Introduction:Influenza A (H1N1) virus is the most relevant virus in death by flu complications. Oseltamivir and zanamivir are used for influenza prophylaxis in epidemics. We aimed to evaluate the efficacy of chemoprophylaxis for influenza A (H1N1) for the Brazilian health care system.Methods:We systematically searched the literature to identify efficacy results. Costs assessed from the system perspective were obtained from official Brazilian Ministry of Health systems, and completed from medical care at a university hospital of Campinas, Sao Paulo. Model outcomes were quality-adjusted life years (QALY) with willingness to pay BRL 30,000 (USD 8,212)/QALY and prevention of H1N1. A decision-tree model was used to calculate the incremental cost-effectiveness ratios for prophylaxis, compared to no prophylaxis. Deterministic and probabilistic sensitivity analyses were used to test robustness of the model.Results:Prophylaxis had 70 percent adherence to treatment, 9 percent adverse events, effectiveness in avoiding H1N1 (relative risk = 0.43; 95% confidence interval: 0.33, 0.57); no evidence of prophylaxis efficacy for complication, hospitalization and death was found. Both scenarios had 14 percent H1N1 attack rate, 67 percent of ambulatorial consult, 43 percent of inpatient care, 14 percent of deaths in hospital, 23 percent of intensive care where death was 40 percent. Utility was 0.50 during H1N1 infection, 0.23 with hospitalization, 0.195 less with adverse events, 0 for deaths and 0.885 for healthy. Cost was BRL39 (USD 11) for chemoprophylaxis; BRL 12 (USD 4) for outpatient care; BRL 5,728 (USD 1,568) for hospital admission; BRL 19,217 (USD 5,260) for intensive care; and BRL 292 (USD 80) for adverse events. Incremental cost of prophylaxis was BRL 40 (USD 11) and utility increased 0.004, which mean saving of BRL 2,921 (USD 780)/QALY. Prophylaxis saves BRL 338 (USD 92) per H1N1 case avoided. Univariate and probabilistic sensitivity analysis assure the robustness of results, with 43 percent probability of being of lower cost and higher effectiveness.Conclusions:Prophylaxis is cost-effective from the health care system perspective using utility and avoided H1N1 cases outcomes.

Introduction:Aducanumab was granted accelerated approval with a conflicting evidence base, near-unanimous FDA Advisory Committee vote to reject approval, and a widely criticized launch price of $56,000 per year. The objective of this analysis was to estimate its cost-effectiveness.Methods:We developed a Markov model to compare aducanumab in addition to supportive care to supportive care alone over a lifetime horizon. Results were presented from both the health system and modified societal perspective. The model tracked the severity of disease and the care setting. Incremental cost-effectiveness ratios were calculated, and a threshold analysis was conducted to estimate at what price aducanumab would meet commonly used cost-effectiveness thresholds.Results:Using estimates of effectiveness based on pooling of data from both pivotal trials, patients treated with aducanumab spent four more months in earlier stages of AD. Over the lifetime time horizon, treating a patient with aducanumab results in 0.154 more QALYs gained per patient and 0.201 evLYGs per patient from the health care system perspective, with additional costs of approximately $204,000 per patient. The incremental outcomes were similar for the modified societal perspective. At the list price of $56,000 per year, the cost-effectiveness ranged from $1.02 million per evLYG to $1.33 million per QALY gained from the health care system perspective; and from $938,000 per evLYG to $1.27 million per QALY gained in the modified societal perspective. The annual price to meet commonly used cost-effectiveness thresholds ranged from $2,950 to $8,360, which represents a discount of 85-95% off from the annual launch price set by the manufacturer. Using estimates of effectiveness based only on the trial that suggested a benefit, the mean incremental cost was greater than $400,000 per QALY gained.Discussion:Patients treated with aducanumab received minimal improvements in health outcomes at considerable cost. This resulted in incremental cost-effectiveness ratios that far exceeded commonly used value thresholds, even under optimistic treatment effectiveness assumptions. These findings are subject to the substantial uncertainty regarding whether aducanumab provides any true net health benefit, but evidence available currently suggests that an annual price of aducanumab of $56,000 is not in reasonable alignment with its clinical benefits.

Abstract Study Objectives To determine cost-effectiveness of continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) in Australia for 2017–2018 to facilitate public health decision-making. Methods Analysis was undertaken of direct per-person costs of CPAP therapy (according to 5-year care pathways), health system and other costs of OSA and its comorbidities averted by CPAP treatment (5-year adherence rate 56.7%) and incremental benefit of therapy (in terms of disability-adjusted life years [DALYs] averted) to determine cost-effectiveness of CPAP. This was expressed as the incremental cost-effectiveness ratio (= dollars per DALY averted). Direct costs of CPAP were estimated from government reimbursements for services and advertised equipment costs. Costs averted were calculated from both the health care system perspective (health system costs only) and societal perspective (health system plus other financial costs including informal care, productivity losses, nonmedical accident costs, deadweight taxation and welfare losses). These estimates of costs (expressed in US dollars) and DALYs averted were based on our recent analyses of costs of untreated OSA. Results From the health care system perspective, estimated cost of CPAP therapy to treat OSA was $12 495 per DALY averted while from a societal perspective the effect was dominant (−$10 688 per DALY averted) meaning it costs more not to treat the problem than to treat it. Conclusions These estimates suggest substantial community investment in measures to more systematically identify and treat OSA is justified. Apart from potential health and well-being benefits, it is financially prudent to do so.

BACKGROUND:Clostridium difficileinfection (CDI) represents a public health problem with increasing incidence and severity.OBJECTIVE: To evaluate the clinical and economic consequences of vancomycin compared with fidaxomicin in the treatment of CDI from the Canadian health care system perspective.METHODS: A decision-tree model was developed to compare vancomycin and fidaxomicin for the treatment of severe CDI. The model assumed identical initial cure rates and included first recurrent episodes of CDI (base case). Treatment of patients presenting with recurrent CDI was examined as an alternative analysis. Costs included were for study medication, physician services and hospitalization. Cost effectiveness was measured as incremental cost per recurrence avoided. Sensitivity analyses of key input parameters were performed.RESULTS: In a cohort of 1000 patients with an initial episode of severe CDI, treatment with fidaxomicin led to 137 fewer recurrences at an incremental cost of $1.81 million, resulting in an incremental cost of $13,202 per recurrence avoided. Among 1000 patients with recurrent CDI, 113 second recurrences were avoided at an incremental cost of $18,190 per second recurrence avoided. Incremental costs per recurrence avoided increased with increasing proportion of cases caused by the NAP1/B1/027 strain. Results were sensitive to variations in recurrence rates and treatment duration but were robust to variations in other parameters.CONCLUSIONS: The use of fidaxomicin is associated with a cost increase for the Canadian health care system. Clinical benefits of fidaxomicin compared with vancomycin depend on the proportion of cases caused by the NAP1/B1/027 strain in patients with severe CDI.

Introduction:For patients with bifascicular block and syncope of unknown origin, different American Heart Association guidelines give Class 2A recommendations for two treatments: the implantable loop recorder (ILR) and empiric pacemaker insertion (PM). Equipoise reflected in guidelines may contribute to uncertainty in management and inefficient resource use. The objective of this analysis is to determine the cost-effectiveness of ILR compared to PM in the management of older adults (age>50 years) with bifascicular block and syncope over two years, from the perspective of a Canadian publicly funded health care system, in the Syncope: Pacing or Recording In ThE Later Years (SPRITELY) trial.Methods:Resource utilization data was collected throughout the trial, and unit costs were assigned (2017 Canadian dollars). Utility was measured at baseline and annually with the EQ-5D-3L. Quality adjusted life years (QALYs) were calculated as area-under-the-curve, and adjusted for baseline imbalances in utility. Confidence intervals for the incremental cost effectiveness ratio were generated with non-parametric bootstrapping.Results:Mean cost in participants randomized to PM was CAD 9,759 (USD 7,400), compared to CAD 13,453 (USD 10,200) in participants randomized to ILR. The ILR strategy resulted in 0.020 QALYs more than the PM strategy. The incremental cost effectiveness ratio was CAD 186,553 (95% CI: −831,950–1,191,816) (USD 141,900, 95% CI: −632,740–906,440) per additional QALY. In 1,000 bootstrapped replicates, the cost of the ILR strategy was always greater than that of the PM strategy. At the threshold of CAD 50,000 (USD 38,000) per additional QALY, the probability that the ILR strategy is the cost effective option is 0.504.Conclusions:ILR costs were greater than PM costs, with little difference in QALY outcomes over two-years. Findings are generalizable to patients similar to SPRITELY participants, from the perspective of the Canadian health care system. However, practice pattern variation and payment systems inhibit generalizability to other countries. Future analysis will explore cost and QALY outcomes in countries that participated in the SPRITELY trial.
