RESUMEN

BACKGROUND: This study aimed to assess the efficacy, tolerance, and cost-effectiveness of roxadustat treatment for anemia in patients with chronic kidney disease not receiving dialysis (CKD ND). METHODS: A meta-analysis was conducted to evaluate the clinical efficacy and tolerance of roxadustat for the correction of anemia associated with CKD ND, and a Markov model was developed to evaluate the cost-effectiveness of roxadustat compared with a placebo. RESULTS: The meta-analysis results showed that compared with a placebo, roxadustat treatment was associated with a remarkably higher rate of clinical response and the differences in the rate of adverse events between these two regimens were not significant. Moreover, roxadustat treatment (70 mg, three times per week) provided an additional 0.49 QALYs at a cost of $12,526 in the time horizon of 5 years, resulting in an ICER of $25,563 per QALY, with approximately 60% probability to be cost-effective at a $29,295 per QALY willingness-to-pay (WTP) threshold from the perspective of Chinese medical system. CONCLUSION: For the treatment of anemia in Chinese patients with CKD ND, roxadustat is much more effective than a placebo; moreover, it is cost-effective at conventional WTP thresholds.

RESUMEN

BACKGROUND AND OBJECTIVE: New direct-acting antivirals (DAAs) have high efficacy and tolerability in the treatment of hepatitis C virus (HCV) infection. The objective of this study was to assess the cost-effectiveness of elbasvir/grazoprevir (EBR/GZR) versus daclatasvir plus asunaprevir (DCV + ASV) in Chinese patients with chronic HCV genotype (GT) 1b infection stratified by cirrhosis status and treatment history. METHODS: A cohort state-transition model was constructed to simulate the course of chronic HCV infection in patients stratified by cirrhosis status and treatment history. The model projected lifetime outcomes and costs in terms of HCV treatment, laboratory tests, clinical procedures, and hospitalizations. Mean age of the study cohort at baseline was 45 years, based on published sources. Sustained virologic response (SVR) rates were derived from clinical trials. Healthcare resource utilization and health utilities were extracted or estimated from published studies in Chinese populations. The stability of the base-case analysis was validated by deterministic and probabilistic sensitivity analyses. RESULTS: In each subpopulation of Chinese patients, treatment with EBR/GZR dominated treatment with DCV + ASV, with lower costs and higher quality-adjusted life-years (QALYs). Sensitivity analysis demonstrated that EBR/GZR was the cost-effective option compared to DCV + ASV in 77.4-97.4% or 94.1-100% of model simulations in Chinese treatment-naïve or treatment-experienced patients, respectively, as the cost-effectiveness threshold changed from zero to US$24,150/QALY (three times GDP per capita in China). CONCLUSIONS: Treatment with EBR/GZR was the cost-effective option for patients with chronic HCV GT1b infection in China, regardless of cirrhosis status or treatment history.

RESUMEN

Aim: To evaluate the cost-effectiveness of the novel all-oral direct-acting antiviral regimen daclatasvir + asunaprevir (DUAL), versus interferon-based regimens for the treatment of chronic hepatitis C virus genotype 1b infection. Methods: Inputs for a lifetime Markov model were sourced from clinical trials and published literature. Outputs include disease management costs, life expectancy, quality-adjusted life-years and cost-effectiveness. Sensitivity analyses assessed the drivers of cost-effectiveness and sustained virologic response thresholds at which DUAL is cost-saving. Results: DUAL was associated with discounted incremental quality-adjusted life-years of 1.29-3.85 and incremental life-years of 0.85-2.59 per patient, with discounted lifetime cost savings of USD$1415-8525. Associated sustained virologic response rates could fall to 45.1-84.8%, while remaining dominant. Conclusion: Treatment with DUAL provides significant clinical benefit, while accruing lower lifetime costs.

RESUMEN

BACKGROUND: Hepatitis C is the second fastest growing infectious disease in China. The standard-of-care for chronic hepatitis C in China is Pegylated interferon plus ribavirin (PR), which is associated with tolerability and efficacy issues. An interferon- and ribavirin-free, all-oral regimen comprising daclatasvir (DCV) and asunaprevir (ASV), which displays higher efficacy and tolerability, has recently been approved in China. OBJECTIVES: This study is to estimate the cost-effectiveness of DCV+ASV (24 weeks) for chronic hepatitis C genotype 1b treatment-naïve patients compared with PR regimen (48 weeks) in China. METHODS: A cohort-based Markov model was developed from Chinese payer perspective to project the lifetime outcomes of treating 10,000 patients with an average age of 44.5 with two hypothetical regimens, DCV+ASV and PR. Chinese-specific health state costs and efficacy data were used. The annual discount rate was 5%. Base-case analysis and sensitivity analysis were conducted. RESULTS: For HCV Genotype 1b treatment-naïve patients, DCV+ASV proved to be dominant over PR, with a cost saving of ¥33,480(5,096 USD) and gains in QALYs and life years of 1.29 and 0.85, respectively. The lifetime risk of compensated cirrhosis, decompensated cirrhosis, hepatocellular carcinoma and liver-related death was greatly reduced with DCV+ASV. Univariate sensitivity analysis demonstrated that key influencers were the discount rate, time horizon, initial disease severity and sustained virological response rate of DCV+ASV, with all scenarios resulting in additional benefit. Probabilistic sensitivity analysis demonstrated that DCV+ASV has a high likelihood (100%) of being cost-effective. CONCLUSION: DCV+ASV is not only an effective and well-tolerated regimen to treat chronic HCV genotype 1b infection treatment-naïve patients, but also is more cost-effective than PR regimen. DCV+ASV can benefit both the public health and reimbursement system in China.

RESUMEN

BACKGROUND AND OBJECTIVES: Daclatasvir plus asunaprevir has shown superior efficacy and safety for treating hepatitis C virus genotype 1b infection in comparison with pegylated interferon and ribavirin. The objective of this analysis is to investigate the cost effectiveness of daclatasvir plus asunaprevir compared with interferon-α-based therapies from the perspective of the Chinese healthcare system. METHODS: A Markov model was established to measure economic and health outcomes of daclatasvir plus asunaprevir compared with general interferon-α plus ribavirin and pegylated interferon plus ribavirin for hepatitis C virus genotype 1b infection. We also considered the two following scenarios: 24 weeks of daclatasvir plus asunaprevir used as a second-line treatment for ineligible/intolerant and non-responding patients with HCV during 48 weeks of first-line interferon-α plus ribavirin (interferon-α plus ribavirin and daclatasvir plus asunaprevir) or pegylated interferon plus ribavirin (pegylated interferon plus ribavirin and daclatasvir plus asunaprevir) treatment. Clinical costs and utility inputs were derived from the published literature. The incremental cost-effectiveness ratio was shown as costs in US dollars per quality-adjusted life-years gained. Uncertainty was examined by one-way and probabilistic sensitivity analyses. RESULTS: Compared with interferon-α plus ribavirin, pegylated interferon and ribavirin, interferon-α plus ribavirin plus daclatasvir plus asunaprevir, and pegylated interferon plus ribavirin plus daclatasvir plus asunaprevir strategies, daclatasvir plus asunaprevir gained an additional 0.62, 0.32, 0.20, and 0.15 quality-adjusted life-year with increasing costs of US$11,950, US$671, US$8366, and -$3783, respectively. The incremental cost-effectiveness ratios of pegylated interferon and ribavirin, daclatasvir plus asunaprevir, interferon-α plus ribavirin and daclatasvir plus asunaprevir, and pegylated interferon plus ribavirin and daclatasvir plus asunaprevir against the baseline interferon-α plus ribavirin strategy were US$37,930, US$19,233, US$8495, and US$33,031 per quality-adjusted life-year gained. Daclatasvir plus asunaprevir and interferon-α plus ribavirin plus daclatasvir plus asunaprevir were presented as the cost-effective alternatives, and pegylated interferon plus ribavirin and pegylated interferon plus ribavirin and daclatasvir plus asunaprevir strategies dominated. The model outputs were sensitive to a patient's age, discount rate, and the risk ratio between pegylated interferon plus ribavirin and interferon-α plus ribavirin. CONCLUSIONS: Daclatasvir plus asunaprevir in the Chinese setting is likely to be cost effective for treating hepatitis C virus genotype 1b infection.

RESUMEN

OBJECTIVE: To evaluate the efficiency of resources allocation and sustainability of the use of netupitant+palonosetron (NEPA) for chemotherapy-induced nausea and vomiting (CINV) prophylaxis assuming the Italian National Health Service (NHS) perspective. A published Markov model was adapted to assess the incremental cost-utility ratio of NEPA compared with aprepitant (APR) + palonosetron (PALO), fosaprepitant (fAPR) + PALO, APR + ondansetron (ONDA), fAPR + ONDA in patients receiving a highly emetogenic chemotherapy (HEC) and with APR + PALO and fAPR + PALO in patients receiving a moderately emetogenic chemotherapy (MEC). SETTING: Oncology hospital department in Italy. METHODS: A Markov model was used to determine the impact of NEPA on the budget of the Italian NHS on a 5-day time horizon, corresponding to the acute and delayed CINV prophylaxis phases. Direct medical costs considered were related to antiemetic drugs, adverse events management, CINV episodes management. Clinical and quality of life data referred to previously published works. The budget impact analysis considered the aforementioned therapies plus PALO alone (for HEC and MEC) on a 5-year time horizon, comparing two scenarios: one considering the use of NEPA and one not considering its use. PRIMARY AND SECONDARY OUTCOME MEASURES: Incremental cost per quality adjusted life year (QALY) and differential economic impact for the Italian NHS between the two scenarios considered. RESULTS: NEPA is more effective and less expensive (dominant) compared with APR + PALO (for HEC and MEC), fAPR + PALO (for HEC and MEC), APR + ONDA (for HEC), fAPR + ONDA (for HEC). The use of NEPA would lead to a 5-year cost decrease of €63.7 million (€42.7 million for HEC and €20.9 million for MEC). CONCLUSIONS: NEPA allows an efficient allocation of resources for the Italian NHS and it is sustainable, leading to a cost decrease compared with a scenario which does not consider its use.

RESUMEN

Abstract: Background. Daclatasvir and asunaprevir dual therapy is approved for the treatment of HCV genotype 1b infection in several countries. Aim. To evaluate the efficacy and safety of daclatasvir and asunaprevir dual therapy in Turkish patients. Material and methods. Sixty-one patients with HCV genotype 1b were enrolled in the Turkish early access program. Most of the patients were in difficult-to-treat category. Patients were visited at each 4 week throughout the follow-up period. Laboratory findings and adverse events were recorded at each visit. Results. Fifty-seven of 61 enrolled patients completed 24 weeks of treatment. Two patients died as a result of underlying diseases at 12-14th weeks of treatment. Two patients stopped the treatment early as a consequence of virological breakthrough, and 2 patients had viral relapse at the post-treatment follow-up. Overall SVR12 rates were 90% (55/61) and 93.2% (55/59) according to intention-to-treat (ITT) and per protocol (PP) analysis respectively. In ITT analysis, SVR12 was achieved by 93% (13/14) in relapsers, 80% (12/15) in interferon-ineligible patients and 91% (20/22) in previous nonresponder patients. SVR12 rates were 86.5% and 91.4% in patients with cirrhosis according to ITT and PP analysis respectively. SVR12 was 95.8% in non-cirrhosis group in both analysis. Patients with previous protease inhibitor experience had an SVR12 of 87.5%. Common adverse events developed in 28.8% of patients. There were no treatment related severe adverse event or grade-4 laboratory abnormality. Conclusions. Daclatasvir and asunaprevir dual therapy is found to be effective and safe in difficult-to-treat Turkish patients with HCV genotype 1b infection.

RESUMEN

PURPOSE: Aggressive non-Hodgkin's lymphoma (aNHL) is associated with poor long-term survival after relapse, and treatment is limited by a lack of consensus regarding standard of care. Pixantrone was studied in a randomized trial in patients with relapsed or refractory aNHL who had failed ≥ 2 lines of therapy, demonstrating a significant improvement in complete or unconfirmed complete response and progression-free survival (PFS) compared with investigators' choice of single-agent therapy. The objective of this study was to assess the health economic implications of pixantrone versus current clinical practice (CCP) in the United Kingdom for patients with multiply relapsed or refractory aNHL receiving their third or fourth line of treatment. METHODS: A semi-Markov partition model based on overall survival and PFS was developed to evaluate the lifetime clinical and economic impact of treatment of multiply relapsed or refractory aNHL with pixantrone versus CCP. The empirical overall survival and PFS data from the PIX301 trial were extrapolated to a lifetime horizon. Resource use was elicited from clinical experts, and unit costs and utilities were obtained from published sources. The analysis was conducted from the perspective of the United Kingdom's National Health Service and personal social services. Outcomes evaluated were total costs, life-years, quality-adjusted life-years (QALYs), and cost per QALY gained. Deterministic and probabilistic sensitivity analyses were conducted to assess uncertainty around the results. FINDINGS: Pixantrone was estimated to increase life expectancy by a mean of 10.8 months per patient compared with CCP and a mean gain of 0.56 discounted QALYs. The increased health gains were associated with an increase in discounted costs of approximately £18,494 per patient. The incremental cost-effectiveness ratio of pixantrone versus CCP was £33,272 per QALY gained. Sensitivity and scenario analyses suggest that the incremental cost-effectiveness ratio was sensitive to uncertainty in the PFS and overall survival estimates and the utility values associated with each health state. IMPLICATIONS: Pixantrone may be considered both clinically effective and cost-effective for patients with multiply relapsed or refractory aNHL who currently have a high level of unmet need.

RESUMEN

The rationale for cost-effectiveness of modern muscle relaxants (MR) administration in general anesthesia was evaluated. New MRs are more expensive than traditionally used pipecuronium and succinylcholine. However, the old MRs are often required as a block reversion with anticholinesterase medicines at the end of surgery, the longer artificial lung ventilation and observation in patients during recovery in intensive care unit. It was found that the district military hospital had done an annual average of about 900 general anesthesia assisted with artificial ventilation and muscle relaxation. About 2% of all anesthesias accrue to short-term anesthesia, the 27% to medium-term and 71% to long-term. 81% of the medium-term anesthesia accrue small hospitals. According to cost/effectiveness the most optimal muscle relaxants administration scheme for short-term (up to 30 min) anesthesia was mivacurium, for the operation of medium duration (30-120 min)--rocuronium, for long-term (120 min)--pipecuronium. An electronic form of annual report, which allows to obtain the necessary data for calculation of annual muscle relaxants demand and costs both in hospital and in the whole of the armed forces quickly, was developed.

RESUMEN

Chemotherapy is associated with a variety of side effects, and many of these can be dose-limiting. One of the most dreaded side effects for patients receiving chemotherapy is nausea and vomiting, however. Although in the last 2 decades there have been several advances in the development of new therapies for prevention of chemotherapy-induced nausea and vomiting (CINV), recent pharmacologic advances have significantly improved control of this feared side effect. Antiemetic guidelines help clinicians manage CINV and are updated frequently. Ongoing studies further define appropriate management of patients with CINV; of particular interest is delayed nausea and vomiting. With the addition of the long-acting serotonin antagonist, palonosetron, and the unique neurokinin-1 antagonist, aprepitant, control of CINV has improved considerably for those patients receiving chemotherapy. This article discusses CINV and recent pharmacologic advances in controlling this side effect. Guidelines for the management of CINV are reviewed.

RESUMEN

Remifentanil, mivacurium and ropivacaine are the latest innovations in clinical anaesthesia and have gained increasing importance in daily practise due to their unique pharmacodynamic and pharmacokinetic properties. However, drug acquisition costs for these agents are considerably higher in most countries than for comparable substances. This review provides a systematic, critical appraisal of pharmacoeconomic studies with remifentanil, mivacurium and ropivacaine, primarily based on prospective, randomised trials. Results from analyses using cost-minimising techniques stress the issue of the higher drug acquisition costs. However, studies using a more sophisticated method (e.g., cost-effectiveness analysis) indicate comparable costs or even financial advantage in favour of the newer investigative drugs remifentanil, mivacurium and ropivacaine.

RESUMEN

Large-scale, renewable supplies of chemical constituents derived from marine invertebrates have limited development of potential new natural product drugs. This paper describes the development of two in-sea aquaculture systems designed and engineered for production of large quantities of biomass for two species of marine invertebrates desired for their natural product chemical constituents. The two invertebrates and their products were: (1) the cosmopolitan, arborescent bryozoan Bugula neritina (Phylum Bryozoa) for its anticancer chemical constituent bryostatin 1; and (2) Ecteinascidia turbinate (Phylum Tunicata) the source of anticancer ecteinascidin 743. For the third invertebrate Phylum Porifera, and its representative sponge Acanthella cavernosa (desired for its anti-parasitic and anti-infective kalihinols) in-sea systems were not developed in favor of controlled environment tank aquaculture systems. For the bryozoan and tunicate, projected economics for commercial-scale in-sea production proved cost effective. This was in contrast to the controlled environment sponge culture tank system, which did not prove to be economical due to inherent slow growth and low natural product yields of the sponge in culture.

RESUMEN

PURPOSE: Atypical cholinesterase prolongs the duration of neuromuscular blocking drugs such as succinylcholine and mivacurium. Measuring the dibucaine number identifies patients who are at risk. This study shows the frequency distribution of dibucaine numbers routinely measured and discusses avoidable clinical problems and economic implications. METHODS: Dibucaine numbers were measured on a Hitachi 917-analyzer and all dibucaine numbers recorded over a period of 4 years were taken into consideration. Repeat observations were excluded. RESULTS: A total of 24,830 dibucaine numbers were analysed and numbers below 30 were found in 0.07% ( n=18) giving an incidence of 1:1,400. Dibucaine numbers from 30 to 70 were found in 1.23% ( n=306). On the basis of identification of the Dibucaine numbers we could avoid the administration of succinylcholine or mivacurium resulting in a cost reduction of 12,280 Euro offset against the total laboratory costs amounting to 10,470 Euro. CONCLUSIONS: An incidence of 1:1,400 of dibucaine numbers below 30 is higher than documented in the literature. Therefore, routine measurement of dibucaine number is a cost-effective method of identifying patients at increased risk of prolonged neuromuscular blockade due to atypical cholinesterase.

RESUMEN

PURPOSE: To compare equi-lasting doses of a short-acting (mivacurium) to an intermediate-acting (rocuronium) neuromuscular relaxant, with regard to intubating conditions, efficacy, number of maintenance doses, hemodynamic alterations, adverse events and costs, in patients undergoing laparoscopic gynecological surgery. METHODS: Sixty patients were randomly allocated to receive either 0.2 mg*kg(-1) (3 x ED(95)) mivacurium or 0.5 mg*kg(-1) (1.7 x ED(95)) rocuronium, under propofol/fentanyl anesthesia. T1, first twitch of the train-of-four (TOF) and TOF ratio (T4:T1) were used to evaluate neuromuscular block using the Relaxometer(R) mechanomyograph. The trachea was intubated when T1 was maximally suppressed. Neuromuscular block was maintained at 25% T1 with equi-lasting doses of 0.075 mg*kg(-1) mivacurium or 0.15 mg*kg(-1) rocuronium. RESULTS: Mean (min) +/- SD mivacurium onset time (1.9 +/- 0.4) was longer than that of rocuronium (1.3 +/- 0.3). This did not yield a statistical difference in intubating conditions between the two groups. Interval 25-75% T1 recovery and time to 0.8 TOF recovery were prolonged following rocuronium (11.9 +/- 3.9, 52.6 +/- 15.5 respectively) compared to mivacurium (6.7 +/- 2.3, 39.2 +/- 8.1 respectively). More patients, 22/30, required mivacurium maintenance doses compared to 14/30 patients in the rocuronium group. Arterial blood pressure declined and 13/30 patients manifested erythema following mivacurium administration. The acquisition costs of rocuronium (6.93 Euro/patient) were 23% lower compared to mivacurium (8.96 Euro/patient). CONCLUSION: Equi-lasting doses of rocuronium resulted in favourable intubating conditions more rapidly, improved hemodynamic stability, required less frequent administration of maintenance doses and were not associated with erythema, compared to mivacurium.

RESUMEN

BACKGROUND: The present study compared the quality of neuromuscular block and costs after equipotent doses of mivacurium and vecuronium in the context of paediatric ENT surgery. METHODS: A total of 30 children undergoing elective tonsillectomy were included and randomised in two groups (n = 15 for each) according to the neuromuscular blocking agent (NMBA) used. Anaesthesia was induced with alfentanil (15 micrograms/kg), propofol (3 mg/kg) and either 0.2 mg/kg mivacurium or 0.14 mg/kg vecuronium. For maintenance of anaesthesia propofol (8-12 mg/kg/h) was given. Neuromuscular block was assessed by electromyography using train-of four stimulation and the following parameters were quantified: Twitch height (T1) 2 min after the initial bolus of the myorelaxant; duration until recovery to 10% T1, number and duration of bolus injections of the myorelaxant needed to maintain neuromuscular block to a T1 < 10%. In addition, the intubating conditions, number of patients needing pharmacological reversal at the end of surgery, adverse reactions and the costs for neuromuscular block and pharmacological antagonization were assessed. RESULTS: Intubation conditions were comparable between both study groups: mivacurium--excellent: 7, good: 5, not acceptable: 1; vecuronium--excellent: 11, good: 4 (n.s.). T1 at 2 min was 16 (15)% for mivacurium and 6 (9)% for vecuronium (P < 0.05). Time to 10% T1 recovery was 6.1 (1.7) min for mivacurium and 21.8 (3.7) min for vecuronium (P < 0.01). In the mivacurium group 7 repetitive doses (range: 4-18) were needed to maintain T1 < 10% during surgery, whereas children treated with vecuronium needed only 1 maintenance dose (range: 0-2) (P < 0.01). Two children in the mivacurium group and 11 in the vecuronium group required pharmacological reversal of the NMB at the end of surgery (P < 0.01). The overall costs of NMB were significantly higher in the mivacurium group as compared to vecuronium 12.88 (4.5) Euro vs 9.96 (2.4) Euro; P < 0.05. CONCLUSIONS: In conclusion, mivacurium-induced NMB is of very short duration in paediatric patients, and therefore repetitive doses are required to maintain a deep neuromuscular block. Nevertheless, residual paralysis is less frequent after mivacurium. The neuromuscular block after mivacurium was more expensive and residual paralysis less frequent compared to vecuronium.

RESUMEN

STUDY OBJECTIVE: To determine whether placing price labels on the vial caps of muscle relaxants increases cost consciousness among anesthesiologists. DESIGN: Retrospective study. SETTING: University hospital departments of anesthesia and pharmacy. MEASUREMENTS AND MAIN RESULTS: We placed price labels on the vial caps of all muscle relaxants for a study period of 1 year. At the beginning of the investigation, we informed the anesthesiologists of the study, discussed the prices for different muscle relaxants, and encouraged utilizing less expensive muscle relaxants whenever possible without compromising patient care. The price labels on the vial caps served as visual reminders of the various costs of muscle relaxants during daily practice. We compared the total amount spent on each muscle relaxant during the period from October 1993 to September 1994 with the period from October 1994 to September 1995. The total number of surgical cases from October 1993 to September 1994 and from October 1994 to September 1995 was unchanged and equaled 20,389 and 20,358 cases, respectively. Expenditures for pancuronium increased 104.1%. Total expenditure decreased by 12.5%, with a net savings of $47,111. CONCLUSION: Expenditures for the less costly pancuronium increased while expenditures for vecuronium and atracurium decreased. Price labeling of muscle relaxants in conjunction with education reduces total pharmacy expenditure on muscle relaxants.
