Rivaroxaban is the first oral factor Xa inhibitor approved in the US to reduce the risk of stroke and blood clots among people with non-valvular atrial fibrillation, treat deep vein thrombosis (DVT), treat pulmonary embolism (PE), reduce the risk of recurrence of DVT and PE, and prevent DVT and PE after knee or hip replacement surgery. The objective of this study was to evaluate the costs from a hospital perspective of treating patients with rivaroxaban vs other anticoagulant agents across these five populations.
Methods:
An economic model was developed using treatment regimens from the ROCKET-AF, EINSTEIN-DVT and PE, and RECORD1-3 randomized clinical trials. The distribution of hospital admissions used in the model across the different populations was derived from the 2010 Healthcare Cost and Utilization Project database. The model compared total costs of anticoagulant treatment, monitoring, inpatient stay, and administration for patients receiving rivaroxaban vs other anticoagulant agents. The length of inpatient stay (LOS) was determined from the literature.
Results:
Across all populations, rivaroxaban was associated with an overall mean cost savings of $1520 per patient. The largest cost savings associated with rivaroxaban was observed in patients with DVT or PE ($6205 and $2742 per patient, respectively). The main driver of the cost savings resulted from the reduction in LOS associated with rivaroxaban, contributing to ～90% of the total savings. Furthermore, the overall mean anticoagulant treatment cost was lower for rivaroxaban vs the reference groups.
Limitations:
The distribution of patients across indications used in the model may not be generalizable to all hospitals, where practice patterns may vary, and average LOS cost may not reflect the actual reimbursements that hospitals received.
Conclusion:
From a hospital perspective, the use of rivaroxaban may be associated with cost savings when compared to other anticoagulant treatments due to lower drug cost and shorter LOS associated with rivaroxaban. 相似文献
Methods: This BIM incorporated epidemiologic data, market uptake assumptions, and drug utilization costs, simulating the treatment mix for patients who are candidates for biologics before (Scenario #1) and after (Scenario #2) the introduction of C/BD foam. Predicted outcomes were expressed in terms of the annual cost of treatment (COT) and the COT per member per month (PMPM).
Results: At year 1, C/BD foam had the lowest per-patient cost ($9,913) necessary to achieve a Psoriasis Area and Severity Index (PASI)-75 response compared with etanercept ($73,773), adalimumab ($92,871), infliximab ($34,048), ustekinumab ($83,975), secukinumab ($113,858), apremilast ($47,960), and ixekizumab ($62,707). Following addition of C/BD foam to the formulary, the annual COT for moderate-to-severe psoriasis would decrease by $36,112,572 (17.91%, from $201,621,219 to $165,508,647). The COT PMPM is expected to decrease by $3.00 (17.86%, from $16.80 to $13.80).
Limitations: Drug costs were based on Medi-Span reference pricing (January 21, 2016); differences in treatment costs for drug administration, laboratory monitoring, or adverse events were not accounted for. Potentially confounding were the definition of “moderate-to-severe” and the heterogeneous efficacy data. The per-patient cost for PASI-75 response at year 1 was estimated from short-term efficacy data for C/BD foam and apremilast only.
Conclusions: The introduction of C/BD foam is expected to decrease the annual COT for moderate-to-severe psoriasis treatable with biologics by $36,112,572 for a hypothetical US healthcare plan with 1 million plan members, and to lower the COT PMPM by $3.00. 相似文献
To estimate biologic cost per effectively treated patient with rheumatoid arthritis (RA) using a claims-based algorithm for effectiveness.
Methods:
Patients with RA aged 18–63 years in the IMS PharMetrics Plus database were categorized as effectively treated if they met all six criteria: (1) a medication possession ratio ≥80% (subcutaneous) or at least as many infusions as specified in US labeling (intravenous); (2) no biologic dose increase; (3) no biologic switch; (4) no new non-biologic disease-modifying anti-rheumatic drug; (5) no new or increased oral glucocorticoid; and (6) ≤1 glucocorticoid injection. Biologic cost per effectively treated patient was defined as total cost of the index biologic (drug plus intravenous administration) divided by the number of patients categorized by the algorithm as effectively treated. Similar methods were used for the index biologic in the second year and for a second biologic after a switch.
Results:
Rates that the index biologic was categorized as effective in the first year were 31.0% etanercept (2243/7247), 28.6% adalimumab (1426/4991), 28.6% abatacept (332/1160), 27.2% golimumab (71/261), and 20.2% infliximab (474/2352). Mean biologic cost per effectively treated patient, per the algorithm, was $50,141 etanercept, $53,386 golimumab, $56,942 adalimumab, $73,516 abatacept, and $114,089 infliximab. Biologic cost per effectively treated patient, using this algorithm, was lower for patients who continued the index biologic in the second year and higher after switching.
Conclusions:
When a claims-based algorithm was applied to a large commercial claims database, etanercept was categorized as the most effective and had the lowest estimated 1-year biologic cost per effectively treated patient. This proxy for effectiveness from claims databases was validated against a clinical effectiveness scale, but analyses of the second year or the year after a biologic switch were not included in the validation. Costs of other medications were not included in cost calculations. 相似文献
A recent phase III trial showed that patients with advanced non-small cell lung cancer (NSCLC) whose tumors harbor specific EGFR mutations significantly benefit from first-line treatment with erlotinib compared to chemotherapy. This study sought to estimate the budget impact if coverage for EGFR testing and erlotinib as first-line therapy were provided in a hypothetical 500,000-member managed care plan.
Methods:
The budget impact model was developed from a US health plan perspective to evaluate administration of the EGFR test and treatment with erlotinib for EGFR-positive patients, compared to non-targeted treatment with chemotherapy. The eligible patient population was estimated from age-stratified SEER incidence data. Clinical data were derived from key randomized controlled trials. Costs related to drug, administration, and adverse events were included. Sensitivity analyses were conducted to assess uncertainty.
Results:
In a plan of 500,000 members, it was estimated there would be 91 newly diagnosed advanced NSCLC patients annually; 11 are expected to be EGFR-positive. Based on the testing and treatment assumptions, it was estimated that 3 patients in Scenario 1 and 6 patients in Scenario 2 receive erlotinib. Overall health plan expenditures would increase by $0.013 per member per month (PMPM). This increase is largely attributable to erlotinib drug costs, in part due to lengthened progression-free survival and treatment periods experienced in erlotinib-treated patients. EGFR testing contributes slightly, whereas adverse event costs mitigate the budget impact. The budget impact did not exceed $0.019 PMPM in sensitivity analyses.
Conclusions:
Coverage for targeted first-line erlotinib therapy in NSCLC likely results in a small budget impact for US health plans. The estimated impact may vary by plan, or if second-line or maintenance therapy, dose changes/interruptions, or impact on patients’ quality-of-life were included. 相似文献
The economic implications from the US Medicare perspective of adopting alternative treatment strategies for acute bacterial skin and skin structure infections (ABSSSIs) are substantial. The objective of this study is to describe a modeling framework that explores the impact of decisions related to both the location of care and switching to different antibiotics at discharge.
Methods:
A discrete event simulation (DES) was developed to model the treatment pathway of each patient through various locations (emergency department [ED], inpatient, and outpatient) and the treatments prescribed (empiric antibiotic, switching to a different antibiotic at discharge, or a second antibiotic). Costs are reported in 2012 USD.
Results:
The mean number of days on antibiotic in a cohort assigned to a full course of vancomycin was 11.2 days, with 64% of the treatment course being administered in the outpatient setting. Mean total costs per patient were $8671, with inpatient care accounting for 58% of the costs accrued. The majority of outpatient costs were associated with parenteral administration rather than drug acquisition or monitoring. Scenarios modifying the treatment pathway to increase the proportion of patients receiving the first dose in the ED, and then managing them in the outpatient setting or prescribing an oral antibiotic at discharge to avoid the cost associated with administering parenteral therapy, therefore have a major impact and lower the typical cost per patient by 11–20%. Since vancomycin is commonly used as empiric therapy in clinical practice, based on these analyses, a shift in treatment practice could result in substantial savings from the Medicare perspective.
Conclusions:
The choice of antibiotic and location of care influence the costs and resource use associated with the management of ABSSSIs. The DES framework presented here can provide insight into the potential economic implications of decisions that modify the treatment pathway. 相似文献
Methods: An insurance claims database with data on ～1.9 million company employees from January 2005 to May 2015 was used. Prevalence, demographics, and medical costs were analyzed by cross-sectional analysis, and incidence and treatment status were analyzed by longitudinal analysis among newly-diagnosed GERD patients.
Results: GERD prevalence in 2014 was 3.3% among 20–59 year-olds, accounting for 40,134 people in the database, and GERD incidence increased from 0.63% in 2009 to 0.98% in 2014. In 2014, mean medical cost per patient per month for GERD patients aged 20–59 was JPY 31,900 (USD 266 as of January 2016), which was ～2.4-times the mean national healthcare cost. The most frequently prescribed drugs for newly-diagnosed GERD patients were proton pump inhibitors (PPIs). Although PPIs were prescribed more often in patients with more doctor visit months, over 20% of patients that made frequent doctor visits (19 or more visits during a 24 calendar months period) were prescribed PPIs during only 1 calendar month or not at all.
Limitations: The database included only reimbursable claims data and, therefore, did not cover over-the-counter drugs. The database also consisted of employee-based claims data, so included little data on people aged 60 years and older.
Conclusions: Given the increasing incidence of GERD in Japan there is a need for up-to-date information on GERD incidence. This study suggests that some GERD patients may not be receiving appropriate treatment according to Japanese guidelines, which is needed to improve symptom control. 相似文献
This retrospective cohort analysis was conducted to examine the cost components of administering IV chemotherapy to peripheral T-cell lymphoma (PTCL) patients in the US to inform decision makers.
Methods:
Patients diagnosed with PTCL (ICD-9 code 202.7X) between 1 October 2007 and 30 September 2012 were identified from a US administrative claims database. Costs for patients receiving at least one NCCN recommended IV chemotherapy were assessed using the allowed payment from claim line items, categorized into cost components (study drug costs, IV administration costs and other visit-related services).
Results:
The mean costs to the payer for IV cancer therapy administration in a PTCL patient population averaged about $5735 per visit and $9356 per member per month (PMPM). Across all therapies, mean IV administration costs accounted for $127–$794 per visit and $594–$1808 PMPM, contributing an additional 2–32% to the total costs of the drug alone. Mean other visit-related services costs for treating PTCL accounted for $70–$2487 per visit and $444–$3094 PMPM, contributing an additional 2–74% to the total costs. Combined, these additional costs represent an additional mean cost of $220–$3150 per visit and $1193–$4609 PMPM to the base price of the drug alone.
Limitations:
This study used a convenience sample to identify PTCL patients and only included visits where at least one NCCN recommended IV chemotherapy was administered.
Conclusions:
The costs of IV administration and other visit-related services add measurable costs to the total cost of IV therapy for treating PTCL. When considering the cost of the drug, these additional costs can represent a substantial proportion of the overall costs and must be considered when evaluating the costs of IV treatment options for PTCL. 相似文献
The goal of this study is to determine the cost-effectiveness of MIRISK VP, a next generation coronary heart disease risk assessment score, in correctly reclassifying and appropriately treating asymptomatic, intermediate risk patients.
Study design:
A Markov model was employed with simulated subjects based on the Multi-Ethnic Study of Atherosclerosis (MESA). This study evaluated three treatment strategies: (i) practice at MESA enrollment, (ii) current guidelines, and (iii) MIRISK VP in MESA.
Methods:
The model assessed patient healthcare costs and outcomes, expressed in terms of life years and quality-adjusted life years (QALYs), over the lifetime of the cohort from the provider and payer perspective. A total of 50,000 hypothetical individuals were used in the model. A sensitivity analysis was conducted (based on the various input parameters) for the entire cohort and also for individuals aged 65 and older.
Results:
Guiding treatment with MIRISK VP leads to the highest net monetary benefits when compared to the ‘Practice at MESA Enrollment’ or to the ‘Current Guidelines’ strategies. MIRISK VP resulted in a lower mortality rate from any CHD event and a modest increase in QALY of 0.12–0.17 years compared to the other two approaches.
Limitations:
This study has limitations of not comparing performance against strategies other than the FRS, the results are simulated as with all models, the model does not incorporate indirect healthcare costs, and the impact of patient or physician behaviors on outcomes were not taken into account.
Conclusions:
MIRISK VP has the potential to improve patient outcomes compared to the alternative strategies. It is marginally more costly than both the ‘Practice at MESA Enrollment’ and the ‘Current Guidelines’ strategies, but it provides increased effectiveness, which leads to positive net monetary benefits over either strategy. 相似文献
Myelofibrosis is a non-frequent chronic myeloproliferative Philadelphia-negative chromosome neoplasm. It is a heavy incapacitating orphan disease and associated with high morbidity and mortality. In this context, indirect and non-medical costs are expected to be high. The main objective of this project is to estimate the economic burden of this disease in Spain.
Methods:
Thirty-three patients with a diagnosis of myelofibrosis for at least 1 year participated in a questionnaire in three Spanish centers. The study consisted of analyzing in various aspects the cost and impact of the disease; indeed, daily life time limitations with a need of informal care, symtomatology. Additionally, information concerning the clinical management of the disease was collected through a focus group of eight experts.
Results:
The mean age was 65 years. 15 of 33 patients were at their productive stage. Six had difficulties at work and eight have received informal care. Bone and muscular pain were the main symptoms of patients (72%). The estimated global indirect and non-medical costs of the disease were 86,315€ per patient (20% working and 80% informal care), which reached 104,153€ at productive stage patients (45%) and 168,459€ for more symptomatic patients.
Conclusions:
The economic burden of indirect and non-medical costs of myelofibrosis are important (15,142€/annual) as a result, and should be considered in economic evaluation, as well as in preventive plans for patients and caregivers, despite the fact that studies with larger numbers of patients should be done. 相似文献
Patients with persistent or longstanding atrial fibrillation have modest success achieving sinus rhythm with catheter ablation or rhythm control medications. Their high risk of stroke, bleed, and heart failure leads to significant morbidity and health care costs. The convergent procedure has been shown to be successful in this population, with 80% of patients in sinus rhythm after 1 year. This study evaluated the cost-effectiveness of the convergent procedure, catheter ablation, and medical management for non-paroxysmal AF patients.
Methods:
A Markov micro-simulation model was used to estimate costs and effectiveness from a payer perspective. Parameter estimates were from the literature. Three patient cohorts were simulated, representing lower, medium, and higher risks of stroke, bleed, heart failure, and hospitalization. Effects were estimated by quality-adjusted life-years (QALYs). Single-variable sensitivity analysis was performed.
Results:
After 5 years, convergent procedure patients averaged 1.10 procedures, with 75% of survivors in sinus rhythm; catheter ablation patients had 1.65 procedures, with 49% in sinus rhythm. Compared to medical management, catheter ablation and the convergent procedure were cost-effective for the lower risk (ICER <$35,000) and medium risk (ICER <$15,000) cohorts. The procedures dominated medical management for the higher risk cohort (lower cost and higher QALYs). The convergent procedure dominated catheter ablation for all risk cohorts. Results were subject to simplifying assumptions and limited by uncertain factors such as long-term maintenance of sinus rhythm after successful procedure and incremental AF-associated event rates for AF patients relative to patients in sinus rhythm. In the absence of clinical trial data, convergent procedure efficacy was estimated with observational evidence. Limitations were addressed with sensitivity analyses and a moderate 5 year time horizon.
Conclusion:
The convergent procedure results in superior maintenance of post-ablation sinus rhythm with fewer repeat ablation procedures compared to catheter ablation, leading to lower cost and higher QALYs after 5 years. 相似文献
The aim of this study was to evaluate medication adherence and persistence of patients treated with Etanercept and Adalimumab for Rheumatoid Arthritis, also giving economic evaluations on therapy costs for Received Daily Dose (RDD).
Materials and methods:
This retrospective study took into account 6 years from January 1, 2007 to December 31, 2012. Medication adherence was quantified utilizing the ratio between RDD and Prescribed Daily Dose (PDD). Persistence has been reckoned taking into account the actual days of therapy comparing posology with supplied dose. The persistence has been graphed according to Kaplan-Meier method. The cost per RDD was reckoned starting from the expense incurred by Pescara General Hospital.
Results:
Medication adherence gave results in values between 0.88–0.97 for Etanercept and 0.83–0.90 for Adalimumab. The value of persistence was 100% for Etanercept and 90% for Adalimumab for the first year, and 70% for Etanercept and 80% for Adalimumab for the second year. In the 3rd year the persistence for Etanercept was 50% while for Adalimumab it was 60%. In the fourth year the persistence for Etanercept was 21% while for Adalimumab it was 27%. The statistical analysis was conducted using the Log rank test. The average cost per RDD was €32.97 for Etanercept and for Adalimumab it was €32.00 as an average of 6 years.
Conclusion:
The medication adherence was good for both Etanercept and Adalimumab. The rate of persistence decreased strictly in the fourth year of treatment. This data suggests the need for continuous monitoring of patients in treatment with TNF blockers. 相似文献
Telaprevir (T, TVR) is a direct-acting antiviral (DAA) used for the treatment of genotype 1 chronic hepatitis C virus (HCV) infection. The sustained virological response (SVR) rates, i.e., undetectable HCV RNA levels 24 weeks after the end of treatment, is what differentiate treatments. This analysis evaluated the cost-effectiveness of TVR combined with pegylated interferon (Peg-IFN) alfa-2a plus ribavirin (RBV), with Peg-IFN and RBV (PR) alone or with boceprevir (B, BOC) plus Peg-IFN alfa-2b and RBV, in naïve patients.
Methods:
A Markov cohort model of chronic HCV disease progression reflected the pathway of naïve patients initiating anti-HCV therapy. SVR rates were derived from a mixed-treatment comparison including results from Phase II and III trials of TVR and BOC, and trials comparing both PR regimens. SVR has significant impact on survival, quality-of-life, and costs. Incremental cost per life year (LY) gained and quality-adjusted-life-year (QALY) gained were computed at lifetime, adopting the (National Health Service) NHS perspective. Cost and health outcomes were discounted at 3.5%. Uncertainty was assessed using deterministic and probabilistic sensitivity analyses. Sub-group analyses were also performed by interleukin (IL)-28B genotype and fibrosis stage.
Results:
Higher costs and improved outcomes were associated with T/PR relative to PR alone, resulting in an ICER of £12,733 per QALY gained. T/PR retained a significant SVR advantage over PR alone and was cost-effective regardless of IL-28B genotype and fibrosis stages. T/PR regimen ‘dominated’ B/PR, generating 0.2 additional QALYs and reducing lifetime cost by £2758. Sensitivity analyses consistently resulted in ICERs less than £30,000/QALY for the T/PR regimen over PR alone.
Limitations:
No head-to-head trial provides direct evidence of better efficacy of T/PR vs B/PR.
Conclusion:
The introduction of TVR-based therapy for genotype 1 HCV patients is cost-effective for naïve patients at the £30,000 willingness-to-pay threshold, regardless of IL-28B genotype or fibrosis stage. 相似文献
To determine the cost-effectiveness of home-based point-of-care self-monitoring compared to clinic-based care for patients managed on long-term warfarin medication. Current evidence is inconsistent; results should reduce uncertainty and inform service delivery.
Methods:
A Markov model compared self-testing and self-management, using point-of-care devices to usual care in patients with atrial fibrillation and mechanical heart valves. The primary clinical end-points were stroke and mortality avoided; costs and utilities were associated with these events. The costs of warfarin monitoring were included in the model.
Results:
Over 10 years, self-monitoring saved £1187 per person compared to usual care. Patients who self-monitored had notably fewer strokes and deaths. The results were sensitive to life-years gained and cost of the device. If the NHS purchased the device, financial break-even was achieved at the end of the second year; if the patient bought the device the NHS saved money every year. If 10% of the current 950,000 patients switched to point-of-care devices for 10 years, the NHS could save over £112million.
Limitations:
Clinical studies had a relatively short duration and only data on composite end-points were reported.
Conclusions:
With training, self-testing and self-management are safe, reliable, and cost-effective for a sizable proportion of patients receiving long-term warfarin. Compared to clinic-based services, self-monitoring offers the NHS the potential to make cost savings and release bed-days by reducing the number of strokes experienced by these high-risk patients. 相似文献
Knee cartilage damage is a common cause of referral for orthopedic surgery. Treatment aims to reduce pain and symptoms by repairing cartilage. Microfracture, the current standard of care, yields good short-term clinical outcomes; however, treatment might fail after 2–3 years. A Chitosan-Beta glycerolphosphate-based medical device (BST-CarGel) is used as an adjunct to microfracture and demonstrates improvements in quantity and quality of repaired tissue, potentially reducing the risk of treatment failure. This study aimed to establish the economic value of BST-CarGel vs microfracture alone in knee cartilage repair from the societal perspective, using Germany as the reference market.
Methods:
A decision tree with a 20-year time-horizon was constructed, in which undesirable clinical events were inferred following initial surgery. These events consisted of pain management, surgery, and total knee replacement. Clinical outcomes were taken from the pivotal clinical trial, supplemented by other literature. Data and assumptions were validated by a Delphi panel. All relevant resource use and costs for procedures and events were considered.
Results:
In a group of patients with all lesion sizes, the model inferred that BST-CarGel yields a positive return on investment at year 4 (with 20-year cumulative cost savings of €6448). Reducing the incremental risk of treatment failure gap between the device and microfracture by 25–50% does not alter this conclusion. Cost savings are greatest for patients with large lesions; results for patients with small lesions are more modest.
Limitations:
Clinical evidence for microfracture and other interventions varies in quality. Comparative long-term data are lacking. The comparison is limited to microfracture and looks only at costs without considering quality-of-life.
Conclusion:
BST-CarGel potentially represents a cost-saving alternative for patients with knee cartilage injury by reducing the risk of clinical events through regeneration of chondral tissue with hyaline characteristics. Since the burden of this condition is high, both to the patient and society, an effective and economically viable alternative is of importance. 相似文献
This study compares the cost-effectiveness of intravitreal ranibizumab vs observation and/or laser photocoagulation for treatment of macular edema secondary to retinal vein occlusion in a UK-based model.
Methods:
A Markov model was constructed using transition probabilities and frequency of adverse events derived using data from the BRAVO, CRUISE, and HORIZON trials. Outcomes associated with treatments and health states were combined to predict overall health costs and outcomes for cohorts treated with each option.
Results:
In branch retinal vein occlusion, ranibizumab produced a gain of 0.518 quality-adjusted life years at an incremental cost of £8141, compared with laser photocoagulation. The incremental cost-effectiveness ratio was £15,710 per quality-adjusted life year, and the incremental cost per month free from blindness was £658. In central retinal vein occlusion, ranibizumab produced a gain of 0.539 quality-adjusted life years at an incremental cost of £9216, compared with observation only. The incremental cost-effectiveness ratio was £17,103, and the incremental cost per month free from blindness was £423.
Conclusions:
These incremental cost-effectiveness ratios are below the £20,000–30,000 range typically accepted as a threshold for cost-effectiveness. This suggests that ranibizumab may be regarded as a cost-effective therapy for patients with macular edema secondary to retinal vein occlusion, relative to grid laser photocoagulation (for BRVO) and observation (for CRVO). Limitations include sparse data for utilities associated with the severity of visual impairment in the WSE in patients with RVO. A lack of direct comparative evidence between ranibizumab and the dexamethasone intravitreal implant for the treatment of BRVO and CRVO and the infeasibility of an indirect comparison due to significant heterogeneity in trial designs prevented the inclusion of this treatment as a comparator in the Markov model. 相似文献
To develop a decision-analytic model to estimate the cost-effectiveness of initiating maintenance treatment with aripiprazole once-monthly (AOM) vs paliperidone long-acting injectable (PLAI) once-monthly among patients with schizophrenia in the US.
Methods:
A decision-analytic model was developed to evaluate a hypothetical cohort of patients initiating maintenance treatment with AOM or PLAI. Rates of relapse, adverse events (AEs), and direct medical costs were estimated for 1 year. Patients either remained on initial treatment or discontinued treatment due to lack of efficacy, AEs, or other reasons, including non-adherence. Data from placebo-controlled pivotal trials and product prescribing information (PI) were used to estimate treatment efficacy and AEs. Analyses were performed assuming dosing of clinical trials, real-world practice, PIs, and highest therapeutic dose available, because of variation in practice settings. The main outcome of interest was incremental cost per schizophrenia hospitalization averted with AOM vs PLAI.
Results:
Based on placebo-controlled pivotal trials’ dosing, AOM improved clinical outcomes by reducing schizophrenia relapses vs PLAI (0.181 vs 0.277 per person per year [pppy]) at an additional cost of US$1276 pppy, resulting in an incremental cost-effectiveness ratio (ICER) of US$13,280/relapse averted. When PI dosing was assumed, this ICER increased to US$19,968/relapse averted. When real-world dosing and highest available dosing were assumed, AOM was associated with fewer relapses and lower overall treatment costs vs PLAI.
Conclusions:
AOM consistently provided favorable clinical benefits. Under various dosing scenarios, AOM results indicated fewer relapses at lower overall costs or a reasonable cost-effectiveness threshold (i.e., less than the cost of a hospitalization relapse) vs PLAI. Given the heterogeneous nature of schizophrenia and variability in treatment response, health plans may consider open access for treatments like AOM. Since model inputs were based on data from separate placebo-controlled trials, generalization of results to the real-world setting is limited. 相似文献
Celecoxib for the treatment of pain resulting from osteoarthritis (OA) was reviewed by the Tandvårds- och läkemedelsförmånsverket–Dental and Pharmaceutical Benefits Board (TLV) in Sweden in late 2010. This study aimed to evaluate the incremental cost-effectiveness ratio (ICER) of celecoxib plus a proton pump inhibitor (PPI) compared to diclofenac plus a PPI in a Swedish setting.
Methods:
The National Institute for Health and Care Excellence (NICE) in the UK developed a health economic model as part of their 2008 assessment of treatments for OA. In this analysis, the model was reconstructed and adapted to a Swedish perspective. Drug costs were updated using the TLV database. Adverse event costs were calculated using the regional price list of Southern Sweden and the standard treatment guidelines from the county council of Stockholm. Costs for treating cardiovascular (CV) events were taken from the Swedish DRG codes and the literature.
Results:
Over a patient’s lifetime treatment with celecoxib plus a PPI was associated with a quality-adjusted life year (QALY) gain of 0.006 per patient when compared to diclofenac plus a PPI. There was an increase in discounted costs of 529kr per patient, which resulted in an incremental cost-effectiveness ratio (ICER) of 82,313kr ($12,141). Sensitivity analysis showed that treatment was more cost effective in patients with an increased risk of bleeding or gastrointestinal (GI) complications.
Conclusions:
The results suggest that celecoxib plus a PPI is a cost effective treatment for OA when compared to diclofenac plus a PPI. Treatment is shown to be more cost effective in Sweden for patients with a high risk of bleeding or GI complications. It was in this population that the TLV gave a positive recommendation. There are known limitations on efficacy in the original NICE model. 相似文献
Traditional pathology techniques alone can be insufficient to reliably distinguish between malignant melanoma, dysplastic nevi, and benign nevi in biopsies of suspicious pigmented lesions. Numerous studies have shown high rates of ambiguity when assessing such samples. A novel gene expression assay has been developed to objectively differentiate malignant melanoma from benign nevi.
Objective:
The purpose of this study was to quantify the economic impact of the gene expression assay on a US commercial health plan.
Methods:
The clinical paradigm of care was modeled for a hypothetical cohort of patients with suspicious pigmented lesions that are difficult-to-diagnose. Costs were assigned to each unit of care provided based on 2013 Medicare fee-for-service rates. Patients were followed for 10 years and were modeled to progress according to the natural history of their disease. The total cost of care was calculated for two scenarios: a Reference Scenario, representing current clinical practice, and a Test Scenario, in which each lesion was tested with the gene expression assay and diagnosed. Total cost of care was compared between the two scenarios to determine overall budget impact. Sensitivity analyses were performed to test the robustness of the model.
Results:
The gene expression assay reduces costs by $1268 per patient tested over 10 years, a decrease of 8.3%, after accounting for the cost of the assay. For a health plan with 10 million members, this would translate to over $8 million in savings. The largest portion of this saving comes from reducing the number of missed melanomas, which would otherwise progress to advanced disease. In sensitivity analyses, no single model input changed within a reasonable range of values caused the model to show that the assay was not cost-saving.
Conclusion:
In addition to improving the diagnosis of melanoma, this gene expression assay would likely reduce costs for health plans that choose to cover it. 相似文献
Aim: To estimate the budget impact and cost-effectiveness of introducing defibrotide to a transplant center.
Methods: The authors developed a budget impact model from the perspective of a bone-marrow transplant center. It was estimated that 2.3% of adults and 4.2% of children would develop VOD with MOD following HSCT based on a retrospective hospital database analysis and the effect that treating patients with defibrotide would have on costs for adult and pediatric centers was estimated. A cost-utility analysis (CUA) was also developed to capture the long-term cost-effectiveness of defibrotide. Projected life expectancies in the two groups were estimated based on trial data, transplant registry data, studies of long-term survival among HSCT patients, and US population life-tables.
Results: There was an estimated 3% increase ($330,706) per year in total adult transplantation center costs associated with adopting defibrotide, and a <1% increase ($106,385) for pediatric transplant centers, assuming 100 transplants per year. In the CUA, the lifetime increase in cost per patient was $106,928, life expectancy increased by 3.74 years, and quality-adjusted life-years (QALYs) increased by 2.24. The incremental cost-effectiveness ratio (ICER) was $47,736 per QALY gained; 88% probability defibrotide was cost-effective at a $100,000/QALY threshold.
Conclusion: The budget impact of defibrotide for a transplant center is relatively modest compared to the overall cost of transplantation. Defibrotide provides an important survival advantage for VOD with MOD patients, and the life years gained lead to defibrotide being highly cost-effective. 相似文献
To evaluate the cost-effectiveness of bendamustine-rituximab (B-R) compared with CHOP-R (cyclophosphamide, doxorubicin, vincristine, prednisone, rituximab) and CVP-R (cyclophosphamide, vincristine, prednisone, rituximab) as first-line treatment for patients with advanced indolent non-Hodgkin’s lymphoma (NHL).
Methods:
A patient-level simulation was adapted from the model used by the University of Sheffield School of Health and Related Research (ScHARR) in a health technology appraisal of rituximab for first-line treatment of follicular lymphoma. This approach allowed modelling of the complex treatment pathways in indolent NHL. Data from a Phase 3 randomized, open-label trial were used to compare B-R with CHOP-R. The relative efficacy of CHOP-R and CVP-R was estimated using an indirect treatment comparison similar to the original ScHARR approach. The analysis was conducted from the perspective of the National Health Service in England and Wales, using a lifetime time horizon. A number of one-way sensitivity and scenario analyses were conducted, including one using recently published data comparing CVP-R with CHOP-R.
Results:
The deterministic incremental cost-effectiveness ratio (ICER) was £5249 per quality adjusted life year (QALY) for B-R vs CHOP-R, and £8092 per QALY for B-R vs CVP-R. The alternative scenario using direct data comparing CVP-R with CHOP-R approximately halved the ICER for B-R vs CVP-R to £4733. Owing to its better toxicity profile, B-R reduced the cost of treating adverse events by over £1000 per patient vs CHOP-R.
Limitations:
The main limitations were: immaturity of overall survival data from the Phase 3 trial; reliance on quality-of-life data from previous health technology appraisals (as this was not collected in the trial); and a lack of direct evidence or a network of connected evidence comparing B-R with CVP-R.
Conclusions:
The ICERs for B-R vs CHOP-R and CVP-R were considerably below the thresholds normally regarded as cost-effective in England and Wales (£20,000–30,000 per QALY). 相似文献
