Pharmacoeconomic analysis of rituximab and belimumab therapy in patients with systemic lupus erythematosus

The progressive course of systemic lupus erythematosus (SLE) with high activity and severe internal organs involvement requires the prescription of expensive biologic disease-modifying antirheumatic drugs (bDMARDs), rituximab (RTM) and belimumab (BLM), whose comparative clinical and economic efficacy has not been adequately studied.Objective: to evaluate the clinical and economic efficacy of RTM and BLM therapy in patients with SLE.Material and methods. The study included 50 SLE patients who were divided into two groups and received RTM (group 1, n=25) or BLM (group 2, n=25) therapy for 12 months. The clinical and economic analysis was performed with the cost-effectiveness method using the cost-per-responder (CPR) model. A clinically significant improvement in SLEDAI-2K (Systemic Lupus Erythematosus Disease Activity Index modified 2K; Δ ≥4) was considered a response to therapy. Direct and indirect costs were considered in the analysis.Results and discussion. Against a background of therapy, there was a decrease in SLE activity with a decrease in median SLEDAI-2K in group 1 from 12 [10.5; 18] to 8 [4; 10] and in group 2 from 10 [8; 14.5] to 4 [2; 4] (p< 0.001 in both cases). A clinically significant improvement was observed in 56% of patients in group 1 and 72% of patients in group 2. The peculiarities of the BLM dosing regimen caused higher (1.7 times) total costs than in the case of RTM. According to the CPR value, RTM showed a greater benefit (1.3 times) than BLM (954 thousand rubles versus 1.25 million rubles). The incremental cost-effectiveness ratio (ICER) was 1.4 million rubles, which does not exceed the threshold of willingness to pay for a domestic patient.Conclusion. When comparing BLM and RTM therapy for SLE patients in real-life clinical practice, greater clinical and economic efficiency was demonstrated for RTM. BLM therapy was found to be “cost-effective”.

Cost-effectiveness of pharmaceutical smoking cessation intervention in China primary cancer prevention

Objectives: To evaluate the cost-effectiveness of typical pharmaceutical smoking cessation intervention strategies in China in the context of primary cancer prevention. Methods: Markov cohort simulation models were established to simulate the burden of 12 smoking caused cancer, including lung cancer, oral cancer, nasopharyngeal cancer, laryngeal cancer, esophageal cancer, gastric cancer, pancreatic cancer, liver cancer, kidney cancer, bladder cancer, cervical cancer, and acute myeloid leukemia. Taking incremental cost effectiveness ratio (ICER) as the main indicator, the model sets one year as the cycling period for 50 periods and simulates the cohort of 10 000 thirty-five-year-old current smokers with various smoking cessation strategies. To ensure the robustness of conclusion, univariate sensitivity analysis, probability sensitivity analysis, and age-group sensitivity analysis were conducted. Results: The results showed that varenicline intervention was the most cost-effective intervention. Compared to the next most effective option, incremental cost of each additional quality-adjusted life year is 11 140.28 yuan, which is below the threshold of willingness to pay (1 year GDP per capita). The value of ICER increased as the increasing age group of adopting intervention, but neither exceeded the threshold of willingness to pay. One-way sensitivity analysis showed that the value of discount rate, the hazard ratio and cost of intervention strategy had a greater impact on the result of ICER. Conclusion: In China, the use of varenicline to quit smoking is highly cost effective in the context of cancer primary prevention, especially for younger smokers.

Análise de custo-efetividade do tratamento com terapia compressiva na cicatrização de úlceras venosas

Objective: to analyze the cost-effectiveness and calculate the incremental cost-effectiveness ratio of multilayer compressive treatment in relation to inelastic (Unna boot and short stretch) therapy according to the current literature. Method: quantitative study about cost-effectiveness through modeling with the aid of TreeAge® software for construction of the decision tree. The anticipated assumptions were obtained by using secondary literature data to estimate the cost and effectiveness of the assumed parameters. A systematic literature review with meta-analysis was performed for this end. Results: the decision tree after Roll Back showed that the multilayer therapy dominated the alternatives in the base case, representing an intermediate cost per application, although with the highest effectiveness. The cost-effectiveness analysis graph also showed extended dominance of the Unna boot in relation to the short stretch bandage. The sensitivity analysis showed that multilayer bandage remains a more cost-effective alternative, within the threshold of willingness to pay. Conclusion: the most cost-effective alternative was multilayer bandage, considered the gold standard in the literature. The second most cost-effective alternative was the Unna boot, the most used therapy in Brazil.

A clinical and economic analysis of the use of dapagliflozin in patients with chronic heart failure in the entire spectrum of left ventricular ejection fraction in the Russian Federation

To estimate the cost-effectiveness of dapagliflozin across the range of ejection fraction in patients with heart failure (HF) in Russian Federation. Cost-effectiveness model was developed for estimate the use of dapagliflozin as part of standard therapy in patients with HF regardless of ejection fraction is unknown. The calculation of costs was carried out in a mathematical model adapted to the conditions of Russian healthcare system by using Russian costs inputs and patient population characteristics. In the model, dapagliflozin therapy yielded a mean of 0.209 additional life-years compared with standard of care in 10 years horizon. The incremental cost of 1 additional life-year was 665,715 RUB, which does not exceed the threshold of willingness to pay 2,235,202 RUB. Thus, the intensification of chronic HF therapy with dapagliflozin is cost effective. The use of dapagliflozin in a cohort of 1000 target patients over 10 years will avoid 146 hospitalizations and 39 emergency visits due to HF, as well as prevent 32 deaths from cardiovascular diseases.

An economic evaluation of radiotherapy for patients with symptomatic Ledderhose disease

BackgroundEvidence for effectiveness of radiotherapy for Ledderhose disease was demonstrated in the LedRad-study. However, the health economic impact of Ledderhose disease is unclear. Therefore, an economic evaluation alongside the LedRad-study was planned. MethodsThe economic evaluation was performed as a cost-effectiveness and cost-utility analysis from the societal perspective. Primary outcome parameters were pain burden and Quality Adjusted Life Years (QALY), until 12 months after the end of treatment. Secondary analyses were performed with outcomes until 18 months. Incremental cost-effectiveness (ICER) and cost-utility ratios (ICUR) were calculated to express costs per unit improvement in pain burden and costs per QALY gained, for radiotherapy compared to sham-radiotherapy. Bootstrap replication was used to assess uncertainty surrounding the ratios and to construct cost-effectiveness acceptability curves for QALY gain. ResultsPrevious analysis showed a statistically significant improvement in pain- and QoL scores in favour of radiotherapy at 12 and 18 months. At these timepoints and excluding treatment costs, cumulative total costs were considerably lower in the radiotherapy group. The ICER until 12 months after treatment was 4987 euro per unit of pain burden reduction. The ICUR was 14249 euro per QALY gained. Most of the bootstrap replications were in the upper right quadrant, indicating that health gain can be achieved at higher costs. At increasing levels of willingness to pay for a gain in QALY, the probability of cost-utility gradually increased to approximately 85%. ConclusionsIn patients with symptomatic Ledderhose disease, radiotherapy, at a moderate threshold for willingness to pay, is cost-effective in terms of QoL gain.

Pharmacoeconomic analysis of the use of combinations of complex electrolyte compounds with citicoline in the treatment of patients with acute ischemic stroke in Ukraine

Ischemic stroke is a clinical syndrome of rapid development of signs of focal or global loss of brain function that lasts 24 hours or more or leads to death without other (nonvascular) causes. Cerebral stroke is one of the most severe forms of cerebrovascular disease. 
 A significant place in stroke pharmacotherapy is occupied by prescription drugs that increase the preservation of nervous tissue. Citicoline is an essential mediator in phosphatidylcholine biosynthesis, a major component of biological membranes.
 The study aimed to analyze the cost-effectiveness and budget impact on using of complex electrolyt compounds with citicoline combinations in treatment of patients with acute ischemic stroke in Ukraine.
 The cost analysis was based on a decision tree model developed for treatment within 28 days after an ischemic stroke, including the likelihood that a patient will need to undergo rehabilitation care in an out-patient or in-patient treatment.
 The cost of direct expenses was determined based on the results of the course of Neurocytin® in combination with standard therapy, compared to the use of standard therapy alone, which, according to the results of the modelled analysis, is 30 407.10 UAH and 28 171.43 UAH per 1 person, respectively. Due to performing a pharmacoeconomic analysis using the cost-effectiveness method, the cost-utility indicator was calculated, which for treatment with Neurocytin® is 47 142.79 UAH, and for standard therapy – 46 031.74 UAH. The calculated ICUR value is 68 996.36 UAH, which indicates that the technology of Neurocytin® in combination with standard therapy is more effective and more costly. The ratio of the potential threshold of «willingness to pay» and the ICUR value visually demonstrates that in terms of cost-effectiveness, the technology of Neurocytin® in combination with standard therapy is within the threshold of willingness to pay from the perspective of the state budget.
 Based on the budget impact analysis results, it was found that the cost of Scenario 3 (an annual 20% increase in the number of patients prescribed Neurocytin® in combination with standard therapy) will amount to 17.2 billion UAH.

Assessment of a SARS-CoV-2 population-wide rapid antigen testing in Italy: a modeling and economic analysis study.

This study aimed to compare the cost-effectiveness of coronavirus disease 2019 (COVID-19) mass testing, carried out in November 2020 in the Italian Bolzano/Südtirol province, to scenarios without mass testing in terms of hospitalizations averted and quality-adjusted life-year (QALYs) saved. We applied branching processes to estimate the effective reproduction number (Rt) and model scenarios with and without mass testing, assuming Rt = 0.9 and Rt = 0.95. We applied a bottom-up approach to estimate the costs of mass testing, with a mixture of bottom-up and top-down methodologies to estimate hospitalizations averted and incremental costs in case of non-intervention. Lastly, we estimated the incremental cost-effectiveness ratio (ICER), denoted by screening and related social costs, and hospitalization costs averted per outcome derived, hospitalizations averted and QALYs saved. The ICERs per QALY were €24249 under Rt = 0.9 and €4604 under Rt = 0.95, considering the official and estimated data on disease spread. The cost-effectiveness acceptability curves show that for the Rt = 0.9 scenario, at the maximum threshold willingness to pay the value of €40000, mass testing has an 80% probability of being cost-effective compared to no mass testing. Under the worst scenario (Rt = 0.95), at the willingness to pay threshold, mass testing has an almost 100% probability of being cost-effective. We provide evidence on the cost-effectiveness and potential impact of mass COVID-19 testing on a local healthcare system and community. Although the intervention is shown to be cost-effective, we believe the initiative should be carried out when there is initial rapid local disease transmission with a high Rt, as shown in our model.

Cost-effectiveness analysis of toripalimab plus chemotherapy as the first-line treatment in patients with advanced non-small cell lung cancer (NSCLC) without EGFR or ALK driver mutations from the Chinese perspective.

Objectives: The results of a CHOICE-1 study demonstrated the superior efficacy of toripalimab (anti-PD-1 antibody) plus chemotherapy for patients with advanced non-small cell lung cancer (NSCLC), with a manageable safety profile. This study was performed to evaluate the economic value of this treatment for this patient population from the Chinese payer's perspective. Materials and methods: Basic data were derived from the CHOICE-1 study. Markov models were developed to simulate the process of advanced NSCLC, including the progression-free survival (PFS), progressive disease (PD), and death in intention-to-treat (ITT) populations, as well as patients with squamous or non-squamous NSCLC. The cost was obtained from the local institution, and the value of utilities referred to previous studies. Monte Carlo simulations were performed to depict the probabilistic scatter plots of the incremental cost-effectiveness ratio (ICER) and acceptability curves, aiming to address the uncertainty of model inputs. Results: Compared with standard chemotherapy, toripalimab plus chemotherapy yields an ICER of $21,563 per quality-adjusted life year (QALY) in the ITT population. For patients with squamous NSCLC, comparing the combined therapy with chemotherapy led to an ICER of $18,369 per QALY, while the ICER was $24,754 per QALY in patients with non-squamous NSCLC. With the threshold of willingness to pay we set ($37,653 per QALY), toripalimab plus chemotherapy was cost-effective in these patient populations. Conclusion: For patients with advanced NSCLC, toripalimab plus chemotherapy was an optimal choice as first-line treatment, regardless of histology.

Economic evaluation of toripalimab plus chemotherapy compared with chemotherapy as first-line treatment for advanced esophageal squamous cell carcinoma in China

ABSTRACT Objectives The purpose of this study was to compare the cost-effectiveness of toripalimab versus Chemotherapy for patients with advanced esophageal squamous cell carcinoma (ESCC) from the perspective of the Chinese healthcare system. Methods A partitioned survival model was designed. Clinical data on survival was taken from the JUPITER-06 trials. Direct medical expenditures and utilities were gathered from published literature and a local database. One-way and probability sensitivity methods were used to evaluate the model’s robustness. Results Compared with chemotherapy alone, toripalimab offered an incremental cost of $8950.427 with an additional 0.294 QALYs, yielding an ICER of 30,443.629$/QALYs first-line therapy for advanced ESCC. The ICER was below the threshold of willingness to pay in China, indicating that the toripalimab group had a cost-effective advantage. Sensitivity analysis showed that the ICERs were most sensitive to the utility of PD, but all the parameters had no significant impact on the model’s outcomes. Conclusion Toripalimab may be a cost-effective first-line treatment choice in our research when compared to chemotherapy alone for patients with advanced ESCC.

Cost/effectiveness analysis of treatment options for the rehabilitation of the total edentulous mandible.

Several solutions are available for the rehabilitation of edentulous jaws. Each treatment option is characterised by specific advantages and drawbacks. The aim of this research was to perform a cost-effectiveness (CE) analysis of the main rehabilitative solutions of totally edentulous mandibles. Decision tree models were built using TreeAge Pro Healthcare 2021 software to compare the following strategies: Conventional Denture (CD), Overdenture retained by two implants (OD-2), Overdenture retained by a bar on two implants (ODbar), Overdenture retained by 4 mini-implants (ODmini) and Fixed denture supported by 4 implants (FD). Costs were estimated using data from public rate tables. Effectiveness measures were obtained from a meta-analysis of literature data, normalising the different scales in 0-1 range. A value of 30 000€ per 1 normalised utility points was set as threshold of willingness to pay (WTP). Probabilistic sensitivity analysis (PSA) with 1000 Monte Carlo Simulations was performed to characterise uncertainty. Total costs ranged between 1804,40€ for CD and 10 008,80€ for FD rehabilitations, with an effectiveness of 0,69 and 0,95 normalised points (0-1 scale) for the two solutions. The ODbar resulted to be the most CE strategy at the established WTP value, with the highest Net Monetary Benefit (22 001,20€), followed by the OD-2 rehabilitation (21 866,80€). PSA analysis confirmed the dominance of OD-2 and ODbar strategies, confirming a net separation from the other alternatives. OD stabilised by 2 implants could represent a good rehabilitative solution for patients with edentulous mandible, being a good trade-off in terms of costs and effectiveness. Nevertheless, a standardised measure of oral health-related quality of life is needed to obtain more reliable results.

Сost-effectiveness of pentavalent rotavirus vaccination in the Russian Federation

One of the main causes of acute gastroenteritis in children under 5 years of age is rotavirus infection (RVI). Vaccines against RVI significantly reduce the incidence. Aim. To evaluate the cost-effectiveness of mass vaccination of children with a 5-valent RVI vaccine in the Russian Federation. Materials and methods. The assessment was carried out using modeling based on published data on the effectiveness of the vaccine and epidemiological indicators in the Russian Federation. The analysis was carried out from the perspective of the health care system and society as a whole with a 5-year horizon. The cost of RVI therapy corresponded to the compulsory health insurance tariffs for St. Petersburg for 2022, the price of 1 dose of the vaccine was the registered price, including VAT. Costs and life expectancy, taking into account quality, were discounted at 3.5 % per year. Results. Given the assumptions made, routine vaccination will prevent an average of 468,637 cases of RVI over 5 years. Avoided direct medical costs, i. e. RVI treatment costs will amount to 53,4 %, and lost income due to temporary disability – 46,6 % of the total avoided costs. At the same time, the volume of avoided costs is 61,4 % due to a decrease in morbidity in the vaccinated population, and 38.6 % due to the development of a indirect effect. The predicted avoided costs per 1 vaccinated person is 2,975 thousand rubles. From a societal perspective, the cost-effectiveness of the Rota-V-Aid vaccine will be 364,813 thousand rubles / QALY (quality-adjusted life year), and from a healthcare perspective – 1726,399 thousand rubles / QALY. Thus, in both cases, the cost-effectiveness of RVI vaccination will not exceed the generally accepted threshold of willingness to pay, equal to three times the gross domestic product per capita in the Russian Federation (according to data for 2021 – ~2,7 million rubles). The predicted cost-effectiveness of selective vaccination is significantly lower than that of mass vaccination. Conclusions. Mass vaccination of children with a 5-valent vaccine against RVI will not only reduce the incidence in the Russian Federation, but, taking into account the assumptions made, can also be considered as a cost-effective intervention.

Cost-effectiveness analysis of pembrolizumab plus chemotherapy versus chemotherapy as the first-line treatment for advanced esophageal cancer.

The KEYNOTE-590 trial showed that individuals with advanced esophageal cancer who received Pembrolizumab in combination with chemotherapy as a first-line regimen achieved a significant extension of survival. However, this treatment option increases the financial burden on patients and the economic benefits remain to be further evaluated. A Markov model was used to simulate 10-year survival of patients with esophageal cancer from the perspective of United States (US) Medicare payers. We evaluated the economics of Pembrolizumab plus chemotherapy in the PD-L1 positive score (CPS ≥10) and any PD-L1 expression groups, respectively. We estimated total costs, quality-adjusted life years (QALYs), and calculated incremental cost effectiveness ratios (ICERs). Sensitivity analyses were conducted to explore the impact of uncertainties on the results. Subgroup analysis was also performed. The analysis results showed that the ICER for pembrolizumab plus chemotherapy versus chemotherapy alone was $293,513.17/QALYs in the any PD-L1 expression group. This exceeded the threshold of willingness to pay ($150,000/QALYs). ICERs were most sensitive to the cost of pembrolizumab and the ICERs exceeded $150,000/QALYs in all subgroups. Evidence suggests that first-line pembrolizumab in combination with chemotherapy is not a cost-effective option for advanced esophageal cancer in the US, regardless of PD-L1 expression status.

Discrete Event Simulation Model for Cost-Effectiveness Evaluation of Screening for Asymptomatic Patients with Lower Extremity Arterial Disease.

Lower limb ischemic disease (LEAD) affects a significant portion of the population, with most patients being asymptomatic. Patient screening is necessary because LEAD patients have an increased risk of occurrence of other cardiovascular events and manifestations of disease, in terms of leg symptoms such as intermittent claudication, critical limb ischemia, or amputation. The aim of this work was to evaluate the cost-effectiveness of screening using ABI diagnostics in asymptomatic patients and its impact on limb symptoms associated with LEAD. A discrete event simulation model was created to capture lifetime costs and effects. Costs were calculated from the perspective of the health care payer, and the effects were calculated as QALYs. A cost-effectiveness analysis was performed to compare ABI screening examination and the situation without such screening. A probabilistic sensitivity analysis and scenario analysis were carried out to evaluate the robustness of the results. In the basic setting, the screening intervention was a more expensive intervention, at a cost of CZK 174,010, compared to CZK 70,177 for the strategy without screening. The benefits of screening were estimated at 14.73 QALYs, with 14.46 QALYs without screening. The final ICER value of CZK 389,738 per QALY is below the willingness to pay threshold. Likewise, the results of the probabilistic sensitivity analysis and of the scenario analysis were below the threshold of willingness to pay, thus confirming the robustness of the results. In conclusion, ABI screening appears to be a cost-effective strategy for asymptomatic patients aged 50 years when compared to the no-screening option.

Economic evaluation of margetuximab vs. trastuzumab for pretreated ERBB2-positive advanced breast cancer in the US and China.

ObjectiveTo assess the economic evaluation of margetuximab plus chemotherapy over trastuzumab plus chemotherapy for women with pretreated ERBB2-positive advanced breast cancer in the United States (US) and China.MethodsBased on the SOPHIA trial, a three-state Markov model was developed to compare the cost and efficacy of margetuximab to trastuzumab for previously treated women with ERBB2-positive advanced breast cancer. The model inputs were derived from existing literature and the US life table. Primary outcomes included lifetime costs in US dollars, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER). Deterministic and probabilistic sensitivity analyses were conducted to evaluate the impact of uncertainty.ResultsThe base case analyses demonstrated that margetuximab plus chemotherapy had an increasing cost of $68,132 and $20,540 over trastuzumab plus chemotherapy in the US and China, respectively, with a gain of 0.11 and 0.09 QALYs both favored margetuximab. The ICERs for two treatment strategies were $260,176 in the US and $630,777 in China, resulting in a poor cost-effectiveness at their respective threshold of willingness to play. One-way sensitivity analyses showed that the results to be most sensitive to the price of margetuximab and that of trastuzumab. And an 11 and 82% price reduction of margetuximab would make this regimen cost-effective in the US and China, respectively.ConclusionIn the US and China, margetuximab plus chemotherapy is not likely to be cost-effective for women with pretreated ERBB2-positive advanced breast cancer, whereas price reduction effectively improves insufficient cost-effectiveness.

Cost–effectiveness of ensartinib for patients with anaplastic lymphoma kinase-positive non-small-cell lung cancer in China

Background: Crizotinib and ensartinib improved survival in patients with ALK arrangement non-small-cell lung cancer (NSCLC); however, the economic outcomes of using ensartinib versus crizotinib are still unclear. Aim: The objective of this study was to assess the cost-effectiveness of ensartinib versus crizotinib for ALK-positive NSCLCpatients from the perspective of China's healthcare system. Methods: A partitioned survival model with threehealth states (stable, progressiveand death) was developed. Survival data were obtained from published eXalt3 clinical trials of ensartinib versescrizotinib for patients with anaplastic lymphoma kinase-positive non-small-celllung cancer. Parametric models were used to extrapolate outcomes beyond the trial period. The drug cost comes from the local drug procurement platform. Other costs and utility values were obtained from published literature, and one-way and probabilistic sensitivity analyses were carried out to determine the robustness of the model outcomes. Results: In the whole life cycle, the average annual cost of ensatinib was US$77,636.63, and utility value was 5.5 quality adjusted life years (QALYs). Patients receiving crizotinib had 3.315QALYsand US$32,935.88 costs over the same time horizon. The incremental cost utility ratio is US$19,810.55/QALYs. In 2021, the per capita GDP of China is US$12,721.33, and the incremental cost utility is lower than the threshold of willingness to payUS$38,163.99. Conclusion: Compared with crizotinib, ensatinib is economical in the treatment of ALK-positiveNSCLCand should be promoted.

Cost-effectiveness of osimertinib versus placebo in resected EGFR-mutated non-small cell lung cancer in China.

We aim to assess whether osimertinib postoperative adjuvant therapy, compared with placebo, is cost-effective in China. We set up the Markov model that contains three health states over a 20-year period. Data were collected from the ADAURA trial that included transition probabilities and safety data. Through the analysis of literature and local charges, we explore both the cost and utility values. Sensitivity analyses were employed using TreeAge Pro software to access model stability. Patients in the osimertinib group had 1.46 more Quality-adjusted Life Years (8.45 QALYs vs 6.99 QALYs) than the placebo group at an incremental cost of $14098.51($39962.99 vs $25864.48). Compared with the placebo group, the treatment strategy with osimertinib postoperative adjuvant therapy had an incremental cost-effectiveness ratio of $9661.97/QALY. The probability of the osimertinib-assisted therapy strategy being cost-effective will reach 100% if the threshold of willingness to pay is above $15,000/QALY. From the perspective of the Chinese Healthcare System, the treatment strategy with osimertinib postoperative adjuvant therapy is more cost-effective than the placebo strategy.

Predictors of Achieving the Maximal Outcome Improvement Threshold for Willingness to Undergo Revision Hip Arthroscopy

Background: The maximal outcome improvement threshold for willingness to undergo revision hip arthroscopy (MOWT) has not been defined yet. Purpose: To determine the percentage MOWT in patients who underwent revision hip arthroscopy and to identify predictors of achieving the MOWT. Study Design: Case-control study; Level of evidence, 3. Methods: An anchor question was provided to patients who underwent revision hip arthroscopy between April 2008 and June 2020 who returned for follow-up between August 2019 and June 2021 at one institution. Patients were included if they underwent revision hip arthroscopy, had answered the anchor question, and had baseline and postoperative minimum 1-year follow-up scores for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and the visual analog scale (VAS) for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia, previous hip conditions, or unwillingness to participate. Receiver operating characteristic analysis was used to determine the MOWT. Multivariate logistic regression was used to determine intraoperative predictors of achieving the MOWT. Results: In total, 153 patients (163 hips) were included, with 117 female hips (71.8%), a mean patient age of 34.3 ± 12.4 years, and an average follow-up time of 61.6 ± 42.7 months. It was determined that 77.3% of the patients reported that they would choose to undergo the revision hip arthroscopy again. The MOWT for the mHHS, NAHS, and VAS was 43.1%, 53%, and 33.4%, respectively. The probability of choosing to undergo revision surgery if the MOWT was achieved was 77.5%, 77.6%, and 79.2%, for the mHHS, NAHS, and VAS, respectively. Patients with residual cam-type morphology, which was addressed during the revision, were 2.3 times more likely to achieve the MOWT for the VAS (P = .014). Conclusion: Patients who improved 43.1%, 53%, and 33.4% of their MOWT for the mHHS, NAHS, and VAS, respectively, were likely to be willing to undergo revision hip arthroscopy again. Moreover, the presence of residual cam-type femoroacetabular impingement morphology before their revision surgery was identified as a predictor to achieve the MOWT for the VAS.

Cost-Effectiveness of Posaconazole vs. First-Generation Triazoles for the Prevention of Invasive Fungal Infections Among High-Risk Patients With Hematological Malignancies in China.

BackgroundPosaconazole is confirmed to be more effective for preventing invasive fungal infections (IFIs) than first-generation triazoles (fluconazole and itraconazole), but its economic value has not been comprehensively evaluated in China. This study compared the cost-effectiveness of these two antifungal prophylaxis regimens in hematological-malignancy patients at high risk for IFIs from the Chinese healthcare perspective.MethodsA hybrid decision tree and Markov model were built using published data to estimate the total costs and quality-adjusted life-years (QALYs) of antifungal prophylaxis with posaconazole oral suspension and first-generation triazoles. Regimens with an incremental cost-effectiveness ratio (ICER) lower than the threshold of willingness to pay (WTP) were considered cost-effective. One-way and probabilistic sensitivity analyses were performed to assess model robustness. The regional imbalance of economic development and the tablet formulation of posaconazole were considered in the scenario analyses.ResultsIn the base-case analysis, posaconazole oral suspension provided an additional 0.109 QALYs at an incremental cost of $954.7, yielding an ICER of $8,784.4/QALY, below the national WTP threshold of $31,315/QALY. One-way and probabilistic sensitivity analyses showed that the results were robust. Scenario analyses showed that the base-case ICER was consistently below the WTP thresholds of all 31 Chinese provinces, with the likelihood of posaconazole being cost-effectiveness ranging from 78.1 to 99.0%. When the posaconazole oral suspension was replaced by the tablet formulation, the ICER increased to $29,214.1/QALY, still below the national WTP threshold and WTP thresholds of 12 provinces.ConclusionsPosaconazole oral suspension is a highly cost-effective regimen for preventing IFI in high-risk hematological-malignancy patients from the Chinese healthcare perspective. Posaconazole tablets may also be considered in some high-income regions of China.

Economic Evaluation of Nemonoxacin, Moxifloxacin and Levofloxacin in the Treatment of Early Community-Acquired Pneumonia with Possible Pulmonary Tuberculosis.

The Chinese community-acquired pneumonia (CAP) Diagnosis and Treatment Guideline 2020 recommends quinolone antibiotics as the initial empirical treatment options for CAP. However, patients with pulmonary tuberculosis (PTB) are often misdiagnosed with CAP because of the similarity of symptoms. Moxifloxacin and levofloxacin have inhibitory effects on mycobacterium tuberculosis as compared with nemonoxacin, resulting in delayed diagnosis of PTB. Hence, the aim of this study is to compare the cost-effectiveness of nemonoxacin, moxifloxacin and levofloxacin in the treatment of CAP and to determine the value of these treatments in the differential diagnosis of PTB. Primary efficacy data were collected from phase II-III randomized, double-blind, multi-center clinical trials comparing nemonoxacin to moxifloxacin (CTR20130195) and nemonoxacin to levofloxacin (CTR20140439) for the treatment of Chinese CAP patients. A decision tree was constructed to compare the cost-utility among three groups under the perspective of healthcare system. The threshold for willingness to pay (WTP) is 1–3 times GDP per capita ($11,174–33,521). Scenarios including efficacy and cost for CAP patients with a total of 6% undifferentiated PTB. Sensitivity and scenario analyses were performed to test the robustness of basic analysis. The costs of nemonoxacin, moxifloxacin, and levofloxacin were $903.72, $1053.59, and $1212.06 and the outcomes were 188.7, 188.8, and 188.5 quality-adjusted life days (QALD), respectively. Nemonoxacin and moxifloxacin were dominant compared with levofloxacin, and the ICER of moxifloxacin compared with nemonoxacin was $551,643, which was much greater than WTP; therefore, nemonoxacin was the most cost-effective option. Regarding patients with PTB who were misdiagnosed with CAP, taking nemonoxacin could save $290.76 and $205.51 when compared with moxifloxacin and levofloxacin and resulted in a gain of 2.83 QALDs. Our findings demonstrate that nemonoxacin is the more economical compared with moxifloxacin and levofloxacin, and non-fluoroquinolone antibiotics are cost-saving and utility-increasing compared to fluoroquinolones in the differential diagnosis of PTB, which can help healthcare system in making optimal policies and help clinicians in the medication of patients.
