Abstract Background Herpes zoster (HZ) develops in up to 50% of unvaccinated individuals who live to 85 years of age, accounting for more than 1 million cases of HZ annually in the United States. A live attenuated vaccine (LAV) for HZ is U.S. FDA approved for persons 50 years or older, though CDC Advisory Committee on Immunization Practices (ACIP) recommendations are only for persons beginning at age 60 years. LAV efficacy at preventing HZ is ~70% for persons 50–59 years of age, with lower efficacy in older adults, and it is efficacious in preventing post-herpetic neuralgia (PHN) beyond the HZ prevention. The efficacy of LAV after vaccination wanes over time. A new adjuvanted HZ subunit vaccine (SUV), administered as a two-dose series, has greater than 95% efficacy against HZ in persons 50–69 years of age. SUV efficacy remains greater than 90% in persons vaccinated at age 70 years and older, including the subgroup older than 80 years of age. Overall efficacy of SUV against PHN approaches 90%. The waning rate of efficacy after SUV vaccination is unknown. Methods To estimate the relative cost-effectiveness of SUV, LAV and no vaccination (NV) strategies, a Markov model was developed based on published trials and data on vaccine efficacy persistence, quality of life, resource utilization, costs and disease epidemiology. The perspective was U.S. societal, and the cycle length was one year with a lifelong time horizon. SUV efficacy was estimated for the base case to wane at the same rate as LAV, all persons were assumed to receive both doses of SUV, and the cost of SUV included both doses. Results For individuals vaccinated at age 50 years the incremental cost-effectiveness ratio (ICER) for LAV vs. NV was $142,811 per quality-adjusted life-year (QALY); at age 60 years the ICER dropped to $59,482 per QALY. The cost-effectiveness ratio of SUV approached that of LAV when the SUV cost approached $500 for persons vaccinated at age 50 years and when the cost was $400 for those vaccinated at age 60 years. The SUV cost that would result in achieving an ICER target of $100,000 per QALY for SUV vaccination vs. NV at age 50 years was $316; at age 60 years the cost was $638. Conclusion Vaccination at age 60 years with SUV was more cost-effective than LAV when SUV cost was ~$450 or less. Vaccination with SUV at age 50 years appeared to be cost-effective if SUV cost was ~$315 or less. Disclosures All authors: No reported disclosures.

Herpes Zoster is an unpleasant and painful skin condition associated with a risk of developing post-herpetic neuralgia if the pain persists. Herpes Zoster most often occurs in elderly people. This study examines the cost-effectiveness of introducing a vaccine against Herpes Zoster in the Danish health care sector. The cost-effectiveness is examined in a Markov lifetime model framework and populated with Danish data and results from the international literature. From the base case analysis, with an ICER of DKK 261,372 per QALY gained, it seems that an implementation of a vaccine against HZ in the Danish population aged 65 years or more might be cost-effective within generally accepted incremental cost-effectiveness thresholds. Furthermore, an age-specific analysis showed that although the incidence of herpes zoster generally increases with age, targeting the vaccine at persons aged 50-69 years rather than the persons aged 65 years or more, seems to be a more cost-effective strategy from the societal perspective. However, these results are very sensitive to changes in vaccine price, utility values, discount rates, and especially, to the vaccine duration of protection.Published: Online December 2016.

Background: A number of new anticoagulants for stroke prevention in atrial fibrillation (SPAF) have gained regulatory approval or are in late-stage development. We sought to conduct a systematic review of economic models of dabigatran, rivaroxaban and apixaban for SPAF. Methods: We searched the Medline, Embase, National Health Service Economic Evaluation Database and Health Technology Assessment database along with the Tuft’s Registry through October 10, 2012. Included models assessed the cost-effectiveness of dabigatran (150mg, 110mg, sequential), rivaroxaban or apixaban for SPAF using a Markov model or discrete event simulation and were published in English. Results: Eighteen models were identified. All models utilized a lone randomized trial (or an indirect comparison utilizing a single study for any given direct comparison), and these trials were clinically and methodologically heterogeneous. Dabigatran 150mg was assessed in 9 of models, dabigatran 110mg in 8, sequential dabigatran in 9, rivaroxaban in 4 and apixaban in 4. Adjusted-dose warfarin (either trial-like, real-world prescribing or genotype-dosed) was a potential first-line therapy in 94% of models. Models were conducted from the perspective of the United States (44%), European countries (39%) and Canada (17%). In base-case analyses, patients typically were at moderate-risk of ischemic stroke, initiated anticoagulation between 65 and 73 years of age, and were followed for or near a lifetime. All models reported cost/quality-adjusted life-year (QALY) gained, and while 22% of models reported using a societal perspective, no model included costs of lost productivity. Four models reported an incremental cost-effectiveness ratio (ICER) for a newer anticoagulant (dabigatran 110mg (n=4)/150mg (n=2); rivaroxaban (n=1)) vs. warfarin above commonly reported willingness-to-pay thresholds. ICERs (in 2012US$) vs. warfarin ranged from $3,547-$86,000 for dabigatran 150mg, $20,713-$150,000 for dabigatran 110mg, $4,084-$21,466 for sequentially-dosed dabigatran and $23,065-$57,470 for rivaroxaban. In addition, apixaban was demonstrated to be an economically dominant strategy compared to aspirin and to be dominant or cost-effective ($11,400-$25,059) vs. warfarin. Based on separate indirect treatment comparison meta-analyses, 3 models compared the cost-effectiveness of these new agents and reported conflicting results. Conclusions: Cost-effectiveness models of newer anticoagulants for SPAF have been extensively published. Models have frequently found newer anticoagulants to be cost-effective, but due to the lack of head-to-head trial comparisons and heterogeneity in clinical characteristic of underlying trials and modeling methods, it is currently unclear which of these newer agents is most cost-effective.

Abstract Background Herpes zoster (HZ) develops in up to 50% of unvaccinated individuals, accounting for >1 million cases annually in the United States. A live attenuated HZ vaccine (LAV) is Food and Drug Administration approved for those age 50 years or older, though Advisory Committee on Immunization Practices recommendations are only for those age 60 years or older. LAV efficacy is ~70% for persons 50–59 years of age, with lower efficacy in older adults. A new 2-dose adjuvanted subunit vaccine (SUV) has >95% efficacy in persons 50–69 years of age and remains ~90% efficacious in persons vaccinated at age 70 years. Methods To estimate the relative cost-effectiveness of SUV, LAV, and no vaccination (NoV) strategies, a Markov model was developed based on published data on vaccine efficacy, durability of protection, quality of life, resource utilization, costs, and disease epidemiology. The perspective was US societal, and the cycle length was 1 year with a lifelong time horizon. SUV efficacy was estimated to wane at the same rate as LAV. Outcomes evaluated included lifetime costs, discounted life expectancy, and incremental cost-effectiveness ratios (ICERs). Results For individuals vaccinated at age 50 years, the ICER for LAV vs NoV was $118 535 per quality-adjusted life-year (QALY); at age 60 years, the ICER dropped to $42 712/QALY. SUV was more expensive but had better ICERs than LAV. At age 50, the ICER was $91 156/QALY, and it dropped to $19 300/QALY at age 60. Conclusions Vaccination with SUV was more cost-effective than LAV in all age groups studied. Vaccination with SUV at age 50 years appears cost-effective, with an ICER <$100 000/QALY.

e19399 Background: The recent SOLO1, PRIMA, and PAOLA trials all reported positive efficacy results, making it difficult to determine optimal upfront maintenance therapy for patients with primary, advanced ovarian cancer. We evaluated the cost-effectiveness of the maintenance strategies outlined in these trials for BRCA-positive patients, homologous-recombination deficient patients without a BRCA mutation (HRD-positive), and homologous-recombination proficient (HRD-negative) patients. Methods: Three decision analysis models were developed, one for each mutation status. We evaluated olaparib (SOLO1), olaparib/bevacizumab (PAOLA), bevacizumab alone (PAOLA), and niraparib (PRIMA) maintenance strategies. Base case 1 assessed olaparib vs olaparib/bevacizumab vs bevacizumab vs niraparib vs no maintenance therapy in BRCA-positive patients. Base cases 2 and 3 assessed olaparib/bevacizumab vs bevacizumab vs niraparib vs no maintenance therapy in HRD-positive and HRD-negative patients, respectively. Time horizon was 24 months. Costs, measured in U.S. dollars, were estimated from Medicare claims, wholesale acquisition prices, and previously published sources. Incremental cost-effectiveness ratios (ICERs) were in dollars per progression-free life-year saved (PF-LYS). One-way sensitivity analyses were performed varying drug cost and progression-free survival. Results: Assuming a willingness-to-pay threshold of $100,000/PF-LYS, none of the drug maintenance strategies could be considered cost effective compared with observation. In BRCA-positive patients (base case 1), olaparib monotherapy was the most cost-effective strategy, yielding an ICER of $181,059/PF-LYS. The third-party payer cost per 28-day supply of olaparib would need to be reduced from approximately $17,000 to $9,200 to be considered cost effective compared with observation. In HRD-positive patients (base case 2) and HRD-negative patients (base case 3), bevacizumab monotherapy was the most cost-effective option, with ICERs of $326,491/PF-LYS and $253,937/PF-LYS respectively. Conclusions: At current costs, maintenance therapy for primary ovarian cancer is not cost effective, regardless of mutation status. In BRCA-positive women, lowering the cost of olaparib may make it cost effective compared with observation.

Background: End-stage renal disease has been imposing a heavy economic burden on public health; however, few studies have been performed on the cost-effectiveness of dialysis modalities. We aim to estimate the cost-effectiveness of different dialysis modalities in China. Methods: Cost-effectiveness analyses were performed using Markov models based on published data of hemodialysis (HD) and peritoneal dialysis (PD) modalities in China. Sensitivity analyses were conducted to identify key variables influencing the results. Results: Over a 10-year time horizon, the base-case cost-effectiveness analysis indicated that PD-first absolutely dominated the HD-first option by gaining 0.13 more quality-adjusted life years (QALYs) and costing RMB ¥81,081 less. When using reported mortality of HD and PD from the United States, the PD-first option still dominated HD-first with higher QALYs and lower costs. Sensitivity analyses revealed that the results were more sensitive to the direct cost of HD, utility of HD, utility of PD, direct cost of PD, PD mortality, and HD mortality, while less sensitive to the indirect costs and transition probabilities. The HD utility needed to be at least 0.148 higher than PD utility for HD to be cost-effective. PD was about 72% likely to be considered cost-effective compared with HD, regardless of the willingness-to-pay for QALYs. Conclusion: PD appears to be more cost-effective than HD in China, and the major influential factors on the cost-effectiveness are the direct costs of HD, utility of HD, utility of PD, direct costs of PD, PD mortality, and HD mortality.

When exceptional situations, such as the COVID-19 pandemic, arise and reliable data is not available at decision-making times, estimation using mathematical models can provide a reasonable reckoning for health planning. We present a simplified model (static but with two-time references) for estimating the cost-effectiveness of the COVID-19 vaccine. A simplified model provides a quick assessment of the upper bound of cost-effectiveness, as we illustrate with data from Spain, and allows for easy comparisons between countries. It may also provide useful comparisons among different vaccines at the marketplace, from the perspective of the buyer. From the analysis of this information, key epidemiological figures, and costs of the disease for Spain have been estimated, based on mortality. The fatality rate is robust data that can alternatively be obtained from death registers, funeral homes, cemeteries, and crematoria. Our model estimates the incremental cost-effectiveness ratio (ICER) to be 5132 € (4926–5276) as of 17 February 2021, based on the following assumptions/inputs: An estimated cost of 30 euros per dose (plus transport, storing, and administration), two doses per person, efficacy of 70% and coverage of 70% of the population. Even considering the possibility of some bias, this simplified model provides confirmation that vaccination against COVID-19 is highly cost-effective.

Aim: To evaluate the cost–effectiveness of ribociclib plus fulvestrant versus fulvestrant in hormone receptor-positive/human EGF receptor 2-negative advanced breast cancer. Materials & methods: A three-state Markov model was developed to evaluate the costs and effectiveness over 10 years. Direct costs and utility values were obtained from previously published studies. We calculated incremental cost–effectiveness ratio to evaluate the cost–effectiveness at a willingness-to-pay threshold of $150,000 per additional quality-adjusted life year. Results: The incremental cost–effectiveness ratio was $1,073,526 per quality-adjusted life year of ribociclib plus fulvestrant versus fulvestrant. Conclusions: Ribociclib plus fulvestrant is not cost-effective versus fulvestrant in the treatment of advanced hormone receptor-positive/human EGF receptor 2-negative breast cancer. When ribociclib is at 10% of the full price, ribociclib plus fulvestrant could be cost-effective.

Abstract Objective The aim is to compare the cost-effectiveness of two long-lasting insecticidal nets (LLINs) delivery models (standard vs. new) in universal coverage (UC) campaigns in rural Mozambique. Results The total financial cost of delivering LLINs was US$ 231,237.30 and US$ 174,790.14 in the intervention (302,648 LLINs were delivered) and control districts (219,613 LLINs were delivered), respectively. The average cost-effectiveness ratio (ACER) per LLIN delivered and ACER per household (HH) achieving UC was lower in the intervention districts. The incremental cost-effectiveness ratio (ICER) per LLIN and ICER per HH reaching UC were US$ 0.68 and US$ 2.24, respectively. Both incremental net benefit (for delivered LLIN and for HHs reaching UC) were positive (intervention deemed cost-effective). Overall, the newer delivery model was the more cost-effective intervention. However, the long-term sustainability of either delivery models is far from guaranteed in Mozambique’s current economic context.

Objective To determine threshold cytomegalovirus (CMV) infectious rates and treatment effectiveness to make universal prenatal CMV screening cost-effective. Study Design Decision analysis comparing cost-effectiveness of two strategies for the prevention and treatment of congenital CMV: universal prenatal serum screening and routine, risk-based screening. The base case assumptions were a probability of primary CMV of 1% in seronegative women, hyperimmune globulin (HIG) effectiveness of 0%, and behavioral intervention effectiveness of 85%. Screen-positive women received monthly HIG and screen-negative women received behavioral counseling to decrease CMV seroconversion. The primary outcome was the cost per maternal quality-adjusted life year (QALY) gained with a willingness to pay of $100,000 per QALY. Results In the base case, universal screening is cost-effective, costing $84,773 per maternal QALY gained. In sensitivity analyses, universal screening is cost-effective only at a primary CMV incidence of more than 0.89% and behavioral intervention effectiveness of more than 75%. If HIG is 30% effective, primary CMV incidence can be 0.82% for universal screening to be cost-effective. Conclusion The cost-effectiveness of universal maternal screening for CMV is highly dependent on the incidence of primary CMV in pregnancy. If efficacious, HIG and behavioral counseling allow universal screening to be cost-effective at lower primary CMV rates.

The number of typhoid fever patient in Indonesia is still high. Typhoid fever can be treated by antibiotic therapy such as chloramphenicol and ceftriaxone. The purpose of this study was to compare the cost-effectiveness of chloramphenicol and ceftriaxone which was given to adult patients who were diagnosed with typhoid fever in Sanglah Denpasar Hospital. A comparative study between two alternatives was conducted using the hospital perspective. Retrospective method was used to collect data from patient medical records, who was diagnosed and hospitalized in Sanglah Denpasar Hospital during January 2017 until July 2018. The cost analysis was perform using cost-effectiveness grid and cost-effectiveness ratio (ACER) methods. Cost-effectiveness grid showed that dominant of ceftriaxone for patient with typhoid fever. ACER analysis for ceftriaxone was IDR 2,097,170.88 with effectivenes (length of stay) 4.27 days, and was IDR 2,097,170.88 with effectiveness (the time of reaching normal temperature) 2.42 days. ACER analysis for chloramphenicol was IDR 2,555,464.22        with effectivenes (length of stay) 10.22 days, and was IDR 2,555,464.22 with effectiveness (the time of reaching normal temperature) 3.44 days. ACER analysis showed lower degree of ceftriaxone and higher effectiveness based on length of stay and the time of reaching normal temperature. The conclusion of this study is that ceftriaxone is more cost-effective than chloramphenicol.
