Purpose
Induction immunosuppression therapy is used to support optimal outcomes in kidney transplantation. This study was to assess the cost-effectiveness of rabbit antithymocyte globulin (r-ATG) versus ATG-Fresenius (ATG-F) in kidney transplantation in the Chinese setting from the perspective of the health care payer.Methods
A 2-part survival model was developed, consisting of a short-term part and a long-term part. The short-term part analyzed the first year, using the decision tree, and consisted of the functioning transplant, acute rejection (AR), delayed graft function (DGF), dialysis, and death health states. The long-term part analyzed 2 to 5 years, using Markov model, and consisted of the functioning transplant, chronic dysfunction, recurring primary disease, dialysis, and death health states, with capture of the association between DGF and graft loss. Costs, including drug acquisition and other direct medical costs, were derived from China IQVIA database (formerly known as IMS) hospitaldatabase, chart review, and physician interviews. Clinical outcomes and utility were retrieved from published literature. The model calculated quality-adjusted life-years (QALYs) and total costs per patient. Costs and QALYs were discounted at an annual rate of 3.5%. Univariate sensitivity analysis and probability sensitivity analysis (PSA) were conducted to assess the impact of uncertainty of the variables on the results.Findings
Patients who received r-ATG had more clinical effectiveness than patients who received ATG-F mainly because of less AR, DGF, and dialysis. The incremental QALY was 0.01 over a 1-year time horizon and 0.0496 over a 5-year time horizon. R-ATG and ATG-F drug costs were ¥10,783 and ¥8409, respectively. However, the total treatment costs of the r-ATG arm were lower than the ATG-F arm because of lower costs related to DGF, AR, dialysis, and adverse events. In total, r-ATG saved ¥5423 over the 1-year and ¥7042 over the 5-year time horizon. R-ATG was dominant with lower total direct medical costs and higher QALYs compared with ATG-F. Both univariate sensitivity analysis and PSA found the robustness of the model results. PSA results indicated that r-ATG was cost-effective compared with ATG-F in 86.81% of the simulations, considering <3 times the gross domestic product per capita as the threshold.Implications
From the perspective of the health care payer, r-ATG should be considered as the preferred treatment agent for induction therapy for Chinese patients undergoing kidney transplantation because of its lower overall medical costs and greater QALYs gained compared with ATG-F. The study was limited by lack of long-term efficacy data among the Chinese population and lack of comprehensive real-world higher quality costs data. 相似文献994.
Purpose
Monotherapy with either aspirin or clopidogrel is recommended for long-term use after discontinuation of dual-antiplatelet therapy (DAPT) for acute coronary syndrome (ACS) management after percutaneous coronary intervention (PCI). The present study is to evaluate the cost-effectiveness of clopidogrel versus aspirin after 12-month DAPT for patients with ACS who underwent PCI in China.Methods
A 2-part model was developed to estimate the cost-effectiveness of clopidogrel compared with aspirin. The short-term part was a decision tree that included health states such as myocardial infarction (MI), stroke, MI and stroke, cardiovascular death, and death from other causes with a treatment horizon of 1 year (base case), 2 years or 3 years after 12-month DAPT. Major bleeding was included. The long-term (lifetime) part was a Markov model that included different health states such as MI, after MI, stroke, after stroke, and death. Drug acquisition cost and other direct medical costs were based on pricing records, literature, and expert panels. Clinical outcomes and utilities were based on literature. The model output included incremental cost-effectiveness ratio of quality-adjusted life-years (QALYs) and total costs per patient. Both 1-way sensitivity analysis and probabilistic sensitivity analysis (PSA) were conducted.Findings
In the base–case scenario, the total costs of the treatment with clopidogrel and aspirin were ¥12,590 ($1849/€1590) and ¥10,642 ($1563/€1344), respectively; the total QALYs of the 2 patient populations were 9.7341 and 9.6894, respectively. The incremental cost-effectiveness ratio of ¥43,593 ($6402/€5515) per QALY gained was lower than 3 times of gross domestic product (GDP) per capita in China (¥161,940, $23,786/€20,449). Both 1-way sensitivity analysis and PSA confirmed the robustness of the results. PSA results indicated that clopidogrel was cost effective versus aspirin in 80.5% of the simulations, considering >3 times the GDP per capita as the threshold. Results in other scenarios (clopidogrel or aspirin for 2 or 3 years after 12-month DAPT) also indicated that clopidogrel was more cost effective than aspirin for patients with ACS after 12-month DAPT.Implications
Compared with aspirin monotherapy, clopidogrel monotherapy for 1 year after 12-month DAPT was cost effective for patients with ACS who underwent PCI in China. Furthermore, when the duration of clopidogrel the monotherapy extended up to 3 years, clopidogrel was still cost effective compared with aspirin. The study was limited by lack of high-quality efficacy data among the Chinese population. 相似文献995.
