A review of the costs, cost-effectiveness and third-party charges of bone marrow transplantation

Nursing interventions in autologous stem cell transplantation for autoimmune diseases

AIMS

To identify clinical symptoms and nursing interventions for stem cell therapy in autoimmune diseases.

DESIGN

This is a retrospective, cross-sectional study.

METHODS

This study was undertaken with patients diagnosed with type 1 diabetes or multiple sclerosis, undergoing autologous haematopoietic stem cell transplantation from January 2004 - December 2018. Data were registered in a questionnaire, taken during the conditioning regimen comprising cyclophosphamide and rabbit anti-thymocyte globulin. Descriptive statistics and Fisher's exact test were used for data analysis.

RESULTS

There were 68 and 23 patients in the multiple sclerosis and type 1 diabetes groups respectively. Skin rash, nausea, vomiting and fever were more frequent and diverse in the type 1 diabetes group. Steroids were used as prophylaxis for anti-thymocyte globulin-associated allergic reactions in 97% of multiple sclerosis patients. Most of the identified symptoms and nursing interventions were more associated with one or other disease group (p < .05) and were more frequent in the type 1 diabetes group.

CONCLUSION

Patients with autoimmune diseases who underwent stem cell therapy present differences in their repertoire of adverse events and require disease-specific nursing actions.

IMPACT

Our results may enable nurses to establish transplant and disease-specific guidelines to improve prevention and management of adverse events and therefore optimize patient care and therapeutic success.

Do declining private insurance coverage rates influence pediatric hospital charging practices?

OBJECTIVE

To analyze trends in primary payer composition for pediatric hospitalizations and insurance coverage rates from 2000 to 2006 and possible effects on hospital charging practices.

DESIGN

We documented national trends in hospital charge-to-cost ratios and primary payer mixes for pediatric discharges from 2000 to 2006 using the Healthcare Cost and Utilization Project (HCUP) Kid's Inpatient Database (KID). We then performed regression analyses at the hospital level to analyze associations between pediatric insurance coverage rates and hospital charge-to-cost ratios.

RESULTS

We found pediatric inpatient charge-to-cost ratios increased dramatically during study period. Charge-to-cost ratios were higher for hospitals located in states with either higher uninsurance rates or a public-private coverage mix that was skewed towards public coverage.

CONCLUSIONS

This study provides evidence of both important changes in pediatric health insurance distribution in the United States and hospital charging practices.

Cost effectiveness of rituximab maintenance therapy in follicular lymphoma: long-term economic evaluation

BACKGROUND

Rituximab maintenance therapy was shown to significantly extend overall survival (OS) and progression-free survival (PFS) in relapsed/refractory follicular lymphoma (FL) in the pivotal EORTC 20981 trial.

OBJECTIVE

To assess the long-term costs and cost effectiveness of rituximab maintenance therapy after induction therapy versus current standard practice (observation) from the French National Health Service perspective.

METHODS

A lifetime transition model was developed comparing rituximab maintenance with observation. PFS and OS were obtained from the EORTC 20981 trial with a median follow-up of 28 months and extrapolated from 2-year Kaplan-Meier curves using a Weibull distribution. PFS and OS benefits of rituximab were conservatively assumed to last only 5 years. Utility data were obtained from a multicentre observational study using the EQ-5D questionnaire. Direct medical costs were obtained from French official sources. All costs are reported in euro, year 2006 values.

RESULTS

The EORTC 20981 study demonstrated that rituximab maintenance was effective in the management of relapsed/refractory FL. The model results showed that life expectancy and QALYs were increased by 22% and 28%, respectively, in patients treated with rituximab. The incremental cost-effectiveness ratios (ICERs) were euro 7612 per life-year gained and euro 8729 per QALY gained. In a one-way sensitivity analysis, most of the ICERs fell within the range of euro 7000-12,000. The results tend to show that rituximab maintenance therapy may be a cost-effective strategy in the management of relapsed/refractory FL in France, with ICERs below those observed for other therapies in the oncology field. The cost of rituximab was partly offset by the lower cost of relapse due to a longer time in the disease-free health state for patients in the rituximab arm.

Outcomes and charges of elderly patients with acute myeloid leukemia

A retrospective database analysis was conducted to evaluate hospitalization outcomes and charges among elderly acute myeloid leukemia (AML) patients. The data source was a longitudinal (2000-2003) inpatient database from 28 US hospitals. Data on 275 AML patients aged 60 and older were analyzed for demographic and treatment characteristics, hospital mortality, length of stay (LOS), overall days of stay (DOS), and charges across multiple admissions. Multivariate modeling was performed to determine factors that influenced outcomes. Overall, 115 (41.8%) patients received inpatient chemotherapy (CT); most (90.4%) received it on the first admission. Of all initial CT regimens 40.9% consisted of a single agent. The mean LOS for initial hospitalization was 23.0 (SD 21.8) days for patients who received CT and 6.7 (SD 7.5) days for those who did not. One quarter (25.3%) of initial hospitalizations resulted in death. On initial hospitalization, mean total charges were $113,118 (SD $220,417) for patients who received CT and $43,999 (SD $190,533) for those who did not; for both groups mean charges were higher than respective subsequent admission charges. Overall, in-hospital mortality did not differ significantly between on-CT and off-CT groups (43.5 and 38.8%, respectively). In multivariate modeling, CT was significantly associated (P < 0.0001) with increased charges and LOS. Elderly patients with AML incurred substantial hospital charges and inpatient mortality. The highest charges and a substantial number of deaths occurred during first admission. Although treatment with CT was associated with increased charges and days in-hospital, inpatient mortality in the two groups was found to be similar.

The availability of full match sibling donors and feasibility of allogeneic bone marrow transplantation in Brazil

The feasibility of allogeneic bone marrow transplantation (alloBMT) in a developing country has not yet been demonstrated. Many adverse factors including social and economic limitations may reduce the overall results of this complex and expensive procedure. Our objective was to characterize the most important clinical, social and economic features of candidates for transplantation and their potential donors as well as the influence of these factors on overall survival in a retrospective and exploratory analysis at a university hospital. From July 1993 to July 2001, candidates for BMT were referred to the Bone Marrow Transplantation Unit by Hematology and Oncology Centers from several regions of Brazil. A total of 1138 patients were referred to us as candidates for alloBMT. Median age was 25 years (range: 2 months-60 years), 684 (60.1%) were males and 454 (39.9%) were females. The clinical indications were severe aplastic anemia and hematological malignancies. From the total of 1138 patients, 923 had HLA-typing; 497/923 (53.8%) candidates had full match donors; 352/1138 (30.8%) were eligible for alloBMT. Only 235 of 352 (66.7%) were transplanted. Schooling was 1st to 8th grade for 123/235 (52.3%); monthly family income ranged from US$60 (7%) to more than US$400 (36%). Overall survival for patients with chronic myeloid leukemia, severe aplastic anemia and acute myeloid leukemia was 58, 60 and 30%, respectively. Thus, overall survival rates for the most frequent hematological diseases were similar to those reported in the International Registry, except for acute myeloid leukemia. This descriptive and exploratory analysis suggests the feasibility of alloBMT in a developing country like Brazil.

Economic aspects of high-dose chemotherapy: a clinician's perspective review

Over the last 15 years, the increased use of high-dose chemotherapy (HDC) has led to a considerable increase in the cost of cancer treatments. After making a general economic analysis of the benefits and costs of healthcare initiatives, this paper considers all of the different phases and elements of HDC, as well as the strategies for reducing basic, indirect and out-of-pocket costs. The cost of HDC has decreased by 40-60% over the last decade and its cost-effectiveness ratios are now similar or only slightly higher than those of other widely accepted medical interventions. However, except in the case of some hematological and paediatric neoplasms, the efficacy of the treatment has not yet been clearly defined and so it should only be used in well-designed clinical trials that should also include prospective cost evaluation measures.

Mobilization, collection, and processing of autologous peripheral blood stem cells: development of a clinical process with associated costs

We surveyed five academic medical centers to develop a clinical process for patients undergoing cytokine mobilization and leukapheresis prior to autologous peripheral blood stem cell transplantation. Costs were obtained from three centers and applied to each component of the pathway. Costs were divided into three categories: (1) pre-apheresis evaluation; (2) process of apheresis; (3) post-apheresis and peripheral blood stem cells processing. All centers participated in the development of the leukapheresis pathway. Because charges vary greatly among institutions, costs were determined from three of the institutions and a mean was calculated for each of the components of the process. Pre-apheresis costs consisted of central line placement, blood work, and the price of cytokine (rhG-CSF). Costs associated with apheresis included professional fees (for physicians and nurses), leukapheresis with stem cell cryopreservation, storage, sterility testing, analysis of circulating CD34+ cell counts, and 1 day of cytokine therapy. The post-apheresis process included thawing with sterility testing along with CD34+ cell number analysis and the performance of clonogenic assays. Total costs were as follows: (1) pre-apheresis, $2711; (2) apheresis, $2990; and, (3) post-apheresis/stem cell processing, $754. This survey from five academic medical centers provides the average costs associated with three main components of the apheresis procedure. Because many patients require multiple aphereses, interventions to achieve target CD34+ cell collections in as few collections as possible would result in significant cost reduction.

Outpatient-based bone marrow transplantation for hematologic malignancies: cost saving or cost shifting?

PURPOSE

To determine whether a shift in care from an inpatient-based to an outpatient-based bone marrow transplantation (BMT) program decreased charges to payers without increasing clinical complications or out-of-pocket costs to patients.

PATIENTS AND METHODS

This nonrandomized prospective cohort study compared clinical and economic outcomes for 132 consecutive BMT patients with hematologic malignancies who received either inpatient- or outpatient-based BMT care.

RESULTS

Seventeen of 132 BMT patients underwent outpatient-based BMT. Compared with the inpatient-based group, the outpatient-based group had a markedly lower mean number of inpatient hospital days (22 v 47; P <.001) and decreased mean inpatient facility charges ($61,059 less per patient; P <.0001) but had higher mean outpatient facility charges ($49,732 higher; P <. 0001). Total professional fees were similar for the groups. The mean total charge to payers was only 7% less ($12,652; P =.21) for outpatient-based BMT than for inpatient-based BMT, but total charge was 34% less for outpatient compared with inpatient BMT ($54,240; P = 0.056) in a subset of patients who had a standard rather than high risk of treatment failure. There was no significant difference between groups in out-of-pocket costs for transportation, lodging, meals, home nursing, household assistance, child care, medication expenses, or unreimbursed medical bills. There also was no significant difference between groups in reported income lost, involuntary unemployment, or months of disability. The two groups had similar rates of major complications, including death, significant acute graft-versus-host disease, and veno-occlusive disease of the liver.

CONCLUSION

Increased use of outpatient-based BMT should produce substantial cost savings for payers without adverse effects on patients for those patients who do not have a high risk of treatment failure.

Marrow-mindedness: a perspective on neuropoiesis

There are pluripotent stem cells in the adult brain that might not be very different from those found in bone marrow. Recent and profound advances in the field of neuropoiesis, which often rely on insights from studies of hematopoiesis and in some instances use cross-paradigms with this field, have already revealed that bone marrow has much in common with so-called 'brain marrow'. Proliferative primogenitors and developmentally regulated molecules are hallmarks of both neuropoiesis and hematopoiesis. This article will focus on recent advances in neuropoiesis within a central core of the mature brain that is referred to as brain marrow, discussing its pluripotency and proliferative capacity, in vitro and molecular assays used in its study, and markers of neuropoietic stem/progenitor cells. As hematopoiesis research has led to the discovery of numerous morphogenetic factors, it is anticipated that studies of neuropoiesis should also uncover many new factors and genes that affect the growth and differentiation of neural cells. Recent breakthroughs in the stem-cell field prompt an inclusion of rationale for the persistence of normal stem/progenitor cells even in the aged brain. By analogy with hematopoiesis research, a thorough investigation of brain marrow should provide basic insights into developmental and persistent neurogenesis while anticipating cell-transplant and gene therapies for debilitating neurological diseases.

The Costs and Cost-Effectiveness of Unrelated Donor Bone Marrow Transplantation for Chronic Phase Chronic Myelogenous Leukemia

Unrelated donor transplantation prolongs survival in some patients with chronic myelogenous leukemia (CML) in chronic phase. However, there are growing concerns about the intensive resources required for this procedure given health care budget constraints. To address this issue, we conducted a study of the costs and cost-effectiveness of unrelated donor transplantation for chronic phase CML. The costs of transplantation were derived from 157 patients from the Brigham and Women’s Hospital (BWH) and the Fred Hutchinson Cancer Research Center (FHCRC). Estimates of the effectiveness of transplantation were taken from our previous work using data from the International Bone Marrow Transplant Registry and the National Marrow Donor Program. The median cost of the first 6 months of care including donor identification, marrow collection, patient hospitalization for transplantation and all outpatient medications and readmissions through 6 months postmarrow infusion was $178,500 (range, $85,000 to $462,400) and the mean was $196,200. Mean costs for patients surviving beyond 6 months posttransplant were significantly lower than for patients dying within that period ($189,700 v $211,000, respectively,P = .03). Posttransplant follow-up costs were high for months 6 to 18, then decreased. The incremental cost-effectiveness of transplantation within 1 year of diagnosis versus -interferon therapy without transplant in the base case of a 35-year-old patient was $51,800/quality-adjusted life year (QALY) gained. Sensitivity analysis showed that most ratios were between $50,000 to $100,000/QALY or within the intermediate zone of acceptable cost-effectiveness ratios.

Blood cell transplantation: concepts and concerns

OBJECTIVES

To provide a review of the concepts and concerns for each phase of blood cell transplantation (BCT).

DATA SOURCES

Review articles, research studies, abstracts, and book chapters related to BCT.

CONCLUSIONS

The evaluation of BCT as a major treatment option for a growing number of diseases will challenge nursing professionals. BCT is a complex process that requires conceptual knowledge as well as technical skills.

IMPLICATIONS FOR NURSING PRACTICE

Comprehending specific concepts related to patient eligibility, mobilization, apheresis, cryopreservation, dose-intensive therapy, reinfusion, and marrow engraftment is essential to providing quality nursing care to patients undergoing BCT.
