Cost-effectiveness

成本效益
  • 文章类型: Journal Article
    自2017年以来,免疫检查点抑制剂(ICIs)已用于治疗晚期肝细胞癌(HCC)或不可切除的HCC。但是他们在国家医疗保险计划中的采用仍然有限。成本效益证据可以帮助告知治疗决策。本系统综述旨在提供ICIs作为晚期HCC治疗方法的经济评估的重要摘要,并确定关键驱动因素(PROSPERO2023:CRD42023417391)。使用的数据库包括Scopus,WebofScience,PubMed,Embase,和CochraneCentral.包括ICI治疗晚期HCC的经济学评价。研究由两个人筛选。在确定的898条记录中,共包括17篇文章。目前的证据表明ICIs,包括阿替珠单抗加贝伐单抗,sintilimab加贝伐单抗/贝伐单抗生物仿制药,Nivolumab,camrelizumab加rivoceranib,pembrolizumab加lenvatinib,tislelizumab,durvalumab,卡博替尼联合阿特珠单抗,与酪氨酸激酶抑制剂或其他ICI相比,可能不具成本效益。最有影响的参数是抗癌药物的价格,无进展生存期和总生存期的风险比,和健康状态的效用。我们的评论表明,ICI不是晚期HCC的成本效益高的干预措施。虽然ICI可以显着提高晚期HCC患者的生存率,在采用新疗法之前,决策者应考虑经济评估的结果和可负担性。
    Since 2017, immune checkpoint inhibitors (ICIs) have been available for the treatment of advanced hepatocellular carcinoma (HCC) or unresectable HCC, but their adoption into national medical insurance programs is still limited. Cost-effectiveness evidence can help to inform treatment decisions. This systematic review aimed to provide a critical summary of economic evaluations of ICIs as a treatment for advanced HCC and identify key drivers (PROSPERO 2023: CRD42023417391). The databases used included Scopus, Web of Science, PubMed, Embase, and Cochrane Central. Economic evaluations of ICIs for the treatment of advanced HCC were included. Studies were screened by two people. Of the 898 records identified, 17 articles were included. The current evidence showed that ICIs, including atezolizumab plus bevacizumab, sintilimab plus bevacizumab/bevacizumab biosimilar, nivolumab, camrelizumab plus rivoceranib, pembrolizumab plus lenvatinib, tislelizumab, durvalumab, and cabozantinib plus atezolizumab, are probably not cost-effective in comparison with tyrosine kinase inhibitors or other ICIs. The most influential parameters were price of anticancer drugs, hazard ratios for progression-free survival and overall survival, and utility for health statest. Our review demonstrated that ICIs were not a cost-effective intervention in advanced HCC. Although ICIs can significantly enhance the survival of patients with advanced HCC, decision-makers should consider the findings of economic evaluations and affordability before adoption of new therapies.

    在双盲中,第三阶段,安慰剂对照Ruby随机临床试验,在原发性晚期或复发性子宫内膜癌(EC)患者中,多司他单抗联合卡铂-紫杉醇可显著提高生存率.我们从美国付款人的角度对这些按错配修复缺陷(dMMR)和错配修复熟练(pMMR)亚组分层的患者进行了dastarlimab联合化疗的成本效益分析。
    基于RUBY试验,采用具有三种状态的马尔可夫模型来模拟接受dastarlimab联合化疗或化疗的患者。质量调整寿命年(QALYs),终身成本,和增量成本效益比(ICER)的计算与支付意愿(WTP)阈值$150,000/QALY。进行了单变量和概率敏感性分析以探索模型的稳健性。
    在dMMREC中,与单纯化疗相比,dastarlimab和化疗的组合增加了5.48个QALYs,增加了330,747美元,导致每QALY的ICER为60,349.30美元。在pMMREC中,额外增加了1.51个QALY,额外成本为265,148美元,每QALY产生175,788.47美元的ICER。dosstarlimab有15.2%的折扣,在pMMREC中,ICER降至每QALY150,000美元。单变量敏感性分析显示,dosstarlimab的成本,无进展生存期(PFS)的效用,和进行性疾病(PD)对结局的影响最显著.概率敏感性分析显示,dMMREC的WTP阈值为$150,000/QALY时,dosstarlimab有100%的可能性被认为对患者具有成本效益。而pMMREC的可能性仅为0.5%。
    从美国付款人的角度来看,Dostarlimab联合化疗对原发性晚期或复发性dMMREC具有成本效益,每个QALY的WTP阈值为150,000美元,但不是PMMREC。降低dosstarlimab的价格可能会提高pMMREC治疗的成本效益。
    UNASSIGNED: In the double-blind, phase III, placebo-controlled RUBY randomized clinical trial, dostarlimab plus carboplatin-paclitaxel significantly increased survival among patients with primary advanced or recurrent endometrial cancer (EC). We conducted a cost-effectiveness analysis of dostarlimab in combination with chemotherapy in these patients stratified by mismatch repair-deficient (dMMR) and mismatch repair-proficient (pMMR) subgroups from the perspective of a United States payer.
    UNASSIGNED: A Markov model with three states was employed to simulate patients who were administered either dostarlimab in combination with chemotherapy or chemotherapy based on the RUBY trial. Quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratio (ICER) were calculated with a willingness-to-pay (WTP) threshold of $150,000 per QALY. Both univariate and probabilistic sensitivity analyses were carried out to explore the robustness of the model.
    UNASSIGNED: In dMMR EC, the combination of dostarlimab and chemotherapy achieved an additional 5.48 QALYs at an incremental cost of $330,747 compared to chemotherapy alone, resulting in an ICER of $60,349.30 per QALY. In pMMR EC, there were 1.51 additional QALYs gained at an extra cost of $265,148, yielding an ICER of $175,788.47 per QALY. With a 15.2% discount on dostarlimab, the ICER decreased to $150,000 per QALY in the pMMR EC. The univariate sensitivity analysis revealed that the cost of dostarlimab, utility of progression-free survival (PFS), and progressive disease (PD) had the most significant impacts on the outcomes. Probabilistic sensitivity analysis revealed that dostarlimab had a 100% likelihood of being considered cost-effective for patients at a WTP threshold of $150,000 per QALY for dMMR EC, whereas this likelihood was only 0.5% for pMMR EC.
    UNASSIGNED: Dostarlimab in combination with chemotherapy was cost-effective for primary advanced or recurrent dMMR EC from the perspective of a United States payer at a WTP threshold of $150,000 per QALY, but not for pMMR EC. Lowering the prices of dostarlimab could potentially enhance the cost-effectiveness of treatment for pMMR EC.

    背景:我们最初报告了一项为期6个月的随机对照实施试验的成本效益,该试验评估了HealthTAPESTRY,针对老年人的初级保健计划,在安大略省的麦克马斯特家庭健康团队(FHT)站点和其他5个FHT站点,加拿大。虽然在随机化后第6个月,两组间的结果差异无统计学意义,在麦克马斯特FHT站点观察到积极的结果,招募了40%(204/512)的参与者。这项事后研究的目的是根据McMasterFHT网站的数据确定HealthTAPESTRY的成本效益。
    方法:成本包括在McMaster实施HealthTAPESTRY的成本以及消耗的医疗保健资源,这是使用公开可用的来源计算成本的。在基线和随机化后第6个月用EQ-5L评估与健康相关的生活质量。质量调整寿命年(QALYs)是在曲线下面积法计算的。未调整和调整后的回归分析(对成本和QALY的两个独立回归分析,看似无关的回归[SUR],净收益回归)以及差异和倾向得分匹配(PSM)方法,用于处理试验的非随机性质。使用非参数自举估计试验数据固有的采样不确定性。计算了与HealthTAPESTRY相关的投资回报率(ROI)。所有费用均以2021加拿大元报告。
    结果:干预费用为293美元/患者,在未经调整和调整的分析中,健康TAPESTRY是首选策略。我们的引导分析结果表明,在普遍接受的WTP阈值下,与常规护理相比,HealthTAPESTRY具有成本效益。例如,如果决策者愿意为每获得的QALY支付5万美元,当WTP为$50,000/QALY时,与常规治疗相比,HealthTAPESTRY具有成本效益的概率从0.72(未调整分析)到0.96(SUR)不等.DID和ROI分析表明,HealthTapestry产生了积极的ROI。
    结论:在McMasterFHT实施时,健康TAPESTRY是首选策略。由于分析的事后性质和基于一个站点的有限样本量,我们在解释结果时谨慎小心。
    BACKGROUND: We initially reported on the cost-effectiveness of a 6-month randomized controlled implementation trial which evaluated Health TAPESTRY, a primary care program for older adults, at the McMaster Family Health Team (FHT) site and 5 other FHT sites in Ontario, Canada. While there were no statistically significant between-group differences in outcomes at month 6 post randomization, positive outcomes were observed at the McMaster FHT site, which recruited 40% (204/512) of the participants. The objective of this post-hoc study was to determine the cost-effectiveness of Health TAPESTRY based on data from the McMaster FHT site.
    METHODS: Costs included the cost to implement Health TAPESTRY at McMaster as well as healthcare resource consumed, which were costed using publicly available sources. Health-related-quality-of-life was evaluated with the EQ-5L-5L at baseline and at month 6 post randomization. Quality-adjusted-life-years (QALYs) were calculated under an-area-under the curve approach. Unadjusted and adjusted regression analyses (two independent regression analyses on costs and QALYs, seemingly unrelated regression [SUR], net benefit regression) as well as difference-in-difference and propensity score matching (PSM) methods, were used to deal with the non-randomized nature of the trial. Sampling uncertainty inherent to the trial data was estimated using non-parametric bootstrapping. The return on investment (ROI) associated with Health TAPESTRY was calculated. All costs were reported in 2021 Canadian dollars.
    RESULTS: With an intervention cost of $293/patient, Health TAPESTRY was the preferred strategy in the unadjusted and adjusted analyses. The results of our bootstrap analyses indicated that Health TAPESTRY was cost-effective compared to usual care at commonly accepted WTP thresholds. For example, if decision makers were willing to pay $50,000 per QALY gained, the probability of Health TAPESTRY to be cost effective compared to usual care varied from 0.72 (unadjusted analysis) to 0.96 (SUR) when using a WTP of $50,000/QALY gained. The DID and ROI analyses indicated that Health Tapestry generated a positive ROI.
    CONCLUSIONS: Health TAPESTRY was the preferred strategy when implemented at the McMaster FHT. We caution care in interpreting the results because of the post-hoc nature of the analyses and limited sample size based on one site.

    目标:由于与地面急救医疗服务(EMS)相比,直升机急救医疗服务(HEMS)在单价方面是一种昂贵的资源,重要的是进一步研究哪些方法可以优化这些服务。这项研究的目的是评估医生配备HEMS与地面EMS相比在开发场景中的成本效益,并改进分诊,航空性能,并纳入缺血性卒中患者。
    方法:通过比较HEMS与地面EMS在六种不同情况下的健康结果和成本来评估增量成本效益比(ICER)。使用估计的30天死亡率和质量调整生命年(QALYs)来衡量健康益处。使用EuroQoL仪器评估生活质量(QoL),并对不同患者组进行了单向敏感性分析.生存估计来自国家FinnHEMS数据库,根据最近的财务报告进行成本分析。
    结果:在方案3.1中取得了最好的结果,包括减少了过度警报,航空性能提升,和缺血性卒中患者的评估。这种情况产生了1077.07-1436.09额外的QALY,ICER为33,703-44,937€/QALY。与目前的做法相比,这表示额外的QALY增加了27.72%,ICER减少了21.05%。
    结论:通过将卒中患者纳入派遣标准,HEMS的成本效益可以大大提高,由于总成本是固定的,成本效益是根据产能利用率确定的。
    OBJECTIVE: Since Helicopter Emergency Medical Services (HEMS) is an expensive resource in terms of unit price compared to ground-based Emergency Medical Service (EMS), it is important to further investigate which methods would allow for the optimization of these services. The aim of this study was to evaluate the cost-effectiveness of physician-staffed HEMS compared to ground-based EMS in developed scenarios with improvements in triage, aviation performance, and the inclusion of ischemic stroke patients.
    METHODS: Incremental cost-effectiveness ratio (ICER) was assessed by comparing health outcomes and costs of HEMS versus ground-based EMS across six different scenarios. Estimated 30-day mortality and quality-adjusted life years (QALYs) were used to measure health benefits. Quality-of-Life (QoL) was assessed with EuroQoL instrument, and a one-way sensitivity analysis was carried out across different patient groups. Survival estimates were evaluated from the national FinnHEMS database, with cost analysis based on the most recent financial reports.
    RESULTS: The best outcome was achieved in Scenario 3.1 which included a reduction in over-alerts, aviation performance enhancement, and assessment of ischemic stroke patients. This scenario yielded 1077.07-1436.09 additional QALYs with an ICER of 33,703-44,937 €/QALY. This represented a 27.72% increase in the additional QALYs and a 21.05% reduction in the ICER compared to the current practice.
    CONCLUSIONS: The cost-effectiveness of HEMS can be highly improved by adding stroke patients into the dispatch criteria, as the overall costs are fixed, and the cost-effectiveness is determined based on the utilization rate of capacity.

    背景:患有晚期危重病的患者通常会接受比自己选择更多的强化治疗,这导致了生命即将结束时的高昂医疗费用。这项研究的目的是确定由跨专业ICU团队提供的家庭支持干预是否可以降低高死亡风险或严重功能障碍的危重患者的住院费用和再入院率。
    结果:我们检查了急性护理医院的住院费用指标以及出院后利用率,康复和熟练的护理设施,以及合作伙伴试验的临终关怀服务,一个多中心,阶梯式楔形,跨专业ICU家庭支持干预的整群随机试验。我们使用计算机化会计系统确定患者的总可控和直接可变成本。我们在6个月的随访中通过结构化电话访谈确定出院后资源利用率(如上文所定义)。我们使用多变量回归模型来比较组间的结果。与常规护理相比,PARTNER干预导致总可控成本显著降低(几何平均值:26,529美元vs32,105美元;对数线性系数:-0.30;95%CI-0.49,-0.11)和直接可变成本(3912美元vs6034美元;-0.33;95%CI-0.56,0.10)。死者的成本降低幅度更大(20,304美元与$26,610;-0.66;95%CI-1.01,-0.31)与幸存者($31,353与$35,015;-0.15;95%CI-0.35,0.05)。干预组中较低比例的患者再次入住急性护理医院(34.9%vs45.1%;0.66;95%CI0.56,0.77)或熟练护理机构(25.3%vs31.6%;0.63;95%CI0.47,0.84)。
    结论:跨专业ICU团队提供的家庭支持干预在6个月的随访中显著降低了指数住院费用和再入院率。试用登记号:NCT01844492。
    BACKGROUND: Patients with advanced critical illness often receive more intensive treatment than they would choose for themselves, which contributes to high health care costs near the end of life. The purpose of this study was to determine whether a family support intervention delivered by the interprofessional ICU team decreases hospitalization costs and hospital readmissions among critically ill patients at high risk of death or severe functional impairment.
    RESULTS: We examined index hospitalization costs as well as post-discharge utilization of acute care hospitals, rehabilitation and skilled nursing facilities, and hospice services for the PARTNER trial, a multicenter, stepped-wedge, cluster randomized trial of an interprofessional ICU family support intervention. We determined patients\' total controllable and direct variable costs using a computerized accounting system. We determined post-discharge resource utilization (as defined above) by structured telephone interview at 6-month follow-up. We used multiple variable regression modelling to compare outcomes between groups. Compared to usual care, the PARTNER intervention resulted in significantly lower total controllable costs (geometric mean: $26,529 vs $32,105; log-linear coefficient: - 0.30; 95% CI - 0.49, - 0.11) and direct variable costs ($3912 vs $6034; - 0.33; 95% CI - 0.56, - 0.10). A larger cost reduction occurred for decedents ($20,304 vs. $26,610; - 0.66; 95% CI - 1.01, - 0.31) compared to survivors ($31,353 vs. $35,015; - 0.15; 95% CI - 0.35,0.05). A lower proportion in the intervention arm were re-admitted to an acute care hospital (34.9% vs 45.1%; 0.66; 95% CI 0.56, 0.77) or skilled nursing facility (25.3% vs 31.6%; 0.63; 95% CI 0.47, 0.84).
    CONCLUSIONS: A family support intervention delivered by the interprofessional ICU team significantly decreased index hospitalization costs and readmission rates over 6-month follow-up. Trial registration Trial registration number: NCT01844492.

    背景:结肠直肠吻合口漏会对患者和医疗保健系统造成严重后果,因为它会导致医院资源和成本的消耗增加。吻合装置的技术改进可以减少泄漏的发生率及其经济影响。本研究的目的是评估使用新型动力圆形订书机是否具有成本效益。
    方法:这项观察性研究包括2018年1月至2021年12月接受左侧环形吻合术的患者。根据吻合是使用手动还是动力循环装置进行,进行倾向评分匹配以创建两个可比较的组。吻合口漏的发生率,其严重性,医院资源的消耗,其成本是主要的结果衡量标准。进行了比较动力圆形订书机与手动圆形订书机的成本效益分析。
    结果:共有330名患者被纳入研究,每组165。吻合口漏率显着不同(p=0.012):手动组22例(13.3%)与动力组8例(4.8%)。动力订书机和手动订书机的有效率分别为98.27%和93.69%,分别。动力组每位患者的平均费用为6238.38欧元,而手动组为9700.12欧元。增加的成本效益比为-每例无吻合口并发症的患者为-74,915.28欧元。
    结论:与手动设备相比,电动圆形吻合器的成本增加被吻合口瘘发生率降低和管理成本所节省的成本所抵消。
    BACKGROUND: Colorectal anastomotic leakage causes severe consequences for patients and healthcare system as it will lead to increased consumption of hospital resources and costs. Technological improvements in anastomotic devices could reduce the incidence of leakage and its economic impact. The aim of the present study was to assess if the use of a new powered circular stapler is cost-effective.
    METHODS: This observational study included patients undergoing left-sided circular stapled colorectal anastomosis between January 2018 and December 2021. Propensity score matching was carried out to create two comparable groups depending on whether the anastomosis was performed using a manual or powered circular device. The rate of anastomotic leakage, its severity, the consumption of hospital resources, and its cost were the main outcome measures. A cost-effectiveness analysis comparing the powered circular stapler versus manual circular staplers was performed.
    RESULTS: A total of 330 patients were included in the study, 165 in each group. Anastomotic leakage rates were significantly different (p = 0.012): 22 patients (13.3%) in the manual group versus 8 patients (4.8%) in the powered group. The effectiveness of the powered stapler and manual stapler was 98.27% and 93.69%, respectively. The average cost per patient in the powered group was €6238.38, compared with €9700.12 in the manual group. The incremental cost-effectiveness ratio was - €74,915.28 per patient without anastomotic complications.
    CONCLUSIONS: The incremental cost of powered circular stapler compared with manual devices was offset by the savings from lowered incidence and cost of management of anastomotic leaks.

    从中国和美国的社会角度评估索托拉西布与多西他赛在非小细胞肺癌(NSCLC)KRASG12C突变患者中的成本-效果。
    马尔可夫模型,包括三个状态(无进展生存期,进展后生存,和死亡)被开发。增量成本效益比(ICER),质量调整寿命年(QALY),并计算了两种治疗策略的增量QALY。单因素敏感性分析用于考察对模型结果影响较大的因素,和龙卷风图被用来展示结果。使用1,000个蒙特卡罗模拟进行了概率敏感性分析。假设分布基于参数类型,并且每次随机采样所有参数分布。,结果呈现为成本效益可接受曲线。
    这是对CodeBreak200随机临床试验数据的经济评估。在中国,sotorasib产生了0.44QAYL,总成本为84372.59美元。与多西他赛相比,索托拉斯的ICER值为102701.84美元/QALY,高于支付意愿(WTP),所以索托拉西没有经济优势。在美国,索托拉西比多西他赛获得0.35QALY,ICER为$15,976.50/QALY,大于1WTP但小于3WTP,表明索托拉西布的成本增加是可以接受的。单因素敏感性分析显示,随着我国后续检查费用的降低,索托拉西具有经济效益的概率逐渐增加。在中国的变化范围内,对结论没有影响。当支付意愿(WTP)超过102,500美元时,索托拉斯具有成本效应的概率从0%增加到49%。
    从美国的角度来看,Sotorasib具有成本效应。然而,从中国的角度来看,索托拉西没有成本效应,只有当WTP超过$102,500时,sotorasib具有成本效应的概率从0%增加到49%。
    UNASSIGNED: To evaluate the cost-effectiveness of sotorasib versus docetaxel in non-small cell lung cancer (NSCLC) patients with KRASG12C mutation from the China and United States\'social perspective.
    UNASSIGNED: A Markov model that included three states (progression-free survival, post-progression survival, and death) was developed. Incremental cost-effectiveness ratio (ICER), quality-adjusted life-year (QALY), and incremental QALY were calculated for the two treatment strategies. One-way sensitivity analysis was used to investigate the factors that had a greater impact on the model results, and tornado diagrams were used to present the results. Probabilistic sensitivity analysis was performed with 1,000 Monte Carlo simulations. Assume distributions based on parameter types and randomly sample all parameter distributions each time., The results were presented as cost-effectiveness acceptable curves.
    UNASSIGNED: This economic evaluation of data from the CodeBreak 200 randomized clinical trial. In China, sotorasib generated 0.44 QAYL with a total cost of $84372.59. Compared with docetaxel, the ICER value of sotorasib was $102701.84/QALY, which was higher than willingness to pay (WTP), so sotorasib had no economic advantage. In the US, sotorasib obtained 0.35 QALY more than docetaxel, ICER was $15,976.50/QALY, which was more than 1 WTP but less than 3 WTP, indicating that the increased cost of sotorasib was acceptable. One-way sensitivity analysis showed that the probability of sotorasib having economic benefits gradually increased when the cost of follow-up examination was reduced in China. And there was no influence on the conclusions within the range of changes in China. When the willingness to pay (WTP) exceeds $102,500, the probability of sotorasib having cost effect increases from 0% to 49%.
    UNASSIGNED: Sotorasib had a cost effect from the perspective in the United States. However, sotorasib had no cost effect from the perspective in China, and only when the WTP exceeds $102,500, the probability of sotorasib having cost effect increases from 0% to 49%.

    全固态锂离子电池(ASSLB)的商业化需要具有强大成本竞争力的固体电解质,低密度(用于实现令人满意的能量密度),和良好的阳极相容性(阴极相容性的需要可以避免的阴极涂层技术,广泛应用于基于硫化物的ASSLB)。然而,没有报道的氧化物,硫化物,或氯化物固体电解质同时满足这些要求。这里,我们设计了一种Li7P3S7.5O3.5(LPSO)固体电解质,这显示了所有上述特征的组合。这种材料的合成不需要昂贵的Li2S,所以原材料成本只有14.42美元/公斤,which,与大多数固体电解质不同,低于50美元/公斤的商业化门槛。LPSO的密度为1.70gcm-3,远低于氧化物(通常高于5gcm-3)和氯化物(约2.5gcm-3)固体电解质的密度。此外,LPSO还显示出优异的阳极相容性。Li|LPSO|Li电池在25°C下以0.1mAcm-2下〜50mV的电势稳定循环超过4200h,并且具有Si阳极的全固态软包电池在60°C下在88.6mAg-1下进行200次循环后显示出89.29%的容量保持率。
    The commercialization of all-solid-state Li batteries (ASSLBs) demands solid electrolytes with strong cost-competitiveness, low density (for enabling satisfactory energy densities), and decent anode compatibility (the need for cathode compatibility can be circumvented by the cathode coating techniques that are widely applied in sulfide-based ASSLBs). However, none of the reported oxide, sulfide, or chloride solid electrolytes meets these requirements simultaneously. Here, we design a Li7P3S7.5O3.5 (LPSO) solid electrolyte, which shows a combination of all the aforementioned characteristics. The synthesis of this material does not need the expensive Li2S, so the raw materials cost is only $14.42/kg, which, unlike most solid electrolytes, lies below the $50/kg threshold for commercialization. The density of LPSO is 1.70 g cm-3, considerably lower than those of the oxide (typically above 5 g cm-3) and chloride (around 2.5 g cm-3) solid electrolytes. Besides, LPSO also shows excellent anode compatibility. The Li | LPSO | Li cell cycles stably with a potential of ~50 mV under 0.1 mA cm-2 for over 4200 h at 25 °C, and the all-solid-state pouch cell with the Si anode shows a capacity retention of 89.29% after 200 cycles under 88.6 mA g-1 at 60 °C.

    目的:这项研究评估了口服营养补充剂(ONS)在中国的治疗益处并建立了成本效益模型。
    方法:数据收集自2018年1月1日至2020年12月31日的27152名成人住院患者。使用倾向评分匹配来平衡ONS组和非ONS组之间的基线特征。我们开发了一个决策树模型来评估ONS对有营养风险的患者的成本效益,增量成本效益比是确定最具成本效益战略的指标。进行了单向灵敏度和概率灵敏度分析以评估模型的稳定性。此外,根据临床特点进行亚组分析.使用Studentt检验比较两组间临床结果的差异,Mann-WhitneyU测试,或卡方检验。
    结果:ONS组显示前白蛋白水平明显降低,白蛋白,血红蛋白,入院时BMI高于非ONS组。恶性肿瘤的发病率,肠梗阻,ONS组的炎症性肠病明显高于非ONS组。ONS组的有效率明显高于非ONS组(51.7%对50.3%,P<0.05)。对决策树模型的分析表明,ONS组的成本增加了19850.96元,但获得了额外的1.3406有效率,导致增量成本效益比为14807.51,低于中国2020年人均国内生产总值71965元。敏感度剖析进一步证实了模子的鲁棒性。
    结论:ONS被证明具有很高的疗效,尽管目前使用ONS的患者通常处于严重疾病状态。此外,ONS具有成本效益。我们建议将ONS的报销范围扩大到包括营养风险高的住院患者。
    OBJECTIVE: This study assessed the therapeutic benefits and modeled the cost-effectiveness of oral nutritional supplements (ONS) in China.
    METHODS: Data were collected from 27 152 adult inpatients between January 1, 2018, and December 31, 2020. Propensity score matching was used for balancing the baseline characteristics between the ONS group and non-ONS group. A decision-tree model was developed to assess the cost-effectiveness of ONS for patients with nutritional risk, and the incremental cost-effectiveness ratio was the metric to determine the most cost-effective strategy. One-way sensitivity and probabilistic sensitivity analyses were conducted to assess the model\'s stability. In addition, subgroup analysis was conducted based on clinical characteristics. Differences in clinical outcomes between the groups were compared using Student\'s t test, Mann-Whitney U test, or chi-square test.
    RESULTS: The ONS group displayed significantly lower levels of prealbumin, albumin, hemoglobin, and BMI than the non-ONS group at admission. The incidence of malignant tumors, intestinal obstruction, and inflammatory bowel disease was significantly higher in the ONS group than the non-ONS group. The ONS group had a significantly higher effective rate than the non-ONS group (51.7% versus 50.3%, P < 0.05). Analysis of the decision-tree model revealed that the ONS group experienced an increase in cost of 19 850.96 yuan but achieved an additional 1.3406 effectiveness rate, resulting in an incremental cost-effectiveness ratio of 14 807.51, which fell below China\'s 2020 per capita gross domestic product of 71 965 yuan. Sensitivity analysis further confirmed the robustness of the model.
    CONCLUSIONS: ONS are demonstrated a high rate of efficacy, although patients currently using ONS are typically in a severe disease state. In addition, ONS is cost-effective. We suggest that the reimbursement coverage of ONS be expanded to include in-hospital patients who are at high nutritional risk.
