Comparison of Yearly Cost Related to Complications Between Deferasirox and Deferiprone Monotherapy in Thalassemia.

BACKGROUND: Hemoglobin disorders such as thalassemia major have created an economic burden on the health care system. Iron chelation therapy (ICT) is the most expensive cost component in patients with thalassemia. ICT was administered to reduce the toxic effects of iron overload. This study aims to compare the costs of iron chelators as monotherapy in patients with thalassemia major in Indonesia, specifically in Cipto Faculty of Medicine, Universit. METHODS: This is a retrospective analytical observational study. Data were collected from the thalassemia registry from 2016 to 2019. Patients' age, gender, type of thalassemia, and type of iron chelation were recorded. Complications and total annual costs were evaluated. All thalassemia patients aged ≥2 years who were only receiving monotherapy ICT and had no history of therapy switching were eligible. We excluded subjects who moved out to other facilities or lost to follow-up. RESULTS: From a total of 256 subjects, 249 subjects were included. The median age is 28 years old. Both sexes were represented equally. As many as 96.8% of subjects have thalassemia beta. Deferiprone was the most common iron chelator used (86.7%). Complications were observed in the subjects based on 4-year data collection; most of them were cardiomyopathy, diabetes mellitus, delayed puberty, and malnutrition ( P =0.422; P =0.867; P =0.004; and P =0.125, respectively). Deferiprone had a lower mean annual cost of USD 3581 than deferasirox, which had a cost of USD 6004. CONCLUSIONS: Cardiomyopathy, diabetes mellitus, delayed puberty, and malnutrition were the most common complications found in the study. This study showed that deferiprone should be taken as consideration as a drug of choice to treat iron overload in thalassemia provided by Indonesian national health insurance which is less costly despite the probability of complications found after the treatment was given. Further investigations are required to evaluate contributing factors of complications in thalassemia.

A time-driven, activity-based costing methodology for determining the costs of red blood cell transfusion in patients with beta thalassaemia major.

OBJECTIVES: To describe the methodology to estimate the total cost of administration of a single unit of red blood cells (RBC) in adults with beta thalassaemia major in an Australian specialist haemoglobinopathy centre. BACKGROUND: Beta thalassaemia major is a genetic disorder of haemoglobin associated with multiple end-organ complications and typically requiring lifelong RBC transfusion therapy. New therapeutic agents are becoming available based on advances in understanding of the disorder and its consequences. Assessment of the true total cost of transfusion, incorporating both product and activity costs, is required in order to evaluate the benefits and costs of these new therapies. METHODS: We describe the bottom-up, time-driven, activity-based costing methodology used to develop process maps to provide a step-by-step outline of the entire transfusion pathway. Detailed flowcharts for each process are described. Direct observations and timing of the process maps document all activities, resources, staff, equipment and consumables in detail. The analysis will include costs associated with performing these processes, including resources and consumables. Sensitivity analyses will be performed to determine the impact of different staffing levels, timings and probabilities associated with performing different tasks. RESULTS: Thirty-one process maps have been developed, with over 600 individual activities requiring multiple timings. These will be used for future detailed cost analyses. CONCLUSIONS: Detailed process maps using bottom-up, time-driven, activity-based costing for determining the cost of RBC transfusion in thalassaemia major have been developed. These could be adapted for wider use to understand and compare the costs and complexities of transfusion in other settings.

Cost Effectiveness of Hematopoietic Stem Cell Transplantation Compared with Transfusion Chelation for Treatment of Thalassemia Major.

Hematopoietic stem cell transplantation (HSCT) is the only cure for thalassemia major (TM), which inflicts a significant 1-time cost. Hence, it is important to explore the cost effectiveness of HSCT versus lifelong regular transfusion-chelation (TC) therapy. This study was undertaken to estimate incremental cost per quality-adjusted life-year (QALY) gained with the intervention group HSCT, and the comparator group TC, in TM patients. A combination of decision tree and Markov model was used for analysis. A hospital database, supplemented with a review of published literature, was used to derive input parameters for the model. A lifetime study horizon was used and future costs and consequences were discounted at 3%. Results are presented using societal perspective. Incremental cost per QALY gained with use of HSCT as compared with TC was 64,096 (US$986) in case of matched related donor (MRD) and 1,67,657 (US$2579) in case of a matched unrelated donor transplantation. The probability of MRD transplant to be cost effective at the willingness to pay threshold of Indian per capita gross domestic product is 94%. HSCT is a long-term value for money intervention that is highly cost effective and its long-term clinical and economic benefits outweigh those of TC.

Healthcare costs and outcomes of managing ß-thalassemia major over 50 years in the United Kingdom.

BACKGROUND: The objective was to estimate the incidence-based costs of treating ß-thalassemia major (BTM) to the United Kingdom's National Health Service (NHS) over the first 50 years of a patient's life in terms of healthcare resource use and corresponding costs and the associated health outcomes. STUDY DESIGN AND METHODS: This was a modeling study based on information obtained from a systematic review of published literature and clinicians involved in managing BTM in the United Kingdom. A state transition model was constructed depicting the management of BTM over a period of 50 years. The model was used to estimate the incidence-based health economic impact that BTM imposes on the NHS and patients' health status in terms of the number of quality-adjusted life-years (QALYs) over 50 years. RESULTS: The expected probability of survival at 50 years is 0.63. Of patients who survive, 33% are expected to be without any complication and the other 67% are expected to experience at least one complication. Patients' health status over this period was estimated to be a mean of 11.5 discounted QALYs per patient. Total healthcare expenditure attributable to managing BTM was estimated to be £483,454 ($720,201) at 2013/14 prices over 50 years. The cost of managing BTM could be potentially reduced by up to 37% if one in two patients had a bone marrow transplant, with an ensuing improvement in health-related quality of life. CONCLUSION: This analysis provides the best estimate available of NHS resource use and costs with which to inform policy and budgetary decisions pertaining to this rare disease.

Haemoglobin disorders in Australia: where are we now and where will we be in the future?

Inherited disorders of haemoglobin (Hb), such as thalassaemia and sickle cell disease (SCD) are common and responsible for significant morbidity and mortality on a global scale. As Australia becomes increasingly ethnically diverse, their prevalence will increase. However, we lack important demographic and epidemiological data to manage these disorders and their consequences and to support affected individuals and communities. Thalassaemia and SCD are lifelong conditions. Affected individuals have reduced life expectancies, poorer quality of life and complex healthcare needs. Treatment strategies currently focus on prenatal diagnosis, red blood cell transfusion, iron chelation, management of iron-related complications, haemopoietic stem cell transplantation (HSCT) and hydroxyurea. Currently, the only curative therapy is HSCT; however, gene therapy offers the possibility of cure and trials are currently underway. These therapies are associated with significant complications and substantial costs; there is also evidence of variation in approaches to diagnosis and care. Optimal strategies for many aspects of management are not yet defined and more research is necessary to inform clinical care and health service delivery.

Clinical burden and healthcare resource utilization associated with managing transfusion-dependent ß-thalassemia in France.

OBJECTIVE: To describe the clinical burden and healthcare resource utilization associated with managing transfusion-dependent ß-thalassemia (TDT) in France. METHODS: We used the French National Health Data System (système national des données de santé) to identify eligible patients from January 1, 2012, to March 1, 2019. Inclusion criteria were a diagnosis of ß-thalassemia, ≥8 red blood cell (RBC) transfusion episodes per year in ≥2 consecutive years following the diagnosis, and ≥1 year of follow-up data. Patients were excluded if medical records showed evidence of sickle cell disease, α-thalassemia, hereditary persistence of fetal hemoglobin, or hematopoietic stem cell transplant. Clinical complications, mortality, treatment use, and healthcare resource utilization were evaluated. RESULTS: Overall, 331 eligible patients with TDT were identified. Mean age was 26.1 (standard deviation [SD]: 18.0) years, and 50.5% were male. Common clinical complications were endocrine (26.0%), hepatobiliary (22.7%), and cardiopulmonary (18.7%). Fifteen (4.5%) patients died during follow-up, with a mortality rate of 1.16 deaths per 100 person-years (mean age of death: 52.5 years [SD: 22]). Patients had a mean of 13.5 (SD: 5.2) RBC transfusion episodes and 11.2 (SD: 5.3) iron chelation therapy treatments per year. Healthcare resource utilization was substantial, with a mean of 14.8 inpatient hospitalizations (including 13.8 mean inpatient day cases) and 16.9 outpatient prescriptions per patient per year. CONCLUSIONS: Patients with TDT in France experience significant clinical complications, elevated mortality, and substantial healthcare resource utilization driven by frequent RBC transfusion episodes and inpatient hospitalizations. These results reinforce the need for disease-modifying therapies for this patient population.

Hematopoietic cell transplantation for thalassemia: a global perspective BMT tandem meeting 2013.

Hematopoietic cell transplantation (HCT) remains the sole available curative option for patients with ß-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.

Cost-utility analysis of oral deferasirox versus infusional deferoxamine in transfusion-dependent ß-thalassemia patients.

BACKGROUND: Deferasirox (DFX) is a novel iron chelator that has been shown to have similar efficacy and safety compared with deferoxamine (DFO) in patients with ß-thalassemia. The aim of this study was to determine the cost utility of DFX versus DFO in ß-thalassemia major patients from Iran's society perspective. STUDY DESIGN AND METHODS: A Markov model has been developed to determine lifetime cost and quality-adjusted life-years (QALYs) of patients. To estimate the annual cost of each method, a cross-sectional study was conducted among two groups of patients who received DFO and DFX (n = 100 and n = 45, respectively). Also a time trade-off method was used to estimate the utility of two strategies. Finally a one-way and probabilistic sensitivity analysis was conducted to examine the strength of the results. RESULTS: Our base-case analysis showed that estimated total lifetime costs per patient for DFX and DFO were 47,029 international dollar ($Int) and $Int143,522, respectively, while the estimated total discounted QALYs per person were 12.28 and 7.76, respectively. Calculated incremental cost-effectiveness ratio showed that DSX is a dominant therapy and its estimated lifetime net monetary benefit was $Int273,528. CONCLUSION: We conclude that the use of DFX instead of DFO represents a cost-effective use of resources for treatment of iron overload in patients with ß-thalassemia from Iran's society perspective.

Reproductive behaviour of mothers of children with beta-thalassaemia major.

Thalassaemia is the most common monogenic autosomal hereditary disease worldwide. This questionnaire-based cross-sectional study looked at the reproductive behaviour of 156 mothers of children affected with beta-thalassaemia major (Cooley anaemia) in Fars province, southern Islamic Republic of Iran. Regardless of the number of affected children, the parents of children with Cooley anaemia had an average of 3 unaffected children, the same as the average for the provincial population. The findings indicate that reproductive compensation occurs in families with a child with Cooley anaemia in this province. Genetic counselling, either before marriage or after the birth of the first affected child, had a significant effect on lowering the number of children born.

Health-related quality of life and financial impact of caring for a child with Thalassaemia Major in the UK.

BACKGROUND: Thalassaemia Major (TM) is a serious condition characterized by life-long dependence on blood transfusions and chelation therapy. Our aim was to determine health-related quality of life (HRQOL) in children with TM living in the UK, and the impact of caring for a child receiving National Health Service treatment on family finances. METHODS: This was a cross-sectional assessment of HRQOL in children (n= 22) with TM aged 8-18 years. Children were recruited from three UK Paediatric Haematology and Bone Marrow Transplant centres. Mothers completed measures of their child's HRQOL [PedsQL 4.0 (Measurement Model for the Pediatric Quality of Life Inventory, James W. Varni PhD, PedMetrics, Quantifying the Qualitative SM, Copyright 1998-2009)] and behaviour (Strengths and Difficulties questionnaire), and the impact of caring for the child on family finances. RESULTS: Child behaviour was within the normal range but child HRQOL was significantly lower than population norms. Family financial concerns associated with TM were associated with poorer child HRQOL (P= 0.020). CONCLUSIONS: Thalassaemia Major poses a considerable challenge to child HRQOL, well documented in areas of the world where TM is prevalent. Despite the availability of National Health Service care and financial benefits our study suggests a similar burden in the UK.

[Epidemiological and economic aspects of chelating therapy in the therapeutic center of thalassemia in Morocco]. / Aspects épidémiologiques et économiques des traitements chélateurs au centre thérapeutique de la thalassémie au Maroc.

The study aims to give a general idea about the new experience of chelating drugs among beta-thalassemia patients. It is a declarative survey. It was done in the therapy center of Morocco. Statistics were done in the Laboratory of Biological Essays in Kenitra. All economic and pharmacological data were given by Novartis. Sample size was 89. The only treatment available now in the therapy center is deferiprone. 78% of patients attending the service regularly take deferiprone as treatment while 13% of them combine deferiprone and deferoxamine. Most of the patients take treatments regularly. Chelators have reduced mortality. Patients taking deferoxamine experienced injection site reactions. Most of ADR due to deferiprone were digestive. In conclusion, the main problem with chelators in Morocco is lack of accessibility to drugs (except for some patients insured or payant).

Health state utilities associated with treatment for transfusion-dependent ß-thalassemia.

OBJECTIVES: Transfusion-dependent ß-thalassemia (TDT) is a genetic disease that affects production of red blood cells. Conventional treatment involves regular red blood cell transfusions and iron chelation, which has a substantial impact on quality of life. While potentially curative, allogeneic hematopoietic stem cell transplantation (allo-HSCT) is associated with risk of complications, including graft-versus-host disease (GvHD). Gene addition therapy, a novel treatment approach, involves autologous transplantation of the patient's own genetically modified hematopoietic stem cells. The purpose of this study was to estimate utilities associated with treatment approaches for TDT. METHODS: General population respondents in England valued eight health state vignettes (developed with clinician, patient, and parent input) in time trade-off interviews. RESULTS: A total of 207 participants completed interviews (49.8% female; mean age = 43.2 years). Mean (SD) utilities for the pre-transplant health states were 0.73 (0.25) with oral chelation and 0.63 (0.32) with subcutaneous chelation. Mean utilities for the transplant year were 0.62 (0.35) for gene addition therapy, 0.47 (0.39) for allo-HSCT, and 0.39 (0.39) for allo-HSCT with acute GvHD. Post-transplant utilities were 0.93 (0.15) for transfusion independent, 0.75 (0.25) for 60% transfusion reduction, and 0.51 (0.38) for chronic GvHD. Acute and chronic GvHD were associated with significant disutility (acute = - 0.09, p < 0.0001; chronic = - 0.42, p < 0.0001). CONCLUSIONS: Utilities followed expected patterns, with logical differences between treatment options for TDT and substantially greater utility for transfusion independence than for ongoing treatment involving transfusion and chelation. These utilities may be useful in cost-utility models estimating the value of treatments for TDT.

Update on survival in thalassemia major.

Long-term follow-up of cohorts of patients treated in high-income countries has shown a progressive improvement in life expectancy. Myocardial toxicity from iron overload has been the major cause of mortality; however, there has been a substantial decline in cardiac deaths in recent years, related to switching high-risk patients from subcutaneous desferrioxamine to chelation regimes which include the oral chelator deferiprone. The role of deferasirox in enhancing life expectancy is yet to be determined, but it is reasonable to expect an improvement compared with past experience with desferrioxamine. Other causes of mortality will become an increasingly important issue for older thalassemic patients: Surveillance, prophylaxis, and prompt treatment of infection remains essential, and chronic hepatitis virus infection should be managed with best available current therapies. More data on follow-up of thalassemic patients in middle income countries are needed to demonstrate a similar trend in improved survival. The life expectancy for those in low-income countries is similar to the situation 50 years ago in Europe and the United States. The global thalassemia and public health community should consider how to respond to this disparity.

Results of the national program for prevention of beta-thalassemia major in the Iranian Province of Mazandaran.

Prevention programs are considered to be a top priority in Iran because beta-thalassemia (beta-thal) major (TM) is the most common autosomal disorder in Iran, and in the Mazandaran Province in particular. The main strategies comprise providing appropriate information for the public and professionals, screening and counseling of families at-risk and screening of general population prior to marriage. Providing laboratories for prenatal diagnosis was the most recent step in the program. We report the results of our prevention campaign for the period 1993-2006 in order to assess the effectiveness of all actions in controlling thalassemia major. In 1993, 500 TM patients were registered at the clinic of the Boo Ali Sina Hospital, Sari, Mazandaran, Iran. From 1993 to 1996, on average of 50 new cases were added to the cohort annually, whereas from 1995 to 2005 the number of new cases declined to 35 per year. Furthermore, the patients' average age increased. Overall, 51% of couples at-risk, who received genetic counseling, decided not to marry. All at-risk couples who are married were counseled for prevention of unplanned pregnancies. Currently, 64% are using safe contraceptive methods of family planning, and 14% are no longer at-risk for further pregnancies, the rest remained at-risk for unplanned pregnancies. In conclusion, at the relatively low cost of premarital screening and genetic counseling, we have offered at-risk couples the possibility of preventing the birth of at least 600 undesired TM patients. Thus, a great deal of suffering and an unbearable financial burden has been prevented to patients and their families.

Cost-Utility Analysis of Three Iron Chelators Used in Monotherapy for the Treatment of Chronic Iron Overload in ß-Thalassaemia Major Patients: An Italian Perspective.

PURPOSE: Deferiprone (DFP), deferasirox (DFX) and deferoxamine (DFO) are used in thalassaemia major (TM) patients to treat chronic iron overload. We evaluated the cost-effectiveness of DFP, compared with DFX and DFO monotherapy, from an Italian healthcare system perspective. METHODS: A Markov model was used over a time horizon of 5 years. Italian-specific cost data were combined with Italian efficacy data. Costs and quality-adjusted life years (QALYs) were calculated for each treatment, with cost-effectiveness expressed as cost per QALY. RESULTS: In all scenarios modelled, DFP was the dominant treatment strategy. Sensitivity analyses showed that DFP dominated the other treatments with a >99% likelihood of being cost-effective against DFX and DFO at a willingness to pay threshold of €20,000 per QALY. CONCLUSIONS: DFP was the dominant and most cost-effective treatment for managing chronic iron overload in TM patients. Its use can result in substantial cost savings for the Italian healthcare system.

Financial burden of national health insurance for treating patients with transfusion-dependent thalassemia in Taiwan.

The thalassemias are a heterogeneous group of inherited hypochromic anemias of varying severity. The mainstay of supportive treatment is regular blood transfusion accompanied by iron-chelating therapy. Hematopoietic stem cell transplantation (HSCT) provides an alternative option when curative therapy is considered. More than 400 patients in Taiwan have beta-thalassemia major or other transfusion-dependent thalassemias, and their treatment costs account for a considerable percentage of the National Health Insurance expenditure. In this report, we estimated the treatment costs of conventional therapy (regular blood transfusion accompanied by iron-chelating agents) and HSCT. The undiscounted medical cost of 20 years of follow-up (20 years from diagnosis) and the undiscounted total lifetime cost were NT$ 4 739 888 (NT$ means New Taiwan Dollars)/US$ 149 288 and NT$ 11 529 990/US$ 363 149, respectively, for patients undergoing conventional therapy, and NT$ 2 639 982/US$ 83 149 and NT$ 3 511 172/US$ 110 588, respectively, for those undergoing successful HSCT. Comparisons of treatment costs and other parameters between these two modalities can add to the information base on which policy is made by health authorities or clinicians.

Economic Burden of Thalassemia Major in Iran, 2015.

BACKGROUND: Major Thalassemia is an autosomal recessive disease with complications, mortality and serious pathology. Today, the life expectancy of patients with major thalassemia has increased along with therapeutic advances. Therefore, they need lifelong care, and caring for them would incur many costs. Being aware of the patients' costs can be effective for controlling and managing the costs and providing efficient treatments for the care of patients. Hence, this study was conducted to estimate the economic burden of the patients with major thalassemia. METHODS: Totally, 198 patients with major thalassemia were randomly selected from among the patients with major thalassemia in Tehran, Iran in 2015. The economic burden of the patients was estimated from a social perspective and through a bottom-up, prevalence-based approach. RESULTS: The average annual cost per patient was estimated $ 8321.8 regardless of the cost of lost welfare. Of this amount, $ 7286.8 was related to direct medical costs, $ 461.4 to direct non-medical costs, and $ 573.5 to indirect costs. In addition, the annual cost per patient was estimated $ 1360.5 due to the distress caused by the disease CONCLUSIONS: Considering the high costs of the treatment of patients with major thalassemia, adopting new policies to reduce the costs that patients have to pay seems necessary. In addition, making new decisions regarding thalassemia screening, even with higher costs than the usual screening costs, can be useful since the costs of treatment are high.
