Abstract
Iron deficiency anemia is among the most frequent causes of disability. Intravenous iron is the quickest way to correct iron deficiency, bypassing the bottleneck of iron intestinal absorption, the only true mechanism of iron balance regulation in human body. Intravenous iron administration is suggested in patients who are refractory/intolerant to oral iron sulfate. However, the intravenous way of iron administration requires several precautions; as the in-hospital administration requires a resuscitation service, as imposed in Europe by the European Medicine Agency, it is very expensive and negatively affects patient's perceived quality of life. A new oral iron formulation, Sucrosomial iron, bypassing the normal way of absorption, seems to be cost-effective in correcting iron deficiency anemia at doses higher than those usually effective with other oral iron formulations. In this multicentric randomized study, we analyze the cost-effectiveness of intravenous sodium ferrigluconate vs oral Sucrosomial iron in patients with iron deficiency anemia refractory/intolerant to oral iron sulfate without other interfering factors on iron absorption.

The use of intravenous iron in pregnancy: for whom and when? A survey of Australian and New Zealand obstetricians. BMC Pregnancy Childbirth 2020; 20:665. [PMID: 33148203 PMCID: PMC7640437 DOI: 10.1186/s12884-020-03363-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 10/27/2020] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Iron deficiency anaemia in pregnancy (IDAP) affects 11-18% of Australian pregnancies and is associated with adverse perinatal outcomes. National prescribing data suggests the use of intravenous iron in pregnancy is increasingly common. This study aimed to: 1) Establish the current patterns of intravenous iron use by Fellows of the Royal Australian and New Zealand College of Obstetricians (FRANZCOG) when treating iron deficiency and IDAP including immediately postpartum and; 2) Assess FRANZCOG opinions regarding potential trial of intravenous iron for first-line treatment of IDAP. METHODS An online survey of RANZCOG Fellows practicing obstetrics was distributed in September 2018. Results were analysed descriptively and responses compared by clinician demographics using Chi-squared testing. RESULTS Of 484 respondents (21% of FRANZCOG), 457 were currently practicing obstetrics. Most prescribed intravenous iron in pregnancy (96%) and/or postpartum (85%). Most intravenous iron was prescribed for IDAP (98%) rather than iron deficiency without anaemia (53%), and for IDAP most commonly second-line to failed oral iron supplementation and first-line in special circumstances (59%). Intravenous iron prescribing was associated with shorter time since FRANZCOG completion (p = 0.01), public hospital practice (p = 0.008) and higher hospital birth numbers (p = 0.01). Most respondents (90%) would consider a randomised controlled trial of first-line intravenous iron for IDAP, although views on appropriate thresholds differed. CONCLUSIONS Almost all respondents prescribed intravenous iron for IDAP, and while mostly used for second-line treatment over half sometimes used it first-line. With accelerating intravenous iron use, further research is required into its optimal use in pregnancy, recognizing important clinical outcomes and cost effectiveness.

Racial/ethnic and gender disparities in the use of erythropoiesis-stimulating agents and blood transfusions: cancer management under Medicare's reimbursement policy. J Manag Care Spec Pharm 2020; 26:1477-1486.

Abstract
BACKGROUND: Because of increasing safety concerns related to erythropoiesisstimulating agents (ESAs), the Centers for Medicare & Medicaid Services issued a Medicare reimbursement policy change regarding these medications in cancer patients. However, the policy established an absolute hemoglobin or hematocrit threshold to qualify for reasonable use but did not take the effect of gender and racial/ethnic differences in hemoglobin levels into consideration. OBJECTIVE: To examine disparities in the use of ESAs and blood transfusions after the Medicare policy change. METHODS: This study was an exploratory treatment effectiveness study and used the SEER-Medicare linked database. The treatment group was composed of cancer patients, whereas the control group was composed of chronic kidney disease patients. An interrupted time series design was used to examine the effect of the Medicare policy change on the use of ESAs and blood transfusions in different gender and racial/ethnic groups. RESULTS: The Medicare reimbursement policy change had an immediate effect on reducing the use of ESAs by 50% and increasing the use of blood transfusions by 10%. The immediate effect of the policy change on the monthly utilization of ESAs was 2 times greater in females (60% reduction) than males (30% reduction). Females had a 10% immediate increase in the monthly utilization of blood transfusions after the policy change. The policy change had the same immediate effect of a 50% reduction on the use of ESAs for Whites, African Americans/Blacks, and Latinos. African Americans/Blacks had a 50% immediate increase in the monthly utilization of blood transfusions after the policy change. CONCLUSIONS: Gender and racial/ethnic disparities were associated with the Medicare reimbursement policy change in the use of ESAs and blood transfusions. Thus, future policy considerations should keep biologic differences across gender and racial/ethnic groups in mind. DISCLOSURES: This study was funded by the SPARC Research Grant. The funder had no role in any part of this study. The authors have nothing to disclose.

Abstract
Intravenous iron supplementation is essential in hemodialysis (HD) patients to recover blood loss and to meet the requirements for erythropoiesis and, in patients receiving erythropoietin, to avert the development of iron deficiency. In a recent real-world study, Hofman et al. showed that a therapeutic shift from iron sucrose (IS) to ferric carboxymaltose (FCM) in HD patients improves iron parameters while reducing use of iron and erythropoietin. The objective of this economic analysis is to compare the weekly cost of treatment of FCM vs IS in hemodialysis patients in Italy. The consumption of drugs (iron and erythropoietin) was derived from Hofman’s data, while the value was calculated at Italian ex-factory prices. The analysis was carried on the total patient sample and in two subgroups: patients with iron deficiency and patients anemic at baseline. In addition, specific sensitivity analyses considered prices currently applied at the regional level, simulating the use of IS vs iron gluconate (FG) and epoetin beta vs epoetin alfa. In the base-case analysis, the switch to FCM generates savings of -€12.47 per patient/week (-21%) in all patients, and even greater savings in the subgroups with iron deficiency -€17.28 (-27%) and in anemic patients -€23.08 (-32%). Sensitivity analyses were always favorable to FCM and confirmed the robustness of the analysis. FCM may represent a cost-saving option for the NHS, and Italian real-world studies are needed to quantify the real consumption of resources in dialysis patients.

Abstract
Objectives: Intravenous iron is the recommended treatment for patients with iron deficiency anemia (IDA) where oral iron is ineffective or rapid iron replenishment is required. Two high-dose, rapid-administration intravenous iron formulations are currently available in the UK: iron isomaltoside 1000/ferric derisomaltose (IIM) and ferric carboxymaltose (FCM). An indirect treatment comparison (ITC) recently showed that improvement from baseline hemoglobin was significantly larger with IIM than FCM. The objective was to use the ITC findings to evaluate the cost-effectiveness of IIM versus FCM from the UK healthcare payer perspective.Methods: A patient-level simulation model was developed in R to evaluate the cost per patient experiencing hematological response with IIM versus FCM. The model generated a simulated cohort from parametric distributions of baseline hemoglobin and bodyweight. Changes in hemoglobin were modeled based on data from the ITC, covaried with baseline hemoglobin based on patient-level data from a randomized controlled trial. Posological models of the iron formulations were developed based on the summaries of product characteristics. UK-specific costs were based on healthcare resource groups.Results: The proportion of patients experiencing hematological response was 9.0% higher with IIM relative to FCM (79.0% versus 70.0%), based on modeling of clinically realistic, correlated distributions of baseline hemoglobin and change from baseline hemoglobin. The mean number of infusions needed to administer the required dose was 1.92 with FCM, versus 1.38 with IIM, resulting in costs of £637 and £457 per treated patient with FCM and IIM respectively, corresponding to respective costs of £910 and £579 per responder.Conclusions: The analysis showed that using IIM rather than FCM in patients with IDA was dominant and would reduce the number of iron infusions required to correct iron deficiency, thereby reducing the costs associated with IDA treatment and simultaneously increasing the proportion of patients with IDA experiencing a clinically meaningful hematological response.

Oral Sucrosomial® iron versus intravenous iron for recovering iron deficiency anaemia in ND-CKD patients: a cost- minimization analysis. BMC Nephrol 2020; 21:57. [PMID: 32087684 PMCID: PMC7035732 DOI: 10.1186/s12882-020-01716-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Accepted: 02/10/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Oral iron is recommended as first line treatment of anemia in non-dialysis chronic kidney disease (ND-CKD) patients. Sucrosomial® iron, a new generation oral iron with high absorption and bioavailability and a low incidence of side effects, has shown to be not inferior to intravenous (IV) iron in the replacement of iron deficiency anemia in patients with ND-CKD. Besides the clinical benefit, it is also important to determine the comparative total costs of oral versus IV iron administrations. The aim of this study was to perform a cost-minimization analysis of oral Sucrosomial iron, compared with IV iron gluconate from an Italian societal perspective. METHODS Cost analysis was performed on the 99 patients with ND-CKD and iron-deficiency anemia of the randomized trial by Pisani et al. Human and material resources utilization was recorded during each iron administration. According to study perspective, direct and indirect costs were considered. Costs for each resource unit were taken from official Italian sources. Probabilistic sensitivity analyses were carried out to test the robustness of the results. RESULTS The base case analysis showed an average cost/cycle per patient of € 111 for oral iron and € 1302 for IV iron. Thus, the potential saving was equal to € 1191 per patient/cycle. The sensitivity analysis showed that the most sensitive driver is the time loss by patient and caregivers for the therapy and related-care, followed by the minutes of nursing care and the number of kilometres travelled to reach the referral centre. DISCUSSION This study showed that oral Sucrosomial® iron could offer specific advantages in terms of potential savings, and allowed identifying some implications for future research. Such advantages still persist with the new single dose IV iron formulation available in the market, although to a lesser extent.

Abstract
Introduction Patients with chronic kidney disease on hemodialysis (HD) are at high risk of developing both iron deficiency and iron deficiency anemia (IDA). The administration of intravenous iron therefore represents the standard of care for the management of anemia in this patient setting. Methods A retrospective cohort of 38 HD patients in Italy was analyzed to assess the clinical and economic implications of switching from intravenous ferric gluconate (FG) to ferric carboxymaltose (FCM) on achievement of adequate hemoglobin (Hb) values and iron balance. The total observational period for each patient was 12 months, 6 months before and 6 months after switching to iron FCM. The pharmacoeconomic analysis considered the hospital perspective and the consumption of iron, blood transfusions and erythropoiesis-stimulating agents (ESAs), including healthcare personnel time. Results Switching from FG to FCM in dialysis adult patients with IDA allows a cost reduction per patient/month in the range €14–46, considering the use of biosimilar ESA or originator ESA, respectively. The percentage of patients with Hb target values increased from 63% to 82%, considering the entire observation period. In addition, other clinical parameters (ferritin, transferrin saturation, erythropoietin resistance index) improved after switching from FG to FCM. Conclusion FCM in HD patients was shown to provide a favorable efficacy profile over FG, with a lower cost per patient, mainly driven by a consistent reduction of ESA consumption.

Abstract
Objectives: There is a lack of data in Panama on the potential differences in total healthcare professional (HCP) time between routine administrations of short-acting erythropoietin simulating agents (ESAs) (i.e. epoetin alfa) and continuous erythropoietin receptor activator (CERA) (i.e. methoxy polyethylene glycol-epoetin beta). This study aimed to quantify the HCP time associated with a single administration of epoetin alfa and CERA for the treatment of anemic patients with chronic kidney disease (CKD) on hemodialysis. Methods: This was a multi-center, cross-sectional study, using a time-and-motion methodology. Costs related to HCP time and consumables usage associated with administration of epoetin alfa and CERA were estimated. Results: Based on 60 administrations of either CERA or epoetin alfa, the estimated savings in mean total active HCP time were 2.34 (95% confidence interval = 1.87-2.81) min (-30%) per administration. When extrapolating to a full year's treatment with intravenous ESA, it would require a total of 20.3 (95% CI = 19.90-20.71) h of HCP time for epoetin alfa vs 1.1 (95% CI = 1.01-1.19) h for CERA per patient per year. Estimated savings in active HCP time per patient per year were 19.20 (95% CI = 19.20-19.21) h (-95%). This, in turn, translates into staff cost efficiency that favors Mircera with an estimated annual saving of $78.24 (95% CI = 78.24-78.28) (-95%) per patient. Conclusions: Data from a real-world setting showed that the adoption of CERA could potentially lead to a reduction in active HCP time. Highlights Few comparative data have explored the costs and potential savings of using long-acting erythropoietin-stimulating agents (ESA) instead of short-acting ESAs to treat anemia in CKD patients on hemodialysis. This time-and-motion study shows that use of CERA reduces total healthcare professional time and could represent a save for an institution in a real-world setting in Panama.

Abstract
Aims: The overall cost and health-related quality of life (HRQoL) associated with current treatments for chronic kidney disease (CKD)-related anemia are not well characterized. A systematic literature review (SLR) was conducted on the costs and HRQoL associated with current treatments for CKD-related anemia among dialysis-dependent (DD) patients. Materials and methods: The authors searched the Cochrane Library, MEDLINE, EMBASE, NHS EED, and NHS HTA for English-language publications. Original studies published between January 1, 2000 and March 17, 2017 meeting the following criteria were included: adult population; study focus was CKD-related anemia; included results on patients receiving iron supplementation, red blood cell transfusion, or erythropoiesis stimulating agents (ESAs); reported results on HRQoL and/or costs. Studies which included patients with DD-CKD, did not directly compare different treatments, and had designs relevant to the objective were retained. HRQoL and cost outcomes, including healthcare resource utilization (HRU), were extracted and summarized in a narrative synthesis. Results: A total of 1,625 publications were retrieved, 15 of which met all inclusion criteria. All identified studies included ESAs as a treatment of interest. Two randomized controlled trials reported that ESA treatment improves HRQoL relative to placebo. Across eight studies comparing HRQoL of patients achieving high vs low hemoglobin (Hb) targets, aiming for higher Hb targets with ESAs generally led to modest HRQoL improvements. Two studies reported that ESA-treated patients had lower costs and HRU compared to untreated patients. One study found that aiming for higher vs lower Hb targets led to reduced HRU, while two other reported that this led to a reduction in cost-effectiveness. Limitations: Heterogeneity of study designs and outcomes; a meta-analysis could not be performed. Conclusions: ESA-treated patients undergoing dialysis incurred lower costs, lower HRU, and had better HRQoL relative to ESA-untreated patients. However, treatment to higher Hb targets led to modest HRQoL improvements compared to lower Hb targets.

Abstract
Background The Taiwan Health Insurance Bureau has conducted a bundled payment system for hemodialysis reimbursement since 1995. The maximum dose of erythropoiesis-stimulating agents allowed by insurance is capped at 20 000 U of epoetin or 100 μg of darbepoetin alfa per month. Nephrologists have avoided the use of high dosages of erythropoiesis-stimulating agents to achieve a hemoglobin level of 10 to 11 g/dL by iron supplementation. The clinical impact of these policies on patients' outcomes is unknown. The authors aimed to assess the AIM-HD (Association of Anemia, Iron parameters, and Mortality among the prevalent Hemodialysis patients) Study in Taiwan. Methods and Results The AIM-HD study was conducted based on the Taiwan Renal Registry Data System. From 2001 to 2008, the authors enrolled 42 230 patients undergoing hemodialysis who were older than 20 years and had received hemodialysis for more than 12 months. Patient follow-ups occurred until death or December 31, 2008. During a study period of 8 years, 12 653 (30.0%) patients died. After multivariate adjustment, the authors found that a hemoglobin level <10 g/dL was significantly associated with higher risk for all-cause and cardiovascular deaths. Moreover, a serum ferritin level between 300 and 800 ng/mL and transferrin saturation value between 30% and 50% were associated with the lowest all-cause mortality. Conclusions The authors recommend avoiding a low hemoglobin level and maintaining serum ferritin between 300 and 800 ng/mL and transferrin saturation between 30% and 50%, which were associated with lower risks of all-cause mortality among patients undergoing hemodialysis receiving the restricted erythropoiesis-stimulating agent doses but prompt intravenous iron supplementation in Taiwan.

Abstract
This is a post-hoc analysis evaluating erythropoiesis stimulating agents' (ESA) related costs while using an additional ultrafilter (Estorclean PLUS) to produce ultrapure dialysis water located within the fluid pathway after the treatment with reverse osmosis and before the dialysis machine. Twenty-nine patients (19 treated with epoetin alfa and 10 with darboepoetin alfa) were included in the analysis. We showed to gain savings of 210 € per patient (35 € per patient each month) with epoetin alfa during the experimental period of 6 months, compared to the control period and of 545 € per patient (90 € per patient each month) with darboepoetin alfa. Estorclean PLUS had a cost of 600 € (25 € per month per each patient) and was used for 6 months. Intravenous iron therapy with sodium ferrigluconate had a cost of 0,545 €/62,5 mg. In conclusion, during the experimental period with the use of Estorclean, we obtained global savings of 11 € per patient per month with epoetin alfa and 30 € per patient per month with darboepoetin alfa to treat anemia in dialysis patients.

Abstract
Ferric citrate (FC) has demonstrated efficacy as a phosphate binder and reduces the requirements for erythropoiesis-stimulating agents (ESAs) and intravenous (IV) iron in dialysis patients. We developed a net budgetary impact model to evaluate FC vs. other phosphate binders from the vantage of a large dialysis provider. We used a Markov microsimulation model to simulate mutually referential longitudinal effects between serum phosphate and phosphate binder dose; categories of these defined health states. Health states probabilistically determined treatment attendance and utilization of ESA and IV iron. We derived model inputs from a retrospective analysis of incident phosphate binder users from a large dialysis organization (January 2011-June 2013) and incorporated treatment effects of FC from a phase III trial. The model was run over a 1-year time horizon. We considered fixed costs of providing dialysis; costs of administering ESA and IV iron; and payment rates for dialysis, ESAs, and IV iron. In the base-case model, FC had a net budgetary impact (savings) of +US$213,223/year per 100 patients treated vs. standard of care. One-way sensitivity analyses showed a net budgetary impact of up to +US$316,296/year per 100 patients treated when higher hemoglobin levels observed with FC translated into a 30% additional ESA dose reduction, and up to +US$223,281/year per 100 patients treated when effects on missed treatment rates were varied. Two-way sensitivity analyses in which acquisition costs for ESA and IV iron were varied showed a net budgetary impact of +US$104,840 to +US$213,223/year per 100 patients treated. FC as a first-line phosphate binder would likely yield substantive savings vs. standard of care under current reimbursement.

Abstract
Background: Inpatient costs associated with different erythropoietic-stimulating therapy regimens have not been compared in an oncology setting. Objective: To conduct a cost analysis of different regimens of epoetin alfa (EPO) and darbepoetin alfa (DARB) in an inpatient oncology setting. Methods: A retrospective evaluation of oncology diagnosis-related group discharges during 2003, in 30 community hospitals, identified EPO treatment patterns. Wholesale acquisition costs were determined for patients who received EPO 40 000 units or more once weekly. Potential differences in costs were calculated using conversion ratios for an equivalent EPO dose 3 times weekly or DARB dose once weekly (EPO:DARB ratio 260:1, approximating DARB 150 μg once weekly). A sensitivity analysis was performed using an EPO:DARB ratio of 400:1, approximating DARB 100 μg once weekly (1.5 μg/kg). Results: Among the 1410 EPO doses administered (n = 677 pts.), a dose of 40000 units or more was used 44% of the time (n = 311 pts.), with dosing initiated on average 5.6 days after admission. For these 311 evaluable patients, switching from EPO 40 000 units once weekly to EPO 10 000 units 3 times weekly reduced per-patient and total drug acquisition costs by approximately 50% ($704 vs $359 and $218 938 vs $111 615, respectively). Relative to EPO once weekly, switching patients to DARB resulted in increased drug acquisition costs at the 260:1 conversion and lower costs at the 400:1 conversion. However, EPO 3 times weekly remained the least costly option by 44–63%. The cost-savings realized with EPO 10000 units 3 times weekly increased with longer duration of hospitalization. Conclusions: In an inpatient setting, use of EPO 10000 units 3 times weekly may minimize expenditures associated with treatment of cancer-related anemia using erythropoietic-stimulating therapies.

Abstract
UNLABELLED Anemia in the elderly is often related to a higher prevalence of chronic diseases such as chronic kidney failure, arthritis, and malignancy. Erythropoiesis-stimulating agents (ESAs) have been used for years to effectively treat anemia and when used appropriately can substantially improve the health status and quality of life of older adults. Following the 2008 recession in Greece, the government introduced ESA price control restrictions, but no prescribing restrictions, in an effort to reduce drug expenditure. OBJECTIVE ESA prescribing patterns and treatment costs were analyzed to determine inappropriate or appropriate use of these agents and related health care resources in Greece. METHOD A retrospective register-based drug utilization study was carried out using data from prescriptions dispensed at the public pharmacy of the largest social insurance fund (IKA-ETAM), for patients receiving ESAs over a six-month period. For each patient, demographic data, ESA dosage regimen, treatment indication and cost, prescriber specialty, and prescription origin were recorded. RESULTS A total of 14,387 prescriptions from 6,074 patients (median age 74 years) were reviewed. A substantial number of patients (13.5%) were treated for off-label indications, for which the average cost per patient per indication was higher. ESA dosage/frequency of administration varied but was in accordance with recommendations. The percentage of patients who received innovator and biosimilar erythropoietin (EPO) was 88% and 12%, respectively. CONCLUSION For the optimization of ESA utilization and the reduction of treatment costs, strict ESA prescription monitoring, development of registries, and criteria for off-label indications and biosimilar use in naive patients under the umbrella of risk-sharing agreements should be proposed.

Comparison of Cost-Effectiveness Between Actinomycin D Versus Methotrexate-Folinic Acid in the Treatment of Low-Risk Gestational Trophoblastic Neoplasia. THE JOURNAL OF REPRODUCTIVE MEDICINE 2016; 61:230-234.

Abstract
OBJECTIVE To compare the cost-effectiveness between actinomycin D (Act-D) and methotrexate-folinic acid (MTX-FA) in the treatment of low-risk gestational trophoblastic neoplasia (GTN) in the Thai population. STUDY DESIGN A comparative cost-effectiveness analysis was performed from a societal perspective. A decision tree model was developed comparing 2 alternative treatment options: initial 5-day Act-D and 8-day MTX-FA. Treatment would be switched to another regimen in case of resistance. The outcome of interest is number of days to remission. Clinical data was obtained from our previous study in which Act-D demonstrated 100% remission rates as compared to 73.6% for MTX-FA. Cost of treatment data, which includes chemotherapeutics, accessory medications, laboratory tests, and hospital fees, was obtained from a university hospital. Patient-related travel cost and opportunity cost due to absence from work were also included. All costs were calculated to 2015 base year. RESULT Costs per treatment cycle were $308.01 and $227.20 US dollars (USD) for 5-day Act-D and 8-day MTX-FA, respectively. Expected time toward treatment completion for Act-D was 12.6 days shorter than for MTX-FA. Expected costs toward remission for initial treatment with Act-D and MTX-FA were $1,078.04 and $1,064.56 USD, respectively, i.e., an incremental cost effectiveness ratio (ICER) of $1.07 USD/day of earlier treatment completion. After sensitivity analysis, remission rate of lower than 72% would make initial treatment with MTX-FA more expensive than with Act-D. CONCLUSION Treatment costs of low-risk GTN are almost equal between the 2 treatment options with different time to remission. Initial treatment with MTX-FA is slightly less expensive, but there is longer time to remission. The ICER of initial treatment with Act-D over MTX-FA is $1.07 USD/day of earlier treatment completion.

Abstract
BACKGROUND Patients with end-stage renal disease (ESRD) require phosphate binders for hyperphosphatemia and erythropoiesis-stimulating agents (ESAs) and intravenous (i.v.) iron for anemia. Ferric citrate (FC) is a novel, iron-based phosphate binder that increases iron stores and decreases i.v. iron and ESA usage while maintaining hemoglobin levels, and may decrease the cost of ESRD care. The study objectives were to (1) quantify differences in ESA and i.v. iron usage among ESRD patients receiving FC compared with active control (AC) (sevelamer carbonate and/or calcium acetate) on the basis of data from a 52-week phase III clinical trial and (2) standardize trial data to the general United States (US) ESRD population and calculate the potential impact of FC on ESRD cost/patient/year in the USA. STUDY DESIGN The study was a randomized, controlled clinical trial. SETTING AND POPULATION A total of 441 adult subjects with ESRD who received FC or AC for 52 weeks were included. MODEL, PERSPECTIVE, AND TIMELINE Differences in ESA and i.v. iron usage between the treatment groups were modeled over time using generalized linear mixed models and zero-inflated Poisson models. Trends were modeled via logarithmic curves, and utilization patterns were applied to the general dialysis population to estimate expected resource savings. OUTCOMES Study outcomes were costs saved/patient/year using FC versus AC (US dollars). RESULTS Our model suggests an annual decrease of 129,106 U of ESAs and 1960 mg of i.v. iron per patient in the second year after a switch from AC to FC. Applying 2013 Medicare pricing, this would save $1585 in ESAs and $516 in i.v. iron: a total of $2101/patient/year; these savings would be expected to double for managed care plans. LIMITATIONS The projections were made on 1 year of trial data. CONCLUSIONS Phosphate binding with FC reduces i.v. iron and ESA usage. Given the high cost burden of ESRD, our model demonstrates significant potential cost savings. TRIAL REGISTRATION ClinicalTrials.gov (NCT01191255) http://clinicaltrials.gov/ct2/show/NCT01191255 .

Abstract
BACKGROUND Anaemia is common in patients undergoing major surgery. The current standard of care for patients with low haemoglobin in the peri-operative period is blood transfusion. The presence of preoperative anaemia is associated with an increased likelihood of the patient receiving peri-operative transfusion and worsened outcomes following surgery, more post-operative complications, delayed recovery and greater length of hospital stay. Intravenous iron, if applied in the preoperative setting, may correct anaemia by the time of surgery and reduce the need for blood transfusion and improve outcomes. METHODS/DESIGN PREVENTT is a phase III double-blind randomised controlled trial that will compare the use of intravenous ferric carboxymaltose (dose 1000 mg) with placebo 10-42 days before major open abdominal surgery in 500 patients with anaemia (haemoglobin < 120 g/L). The primary outcome measure will be the need for blood transfusion and secondary endpoints will include post-operative recovery, length of hospital stay, health care utilisation and cost analysis.

Abstract
PURPOSE Medicare Part D prescription benefits cover injected medications, normally covered under Part B, when administered outside of physician offices. Erythropoiesis-stimulating agents (ESAs) used for chronic anemia management in patients with myelodysplastic syndromes (MDS) are commonly injected in a physician office but can be administered safely at home. In this study, we explored out-of-pocket (OOP) costs and receipt of Part D-covered ESAs in Medicare beneficiaries with MDS. MATERIALS AND METHODS Patients with MDS enrolled in Medicare Parts A, B, and D were identified using diagnosis codes from 100% claims from 2006 to 2008. OOP costs for the mean erythropoietin alfa claim were compared for Parts B and D. Multivariable models examined the effect of low-income subsidy (LIS) and other Part D cost sharing on receipt of any ESA and any Part D-covered ESA. RESULTS A total of 13,117 (62.9%) of 20,848 patients received ESAs, but only 1,436 (6.9%) had any Part D claim. OOP payment was $348 under Part D versus $161 under Part B. Among patients with ESA use, those with LIS were 4× more likely to receive Part D ESAs (P < .01). CONCLUSION Few patients with MDS received ESAs through Part D. OOP payments required under Part D were substantially higher than under Part B. Cost sharing, as reflected by LIS receipt, likely affected decisions to prescribe ESAs outside of the physician office. Improved coordination between Part B and D benefits regarding issues of home injection of medications may create incentives that improve patient access and convenience and reduce costs associated with administration.

Abstract
BACKGROUND Anemia is a common complication associated with kidney failure and is marked by poor health and increased risk of morbidity and mortality. There are ongoing concerns with the use of Erythropoietin Stimulating Agents (ESAs) to treat anemia in patients with kidney failure on dialysis. Questions as to their benefits, harms and overall effect on quality of life are still relevant today. Our objective was to systematically review studies evaluating the cost-effectiveness of ESAs in patients with kidney failure on dialysis. METHODS We performed a systematic review of studies determining the cost-effectiveness of ESAs in adult patients on dialysis. Databases, including PubMed, EMBASE, and Cochrane Database of Systematic Reviews, were searched from their establishment until June 2013. Studies that reported an incremental cost-effectiveness ratio of hemoglobin correction strategies based on ESA treatments in comparison to red blood cell transfusions, lower hemoglobin targets, or no ESA treatment were included. RESULTS Seven studies met inclusion criteria. Reported cost/quality-adjusted life-year (QALY) ratios ranged from USD 931-677,749/QALY across five studies comparing ESAs to red blood cell transfusions. There was heterogeneity in results when considering higher hemoglobin targets, with studies finding higher targets to be both dominant and dominated. Mortality, hospitalization, and utility estimates were major drivers. CONCLUSIONS There is substantial variability in the estimates of the cost-effectiveness of using ESAs in the dialysis population. New models incorporating recent meta-analyses for estimates of utility, mortality, and hospitalization changes would allow for a more comprehensive answer to this question.

Abstract
BACKGROUND Epoetin therapy used to treat anemia among ESRD patients has cost Medicare ∼$40 billion. Since January 2011, epoetin has been reimbursed via a new bundled prospective payment system (PPS). Our aim was to determine changes in epoetin dosing and hematocrit levels in response to PPS by different types of dialysis providers. METHODS Data from the USRDS were used to identify 187,591 and 206,163 Medicare-eligible ESRD patients receiving hemodialysis during January 2010 (pre-PPS) and December 2011 (post-PPS). Standardized weekly mean epoetin dose administered pre- and post-PPS and adjustment in dose (titration) based on previous hematocrit level in each facility was disaggregated by profit status, chain membership and size. RESULTS Major declines in epoetin use, dosing and achieved hematocrit levels were observed after PPS. Among the three largest dialysis chains, the decline in standardized epoetin dose was 29% at Fresenius, 47% at DaVita, and 52% at DCI. The standardized weekly epoetin dose among profit and nonprofit facilities declined by 38 and 42%, respectively. Changes in titration patterns suggest that a new hematocrit target of 30-33% was in place after PPS, replacing the erstwhile 33-36% hematocrit target used before PPS. CONCLUSION Historically, important differences in anemia management were evident by dialysis organizational status. However, the confluence of financial incentives bundling epoetin payments and mounting scientific evidence linking higher hematocrit targets and higher epoetin doses to adverse outcomes have culminated in lower access to epoetin and lower doses across all dialysis providers in the first year after PPS.

Abstract
BACKGROUND National guidelines recommend using anemia management protocols to guide treatment. The objective of this study was to determine if an anemia management protocol would improve hemoglobin (Hgb) indices in hemodialysis patients and to measure whether the protocol would reduce the use and cost of darbepoetin alfa (DBO) and intravenous (IV) iron in hemodialysis patients. METHODS An anemia management protocol was created and implemented for hemodialysis patients at our institution. A retrospective observational review of the use of DBO and IV iron as well as changes in Hgb, transferrin saturation and ferritin in 174 patients was conducted 6 months before and after implementation of the anemia protocol. RESULTS The number of Hgb measurements in the target range increased from 44.3 to 46.0% (p = 0.48) after protocol implementation. The mean weekly dose of DBO was reduced from 34.56 ± 31.12 to 31.11 ± 28.64 μg post-protocol implementation (p = 0.011), which translated to a cost savings of USD 41,649 over 6 months. The mean monthly IV iron dose also decreased from 139.56 ± 98.83 to 97.65 ± 79.05 mg (p < 0.005), a cost savings of USD 18,594 over the same time period. CONCLUSION The use of an anemia management protocol resulted in the deprescribing of DBO and iron agents while increasing the number of patients in the target Hgb range, which led to significant cost savings in the treatment of anemia.

Abstract
Ever since the introduction of EPO, ESAs and iron dosing have been driven by financial incentives. When ESAs were a profit center for providers, large doses were used. With ESAs becoming a cost center, a new trend has appeared, gradually replacing their use with iron to achieve the same therapeutic effect at lower cost. This financially driven approach, treating ESAs and iron as alternatives, is not consistent with human physiology where these agents act in a complementary manner. It is likely that we are still giving unnecessarily large doses of ESAs and iron, relative to what our patients' true needs are. Although we have highlighted the economic drivers of this outcome, many other factors play a role. These include our lack of understanding of the complex interplay of the anemia of chronic disease, inflammation, poor nutrition, blood loss through dialysis, ESAs and iron deficiency. We propose that physiology-driven modeling may provide some insight into the interactions between erythropoiesis and ferrokinetics. This insight can then be used to derive new, physiologically compatible dosing guidelines for ESAs and iron.

Abstract
CHF is a disease of high incidence and prevalence in the elderly. Anemia is associated with an increased mortality in these patients. Erythropoietin secretion is reduced in these patients due to complexed mechanisms. Although some improvement in quality of life has been shown when using ESAs it has not been found any decrement on mortality. Moreover, safety reports suggest an increased risk of thromboembolic event. Together with the high drug cost, the use of ESAs cannot be recommended for the treatment of CHF patients.

Abstract
BACKGROUND Pharmacists successfully manage patients with anemia and chronic kidney disease (CKD), but the cost effectiveness of these programs is unknown. OBJECTIVE To compare the cost effectiveness of pharmacist-managed erythropoiesis-stimulating agent (ESA) clinics with that of usual care in patients with non-dialysis-dependent (NDD)-CKD. METHODS A Markov model was used to estimate the incremental cost effectiveness of pharmacist-managed ESA clinics compared with usual care in outpatient veterans receiving ESAs for NDD-CKD in 2009. The analysis was conducted from a US Veterans Health Administration perspective with a 5-year time horizon, and the year of valuation for cost results was 2012. The effect of parameter uncertainty was explored in one-way and probabilistic sensitivity analyses. RESULTS In the deterministic base case analysis, costs and effectiveness per patient over 5 years were US$13,412 and 2.096 quality-adjusted life-years (QALYs) in the pharmacist-managed ESA clinics and US$16,173 and 2.093 QALYs in usual care; ESA clinics dominated usual care. In one-way sensitivity analyses, ESA clinics no longer dominated if their patients' probability of being in the target hemoglobin range fell to 52 % (base case 71 %) or if the mean cost/patient/month of epoetin or darbepoetin in ESA clinics increased to approximately US$382 (base case US$226) or US$477 (base case US$268), respectively. When all parameters were varied simultaneously in a probabilistic sensitivity analysis, ESA clinics were favored ≥80 % of the time at willingness-to-pay thresholds of US$0-$100,000 per QALY gained. CONCLUSIONS Pharmacist-managed ESA clinics were less costly and more effective than usual care in patients receiving ESAs for anemia and NDD-CKD. Results were robust to variation and support the use of pharmacist-managed ESA clinics.

Abstract
OBJECTIVE To compare the assumptions and estimands across three approaches to estimate the effect of erythropoietin-stimulating agents (ESAs) on mortality. STUDY DESIGN AND SETTING Using data from the Renal Management Information System, we conducted two analyses using a change to bundled payment that, we hypothesized, mimicked random assignment to ESA (pre-post, difference-in-difference, and instrumental variable analyses). A third analysis was based on multiply imputing potential outcomes using propensity scores. RESULTS There were 311,087 recipients of ESAs and 13,095 non-recipients. In the pre-post comparison, we identified no clear relationship between bundled payment (measured by calendar time) and the incidence of death within 6 months (risk difference -1.5%; 95% confidence interval [CI] -7.0%, 4.0%). In the instrumental variable analysis, the risk of mortality was similar among ESA recipients (risk difference -0.9%; 95% CI -2.1, 0.3). In the multiple imputation analysis, we observed a 4.2% (95% CI 3.4%, 4.9%) absolute reduction in mortality risk with the use of ESAs, but closer to the null for patients with baseline hematocrit level >36%. CONCLUSION Methods emanating from different disciplines often rely on different assumptions but can be informative about a similar causal contrast. The implications of these distinct approaches are discussed.

Abstract
BACKGROUND Anaemia is a risk factor for death, adverse cardiovascular outcomes and poor quality of life in patients with chronic kidney disease (CKD). Erythropoietin Stimulating Agents (ESA) are the most used treatment option. In observational studies, higher haemoglobin (Hb) levels (around 11-13 g/dL) are associated with improved survival and quality of life compared to Hb levels around 9-10 g/dL. Randomized studies found that targeting higher Hb levels with ESA causes an increased risk of death, mainly due to adverse cardiovascular outcomes. It is possible that this is mediated by ESA dose rather than haemoglobin concentration, although this hypothesis has never been formally tested. METHODS We present the protocol of the Clinical Evaluation of the Dose of Erythropoietins (C.E. DOSE) trial, which will assess the benefits and harms of a high versus a low ESA dose therapeutic strategy for the management of anaemia of end stage kidney disease (ESKD). This is a randomized, prospective open label blinded end-point (PROBE) design trial due to enroll 900 haemodialysis patients. Patients will be randomized 1:1 to 4000 UI/week i. v. versus 18000 UI/week i. v. of epoetin alfa, beta or any other epoetin in equivalent doses. The primary outcome of the trial is a composite of cardiovascular events. In addition, quality of life and costs of these two strategies will be assessed. The study has been approved and funded by the Italian Agency of Drugs (Agenzia Italiana del Farmaco (AIFA)) within the 2006 funding plan for independent research on drugs (registered at www.clinicaltrials.gov (NCT00827021)).

Abstract
BACKGROUND Historically, the Renal Unit at King's College Hospital used intravenous (IV) iron sucrose (IS) to treat iron deficiency anaemia in patients with chronic kidney disease who were not on dialysis (CKD-ND). As part of a service initiative to improve patient experience, new products were considered as alternatives. This study investigated the potential impact on patient experience and service costs by switching from IS to ferric carboxymaltose (FCM). METHODS A decision analytical model was used to calculate the impact of switching from IS to FCM for a cohort of CKD-ND patients. Service provision data were collected for 365 patients who received 600 mg IS within a 12 month period, creating the IS data set. The service provision data, along with a clinically relevant FCM administration protocol (stipulating total doses of 500 mg FCM), were used to calculate a corresponding theoretical data set for FCM for the same cohort of patients. RESULTS The FCM protocol saved each patient two hospital visits and 2.66 hours of time (equating to approximately a saving of £36.21 in loss of earnings) and £19 in travel costs. Direct attributable costs for iron administration (which included drug, disposables, nursing staff, and hospital-provided patient transport costs) were £58,646 for IS vs £46,473 for FCM. Direct overhead costs (which included nursing preparation time, administration staff, clinic space, and consultant time costs) were £40,172 for the IS service vs £15,174 for the FCM service. LIMITATIONS Based on clinical experience with the products, this analysis assumes that 500 mg FCM is therapeutically equivalent to 600 mg IS. Consultant time costs are assumed to be the same between the two treatment groups. IV iron administration protocols and data are specific to King's College Hospital. The design is retrospective and changes to the management of the clinic, including service delivery optimization, may also affect real costs. CONCLUSION FCM was associated with fewer hospital visits and reduced transport costs for CKD-ND patients receiving IV iron and has the potential to save 19-37% in service costs. Owing to increased administration efficiency, FCM can improve the overall patient experience while reducing the total cost of the King's College Hospital IV iron service for CKD-ND patients, compared with treatment with IS.

Abstract
PURPOSE Erythropoiesis-stimulating agents can reduce red blood cell transfusion rates in patients developing anemia while receiving chemotherapy. We investigated potential cost savings from reduced transfusion rates in patients starting darbepoetin alfa (DA) at higher versus lower hemoglobin (Hb) levels. METHODS Two systematic literature reviews were performed: transfusion outcomes in patients receiving DA stratified by baseline Hb level and costs of transfusion in Europe. Potential cost savings were calculated by multiplying the difference in transfusion rates between Hb levels by the midpoint of transfusion costs. RESULTS Despite differences in baseline characteristics, treatment duration and analysis technique, the clinical studies (n = 8) showed that fewer transfusions were required when DA was initiated at higher versus lower Hb levels. The economic studies (n = 9) showed that 1 unit of transfusion ranged from <euro>130 to <euro>537 (2010-adjusted values). Cost savings from initiating DA at higher versus lower Hb levels were <euro>503-2,226 (2 units transfused) and <euro>880-3,895 (3.5 units) per ten patients. CONCLUSIONS Transfusion incidence increases with DA initiation at lower Hb levels. Potential cost savings depend on the number of units transfused and cost items included. DA initiation according to guidelines can reduce transfusions and potentially reduce transfusion-associated costs.

Abstract
The four currently available erythropoiesis-stimulating agents (ESAs), the main drugs for correcting anemia in patients with chronic kidney disease (CKD), are epoetin alfa, epoetin beta, darbepoetin alfa, and continuous erythropoietin receptor activator. The last two have much longer half-lives, which means they can be administered less frequently. The expiry of the patents for epoetin alfa and epoetin beta some years ago opened up the way for the production of a number of biosimilars that are now marketed in the European Union. Because biosimilars cannot be identical to their originator, a complex and still-evolving regulatory policy has been generated, but there are still a number of issues concerning international naming, automatic substitution, and safety. All ESAs are effective in correcting renal anemia and increasing hemoglobin levels, but the choice of which to use should also take into account their pharmacokinetics and pharmacodynamics, their administration route, and economic issues. Following the publication of a number of trials indicating no benefit (and even possible harm) when ESAs are used to aim at near-normal hemoglobin levels in CKD patients, the hemoglobin target has become a major subject of discussion. According to the position statement of the Anemia Group of the European Renal Best Practice, it should generally be about 11-12 g/dL; however, a risk-benefit evaluation is warranted in individual patients, and high ESA doses driven by hyporesponsiveness should be avoided.

Abstract
OBJECTIVE To compare utilization and associated costs of epoetin alfa (EPO) and darbepoetin alfa (DARB), two erythropoiesis-stimulating agents (ESAs), in patients with cancer undergoing chemotherapy and patients with chronic kidney disease (CKD) not on dialysis in inpatient and outpatient hospital settings. METHODS An analysis of medical claims recorded between January 2006 and December 2009 was conducted using the Premier Perspective Comparative Hospital database. Patients included were ≥18 years old with cancer and chemotherapy or with pre-dialysis CKD and with ≥1 claim for EPO or DARB during a hospital inpatient or outpatient treatment episode. Patients treated with both ESAs or who were receiving dialysis were excluded. Mean cumulative drug costs and dose ratios (units EPO: mcg DARB) were calculated using cumulative dose and April 2010 wholesale acquisition costs. RESULTS Cancer chemotherapy: 13,832 inpatient stays (EPO: 10,454; DARB: 3378) and 5590 outpatient treatment episodes (EPO: 2856; DARB: 2734) were identified. The inpatient and outpatient populations reported ESA dose ratios of 230:1 and 238:1 with DARB cost premiums of 42% (EPO: $948; DARB: $1348) and 38% (EPO: $3358; DARB: $4627), respectively. CKD: 148,746 hospital stays (EPO: 116,017; DARB: 32,729) and 11,012 outpatient treatment episodes (EPO: 6921; DARB 4091) were identified. The inpatient and outpatient populations reported ESA dose ratios of 251:1 and 257:1 with DARB cost premiums of 30% (EPO: $566; DARB: $738) and 27% (EPO: $2077; DARB: $2642), respectively. LIMITATIONS The lack of randomization may have led to confounding by indication. In addition, statistical significance must be interpreted with caution in studies involving large samples. CONCLUSIONS This study of 19,422 patients with cancer receiving chemotherapy and 159,758 patients with pre-dialysis CKD reported ESA dose ratios ranging from 230:1-257:1 (units EPO: mcg DARB) and associated cost premiums of 27-42% for DARB.

Abstract
OBJECTIVE To evaluate the economic impact of intravenous iron (in the form of intravenous iron preparation of ferric carboxymaltose) in three different clinical settings of iron deficiency anemia: chemotherapy-induced anemia in breast cancer, chemotherapy-induced anemia in digestive cancer, and perioperative anemia in knee and hip surgery. METHODS The economic model compared the usual therapeutic strategies of anemia without intravenous iron and strategies including intravenous iron, in each of the three clinical settings selected. Costs related to anemia treatment by erythropoiesis-stimulating agents (ESA), blood transfusion, and intravenous iron were estimated and compared inside each setting. Cost savings were calculated from the French healthcare payer perspective. Data included in the economic model were obtained from scientific literature, public health agencies, and medical experts. RESULTS The most prominent annual cost savings were observed in chemotherapy-induced anemia in breast cancer (€997 and €360 per patient for metastatic and non-metastatic breast cancers, respectively; global cost saving, €33.6 million). This large impact of intravenous iron on costs was mainly explained by both a lower number of women treated and lower ESA dosing. Mean annual cost saving in digestive cancers and knee and hip surgery were estimated to €168 and €216 per patient and global cost savings of €7.5 and €12.1 million, respectively. Overall, annual cost savings in these three settings were estimated to €53 million including €39 million for ESA cost savings. Sensitivity analysis showed that strategies including intravenous iron remained cost-effective even with wide variations in the assumptions, particularly for cost savings on ESA. LIMITATIONS Economic model based on literature data and expert opinions. CONCLUSIONS The present economic model suggests that use of intravenous iron, according to recommendations of international guidelines, is cost saving, particularly in chemotherapy-induced anemia in breast cancers.

Abstract
OBJECTIVE Cost-analysis comparing darbepoetin-alfa (DARB), epoetin-alfa (EPO-A), and epoetin-beta (EPO-B) for treatment of chemotherapy-induced anemia in Belgium concluded that costs for DARB-treated patients were significantly lower than costs for EPO-A- or EPO-B-treated patients. The objective of the present study was to extend the Belgian analysis to Austria, France, Italy, Portugal, and Spain, estimating differences in costs between erythropoiesis-stimulating agents (ESAs) in each country. METHODS Differences in epidemiology and treatment patterns between countries were adjusted using data from Eurostat, national cancer registries, IMS sales data, and reimbursement and treatment guidelines. Belgian unit costs were replaced with country-specific costs. Costs were analyzed using a mixed-effects model stratifying for propensity score quintiles. RESULTS All populations were comparable to the Belgian population in terms of age, gender, ESA, and blood transfusions use. After adjusting for country-specific chemotherapy use and cancer incidence, total management costs per patient (Euro, 2010) were 19-26% (France, Spain) lower with DARB compared with EPO-A (p < 0.0001) and 20-36% (Portugal, Austria) compared with EPO-B (p < 0.01). Anemia-related costs with DARB were between 12% (Portugal; p = 0.0235) and 38% (Italy; p < 0.0001) lower compared with EPO-A (p < 0.01; all remaining countries), and between 13% (Austria; p = 0.064) and 19% (Portugal; p = 0.0028) lower compared with EPO-B (p < 0.05; all remaining countries except Italy; p = 0.0935). LIMITATIONS Not all differences could be accounted for by a lack of country-specific data; however, the potential under- and over-estimation of costs should be similar for all three ESAs. CONCLUSIONS These findings are in line with the Belgian analysis. In all countries, total and anemia-related costs were lowest in patients receiving DARB vs EPO-A or EPO-B. This study demonstrates the feasibility of adapting real-life country-specific data to other settings, adjusting for differences in patients' characteristics and treatment strategies. These findings should be valuable in healthcare decision-making in oncology patients treated in each of the countries studied.

Abstract
BACKGROUND Regulatory requirements for the pharmaceutical industry have become increasingly demanding with respect to the safety and effectiveness of drugs. OBJECTIVE The objective of this study was to determine the willingness to pay (WTP), of both the Dutch general public and dialysis patients, for regulatory requirements related to reducing the risk of pure red cell aplasia (PRCA) associated with epoetin alpha use. METHODS A survey was carried out in April 2009. The Dutch general public (n = 422) was approached through a survey sampling agency. Patients (n = 112) were included through several Dutch dialysis clinics because they are often treated with epoetin alpha and therefore were expected to have a higher WTP than the general public. The survey aimed to determine the WTP for reducing the risk of PRCA in epoetin alpha users from 4.5 to 0 per 10 000 patients per year, based on regulatory actions that have been taken by the European Medicines Agency (EMA). WTP was determined via a payment scale and an open-ended follow-up question. Patients were asked how much extra per year they would be willing to pay for their basic healthcare insurance. We used two censored regression models to test the association between WTP and a set of independent variables: a Tobit model with the stated WTP as the dependent variable and an interval regression model with the interval between the lower and upper bounds of the payment scale as the dependent variable. RESULTS The patients' mean WTP was significantly higher (€46.52) than that of the general public (€24.40). The Tobit model showed significant associations (α = 0.05) with WTP for dialysis patients, risk perception and respondents' opinions on costs of healthcare. The interval regression model showed significant associations with WTP for the same variables as the Tobit model and for one additional variable (risk aversion). Income did not significantly affect WTP. A scenario with a 10-fold larger risk reduction did not increase WTP significantly. CONCLUSION This study is, as far as we know, one of the first attempts to analyse the WTP for drug regulation and should in future be used in studies of the societal costs of drug regulation for epoetin alpha use. Our results indicate that the Dutch general public, especially Dutch dialysis patients, are willing to pay limited amounts to reduce the risk of serious adverse events associated with drug use.

Abstract
STATEMENTS OF THE PROBLEM Correction of anemia in type 2 diabetes (T2DM) patients with chronic kidney disease stages 3-4 may slow the decline of kidney function but may increase cardiovascular risk through higher hematocrit. The NEPHRODIAB2 study was designed to assess efficacy and safety of complete hemoglobin (Hb) normalization in these patients. METHODS We randomly assigned 89 T2DM patients with an estimated glomerular filtration rate (eGFR; abbreviated 175 Modification of Diet in Renal Disease formula) of 25 to 60 ml/min per 1.73 m(2) and moderate anemia (Hb, 100-129 g/l) to a target Hb value in subnormal range (110-129g/l, group 1, n=43) or normal range (130-149 g/l, group 2, n=46). The primary end point was eGFR decline after 2 years of follow-up. Secondary end points included iron and erythropoietin dosage, quality of life (Medical Outcomes Study 36-item Short-Form Health Survey scores) and adverse events. RESULTS Six months after randomization, the mean Hb levels were <120 g/l in group 1 and >130 g/l in group 2 (P<.05 at 6, 12, 18 and 24 months). Blood pressure, 24-h proteinuria and HbA1c did not differ during follow-up (P>.05). Two-year declines in eGFR were -8.7±12.2 in group 1 and -5.1±7.8 ml/min per 1.73 m(2) in group 2 (P=.29). Mean weekly use of erythropoietin was 7.8±11.6 μg in group 1 and 30.1±33.6 μg in group 2 (P<.0001). There was no significant difference regarding Medical Outcomes Study 36-item Short-Form Health Survey score change or adverse event occurrence. CONCLUSIONS In this trial, normalization of Hb level in T2DM patients with chronic kidney disease was safe but did not significantly slow renal function decline and increased treatment cost due to erythropoietin use.

Abstract
Purpose To assess the clinical and economic outcomes among patients with chemotherapy-induced anemia (CIA) treated with United States Food and Drug Administration-approved fixed dosing regimens of erythropoiesis-stimulating agents (ESA). Methods Data were employed from the Dosing and Outcomes Study of Erythropoiesis-Stimulating Therapies (DOSE) registry to evaluate CIA patients who were initiated on either epoetin alfa (EPO) 40,000 Units (U) or darbepoetin alfa (DARB) 500 micrograms (mcg) between January 1, 2006 and May 8, 2009. Study measurements included ESA treatment dose and dose ratio, changes in hemoglobin (Hb) levels from baseline, and cumulative ESA costs. Results Five hundred forty patients treated in 44 clinical centers were evaluated, of which 420 were initiated on EPO 40,000 U and 120 were initiated on DARB 500 mcg. Both cohorts had similar baseline characteristics, although EPO patients were less likely than DARB patients to have received iron supplementation before ESA initiation (11.4% EPO vs. 20.0% DARB, p = 0.015). The EPO-to-DARB dose ratio based on cumulative ESA dose was 169:1 (U EPO: mcg DARB). EPO patients showed statistically greater Hb improvement compared to DARB patients, and compared to EPO patients, a greater proportion of DARB patients required a blood transfusion (13.9% EPO vs. 22.5% DARB, p = 0.026). Mean cumulative ESA cost was significantly lower for EPO patients than DARB patients ($4,261 EPO vs. $8,643 DARB, p < 0.0001). Conclusions These findings reported that patients with CIA achieved more favorable clinical and economic outcomes if initiated with EPO 40,000 U vs. DARB 500 mcg.

Abstract
Cancer patients frequently develop chemotherapy-induced anemia, which can be treated with erythropoiesis-stimulating agents. These agents have shifted the standard of chemotherapy-induced anemia treatment away from the previous mainstay of red blood cell transfusions. In July 2007, the Centers for Medicare and Medicaid Services issued a National Coverage Decision restricting reimbursement for erythropoiesis-stimulating agents to those chemotherapy patients who have hemoglobin levels <10 g/dL at initiation of therapy. This decision was hypothesized to place a greater reliance on transfusions for chemotherapy-induced anemia treatment. This observational study examined transfusions and erythropoiesis-stimulating agent utilization rates within defined episodes of chemotherapy care using electronic medical records from seven practices consisting of 39 sites of care across seven states. We compared the frequency of myelosuppressive chemotherapy treatment, erythropoiesis-stimulating agent administrations, and red blood cell transfusions before and after the National Coverage Decision in oncology patients with chemotherapy-induced anemia. Although exposure to myelosuppressive chemotherapy was not different, erythropoiesis-stimulating agent administrations significantly decreased and blood transfusions significantly increased after implementation of the National Coverage Decision. The 31% increase in transfusions for patients aged 65 years and older was significant (P = 0.007) and higher than the 8% increase for patients younger than 65 years (P = 0.358). Changes in practice patterns for chemotherapy-induced anemia treatment that followed the Centers for Medicare and Medicaid Services reimbursement decision for erythropoiesis-stimulating agents seem to be impacting practice patterns. Further research is necessary to determine whether these changes represent a widespread and durable shift in patient treatment.

Abstract
For those affected by anemia, receiving the proper treatment can improve quality of life. The most common treatment is erythropoiesis-stimulating agents (ESAs), which can provide significant improvements in health-related quality of life for those who have anemia and comorbidities of either cancer, human immunodeficiency virus/acquired immunodeficiency syndrome, or chronic kidney disease. But the guidelines associated with ESAs can cause confusion for those tasked with prescribing them, so it is imperative that clinicians be more cognizant of the treatment recommendations for different patient populations to make the proper treatment decisions. With the multiple safety issues involved in administering ESAs, our institution prefers to err on the side of caution until these concerns are resolved.

Abstract
In conclusion, the most important priority is to shift thinking to ESA dose exposure and away from focusing on the target Hb level. More attention needs to be spent on developing strategies to minimize exposure to high doses of ESAs. Possible strategies might include the subcutaneous administration of ESAs, treating a patient with an elevated ferritin, identifying sources of blood losses, treating infections and/or an inflammatory focus, and the use of computerized protocols. An equally important goal should be to change the CMS QIP anemia measure to a target Hb >9 g/dL. This modification in the QIP anemia measure is supported by the evidence from both the Normal Hematocrit trials and TREAT. If one models the effect of this QIP on the dialysis patient population as a whole, the majority of achieved Hb concentrations will likely be <11 g/dL (similar to the reported findings in the Normal Hematocrit study--see Figure 1). Lastly, translational studies and clinical trials are necessary to test whether exposure to high doses of ESAs explains the higher risk observed in CHOIR, TREAT, and the Normal Hematocrit study.

Abstract
New Medicare rules that set forth a revised reimbursement scheme for dialysis services will introduce significant changes for providers. The new rules will abandon the current system of separate reimbursement for drugs associated with the hemodialysis services, including erythropoiesis-stimulating agents (ESAs) and intravenous (i.v.) iron. These rules will "bundle" these agents and related laboratory tests into a single, case-mix adjusted composite rate. These bundling rules will be gradually phased-in, beginning in 2011. One of the primary effects of the new reimbursement policy will be to discourage over-utilization of ESAs that comprise nearly one-quarter of hemodialysis-related Medicare expenditures. As a result, hemodialysis providers will be challenged to make hemodialysis services more cost-effective, while ensuring that Medicare clinical performance measures are met and patient care is not compromised. i.v. iron has an integral role in making anemia care more cost-effective in the hemodialysis setting by improving measures of iron-deficiency anemia, maintaining necessary iron balance, and reducing the utilization of ESAs. This review discusses the potential benefits of i.v. iron in the management of hemodialysis patients with iron-deficiency anemia. It also focuses on the available i.v. iron options, particularly the established efficacy and safety profile of i.v. iron dextran compared with other i.v. iron formulations as well as cost considerations.

Abstract
OBJECTIVE To assess the health-related quality of life (HRQL) and economic burden of chronic kidney disease (CKD) related anemia in non-dialysis patients in the United States (US) via literature review. METHODS MEDLINE, EMBASE, PROQOLID, and Cochrane Library/Renal Group Resources were searched. Studies were appraised for patient populations, disease-specific versus generic HRQL assessments, and type and magnitude of health-related costs. RESULTS The treatment costs for CKD patients with anemia compared to those without anemia were significantly higher and were blunted but persistent after controlling for comorbidities and confounders. Intervention with erythropoiesis stimulating agents (ESA) decreased anemia and avoided hospital admissions. Costs were higher when anemia was poorly controlled or untreated. HRQL burden was mainly due to physical limitations and difficulty in ability to perform activities of daily living. Significant positive correlations between increases in hemoglobin levels and HRQL measures were reported. CONCLUSIONS Although evidence is limited, the economic and HRQL burden of non-dialysis CKD-related anemia is substantial. Under-treatment of anemia may contribute to higher resource consumption and higher costs; however, patient co-morbidities, use of erythropoietin-stimulating agents, and overall management introduce potential confounds. The contribution of anemia to humanistic disease burden is due to a constellation of factors, including physical activity and functional status.
