Introduction: Prophylaxis is the recommended management strategy for all persons with hemophilia (PwH), yet its adoption is uneven worldwide., Areas Covered: This analysis examines global disparities in hemophilia care, focusing on global prophylactic coverage and its correlation with the World Bank's world development indicators. It outlines the disproportionate consumption of clotting factors and non-factor concentrates in high-income countries compared to lower-income counterparts and the challenges of expanding prophylaxis coverage in under-resourced settings. The analysis integrates socioeconomic data with global health indicators to understand these disparities and advocates for increased distribution of treatment resources across all income levels, emphasizing the need for policy changes to improve hemophilia care worldwide. Studies addressing the prophylaxis perspectives in hemophilia were selected using PubMed and Google Scholar platforms (unlimited time frame). Articles were supplemented with WFH's annual surveys and guidelines, including the WFH Global Survey 2022, WFH Guidelines for the Management of Hemophilia 2020 and World Bank data., Expert Opinion: Significant disparities in hemophilia care and factor usage exist between high-income and lower-income countries. Standardized, harmonized metrics for different types of factor consumption are critical to accurately assess and compare hemophilia care on an international basis.

Background: Patients on warfarin with traumatic intracranial hemorrhage often have the warfarin effects pharmacologically reversed. We compared outcomes among patients who received 4-factor prothrombin complex concentrate (PCC), fresh frozen plasma (FFP), or no reversal to assess the real-world impact of PCC on elderly patients with traumatic intracranial hemorrhage (ICH)., Materials and Methods: This was a retrospective analysis of 150 patients on preinjury warfarin. Data were manually abstracted from the electronic medical record of an academic level 1 trauma center for patients admitted between January 2013 and December 2018. Outcomes were ICH progression on follow-up computed tomography scan, mortality, need for surgical intervention, and trends in the use of reversal agents., Results: Of 150 patients eligible for analysis, 41 received FFP, 60 PCC, and 49 were not reversed. On multivariable analysis, patients not reversed [OR 0.25 95% CI (0.31-0.85)] and women [OR 0.38 95% CI (0.17-0.88)] were less likely to experience progression of their initial bleed on follow-up computed tomography while subdural hemorrhage increased the risk [OR 3.69 95% CI (1.27-10.73)]. There was no difference between groups in terms of mortality or need for surgery. Over time use of reversal with PCC increased while use of FFP and not reversing warfarin declined (P < 0.001)., Conclusions: Male gender and using a reversal agent were associated with progression of ICH. Choice of reversal did not impact the need for surgery, hospital length of stay, or mortality. Some ICH patients may not require warfarin reversal and may bias studies, especially retrospective studies of warfarin reversal., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Controversy exists regarding first-line use of the recently approved reversal agent andexanet alfa due to limitations of the ANEXXA-4 study, thrombotic risks, and high medication acquisition cost. The purpose of this study was to evaluate the safety and effectiveness of 4F-PCC for the reversal of emergent oral fXa inhibitor-related bleeding. Furthermore, we aimed to evaluate a subgroup using strict ANNEXA-4 patient selection criteria., Methods: This was a retrospective study conducted utilizing chart review of adult patients that received 4F-PCC for oral fXa inhibitor-related bleeding. The primary endpoint was the rate of clinical success defined as achieving excellent or good hemostatic effectiveness following the administration of 4F-PCC. Secondary endpoints included in-hospital mortality and arterial/venous thromboembolism, and cost compared with andexanet alfa., Results: A total of 119 patients were included, with 83 patients in the ANNEXA-4 criteria subgroup. Eighty-five of the 119 patients (71%) required reversal due to intracranial bleeding. Prior to reversal, 70 patients (59%) were taking apixaban and 49 patients (41%) were taking rivaroxaban. Clinical success was achieved in 106 of 119 patients (89%) and 74 of 83 patients (90%) in the strict criteria subgroup. Three of 119 patients (2.5%) had a thrombotic event during hospital stay and the overall mortality rate was 13%. The average cost increase of andexanet alfa compared to 4F-PCC would have been $29,500 per patient., Conclusions: Administration of 4F-PCC for the reversal of oral fXa inhibitors was effective with relatively low thrombotic risk. Further direct prospective comparison of 4F-PCC to andexanet alfa is warranted., Competing Interests: Declaration of Competing Interest All authors have declared they have no conflict of interest relevant to this work., (Copyright © 2020 Elsevier Inc.

Although therapeutic drivers are changing over the years, and innovative biotech products are continuously modifying the clinical landscape, there is an increasing need for plasma protein therapies obtained by the fractionation of human plasma. Plasma-derived protein products therefore continue to play vital roles in the therapeutic management of various immunological disorders, deficiencies in coagulation factors or protease inhibitors, viral or bacterial infections, and trauma. Plasma fractionation is a biotechnology industry that has increased in complexity over the last 30 years to ensure that plasma-derived protein therapies exhibit optimal quality and pathogen safety profiles. Plasma-derived products are among the safest biological therapies available; in industrialized countries they are strictly and efficiently regulated in all aspects of their production chain and clinical use. Conversely, due to some technological complexities and strict adherence to regulatory requirements, a substantial barrier to entry into the field of plasma fractionation exists. Although various plasma-derived protein products are on the WHO model list of essential medicines, dramatic shortages of these products exist, especially in low-/medium income countries, while at the same time more than 9 million liters of recovered plasma in these countries are wasted annually. Lack of plasma protein products results mainly from three factors: (a) cost of imported products, (b) insufficient local supply of quality plasma for fractionation, or (c) lack of domestic industrial fractionation capacity. As the understanding of critical quality and safety factors has dramatically improved over the years, there is a need to rethink how affordable, scalable, and reliable purification and virus inactivation technologies could be introduced in countries with poor relevant infrastructures and low-/medium income. Such technologies, when properly validated and implemented, could help ensure local availability of essential plasma protein therapies and gradually fill the gap in product supply, safety and affordability that exists relative to advanced economies., Competing Interests: Declaration of Competing Interest The authors declare non-competing interest.

Andexanet-alpha is a specific reversal agent for direct factor Xa inhibitors (dFXaI). We aimed to project utilization rates and cost of andexanet for reversal of dFXaI-related major hemorrhage compared to 4-factor prothrombin complex concentrates (4F-PCC). A retrospective, multicenter review was conducted between 1/1/2014 and 7/15/2018 of patients who received 4F-PCC for reversal of dFXaI-related life-threatening hemorrhages. Total hospital reimbursements/patient were calculated based on national average MS-DRG payments adjusting for Medicare discounts. The projected cost for andexanet (based on dose and insurance) and % reimbursement/patient was compared to the actual cost of 4F-PCC. Hemostasis at 24 h (excellent/good vs. poor) and 30-day thrombotic complications were assessed. Of 126 patients who received 4F-PCC to reverse dFXaI, 46 (~ 10 per-year) met inclusion criteria. The median projected cost of andexanet was $22,120/patient, compared to $5670/patient for 4F-PCC (P < 0.001). The median hospital reimbursement was $11,492/hospitalization. The projected cost of andexanet alone would exceed the entire hospital reimbursement in 74% of patients by a median of $7604, while 4F-PCC cost exceeded the total hospital payments in 7% of patients in the same cohort (P < 0.001). Hemostasis was excellent/good in 72% of patients post-4F-PCC, compared to 82% in andexanet trials. Thromboembolic events occurred in 4% of patients following 4F-PCC versus 10% in andexanet trials. The projected cost of andexanet would exceed the national average hospital reimbursement/patient in nearly 75% of patients by over $7500/hospitalization. 4F-PCC was significantly less expensive, had lower rates of thrombosis, but also lower rates of good/excellent hemostasis compared to published data for andexanet.

Background: Four-factor prothrombin complex concentrate (4F-PCC) is US Food and Drug Administration approved for the urgent reversal of coagulation factor deficiency induced by a vitamin K antagonist complicated by acute major bleeding or in situations in which invasive procedures are urgently needed. Although recent evidence suggests the superiority of 4F-PCC over plasma for on-label indications, the off-label use of 4F-PCC has not been rigorously studied., Study Design and Methods: Eighty-nine patients receiving 4F-PCC at a single institution from July 2016 to December 2017 were retrospectively analyzed. Two cohorts, "On-Label" and "Off-Label" uses of 4F-PCC, were evaluated, comparing patient characteristics, blood utilization, and clinical outcomes including in-hospital mortality., Results: Patients receiving 4F-PCC for off-label reasons (n = 46) were younger and sicker compared to those receiving 4F-PCC for on-label reasons (n = 43). Notably, the mortality rate for off-label use was approximately twofold greater than the mortality rate for on-label use (26 of 46 [56.5%] vs. 12 of 43 [27.9%]; p = 0.006). Patients receiving 4F-PCC for off-label reasons received more units per patient of each blood component than their on-label counterparts. The average cost estimate per patient for 4F-PCC was similar (approx. $4300) in each cohort., Conclusion: 4F-PCC is an effective but expensive treatment option for those requiring urgent reversal of vitamin K antagonist-induced coagulopathy. However, providers should be conscious of the high costs and questionable efficacy when using 4F-PCC off-label., (© 2019 AABB.)

Oral factor Xa (fXa) inhibitor-related bleeding is a concerning drug safety problem. There is considerable controversy surrounding available reversal strategies. The recently approved reversal agent andexanet alfa has limited data, an unclear safety profile, and imparts a substantial financial burden. This has led to the off-label use of four-factor prothrombin complex concentrates (4F-PCC) for this indication. This study aimed to assess the safety and efficacy of 4F-PCC for the management of major bleeding related to oral fXa inhibitors. This observational, retrospective study included adult patients admitted from 2014 to 2018 who received 4F-PCC (Kcentra ® ) for fXa inhibitor-related major bleeding. Efficacy was assessed using criteria described by Sarode et al. Secondary outcomes included the incidence of thromboembolism, mortality, and a cost analysis comparing 4F-PCC to andexanet alfa for reversal of oral fXa inhibitors. Thirty-one patients received 4F-PCC for major bleeding associated with apixaban (55%) or rivaroxaban (45%). Intracranial hemorrhage (58%) and pericardial effusion (16%) accounted for the majority of bleeding events. Most patients received a single weight-based 4F-PCC dose of 25 units/kg (38.7%) or 50 units/kg (51.6%). Effective hemostasis was achieved in 80.6% of patients. Five patients (16%) died due to acute bleeding and no thromboembolic events were observed. Administration of 4F-PCC was effective for most patients requiring emergent reversal of anticoagulation with apixaban or rivaroxaban and was associated with a low risk of thromboembolic events. Considerable cost differences limit the use of andexanet alfa and may warrant further study of 4F-PCC for fXa inhibitor reversal.

Objective: To compare the costs and clinical consequences of treating mild-to-moderate joint bleeds with recombinant activated factor VII (rFVIIa) versus plasma-derived activated prothrombin complex concentrate (pd-aPCC) in pediatric patients with hemophilia A with inhibitors in Mexico., Methods: A cost-effectiveness model was developed using TreeAge Pro v14.2.2 software (licensed in the USA) and adapted from a previously published model, with adjustments to reflect local clinical practice. Expert opinion was sought regarding patients' clinical management and resource utilization in Mexico to ensure that the current model was appropriate and relevant. The model compared rFVIIa and pd-aPCC for the treatment of mild-to-moderate joint bleeds in children <14 years old (assumed average weight: 30 kg). The analysis outcome was incremental cost per resolved mild-to-moderate joint bleed. One-way sensitivity analysis and probabilistic sensitivity analysis were used to assess specific assumptions and to address any uncertainty in the model., Results: The cost of treating mild-to-moderate joint bleeds was lower for rFVIIa versus pd-aPCC after 7 days (MX$105,581 vs. MX$132,024), assuming complete bleed resolution. After 48 hours, rFVIIa was associated with an 8% improvement in bleed resolution versus pd-aPCC, resulting in cost savings of MX$16,754. Probabilistic sensitivity analysis indicated that rFVIIa treatment was more cost-effective than pd-aPCC in 67% (at 7 days) and 72% (at 48 hours) of Monte Carlo simulations., Conclusion: Accounting for model uncertainty, rFVIIa provided cost savings over pd-aPCC for the Mexican public health care payer in the management of mild-to-moderate joint bleeds in pediatric hemophilia A with inhibitors., (Copyright © 2018 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Objectives: Hemophilia is a rare genetic disease, characterized by uncontrolled bleeding. Injections of clotting factor are the principal are the principal treatment. This drug is very expensive. The objectives of this study are to determine the cost of clotting factor for in patients and the factor impacting this cost., Methods: A retrospective study was carried on hemophiliac in patients between 1 January 2014 and 31 December 2015 in Cochin hospital and having received at least an injection of clotting factor during their hospitalization. A collection of clinical data and treatments received during the hospitalization was realized for every patient., Results: Fifty-one patients were included in the study with a total of 68 hospitalizations. The median cost of clotting factors by hospitalization was 16,908€. The median part of clotting factors on the total cost of the hospitalization was 68.2%. The cost of factors by stay was higher for the severe haemophiliacs (P=0.015) and for the major surgeries (P<0.0001). The daily median cost of clotting factors was 3124€. This cost was higher at the haemophiliacs B (P=0.0112), the severe haemophiliacs (P<0.0001) and the haemophiliacs with inhibitor (P=0.0053)., Conclusions: Clotting factors represent the most part of the cost of hospitalization of a haemophiliac. Their cost in hospitalization varies according to many factors. It may evolve with the arrival of long-acting clotting factors., (Copyright © 2018 Académie Nationale de Pharmacie.

Purpose: Results of a comparison of blood product use and cost outcomes with use of 3-factor versus 4-factor prothrombin complex concentrate (PCC) for indications other than warfarin reversal are presented., Methods: Consecutive patients who received 3-factor PPC (PCC3) or 4-factor PCC (PCC4) for non-warfarin-related indications at 2 U.S. hospitals during a 19-month period were identified. The primary outcome was in-hospital blood product use, with a focus on plasma use. Total hemostasis costs, intensive care unit (ICU) and hospital lengths of stay, and other outcomes were evaluated., Results: Indications for PCC3 use ( n = 118) or PCC4 use ( n = 64) included intraoperative bleeding, nonintraoperative bleeding, coagulopathy of liver disease, and reversal of direct-acting oral anticoagulant effects. The proportion of patients who received plasma was 56.8% with PCC3 use versus 53.1% with PCC4 use ( p = 0.643); the corresponding median volumes of plasma received were 638 mL (interquartile range [IQR], 550-1,355 mL) and 656 mL (IQR, 532-1,136 mL), respectively. The median total hemostasis costs were $5,559 (IQR, $3,922-$8,159) with PCC3 use and $7,771 (IQR, $6,366-$9,205) with PCC4 use ( p < 0.001)., Conclusion: PCC3 use and PCC4 use were associated with similar blood product use, ICU length of stay, hospital length of stay, and in-hospital mortality when given for non-warfarin-related indications. However, relative to PCC3 use, PCC4 use was associated with an increase in costs that was primarily due to drug costs., Competing Interests: DisclosuresDr. Patanwala has previously received grant funding from CSL Behring; he has declared no other potential conflicts of interest.

Background: Prophylaxis with clotting factor replacement products is recommended by the Medical and Scientific Advisory Council of the National Hemophilia Foundation as the optimal therapy for the prevention of bleeding episodes in individuals with severe hemophilia A or B (< 1 IU per dL endogenous factor VIII or factor IX activity, respectively). Prophylaxis is associated with an improved health-related quality of life and has been shown to be cost-effective compared with on-demand therapy. However, the overall cost of treatment remains high, particularly among patients with a greater propensity to bleed. The overall value of hemophilia treatments and their associated benefits, measured in quality-adjusted life-years (QALYs), and dollar costs compared with other interventions can be evaluated through the use of cost-utility analyses (CUAs). Previous CUA studies in hemophilia have focused primarily on patients with more severe forms of hemophilia and on prophylaxis compared with on-demand treatment. However, to our knowledge, no studies to date have utilized QALYs as a standardized outcome measure to systematically evaluate the relative cost-effectiveness of current hemophilia treatment options., Objective: To systematically review the CUA literature of hemophilia treatments and demonstrate the challenges in producing cost-utility evidence compared with other rare diseases., Methods: We conducted a systematic literature review using the Tufts Medical Center Cost-Effectiveness Analysis Registry and the National Health Service Economic Evaluation Database for English-language CUAs published from 2000 through 2015 with the search terms hemophilia, haemophilia, factor VIII, or factor IX. Two trained reviewers independently reviewed every study to extract relevant data. Incremental cost-effectiveness ratios were converted to 2014 U.S. dollars using exchange rates for currency conversion and the Consumer Price Index to adjust for inflation., Results: Our search yielded 52 studies, 11 of which met our inclusion criteria. The cost-effectiveness of hemophilia treatments varied widely based on variations in the study designs, including differences in time horizon, discount rates, and medical interventions., Conclusions: We found the cost-effectiveness of hemophilia treatments to be broadly comparable to that of other orphan drugs. Improved standardization of future CUA studies will be important for further evaluation of the cost-effectiveness of hemophilia treatments., Disclosures: This research was funded by Biogen, which provided an unrestricted research grant to the Center for the Evaluation of Value and Risk in Health at Tufts Medical Center.

Background: Hemophilia B requires replacement therapy with factor IX (FIX) coagulation products to treat and prevent bleeding episodes. A recently introduced extended half-life (EHL) recombinant FIX replacement product provided the opportunity to compare the amount of dispensed factor and expenditures for EHL treatment compared with a standard half-life (SHL) product., Objective: To determine factor international units (IUs) dispensed and expenditures associated with switching from nonacog alfa, the most commonly used SHL replacement product, to eftrenonacog alfa, an EHL FIX replacement product., Methods: Two U.S. claims databases were analyzed. A large national specialty pharmacy dispensation claims database was used to identify the number of IUs dispensed and monthly charges for all patients with hemophilia B from April 2015 to June 2016. Truven Health MarketScan Research Databases (January 2010-July 2016) were used to identify IUs and expenditures for patients with claims data for at least 3 months before and after switching from the SHL to the EHL product. Medians for IUs and expenditures are presented to accommodate for skewness of data distribution., Results: The national specialty pharmacy database analysis included 296 patients with moderate or severe hemophilia B (233 on SHL; 94 on EHL). Median monthly factor dispensed was 11% lower (2,142 IU) in the EHL versus SHL cohort over the study period, while individual monthly reductions ranged from 32% to 47% (9,838 IU to 16,514 IU). Using the wholesale acquisition cost, the median per-patient monthly factor expenditures over the 15-month study period were 94% higher ($23,005) for the EHL than for the SHL product. Individual median monthly expenditure differences ranged from 15% ($6,562) to 49% ($19,624). In the Truven database, 14 patients switched from the SHL to the EHL product. The amount of factor dispensed was variable; in the 1-year period before and after the switch from the SHL to the EHL product, mean IUs dispensed decreased by 3,005 IU, while median IUs dispensed increased by 4,775 IU. Factor replacement expenditures were higher after switching from the SHL to the EHL product in each of the 3-month periods examined before versus after the switch., Conclusions: This analysis of real-world data showed that switching from the SHL to the EHL product was associated with higher expenditures. Increased expenditures noted in the first 3 months after switching may be related to initial stocking up of the EHL product, but expenditures were sustained throughout the 1-year period of data analysis. Further analysis of these findings with larger numbers of patients should be explored., Disclosures: This study was sponsored by Pfizer.

Background: Prothrombin complex concentrates (PCCs) are drug products containing varying amounts of vitamin K-dependent coagulation factors II, VII, IX, and X. The evidence comparing 3-factor PCC (3-PCC) versus 4-factor PCC (4-PCC) for warfarin reversal is conflicting. It has been hypothesized that 3-PCC may be less effective than 4-PCC because of relatively lower factor VII content., Study Question: The primary objective of this study was to compare international normalized ratio (INR) reversal between 3-PCC and 4-factor PCC (4-PCC) in warfarin-treated patients. The secondary objectives include comparing blood product use, total reversal costs, and cost-effectiveness between the groups., Study Design: This was a retrospective cohort study conducted in 2 affiliated, academic institutions in the United States. Consecutive adult patients who received 3-PCC or 4-PCC for warfarin reversal were included., Measures and Outcomes: The primary outcome was adequate INR reversal defined as a final INR ≤1.5. Secondary outcomes were the utilization of plasma, red blood cells and platelets, reversal costs, and the cost-effectiveness ratio., Results: There were 89 patients who were included in the overall cohort (3-PCC = 57, 4-PCC = 32). Adequate INR reversal occurred less commonly with 3-PCC (45.6%) compared with 4-PCC (87.5%) (P < 0.001). There was no significant difference in the proportion of patients who received plasma (32% vs. 28%, P = 0.813), red blood cells (37% vs. 47%, P = 0.377), or platelets (16% vs. 28%, P = 0.180) between the 3-PCC and 4-PCC groups, respectively. The median reversal cost of 3-PCC ($3663) was lower than 4-PCC ($5105) (P = 0.001). The cost-effective ratio favored 4-PCC ($5105/87.5% = $5834) compared with 3-PCC ($3663/45.6% = $8033)., Conclusions: Four-PCC was more effective than 3-PCC with regard to INR reversal in patients taking warfarin, but blood product use was similar. Although 4-PCC is associated with increased reversal costs, it may be cost-effective in terms of INR reversal.

Background: Left ventricular assist device (LVAD) recipients undergoing heart transplantation have increased bleeding risk. We compared conventional warfarin reversal with fresh frozen plasma vs 4-factor prothrombin complex concentrate (PCC) and the effect on transfusion requirements, blood bank costs, and clinical outcomes., Methods: A retrospective review identified 60 consecutive LVAD recipients undergoing heart transplantation divided into two groups: 30 (no PCC) received fresh frozen plasma and 30 (PCC) received PCC. Patient characteristics, intraoperative and postoperative transfusion requirements, short-term clinical outcomes, and blood bank costs were compared. PCC association with transfusion requirements was assessed by multivariate linear regression., Results: Patients who received PCC were younger (50 ± 11 vs 57 ± 13 years, p = 0.02), fewer had ischemic cardiomyopathy (23% vs 60%, p = 0.01), had more than one prior sternotomy (7% vs 30%, p = 0.04), and had higher preoperative hemoglobin (11.8 ± 1.8 vs 10.4 ± 1.8 g/dL, p = 0.01). The PCC group had a significantly shorter bypass time (185 vs 217 minutes, p = 0.01), received less fresh frozen plasma (2 vs 5 units, p = 0.03), cryoprecipitate (0 vs 2 units, p = 0.05), and total blood products (9 vs 13.5 units, p = 0.03) intraoperatively, and was less likely to require delayed sternal closure (3% vs 23%, p = 0.05). On multivariate linear regression, PCC was significantly associated with decreased intraoperative transfusion (β = -6.09, p = 0.02). There was no difference in thromboembolic events or in-hospital death. Total blood bank costs were $4,949 for PCC and $3,677 for no PCC (p = 0.01)., Conclusions: Although more costly, PCC reduced transfusion requirements and delayed sternal closure in heart transplant recipients bridged with LVAD, justifying its use over traditional warfarin reversal., (Copyright © 2018 The Society of Thoracic Surgeons.

Published literature suggests that a fixed-dose 4-factor prothrombin complex concentrate (4FPCC) may be efficacious in managing warfarin-associated hemorrhage, however the ideal dose is still unclear. The purpose of this evaluation was to determine the efficacy of fixed-dose 4FPCC in reducing the International Normalized Ratio (INR) to ≤ 1.5 among warfarin patients with need for urgent or emergent anticoagulation reversal. Starting October 2016, our institution changed from standard 4FPCC FDA-labeled dosing based on the patient's presenting INR and weight, to a fixed-dose of 1500 units for all patients requiring urgent or emergent warfarin reversal. We conducted a retrospective evaluation, after implementation, with the primary outcome being the proportion of patients who achieved an INR ≤ 1.5 with a single fixed-dose of 1500 units of 4FPCC. Secondary outcomes assessed included: medication turnaround times, attainment of target INR ≤ 2 or clinical hemostasis (as judged by the prescribing provider), use of rescue doses, thrombotic events, and cost savings. A total of 37 patients were included in the analysis. Almost 75% of patients achieved an INR ≤ 1.5 after a single fixed dose of 1500 units, and 100% of patients achieved an INR ≤ 2. The median pre- and post-dose INRs were 3.06 and 1.32 respectively. Based on this evaluation, the administration of a fixed dose of 1500 units 4FPCC, was shown to be effective in adequately reversing the INR in the majority of patients with minimal thrombotic risks.

Objectives: To determine US societal burden of illness, including direct and indirect costs and annual bleed rate (ABR), for persons with hemophilia B (HB), a rare and debilitating genetic disorder, and to examine associations of hemophilia severity and treatment regimens with costs and ABR., Methods: From 2009 to 2014, the Hemophilia Utilization Group Studies Part Vb collected prospective data from 10 US hemophilia treatment centers. Participants with HB completed initial surveys on sociodemographic characteristics, clinical characteristics, and treatment patterns. During the 2-year follow-up, participants reported bleeding episodes, work absenteeism, and caregiver time quarterly. These data were used to calculate ABR and indirect costs. Direct costs were calculated using 1-year clinical chart records and 2-year dispensing records., Results: Of the 148 participants, 112 with complete medical records and one or more follow-up survey were included. Total mean annual per-person costs were $85,852 (median $20,160) for mild/moderate HB, $198,733 (median $147,891) for severe HB, and $140,240 (median $63,617) for all participants without inhibitors (P < 0.0001). Mean ABR for participants with severe HB on prophylaxis (5.5 ± 7.9 bleeds/y) was almost half that of those treated episodically. Clotting factor and indirect costs accounted for 85% and 9% of total costs, respectively. Compared with episodic treatment, prophylaxis use was associated with 2.5-fold higher clotting factor costs (P < 0.01), low but significantly more missed parental workdays (P < 0.0001) and clinician (P < 0.001) or nursing visits (P < 0.0001), less part-time employment and unemployment, and lower hospitalizations costs (P = 0.17) and ABR (P < 0.0001)., Conclusions: HB is associated with high economic burden, primarily because of clotting factor costs. Nevertheless, prophylaxis treatment leads to clinical benefits and may reduce other nonfactor costs., (Copyright © 2017 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

To report the impact of an inpatient anticoagulation stewardship program at a community hospital to promote optimal anticoagulant use. The anticoagulation team (ACT) stewardship program consists of two clinical pharmacists and hematologists to provide oversight of anticoagulants, high cost reversal agents including prothrombin complex concentrate (PCC, Kcentra™), and heparin-induced thrombocytopenia (HIT) management. Intervention data and number of charts reviewed were collected. Average cost avoidance data was applied to ACT interventions to estimate cost savings. The PCC analysis was conducted via retrospective chart review during the pre-intervention period. Prospective monitoring continued in the post-intervention period to determine the percentage of PCC use within the institution's guidelines or approved by ACT or hematology. A total of 19,445 patient charts were reviewed, and 1930 (10%) contained stewardship opportunity. Of the interventions, 71% were provided to the medical service and 22% to surgical services with acceptance rates of 91 and 83%, respectively. Intervention cost-avoidance calculated to be $694,217. Regarding HIT interventions, 52% of interventions involved pharmacokinetic/pharmacodynamics optimization in 18 patients with suspected or confirmed HIT. Regarding PCC use, 55.8% of PCC orders were considered inappropriate in the pre-invention period versus 2.6% post-intervention. Appropriate PCC doses per month post-intervention were consistent with pre-intervention doses (7.67 vs. 6.73, respectively). The projected annual PCC cost savings is $385,473. The overall estimated financial impact of ACT is $799,690 saved. Implementation of an anticoagulation stewardship program reduced costs and improved clinical outcomes. It is also expected that anticoagulant optimization and provider education improved overall safety.

The immune response to infused factor concentrates remains a major source of morbidity and mortality in the treatment of patients with hemophilia A and B. This review focuses on current treatment options and novel therapies currently in clinical trials. After a brief review of immune tolerance regimens, the focus of the discussion is on preventing bleeding in patients with hemophilia and inhibitors. Recombinant factor VIIa and activated prothrombin complex concentrates are the mainstays in treating bleeds in patients with inhibitors. Both agents have been shown to reduce bleeding episodes to a similar degree when infused prophylactically; however, individual patients may respond better to one agent over the other at any given time. The international immune tolerance trial revealed that a high-dose factor VIII regimen provided significantly better bleeding protection than the low-dose regimen. Given the high cost of treatment and the potential for a high-dose immune tolerance regimen to prevent bleeding in some patients, we discuss how we treat patients to maximize the prevention of bleeds while minimizing cost. Novel approaches to treatment of these patients are in development. These include agents that mimic factor VIII or augment thrombin generation by bypassing the inhibitor, as well as agents that inhibit the natural anticoagulants., (© 2016 by The American Society of Hematology.

Background: Transfusion in patients having cardiac surgery has been associated with increased morbidity, mortality, and costs. This analysis assessed the impact of a rotational thromboelastometry (ROTEM®)- and functional platelet assessment (Multiplate®)-based protocol for bleeding management on perioperative outcomes and costs in patients undergoing cardiac surgery., Methods: This retrospective analysis of the records of all patients who underwent cardiac surgery at the Hesperia Hospital, Modena, Italy, from December 2012 to December 2013 compared outcomes and costs of bleeding management for the two 6-month periods before/after introduction of the ROTEM- and Multiplate-based protocol. Descriptive and correlation analysis were performed as appropriate. Propensity score matching and its correlation analysis were performed., Results: Data from 768 consecutive patients (mean age ~69 years, ~66% male) were included; 50.7% and 49.3% of patients had surgery before and after protocol introduction, respectively. Significantly fewer patients required transfusions of packed red blood cells after the protocol introduction over the 24 hours postsurgery (100 vs. 197 patients; P<0.001) and during ICU stay (134 vs. 221 patients; P<0.001). A significantly greater proportion of patients treated after protocol introduction received prothrombin complex concentrate (31 vs. 16; P<0.05) and fibrinogen concentrate (36 vs. 13; P<0.001). A significantly greater proportion of patients treated after protocol introduction had an ICU stay duration <48 hours (81.5% vs. 71.5%; P<0.001). ROTEM-based bleeding management was associated with a saving of €128,676.23 for the 379 patients undergoing surgery post-protocol introduction (€339.52 per patient)., Conclusions: ROTEM-guided bleeding management in patients undergoing cardiac surgery was cost-effective and associated with an increase of administration of coagulation factor concentrates and a decrease of ICU length of stay.

Background: Hemophilia patients use factor-clotting concentrates (factor VIII for hemophilia A and factor IX for hemophilia B) for improved blood clotting. These products are used to prevent or stop bleeding episodes. However, some hemophilia patients develop inhibitors (i.e., the patient's immune system develops antibodies against these factor concentrates). Hence, these patients do not respond well to the factor concentrates. A majority of hemophilia patients with inhibitors are managed on-demand with the following bypassing agents: recombinant factor VIIa (rFVIIa) and activated prothrombin complex concentrate (aPCC). The recently published U.S. registries Dosing Observational Study in Hemophilia (DOSE) and Hemostasis and Thrombosis Research Society (HTRS) reported higher rFVIIa on-demand use for bleed management than previously described., Objective: To estimate aPCC and rFVIIa prophylaxis costs relative to rFVIIa on-demand treatment cost based on rFVIIa doses reported in U.S. registries., Methods: A literature-based cost model was developed assuming a base case on-demand annual bleed rate (ABR) of 28.7 per inhibitor patient, which was taken from a randomized phase 3 clinical trial. The doses for rFVIIa on-demand were taken from the median dose per bleed reported by the DOSE and HTRS registries. Model inputs for aPCC and rFVIIa prophylaxis (i.e., dosing and efficacy) were derived from respective randomized clinical trials. Cost analysis was from the U.S. payer perspective, and only direct drug costs were considered. The drug cost was based on the Medicare Part B 2014 average sale price (ASP). Two-way sensitivity and threshold analyses were performed by simultaneously varying on-demand ABR, prophylaxis efficacy, and unit drug cost. In addition to studying relative costs associated with on-demand and prophylaxis treatments, relative cost per bleeding episode avoided were also calculated for aPCC and rFVIIa prophylaxis treatments. The prophylaxis efficacy reported in the trials were used to determine the number of bleeding episodes avoided., Results: Based on the median on-demand dose of 695 mcg per kg per bleed, reported by the DOSE registry, the annual rFVIIa on-demand cost was $34,009 per kg of body weight. The annual rFVIIa on-demand cost was $22,020 per kg of body weight when the median dose of 450 mcg per kg per bleed reported by the HTRS registry was considered. The annual cost rose to $38,461 per kg of body weight when the rFVIIa on-demand dose of 786 mcg per kg per bleed among patients infusing an initial dose ≥ 250 mcg per kg was considered. The aPCC (85 units per kg per every other day) and rFVIIa (90 mcg per kg per every day) annual prophylaxis costs were $26,536 and $60,700, respectively. Also, aPCC and rFVIIa prophyaxis treatments were estimated to prevent a total of 20.8 and 12.9 annual bleeding episodes, respectively. When compared with the on-demand dose of 695 mcg per kg per bleed (DOSE registry), the annual aPCC and rFVIIa prophylaxis costs were 21.9% lower and 78.4% higher, respectively. Additionally, aPCC prophylaxis saved $360 per kg for each bleeding episode avoided. rFVIIa prophylaxis cost $2,066 per kg for each bleeding episode avoided. Compared with the on-demand dose of 450 mcg per kg per bleed (HTRS registry), aPCC and rFVIIa prophylaxis costs were 20.5% and 174.9% higher, respectively. In this case, aPCC and rFVIIa prophylaxis treatment costs were $217 per kg and $2,995 per kg, respectively, for each bleeding episode avoided. aPCC and rFVIIa prophylaxis costs were 31.0% lower and 57.8% higher, respectively, when compared with the rFVIIa on-demand dose of 786 mcg per kg per bleed, among patients infusing an initial dose ≥ 250 mcg per kg (HTRS registry). In this case, aPCC prophylaxis saved $573 per kg for each bleeding episode avoided, while rFVIIa prophylaxis costs $1,724 per kg for each bleeding episode avoided. Results of the 2-way sensitivity analyses were robust in the majority of the scenarios considered., Conclusions: aPCC prophylaxis may be cost saving for managing hemophilia patients with inhibitors who bleed frequently and infuse significant quantities of rFVIIa on-demand.

Aims: Haemophilia is a rare genetic disease that hinders blood clotting. We aimed to review model-based cost-effectiveness analyses (CEAs) of haemophilia treatments, describe the sources of clinical evidence used by these CEAs, summarize the reported cost-effectiveness of different treatment strategies, and assess the quality and risk of bias., Methods: We conducted a systematic literature review of model-based CEAs of haemophilia treatments by searching databases, the Tufts Medical Center CEA registry, and grey literature. We summarized and qualitatively synthesized the approaches and results of the included CEAs, without a meta-analysis due the diversity of the studies., Results: 32 eligible studies were performed in 12 countries and reported 53 pairwise comparisons. Most studies analysed patients with haemophilia A rather than haemophilia B. Comparisons of prophylactic versus on-demand treatment indicated that prophylaxis may not be cost-effective, but there was no clear consensus. Emicizumab was generally cost-effective compared with clotting factor treatments and was always dominant for patients with inhibitors. Immune tolerance induction following a Malmö protocol was found to be cost-effective compared to bypassing agents, while there was no consensus for the other protocols. Gene therapies as well as treatment with extended half-life coagulation factors were always cost-effective over their comparators. Studies were highly heterogenous regarding their time horizons, model structures, the inclusion of bleeding-related mortality and quality-of-life impacts. This heterogeneity limited the comparability of the studies. 19 of the 32 included studies received industry funding, which may have biased their results., Limitations: It was not possible to perform a quantitative synthesis of the results due to the heterogeneity of the underlying studies., Conclusion: Differences in results between previous CEAs may have been driven by heterogeneity in modelling approaches, clinical input data, and potential funding biases. A more consistent evidence base and modelling approach would enhance the comparability between CEAs.

Background: Results of a previously published study demonstrated a significant decrease in transfusion requirements and calculated blood loss for pediatric major craniosynostosis surgery, if a ROTEM(®) FIBTEM trigger of <13 mm (early substitution group) was applied as compared to a trigger of <8 mm (conventional group). The aim of this study was a posthoc analysis of the costs for this coagulation management., Methods: The total volume as well as the number of units or bags for all transfused blood products and coagulation factors were recorded for each case. The number of laboratory and point-of-care coagulation tests was also analyzed. Total blood product costs were calculated according to the local prices per unit., Results: The total cost for all transfused/administered blood products/coagulation factors per patient was a median of 1023EUR (IQR 850EUR-1058EUR) in the early substitution group as compared to a median of 910EUR (IQR 719EUR-1351EUR) in the conventional group (P = 0.81). No difference in the number of coagulation tests performed was observed., Conclusion: In this study, the use of a higher fibrinogen trigger was not linked to a significant increase in total costs for transfused blood products and coagulation factors, and may offer an economically equivalent approach to coagulation management., (© 2015 John Wiley & Sons Ltd.)

Introduction: Fresh frozen plasma (FFP) is a frequently used human blood product to reverse the effects of vitamin K antagonists. While FFP is relatively economical, its large fluid volume can lead to hospitalization complications, therefore increasing the overall cost of use., Materials & Methods: A recently published article by Sarode et al., in Circulation, described the rate of volume overload associated with FFP use for reversal of vitamin K antagonists. This condition, described as transfusion-associated circulatory overload, has a defined rate of intensive care admission, which also has a well-reported average cost. The additional monetary value of intensive care unit admission and caring for fluid overload is then compared to the cost of another product, four-factor prothrombin complex concentrates, which does not, as per the Sarode paper, result in fluid overload., Results: The increased costs attributed to FFP-associated fluid overload for vitamin K antagonist reversal partly defrays the increased upfront cost of four-factor prothrombin complex concentrates., Discussion: FFP is commonly used to acutely reverse the effects of vitamin K antagonists. However, its use requires significant time for infusion, may lead to fluid overload, and is not fully effective in compete anticoagulation reversal. One alternative therapy for anticoagulant reversal is use of prothrombin complex concentrates, which are rapidly infused, are not associated with fluid overload, and are effective in complete reversal of coagulation measurements. This should be considered for patients with acute bleeding emergencies.

Estimates of preference-weighted health outcomes or health state utilities are needed to assess improvements in health in terms of quality-adjusted life-years. Gains in quality-adjusted life-years are used to assess the cost-effectiveness of prophylactic use of clotting factor compared with on-demand treatment among people with hemophilia, a congenital bleeding disorder. Published estimates of health utilities for people with hemophilia vary, contributing to uncertainty in the estimates of cost-effectiveness of prophylaxis. Challenges in estimating utility weights for the purpose of evaluating hemophilia treatment include selection bias in observational data, difficulty in adjusting for predictors of health-related quality of life and lack of preference-based data comparing adults with lifetime or primary prophylaxis versus no prophylaxis living within the same country and healthcare system.

Hemophilia A and B are chronic inherited bleeding disorders that together rank as one of the most expensive chronic diseases in the United States. Factor replacement products, which are the mainstay of treatment, are among the most expensive therapies, with a total annual cost of more than $250,000 per adult patient in the United States. Indirect costs also contribute to the economic burden and include lost productivity, caregivers' unpaid costs, and hemophiliarelated disability. Advances in hemophilia care have resulted in longer survival and a growing patient population, greater complexity in management of the disorder, and rising treatment costs. The establishment of federally recognized Hemophilia Treatment Centers has decreased costs and improved patient outcomes and quality of life by promoting outpatient, preventive, and homebased care. Successful collaboration among providers and managed care programs can improve outcomes and decrease costs for the delivery of hemophilia services.

Background: Hip fractures require operation within 36-48 h, and they are most common in the elderly. A high International Normalized Ratio should be corrected before surgery. In the current study, we analyzed the budget impact of various warfarin reversal approaches., Methods: Four reversal strategies were chosen for the budget impact analysis: the temporary withholding of warfarin, administration of vitamin K, fresh frozen plasma (FFP), and a four-factor prothrombin complex concentrate (PCC)., Results: We estimated that, annually, 410 hip fracture patients potentially require warfarin reversal in Finland. The least costly treatment was vitamin K, which accounted for €289,000 in direct healthcare costs, and the most costly treatment option was warfarin cessation, which accounted for €1,157,000. In the budget impact analysis, vitamin K, PCC and FFP would be cost-saving to healthcare compared with the current treatment mix., Conclusion: The various warfarin reversal strategies have different onset times, which may substantially impact the subsequent healthcare costs.

One important complication of patients with severe haemophilia A is the formation of inhibitory antibodies to factor VIII (FVIII). Immune tolerance induction (ITI) is the treatment of choice for patients with inhibitors, but this approach is successful in about 60% of patients. Treatment of acute bleeding in patients with inhibitors is one of the greatest challenges in haemophilia management and is costly. Bypassing agents are the mainstay of treatment in these patients. The aims of this study were to review the most recent publications concerning the costs of inhibitor treatment. We conducted a literature review using PubMed which yielded 63 papers analysing the costs of inhibitor management of which 12 were suitable for our study. Four of eight studies supported the use of activated prothrombin complex concentrate (aPCC) with lower costs, but the remaining four studies showed that recombinant factor VIIa (rFVIIa) had a lower average treatment cost. Of four ITI studies, two supported lifelong cost-effectiveness of ITI vs. bypassing agents and the remaining two papers showed a high cost of inhibitor treatment. Dosages, time between onset of bleeding and treatment, patient characteristics and the price of drugs are some of the important issues that should be considered for further studies., (© 2015 John Wiley & Sons A/S.

Objective: To evaluate the health system costs among patients with hemophilia A and B with and without inhibitors over 5 years., Methods: This was a retrospective, observational study utilizing medical and pharmacy electronic medical records and administrative encounters/claims data tracking US patients between 2006-2011. Patients with diagnosis codes for hemophilia A and B were identified. Patients with inhibitors were characterized by utilization of bypassing agents activated prothrombin complex concentrate or factor VIIa on two or more distinct dates. Severity was classified as mild, moderate, or severe based on laboratory tests of clotting factor., Results: There were 160 hemophilia A patients and 54 hemophilia B patients identified. From this group, seven were designated as patients with inhibitors (five with hemophilia A and two with hemophilia B). Hemophilia A patients without inhibitors reported 65 (41.9%) as being severe, 19 (12.3%) as moderate, and 71 (45.8%) as mild. Hemophilia B patients without inhibitors reported nine (17.3%) had severe, 13 (25.0%) had moderate, and 30 (57.7%) had mild hemophilia. All patients with inhibitors had been hospitalized in the previous 5 years compared to 64 (41.3%) with hemophilia A without inhibitors and 22 (42.3%) with hemophilia B without inhibitors. The median aggregate cost per year (including factor and health resource use) was $325,780 for patients with inhibitors compared to $98,334 for hemophilia A patients without inhibitors and $23,265 for hemophilia B patients without inhibitors., Conclusions: The results suggest that, while the frequency of inhibitors within the hemophilia cohort was low, there was a higher frequency of hospitalizations, and the associated median aggregate costs per year were 3-fold higher than those patients without inhibitors. In contrast, hemophilia B patients experience less severe disease and account for lower aggregate yearly costs compared to either patients with hemophilia A or patients with inhibitors.

The high cost of clotting factor concentrate (CFC) used to treat haemophilia and von Willebrand disease (VWD) attracts health plans' attention for cost management strategies such as disease management programmes (DMPs). In 2004, Indiana's high risk insurance health plan, the Indiana Comprehensive Health Insurance Association, in partnership with the Indiana Hemophilia and Thrombosis Center developed and implemented a DMP for beneficiaries with bleeding disorders. This report evaluates the effectiveness of the DMP 5 years post implementation, with specific emphasis on the cost of CFC and other medical expenditures by severity of disease. A pre/post analysis was used. The main evaluation measures were total cost, total outpatient CFC IU dispensed and adjusted total outpatient CFC cost. Summary statistics and mean and median plots were calculated. Overall, 1000 non-parametric bootstrap replicates were created and percentile confidence limits for 95% confidence intervals (CI) are reported. Mean emergency department (ED) visits and mean and median duration of hospitalizations are also reported. The DMP was associated with a significant decrease in mean annualized total cost including decreased CFC utilization and cost in most years in the overall group, and specifically in patients with severe haemophilia. Patients with mild and moderate haemophilia contributed little to overall programme expenditures. This specialty health care provider-administered DMP exemplifies the success of targeted interventions developed and implemented through a health care facility expert in the disease state to curb the cost of specialty pharmaceuticals in conditions when their expenditures represent a significant portion of total annual costs of care., (© 2014 John Wiley & Sons Ltd.)

Coagulopathy is a defined barrier for organ donation in patients with lethal traumatic brain injuries. The purpose of this study was to document our experience with the use of prothrombin complex concentrate (PCC) to facilitate organ donation in patients with lethal traumatic brain injuries. We performed a 4-year retrospective analysis of all patients with devastating gunshot wounds to the brain. The data were analyzed for demographics, change in international normalized ratio (INR), and subsequent organ donation. The primary end point was organ donation. Eighty-eight patients with lethal traumatic brain injury were identified from the trauma registry of whom 13 were coagulopathic at the time of admission (mean INR 2.2 ± 0.8). Of these 13 patients, 10 patients received PCC in an effort to reverse their coagulopathy. Mean INR before PCC administration was 2.01 ± 0.7 and 1.1 ± 0.7 after administration (P < 0.006). Correction of coagulopathy was attained in 70 per cent (seven of 10) patients. Of these seven patients, consent for donation was obtained in six patients and resulted in 19 solid organs being procured. The cost of PCC per patient was $1022 ± 544. PCC effectively reveres coagulopathy associated with lethal traumatic brain injury and enabled patients to proceed to organ donation. Although various methodologies exist for the treatment of coagulopathy to facilitate organ donation, PCC provides a rapid and cost-effective therapy for reversal of coagulopathy in patients with lethal traumatic brain injuries.

Background: Haemophilia is a rare hereditary haemorrhagic disease that requires regular intravenous injections of clotting factor (CF) concentrates. This study sought to estimate the health and economic burden of haemophilia in Belgium. This is the first study of its type to be conducted, and reflects the Belgian authorities' growing interest for haemophilia as part of their priority planning for rare and chronic diseases., Methods: A probabilistic model was developed in order to estimate the lifetime haemophilia burden for the 2011 birth-year Belgian cohort. The health burden was initially expressed in terms of disability-adjusted life years (DALYs), the number of healthy life years lost due to living with disability and dying prematurely. An incidence perspective was used in line with World Health Organization recommendations. The economic burden calculated from direct and indirect haemophilia-related costs was expressed in euros. Data were drawn from the literature if none were available from federal institutions or health insurance. Disability weights for DALY calculation were derived using generic quality-of-life tools such as SF-6D from the SF-36 (36-item Short-Form Health Survey; for adults) and KINDL (generic quality-of-life instrument; for children) compared to population norms. Analyses were stratified according to haemophilia type and severity., Results: In Belgium, haemophilia resulted in 145 undiscounted and unweighted DALYs in total (95% credible interval [CrI] = 90-222), which represents an average of 11 DALYs per incident case with haemophilia (95% CrI = 8-15) during his life, varying according to haemophilia severity (17 DALYs for severe haemophilia, 12 DALYs for moderate, and 4 DALYs for mild). Mean total lifetime costs reached €7.8 million per people with haemophilia, 94.3% being direct costs and 5.7% indirect costs. Clotting factors accounted for 82.5% of direct costs., Conclusions: Haemophilia represents both an economic and health burden, especially regarding individual health on an individual patient level. Initiatives to counteract this burden should be clearly identified and given full support, as this burden is likely to increase in the future, especially from an economic perspective. Our study may also contribute towards a better global evaluation of haemophilia in the future.

Background: In Italy, the supply of plasma-derived medicinal products funded by the National Health Service can be through public healthcare facilities, accredited pharmacies or toll fractionation agreements between Regions and the manufacturer. Pharmaceutical public expenditure includes the supply related to the first two channels and costs can significantly vary because of channel-specific price reductions. This paper describes 2011 public expenditure for plasma-derived medicinal products purchased on the market, as well as the cost analysis per active substance., Materials and Methods: Analysis of the usage of plasma-derived medicinal products and of the related expenditure in public facilities has been carried out using medicinal product traceability data. The analysis related to the accredited pharmacies channel has been carried out using quantities for every medicinal package recorded by Pharmacy Associations and applying reference prices in force on March 1(st), 2012 as well as discounts for the accredited pharmaceutical expenditure imposed by law., Results: At national and regional level, total and total per capita expenditures on plasma-derived medicinal products by market channel and funded by the National Health Service are shown. Analysis was conducted considering the active substances in three groups: substances included in toll fractionation agreements, recombinant coagulation factors, and other substances not included in toll fractionation agreements. In 2011, the national expenditure estimate for plasma-derived and recombinant medicinal product acquisition on the market was about € 535 million., Discussion: The purchased volumes and mean purchased prices per unit of each substance have a significant influence on the observed regional variability of the pharmaceutical public expenditure. A strategy of regional comparison aimed at both sharing a national range of reference for purchase prices and evaluating modalities for centralised purchasing is desirable.

The increasing intensity of treatment, the widespread adoption of factor VIII and IX prophylaxis and increasing usage over the past decade have led to haemophilia becoming an almost uniquely expensive condition to treat. The average adult with severe haemophilia A in the UK used 250,000 IU of factor VIII in 2011/2012, at a cost in excess of £ 100,000 p.a. The cost to the end-user may be considerably higher than this for some US patients supplied by home care companies with high on-costs. This has led to a high level of administrative scrutiny of treatment and an imperative to procure clotting factor concentrates more efficiently and collectively. National procurement schemes have run successfully in various countries and will become commoner. The UK system of procurement is described. This system, following EU procurement rules, evaluated products technically and by price. The price of bioequivalent products was determined by reverse e-auction. Considerable cost reductions were achieved whilst retaining all suppliers and maintaining a degree of prescribing freedom. Elements of this system could be more widely applied., (© 2013 John Wiley & Sons Ltd.)

Severe haemophilia results in increased mortality and poorer quality of life. Factor prophylaxis leads to a more normal life, but is very costly; most of the cost is due to the high cost of replacement factor. Despite its high cost, factor prophylaxis has been adopted throughout the developed world--even in different health care systems. We argue that there are at least five possible reasons why societies may value factor prophylaxis despite its cost: (i) it is directed towards an inherited disease, (ii) the treatment is largely directed towards children, (iii) the disease is rare and the overall cost to society is small, (iv) the treatment is preventative, and v) the high cost is largely the result of providing safe products. In an era of rising health care costs, there is a strong research agenda to establish the factors that determine the value of expensive therapies for rare diseases like haemophilia., (© 2012 Blackwell Publishing Ltd.)

There is lack of evidence-based recommendations or clear-cut consensus regarding the clinical and economic utility of regular prophylaxis started in adulthood, with the aim of keeping the clinical situation from getting worse by prevention of further bleeds contributing to increasing musculo-skeletal or other morbidity in haemophilia. Such a prophylaxis program has been shown in relatively small cohorts to be effective in reducing bleeding occurrence, with a variable effect on the joint status, but with significantly higher factor consumption and consequently higher costs than on-demand therapy. There has been no attempt to identify subsets of patients who may benefit from "tertiary" prophylaxis more than others, for example, due to their bleeding phenotype and/or requirements for product issued on-demand or to identify the dosage that provides the optimal balance of clinical benefit and cost effectiveness. This article reviews the published literature on prophylaxis started beyond the age of 18 years, the barriers to the uptake of prophylaxis programs particularly in adults and highlights areas in need of further research., (© 2012 Blackwell Publishing Ltd.)

The aim of this study was to determine the clinical conditions of patients with haemophilia within Europe as recommended by the European Commission. In this multicentre, cross-sectional, ambispective study, conducted within 21 European countries patients' clinical data were collected, amongst others haemophilia type, severity, treatment pattern, use of factor products, bleeding, orthopaedic joint scores and infections. A total of 1400 patients, 84.3% with haemophilia A and 15.7% with haemophilia B were enrolled by 42 centres between 2004 and 2006. Thereof, 417 were children (30.0%) and 983 were adults (70.0%). About 70% of patients had severe factor deficiency (<1%). More than half of the adults were carriers of chronic infections (12.6% HIV, 55.8% HCV), compared to only 3.8% children (no HIV, 2.9% HCV). Patients were grouped according to per capita amount of clotting factor used in patients' region of residence in 2005: region 1: >5 IU; region 2: 2-5 IU; region 3: <2 IU. Paediatric and adult patients in region 3 had median numbers of three and eight joint bleeds, respectively, with worse joint scores compared to region 1 with zero and one bleed. Prophylactic therapy was used in only 31.3% children and 8.9% adults with severe haemophilia in region 3 compared to 93.7% and 54.1%, respectively, in region 1. Statistical analysis revealed that residence in areas with low factor consumption/availability is the most prominent risk factor for joint disease. Access of European patients with haemophilia to optimal care with safe factor VIII concentrates is limited and depends on the region of residence., (© 2012 Blackwell Publishing Ltd.)

Although individuals with haemophilia have benefited from advances and the availability of safe, effective factor replacement products, high treatment costs and insurance coverage limits remains a significant concern among persons with this disease. Many uninsured haemophiliacs turn to emergency rooms for treatment and/or patient assistance programmes for treatment of a bleed or injury. However, neither of these options is a sustainable solution for managing the care of patients with this costly disease. This study was conducted to examine the use of factor assistance programmes and estimate annual amounts of factor dispensed by each programme along with their associated costs. Retrospective review of pharmacy and medical record of all patients who attended the Gulf States Hemophilia and Thrombophilia Center, and who were enrolled in any factor assistance programme(s) between January 2007 and December 2010 was performed. During the 4-year observation period, approximately 19% of the centre's haemophilia patient population was enrolled and received free factor products from at least one patient assistance programme. In addition, approximately 9.1 million dollars (US) worth of factor replacement therapy was donated to our patients during the study time. Although assistance programmes have helped many uninsured individuals with haemophilia to receive free factor products, they are not an enduring answer to the insurance problems many of our patients face. More effort needs to be focused on how to effectively manage uninsured persons with haemophilia to ensure that their health care and treatment needs are adequately met., (© 2011 Blackwell Publishing Ltd.)

Introduction: Several studies suggest that recombinant activated factor VII (rFVIIa) is more cost-effective than plasma-derived activated prothrombin complex concentrate (pd-aPCC) in haemophilia with inhibitors. However, most do not consider differences between treated patients. This study compared the pharmacoeconomics of rFVIIa versus pd-aPCC treatment of mild to moderate bleeds in inhibitor patients, taking co-variables into account., Methods: The HemoRec and HemIS registries capture exhaustive bleeding data in inhibitor patients in the Czech Republic. For each bleed, patient and bleed characteristics, treatment outcomes and bypassing agent use were retrospectively analysed, and direct costs of care per bleed calculated. Generalised Linear Model regression methods with cluster effect were employed to account for the possibility of several bleedings from the same patient., Results: There were 108 and 53 mild to moderate bleeds in the rFVIIa and pd-aPCC groups, respectively. Although re-bleeding rates were similar in both groups, deeper analyses revealed significant differences in time to bleed resolution: 93.8% of bleeds treated with rFVIIa were resolved within ≤ 12 h, versus 60.4% with pd-aPCC (P < 0.001). Mean total cost/bleed was lower with rFVIIa (336,852 [median, 290,696] CZK; €12,760 [11,011]) than pd-aPCC (522,768 [341,310] CZK; €19,802 [12,928]) (P = 0.002). Results were maintained after controlling for potential co-variables (bleed nature, time to treatment, target joints)., Conclusions: The lower total treatment costs per bleed with rFVIIa than pd-aPCC suggest that first-line rFVIIa is more cost-effective than pd-aPCC in mild to moderate bleeds. Time to bleed resolution was also significantly shorter with rFVIIa. These results were maintained when controlled for potential confounders., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Patients with hemophilia and high titers of inhibitors are hard to treat during bleeding events and consequently are more likely to incur high treatment costs and to experience deterioration in quality of life. We report here the case of a boy with hemophilia A and high titers of inhibitors who responded well to prophylactic activated prothrombin complex concentrate (APCC) treatment. Previously, he had to be hospitalized frequently because of painful bleeding of target joints of the knee and ankle. At the age of 4 years and 3 months, APCC prophylaxis at a dose of 60 U/kg, three times a week, was initiated together with on-demand therapy with recombinant factor VIIa. This reduced the frequency and severity of bleeding and ended the need for hospitalization. This, together with a decreased requirement for bypass agents, APCC treatment significantly reduced the cost of treatment for this patient.
