The Hemophilia Experiences, Results and Opportunities (HERO) initiative assessed psychosocial issues reported by people with moderate to severe hemophilia and was led by a multidisciplinary international advisory board. This analysis reports data from young adult respondents (aged 18-30 years), including both US and overall global (including US respondents) results, and investigates treatment outcomes, quality of life, and impacts of hemophilia on relationships. More young adults in HERO received prophylaxis than ondemand treatment, although a majority reported not using factor products exactly as prescribed, and 50% of global respondents and 26% of US respondents reported issues with access to factor replacement therapy in the previous 5 years. Many young adults with hemophilia reported comorbidities, including bone/ skeletal arthritis, chronic pain, and viral infections, and nearly half of young adults reported anxiety/ depression. Most reported pain interference with daily activities in the past 4 weeks, although a majority reported participating in lower-risk activities and approximately half in intermediate-risk activities. Most young adults were very or quite satisfied with the support of partners/spouses, family, and friends, although roughly one-third reported that hemophilia affected their ability to develop close relationships with a partner. A majority of young adults reported that hemophilia has had a negative impact on employment, and 62% of global respondents and 78% of US respondents were employed at least part-time. Together these data highlight the psychosocial issues experienced by young adults with hemophilia and suggest that increased focus on these issues may improve comprehensive care during the transition to adulthood.
Objective: To examine the direct and indirect costs of hemophilia care among persons with hemophilia A in the US. Methods:Observational data were obtained from HUGS-Va, a multi-center study from six federally supported hemophilia treatment centers (HTCs). Eligible individuals completed a standardized initial questionnaire and were followed regularly for 2 years to obtain information on work or school absenteeism, time spent arranging hemophilia care, and unpaid hemophilia-related support from caregivers. Data from 1-year healthcare utilization records and 2-year clotting factor dispensing records measured direct medical costs. Indirect costs were imputed using the human capital approach, which uses wages as a proxy measure of work time output. Results:A total of 222 patients with complete data were included in the analysis. Two-thirds had severe hemophilia and the mean age was 21.1 years. The use of prophylaxis in severe hemophilia patients is associated with statistically significant reduction in the numbers of emergency department (ED) visits and bleeding episodes compared with those who were treated episodically. From the societal perspective, mild hemophilia costs $59,101 (median: $7519) annually per person, $84,363 (median: $61,837) for moderate hemophilia, $201,471 (median: $143,431) for severe hemophilia using episodic treatment, and $301,392 (median: $286,198) for severe hemophilia receiving prophylaxis. Clotting factor contributed from 54% of total costs in mild hemophilia to a maximum of 94% for patients with severe hemophilia receiving prophylaxis. Conclusion:Hemophilia is a costly disorder not only because of its high medical expenses, but also due to the high indirect costs incurred.
This study describes health-related quality of life (HRQoL) of persons with haemophilia A in the United States (US) and determines associations between self-reported joint pain, motion limitation and clinically evaluated joint range of motion (ROM), and between HRQoL and ROM. As part of a 2-year cohort study, we collected baseline HRQoL using the SF-12 (adults) and PedsQL (children), along with self-ratings of joint pain and motion limitation, in persons with factor VIII deficiency recruited from six Haemophilia Treatment Centres (HTCs) in geographically diverse regions of the US. Clinically measured joint ROM measurements were collected from medical charts of a subset of participants. Adults (N = 156, mean age: 33.5 ± 12.6 years) had mean physical and mental component scores of 43.4 ± 10.7 and 50.9 ± 10.1, respectively. Children (N = 164, mean age: 9.7 ± 4.5 years) had mean total PedsQL, physical functioning, and psychosocial health scores of 85.9 ± 13.8, 89.5 ± 15.2, and 84.1 ± 15.3, respectively. Persons with more severe haemophilia and higher self-reported joint pain and motion limitation had poorer scores, particularly in the physical aspects of HRQoL. In adults, significant correlations (P < 0.01) were found between ROM measures and both self-reported measures. Except among those with severe disease, children and adults with haemophilia have HRQoL scores comparable with those of the healthy US population. The physical aspects of HRQoL in both adults and children with haemophilia A in the US decrease with increasing severity of illness. However, scores for mental aspects of HRQoL do not differ between severity groups. These findings are comparable with those from studies in European and Canadian haemophilia populations.
The Haemophilia Utilization Group Study (HUGS) was created 10 years ago to examine the annual utilization and cost of haemophilia-related healthcare services. Retrospective chart reviews for 336 patients with haemophilia A receiving treatment in one of five comprehensive haemophilia treatment centres (HTCs) during 1995 were completed through interview of the provider. This method provided adequate collection of data from patient charts without the abstractor having direct access to patient health information. Utilization data were used to impute the costs of different components of care (e.g. physician visits, factor VIII concentrate, emergency room, hospitalization). The total annual cost of care was 139,102 dollars (SD $304,033). Factor VIII concentrate costs comprised the largest proportion of these costs; mean factor VIII concentrate use was 128,517 units per patient per year. Unbilled physician utilization accounted for 7.8% of the mean total physician costs per annum, while mean allied healthcare costs accounted for 33.5% of the total annual allied healthcare costs per patient. In the ordinary least-squares regression model, higher costs were associated with severe factor VIII deficiency, arthropathy, more comorbid conditions, an inhibitor to factor VIII concentrate, infusing through a port and prophylaxis. Although factor VIII concentrate is the most costly component, the treatment of haemophilia uses many healthcare resources. HUGS has demonstrated that patient clinical characteristics and physician practices predominantly drive the costs of haemophilia care. Specifically, patients with more severe arthropathy had greater healthcare costs. As future funding decisions are made, it is important to provide for all components of care.
