Limited evidence suggests chronic graft-versus-host disease (cGvHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) increases healthcare resource utilization (HCRU) and costs. However, this burden has not been well characterized in England. This study assesses secondary care HCRU and costs for patients following allo HSCT in England with cGvHD and patients who did not develop graft-versus-host disease (GvHD). Further stratification was performed among patients who did or did not subsequently receive high-cost therapies for the treatment of cGvHD. This descriptive, retrospective cohort study used Hospital Episode Statistics (HES) data from April 2017 to March 2022. HES data captures information on reimbursed diagnoses and procedures from all National Health Service (NHS) secondary care admissions and attendances in England. High-cost drugs as defined by NHS England are recorded in HES, these drugs and other procedures including plasma exchange, were used to identify patients with cGvHD who were in receipt of high-cost therapies. HCRU and costs were described for patients with cGvHD following allo-HSCT (n = 721) and were matched with patients with no evidence of GvHD following allo-HSCT (n = 718). HCRU and costs were also described for the subset of patients with cGvHD (n = 198) following receipt of high-cost therapies and patients with cGvHD prior to or without such therapies (n = 523). A higher proportion of patients with cGvHD had at least one inpatient or intensive care unit (ICU) admission or emergency care attendance than patients without GvHD (inpatient: 74.6% versus 66.6%; emergency care: 39.3% versus 30.5%; ICU: 7.4% versus 4.7%; respectively); whilst the proportion of patients with an outpatient attendance were similar for both groups (outpatient: 80.3% versus 84.1%; respectively). The cost across all secondary care settings was higher for patients with cGvHD than patients without GvHD, with a mean cost of inpatient admissions of £17,339 per patient-year for those with cGvHD versus £8548 per patient-year in patients without GvHD. A higher proportion of patients who received high-cost therapies for the treatment of cGvHD had at least one secondary care admission or attendance, than patients who did not (inpatient: 85.4% versus 66.4%; ICU: 7.1% versus 5.4%; outpatient: 87.9% versus 76.7%; emergency care: 44.4% versus 36.5%; respectively). Patients who were treated with high-cost therapies for the treatment of cGvHD had a greater mean number (14.6 versus 8.2 per patient-year, respectively) for all-cause inpatient admissions after treatment than patients who did not. In all secondary care settings, the total cost per patient-year was higher for patients who received high-cost therapies for the treatment of cGvHD, than for those who did not. Patients who were treated with high-cost therapies for the treatment of cGvHD had a greater mean cost (£21,137 versus £15,956 per patient-year, respectively) for all-cause inpatient admissions than patients who did not. This study demonstrates that cGvHD and the use of associated high-cost therapies impacts healthcare activity and costs across various secondary care settings in England more than patients without GvHD and patients with cGvHD who received no high-cost therapies., (Copyright © 2024 The American Society for Transplantation and Cellular Therapy.

Background: Cytomegalovirus infection (CMV) is a common complication after allogeneic hematopoietic stem cell transplantation (AHSCT). CMV infection increases transplantation costs; however, the extent of the financial burden may vary in different countries. This study aims to determine the clinical and economic impact of CMV infection in patients undergoing AHSCT in a middle-income country., Methods: A total of 150 adult and pediatric patients post-AHSCT were included for analysis. In addition to incidence of CMV infections, data on graft versus host disease (GVHD) were also collected. Standard hospital charges for AHSCT and any additional transplantation-related expenditure within 12 months were also retrieved in 104 patients., Results: CMV infection, acute GVHD and chronic GVHD occurred in 38.7%, 60.7%, and 22.0% of patients, respectively. Patients with CMV infections had higher readmission rates compared to those who did not (67.2% vs. 47.8%; p = 0.020). Additional expenditure was seen in HLA-haploidentical AHSCT and CMV infection (MYR11 712.25/USD2 504.49; p < 0.0001 and MYR5 807.24/USD1 241.79; p = 0.036), respectively., Conclusion: This single-center study demonstrated that patients who underwent HLA-haploidentical AHSCT and subsequently developed CMV infection had higher transplantation expenditures compared to those who had matched-related transplantation. Further studies should be conducted to evaluate if primary prophylaxis against CMV is cost-effective, especially in patients who undergo HLA-haploidentical AHSCT., (© 2024 John Wiley & Sons A/S.

Allogeneic hematopoietic cell transplantation (allo-HCT) has the potential for curative outcomes for a variety of hematologic malignancies. Current allo-HCT studies often describe the outcomes and costs in the near term; however, research on the lifetime economic burden post-allo-HCT remains limited. This study was conducted to estimate the average total lifetime direct medical costs of an allo-HCT patient and the potential net monetary savings from an alternative treatment associated with improved graft-versus-host disease (GVHD)-free, relapse-free survival (GRFS). A disease-state model was constructed using a short-term decision tree and a long-term semi-Markov partitioned survival model to estimate the average per-patient lifetime cost and expected quality-adjusted life years (QALYs) for an allo-HCT patient from a US healthcare system perspective. Key clinical inputs included overall survival, GRFS, incidence of both acute and chronic GVHD, relapse of the primary disease, and infections. Cost results were reported as ranges based on varying the percentage of chronic GVHD patients that remained on treatment after 2 years (15% or 39%). Over a lifetime, the average per-patient medical cost of allo-HCT was estimated to range from $942,373 to $1,247,917. The majority of the costs were for chronic GVHD treatment (37% to 53%), followed by the allo-HCT procedure (15% to 19%). The expected lifetime QALYs of an allo-HCT patient were estimated as 4.7. Lifetime per-patient treatment costs often exceed $1,000,000 for allo-HCT patients. Innovative research efforts focused on the reduction or elimination of late complications, particularly chronic GVHD, may provide the greatest value to improved patient outcomes., (Copyright © 2023 The American Society for Transplantation and Cellular Therapy.

This study aims to evaluate the efficacy, safety, and long-term cost-effectiveness of fixed-dose busulfan (Bu) administration and pharmacokinetically (PK) guided adjustment of Bu dose for patients who underwent hematopoietic stem cell transplantation. The efficacy and safety of both dosing strategies were compared using a systematic review and meta-analysis. A Markov model was used in estimating relevant cost and health outcomes from the perspective of the health system. The primary outcomes of interest were lifetime cost, quality adjusted life-years (QALYs) gained, and incremental cost-effectiveness ratio (ICER) in dollar per QALY gained. Results showed that progression-free survival and overall survival in the PK-guided group were higher than that in the fixed-dose group, and the PK-guided group was associated with low non-relapse mortality and relapse rate. In contrast to safety, the incidence of acute graft-versus-host disease (GVHD) was the same in the two groups (P > 0.05). Cost-effectiveness analysis showed that the QALY of the PK-guided group (12.8135 QALYs and $582,475.07) increased by 2.0609 relative to that in the fixed-dose group (10.7526 QALYs and $562,833.20), and the ICER was $9530.72/QALY. One-way and probability sensitivity analyses confirmed the reliability of the results. In conclusion, the PK-guided approach has higher efficacy and is safer., (© 2021.

Background: This study assessed pharmacoeconomic costs associated with extracorporeal photopheresis (ECP) compared with other available second-line therapies for chronic graft-vs-host disease (cGvHD) in a tertiary Spanish institution., Methods: Patients (≥18 years) diagnosed with steroid-refractory cGvHD were eligible. Data were collected retrospectively from index date until 1 year or relapse. Patients were distributed in two cohorts (ECP vs non-ECP), matched by age (≤ or > 40), hematopoietic stem cell transplant (HLA-identical sibling donor or other) and number of previous immunosuppressive lines (1, 2, or ≥ 3). Costs were assigned using the 2016 diagnosis-related group (DRG) system: DRG 579 (€22 383) overnight stay due to major complication (ie, sepsis, pneumonia, parenteral nutrition, or respiratory failure), and DRG 875 (€5154) if no major complication. The primary endpoint was healthcare resource utilization per patient., Results: Forty patients (n = 20 per cohort) were included. Median age was 49, and 37.5% were female. Mean total cost per patient was €25 319 (95% CI: €17 049-€33 590) across the two cohorts, with a slightly lower mean cost per ECP-treated patient (€23 120) compared with the non-ECP cohort (€27 519; P = .597). Twenty-seven inpatient hospitalizations occurred among ECP-treated patients, vs 33 in the non-ECP cohort. Day hospital and external consultations were more frequent in the ECP cohort. However, fewer inpatient admissions included DRG 579 compared with the non-ECP cohort (44% vs 58%). Inpatient length of stay was slightly shorter in the ECP cohort (30 vs 49 days; P = .298)., Conclusions: ECP treatment may yield economic savings in Spain through resource savings and moving costs toward outpatient care., (© 2021 Hospital Universitari i Politechnic La Fe.

Aim: To compare secondary systemic treatment (SST) continuation and associated resource use and costs in chronic graft-versus-host disease (cGvHD) patients in the USA.  Materials & methods : This was a retrospective study using Truven Health MarketScan database (2009-2016). cGvHD patients were classified as continuers or discontinuers if treated with SST for ≥180 days without or with a treatment gap (≥45 days), respectively. Results: Among 464 cGvHD patients with SST, mTOR inhibitors, extracorporeal photopheresis and imatinib were most frequently used. A total of 172 patients were SST continuers and 292 were discontinuers. Extracorporeal photopheresis treated patients were the highest continuers, followed by imatinib and mTOR inhibitors. SST continuers had lower monthly hospitalization costs versus discontinuers. Conclusion: This real-world analysis demonstrates high SST continuation rates in cGvHD patients are associated with lower resource utilization and cost.

Purpose: The contribution of acute graft-versus-host disease (GVHD) to healthcare resource utilization (HCRU) and costs following allogeneic hematopoietic cell transplantation (HCT) has not been extensively investigated. The objective of this study was to estimate both inpatient and outpatient HCRU and costs associated with acute GVHD during the 100-day and 1-year periods after allogeneic HCT in the USA., Methods: A retrospective analysis of administrative claims from the Optum® Research Database of patients aged ≥ 12 years who received HCT between 2010 and 2016 was conducted. Costs and HCRU among patients with acute GVHD and no GVHD were compared during the 100-day (acute GVHD, n = 723; no GVHD, n = 385) and 360-day (acute GVHD, n = 445; no GVHD, n = 227) periods after HCT., Results: Patients with acute GVHD had significantly more (P < 0.001) mean office visits (47 vs 32), hospital outpatient visits (71 vs 35), and inpatient stays (2.8 vs 1.1) than patients with no GVHD during 360 days post-HCT; similar findings were observed over the 100-day period. Mean total all-cause costs were significantly higher (P < 0.001) for patients with acute GVHD versus no GVHD during both post-HCT periods (100-day, $316,458 vs $215,229; 360-day, $466,720 vs $263,568). Additional factors associated with increased 360-day costs included young age (12-17 years; P < 0.001) and peripheral blood as graft source (P = 0.03)., Conclusion: Acute GVHD was associated with significant HCRU and costs in the first 100 days of transplant, increasing over the first year post-HCT. Inpatient care was the primary driver, but outpatient care and related costs were also increased.

Understanding the socioeconomic impact of chronic graft-versus-host disease (GVHD) on affected patients is essential to help improve their overall well-being. Using data from the Chronic GVHD Consortium, we describe the insurance, employment, and financial challenges faced by these patients and the factors associated with the ability to work/attend school and associated financial burdens. A 15-item cross-sectional questionnaire designed to measure financial concerns, income, employment, and insurance was completed by 190 patients (response rate, 68%; 10 centers) enrolled on a multicenter Chronic GVHD Consortium Response Measures Validation Study. Multivariable logistic regression models examined the factors associated with financial burden and ability to work/attend school. The median age of respondents was 56years, and 87% of the patients were white. A higher proportion of nonrespondents had lower income before hematopoietic cell transplantation and less than a college degree. All but 1 patient had insurance, 34% had faced delayed/denied insurance coverage for chronic GVHD treatments, and 66% reported a financial burden. Patients with a financial burden had greater depression/anxiety and difficulty sleeping. Nonwhite race, lower mental functioning, and lower activity score were associated with a greater likelihood of financial burden. Younger age, early risk disease, and higher mental functioning were associated with a greater likelihood of being able to work/attend school. In this multicenter cohort of patients with chronic GVHD, significant negative effects on finances were observed even with health insurance coverage. Future research should investigate potential interventions to provide optimal and affordable care to at-risk patients and prevent long-term adverse financial outcomes in this vulnerable group., (Copyright © 2018 American Society for Blood and Marrow Transplantation.

Hematopoietic stem cell transplantation (HCT) is a curative treatment for patients with myelofibrosis (MF); however, many HCT-eligible patients decline this potentially life-saving procedure. The reasons behind this decision are not clear. We sought to survey patients with MF to understand their perspective on HCT. A 63-question survey was posted on myeloproliferative neoplasm patient advocacy websites. A total of 129 patients with MF responded to the survey. Among these patients, 49 (41%) were referred for HCT, and 41(32%) attended the transplantation consult. Of the patients who attended the transplantation consult, 24 (59%) did not plan on going on to HCT, and 16 (41%) intended to proceed with HCT. Reasons for the decision to not undergo transplantation included the desire to not be ill, desire to not spend time in the hospital, and concerns about overall quality of life. Specifically, concerns related to financial impact and the risk of graft-versus-host disease (GVHD) were expressed. Patients who decided to proceed with HCT felt that this would extend their survival and allow them to be around family for longer. This is the first survey to investigate patient perceptions regarding HCT for MF. Less than one-half of the patients were referred for HCT, and of those, less than one-half planned on proceeding with the transplantation, suggesting that many patients do not receive this life-saving procedure. Further exploration of the basis of patients' reluctance to proceed with HCT is warranted., (Copyright © 2018. Published by Elsevier Inc.)

Given the increasing incidence of chronic graft-versus-host disease (cGVHD) and its rapidly escalating costs due to many lines of drug treatments, we aimed to perform a meta-analysis to assess the comparative effectiveness of various treatment options. Using these results, we then conducted a cost-effectiveness analysis for the frequently utilized agents in steroid-refractory cGVHD. We searched for studies examining tacrolimus, sirolimus, rituximab, ruxolitinib, hydroxychloroquine, imatinib, bortezomib, ibrutinib, extracorporeal photopheresis, pomalidomide, and methotrexate. Studies with a median follow-up period shorter than 6 months and enrolling fewer than 5 patients were excluded. Meta-analysis for overall and organ system-specific GVHD response (overall response [ORR], complete response [CR], and partial response [PR]) was conducted for each intervention. Cost per CR and cost per CR + PR were calculated as the quotient of the 6-month direct treatment cost by CR and CR + PR. Forty-one studies involving 1047 patients were included. CR rates ranged from 7% to 30% with rituximab and methotrexate, respectively, and ORR ranged from 30% to 85% with tacrolimus and ruxolitinib, respectively. Cost per CR ranged from US$1,187,657 with ruxolitinib to US$680 with methotrexate. Cost per ORR ranged from US$453 for methotrexate to US$242,236 for ibrutinib. The most cost-effective strategy was methotrexate for all of the organ systems. Pomalidomide was found to be the least cost-effective treatment for eye, gastrointestinal, fascia/joint, skin, and oral GVHD, and imatinib was found to be the least cost-effective treatment for liver and extracorporeal photopheresis for lung GVHD. We observed huge cost-effectiveness differences among available agents. Attention to economic issues when treating cGVHD is important to recommend how treatments should be sequenced, knowing that many patients will cycle through available agents., (Copyright © 2018 The American Society for Blood and Marrow Transplantation.

Chronic graft-versus-host disease (cGVHD) frequently affects the oral mucosa and is generally responsive to topical immunomodulatory therapies. Clinicians may benefit from guidance in choosing the most appropriate therapy with respect to practicality and cost. To assess the economic considerations related to topical immunomodulatory treatments for management of oral mucosal cGVHD and their practical implications. Topical treatments used for management of oral cGVHD were obtained from the National Institutes of Health Consensus document for ancillary and supportive care. Cost data for a standard 1-month prescription was obtained from national databases for commercially available formulations and from compounding pharmacies for formulations requiring compounding. There are numerous topical preparations used for the management of oral cGVHD, many of which require compounding. The average wholesale price of the commercially available agents ranges from $5 to $277/month, and the cost of the compounded preparations ranges from $43 to $499/month. Costs can be influenced by drug-, patient-, and pharmacy-related factors. The costs associated with topical treatment of oral cGVHD are substantial, particularly because the disease is chronic and expenses accumulate over time. Rational prescribing according to a proposed algorithm, including de-escalation of therapy when indicated, can help to minimize associated costs. This has practical implications for patients, physicians, pharmacies, and insurance providers., (Copyright © 2018 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

Costs of HSCT in the United States have been widely reported, but complete information on costs in developing countries is lacking. We performed an analysis designed to assess the real, detailed costs of HSCT in Mexico. Using the database of the Current Accounts Department at our Institution, we performed a micro-costing based analysis of patients from 2010 through 2015 to obtain the overall cost of HSCT during the in-patient procedure and 2-month follow-up. One hundred five transplantations (57% autologous) were performed. The most frequent indications for transplantation were lymphomas (32%), followed by acute leukemias (22%). The most frequently used conditioning regimen was reduced BUCY 2 (38%), followed by BEAM (28%). Among post-transplant complications, acute graft-versus-host-disease was not associated with higher costs (p = 0.8). The median costs (in-patient and 2-month outpatient follow-up) for auto and allo-HSCT were 12,155 and 18,260 USD, respectively. Advances in HSCT technology have improved outcomes and increased the availability of this technique; however, this procedure can also significantly influence the socioeconomic wellbeing of patients, especially in developing countries. Our study highlights the feasibility of performing HSCT in Mexico at lower costs than developed countries, while preserving quality of care.

Objectives: To develop a comparative, cost-effectiveness, and budget impact analysis of Therakos online extracorporeal photopheresis (ECP) compared with the main alternatives used for the treatment of steroid-refractory/resistant chronic graft-versus-host disease (cGvHD) in Italy., Methods: The current therapeutic pathway was identified by searching medical databases and from the results of a survey of practice in Italian clinical reference centers. A systematic review was performed to evaluate the efficacy and safety of second-line alternatives. Budget impact and cost-effectiveness analyses were performed from the Italian National Health Service perspective over a 7-year time horizon through the adaption of a Markov model. The following health states were considered: complete and partial response, stable disease, and progression. A discount rate of 3% was applied to costs and outcomes., Results: The most common alternatives used in Italy for the management of steroid-refractory/resistant cGvHD were ECP, mycophenolate, pentostatin, and imatinib. The literature review highlighted that complete and partial responses are higher with ECP than with the alternatives while serious adverse events are less common. The economic analysis showed that Therakos online ECP represents the dominating alternative, in that it delivers greater benefit at a lower cost. In fact, according to the alternatives considered, cost saving ranged from €3237.09 to €19,903.51 per patient with 0.04 to 0.21 quality-adjusted life-year gained., Conclusions: Therakos online ECP should be considered an effective, safe, and cost-effective alternative in steroid-refractory/resistant cGvHD. There is inequality in access, and a dedicated reimbursement tariff, however, should be introduced to overcome these barriers., (Copyright © 2015 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Poverty is correlated with negative health outcomes in pediatric primary care and subspecialties; its association with childhood hematopoietic stem cell transplantation (HSCT) patterns of care and clinical outcomes is not known. We describe family-reported financial hardship at a primary referral center in New England and explore the relationship between measures of poverty and patterns of care and clinical outcomes. Forty-five English-speaking parents of children after allogeneic HSCT in the prior 12 months completed a 1-time survey (response rate 88%). Low-income families, defined as ≤200% federal poverty level (FPL), were compared with all others. Eighteen (40%) families reported pre-HSCT incomes ≤200% FPL. Material hardship, including food, housing, or energy insecurity was reported by 17 (38%) families in the cohort. Low-income families reported disproportionate transplantation-related income losses, with 7 (39%) reporting annual income losses of >40% compared with 2 (18%) wealthier families (P = .02). In univariate analyses, 11 (61%) low-income children experienced graft-versus-host disease (GVHD) of any grade in the first 180 days after HSCT compared with 2 (7%) wealthier children (P = .004). We conclude that low income and, in particular, material hardship, are prevalent in a New England pediatric HSCT population and represent targets for improvement in quality of life. The role of poverty in mediating GVHD deserves further investigation in larger studies that can control for known risk factors and may provide a targetable source of transplantation-associated morbidity., (Copyright © 2015 American Society for Blood and Marrow Transplantation.

Because of expanding indications and improvements in supportive care, the utilization of blood and marrow cell transplantation (BMT) to treat various conditions is increasing exponentially, and currently more than 60,000 BMTs are performed annually worldwide. By the year 2030, it is projected that the number of BMT survivors will increase 5-fold, potentially resulting in one half of a million survivors in the United States alone. As the majority of survivors now live beyond the first 2 years after BMT, they are prone to a unique set of complications and late effects. Until recently, BMT experts assumed responsibility for almost all of the care for these survivors, but now oncologists/hematologists, pediatricians, and internists are involved frequently in offering specialized care and preventive services to these survivors. To integrate and translate into clinical practice the unique BMT survivorship issues with current preventive guidelines, a team effort is required. This can be facilitated by a dedicated "long-term-follow-up (LTFU)" clinic that provides lifelong care for BMT survivors. In this review, we first illustrate with clinical vignettes the need for LTFU and then focus upon the following: (1) types of LTFU clinic models, (2) challenges and possible solutions to the establishment of LTFU clinic, and (3) vulnerable transition periods., (Copyright © 2015 American Society for Blood and Marrow Transplantation.

Reduced intensity conditioning (RIC) regimens have allowed older patients and those with comorbidities to receive hematopoietic cell transplantation (HCT). We analyzed medical costs from the beginning of conditioning to 100 days after HCT for 484 patients and up to 2 years for 311 patients who underwent a RIC HCT at two institutions from January 2008 to December 2010. Multiple linear regression was used to analyze the association between clinical variables, center effect, and costs. Patient and transplant characteristics were comparable between the sites, although differences were seen in pretransplant performance scores. Significant predictors for lower costs for the first 100 days included a diagnosis of lymphoma/myeloma and use of human leukocyte antigen-matched related donors. Grade II-IV acute graft-versus-host disease (GVHD) was associated with higher costs. The overall short-term costs between the two institutions were comparable when adjusted for clinical variables (p = .43). Late costs between 100 days and 2 years after HCT were available for one cohort (n = 311); median costs during this period were $39,000 and accounted for 39% of costs during the first 2 years. Late costs were not associated with any pretransplant variables, but were higher with extensive chronic GVHD and death. After adjustment for clinical characteristics, the overall costs of the RIC transplants were similar between the two institutions despite different management approaches (inpatient vs. outpatient conditioning) and accounting methodologies. Use of unrelated/alternative donors, transplant for diseases other than lymphoma or myeloma, and acute GVHD were predictors for higher early costs, and extensive chronic GVHD and death were associated with higher late costs., (©AlphaMed Press.)

BK virus (BKV) reactivation has been increasingly associated with the occurrence of late-onset hemorrhagic cystitis (HC) after allogeneic hematopoietic SCT (allo-HSCT) resulting in morbidity and sometimes mortality. We investigated the incidence, risk factors and outcome of BKV-HC in 323 consecutive adult patients undergoing allo-HSCT over a 5-year period. BK viremia values for HC staging were evaluated, as well as the medico-economic impact of the complication. Forty-three patients developed BKV-HC. In univariate analysis, young age (P=0.028), unrelated donor (P=0.0178), stem cell source (P=0.0001), HLA mismatching (P=0.0022) and BU in conditioning regimen (P=0.01) were associated with a higher risk of developing BKV-HC. In multivariate analysis, patients receiving cord blood units (CBUs) (P=0.0005) and peripheral blood stem cells (P=0.011) represented high-risk subgroups for developing BKV-HC. BK viremia was directly correlated to HC severity (P=0.011) with a 3 to 6-log peak being likely associated with grades 3 or 4 HC. No correlation was found between BKV-HC and acute graft versus host disease or mortality rate. Patients with BKV-HC required a significantly longer duration of hospitalization (P<0.0001), more RBC (P=0.0003) and platelet transfusions (P<0.0001). Over the 5-year study period, the financial cost of the complication was evaluated at \[euro]2 376 076 ($3 088 899). Strategies to prevent the occurrence of late-onset BKV-HC after allo-HSCT are urgently needed, especially in CBU and peripheral blood stem cell recipients. BK viremia correlates with the severity of the disease. Prospective studies are required to test prophylactic approaches.

Thirty-day readmission (30-DR) has become an important quality-of-care measure. Allogeneic hematopoietic cell transplantation (allo-HCT) presents a medical setting with higher readmission rates. We analyzed factors affecting 30-DR and its impact on patient outcomes and on health care costs in 91 patients who underwent reduced-toxicity conditioning (RTC) allo-HCT with fludarabine and busulfan. The patient cohort was divided into 2: the readmission group (R-gp) or the no-readmission group (NR-gp). Overall, 38% (n = 35) required readmission with a median time to readmission of 14 days. In multivariate analysis, only documented infection during the index admission predicted 30-DR, P = .01. With a median follow-up of 18 months (range, 1 to 69) for surviving patients, the 2-year overall survival was 49% and 58% in the R-gp and NR-gp respectively, P = .48. The 1-year nonrelapse mortality in R-gp and NR-gp was 18% and 13% respectively, P = .43. The median post-transplantation hospital charges in the R-gp and NR-gp were $85,115 (range, $32,015 to $242,519) and $45,083 (range, $10,715 to $485,456), P = .0002. In conclusion, only documented infections during the index hospitalization influenced 30-DR after RTC allo-HCT. Although 30-DR did not adversely affect mortality or survival, it was associated with significantly increased 100-day post-transplantation hospital charges, thus supporting its role as a quality-of-care measure in allo-HCT patients., (Copyright © 2014 American Society for Blood and Marrow Transplantation.

Background: A second allogeneic transplantation after a prior allogeneic (allo-allo) or autologous (auto-allo) hematopoietic cell transplantation (HCT) is usually performed for graft failure, disease recurrence, secondary malignancy, and, as planned, auto-allo transplantation for some diseases., Methods: We sought to describe the costs of second allogeneic HCT and evaluate their relationship with patient characteristics and posttransplantation complications. Clinical information and medical costs for the first 100 days after transplantation of 245 patients (allo-allo, 55; auto-allo, 190) who underwent a second HCT between 2004 and 2010 were collected., Results: Median costs of the second allogeneic HCT were U.S. $151,000 (range, U.S. $62,000-405,000) for the allo-allo group and U.S. $109,000 (range, U.S. $26,000-490,000) for the auto-allo group. Median length of hospital stay was 23 days (range, 0-76) for the allo-allo group and 9 days (range, 0-96) for the auto-allo group. Only the year of transplantation and posttransplantation complications were significantly associated with costs in both groups when both pre- and posttransplantation variables were considered. The overall costs of the second HCT were higher than the first in the allo-allo group. For the auto-allo group, there was no difference between the costs whether preformed as a planned tandem or as salvage for relapse., Conclusions: Our results suggest that second allogeneic HCT is costly, particularly if it follows a prior allogeneic transplantation, and is driven by the costs of complications.

Graft-versus-host disease (GvHD) is a common complication following haematopoietic stem cell transplant but little is published about the impact of this condition on hospital readmission rates. We report a retrospective analysis of readmission rates and associated costs in 187 consecutive allogeneic transplant patients to assess the impact of GvHD. The overall readmission rate was higher in patients with GvHD (86% (101/118) vs. 59% (41/69), p < 0.001). The readmission rate was higher both in the first 100 d from transplant (p = 0.02) and in the first year following transplant (p < 0.001). 151/455 (33%) of all readmission episodes occurred within 100 d of transplant. The mean number of inpatient days was significantly higher in patients with grade III/IV acute GvHD (101 d) compared with those with grade I/II GvHD (70 d; p = 0.003). The mean cost of readmission was higher in patients with GvHD (£28 860) than in non-GvHD patients (£13 405; p = 0.002) and in patients with grade III/IV GvHD (£40 012) compared with those patients with grade I/II GvHD (£24 560; p = 0.038). Survival was higher in those with grade I/II GvHD (55%) compared to grade III/IV GvHD (14%; p < 0.001). This study shows the high economic burden and poor overall survival associated with grade III/IV GvHD., (© 2012 John Wiley & Sons A/S.)

Hematopoietic cell transplantation (HCT) remains the sole available curative option for patients with β-thalassemia major. Expanded and improved supportive therapies for thalassemia now routinely extend the life span of affected individuals well into adulthood. Consequently, in regions of the world where this care is readily available, HCT has been pursued infrequently, in part owing to concerns about an expected lack of balance between risks and benefits. More recently, however, recognition of significant health problems in older patients with thalassemia, along with recognition of increased risks of graft-versus-host disease (GVHD), graft rejection, and impaired organ function leading to inferior HCT outcomes in this particular group, seem to be turning the wheels and tipping the balance again in the direction of consideration for earlier HCTs. In contrast, in countries where thalassemia is most prevalent (>100,000 new children born each year in Middle East and southeast Asia), lack of supportive care standards together with often insufficient access to dedicated health care facilities, results in the majority of these children not reaching adulthood, further supporting the need for expanded access to HCT for these patients. The cost of HCT is equivalent to that of a few years of noncurative supportive care, such that HCT in low-risk young children with a compatible sibling is justified not only medically and ethically but also financially. International cooperation can play a major role in increasing access to safe and affordable HCT in countries where there is a considerable shortage of transplantation centers. In this article, we review the current status of bone marrow transplantation for thalassemia major, with particular emphasis on a global prospective., (Copyright © 2013 American Society for Blood and Marrow Transplantation.

Background: Chronic graft-versus-host disease (cGvHD) is the leading cause of late nonrelapse mortality (transplant-related mortality) after hematopoietic stem cell transplant. Given that there are a wide range of treatment options for cGvHD, assessment of the associated costs and efficacy can help clinicians and health care providers allocate health care resources more efficiently., Objective: The purpose of this study was to assess the cost-effectiveness of extracorporeal photopheresis (ECP) compared with rituximab (Rmb) and with imatinib (Imt) in patients with cGvHD at 5 years from the perspective of the Spanish National Health System., Methods: The model assessed the incremental cost-effectiveness/utility ratio of ECP versus Rmb or Imt for 1000 hypothetical patients by using microsimulation cost-effectiveness techniques. Model probabilities were obtained from the literature. Treatment pathways and adverse events were evaluated taking clinical opinion and published reports into consideration. Local data on costs (2010 Euros) and health care resources utilization were validated by the clinical authors. Probabilistic sensitivity analyses were used to assess the robustness of the model., Results: The greater efficacy of ECP resulted in a gain of 0.011 to 0.024 quality-adjusted life-year in the first year and 0.062 to 0.094 at year 5 compared with Rmb or Imt. The results showed that the higher acquisition cost of ECP versus Imt was compensated for at 9 months by greater efficacy; this higher cost was partially compensated for (€517) by year 5 versus Rmb. After 9 months, ECP was dominant (cheaper and more effective) compared with Imt. The incremental cost-effectiveness ratio of ECP versus Rmb was €29,646 per life-year gained and €24,442 per quality-adjusted life-year gained at year 2.5. Probabilistic sensitivity analysis confirmed the results. The main study limitation was that to assess relative treatment effects, only small studies were available for indirect comparison., Conclusion: ECP as a third-line therapy for cGvHD is a more cost-effective strategy than Rmb or Imt., (Copyright © 2012 Elsevier HS Journals, Inc.

We wanted to evaluate factors associated with high costs after allogeneic haematopoietic SCT (HSCT). We collected all in-patient and outpatient costs during the first year after HSCT over 5 years, from 2003 to 2007. Mean 1-year costs per patient were \[euro]141,493 (95% confidence interval (95% CI)=125,019-157,967). Patients treated with non-myeloablative conditioning (NMC) had reduced costs, but patients treated with reduced-intensity or myeloablative conditioning had similar 1-year costs. Multivariate analysis showed that increased 1-year costs were seen in post-transplant complications: rejection (relative hazard (RH) 1.24, P<0.001), acute GVHD of grades III-IV (1.31, P<0.001) and invasive fungal infection (1.15, P=0.02). In addition, increased costs were associated with re-transplantation (1.21, P=0.001), mesenchymal stem-cell therapy (1.26, P<0.001), unrelated donor transplants (1.20, P=0.002) and the need for G-CSF treatment due to poor engraftment (1.12, P=0.047). In patients without any of these risk factors, mean 1-year costs were \[euro]84,773 (95% CI=71,145-98,400) (n=51). With three risk factors, the cost increased to \[euro]249,775 (95% CI=166,824-332,727) (n=14). To conclude, major complications increased the costs of HSCT. Unrelated donor transplants were more expensive than HLA-identical sibling transplants. Costs were reduced in patients treated with NMC.

Even though the overall outcome after allogeneic transplant has improved significantly in the last decades, late infectious diseases are still the most important causes of late morbidity and mortality. Here, impaired immune reconstitution and therapy of chronic graft-versus-host disease (GVHD) represent the major risk factors. In this review, we give a comprehensive overview of late infectious complications and summarize possible diagnostic and therapeutic interventions to prevent these complications., (Copyright © 2012 Elsevier Inc.

The objective of this study was to evaluate the cost-effectiveness of posaconazole versus fluconazole for the prevention of invasive fungal infections (IFI) in graft-versus-host disease (GVHD) patients in the Netherlands. A decision analytic model was developed based on a double-blind randomized trial that compared posaconazole with fluconazole antifungal prophylaxis in recipients of allogeneic HSCT with GVHD who were receiving immunosuppressive therapy (Ullmann et al., N Engl J Med 356:335-347, 2007). Clinical events were modeled with chance nodes reflecting probabilities of IFIs, IFI-related death, and death from other causes. Data on life expectancy, quality-of-life, medical resource consumption, and costs were obtained from the literature. The total cost with posaconazole amounted to 9,428 (95% uncertainty interval 7,743-11,388), which is 4,566 (2,460-6,854) more than those with fluconazole. Posaconazole prophylaxis resulted in 0.17 (0.02-0.36) quality adjusted life year (QALY) gained compared to fluconazole prophylaxis, corresponding to an incremental cost effectiveness ratio (ICER) of 26,225 per QALY gained. A scenario analysis demonstrated that at an increased background IFI risk (from 9% to 15%) the ICER was 13,462 per QALY. Given the underlying data and assumptions, posaconazole prophylaxis is expected to be cost-effective relative to fluconazole in recipients of allogeneic HSCT developing GVHD in the Netherlands. The cost-effectiveness of posaconazole depends on the IFI risk, which can vary by hospital.

Evaluation of: Machnicki G, Ricci JF, Brennan DC, Schnitzler MA. Economic impact and long-term graft outcomes of mycophenolate mofetil dosage modifications following gastrointestinal complications in renal transplant recipients. Pharmacoeconomics 26(11), 951-967 (2008). This commentary discusses findings from an observational study designed to determine the 3-year clinical and economic impact of dose reduction or discontinuation of mycophenolate mofetil after the first gastrointestinal complication in patients after kidney transplantation. The authors used data from the US Renal Data System to demonstrate that dosage reduction or discontinuation of mycophenolate mofetil in the first 6 months after diagnosis of gastrointestinal complications is associated with a significantly increased risk of graft failure and increased healthcare costs in adult renal transplant recipients. This article highlights the clinical significance as well as some of the shortcomings of the authors' findings. The introduction of mycophenolate mofetil has clearly improved renal transplant outcomes; however, there is a need for well-planned studies examining pharmacokinetics and pharmacodynamics of mycophenolate mofetil and strategies for reducing gastrointestinal side effects.

We compared inpatient and outpatient costs alongside clinical outcomes associated with hematopoietic cell transplantation between 2000 and 2003 with high-dose regimens (HDCT, n=185) and with reduced intensity regimens (RICT, n=90) from human leukocyte antigen (HLA)-matched donors for patients with hematological malignancies. With a comparable median follow-up of 3 years, long-term clinical outcomes, including cumulative incidence of chronic graft-vs-host disease, disease-free survival and overall survival, were similar between the two groups. In the univariate analysis, median costs for the first 100 days ($104,380 vs $42,149) and 1 year ($128,253 vs $80,499) in the HDCT group were higher than those in the RICT group. Median days of hospitalization are also higher for HDCT recipients (39 vs 21), although the number of outpatient clinic visits for HDCT recipients were fewer compared to that for RICT recipients (16 vs 25) during the first year. Adjusting for patient characteristics, RICT recipients had approximately 16 fewer days of hospitalization and cost $53,030 less than HDCT recipients within the first year after transplantation. Our data suggest that substantially lower costs and fewer days of hospitalization within the first year after RICT procedures can be obtained with no compromise of long-term clinical outcomes compared to HDCT procedures.

To determine development of treatment, costs, and survival for patients with grades III/IV acute graft-versus-host disease (GVHD), data from 88 patients with grades III/IV acute GVHD were collected. The patients were divided into three groups: patients who received transplants from 1977 through 1989 (group A), 1990 through 1999 (group B), and 2000 through 2004 (group C). The costs for treatment, enumerated to year 2003 costs, were calculated. An increased 1-year survival rate was found in group C, at 21% versus 9% and 8% for groups A and B, respectively (P=0.02). Death by acute GVHD was increased by repeat transplantation (P<0.001), grade IV acute GVHD (P<0.001), human leukocyte antigen mismatch (P=0.009), and transplantation before 2000 (P=0.015). Transplantation after 1990 (P=0.003) and grade IV acute GVHD (P=0.03) were associated with higher treatment costs. It was found that the time the patients had GVHD did not differ among the three groups. In conclusion, the costs and survival rates associated with severe acute GVHD has increased in recent years.

Unrelated-donor marrow transplantation is a potential option for transplant candidates lacking a compatible related donor. The T-cell Depletion Study compared the 3-year disease-free survival for patients receiving T-cell-depleted (TCD) donor marrow (n = 203) vs unmanipulated donor marrow with methotrexate and cyclosporine (M/C) (n = 207). Hospital costs during index admission were documented with billing data, while hospital costs during subsequent 6-month follow-up were estimated from case report forms. Patients with index admission billing were included in the analysis (TCD = 119, M/C = 127). Total hospital length of stay (LOS) was similar across groups, with medians 47.0 days for TCD and 52.0 days for M/C (P = 0.72). Total hospital costs were comparable, 145,115 dollars vs 141,981 dollars (P = 0.63) for TCD and M/C, respectively. However, controlling for site and patient characteristics, TCD was associated with a 12.1% reduction in LOS for the index admission (95% CI -19.4%, -4.3%). Independent of treatment, HLA matching (6/6) was associated with an 8.6% (95% CI -17.4%, +1.2%) reduction in the index admission LOS, while cost was lower by 15.8% (95% CI -26.7%, -3.3%). Treatment costs were similar for TCD and M/C study groups. Savings on reduced cost for treating acute graft-versus-host disease were likely offset by increase in serious infections in the TCD arm.

Background: Allogeneic hematopoietic stem-cell transplantation is a widely used, cost-intensive procedure. Our purpose was to estimate costs and determine cost predictors., Methods: We used data from a prospective French study comparing four doses of immunoglobulins. Resource use of hematopoietic stem-cell transplant recipients during the first 6 months posttransplant, both inpatient and ambulatory costs, in 85 patients from five centers were collected prospectively and costed. Baseline data and clinical events were retrieved. Protocol-driven costs were excluded. Multivariable analysis evaluated the association between costs and patient's pretransplant status and transplant-related complications. Because of the absence of differences in outcome among the four randomization groups, cost data for all patients were pooled., Results: Total costs per patient were the following: mean 76,237 Euros; standard deviation 32,565 Euros; median 69,516 Euros; range 183,758 to 14,761Euros. The major cost driver was hospital days. No association was found between costs and baseline status. The "predictors" of higher costs (adding an average 20,000 Euros/patient) were the occurrence of transplant-related complications: graft-versus-host disease and repeated infections that were unpredictable before transplant in this homogeneous group of patients., Conclusion: Our data highlight the discrepancy between the Diagnosis Related Group prospective payment system and actual costs. The actual cost of geno-identical stem-cell transplantation results from posttransplant complications that cannot be predicted prospectively and require ex post cost adjustment.

Mycophenolate mofetil is an important drug in the modern immunosuppressive arsenal. Mycophenolate mofetil is the semisynthetic morpholinoethyl ester of mycophenolate acid. Mycophenolate acid prevents T and B cell proliferation by specifically inhibiting a purine pathway required for lymphocyte division. This paper extensively reviews the experience of mycophenolate mofetil use in liver transplant recipients. In randomised trials, mycophenolate mofetil decreased the rate of acute rejection after liver transplantation, without a significant increase of septic complications. However, so far, there are no data indicating that mycophenolate mofetil increases liver transplant patient or graft survivals. Mycophenolate mofetil is interesting because of its particular side effects profile, which is very different from the other immunosuppressants. The absence of mycophenolate mofetil nephrotoxicity is of specific interest in liver recipients with impairment of renal function. The monitoring of mycophenolate acid area under the concentration time curve might be interesting to limit side effects and provide better clinical efficacy but the exact role of mycophenolate acid monitoring in liver recipients has yet to be further evaluated in large series.

T-cell depletion (TCD) and immunosuppressive medications (ISTs) are 2 methods used for graft-versus-host disease (GVHD) prophylaxis in unrelated donor (URD) transplantation. However, comparisons of the clinical outcomes including quality of life and direct medical costs associated with each type of procedure have not been reported. We reviewed 48 TCD and 98 IST procedures performed from 1/1/97 to 12/31/99 at the Dana-Farber Cancer Institute, Boston, MA. With a median follow-up of 1.5 years for survivors, no differences were seen in relapse, acute GVHD, and overall survival between TCD and IST patients. Multivariable Cox modeling showed that age of 50 years or less (P =.002) and low-risk disease (P =.001) predicted survival, but method of GVHD prophylaxis (P =.6) and degree of human leukocyte antigen (HLA) matching (P =.8) did not. A subset of patients (53%) completed quality of life surveys prior to and at 6 and 12 months after transplantation; participation in the quality of life study was not associated with clinical characteristics and outcomes. No differences were seen in quality of life scores prior to transplantation, and changes over time were similar between groups. Costs ($113 000 vs $155 000, P <.0001) and total hospital days (34 vs 46, P =.0006) were significantly lower for patients undergoing TCD procedures. As prospective, randomized studies comparing methods of GVHD prophylaxis are performed, assessment of quality of life and costs should be included to fully understand the overall impact of each intervention.

A total of 254 extracorporeal photochemotherapy (ECP) procedures were performed in 8 children (median age 10 years; range 5-15) with extensive resistant chronic graft-versus-host disease (GVHD). ECP was carried out in the pediatric environment using a Cobe Spectra separator and UV-MATIC irradiator. A peripheral venous with a single-lumen permanent central catheter access (69% of ECP-apheresis) or a dual-lumen permanent central catheter access (26% of ECP-apheresis) were used preferentially. A median platelet decrease of 17% (0-71) (p = 0.0001) and median hemoglobin level decrease of 15 g/L (0-31)(p = 0.0001) were noted following each ECP-apheresis. However, none of the patients had profound thrombocytopenia or anemia. Two minor episodes of catheter related-bacteriemia (Staphylococcus aureus) were noted (2310 catheter-days). A negative correlation was found between lymphocyte collection efficacy (median = 38%) and pre ECP-apheresis lymphocyte count (r = 0.4, p = 0.00001). The median of 5 x 10(7) lymphocytes/kg (0.1-50.10(7)/kg) was irradiated in each procedure. All patients are alive and well, and 7/8 experienced a dramatic improvement in their cutaneous status. Liver and gut disease resolved completely in 4/6 and 5/5 patients, respectively. In all patients, a concomitant immunosuppressive therapy was stopped (5/8) or considerably reduced (3/8). Five patients with more than 2 years follow-up after discontinuation of ECP are in remission with no immunosuppression treatment. They have normal growth rates and normal school and sport activity. Our study shows that ECP is beneficial, well tolerated, and can be safely used for chronic GVHD treatment even in young children with low body weight and a poor performance status. We believe that having a dedicated pediatric environment together with an experienced, motivated, and specifically pediatric team is of crucial importance for improving patient's acceptance of this long-term therapeutic program.

Purpose: Few studies have formally evaluated the relationship between costs, baseline patient characteristics, and major complications of stem-cell transplantation. We sought (1) to determine whether obtaining baseline information enabled identification of patients whose treatments would be the most costly and (2) to estimate inpatient costs for managing specific transplantation complications., Patients and Methods: We collected inpatient costs and clinical information for 236 consecutive patients undergoing transplantation at a single institution between July 1, 1994, and February 20, 1997. Multivariable linear regression was used to evaluate the associations between baseline patient characteristics and costs of hospitalization for initial transplantation and between clinical events and such costs., Results: The median initial inpatient cost in 1997 dollars was $55,500 for autologous transplantation (range, $28,200 to $148,200) and $105,300 for allogeneic transplantation (range, $32,500 to $338,000). When only baseline variables were considered, use of a mismatched allogeneic donor and year of transplantation were significant predictors of costs. No characteristics predicted which patients would incur the highest 10% of costs. When clinical events were considered, infection and in-hospital death were associated with higher costs in autologous transplant recipients ($18,400 and $20,500, respectively), whereas infection, veno-occlusive disease, acute graft-versus-host disease, and death were predicted to add between $15,300 and $28,100 each to allogeneic transplantation costs., Conclusion: We were not able to identify before transplantation the patients whose treatments would be the most costly. However, the association between clinical complications and higher costs suggests that prevention may have significant economic benefits. Interventions that decrease these complications may have favorable cost-benefit ratios even if they do not affect overall survival.

Allogeneic peripheral blood stem cell transplantation (alloPBSCT) is an emerging technology. As this technology develops, transplant centers are concerned with looking for technologic advances that will result in improvements in clinical outcomes and lower costs. We provide comparative estimates of costs and resource use for alloPBSCT in comparison to allogeneic bone marrow transplantation (alloBMT) for persons with hematologic malignancies from the time of harvest to 100 days post transplant. A retrospective, cost-identification analysis was conducted for patients in two consecutive phase II clinical trials at the University of Nebraska Medical Center. Identical preparative regimens, graft-versus-host disease prophylaxis, post-transplant hematopoietic colony-stimulating factor treatment regimens, and discharge criteria were used. Total median costs were $18,304 lower for alloPBSCT, with lower costs during recovery; specifically for hospitalization, platelet products, hematopoietic growth factors, intravenous hyperalimentation, supportive care agents, supplies, and antibacterial agents. This study provides preliminary evidence for short-term cost savings associated with alloPBSCT. However, concerns exist over the potential for higher costs due to preliminary reports of higher rates of chronic graft-versus-host disease, as well as more intensive induction regimens that may result in lower relapse rates. The premature adoption of new technologies based on short-term economic factors, in the absence of adequate clinical trial data, may prove to be ill-advised, particularly for complex medical treatments such as allogeneic transplantation.

Allogeneic peripheral blood progenitor cell (PBPC) transplants are an alternative to BMT, although G-CSF mobilization dose, timing of pheresis and risk of GVHD are not well defined. We compared harvest characteristics, donor and recipient outcomes and costs of two PBPC transplant strategies with historical controls who received BMT. Twenty donors mobilized with four daily s.c. G-CSF doses (5 microg/kg/day) (group 1) and 20 mobilized with 10 microg/kg/day G-CSF (group 2) were compared with 20 BM controls (group 3). G-CSF and phereses were well tolerated. Four of 40 PBPC donors required femoral catheter placement. At least 2.5 x 10(6) CD34+/kg recipient weight were collected with two phereses in 19/20 donors (group 1) and 18/20 donors (group 2). Time to neutrophil (18 vs 20 vs 22 days, P = 0.02) and platelet (21 vs 24 vs 27 days, P = 0.005) engraftment was shorter in the PBPC groups (group 2 vs group 1 vs group 3) but secondary engraftment outcomes were not different. The incidence of grade 2-4 aGVHD was higher in the low-dose G-CSF group (group 1) but there was no difference in cGVHD, 100-day or 1-year survival. The mean PBPC transplant cost (group 1) at first hospital discharge was less than BM (group 3) ($34,643 vs $37,354) but the mean overall cost for both groups was similar at 100 days ($46,334 vs $46,083). Allogeneic PBPC transplant with short course, low-dose G-CSF mobilization is safe, feasible and cost equivalent to allogeneic BMT.

To assess how payer costs for allogeneic BMT relate to patient characteristics and clinical complications, a retrospective cohort study of 402 persons undergoing allogeneic BMT between 1980 and 1987 at a university-based BMT center was designed to determine total inpatient payer costs, including hospital and physician costs, and number of days hospitalized during the first 180 days following BMT. The average total inpatient payer cost (in 1990 dollars) during the first 180 days following BMT was $208,410. Inflation-adjusted inpatient payer costs increased from $227,806 in 1980 to $308,545 in 1983, and then decreased to $156,163 by 1987. In multivariate analysis, inpatient payer costs were strongly associated with occurrence of CMV infection (increase of $53,517; p = 0.0001) or acute GVHD (increase of $46,500; p = 0.001), and significantly associated with malignant (versus non-malignant) disease (decrease of $36,633; p = 0.05), even after adjusting for length of survival and year of BMT. Inpatient payer costs were not related to patient age, sex or race. Despite recent reductions in inpatient payer costs for BMT, CMV infection and acute GVHD continue to be associated with tremendous costs to third party payers. Further reductions in the costs of BMT may require improved prevention of CMV infection and GVHD.
