addition of atezolizumab to bevacizumab plus platinum regimen has demonstrated notable improvements in treating metastatic, persistent, or recurrent cervical cancer, but its cost-effectiveness requires further investigation. From a US payer perspective, we aimed to evaluate the cost-effectiveness of atezolizumab plus bevacizumab and chemotherapy vs. standard chemotherapy as a first-line treatment for metastatic, persistent, or recurrent cervical cancer. Methods A partitioned survival model based on the data from the BEATcc trial was used to calculate the incremental cost-effectiveness ratio (ICER), using cost and health utility information obtained from literature and publicly accessible databases. One-way and probabilistic sensitivity analyses were performed to evaluate the model’s responsiveness to variations in parameters. Results The addition of atezolizumab resulted in an additional 0.839 quality-adjusted life years (QALY) at an additional cost of $458,237, leading to an ICER of $545,943/QALY. One-way sensitivity analysis indicated that the cost of atezolizumab had the greatest impact on the ICER, followed by the utility value of progression-free survival (PFS) and follow-up costs. Probabilistic sensitivity analysis showed a 0% cost-effectiveness probability at the current willingness-to-pay (WTP) threshold of $150,000 per QALY. Conclusion Adding atezolizumab to chemotherapy is cost-prohibitive in the US and may not be cost-effective for patients.

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.

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-Utility Analysis of Low-Dose Pioglitazone in a Population With Prediabetes and a History of Stroke or Transient Ischemic Attack.

Pioglitazone significantly reduces the risk of stroke in people with diabetes, and in those with prediabetes, it markedly reduces the risk of stroke/myocardial infarction and new-onset diabetes. Low-dose pioglitazone provides most of the clinical benefits of high-dose pioglitazone, with fewer adverse effects. We report an economic evaluation of the cost-effectiveness of low-dose pioglitazone versus placebo from a Canadian public payer perspective in 2023 Canadian dollars. A Markov model was developed at a lifetime horizon with an annual cycle length and 5 health states (event-free, myocardial infarction, stroke, new-onset diabetes, and death). Transition probabilities were extracted from the IRIS (Insulin Resistance Intervention in Stroke) trial. Health state costs and utilities were based on public sources. Annual discount rates of 1.5% were applied in the reference-case analysis. Probabilistic analyses were conducted to deal with parameter uncertainty through 5000 simulations. The costs were estimated as $24 887 (interquartile range [IQR], $14 632-$41507) for low-dose pioglitazone and $57 301 (IQR, $48 730-$67368) for placebo, resulting in a cost saving of -$30 287 (IQR, -$43 374 to -$14 587) in favor of low-dose pioglitazone. Quality-adjusted life years were estimated as 25.99 (IQR, 24.56-26.81) for the low-dose pioglitazone and 19.44 (IQR, 18.68-20.13) for placebo, resulting in a difference of 6.37 (IQR, 5.07-7.36) in favor of low-dose pioglitazone. Consistent findings were observed from scenario analyses and 1-way probability sensitivity analyses. Holding across a wide range of values in modeling parameters, low-dose pioglitazone is found as the dominant strategy versus a placebo.

Cost-effectiveness analysis of denosumab versus alendronate for improving bone mineral density in renal transplant recipients: a comparative study

BackgroundDenosumab and alendronate had a positive impact on bone mineral density (BMD) preservation after kidney transplantation. However, the cost-effectiveness of these agents in the context of kidney transplantation remains largely unexplored. We have conducted a cost-effectiveness analysis to compare the cost and the clinical outcomes of adding subcutaneous (SC) 60 mg denosumab every 6 months vs. oral weekly 70 mg Alendronate, to the standard care therapy (vitamin D and calcium) in renal transplant recipients (RTRs). The impact of both drugs on BMD t-score improvement and fracture prevention was investigated. A decision-analysis model from a health care payer perspective was applied.ResultsThe cost-effectiveness analysis has shown that alendronate add-on to the standard therapy was the most cost-effective regimen, in terms of BMD improvement and fracture prevention with an incremental cost-effectiveness ratio (ICER) of $154/patient/year. The one-way sensitivity analyses have delineated the change in cost-effectiveness when alendronate retail unit price was increased by 25% and 50%, or when denosumab retail unit price was decreased by 25% and 50%. The model was sensitive to the uncertainties (95% confidence interval) in the probabilities of fracture prevention and the probabilities of attaining the desired outcome.ConclusionThe model suggests that oral once weekly alendronate add-on regimen to standard therapy seems to be substantially more cost effective than twice yearly SC denosumab in terms of BMD improvement and fracture prevention in RTRs. Longer time horizon models with longer follow-up periods for fracture risks and adverse events are warranted to validate these data.

Economic burden of short-acting beta-2 agonist (SABA) overuse among asthma patients in Türkiye: a cost analysis with respect to the updated GINA treatment recommendations.

This cost of illness study aimed to determine economic burden of short-acting β2-agonist (SABA) overuse in Türkiye from payer perspective with respect to the updated GINA 2022 treatment recommendations. A total of 3,034,879 asthma patients comprised the study population, via estimations extrapolated from the Türkiye arm of the global SABINA III study. The economic burden (costs related to the drug use and severe exacerbations) was compared in subgroups of overall (≥ 0 canisters/year) vs. GINA-recommended (0-2 canisters/year, hypothetical population) SABA use and in subgroups of appropriate use (0-2 canisters/year, real population) vs. overuse (≥ 3 canisters/year) of SABA with extrapolation of SABINA Türkiye data to the Türkiye asthma population. Recommended SABA use was predicted to prevent 127,505 of 157,512 severe exacerbations per year in mild asthma patients and 2,668,916 of 3,262,800 severe exacerbations per year in moderate-severe asthma patients. Annual cost burden of not applying recommended SABA use (overall [≥ 0 canisters/year] vs. GINA-recommended [0-2 canisters/year] SABA use) in mild asthma and moderate-severe asthma patients was calculated to be €20.43 million and €427.65 million in terms of severe exacerbations, and to be €829,352 and €7.20 million in terms of drug costs, respectively. The total annual economic burden arising from not applying recommended SABA use was estimated to be €456.11 million. Appropriate use (0-2 canisters/year) vs. overuse (≥ 3 canisters/year) of SABA was associated with decreased frequency of severe exacerbations per year in mild asthma (from 129,878 to 27,634) and moderate-severe asthma (from 2,834,611 to 428,189) patients. SABA overuse in mild and moderate-severe asthma patients was estimated to yield an additional annual cost of €16.38 million and €385.59 million, respectively in terms of severe exacerbations, and a total €11.30 million additional drug cost. The overall annual economic burden arising from SABA overuse was estimated to be €413.27 million. The estimated annual total economic burden arising from not applying recommended SABA use (€456.11 million) and SABA overuse (€413.27 million) with respect to the updated GINA 2022 treatment recommendations indicates the substantial cost burden of SABA overuse to the Turkish National Health System, corresponding up to 26% of the total direct cost of asthma reported in our country.

Cost-utility of nelarabine for the first-line treatment of newly diagnosed pediatric T-cell acute lymphoblastic leukemia in Canada.

The Children's Oncology Group (COG)-AALL0434 trial investigated the addition of nelarabine to the augmented Berlin-Frankfurt-Münster (aBFM) protocol in patients (1.0-30.99years) with newly diagnosed T-cell acute lymphoblastic leukemia (T-ALL). Despite demonstrating superior outcomes, nelarabine is not currently funded by many health systems, in part due to a lack of cost-effectiveness data. We estimated the cost-utility of nelarabine for this indication from a Canadian public healthcare payer perspective. We developed a microsimulation model that followed hypothetical patients with newly diagnosed T-ALL from post-induction therapy to death. Three health states were modeled: relapse-free, post-relapse, and death. Efficacy was estimated using AALL0434 and retrospective data from Ontario, Canada. Costs were obtained from Canadian sources. Utility estimates and long-term mortality risks were sourced from literature. Total healthcare costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) were reported. Probabilistic and scenario analyses were conducted. Incorporating nelarabine in the aBFM protocol increased costs by $51,670 Canadian dollars per patient, but resulted in 1.97 more QALYs and an ICER of $26,184/QALY. Most of the identified cost and benefit were accrued within the AALL0434 trial period (first 11years post diagnosis) and while patients were in the relapse-free health state. Across multiple scenarios, the ICER was stable under an assumed $50,000/QALY threshold. Incorporating nelarabine into aBFM was cost-effective across different scenarios and assumptions. These results support its funding by public and private payers.

The cost of COVID-19 vaccine delivery in Bangladesh

ABSTRACT COVID-19 vaccination has been instrumental in fighting the pandemic, but evidence on the actual costs associated with delivering these vaccines in resource-constrained settings has been limited. We estimated the cost of delivering COVID-19 vaccines in Bangladesh through five delivery strategies in 2021 and 2022, including Ministry of Health (MOH) hospitals, non-MOH government hospitals, outreach at Expanded Program on Immunization (EPI) centers, mass campaigns, and schools. This was a bottom-up costing study, estimating costs from a payer and beneficiary perspective. We also mapped the funding flows for COVID-19 vaccination activities and analyzed programmatic and financial challenges. The economic cost incurred by the health system to deliver COVID-19 vaccines was $1.05 per dose, excluding vaccine costs. This was made up of a financial cost of $0.29 per dose and an opportunity cost of $0.75 per dose. School-based delivery incurred the lowest financial cost of $0.27, while outreach at EPI centers incurred the highest at $0.44 per dose. The low financial cost per dose is attributed to the high daily volumes delivered at sampled sites, minimal additional resources provided to sites to implement the COVID-19 vaccination program, and a reliance on the existing workforce. Beneficiaries spent an average of $1.63 to receive a single dose of COVID-19 vaccination at fixed sites, with transport representing the largest cost driver ($0.75 per dose). The economic cost to receive one dose of the COVID-19 vaccine was $4.78. Findings can support the Government of Bangladesh to make efficient and equitable resource allocation decisions for vaccination programs.

Cost-effectiveness of prophylactic ramosetron in the prevention of postoperative nausea and vomiting.

This study was conducted to assess the cost-effectiveness of prophylactic use of ramosetron compared to no antiemetic medications for the prevention of postoperative nausea and vomiting (PONV) from the healthcare payer and societal perspectives in South Korea. A decision analytic model was constructed to assess the cost-effectiveness of prophylactic ramosetron use versus no antiemetic therapy at 24-hour and 48-hour periods post-surgery over a 5-day duration. The model was populated using costs and utility parameters from published studies as well as from surveys of an expert panel of physicians using structured questionnaires. The cost parameters included the costs of drugs, treatment, patient time, productivity loss, and transportation. Effectiveness was measured using quality adjusted life years (QALYs). The study outcome was the incremental cost-effectiveness ratio (ICER). The parameter uncertainties were addressed using deterministic and probabilistic scenario analyses. The base-case analysis showed that, on average, patients treated with prophylactic ramosetron had lower costs from both the healthcare payer (US$16.88 vs US$17.33) and societal (US$16.89 vs US$18.72) perspectives and higher QALYs (0.0121 vs 0.0114) over the 5-day study duration compared to patients without any antiemetic medications. Deterministic and probabilistic sensitivity analyses were conducted to examine the robustness of results for the parameters included in the model. The acceptability curve probability showed that treating patients with ramosetron compared to no antiemetic medications was more than 99% cost-effective at a willingness-to pay threshold of US$5,000/QALY from both payer and societal perspectives. The results demonstrated that prophylactic use of ramosetron compared to no antiemetic therapy is highly cost-effective to prevent PONV for patients undergoing surgery from both healthcare payer and societal perspectives. The cost effectiveness is the result of the decrease in the incidence of PONV and the direct treatment costs of severe PONV with improved patient quality of life.

Cost-effectiveness of universal esophageal cancer screening for newly diagnosed oral cancer patients.

Oral and esophageal cancers are globally prevalent, especially in East Asia. Over half of head and neck cancer patients developing second primary esophageal cancer (SPEC) were initially diagnosed with oral cavity cancer (OCC). This study assessed the cost-effectiveness of universal endoscopic screening for early SPEC prevention in newly diagnosed OCC patients at different stages. This study employed Markov cohort models to evaluate the cost-effectiveness of endoscopic SPEC screening post-OCC diagnosis (stages 0 to IV) between screened and non-screened groups. Four surveillance frequencies were assessed: (i) one time, (ii) annual for 3years, (iii) annual for 10years, and (iv) annual for life. A hypothetical cohort of 100000 cases across stages was compared for costs and quality-adjusted life-years (QALYs), discounted annually at 3%. All four screening strategies were beneficial for all OCC stages, especially for early-stage patients, resulting in higher QALYs. Lifetime/annual screening from the payer's perspective proved most favorable, with incremental QALYs of 1.23 at stage 0 and 0.06 at stage IV. Incremental costs for this strategy ranged from NTD 121331 (USD 4044) at stage 0 to NTD 13032 (USD 434) at stage IV. Both incremental costs and incremental cost-effectiveness ratio (ICER) values indicated cost savings from a societal perspective. The ICER values ranged from NTD -626440 (USD -20881) at stage 0 and NTD -475021 (USD -15834) at stage IV. Overall, our study provided cost-effectiveness evidences to understanding the cost-effectiveness of endoscopic screening in OCC patients, particularly emphasizing the benefits of early and consistent screening.

Economic burden of vulvar, vaginal, anal, penile and head &amp;amp; neck cancers in Bulgaria

A retrospective, cost-of-illness study aimed at identifying direct healthcare costs of vulvar, vaginal, anal, penile, and H&amp;N cancers in Bulgaria from the payer perspective and calculating indirect costs and the associated years of life lost was carried out. Costs’ data were obtained from the National Health Insurance Fund from January 2018 to December 2020. Years of life lost were calculated based on the country and gender-specific life expectancy. The human capital approach was used to evaluate the indirect costs. The total treatment costs for 3623 patients were EUR 10,875,771 (2018), EUR 11,922,521 (2019) and EUR 12,329,463 (2020). The costs associated with radiotherapy and drug acquisition and administration accounted for the majority (75–78%) of total healthcare costs. A cumulative loss of approximately 33,299 life years occurred between 2018 and 2020. The costs of productivity losses were estimated at EUR 14,113,265.

Cost-Effectiveness of Teduglutide for Pediatric Patients with Short Bowel Syndrome in Japan, Including Caregiver Burden.

Short bowel syndrome (SBS) is associated with a significant mental and physical burden for patients and caregivers. Standard of care (SOC) for SBS includes parenteral support (PS) to optimize intestinal function. Teduglutide, a recombinant human glucagon-like peptide2 analogue, reduces the need for PS in patients with SBS. In this study, we assessed the cost-effectiveness of teduglutide in pediatric patients with SBS from multiple perspectives, considering the caregiver's burden. A Markov model was used to evaluate cost (Japanese yen, JPY) and effectiveness (quality-adjusted life years, QALYs) of teduglutide compared with SOC for pediatric patients with SBS in Japan. We conducted a base-case analysis and selected sensitivity and scenario analyses from three perspectives: (1) the public healthcare payer, (2) the public healthcare and long-term care payer, and (3) society. In the base-case analysis, the incremental cost-effectiveness ratio (ICER) was 9,533,412 JPY per QALY from the public healthcare payer perspective, 6,335,980 JPY per QALY from the public healthcare and long-term care payer perspective, and 3,510,371 JPY per QALY from the societal perspective. The probability that cost-effectiveness of teduglutide is favorable from a societal perspective was 59.3%. In all scenario analyses, consistent with the base-case analysis, ICERs for teduglutide compared with SOC were different depending on whether caregiver utility and productivity loss were considered. Incorporating the caregiver's burden in the cost-effectiveness analysis of teduglutide for pediatric patients with SBS provided a more comprehensive assessment of the value of teduglutide for patients, their families, and society. This approach enhances our understanding of the overall value of a treatment, especially for diseases with significant caregiver burden.

Introduction of a hexavalent vaccine containing acellular pertussis into the national immunization program for infants in Peru: a cost-consequence analysis of vaccination coverage

BackgroundInfant vaccination coverage rates in Peru have declined in recent years, exacerbated by the COVID-19 pandemic. Introduction of the fully-liquid diphtheria, tetanus, and acellular pertussis (DTaP)-inactivated polio vaccine (IPV)-hepatitis B (HB)-Haemophilus influenzae type B (Hib) hexavalent vaccine (DTaP-IPV-HB-Hib) in Peru’s infant National Immunization Program may help improve coverage. We evaluated costs and healthcare outcomes, including coverage, of switching from a pentavalent vaccine containing whole-cell pertussis component (DTwP-HB-Hib) plus IPV/oral polio vaccine (IPV/OPV) to the hexavalent vaccine for the primary vaccination scheme (2, 4 and 6 months).MethodsThe analysis was performed over a 5-year period on a cohort of children born in Peru in 2020 (N = 494,595). Four scenarios were considered: the pentavalent plus IPV/OPV scheme (S1); replacing the pentavalent plus IPV/OPV scheme with the hexavalent scheme (S2); expanded delivery of the pentavalent plus IPV/OPV scheme (S3); expanded delivery of the hexavalent scheme (S4). Vaccine coverage and incidence of adverse reactions (ARs) were estimated using Monte Carlo simulations and previous estimates from the literature. Cases of vaccine-preventable diseases were estimated using a Markov model. Logistical and healthcare costs associated with these outcomes were estimated. Impact of key variables (including coverage rates, incidence of ARs and vaccine prices) on costs was evaluated in sensitivity analyses.ResultsThe overall cost from a public health payer perspective associated with the pentavalent plus IPV/OPV vaccine scheme (S1) was estimated at $56,719,350, increasing to $61,324,263 (+ 8.1%), $59,121,545 (+ 4.2%) and $64,872,734 (+ 14.4%) in scenarios S2, S3 and S4, respectively. Compared with the status quo (S1), coverage rates were estimated to increase by 3.1% points with expanded delivery alone, and by 9.4 and 14.3% points, if the hexavalent vaccine is deployed (S2 and S4, respectively). In both scenarios with the hexavalent vaccine (S2 and S4), pertussis cases would also be 5.7% and 8.7% lower, and AR rates would decrease by 32%. The cost per protected child would be reduced when the hexavalent vaccine scheme. Incidence of ARs was an important driver of cost variability in the sensitivity analysis.ConclusionsImplementation of the hexavalent vaccine in Peru’s National Immunization Program has a positive public health cost consequence.

Cost Effectiveness of Sequencing Vedolizumab as First-Line Biologic in Ulcerative Colitis and Crohn's Disease in Canada: An Analysis Using Real-World Evidence from the EVOLVE Study.

Vedolizumab is a gut-selective anti-lymphocyte trafficking biologic indicated for the treatment of adult patients with moderately to severely active ulcerative colitis (UC) and Crohn's disease (CD) in Canada. The objective of this study was to evaluate the cost effectiveness of treatment sequencing for UC and CD from a public healthcare payer perspective, leveraging new real-world evidence from the literature and the EVOLVE study, a retrospective chart review. Using separate decision tree/Markov models to assess cost effectiveness for UC and CD, two sequencing approaches were estimated for adult patients (≥ 18years) diagnosed with UC or CD who were biologic-naïve: vedolizumab as first-line biologic followed by anti-tumor necrosis factor (TNF)-α versus first-line anti-TNFα followed by vedolizumab. Treatment effectiveness (response and remission), surgery rates, dose escalation and regain of response and safety inputs were estimated from EVOLVE, a retrospective chart review of real-world data, and evidence synthesis from the literature, whereas costs and utilities were estimated from health technology assessment reports, clinical trials, and the literature. Biosimilar costs were used for anti-TNFα. Both models simulated a 5-year time horizon and discounted costs and outcomes at 1.5%. Probabilistic base-case analyses (n=10,000) reported total costs (2023 Canadian dollars) and quality-adjusted life-years (QALYs). Several scenario analyses were conducted to explore robustness of results. In UC, vedolizumab as a first-line biologic followed by anti-TNFα resulted in an incremental gain of 0.09 QALYs (2.46 vs. 2.55) and saved $7179 ($134,028 vs. $126,848), making this a dominant strategy compared with first-line anti-TNFα followed by vedolizumab. In CD, use of vedolizumab as a first-line biologic resulted in an incremental gain of 0.04 QALYs (3.35 vs. 3.39) at an incremental cost of $50,631 ($89,850 vs. $140,381) versus first-line anti-TNFα followed by vedolizumab (incremental cost-effectiveness ratio of $1,265,775 per QALY). Based on this analysis, sequencing vedolizumab as a first-line biologic prior to anti-TNFα in UC and CD provided additional clinical benefit to patients. In UC, vedolizumab as a first-line biologic also saved healthcare system costs compared with anti-TNFα, whereas in CD, vedolizumab provided incremental benefit at an incremental cost, which was not considered cost effective at a threshold of $50,000/QALY.

Cost-effectiveness of nonavalent vs bivalent HPV vaccine in Polish setting.

Human papillomavirus (HPV) is a prevalent sexually transmitted infection with significant implications for public health. In Poland, a nationwide vaccination program offers a choice between the 9-valent (9v) and 2-valent (2v) HPV vaccines. We aimed to assess the cost-effectiveness of the 9v vs 2v vaccine from the public payer perspective in Poland. A cost-effectiveness analysis was conducted to compare the public health and economic benefits of using 9v vs 2v vaccine in Poland over 100-year horizon using a previously published deterministic dynamic transmission model. A target population of girls and boys aged 12-13 years was considered. The model was populated with local epidemiological inputs, utilities, and costs, including vaccine and administration costs, as well as costs related to medical procedures for HPV-related diseases. The 9v vaccine reduced the prevalence of HPV infections and HPV-related diseases substantially more than 2v vaccine when both are compared to no vaccination strategy. The total discounted cost savings of using the 9v vaccine instead of 2v, excluding the vaccine costs, amounted to EUR 66 million. The incremental cost-effectiveness ratio amounted to 8094 EUR per quality-adjusted life year, much below the official cost-effectiveness threshold in Poland set up at the three times the annual gross domestic product per capita. 9v cost-effectiveness ratio remained unchanged when shorter time-horizons of 20, 40, 60, or 80 years were considered. Using 9v HPV vaccine in Poland is highly cost-effective compared to the 2v vaccine.
