Potential cost-effectiveness and benefit-cost ratios of adult pneumococcal vaccination in Germany.

ABSTRACT: BACKGROUND:Invasive (IPD, defined as detection of pneumococci in sterile body fluids like meningitis or bacteremic pneumonia) and non-invasive Streptococcus pneumoniae infections (i.e. non-bacteremic pneumonia, otitis media) in adults are associated with substantial morbidity, mortality and costs. In Germany, Pneumococcal polysaccharide vaccination (PPV23) is recommended for all persons >60?years and for defined risk groups (age 5-59). The aim of this model was to estimate the potential cost-effectiveness and benefit-cost ratios of the adult vaccination program (18?years and older), considering the launch of the pneumococcal conjugate vaccine for adults (PCV13). METHODS:A cross-sectional steady state Markov model was developed to estimate the outcomes of PCV13, PPV23 vaccination schemes and 'no vaccination'. Conservative assumptions were made if no data were available for PCV13 and PPV23 respectively. The effectiveness of individual pneumococcal vaccination in adults was adjusted for expected indirect effects due to the vaccination in infants. Data on incidences, effectiveness and costs were derived from scientific literature and publicly available databases. All resources used are indicated. Benefit-cost ratios and cost-effectiveness were evaluated from the perspective of the German Statutory Health Insurance as well as from social perspective. RESULTS:Under the assumption that PCV13 has a comparable effectiveness to PCV7, a vaccination program with PCV13 revealed the potential to avoid a greater number of yearly cases and deaths in IPD and pneumonia in Germany compared to PPV23. For PCV13, the costs were shown to be overcompensated by monetary savings resulting from reduction in the use of health care services. These results would render the switch from PPV23 to PCV13 as a dominant strategy compared to PPV23 and 'no vaccination'. Given the correctness of the underlying assumptions every Euro spent on the PCV13 vaccination scheme yields savings of 2.09 € (social perspective: 2.16 €) compared to PPV23 and 1.27 € (social perspective: 1.32 €) compared to 'no vaccination', respectively. CONCLUSIONS:Results of the model indicate that the health economic benefit of immunizing adults with PCV13 can be expected to outperform the sole use of PPV23, if the effectiveness of PCV13 is comparable to the effectiveness of PCV7.

Project description:INTRODUCTION:In Germany, a 23-valent polysaccharide pneumococcal vaccine (PPSV23) is recommended for elderly (60+) and patients 16+ with chronic diseases not associated with immune suppression. For all other patients at risk, sequential immunization with a 13-valent pneumococcal conjugate vaccine (PCV13) first, followed by PPSV23 is recommended. Repeated vaccination with PPSV23 is recommended every 6 years after individual assessment by the physician. This was adopted into the vaccination directive with binding reimbursement and funding. However, additional voluntary services allow statutory health insurances to differentiate from each other. Aim of this study is to estimate the cost-effectiveness of voluntary service scenarios compared to the strategy in place to support informed decision making. METHODS:A microsimulation framework with Markov-type process of a population susceptible to pneumococcal disease over a lifetime horizon was developed to compare effectiveness and cost-effectiveness of different vaccination strategies. We simulated 1,000 iterations for seven scenarios. Assumptions were derived from published literature and probabilistic sensitivity analysis was run to show the robustness of the model. RESULTS:Our study indicates that all voluntary service strategies could prevent further clinical cases compared to the existing policy. Depending on the scenario, 48-142 invasive pneumococcal disease (IPD), 24,000-45,000 hospitalized all-cause nonbacteremic pneumonia (NBP), 15,000-45,000 outpatient NBP cases, and 4,000-8,000 deaths could be avoided on average. This refers to potential savings of €115 Mio. - €187 Mio. for medical and non-medical costs. Additional costs per patient for the payer are €2.48 to €7.13 and for the society €2.20 to €6.85. The ICER per LYG ranged from €3,662 to €23,061 (payer) and €3,258 to €29,617 (societal). All but one scenario was cost-effective in ≥60% of the generated 1,000 simulations. CONCLUSION:Compared to the vaccination strategy in place, the different hypothetical scenarios can be considered cost-effective and suitable as additional voluntary services.

Project description:ObjectiveThe Ministry of Health (MOH), Mongolia, is considering introducing 13-valent pneumococcal conjugate vaccine (PCV13) in its national immunization programme to prevent the burden of disease caused by Streptococcus pneumoniae. This study evaluates the cost-effectiveness and budget impact of introducing PCV13 compared to no PCV vaccination in Mongolia.MethodsThe incremental cost-effectiveness ratio (ICER) of introducing PCV13 compared to no PCV vaccination was assessed using an age-stratified static multiple cohort model. The risk of various clinical presentations of pneumococcal disease (meningitis, pneumonia, non-meningitis non-pneumonia invasive pneumococcal disease and acute otitis media) at all ages for thirty birth cohorts was assessed. The analysis considered both health system and societal perspectives. A 3+0 vaccine schedule and price of US$3.30 per dose was assumed for the baseline scenario based on Gavi, the Vaccine Alliance's advance market commitment tail price.ResultsThe ICER of PCV13 introduction is estimated at US$52 per disability-adjusted life year (DALY) averted (health system perspective), and cost-saving (societal perspective). Although indirect effects of PCV have been well-documented, a conservative scenario that does not consider indirect effects estimated PCV13 introduction to cost US$79 per DALY averted (health system perspective), and US$19 per DALY averted (societal perspective). Vaccination with PCV13 is expected to cost around US$920,000 in 2016, and thereafter US$820,000 every year. The programme is likely to reduce direct disease-related costs to MOH by US$440,000 in the first year, increasing to US$510,000 by 2025.ConclusionIntroducing PCV13 as part of Mongolia's national programme appears to be highly cost-effective when compared to no vaccination and cost-saving from a societal perspective at vaccine purchase prices offered through Gavi. Notwithstanding uncertainties around some parameters, cost-effectiveness of PCV introduction for Mongolia remains robust over a range of conservative scenarios. Availability of high-quality national data would improve future economic analyses for vaccine introduction.

Project description:BackgroundIntroduction of pneumococcal conjugate vaccines (PCVs) has substantially reduced disease burden due to Streptococcus pneumoniae, a leading cause of childhood morbidity and mortality globally. However, PCVs are among the most expensive vaccines, hindering their introduction in some settings and threatening sustainability in others. We aimed to assess the effect and cost-effectiveness of introduction of 13-valent PCV (PCV13) vaccination globally.MethodsWe assessed the incremental cost-effectiveness ratio of PCV13 introduction by integrating two models: an ecological model (a parsimonious, mechanistic model validated with data from post-seven-valent PCV introduction in 13 high-income settings) to predict the effect of PCV on childhood invasive pneumococcal disease, and a decision-tree model to predict a range of clinical presentations and economic outcomes under vaccination and no-vaccination strategies. The models followed 30 birth cohorts up to age 5 years in 180 countries from 2015 to 2045. One-way scenario and probabilistic sensitivity analyses were done to explore model uncertainties.FindingsWe estimate that global PCV13 use could prevent 0·399 million child deaths (95% credible interval 0·208 million to 0·711 million) and 54·6 million disease episodes (51·8 million to 58·1 million) annually. Global vaccine costs (in 2015 international dollars) of $15·5 billion could be partially offset by health-care savings of $3·19 billion (2·62 billion to 3·92 billion) and societal cost savings of $2·64 billion (2·13 billion to 3·28 billion). PCV13 use is probably cost-effective in all six UN regions. The 71 countries eligible for support from Gavi, the Vaccine Alliance, account for 83% of PCV13-preventable deaths but only 18% of global vaccination costs. The expected cost of PCV vaccination globally is around $16 billion per year.InterpretationOur findings highlight the value of Gavi's support for PCV introduction in low-income countries and of efforts to improve the affordability of PCVs in countries not eligible for, or transitioning from, Gavi support.FundingWorld Health Organization; Gavi, the Vaccine Alliance; and the Bill & Melinda Gates Foundation.

Project description:BACKGROUND:Changing pneumococcal disease epidemiology due to childhood vaccination has prompted re-examination of US adult pneumococcal vaccination policies, as have considerations of greater pneumococcal disease incidence and higher prevalence of conditions that increase risk in underserved minority populations. Prior analyses suggest routine pneumococcal vaccination at age 50 could be considered, which could disproportionately benefit underserved populations. METHODS:A Markov cohort model estimated the cost-effectiveness of US pneumococcal vaccination policies in hypothetical 50-year-old underserved minority and general population cohorts. Strategies included receiving one or both available pneumococcal vaccines based on age- or chronic condition-specific criteria. US databases and medical literature data calibrated pneumococcal illness incidence, vaccine serotype distributions, age- and race-specific chronic condition distributions, and costs. Black population data were used as a proxy for underserved minorities. We took a US healthcare perspective, discounting at 3%/year. One-way and probabilistic sensitivity analyses were performed and scenarios modeling differing vaccine assumptions were examined. RESULTS:In both black and general population 50-year-olds, giving both pneumococcal vaccines to all 50-year-olds prevented the most disease, but cost >$250,000 per quality adjusted life year (QALY) gained. Current CDC recommendations (both vaccines for the immunocompromised, polysaccharide vaccine for other high-risk conditions) were economically favorable in either population when analyses assumed polysaccharide vaccine was ineffective against nonbacteremic pneumococcal pneumonia (NBP). If polysaccharide vaccine is effective against NBP or if less complex age-based vaccination recommendations result in increased vaccine uptake, giving polysaccharide vaccine to all 50-year-olds cost <$100,000/QALY; this effect was more pronounced in black cohorts. Results were robust in 1-way and probabilistic sensitivity analyses. CONCLUSIONS:Despite changes in pneumococcal epidemiology, current CDC recommendations were favored in underserved minority and general population cohorts. Polysaccharide vaccine for all 50-year-olds could be considered under some vaccine uptake and effectiveness assumptions, particularly if mitigating racial health disparities in pneumococcal disease is a priority.

Project description:Background/objectivesRecently revised vaccination recommendations for US adults, aged 65 years and older, include both 23-valent pneumococcal polysaccharide vaccine (PPSV23) and 13-valent pneumococcal conjugate vaccine (PCV13), with PCV13 now recommended for immunocompetent older people based on shared decision making. The public health impact and cost-effectiveness of this recommendation or of pneumococcal vaccine uptake improvement interventions are unclear.DesignMarkov decision analysis.Setting and participantsHypothetical 65-year-old general and black population cohorts.InterventionCurrent pneumococcal vaccination recommendations for US older people, an alternative policy omitting PCV13 in immunocompetent older people, and vaccine uptake improvement programs.ResultsThe current pneumococcal vaccination recommendation was the most effective strategy, but afforded slight public health benefits compared to an alternative (PPSV23 for all older people plus PCV13 for the immunocompromised) and cost greater than $750 000 per quality-adjusted life-year (QALY) gained in either population group with a vaccine uptake improvement program (absolute uptake increase = 12.3%; cost = $1.78/eligible patient) in place. The alternative strategy was more economically favorable, but cost greater than $100 000/QALY in either population, with or without an uptake intervention. Results were robust in sensitivity analyses; however, in black older people, the alternative strategy with an uptake program was most likely to be favored in probabilistic sensitivity analyses at a $150 000/QALY gained threshold.ConclusionCurrent pneumococcal vaccination recommendations for US older people are economically unfavorable compared to an alternative strategy omitting PCV13 in the immunocompetent. The alternative recommendation with an uptake improvement program may be economically reasonable in black population analyses and could be worth considering as a population-wide recommendation if mitigating racial disparities is a priority.

Project description:BackgroundEthiopia was among the 15 countries that, together accounted for 64% of the world's severe episodes of pneumonia among children below the age of 5 in 2011. To reduce this burden, the 10-valent pneumococcal conjugate vaccine (PCV 10) was introduced into the general childhood national immunization program in Ethiopia in 2011. However, there is little evidence on its cost-effectiveness, and the aim of this study was to estimate the cost-effectiveness of the introduction of PCV 10 vaccination in the Ethiopian setting.MethodsThe cost-effectiveness analysis was carried out based on a quasi-experimental evaluation of implementing PCV 10 at the Butajira rural health program site in Ethiopia. The intervention and the control groups consisted 876 and 1010 children, respectively. Using data from program site's surveillance system database as a framework, health outcome and vaccination data were collected from medical records, immunization registration books and reports. Disability- Adjusted Life Year (DALY) was a main health outcome metric complimented by incidence of acute lower respiratory infection/1000-person years. Vaccination and treatment costs were collected by document review and cross-sectional household survey.ResultsIn the intervention cohort, 626 of 876 (71.5%) children received PCV 10 vaccination. Until the first year of life, the incidence of acute lower respiratory infection was higher in the intervention group. After the first year of life, the incidence rate was 35.2 per 1000-person years in the intervention group compared to 60.4 per 1000-person years in the control group. The incremental cost-effectiveness ratio (ICER) per averted DALY for the intervention group during the total follow-up period was (2013 US$) 394.3 (undiscounted) and 413.8 (discounted). The ICER per averted DALY excluding the first year of life was (2013 US$) 225 (undiscounted) and 292.7 (discounted).ConclusionCompared to the WHO's suggested cost-effectiveness threshold value, the results indicate that the general childhood PCV 10 vaccination was a cost-effective intervention in the Butajira rural health program site.
