ObjectiveTo systematically review the economic evaluation research of anti-novel coronavirus infection drugs at home and abroad, so as to promote clinical rational drug use. MethodsThe PubMed, Cochrane Library, EMbase, Web of Science, INAHTA, SinoMed, WanFang Data, and CNKI databases were systematically searched from January 1, 2020 to March 25, 2023, to collect economic evaluation studies related to anti-novel coronavirus infection drugs. ResultsA total of 22 articles were included, among which 11 studies were conducted from the perspective of health system, and most of the studies performed cost estimation on direct medical costs. The overall compliance rate of the included studies ranged from 42% to 70%, with deficiencies in model setting, incomplete uncertainty analysis, and lack of stakeholder participation. The results showed that immunotherapy drugs (Dexamethasone, Tocilizumab), neutralizing antibody (REGEN-COV antibody), small molecule drugs (Baricitinib, Nirmatrelvir/Ritonavir, Molnupiravir, Favipiravir) and statin were cost-effective. There was some variation in the results of the economic evaluation of Remdesivir. ConclusionAt present, there are few studies on the economic evaluation of drug interventions in COVID-19. Existing studies have pointed out that most drug interventions are cost-effective. It is suggested that more standardized pharmacoeconomic evaluation studies based on the actual situation of China epidemic should be carried out in the future.
Medicine is a very important health resource in China. Although numerous efforts are paid to pre-marketed medicines, little is done to address practical problems in marketed medicines. The rational use and allocation of marketed medicines remain a major concern for decision-makers in China. It has been recognized that economic evaluation is an efficient tool for prioritizing the choice, and optimizing the use of medicines. This paper has explored the methods and principles for conducting economic evaluation of marketed medicines. Different strategies will be adopted for economic evidence for marketed medicines in terms of adequacy and sufficiency.However, a standard study pathway should be applied in economic evaluation of marketed medicines. Besides, the aspects for developing economic framework and the methods for reviewing existing economic evidence are also introduced in this paper, particularly, for marketed medicines within the same therapeutic group.
Objective To systematically review the health economic evaluations of using long-term rhythm-control antiarrhythmic drugs (AAD) for patients with paroxysmal or persistent atrial fibrillation (AF). Methods Databases including PubMed, EMbase, Scopus, CNKI, SinoMed, WanFang Data, and official websites of well-established health technology assessment (HTA) institutions were electronically searched to present the economic evaluations of AAD and the recommendations of HTA institutions based on drug economy from inception to April 23rd, 2022. Two reviewers independently screened the literature, extracted data and systematic review was then performed. Results A total of 19 studies were included, including 11 cost-effectiveness or cost-utility analysis studies and 8 official documents from HTA institutions. Only 5 (45.5%) economic evaluations were of relatively high quality, and English language studies were of higher quality than Chinese language studies ones. The included studies lacked elements that CHEERS 2022 concerns, such as health economics analysis plans, equity and distributional effects, engagement with patients and other stakeholders and the impact on the study. Dronedarone and amiodarone were the main focus of the evaluation, and the study results showed that dronedarone was cost-effective compared with other drugs in different study designs and national settings. However, there were differences between the recommendations of HTA agencies and the results of economic evaluation studies. Conclusion The completeness of health economics evaluations needs to be improved, along with the quality of clinical evidence in the field of AF-AAD for Chinese patients. Additionally, the informational value of drugs should be thoroughly investigated through budget impact analysis and distributional cost-effectiveness analysis to provide evidence of high-quality studies for decision-makers in China.
Objective To evaluate the cost-effectiveness of chemotherapy in children with newly diagnosed Hodgkin lymphoma at low-, intermediate-, and high-risk. Methods From the perspective of health system, a decision-tree model was designed for cost-effectiveness analysis. The chemotherapy regimens of low-risk group included OEPA (vincristine, etoposide, prednisone, doxorubicin), AV-PC (doxorubicin, vincristine, prednisone, cyclophosphamide), and ABVD (doxorubicin, bleomycin, vincristine, dacarbazine); intermediate-risk group included OEPA, ABVE-PC (doxorubicin, bleomycin, vincristine, etoposide, prednisone, cyclophosphamide) and ABVD; high-risk group included OEPA, ABVE-PC, ABVD and BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone). The effectiveness and cost parameters were derived from the event-free survival rate reported in the literature, the drug linked reference price in Sichuan province, and treatment price of medical institutions. Univariate and probabilistic sensitivity analysis were performed to explore the impact of uncertainty. Results In the low-risk group, compared with AV-PC, the incremental cost-effectiveness ratios (ICER) of OEPA and ABVD were 80 700 yuan and 108 799 yuan, respectively. In the intermediate-risk group, compared with OEPA, the ICER of ABVE-PC and ABVD were −17 737 yuan and −4 701 yuan respectively. In the high-risk group, compared with ABVE-PC, the ICER of OEPA, ABVD and BEACOPP were 149 262, 472 090 and 64 652 yuan, respectively. Univariate sensitivity analysis showed that in low-risk group, the most influential factors were cost of OEPA and cost of ABVD; in moderate-risk group were cost of ABVE-PC and cost of OEPA; in the high-risk group were cost of OEPA, cost of ABVD, and cost of BEACOPP, respectively. The results of probabilistic sensitivity analysis are basically consistent with those of the main analysis. Conclusion If China's per capita gross domestic product in 2023 (89 358 yuan) was used as the willingness-to-pay (WTP) threshold, OEPA in the low-risk group, OEPA in the intermediate-risk group and BEACOPP in the high-risk group are cost-effective.
ObjectiveTo assess the health effectiveness, cost and cost effectiveness of different oral anticoagulation (OAT) therapies in China, including warfarin plus international normalized ratio (INR) test in hospital labs (Lab test), warfarin plus patient self-management (PSM) with point of care device, and novel anticoagulant (Dabigatran) alone. MethodsA Markov model containing four states (no complication, hemorrhagic event, thrombotic event and death) was developed to account for long-term cost and outcomes of warfarin/novel anticoagulant users including atrial fibrillation patients and deep venous thrombosis patients. Direct medical cost was taken into consideration, covering expenses of drugs, OAT monitoring and complication management. Both clinical and cost parameters were mainly derived from literatures. ResultsCompared with hospital lab test, the PSM pattern obtained a prolonged 8.48 years and 5.08 QALYs with the larger amount of cost, CNY 47 482. The incremental cost-effectiveness ratio (ICER) of PSM versus hospital lab test came to CNY 19 240 per QALY gained, lower than GDP China per capita in 2014 (CNY 46 628). And the novel anticoagulant pattern was dominated by PSM pattern due to shortened QALYs while increased cost. The sensitivity analysis demonstrated the results were not sensitive to main indicators, including utility in different health status, complication probability, and disease management cost. ConclusionPSM can generate more QALYs by reducing the risk of major thrombotic and bleeding events with acceptable incremental cost, which turns to be the most cost effective way among the 3 patterns and demonstrates promising future in OAT management.
Objective To systematically review the health economic evaluation studies of medicines for the treatment of acute myeloid leukemia (AML). MethodsThe PubMed, EMbase, Cochrane Library, CBM, CNKI, and WanFang Data, as well as the CRD database specifically for health economics were electronically searched from inception to June 2022, and related journals in the field of health economics and the websites of HTA institutions in various countries were manually searched. The quality of the studies was assessed using the CHEERS checklist. The basic characteristics of health economics evaluation publications were summarized, the quality of model structures and methodologies was assessed and economic evaluation results were compared among different treatments. Results A total of 17 studies were included, and cost-effectiveness analyses were conducted from the perspectives of the health system, patients, the whole society, and medical insurance payers. The economic evaluation models were relatively unified, but there were differences in methods and results reporting, and the quality needed to be improved. The research objects were mainly the comparison of hypomethylating agents, targeted medicine and traditional chemotherapy regimens, as well as the comparison of different chemotherapy combinations and different drug dosages. Conclusion Real-world studies are mainly focused on traditional chemotherapy regimens, and model-based health economic evaluations, such as Markov models, are more frequently applied to newly developed targeted drugs and demethylation drugs. Among all treatments, the chemotherapy regimens including cytarabine, midostaurin, and decitabine are found to be more cost-effective.
ObjectiveTo analyze the cost and performance of five methods for detection of carbapenemase-producing Enterobacteriaceae (CPE), including PCR (method A), Carba NP test (method B), ultraviolet spectrophotometry (method C), modified carbapenem inactivation method (mCIM, method D), and loop-mediated isothermal amplification (LAMP, method E).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were searched using the computer regarding literature on detection of CPE with the same or similar designs, same objectives, and independent results. The search was limited between May 2009 and May 2019. Data on the cost and detection performance of all five methods were extracted, and the four special indexes for laboratory tests, such as sensitivity, specificity, simplicity, and rapidity in the utility were quantified as specific values; subsequently, the cost-effective analysis (CEA), cost-utility analysis (CUA), and multi-attribute utility theory (MAUT) in the detection economic analysis were used to conduct health economics evaluation of five detection methods for CPE.ResultsThe cost of methods A, B, C, D and E were 210.00 yuan, 22.00 yuan, 10.50 yuan, 6.00 yuan, and 60.00 yuan, respectively. The C/E of CEA for the above five methods were 210.00, 22.96, 10.66, 6.14, and 60.00, respectively. The C/U of CUA for the above five methods were 302.16, 32.13, 19.30, 11.13, and 80.00, respectively. The MAUT value of the above five methods were 42.56, 5.00, 2.54, 1.63, and 12.56, respectively.ConclusionIn terms of CEA, CUA, and MAUT, the method D was the highest in economic value, which usually can be used as a routine method for detecting CPE, but it needs a long procedure time; thus, the method E can be used for rapid detection when clinical severe infection occurred, which is superior in both cost-effectiveness and rapidity.
ObjectiveTo systematically review the status of economic evaluation of liver cancer screening in China, so as to provide reference for further studies.MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data, CBM and VIP databases were searched to collect economic evaluation studies of liver cancer screening in China from inception to December, 2017. Two reviewers independently screened literature, extracted data and conducted descriptive analysis of basic characteristics, methods of economic evaluation and main results as well as quality and uniformity of reporting.ResultsA total of 5 studies were included. Among them, the starting age of screening were found to be 35 to 45 years old; α-fetoprotein (AFP) testing and ultrasound examination combined procedure and screening interval of every 6 months were mostly evaluated. The quality of the 5 studies was satisfactory, and the uniformity of reporting was relatively acceptable, with a median score of 78% (range: 60% ~ 78%). Two population-based studies reported cost per liver cancer detected (44 thousand and 575 thousand yuan). Three studies reported cost-effectiveness ratio(CER) based on life year saved (LYS) and quality adjusted life year (QALY). Among these results, only 1 study from mainland China reported CER based on LYS (1 775 yuan), and the calculated ratio of CER to local GDP per capita was estimated as 0.1, while 2 studies from Taiwan province reported 4 CERs, and the ratios of CER to local GDP per capita ranged from 1.0 to 2.2.ConclusionsInformation from liver cancer endemic areas such as Taiwan province indicates promising cost-effectiveness to conduct liver cancer screening in local general population, while data from mainland suggests that conducting liver cancer screening combining AFP and ultrasound in high-risk population will be cost-effective, however only supported by 1 regional study. This needs to be verified by further economic evaluations based on randomized controlled trials or cohort studies as well as health economic evaluations.
Economic evaluation used alongside clinical trials has become a hot spot in the development of clinical studies. The definition and classification of the cost were introduced in this article. The ways to conduct cost analysis in clinical trials were introduced systematically, including the identification, collection and analysis of the data of costs, and the concern of the analysis.
