Costs of autologous and allogeneic hematopoietic cell transplantation in the United States: a study using a large national private claims database

Five-year direct costs of acute lymphoblastic leukemia pediatric patients undergoing allogeneic stem cell transplant

Aim

To assess the 5-year healthcare resource utilization (HRU) and direct payer costs following allogeneic hematopoietic stem cell transplants (HSCTs) in acute lymphoblastic leukemia pediatric patients using data from two large US administrative databases.

Patients & methods

Among the 209 patients with acute lymphoblastic leukemia, HRU and costs were described over the up to 5 years after the HSCT.

Results

HRU and costs following the HSCTs were substantial. The highest average costs and most intensive HRU were observed within the first year following the HSCTs (49 outpatient visits; 29 laboratory service visits; 68 inpatient days), with a first year cost of US$683,099 and substantial costs over the following years.

Conclusion

HRU and direct costs associated with allogeneic HSCTs are substantial.

Mixed outpatient-inpatient autologous stem cell transplant for multiple myeloma: A cost-saving initiative in a resource constrained environment

Background Although administration of chemotherapy prior to autologous stem cell transplantation in the outpatient setting has been reported as safe and cost-effective, many limitations exist with previously reported methods of transitioning out of the hospital ward. Specifically, lack of a caregiver and distance from treatment facility are key factors particularly in rural settings. Given these limitations, not all institutions have transitioned the transplant process, or even portions of it, to the outpatient setting despite the known benefits. Methods To achieve financial benefit without compromising safety, a novel mixed outpatient-inpatient model was adopted at our institution. Eligible patients receive melphalan in the clinic the day prior to being admitted for peripheral blood stem cell re-infusion where they remain until recovery of myelosuppression. Results In the year since implementation, nineteen total patients received high-dose melphalan prior to autologous stem cell transplantation. Eighteen of these patients successfully received melphalan in the outpatient clinic with admission to the hospital on day zero for infusion of stem cells. No patient experienced any adverse event on the day or evening of chemotherapy or required early admission. The average estimated total reduction in cost per patient to the institution was over US$2,000. When comparing the cost of the chemotherapy drug, melphalan, from the year before and the year after implementation of the mixed model the total annual cost saving was approximately US$90,00 or 53% of the previous year's expenditure. Conclusions The implementation of this mixed outpatient-inpatient model was safe, feasible, and cost-effective.

Economics and Outcome After Hematopoietic Stem Cell Transplantation: A Retrospective Cohort Study

Hematopoietic stem cell transplantation (HSCT) is a lifesaving expensive medical procedure. Hence, more transplants are performed in more affluent countries. The impact of economic factors on patient outcome is less defined. We analyzed retrospectively a defined cohort of 102,549 patients treated with an allogeneic (N = 37,542; 37%) or autologous (N = 65,007; 63%) HSCT. They were transplanted by one of 404 HSCT centers in 25 European countries between 1999 and 2006. We searched for associations between center-specific microeconomic or country-specific macroeconomic factors and outcome. Center patient-volume and center program-duration were significantly and systematically associated with improved survival after allogeneic HSCT (HR 0·87; 0·84-0·91 per 10 patients; p < 0·0001; HR 0·90;0·85-0·90 per 10 years; p < 0·001) and autologous HSCT (HR 0·91;0·87-0·96 per 10 patients; p < 0·001; HR 0·93;0·87-0·99 per 10 years; p = 0·02). The product of Health Care Expenditures by Gross National Income/capita was significantly associated in multivariate analysis with all endpoints (R(2) = 18%; for relapse free survival) after allogeneic HSCT. Data indicate that country- and center-specific economic factors are associated with distinct, significant, systematic, and clinically relevant effects on survival after HSCT. They impact on center expertise in long-term disease and complication management. It is likely that these findings apply to other forms of complex treatments.

Cost-Effectiveness of Autologous Hematopoietic Stem Cell Transplantation for Elderly Patients with Multiple Myeloma using the Surveillance, Epidemiology, and End Results-Medicare Database

In the past decade, the number of autologous hematopoietic stem cell transplants (Auto HSCT) for older patients with multiple myeloma (MM) has increased dramatically, as has the cost of transplantation. The cost-effectiveness of this modality in patients over age 65 is unclear. Using the Surveillance, Epidemiology, and End Results-Medicare database to create a propensity-score matched sample of patients over age 65 between 2000 and 2007, we compared the survival and cost for those who received Auto HSCT to those who did not undergo transplantation but survived at least 6 months after diagnosis, and we calculated an incremental cost-effectiveness ratio (ICER). Two hundred seventy patients underwent transplantation. Median overall survival from diagnosis in those who underwent transplantation was significantly longer than in patients who did not (58 months versus 37 months, P < .001). For patients living longer than 2 years, the median monthly cost during the first year was significantly different, but the middle and last year of life costs were similar. The median cost of the first 100 days after transplantation was $60,000 (range, $37,000 to $85,000). The resultant ICER was $72,852 per life-year gained. Survival after transplantation was comparable to that in those who underwent transplantation patients under 65 years and significantly longer than older patients who did not undergo transplantation. With an ICER less than $100,000/life-year gained, Auto HSCT is cost-effective when compared with nontransplantation care in the era of novel agents and should be considered, where clinically indicated, for patients over the age of 65.

When to recommend allogeneic transplant in multiple myeloma

Utilization of allogeneic transplant in the management of multiple myeloma has been actively pursued for nearly 30 years. In this paper, the existing data for use of transplant is reviewed as primary therapy, as salvage and for genetic high-risk disease. The relative merits of using a matched-unrelated donor vs. an HLA-matched donor and what impact the introduction of the novel agents has on the decision to transplant will be covered.

Economic impact of disease progression following front-line therapy in classical Hodgkin lymphoma

The current study aimed to assess the economic burden of progressive disease among patients with Hodgkin lymphoma (HL) receiving second- or third-line therapy in a large US network of community-based practices. This retrospective, observational cohort analysis used electronic health records to examine adult patients with classical HL who received chemotherapy between 2007 and 2011. Of 291 observations, 112 had non-progressive disease (received only one line of therapy; LOT1), 114 received second-line therapy (LOT2), and 65 received third-line therapy (LOT3). In LOT2, 49 patients (43%) underwent transplant. In LOT3, 13 patients (20%) underwent transplant. The mean total cost per line of therapy was $21 956 in LOT1, $77 219 in LOT2, and $59 442 in LOT3. When transplant was required, the mean total cost per line of therapy increased 7- to 8-fold when compared with the cost of LOT1 (approximately $154 000 for LOT2 and $193 000 for LOT3). Future therapies that intervene as early as possible in the treatment algorithm to prevent or significantly delay relapse will likely result in significant cost savings.

A randomized control trial of a psychosocial intervention for caregivers of allogeneic hematopoietic stem cell transplant patients: effects on distress

Caregivers of patients receiving allogeneic hematopoietic stem cell transplants (Allo-HSCT) serve a pivotal role in patient care but experience high stress, anxiety, and depression as a result. We theorized that a stress management adapted for Allo-HSCT caregivers would reduce distress compared to treatment as usual (TAU). From 267 consecutive caregivers of Allo-HSCT patients approached, 148 (mean=53.5 years, 75.7% female) were randomized to either psychosocial intervention (n=74) or TAU (n=74). Eight 1-on-1 stress management sessions delivered across the 100 day post-transplant period focused on understanding stress, changing role(s) as caregiver, cognitive behavioral stress management, pacing respiration, and identifying social support. Primary outcomes included perceived stress (psychological) and salivary cortisol awakening response (CAR) (physiological). Randomized groups were not statistically different at baseline. Mixed models analysis of covariance (intent-to-treat) showed that intervention was associated with significantly lower caregiver stress 3 months post-transplant (Mean=20.0, CI₉₅=17.9-22.0) compared to TAU (Mean=23.0, CI₉₅=21.0-25.0) with an effect size (ES) of 0.39 (p=0.039). Secondary psychological outcomes, including depression and anxiety, were significantly reduced with ESs of 0.46 and 0.66 respectively. Caregiver CAR did not differ from non-caregiving controls at baseline and was unchanged by intervention. Despite significant caregiving burden, this psychosocial intervention significantly mitigated distress in Allo-HSCT caregivers.

Cost structure and clinical outcome of a stem cell transplantation program in a developing country: the experience in northeast Mexico

BACKGROUND AND OBJECTIVE

Hematopoietic stem cell transplantation (HSCT) in developing countries is cost-limited. Our primary goal was to determine the cost structure for the HSCT program model developed over the last decade at our public university hospital and to assess its clinical outcomes.

MATERIALS AND METHODS

Adults and children receiving an allogeneic hematopoietic stem cell transplant from January 2010 to February 2011 at our hematology regional reference center were included. Laboratory tests, medical procedures, chemotherapy drugs, other drugs, and hospitalization costs were scrutinized to calculate the total cost for each patient and the median cost for the procedure. Data regarding clinical evolution were incorporated into the analysis. Physician fees are not charged at the institution and therefore were not included.

RESULTS

Fifty patients were evaluated over a 1-year period. The total estimated cost for an allogeneic HSCT was $12,504. The two most expensive diseases to allograft were non-Hodgkin lymphoma ($11,760 ± $2,236) for the malignant group and thalassemia ($12,915 ± $5,170) for the nonmalignant group. Acute lymphoblastic leukemia ($11,053 ± 2,817) and acute myeloblastic leukemia ($10,251 ± $1,538) were the most frequent indications for HSCT, with 11 cases each. Median out-of-pocket expenses were $1,605, and 1-year follow-up costs amounted to $1,640, adding up to a total cost of $15,749 for the first year. The most expensive components were drugs and laboratory tests.

CONCLUSION

Applying the cost structure described, HSCT is an affordable option for hematological patients living in a developing country.

Hospital length of stay in the first 100 days after allogeneic hematopoietic cell transplantation for acute leukemia in remission: comparison among alternative graft sources

Several studies have shown comparable survival outcomes with different graft sources, but the relative resource needs of hematopoietic cell transplantation (HCT) by graft source have not been well studied. We compared total hospital length of stay in the first 100 days after HCT in 1577 patients with acute leukemia in remission who underwent HCT with an umbilical cord blood (UCB), matched unrelated donor (MUD), or mismatched unrelated donor (MMUD) graft between 2008 and 2011. To ensure a relatively homogenous study population, the analysis was limited to patients with acute myelogenous leukemia and acute lymphoblastic leukemia in first or second complete remission who underwent HCT in the United States. To account for early deaths, we compared the number of days alive and out of the hospital in the first 100 days post-transplantation. For children who received myeloablative conditioning, the median time alive and out of the hospital in the first 100 days was 50 days for single UCB recipients, 54 days for double UCB recipients, and 60 days for MUD bone marrow (BM) recipients. In multivariate analysis, use of UCB was significantly associated with fewer days alive and out of the hospital compared with MUD BM. For adults who received myeloablative conditioning, the median time alive and out of the hospital in first 100 days was 52 days for single UCB recipients, 55 days for double UCB recipients, 69 days for MUD BM recipients, 75 days for MUD peripheral blood stem cell (PBSC) recipients, 63 days for MMUD BM recipients, and 67 days for MMUD PBSC recipients. In multivariate analysis, UCB and MMUD BM recipients had fewer days alive and out of the hospital compared with recipients of other graft sources. For adults who received a reduced-intensity preparative regimen, the median time alive and out of the hospital during the first 100 days was 65 days for single UCB recipients, 63 days for double UCB recipients, 79 days for MUD PBSC recipients, and 79 days for MMUD PBSC recipients. Similar to the other 2 groups, receipt of UCB was associated with a fewer days alive and out of the hospital. In conclusion, length of stay in the first 100 days post-transplantation varies by graft source and is longer for UCB HCT recipients. These data provide insight into the resource needs of patients who undergo HCT with these various graft sources.

Long-term outcome of fludarabine-based reduced-intensity allogeneic hematopoietic cell transplantation for debilitating paroxysmal nocturnal hemoglobinuria

Paroxysmal nocturnal hemoglobinuria (PNH) is characterized by intravascular hemolysis, venous thrombosis, and bone marrow failure. Seventeen patients with debilitating PNH, including 8 who were HLA-alloimmunized, underwent a reduced-intensity allogeneic hematopoietic cell transplantation (HCT). All received cyclophosphamide/fludarabine +/- antithymocyte globulin followed by a granulocyte colony-stimulating factor-mobilized HCT from an HLA-matched relative. Glycosylphosphatidylinositol-negative neutrophils were detectable after engraftment but disappeared completely at a median 100 days after transplantation. With a median follow-up of nearly 6 years, 15 patients (87.8%) survived, all without any evidence of PNH, transfusion independent, and off anticoagulation. Allogeneic reduced-intensity HCT remains a curative therapeutic option for PNH patients who are not candidates for eculizumab treatment.

Costs of allogeneic hematopoietic cell transplantation using reduced intensity conditioning regimens

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.

Prevention of β Thalassemia in Northern Israel - a Cost-Benefit Analysis

Background

β Thalassemia major is characterized by hemolytic anemia, ineffective erythropoiesis and hemosiderosis. About 4% of the world population carries a Thalassemia gene. Management includes blood transfusions and iron chelation. However, this treatment is costly, and population screening may be significantly more cost beneficial.

Purpose

The purpose of the current study is to analyze the cost of running a prevention program for β Thalassemia in Israel and to compare it to the actual expenses incurred by treating Thalassemia patients.

Methods

Three cost parameters were analyzed and compared: the prevention program, routine treatment of patients and treatment of complications. An estimation of the expenses needed to treat patients who present with complications was calculated based on our ongoing experience in treating deteriorating patients.

Results and Conclusions

The cost of preventing one affected newborn was $63,660 compared to $1,971,380 for treatment of a patient during 50 years (mean annual cost: $39,427). Thus, the prevention of 45 affected newborns over a ten year period represents a net saving of $88.5 million to the health budget. Even after deducting the cost of the prevention program ($413.795/year), the program still represents a benefit of $76 million over ten years. Each prevented case could pay the screening and prevention program for 4.6 years.

Cost-effectiveness and clinical outcomes of double versus single cord blood transplantation in adults with acute leukemia in France

Double cord blood transplantation extends the use of cord blood to adults for whom a single unit is not available, but the procedure is limited by its cost. To evaluate outcomes and cost-effectiveness of double compared to single cord blood transplantation, we analyzed 134 transplants in adults with acute leukemia in first remission. Transplants were performed in France with reduced intensity or myeloablative conditioning regimens. Costs were estimated from donor search to 1 year after transplantation. A Markov decision analysis model was used to calculate quality-adjusted life-years and cost-effectiveness ratio within 4 years. The overall survival at 2 years after single and double cord blood transplants was 42% versus 62%, respectively (P=0.03), while the leukemia-free-survival was 33% versus 53%, respectively (P=0.03). The relapse rate was 21% after double transplants and 42% after a single transplant (P=0.006). No difference was observed for non-relapse mortality or chronic graft-versus-host-disease. The estimated costs up to 1 year after reduced intensity conditioning for single and double cord blood transplantation were € 165,253 and €191,827, respectively. The corresponding costs after myeloablative conditioning were € 192,566 and € 213,050, respectively. Compared to single transplants, double cord blood transplantation was associated with supplementary costs of € 21,302 and € 32,420 up to 4 years, but with increases in quality-adjusted life-years of 0.616 and 0.484, respectively, and incremental cost-effectiveness ratios of € 34,581 and €66,983 in the myeloablative and reduced intensity conditioning settings, respectively. Our results showed that for adults with acute leukemia in first complete remission in France, double cord transplantation is more cost-effective than single cord blood transplantation, with better outcomes, including quality-adjusted life-years.

Allogeneic hematopoietic cell transplantation for consolidation of VGPR or CR for newly diagnosed multiple myeloma

Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative approach in patients with multiple myeloma, but its use for consolidation of first remission has not yet been fully explored. Twenty-two myeloma patients with very good partial response (VGPR) or CR received allogeneic peripheral blood grafts as consolidation from HLA-matched donors between 2007 and 2012. Conditioning regimens were fludarabine (30 mg/m(2) i.v. if with bortezomib and 40 mg/m(2) i.v. when without bortezomib, × 4 days) plus melphalan (70 mg/m(2) intravenously × 2 days) with (n=13) or without (n=9) bortezomib (1.3 mg/m(2)). The cumulative incidence of grades II - IV acute GVHD at day 100 was 45% (95% CI: 24-65%) and moderate-to-severe chronic GVHD at 2 years was 46% (95% CI: 19-69%). With a median follow-up of 18 (range, 2-61) months, the 2-year PFS estimate is 74.8% (95% CI: 45-90%), which compares favorably with the 52% (95% CI: 35-66%) after autologous HCT for similar patients (a median follow-up of 30 (range, 9-55) months). We are conducting a phase 2 study to assess the efficacy of allogeneic HCT as post-remission therapy.
