Abstract: Rare, chronic diseases such as hemophilia and other congenital coagulation disorders require coordinated delivery of services for optimal outcomes. Hemophilia Treatment Centers (HTCs) are specialized, multidisciplinary health-care centers providing team-based care to meet the physical, psychosocial, and emotional needs of people with hemophilia (PWH) and may serve as a model for other rare coagulation disorders. Health-care purchasers, as well as the general medical community, may not appreciate the breadth and quality of services provided by HTCs. They exemplify the acculturalization and actualization of integrated care by providing comprehensive diagnostic and treatment services that reduce morbidity, mortality, avoidable emergency room visits, hospitalizations, and overall costs, while promoting a longer lifespan and improved patient functioning and outcomes. This is accomplished by a team-based approach relying upon a shared decision-making model to effectively prevent complications and manage symptoms in PWH, who are dependent on high-cost treatments. This article provides a concise yet comprehensive description of the core components of an HTC and the regional and national networks in the United States, which together achieve their incomparable value for all stakeholders.

Plain Language Summary
Hemophilia Treatment Centers (HTCs) and the regional and national network to which they each belong deliver integrated, patient-centered care that reduces morbidity, mortality, and overall costs, while promoting a longer lifespan and improved outcomes. However, a comprehensive presentation of the HTC Network of care in the United States has not been published since 2005.
During the intervening years, there have been dramatic changes in the diagnosis and treatment of hemophilia and other rare coagulation disorders and rapid evolution in the importance of patient-centered, integrated, value-oriented care. For example, there is more widespread acceptance of prophylaxis as the standard of care for severe hemophilia and there are many more factor and non-factor therapies available for patients to consider. In addition, there has been a dramatic shift in the patient populations served by HTCs, including many more middle-aged and older adults, women, and people with other rare coagulation disorders. Moreover, there are new organizations, such as the American Thrombosis and Hemostasis Network (ATHN), that did not exist in 2005 and which now play a central role, and advances in information technology and telemedicine that have revolutionized the ways in which care is provided.
This article was written to help inform the medical and public health communities about the inner workings of a complex but highly coordinated approach to delivery of health-care services to this unique population, and to advance widespread recognition of the benefits of this model of care to ensure that sufficient funding and support continues into the future.
Hemophilia is a rare inherited, bleeding disorder caused by a deficiency of coagulation factor VIII (FVIII) or factor IX (FIX), known as hemophilia A or B, respectively. The prevalence (per 100,000 males) is 17.1 cases for all severities of hemophilia A, and 3.8 for hemophilia B.1 Bleeding occurs most commonly in joints, soft tissues, and muscles; it can be serious, causing debilitating pain and musculoskeletal complications, resulting in morbidity or even death.1,2 Acute and chronic complications result in a major impact on health-related quality of life (HRQoL) for people with hemophilia (PWH).2 The mainstay of treatment in PWH is intravenous factor replacement therapy, for either prevention of bleeding (prophylaxis) or its treatment on demand.1 Prophylaxis has been proven to maintain joint status and function but requires maintenance therapy over a lifetime.3 Moreover, PWH who develop hemophilic arthropathy require a multimodal approach, including medical treatment, surgery, rehabilitation, and exercise.4 Women with hemophilia and bleeding require the same care as males during hemostatic challenges such as surgery, pregnancy, childbirth, and menstruation.5
Over the past 4 decades, Hemophilia Treatment Centers (HTCs) have emerged as specialized, multidisciplinary health-care centers with unique expertise to meet the physical, psychosocial, and emotional needs of PWH and other congenital coagulation disorders. Optimal outcomes are achieved with a team-based, multidisciplinary, shared decision-making model. Specifically, HTCs offer integrated and comprehensive diagnostic and treatment services, including prevention education, counseling, case management, care coordination, outreach, research, surveillance, and outpatient pharmacy services. These services ensure that PWH and other congenital coagulation disorders have access to highly specialized care to reduce morbidity and enhance wellness, promote a longer lifespan, and improve patient/family functioning; while at the same time reducing avoidable emergency room visits, hospitalizations, and overall costs.6,7
In 2020, the last full year for which we have complete data, HTCs in the United States (US) provided care for 37,541 people with bleeding disorders, compared with 25,450 in 2012.8 In the US, HTCs are at a crossroads: hemophilia treatment is rapidly evolving toward greater complexity, utilization of HTC services by those with other congenital coagulation disorders is on the rise,9 and the generation of sufficient revenue to fund integrated care services has moved to the forefront.10–13 The evolution and increased complexity of hemophilia treatment, coupled with the introduction of precision medicine principles, molecular medicines, and requisite surveillance to monitor these developments, along with the ability to provide sufficient education to engage in shared decision-making, requires ever more expertise on the part of clinicians to ensure that PWH receive state-of-the-art care as HTC teams incorporate these advances.14
Furthermore, several populations are growing overall HTC utilization. First is the increasing number of PWH who reach older ages over the last 20 years.15 Previously, viral contamination of hemophilia medications with both hepatitis C and human immunodeficiency virus (HIV) decimated the community.16 Viral comorbidities, plus progressive painful musculoskeletal deterioration, combine with aging to add complexity to the population’s disease management.17 The lifespan of PWH has extended from 13 years in the early 1900s to approximately 70 years today.18 Finally, HTCs are increasingly serving diverse populations: between 1990 and 2010, the number of women treated at HTCs has increased by 346%, and the proportion of other congenital coagulation disorders, such as von Willebrand disease (VWD), has also substantially increased.9
Purchasers of health care, as well as the general medical community, may not have a complete appreciation of the breadth and quality of services provided by US HTCs. This article is intended to provide a concise yet comprehensive description of the core components of all US HTCs and illustrate how they function as a highly effective national network within a regional structure. Furthermore, it articulates for all stakeholders the value chain of services resulting in the lowest total cost of care while achieving optimal health outcomes for affected individuals and families.
The HTC Model
HTCs provide value to PWH and other congenital coagulation disorders, their caregivers, health-care providers (HCPs), insurers, and policymakers in the form of integrated disease management. This integration is possible through a core care team (Table 1) including a hematologist/medical director, nurse coordinator, physical therapist, and social worker, and access to a specialized coagulation laboratory.7,19,20 This is complemented by an extended team, comprising professionals in related disciplines such as orthopedic surgery, as well as nutritionists, genetic counselors, psychologists, and others available upon referral (Table 1, Figure 1).7,21 Other extended team members include those who facilitate research activities at the HTC, such as data managers and clinical research nurses.22

The sustainability of provider expertise is ensured at HTCs, where clinicians focus on congenital coagulation disorders, and where training is regularly provided. Private practice hematologists and health maintenance organizations do not have the clinical experience, teamwork-based model,23 or capacity to make the investment in quality and expertise that HTCs have, nor do they have ready access to clinical trials that most HTCs have.24
Adherence to Clear Guidelines
Guidelines inform and set a foundation for standardization and assurance of baseline levels of care. To this end, the National Hemophilia Foundation (NHF) partnered with McMaster University to develop an evidence-based clinical practice guideline on “Care Models for Hemophilia Management,” which have been implemented at HTCs across the country.19 The current HTC standard of care is in line with these clinical practice guidelines, ensuring consistent care for PWH within the HTC network.22,25 Moreover, HTCs also adhere to treatment guidelines, standards, and recommendations established by the Medical and Scientific Advisory Council (MASAC) of the NHF26 as well as the World Federation of Hemophilia (WFH) Guidelines for the Management of Hemophilia, which include recommendations for 24-hour patient care and access to safe and effective hemostasis products.20
Specialty Coagulation Laboratory Services
Laboratory services and interpretation of test results are a large part of diagnosis, management, and monitoring for PWH and represent a core service in HTCs.27 Large HTCs have their own specialty laboratories, while smaller HTCs have access to the laboratory services at larger HTCs, as well as those of the Centers for Disease Control and Prevention (CDC). Samples can be shipped from centers within the region, or when necessary, to HTCs outside the region. The quality of care of PWH and others with congenital coagulation disorders depends on the highest quality and timeliness of laboratory services. Speed of results and relationship with hospital-based coagulation laboratories as opposed to commercial laboratories is vital to ensuring optimal outcomes for PWH.28
Coordinated Pharmacy Services
Coordination of care reaches beyond communication between HCPs and PWH. Embedding pharmacy services into HTCs enhances care coordination and real-time response, facilitates shared decision-making, and reduces fragmentation that occurs when pharmacy services are handled by a separate entity. Notably, the pharmacies within the HTCs are consistent with the MASAC’s26 minimum standards for specialty pharmacies serving PWH, including knowledgeable staff, comprehensive access to ancillary services and medications that treat hemophilia, timeliness, accuracy, accessibility, safety, and thoroughness.29 Most HTCs participate in the federal 340B program, a discounted prescription drug purchasing program, and are registered with Health Resources Services Administration (HRSA) as comprehensive HTC 340B programs (https://www.hrsa.gov/opa/index.html). In accordance with the principal aim of the program to enable covered entities to reach more patients and provide more comprehensive services, any income generated through 340B drug discounts is to be used for the direct benefit of PWH, thereby providing a critical revenue stream to support HTC services including patient care and education, staff salaries, and care coordination.30
Although PWH may use any pharmacy allowed by their insurer, using the HTC pharmacy facilitates case management and the opportunity for collaboration between the patient and the medical and pharmacy teams, enabling more agile care coordination in real time, ensuring accurate and complete reporting while achieving the lowest total cost of care and optimal health outcomes.31,32
HTCs Function Within a National Network
In addition to the expertise within each HTC, their value is enhanced by the existence of the US Hemophilia Treatment Center Network (USHTCN), which supports fully integrated and consistent disease management and education across all HTCs. The network not only provides operational organization and administration of HTCs, but also facilitates education and training of HCPs and PWH.25
Eight regional HRSA grantees administer and support 149 HTCs, comprising the USHTCN.33 Core centers serve many functions including disbursement of funds and monitoring to ensure that HTCs conform to the HRSA and CDC requirements.29 Regional HTC networks are administered via a Regional Director and Regional Administrator, roles with standardized responsibilities in accordance with the HRSA and the CDC. Regional core centers organize Executive Committees, promulgate policies and procedures, convene ad hoc working groups, engage with partners, and liaise with community-based organizations. These functions provide a consistent foundation for organized communication and education among and between HTCs.34
Provider Education and Training
Within the United States, there are a limited number of expert HCPs who are concentrated in the 149 US HTCs, necessitating a highly organized and efficient network model to maximize these scarce resources and support cost-effective educational opportunities. The WFH Guidelines also acknowledge this need and recommend networking strategies to provide educational opportunities benefiting HCPs including regional conferences, discipline-specific work groups, information distribution lists, shadow-experiences in HTC clinics, and mentorship of new colleagues.20 Beyond educating HCPs who are focused on treating people with congenital coagulation disorders, the network model also supports the education of community physicians and physical therapists, homecare nurses, emergency room staff, school personnel, and others.11,34,35
In summary, the USHTCN provides operational organization and excellence to enhance communication and education, thereby creating a living and learning network that constantly evaluates and revises treatment standards and recommendations. For example, only through this network approach could over 35,000 publications in the past decade on various types of coagulation disorders (Figure 2), many of which were generated by HTCs, be assimilated, vetted, and utilized to advance patient care and improve patient outcomes. Importantly, much of this quality improvement is neither reimbursed nor paid for by federal grants and exists as unfunded mandates to ensure the highest quality of care for PWH.
Unique Benefits of Integrated Care Provided by HTCs
Comprehensive Care and Educational Support Across the Lifespan
The operational organization of US HTCs enables responsiveness to patient needs, identifying gaps in care and planning educational opportunities around these gaps. The benefits extend to safety and surveillance efforts to enhance outcomes and HRQoL for PWH by reducing the likelihood of serious adverse events due to the bleeding disorder or its treatment while enhancing shared decision-making and self-sufficiency focusing on the PWH as a partner rather than only as a consumer of health care.34
Treatment plan development beginning in early childhood and extending through adulthood includes disease and treatment education; case management; rehabilitation; genetic counseling and testing; dental and orthopedic care; pain management; and nutritional, psychosocial, and vocational counseling. Education is provided to parents of newborns and continues as children develop the capacity to participate in decisions regarding their own treatment (eg, self-infusion education). HTCs facilitate the transition from adolescent to adult health services and preparedness for health-care independence.34
As adults, PWH are directly engaged in their medical care using the shared decision-making model and are fully supported in their aspiration to live as normal a life as possible with respect to education, employment, physical activity, and all other aspects of living.36,37 Comprehensive case management by the HTC’s core care team enables the provision of genetic testing and counseling, surgical coordination, rehabilitation and physiotherapy expertise, and advanced training.7,38 Across the lifespan, women with bleeding disorders require specialized care that includes attention to heavy menstrual bleeding pre-menopause,39 as well as pre- and post-surgery planning to control for heavy blood loss associated with surgery, pregnancy, and postpartum and during times of spontaneous and traumatic joint bleeding.40–42
The lifespan of PWH is increasing, necessitating development of care expertise for elderly PWH. Three issues associated with aging for PWH are general age-associated disease, motor coordination/falls, and specific symptomatology associated with hemophilia such as renal insufficiency and joint disease increasing the incidence of falls. Elderly PWH express comorbidities associated with general aging, such as obesity and hypertension. However, the presentation of these diseases can look different in PWH than the general population.43,44
Improving Patient Outcomes by Evidence Generation
Comprehensive and strategic collection, curation, analysis, and dissemination of data concerning the care and outcomes of PWH and other congenital coagulation disorders is achieved through a collaboration between the PWH, HTCs, CDC, American Thrombosis and Hemostasis Network (ATHN; https://athn.org/), and the USHTCN. Initially, the focus of this effort was on infectious disease (such as viral hepatitis and HIV) and health complications associated with joint disease, but has expanded to examine specific bleeding complications for women and babies, as well as HRQoL.45–47 For example, the Community Counts Project, administered by ATHN in partnership with the USHTCN, collects data for public health tracking of the complications of congenital coagulation disorders (Table 2).45,48 Near real-time reporting of data in an electronic data visualization tool allows for faster detection of trends and potentially faster response times.45
Table 2 Comparison of the Universal Data Collection and the Community Counts Surveillance Systems
Beyond patient care data, the HTC infrastructure also provides PWH with an opportunity to participate in clinical research trials, including novel therapeutics; this is the standard of care at many centers. For example, from 2012 to 2018, the “My Life, Our Future” (MLOF) Research Repository processed information from over 11,000 male and female participants who contributed their genetic data and biologic samples to create the world’s largest hemophilia scientific resource. This rich dataset was realized through extensive partnership between PWH, ATHN, Bloodworks Northwest, the NHF, and Bioverativ.49 ATHN is currently housing the MLOF Research Repository on behalf of the community. Examples of ongoing projects include understanding the genetic, epigenetic, and antibody signatures of inhibitor responses in PWH, and studying factors associated with bleeding in women with hemophilia.49 Another example of using data to demonstrate better outcomes comes from the 3-year retrospective data abstraction study conducted by the Hemophilia Surveillance System, including data on PWH from 6 states. This study indicated a 40% reduction in mortality in PWH who were treated at HTCs, compared with those treated in other health-care settings.50 Additionally, a 20% reduction in bleed-related hospitalizations among PWH cared for at an HTC who were on a medically supervised self-infusion program was also reported.51 More recently, a small study of PWH in Indiana showed a reduction in the use of emergency department services from 33.3% of those treated outside of an HTC to 17.6% of those who were being treated through an HTC.52
Quality improvement (QI) is also a key function of the network, with a focus on 3 areas: patient engagement, medical home, and adolescent transition. The data and quality metrics are essential; the network continues to strive to improve the principles and practices used to diagnose and treat PWH so that the manifestations of their disease and its complications are minimized to achieve better outcomes and reduce disease burden on the individual and his/her family, while achieving optimal health outcomes at the lowest total cost of care—all steps toward health equity.53
Assessing Patient Satisfaction
Improvements in HRQoL such as reduced unemployment and a reduction in mortality are important outcomes, but patient satisfaction with treatment can have a profound impact on the patient’s experience and subsequent treatment adherence. HTCs conducted national patient satisfaction surveys in 2015 and 2018, with another underway in 2021.54 The 2015 and 2018 surveys engaged 5006 and 4767 PWH, respectively. Nationally, over 90% of respondents, regardless of age, sex, race, ethnicity, diagnosis, disease severity, or where they lived, reported being usually or always satisfied with overall HTC care; components of HTC care (each >90% satisfaction nationally) were core team members, HTC care processes and services, and adolescent transition to adult care guidance.55,56 Addressing patient satisfaction also involves finding areas for improvement. In 2013, the National HTC Patient Needs Assessment Survey was mailed to PWH being actively treated at 129 HTCs. Question topics included management and information, access and barriers to care, coping, resources, and transition. Over 90% of respondents agreed or strongly agreed that care at HTCs was patient centered and reported HTC care as important or very important; <3% reported not receiving the services they need. The survey also identified gaps in care including dietary advice, genetic testing, information on aging with hemophilia, sexual health, and basic needs resources; additionally, minority respondents reported more barriers.57
Focusing on Value of Care and Collaboration with Payers
Integrated care brings value from a public health perspective, in the form of potential cost savings to the system and to PWH, which can dramatically impact HRQoL. Figure 3 illustrates how many of the features of HTC care and its clinical benefits contribute to lowering the total cost of care for PWH treated at an HTC. Payers have acknowledged that they did not fully recognize the comprehensive medical and support services that HTCs provide and the positive impact those services have on patient HRQoL and cost of care.58

Strengthening relationships and fostering mutual understanding between health plans and HTCs could further improve outcomes for PWH while providing a more favorable cost-to-benefit ratio. The Comprehensive Care Sustainability Collaborative (CCSC), initiated by NHF in 2014, has served as a springboard for bringing payers and HTCs together to explore and develop opportunities to work collaboratively and enhance communication and understanding between payers and providers to assure optimal patient outcomes at the lowest total cost of care.11 As of 2020, the CCSC advisory board comprises a wide-ranging group of stakeholders, including medical and operational directors representing 8 HTCs, national and regional health plans, and the voice of the self-funded employer. One key learning from the CCSC inaugural consensus meeting was that HTCs are providing a level and range of multidisciplinary care that is far more comprehensive than what has generally been recognized by purchasers of health-care services. After multiple iterations in the CCSC, participants agreed on 2 sets of reporting metrics (payer and HTC). These metrics are being assessed in pilot programs (Table 3).59
Table 3 Final HTC- and Payer-Reported Metrics for Use in Pilot Programs
Advocating for PWH Locally, Regionally, and Nationally
HTCs are actively involved in collaborating with the NHF and other patient advocacy organizations to advance the interests of PWH and their families.60 Families and PWH rely on the NHF for its infrastructure, which includes 50 chapters that provide community support. Through the NHF and its chapters, families can connect with support networks, essential education, and advocacy efforts. In addition to national advocacy efforts, HTCs build partnerships with local foundations and support advocacy at state and national levels;61 HTC staff serve in many advisory and other leadership capacities locally and at NHF.
Funding Mechanisms for HTCs
HRSA has identified specific criteria to qualify for a limited grant; these criteria ensure consistency within the network and support a specific standard of care at each center. HTCs that receive HRSA grant funding are required to provide evidence of optimal care using a multidisciplinary team-based approach.62
With the passage of the Veterans Health Care Act of 1992, regional HRSA grantees and subcontracting HTCs were included as entities eligible to participate in the 340B drug discount program. Though HTCs receive some federal support, they depend on revenue from their pharmacy programs to help finance clinical, educational, counseling, surveillance, and many laboratory services. Most of the federally designated comprehensive HTCs with established 340B programs who participated in a survey indicated that they rely on their 340B-associated income to help fund the staff hours of their on-site social workers, physical therapists, and nurses.30 At issue is the fact that many essential facets of integrated care that are typically delivered via the HTC staff are not billable or are minimally billable. For example, 29 centers in the survey reported that in 2013 alone, 62,640 medical coordination encounters and 57,072 urgent/emergent telephone triage encounters occurred, most of which were non-billable services. In the same survey, 28,880 encounters for psychosocial and vocational services were provided by 30 centers in 2013, again mostly non-billable.30
Charting a Course for the Future of HTC-Based Care
The HTC model can be adapted to the changing health-care needs of PWH as it is primed to take advantage of the evolving technology of the twenty-first century. For example, telehealth and telemedicine at HTCs help to overcome access barriers, allowing HTC care to be offered to anyone regardless of their proximity to a center. These interventions are supported by preliminary evidence of their feasibility and effectiveness, especially for those who face transportation, mobility, or economic barriers, either in the United States or in developing countries;63 however, the benefits remain to be conclusively demonstrated. Telemedicine increases opportunities for collaboration, promoting communication between HTC staff and local HCPs to ensure seamless care.64
One example of successful telehealth implementation includes telerehabilitation for people who need musculoskeletal rehabilitation. Telerehabilitation can greatly improve a patient’s experience and attitude toward essential physical movement needed for recovery. Videoconferencing can also be useful for remotely evaluating bleeding or providing integrated care with multiple providers on the line at the same time.65 The third national HTC Patient Satisfaction Survey, underway in Q1 2021, asks respondents about satisfaction with telehealth/telemedicine, and the extent to which COVID-19 was a barrier to obtaining needed HTC services. Adding these questions illustrates the capacity of the USHTCN to rapidly assess its ability to respond to emerging events (eg, the pandemic) from the patient perspective in a uniform way across centers nationwide.54
Monitoring and self-auditing procedures for PWH in HTCs are also evolving with technology. Cellphone tools and apps have been developed to record information, including details on bleeding episodes, pain, and the use of coagulation factors, potentially allowing for virtual treatment supervision.65 Enhanced real-world evidence collection would stand to improve patient outcomes through increased health surveillance, and potentially offer payers more evidence in support of the advantages of integrated care offered by HTCs.6 HTCs serve PWH and their families who express high satisfaction, a high level of needs met, and improved outcomes spanning HRQoL to cost savings.21,56
The value of the HTC model and the USHTCN are clear; but HTCs are in a state of financial jeopardy, currently heavily reliant on 340B pharmacy-generated income. To continue to provide essential services for PWH and other rare coagulation disorders, it is imperative not only that HTCs receive optimal and fair reimbursement but also that PWH have access to HTCs. Revisions to federal regulations and funding schemes are essential to maintain the quality and level of services currently being offered to PWH. Increased reimbursement for existing billing codes, as well as new codes that more accurately reflect the services delivered, would be an important step toward securing the future of HTCs. Another critical step would be reducing or eliminating exclusionary practices that limit access within health-care networks.
Looking to the future, HTCs are poised to partner on the critical health priorities of the country. With the current structure, HTCs could serve a larger number of people with VWD and other rare coagulation disorders, who currently make use of the integrated care model, along with PWH. Refinement over 40 years has created the foundation for sustainability and the possibility of growth, with the potential for expanded services to PWH and individuals with other rare coagulation disorders that require a similar level of integrated, multidisciplinary care.
People with congenital coagulation disorders have been well served by the HTCs and USHTCN operating in the United States for over 40 years. Herein, we have described what HTCs do and how they do it through a team-based, multidisciplinary approach that incorporates the affected person in shared decision making. We have shown that PWH/caregivers are highly satisfied and have presented evidence for why this model of care has been and will remain the gold standard in the United States. This article can serve as a reference document for all stakeholders in the care of PWH and other rare coagulation disorders. The unique benefits of the HTC network system of care have been clearly demonstrated. Taking all the benefits into account, we believe that purchasers of health care will conclude, as we do, that HTCs provide the highest-quality care for their beneficiaries, delivering optimal health outcomes at the lowest total cost of care.
